Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to crop straw processing equipment. Background Art

[0002] In order to avoid the pollution of the atmospheric environment caused by the burning of crop straw in the field, and to comprehensively develop and utilize crop straw and turn waste into treasure, in reality, it is necessary to recycle the crop straw scattered in the field. The main recycling method includes beating the crop straw into square bales and transporting them out of the field, and then unbundling and unpacking the straw for processing. At present, the square bales of straw are mainly processed by piston extrusion, and the straw in the bale is tangled and pulled together in a disorderly manner. In production practice, it is found that this type of square bale of straw is very inconvenient to use after unbundling, that is, it is very laborious and difficult to peel off the straw in the bale, the operation is labor-intensive and inefficient. To solve the above problems, thinner sheet straw blocks have been successfully pressed, which solves the problems of piston extrusion straw bales. However, how to mechanically arrange multiple sheet straw blocks into stacks has not been solved, so at present, only manual labor can be used to stack the sheet straw blocks layer by layer into stacks, which still has the problems of high labor intensity and low packaging efficiency. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of using flaky straw blocks into square bales, and study and design an automatic stacking device for flaky straw blocks to achieve the goals of high stacking efficiency, good stacking quality, and labor-saving operations.

[0011] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. A device for automatically stacking flaky straw blocks comprises a main frame 1 disposed on the right side of a sub-frame 7; a feeding support plate 10 is fixedly mounted on the upper end of the sub-frame 7, a stepping motor 12 is installed on the outer corner of the sub-frame 7, a feeding and sending rod 11 is fixedly mounted on the motor shaft of the stepping motor 12, and the feeding and sending rod 11 is located above the feeding support plate 10; a driving shaft 9, a shaft II 16 and a shaft III 15 are sequentially mounted on the upper end of the main frame 1 in parallel and rotatable manner from left to right, the driving shaft 9, the shaft II 16, the shaft III 15 and the feeding support plate 10 are located on the same horizontal plane, a bidirectional hydraulic cylinder 2 is vertically mounted on the lower inner side of the main frame 1, a push plate 14 is installed on the end of the cylinder rod of the bidirectional hydraulic cylinder 2, the push plate 14 is located in the area between the shaft II 16 and the shaft III 15, and a single groove pulley A is fixedly mounted on the same outer end of the driving shaft 9, the shaft II 16 and the shaft III 15 8. Double-groove pulley 5 and single-groove pulley B3, transmission belt A6 is sleeved on single-groove pulley A8 and double-groove pulley 5, transmission belt B4 is sleeved on double-groove pulley 5 and single-groove pulley B3, and stacking frame assemblies 13 are symmetrically mounted on the front and rear parts of the main frame 1 above the push plate 14, and the structure of the stacking frame assembly 13 is: N pins 13-3 are supported and inserted in sequence from top to bottom in parallel with each other in the part between two relatively arranged vertical plates 13-1, and eccentric triangular plates 13-4 are rotatably mounted on the parts of both ends of the pins 13-3 close to the inner wall of the vertical plates 13-1, and the limiting columns 13-2 with the same number as the pins 13-3 are supported and inserted in sequence from top to bottom in parallel with each other at the part above the side of the pins 13-3 between the two relatively arranged vertical plates 13-1, and the eccentric triangular plates 13-4 are in contact and positioning cooperation with the corresponding limiting columns 13-2.

[0012] During operation, the flake straw blocks are fed one by one and placed on the feeding support plate 10, the stepper motor 12 is started, and the rotating motor shaft drives the feeding and sending rod 11 to rotate, and the feeding and sending rod 11 pushes the flake straw blocks on the feeding support plate 10 to the driving shaft 9, and the external rotating power drives the driving shaft 9 to rotate, and drives the shaft II 16 and the shaft III 15 to rotate through the single groove pulley A8, the transmission belt A6, the double groove pulley 5, the transmission belt B4, and the single groove pulley B3 in turn, and the fed flake straw blocks are sent to the inside of the two relatively arranged stacking frame assemblies 13 and located above the push plate 14, and then the flake straw blocks are pushed upward through the push plate 14 by the extension of the two-way hydraulic cylinder 2. When the flaky straw block rises, it contacts the lower inner side of the eccentric triangle plate 13-4 at the lowest end during its rise, and the eccentric triangle plate 13-4 rotates around the pin shaft 13-3 on the vertical plate 13-1 under the action of thrust. When the lower side of the flaky straw block is out of contact with the eccentric triangle plate 13-4, the eccentric triangle plate 13-4 rotates in the opposite direction under the action of eccentric gravity, and is limited by the limiting column 13-2 to return to its original state. At this time, the flaky straw block is supported on the upper end surface of the eccentric triangle plate 13-4. The cycle operation is repeated in sequence, and the stacked flaky straw blocks are pushed upward from the bottom to form a stack. Finally, the two-way hydraulic cylinder 2 pushes them out from the top of the stacking frame assembly 13 to complete the stacking operation.
