Technical Field

[0001] The utility model relates to the technical field of straw crushing, in particular to a straw crushing and feeding structure. Background Art

[0002] The straw feeding structure usually refers to the part of agricultural machinery used to feed the straw into the processing device. The straw feeding structure is an important component of agricultural machinery. Its main function is to feed the harvested straw into subsequent processing equipment such as balers or crushers. In different agricultural machinery, the specific design and working principle of the straw feeding structure may be different, but their basic purpose is to improve the operating efficiency and the quality of straw processing.

[0003] In the prior art, if the amount of straw is large or the humidity is high during the operation, the feeding structure may be blocked. If the overall crushing quality and efficiency are to be improved, such long and wet straw must be screened out, which makes the overall process more complicated and affects the work efficiency. How to invent a straw crushing feeding structure to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a straw crushing and feeding structure, aiming to improve the problem that a large amount of straw or high humidity may cause the feeding structure to be blocked, thereby affecting work efficiency.

[0008] The outer wall of the pressing block is slidably connected to the inner wall of the receiving groove, a mounting block is fixedly connected to one side of the pressing block, a driving groove is opened between the pressing block and the mounting block, a conveying roller is installed on the inner wall of the pressing block, a motor is installed on one side of the mounting block, and a main shaft is installed on the inner wall of the mounting block.

[0009] Preferably, two sets of sliding blocks slidably connected to the inner walls of the sliding groove are fixedly connected to the outer walls of the pressing block.

[0010] Preferably, one end of the conveying roller close to the driving groove is fixedly connected to a driven gear, and one end of the main shaft close to the driving groove is fixedly connected to a driving gear meshing with the driven gear.

[0011] Preferably, the output end of the motor is fixedly connected to one end of the main shaft, and the outer wall of the main shaft is rotatably connected to the inner wall of the mounting block.

[0012] By adopting the above technical solution, when feeding the straw, the motor is started to drive the conveying roller on one side to rotate, and the outer wall of the conveying roller contacts the straw to generate friction so that the straw can smoothly enter the crusher below for crushing.

[0013] Preferably, a driving bevel gear is fixedly connected to an outer wall of one side of the main shaft, a reciprocating screw is rotatably connected to an inner wall of one end of the mounting block, and a driven bevel gear meshingly connected to the driving bevel gear is fixedly connected to the outer wall of the reciprocating screw.

[0014] Preferably, the outer wall of the reciprocating screw is threadedly connected to the inner wall of the loading frame, and the mounting block is fixedly connected to guide rods slidably connected to the inner wall of the loading frame on both sides close to the reciprocating screw, and the guide rods and one end of the reciprocating screw passing through the loading frame are fixedly connected to limiting blocks.

[0015] By adopting the above technical solution, when the motor drives the conveying roller to rotate, the active bevel gear on one side of the main shaft engages with the driven bevel gear to rotate the reciprocating screw on one side of the main shaft, and the reciprocating screw cooperates with the loading frame to make the pressing block reciprocate in the loading frame.

[0016] The beneficial effects of the utility model are:

[0017] When feeding the straw, the motor is started to drive the conveying roller to rotate. When the conveying roller rotates, the outer wall of the conveying roller contacts the straw to generate friction, so that the straw can smoothly enter the crusher below. At the same time, the active bevel gear on one side of the main shaft meshes with the driven bevel gear below, so that the reciprocating screw cooperates with the inner wall of the feeding frame during the rotation, so that the pressure blocks on both sides move against each other to squeeze the straw, and the straw blocked in the feeding frame is compressed into a whole to increase the contact area and friction with the conveying roller. After that, the pressure blocks move away from each other, and the straw can fall smoothly into the crusher below under the action of gravity, so as to avoid excessive straw and wet straw adhering to the feeding frame to cause blockage during feeding, thereby improving work efficiency.

[0030] Furthermore, two sets of sliders 6 are fixedly connected to the outer walls of both sides of the pressing block 5 and are slidably connected to the inner walls of the slide groove 4.

[0031] It should be noted that: when feeding the straw, the starting motor 11 drives the main shaft 12 to drive the driving gear 14 at one end to rotate, and the driving gear 14 cooperates with the driven gear 10 to rotate the conveying roller 9 inside the pressing block 5. When the conveying roller 9 rotates, the outer wall contacts the straw to generate friction so that the straw can smoothly enter the crusher 1 below.

[0032] Furthermore, a driving bevel gear 13 is fixedly connected to the outer wall of one side of the main shaft 12, a reciprocating screw 15 is rotatably connected to the inner wall of one end of the mounting block 7, the outer wall of the reciprocating screw 15 is fixedly connected to a driven bevel gear 16 meshing with the driving bevel gear 13, the outer wall of the reciprocating screw 15 is threadedly connected to the inner wall of the loading frame 2, and the two sides of the mounting block 7 close to the reciprocating screw 15 are fixedly connected to guide rods 17 slidably connected to the inner wall of the loading frame 2, and the guide rod 17 and one end of the reciprocating screw 15 passing through the loading frame 2 are fixedly connected to a limiting block 18;

[0034] The working principle of this straw crushing and feeding structure:

[0035] When feeding the straw, the starting motor 11 drives the main shaft 12 to drive the driving gear 14 at one end to rotate. The driving gear 14 cooperates with the driven gear 10 to rotate the conveying roller 9 inside the pressing block 5. When the conveying roller 9 rotates, the outer wall contacts the straw to generate friction so that the straw can smoothly enter the crusher 1 below, avoiding the wet straw from adhering to the frame. At the same time, the active bevel gear 13 on one side of the main shaft 12 meshes with the driven bevel gear 16 below, so that the reciprocating screw 15 on the inner wall rotates. During the rotation process, the reciprocating screw 15 Cooperating with the inner wall of the feeding frame 2, the guide rod 17 drives the pressing block 5 as a whole to reciprocate on the inner wall of the feeding frame 2, so that the pressing blocks 5 on both sides move relative to each other to squeeze the straw, and the straw blocked in the feeding frame 2 is compressed into a whole to increase the contact area and friction with the conveying roller 9, thereby improving the efficiency of the conveying roller 9. After that, the pressing blocks 5 move away from each other, and the straw can fall smoothly into the crusher 1 below under the action of gravity, thereby avoiding excessive straw and wet straw adhering to the feeding frame 2 to cause blockage during feeding, thereby improving work efficiency.
