专利汇可以提供Plow harpoon-type conveyor专利检索，专利查询，专利分析的服务。并且An improved plow is provided for use in a harpoon-type or chip conveyor, the plow having a wide forward end and lateral walls. The lateral walls converge upwardly at the forward or leading portion of the plow and additionally converge rearwardly toward the trailing end. The plow is mounted below a supporting member in the form of a shaft or tube. In an improved embodiment the plow is made of two separate plow members mounted on the support in spaced-apart arrangement. Additionally, a longitudinal slot is provided in the lower wall of the tubular supporting member permitting the vertical flange of a T-shaped rail to be disposed in the slot and to permit the supporting member to slide on and to be guided by bearings mounted on the rail.，下面是Plow harpoon-type conveyor专利的具体信息内容。
1. A plow assembly for use in a harpoon-type conveyor, comprising: a. a supporting member, b. a plow affixed thereto and disposed substantially below said supporting member having a forward end adapted to be positioned to push material to be conveyed in a forward direction along the conveyor on the forward stroke, and a rear or trailing end adapted to slide past the material to be conveyed on the rearward stroke, comprising: 1. a relatively wide forward end wall adapted to engage and push forward material to be conveyed, 2. a pair of lateral walls converging toward each other rearwardly and having a forward portion of each lateral wall adjacent said forward end wall converging upwardly with respect to each other over substantially the entire height of said lateral walls.
2. a pair of lateral walls converging toward each other rearwardly and having a forward portion of each lateral wall adjacent said forward end wall converging upwardly with respect to each other over substantially the entire height of said lateral walls.
2. A plow assembly according to claim 1, wherein said lateral walls have trailing members at the rearward end of said plow converging rearwardly with respect to each other at a greater angle than the rearward convergence of the forward portion of said lateral walls.
2. a lateral wall, the lateral walls of said plow members converging with respect to each other rearwardly and the forward portions of said lateral walls adjacent said forward end walls converging upwardly with respect to each other over substantially the entire height of said lateral walls.
2. a lateral wall, the lateral walls of said plow members converging toward each other rearwardly and the forward portions of said lateral walls adjacent said forward end walls converging upwardly with respect to each other over the entire height of said lateral walls.
3. A plow assembly according to claim 1, wherein said forward end wall is inclined rearwardly over substantially the entire height thereof, thereby imparting a lifting movement to the material being conveyed.
4. A plow assembly according to claim 1, wherein the intermediate portions of said lateral walls are concave outwardly.
5. A plow assembly according to claim 1, wherein said lateral walls each have a diagonal recess provided therein substantially connecting the upper front corners thereof to the lower rear corners thereof, whereby the forward and lower portions of said lateral walls have a greater angle of convergence upwardly, and the upward and rearward portions of said lateral walls have a smaller angle of convergence upwardly with respect to each other.
6. A plow assembly for use in a harpoon-type conveyor which comprises a trough of generally U-shape, guide means disposed along said trough, and at least one plow slidably mounted on said guide means, said plow having a forward end positioned to push material to be conveyed in a forward direction on the forward stroke of said plow, and a rear or trailing end positioned to slide past the material to be conveyed on the rearward stroke, said plow comprising: a. an elongate supporting member, and b. a pair of complementary cooperating plow members affixed thereto and disposed substantially below said supporting member, each plow member comprising:
7. A plow assembly according to claim 6, wherein said lateral wallS have trailing members at the rearward end of said plows converging rearwardly with respect to each other at a greater angle than the rearward convergence of the forward portion of said lateral walls.
8. A plow assembly according to claim 6, wherein said forward end walls are inclined rearwardly over substantially the entire height thereof, thereby imparting a lifting movement to the material being conveyed.
9. A plow assembly according to claim 6, wherein the intermediate portions of said lateral walls are concave outwardly.
10. A plow assembly according to claim 6, wherein said lateral walls each have a diagonal recess provided therein substantially connecting the upper front corners thereof to the lower rear corners thereof, whereby the forward and lower portions of said lateral walls have a greater angle of convergence upwardly with respect to each other and the upward and rearward portions of said lateral walls have a smaller angle of convergence upwardly with respect to each other.
11. A plow assembly for use in a harpoon-type conveyor which comprises a trough of generally U-shape, guide means disposed along said trough in the form of an inverted-T rail having a bottom plate and a vertical flange, and at least one plow slidably mounted on said guide means, said plow having a forward end positioned to push material to be conveyed in a forward direction on the forward stroke of said plow assembly, and a rear or trailing end positioned to slide past the material to be conveyed on the rearward stroke, said plow comprising: a. a tubular supporting member having a longitudinal slot provided in the lower wall thereof and extending along the entire length of said supporting member, and b. a pair of complementary cooperating plow members affixed thereto and disposed substantially below said supporting member and being sufficiently spaced-apart to permit the vertical flange of said guide means to extend therebetween and to be inserted in the longitudinal slot of said supporting member, said plow member comprising:
12. A plow assembly according to claim 11, wherein said lateral walls have trailing members at the rearward end of said plows converging rearwardly with respect to each other at a greater angle than that of the rearward convergence of the forward portion of said lateral walls.
13. A plow assembly according to claim 11, wherein said forward end walls are inclined rearwardly over substantially the entire height thereof, thereby imparting a lifting movement to the material being conveyed.
14. A plow assembly according to claim 11, wherein said lateral walls each have a diagonal recess provided therein substantially connecting the upper front corners thereof to the lower rear corners thereof, whereby the forward and lower portions of said lateral walls have a greater angle of convergence upwardly with respect to each other and the upward and rearward portions of said lateral walls have a smaller angle of convergence upwardly with respect to each other.
15. A plow assembly according to claim 11, wherein said plow members are formed of aluminum.
