Description

TECHNICAL FIELD

[0001] The utility model relates to the field of forage grass processing, in particular to a seed collecting device for forage grass processing. BACKGROUND

[0002] Forage grass, generally refers to the grass or other herbaceous plants for feeding livestock, contains more kinds, generally mainly for the forage grass of gramineae and leguminous plants, forage grass has strong regenerative ability, can be harvested many times a year, rich in various trace elements and vitamins, thus become the first choice for raising livestock. After forage grass matures, it will produce forage grass seeds, the seed harvesting is divided into direct harvesting method, collection harvesting method, segmented harvesting method and ground harvesting method, the specific harvesting method needs to be determined according to the size and growth position of the seed.

[0003] In the prior art, the Chinese utility model patent with publication number CN221381834U discloses a seed collecting device for forage grass processing. During operation, the fixed shaft drives the threshing head to rotate at high speed, and the threshing head strikes or impacts the forage ear part to make the seeds fall off. However, in actual use, multiple threshing heads are arranged axially along the fixed shaft, and a fixed gap is formed between adjacent threshing heads. When the forage ear part enters the threshing area, part of the ear branches or seeds are located at the gap position between adjacent threshing heads. Since the threshing head only rotates in the circumferential direction, its movement trajectory cannot cover these gap areas, resulting in that the seeds in these areas cannot be effectively struck or contacted, forming a threshing blind area, which causes incomplete threshing and low threshing rate. Therefore, we propose a seed collecting device for forage grass processing to solve the above problems. UTILITY MODEL CONTENTS

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A seed collection device for forage processing includes a workbench 1. The workbench 1 is equipped with a first conveyor belt 2 and a second conveyor belt 3 for transporting forage. The surface of the first conveyor belt 2 has block-shaped protrusions, and the surface of the second conveyor belt 3 has strip-shaped protrusions, thereby ensuring a clamping effect on the forage. The transmission method of the first conveyor belt 2 and the second conveyor belt 3 is the same as that of the prior art with publication number CN221381834U, which is a conventional method in the field. Since it is not a major structure, it will not be described in detail here. A through groove 4 is formed on the upper surface of the workbench 1, and the lower surface of the workbench 1 is fixedly connected to... There is a collection box 5 for collecting seeds, and the inside of the collection box 5 is also equipped with structures such as air guide pipes and air nozzles. The existing technology mentioned above can be referred to, so it will not be described again in the text. The inside of the collection box 5 is equipped with three first sleeves 6 for rotation and movement. The outside of the first sleeves 6 is equipped with several mounting rings 7. Several threshing heads 8 for threshing are fixedly connected to the surface of the mounting rings 7. The threshing heads 8 are flexible, so that they can bend and deform when in contact with the forage ears, thereby avoiding rigid impact. The inside of the collection box 5 is equipped with a drive mechanism and a transmission mechanism. The left end of the first sleeves 6 is equipped with a connecting mechanism.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the drive mechanism includes three rotating shafts 9 for rotation. The rotating shafts 9 are rotatably connected inside the collection box 5, and the first sleeve 6 is movably sleeved on the outside of the rotating shafts 9. The surface of the rotating shafts 9 is provided with a synchronization groove 15.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a synchronizing block 16 is fixedly connected to the inner annular surface of the first sleeve 6. The synchronizing block 16 is slidably connected inside the synchronizing groove 15. The first sleeve 6 is slidably sleeved on the outside of the rotating shaft 9 by means of the cooperation between the synchronizing block 16 and the synchronizing groove 15. When the rotating shaft 9 rotates, the cooperation between the synchronizing block 16 and the synchronizing groove 15 can drive the first sleeve 6 to rotate. The rotation of the first sleeve 6 can drive the rotation of the mounting ring 7, thereby driving the rotation of the threshing head 8, and thus achieving the purpose of threshing the forage by the threshing head 8.

[0034] Furthermore, the driving method of the rotating shaft 9 in this solution is the same as the driving method of the fixed shaft in the prior art, which is a conventional solution, so it will not be described again in this article.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the transmission mechanism includes a fixed sleeve 10, which is fixedly connected to the inner wall of the collection box 5. The number of fixed sleeves 10 is matched with the number of rotating shafts 9. An annular chamber 11 is provided inside the fixed sleeve 10. The fixed sleeve 10 surrounds the outside of the rotating shaft 9 through the annular chamber 11. A wave groove 13 is provided on the inner wall of the annular chamber 11. When the rotating shaft 9 and the first sleeve 6 rotate, the rotating shaft 9 will rotate inside the fixed sleeve 10 without interfering with the fixed sleeve 10.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the connecting mechanism includes a second sleeve 12, which is fixedly connected to the first sleeve 6. The second sleeve 12 is movably sleeved inside the fixed sleeve 10, and a guide block 14 is fixedly connected to the surface of the second sleeve 12. The guide block 14 is slidably connected inside the corrugated groove 13. When the first sleeve 6 rotates, it will drive the second sleeve 12 to rotate. Since the guide block 14 is slidably connected inside the corrugated groove 13, it will drive the second sleeve 12 to reciprocate outside the rotating shaft 9, and the first sleeve 6 will also reciprocate outside the rotating shaft 9, ultimately increasing the threshing range, significantly improving the threshing rate, and eliminating threshing dead angles.

[0037] Example 2

[0038] The seed collection device for forage processing provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the inner ring surface of the mounting ring 7 is provided with a telescopic groove 20. A sliding plate 21 is slidably connected inside the telescopic groove 20. A rubber pad 23 is fixedly connected to the lower surface of the sliding plate 21. A bolt 22 is rotatably connected to the upper surface of the sliding plate 21. The upper end of the bolt 22 is threaded through the mounting ring 7. By rotating the bolt 22, the operator can drive the sliding plate 21 and the rubber pad 23 to move inside the telescopic groove 20. After the rubber pad 23 is no longer squeezed against the first sleeve 6, the operator can drive the mounting ring 7 to move outside the first sleeve 6, thereby realizing the adjustment of the distance between each set of threshing heads 8.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the surface of the first sleeve 6 is provided with equidistant scale lines 24. With the help of the equidistant scale lines 24, the accuracy of adjusting the distance between each mounting ring 7 is further improved.

[0040] In this embodiment, for forage grasses with large seeds and sparse ears (such as some legume forage grasses), the spacing can be increased to avoid excessive threshing and energy waste; for forage grasses with small seeds and dense ears (such as some grass forage grasses), the spacing can be decreased to ensure threshing effect, greatly enhancing the versatility of the equipment.

[0041] In addition, in a single operation, the spacing between each threshing head 8 can be set to gradually decrease from the inlet to the outlet. The forage ears first pass through the large-spacing area for preliminary and gentle threshing, and then enter the small-spacing area for deep and thorough cleaning. This gradient threshing method further reduces the risk of seed damage and optimizes the threshing process.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 1 Figure 2 Figure 3 Figure 4 Figure As shown, a protective cover 17 is fixedly connected to the upper surface of the workbench 1, and a control panel 18 is provided on the outside of the protective cover 17. A mounting bracket 19 is fixedly connected to the lower surface of the workbench 1. The protective cover 17 effectively prevents seeds from splashing, the control panel 18 facilitates operation by the staff, and the mounting bracket 19 facilitates the support and installation of drive equipment such as fans.

[0043] The usage process of the seed collection device for forage processing provided by this utility model is as follows:

[0044] The rotating shaft 9 is driven to rotate by an external drive device. The rotation of the rotating shaft 9, in turn, drives the first sleeve 6 to rotate with the cooperation of the synchronizing block 16 and the synchronizing groove 15. The rotation of the first sleeve 6 drives the installation ring 7 to rotate, thereby driving the threshing head 8 to rotate, thus achieving the purpose of threshing the forage by the threshing head 8.

[0045] Furthermore, when the rotating shaft 9 and the first sleeve 6 rotate, the rotating shaft 9 will rotate inside the fixed sleeve 10, and the rotation of the first sleeve 6 will drive the second sleeve 12 to rotate. Since the guide block 14 is slidably connected inside the wave groove 13, it will drive the second sleeve 12 to reciprocate outside the rotating shaft 9, and the first sleeve 6 will also reciprocate outside the rotating shaft 9, ultimately increasing the threshing range, significantly improving the threshing rate, and eliminating threshing dead corners.

[0046] In addition, by rotating bolt 22, the operator can move sliding plate 21 and rubber pad 23 inside the telescopic groove 20. After the rubber pad 23 is no longer pressed against the first sleeve 6, the operator can drive the mounting ring 7 to move outside the first sleeve 6, thereby adjusting the spacing between each set of threshing heads 8. In a single operation, a gradient threshing effect can be set where the spacing between each threshing head 8 gradually decreases from the inlet to the outlet. The operator can adjust the mounting rings on the three first sleeves 6 located on the inlet side, middle side, and outlet side of the workbench 1 in sequence according to the equidistant scale lines 24 set on the surface of the first sleeve 6. Specifically, regarding the axial position of 7, the spacing of each mounting ring 7 on the first sleeve 6 on the inlet side can be adjusted to the maximum, the spacing of the mounting ring 7 on the middle first sleeve 6 can be adjusted to the medium, and the spacing of the mounting ring 7 on the first sleeve 6 on the outlet side can be adjusted to the minimum. This adjustment is achieved by operating the bolts 22 on each mounting ring 7 in sequence. After the rubber pad 23 is released from the pressure on the first sleeve 6, the mounting ring 7 is slid to the predetermined scale position, and then the bolts 22 are tightened to fix it. With this setting, when the forage passes through the threshing area below the three first sleeves 6 in sequence, it can undergo a gradient threshing process from sparse to dense.
