| 摘要 | A dozer blade assembly for tractors including a pair of mounting brackets for attachment to a tractor frame, a push pole attachable to a tractor drawbar, a dozer blade pivotally connected to the push pole, a support member extending from the push pole to the mounting brackets, and eccentric positioning and mounting pins connecting the support member to the mounting brackets, the eccentric nature of the pins allowing for mounting to a variety of tractor frame sizes. Also disclosed are a telescoping push pole and a dozer blade formed of flat sections of material. | ||||||
| 权利要求 | 1. A dozer blade assembly for tractors comprising: a pair of mounting brackets for attachment to a tractor frame; a push pole adapted for attachment to a rear portion of a tractor; an upstanding support member attached to the forward portion of the push pole and adapted to be connected to the mounting brackets by pin means; at least one eccentric pin means connecting the mounting brackets to the support member; a blade-supporting arm pivotally connected to the forward portion of the push pole; blade means attached to the blade-supporting arm; and powered means extending from the support member to the blade means for raising and lowering the blade means. 2. A dozer blade assembly as defined in claim 1 wherein the push pole includes at the rear thereof a yoke section for attachment to a tractor drawbar and a rear extension for attachment to additional equipment. 3. A dozer blade assembly as defined in claim 1 wherein the push pole includes a rear section and a forward section, said sections being telescopically positionable relative to each other to accommodate different tractor lengths. 4. A dozer blade assembly as defined in claim 1 including transport pin receiving means at the lower portion of the support member, said means being adapted to receive a transport pin for supporting the blade-supporting arm when said arm is in a raised position. 5. A dozer blade assembly as defined in claim 1 where the blade means is pivotally connected to the blade supporting arm for selective side-to-side positioning, and including spring-biased pin means for fastening the blade to the blade-supporting arm in a selected position. 6. A dozer blade assembly as defined in claim 1 wherein the eccentric pin means connecting the mounting brackets to the support member comprises a stabbing section and a fastening section, the respective axial center lines of said sections being displaced relative to one another. 7. A dozer blade assembly as defined in claim 6 wherein two eccentric pin means are provided, the fastening sections are fastened to the mounting brackets by threaded means, and the stabbing sections project forwardly from the mounting brackets. |
