专利汇可以提供Hay roll forming machine专利检索，专利查询，专利分析的服务。并且A machine to form compact rolls of hay of substantial size by picking up a swath or windrow of hay and the like from a field, engage it by cooperating upper and lower endless flexible aprons driven in suitable directions to coil the hay into a compact roll while supported upon floor means mounted stationarily in the bottom of the machine to effect baling of all the hay without loss upon the ground. When the roll type bale of hay reaches a predetermined diameter, the upper apron is raised to provide an exit and the lower apron assists in ejecting the bale onto the ground, or the machine can transport it to a desired location for discharge, if desired. The roll is initiated within a space between the upper and lower aprons which in cross-section is wedge shaped, the lesser distance between the cooperating courses of the aprons being adjacent the forward end of the machine, and results in a relatively soft core for the rolls, whereby when ultimate pressure is formed in the finished roll, the core is not unduly compressed.，下面是Hay roll forming machine专利的具体信息内容。

权利要求

1. A mobile hay roll forming machine comprising in combination a frame having forward and rearward ends, wheels on opposite sides of said frame to support the same for mobility over a swath of hay to be formed into a compact roll, rotatable pickup means supported by the forward portion of said frame, power means to drive said pickup means in a direction to pickup said swath, endless lower flexible means supported by said frame and having a substantially horizontal upper course positioned to receive adjacent the forward end of said frame hay picked up from a field by said pickup means, drive means connected to said lower endless flexible means and operable to move said upper course thereof rearwardly and support a roll of hay thereon as the same is being coiled during operation of said machine, an endless upper apron, means on said frame supporting said upper apron and positioning the lower course of said upper apron above said upper course of said lower flexible means to define a roll-forming cavity, the distance between said upper and lower courses being less at the forward end than at the rearward end thereof, thereby to define a wedge-shaped cavity in side elevation having the greater vertical dimension at the rear end, and drive means on said frame for said upper apron connected thereto and operable to move the lower course thereof forwardly and in opposition to the upper course of said lower flexible means, thereby to effect a coiling action upon a swath of hay received from said pickup means.

2. The machine according to claim 1 in which said endless lower flexible means comprises a series of lugged chains spaced transversely apart and guided by means stationarily supported in the lower portion of said frame, said lugged chains engaging the lower portion of a roll of hay while being rotated between said chains and upper apron positively to insure rotation of said roll and also tend to orient the stems and fibers of at least some of said hay in said roll to extend generally circumferentially in said roll.

3. The machine according to claim 2 in which said machine includes means to guide said lower course of said upper apron relative to said lower apron in a direction to define the upper boundary of said wedge-shaped space, said guide means being positioned to be disengaged from said upper apron when the diameter of a roll of hay increases to a size by which the roll causes said upper apron to disengage said guide means.

4. The machine according to claim 3 in which said lower course of said upper apron extends rearward and downward from said guide means prior to discharge of a roll from said machine to cause said upper apron to restrain rearward movement of a roll of hay being formed by said aprons.
