Description

Technical Field

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

[0002] In order to ensure the development of agriculture, the state supports agriculture in many aspects. When harvesting crops, usually, harvesting equipment is used to harvest the fruits, and the straw is cut and left in the field, producing a large amount of straw. There are many ways to deal with the straw. The most common one is to crush it and return it to the field to improve the soil structure and enhance the soil's water and fertilizer retention capacity.

[0003] In the existing technology, straw is crushed by a straw crusher, and the straw is processed according to actual needs. Different needs have different requirements for straw crushing. In the existing equipment, if the straw is just crushed and returned to the field, the straw crushing can be carried out in the field. However, in some cases, the straw that does not need to be crushed can be directly returned to the field, and needs to be crushed and processed for other uses. At this time, the size of the straw crushed by the traditional simple crusher cannot be guaranteed. If there are requirements for the size of the straw residue for straw crushing, a filter needs to be added to ensure that the size of the straw residue meets the requirements, but the crushing efficiency becomes lower. The existing equipment needs to be replaced with different equipment in the face of different needs and cannot cope with different needs. Furthermore, a single crushing knife is set in the existing equipment to crush the straw, but the single crushing knife is easily worn out due to continuous work, and its service life becomes shorter.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] See also Figure 1-12 A straw crushing device includes a chassis shell 1, the bottom end of the chassis shell 1 is fixedly connected to a frame 2, and also includes a crushing mechanism, a filtering mechanism and a conveying mechanism. The crushing mechanism is arranged in the chassis shell 1, the conveying mechanism is arranged on the lower side of the frame 2, and the filtering mechanism is arranged between the crushing mechanism and the conveying mechanism;

[0040] The crushing mechanism includes a first crushing blade 33 and a second crushing blade 36, both of which are arranged on the inner side of the chassis shell 1;

[0041] The filtering mechanism includes a first gear 43, a filter screen 47, and a second connecting member 49. The outer side of the first gear 43 is meshedly connected to a gear ring 44. The inner side of the gear ring 44 is fixedly connected to a first connecting member 45 via a rod. A slot is provided in the middle of the first connecting member 45, and a connecting rod 46 is fixedly connected to the slot. The filter screen 47 is provided on the gear ring 44. A limiting rod 48 is fixedly connected to the bottom end of the filter screen 47. The connecting rod 46 passes through a hole in the middle of the filter screen 47 and is bolted to the filter screen 47. The second connecting member 49 is provided on the filter screen 47. A stirring blade 491 is provided on the side end of the second connecting member 49.

[0042] The conveying mechanism includes a second pipe 53 , an auger disc 55 is provided in the second pipe 53 , the second pipe 53 is connected to the first pipe 52 , and a fourth drive motor 51 is provided at one end of the second pipe 53 close to the first pipe 52 .

[0043] The crushing mechanism further includes a first drive motor 31 , which is disposed on the frame 2 . An output end of the first drive motor 31 is fixedly connected to a first rotating shaft 32 , and a first crushing blade 33 is fixedly connected to the first crushing blade 33 .

[0044] A first circular tube 37 is provided on the lower side of the chassis shell 1 . The end of the first circular tube 37 close to the first drive motor 31 is tilted downward, and the upper half of the first circular tube 37 is in communication with the chassis shell 1 .

[0045] The crushing mechanism further includes a second drive motor 34 , which is disposed at one end of the first circular tube 37 away from the first drive motor 31 . A rotating rod is disposed at the output end of the second drive motor 34 , and a second crushing blade 36 is disposed outside the rotating rod.

[0046] Working process:

[0047] Different processing requirements are required for different straws. When only straw crushing and burying is required, the first drive motor 31 is started, so that the first drive motor 31 drives the first rotating shaft 32 to rotate, and the first crushing blade 33 is driven to rotate by the rotation of the first drive motor 31. The first drive motor 31 controls the rotation efficiency of the first crushing blade 33 to reduce single wear.

[0048] The straw is put into the opening of the chassis shell 1 and crushed by the first crushing knife 33. The straw chassis shell 1 that has been processed once falls into the first circular tube 37. At this time, the second drive motor 34 is started, so that the second drive motor 34 drives the second crushing knife 36 through the rotating rod to further process the straw, which is convenient for dealing with straw of different types and states. The secondary crushing reduces the workload of the crushing knife and avoids excessive wear of the tool and shortening of its service life. The straw residue falls into the second pipe 53 through the inclination of the first circular tube 37, and then the fourth drive motor 51 is started, so that the fourth drive motor 51 drives the auger disc 55 to rotate, so that the auger disc 55 transports the straw residue to the exhaust unit 54, and then the exhaust unit 54 transports the straw residue through the pipeline to the designated position.

[0049] Example 2:

[0050] See also Figure 1-12 This embodiment provides a technical solution for a straw crushing device based on the first embodiment: a second rotating shaft 42 is fixedly connected to the first gear 43, and a third driving motor 41 is fixedly connected to the end of the second rotating shaft 42 away from the first gear 43. The third driving motor 41 is arranged on the inner side wall of the chassis shell 1, and the limiting rod 48 is embedded in the groove arranged on the inner side of the chassis shell 1.

[0051] A thread is provided on the outer side of the first connecting member 45, and the first connecting member 45 can be threadedly connected to a threaded cover 495. A slot is provided in the middle of the first connecting member 45. The filter screen 47 is arranged in the chassis shell 1. A fixing plate 492 is rotatably connected to the rear side of the chassis shell 1. A fixing block 493 is fixedly connected to the chassis shell 1, and a limiting block 494 is slidably connected to the fixed block 493.

[0052] The lower side of one end of the first circular tube 37 close to the first driving motor 31 is connected to the first pipe 52 , and the end of the second pipe 53 away from the fourth driving motor 51 is connected to the fan unit 54 .

[0053] Working process: When straw needs to be crushed and combined with other substances to make feed:

[0054] There are requirements for the size of the straw residue. Manually push the limiting block 494 so that the limiting block 494 shrinks into the fixing block 493, then rotate the fixing plate 492 to open it, rotate the threaded cover 495 in the chassis shell 1, and replace the second connecting piece 49, thereby threaded connection for fixing.

[0055] By starting 2, the rotation rate of 32 is increased, thereby improving the crushing efficiency of 33 and improving the crushing quality. When the straw is crushed once by the first crushing knife 33 and falls onto the filter screen 47, the third drive motor 41 is started to rotate the second rotating shaft 42. The rotation of the second rotating shaft 42 drives the first gear 43 to rotate, and then the rotation of the first gear 43 drives the gear ring 44 to rotate. The rotation of the gear ring 44 drives the first connecting member 45, the connecting rod 46 and the second connecting member 49 to rotate in turn, thereby driving the stirring knife 491 to continuously crush the straw residue on the filter screen 47 until the residue is crushed and reaches the filter hole of the filter screen 47, so that the residue size reaches the standard for making feed. After the straw residue falls into the filter screen 47, it is crushed by the second crushing knife 36 and then passes through the first pipe 52 and the second pipe 53 in turn, and is transported to the exhaust fan unit 54 through the auger disc 55.
