Description

Technical Field

[0001] This utility model relates to the field of straw crushing technology, and in particular to a straw crushing device for agricultural machinery. Background Technology

[0002] Agricultural machinery refers to all kinds of machinery used in crop cultivation and animal husbandry, as well as in the initial processing and handling of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery, and agricultural transportation machinery, etc.

[0003] A search revealed a Chinese patent (CN220235481 U) for a straw crushing device used in agricultural machinery. The device includes a base for fixing various components, a cabinet for agricultural machinery mounted on the upper side of the base, a feed inlet for conveying straw, a conveying plate for transporting the crushed straw inside the cabinet, a hydraulic rod for compressing the straw mounted on the conveying plate, a pressure plate for compression mounted at the output end of the hydraulic rod, a third telescopic rod welded to the inner wall of the cabinet inside, and a first telescopic rod for discharging material welded to the outer side of the cabinet. A baffle that slidably connects to the inner wall of the cabinet is welded to the output end of the first telescopic rod.

[0004] However, the aforementioned straw crushing equipment for agricultural machinery still has shortcomings. The use of two crushing wheels results in poor straw crushing effect, with a large number of large straw particles remaining after crushing, requiring repeated filling and crushing several times, which reduces the crushing efficiency. Therefore, we propose a straw crushing equipment for agricultural machinery to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned shortcomings and to propose a straw crushing device for agricultural machinery.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A straw crushing device for agricultural machinery includes a crushing cylinder 1 for crushing straw. The top of the crushing cylinder 1 is fixedly connected to a feed inlet 2 for feeding straw. A crushing mechanism 3 is provided on the crushing cylinder 1. Two annular cavities 7 are opened inside the crushing cylinder 1. A crushing mechanism 4 is provided between the crushing cylinder 1 and the two annular cavities 7. A dust collection box 51 is fixedly connected to one side of the crushing cylinder 1. A dust collection mechanism 5 is provided on the dust collection box 51.

[0025] Furthermore, refer to Figures 1-3 The crushing mechanism 3 includes a drive motor 32 fixedly installed at the top of the crushing cylinder 1 and a drive shaft 33 rotatably connected to the inner wall of the top of the crushing cylinder 1. The output shaft of the drive motor 32 is fixedly connected to the top of the drive shaft 33, and several crushing blades 34 are fixedly connected to both sides of the drive shaft 33.

[0026] Using the above method: the straw is pushed into the crushing cylinder 1 through the feed inlet 2, and the drive motor 32 drives the drive shaft 33 and the crushing blade 34 to rotate, thereby crushing the straw.

[0027] Furthermore, a mounting bracket 31 is fixedly connected to the top of the crushing cylinder 1, and the drive motor 32 is fixedly connected to the top of the mounting bracket 31, which facilitates the support and fixation of the drive motor 32.

[0028] Furthermore, refer to Figures 1-3The second crushing mechanism 4 includes a rotating ring 409 rotatably disposed in an annular cavity 7, a transmission shaft 404 rotatably disposed between two annular cavities 7, and a left pulley 401 fixedly sleeved on the outside of the drive shaft 33. A right pulley 403 is fixedly connected to the top end of the transmission shaft 404. The left pulley 401 and the right pulley 403 are connected by the same belt 402. Two drive gears 412 are fixedly sleeved on the outside of the transmission shaft 404. An external toothed ring 411 is fixedly sleeved on the outside of the rotating ring 409. The two drive gears 412 mesh with the corresponding external toothed rings 411. Crushing rods 405 are rotatably connected to both sides of the rotating ring 409. Multiple crushing blades 406 are fixedly connected to the outside of the crushing rods 405. A driven bevel gear 413 is fixedly connected to one end of the crushing rods 405. An internal bevel gear 414 is fixedly connected inside the annular cavity 7. The driven bevel gear 413 meshes with the internal bevel gear 414.

[0029] Using the above scheme: Under the transmission of the left and right pulleys and belt 402, the drive shaft 33 drives the transmission shaft 404 and the two drive gears 412 to rotate. The two drive gears 412 drive the two external gear rings 411, the rotating ring 409 and the four crushing rods 405 to rotate in the opposite direction to the drive shaft 33. Under the shearing of the crushing rods 405 and the crushing blades 34, the straw crushing effect is better. At the same time, the revolution of the crushing rods 405 drives the revolution of the two driven bevel gears 413. Under the action of the fixed inner bevel gear 414, the two driven bevel gears 413 will rotate. The two driven bevel gears 413 drive the two crushing rods 405 and the multiple crushing blades 406 to rotate. Through the rotation of the crushing blades 406, the straw can be crushed again, further improving the straw crushing effect and efficiency. The crushed straw particles are discharged from the discharge pipe 6.

[0032] Furthermore, refer to Figure 1 and Figure 4The dust collection mechanism 5 includes a dust outlet pipe 53 fixedly connected between the dust collection box 51 and the pulverizing cylinder 1, a dust collection pump 57 fixedly connected to one side of the dust collection box 51, a collection box 52 slidably fitted inside the dust collection box 51, a filter screen 55 installed inside the dust collection box 51, a baffle screen fixedly connected to one end of the dust outlet pipe 53, an installation port 54 opened on the top of the dust collection box 51, a sealing block 56 slidably fitted inside the installation port 54, and the sealing block 56 fixedly connected to the top of the filter screen 55.

[0033] The above solution is adopted to prevent dust from flying out during crushing. The dust in the crushing cylinder 1 can be sucked into the dust outlet pipe 53 and the dust collection box 51 by the dust pump 57. After being filtered and intercepted by the filter screen 55, the dust falls into the collection box 52 for collection and treatment. The installation port 54 and the sealing block 56 facilitate the regular disassembly, cleaning and replacement of the filter screen 55 to ensure the filtration effect.

[0034] In this invention, during use, straw is pushed into the crushing cylinder 1 through the feed inlet 2. The drive motor 32 drives the drive shaft 33 and the crushing blade 34 to rotate, thereby crushing the straw. Simultaneously, through the transmission of the left and right pulleys and belt 402, the drive shaft 33 drives the transmission shaft 404 and the two drive gears 412 to rotate. The two drive gears 412 drive the two external gear rings 411, the rotating ring 409, and the four crushing rods 405 to rotate in the opposite direction to the drive shaft 33. Under the shearing action of the crushing rods 405 and the crushing blade 34, the straw crushing effect is improved. At the same time, the revolution of the crushing rods 405 drives the revolution of the two driven bevel gears 413, and the fixedly set internal bevel gear 414... Under the action of the two driven bevel gears 413, the two driven bevel gears 413 will rotate, which drives the two crushing rods 405 and multiple crushing blades 406 to rotate. Through the rotation of the crushing blades 406, the straw can be crushed again, further improving the crushing effect and efficiency. The crushed straw particles are discharged from the discharge pipe 6. At the same time, in order to prevent dust from flying out during crushing, the dust in the crushing cylinder 1 can be sucked into the dust discharge pipe 53 and the dust collection box 51 by the dust pump 57. After being filtered and intercepted by the filter screen 55, the dust falls into the collection box 52 for collection and treatment. The setting of the installation port 54 and the sealing block 56 facilitates the regular disassembly, cleaning and replacement of the filter screen 55 to ensure the filtration effect.
