Description

Technical Field

[0001] This utility model belongs to the field of sunflower processing technology, and more specifically, it relates to a sunflower threshing machine. Background Technology

[0002] A sunflower thresher is a mechanical device used during the sunflower seed harvesting process to separate sunflower seeds from the flower head. It mechanically separates the seeds from the mature sunflower head, avoiding the labor-intensive process of traditional manual threshing.

[0003] Some sunflower threshers currently lack an effective seed collection device during processing, resulting in a large number of seeds scattering at the discharge point of the machine. This requires workers to spend a lot of time collecting the seeds, leading to low work efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a sunflower threshing machine, in order to achieve a more practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sunflower threshing machine, which is achieved by the following specific technical means:

[0006] A sunflower threshing machine includes a frame, a first mounting plate installed on one side of the top of the frame, a threshing assembly installed on the top of the first mounting plate, an upper baffle installed on one side of the top of the first mounting plate at a position above the frame, a plurality of guide rods installed on the top of the frame, and the plurality of guide rods being inclined, a sloping discharge plate installed on the inner side of the frame at a position below the plurality of guide rods, a material blocking assembly installed on one side of the frame near the bottom end of the sloping discharge plate, a placement plate installed on one side of the frame near the material blocking assembly, and a first collection box installed on the top of the placement plate.

[0007] Furthermore, the material blocking assembly includes a first mounting base, which is installed on one side of the frame below the inclined material cutting plate. A threaded rod is rotatably mounted on the top of the first mounting base, and the surface of the threaded rod is threadedly connected to the material blocking plate. One side of the material blocking plate is in close contact with one side of the bottom end of the inclined material cutting plate. A pair of limiting rods are installed on both sides of the top of the first mounting base, and the pair of limiting rods pass through the bottom end of the material blocking plate and are slidably connected to the material blocking plate.

[0008] Furthermore, the top of the baffle plate is provided with a slope, and the angle of the slope is the same as the angle of the inclined material plate.

[0009] Furthermore, a first motor is installed at the bottom of the baffle plate, and the output end of the first motor is connected to a threaded rod via a coupling.

[0010] Furthermore, the threshing assembly includes three threshing rollers and a transmission mechanism. The three threshing rollers are rotatably mounted on one side of the first mounting plate, located above a plurality of guide rods. The transmission mechanism includes a pair of synchronous pulleys, a pair of driven pulleys, and a second motor. The pair of synchronous pulleys are mounted at one end of two threshing rollers that are far apart from each other, and the pair of synchronous pulleys are connected by a synchronous belt drive. The pair of driven pulleys are mounted at one end of two adjacent threshing rollers. The second motor is mounted on one side of the frame, and the output end of the second motor is equipped with a drive pulley via a coupling. The drive pulley and the pair of driven pulleys are connected by a transmission belt drive.

[0011] Furthermore, a feed plate is installed on one side of several of the guide rods.

[0012] Furthermore, a filter plate is installed on one side of the frame below the bottom of one of the guide rods, and a second collection box is installed at the bottom of one side of the frame below the filter plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The sunflower thresher of this utility model, through the coordinated use of a frame, a first mounting plate, an upper baffle, a guide rod, an inclined discharge plate, a placement plate, a first collection box, a first mounting base, a threaded rod, a baffle plate, a limit rod, a first motor, a threshing roller, a synchronous pulley, a driven pulley, a second motor, a driving pulley, a feeding plate, a filter plate, and a second collection box, facilitates seed recovery through the first and second collection boxes after sunflower threshing. The upper baffle reduces seed splashing, and the baffle plate obstructs seeds when the worker changes the first collection box, ensuring the machine remains operational. After replacement, the baffle plate descends, allowing seeds to fall back into the first collection box. This improves the thresher's production efficiency, reduces post-collection cleaning costs, and minimizes sunflower and seed waste. Attached Figure Description

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] This utility model provides a sunflower threshing machine, including a frame 1. A first mounting plate 2 is installed on one side of the top of the frame 1. A threshing component is installed on the top of the first mounting plate 2. An upper baffle 3 is installed on one side of the top of the first mounting plate 2 at a position above the frame 1. A plurality of guide rods 4 are installed on the top of the frame 1, and the plurality of guide rods 4 are inclined. An inclined feeding plate 5 is installed on the inner side of the frame 1 at a position below the plurality of guide rods 4. A material blocking component is installed on one side of the frame 1 at a position near the bottom of the inclined feeding plate 5. A placement plate 6 is installed on one side of the frame 1 at a position near the material blocking component. A first collection box 7 is installed on the top of the placement plate 6.

[0026] The material blocking assembly includes a first mounting base 8, which is installed on one side of the frame 1 below the inclined material plate 5. A threaded rod 9 is rotatably mounted on the top of the first mounting base 8, and the surface of the threaded rod 9 is threadedly connected to the material blocking plate 10. One side of the material blocking plate 10 is in close contact with one side of the bottom of the inclined material plate 5. A pair of limiting rods 11 are installed on both sides of the top of the first mounting base 8, and the pair of limiting rods 11 pass through the bottom of the material blocking plate 10 and are slidably connected to the material blocking plate 10. By rotating the threaded rod 9, the material blocking plate 10 moves up and down under the limiting action of the pair of limiting rods 11. When the operator needs to replace the first collection box 7, the material blocking plate 10 can be raised. At this time, the material blocking plate 10 blocks the seeds located on the inclined material plate 5, preventing the seeds from falling further. After the first collection box 7 is replaced, the operator controls the material blocking plate 10 to descend, so that the top of the material blocking plate 10 is in a parallel position with the inclined material plate 5, thereby facilitating the continued feeding of materials.

[0027] The top of the baffle plate 10 is provided with a slope, and the angle of the slope is the same as the angle of the inclined material plate 5, so that the sunflower seeds can fall into the first collection box 7.

[0028] The bottom end of the baffle plate 10 is equipped with a first motor 12, and the output end of the first motor 12 is connected to the threaded rod 9 through a coupling. The first motor 12 drives the threaded rod 9 to rotate, thereby driving the baffle plate 10 to move.

[0029] The threshing assembly includes three threshing rollers 13 and a transmission mechanism. The three threshing rollers 13 are rotatably mounted on one side of the first mounting plate 2, above several guide rods 4. The transmission mechanism includes a pair of synchronous pulleys 14, a pair of driven pulleys 15, and a second motor 16. The pair of synchronous pulleys 14 are mounted at one end of two threshing rollers 13 that are far apart from each other, and the pair of synchronous pulleys 14 are connected by a synchronous belt. The pair of driven pulleys 15 are mounted at one end of two adjacent threshing rollers 13. The second motor 16 is mounted on one side of the frame 1. The output end of the second motor 16 is equipped with a drive pulley 17 through a coupling, and the drive pulley 17 and the pair of driven pulleys 15 are connected by a transmission belt. The second motor 16 drives the drive pulley 17 to rotate, which in turn drives the pair of driven pulleys 15 to rotate together through the transmission belt, causing the two adjacent threshing rollers 13 to rotate together. Then, through the transmission of the synchronous pulleys 14 and the synchronous belt, the other threshing roller 13 rotates together, thereby achieving sunflower threshing.

[0030] Among them, a feed plate 18 is installed on one side of several guide rods 4 to facilitate the placement of sunflowers into the machine.

[0031] A filter plate 19 is installed on one side of the frame 1 at a position below the bottom of several guide rods 4. A second collection box 20 is installed at the bottom of one side of the frame 1 at a position below the filter plate 19, so as to facilitate the collection of sunflower flowers after threshing and to recycle the remaining seeds through the second collection box 20.

[0032] The working principle of this embodiment is as follows: When using this sunflower thresher, the operator first turns on the second motor 16. Through the drive pulley 17, driven pulley 15, transmission belt, synchronous pulley 14, and synchronous belt, the three threshing rollers 13 rotate together. Then, the operator places the sunflowers above the guide rods 4 through the feed plate 18. At this time, the threshing rollers 13 thresh the sunflowers through friction and compression. The threshed seeds fall through the gaps between the guide rods 4 onto the inclined feed plate 5 below and slide into the first collection box 7. The sunflower flowers fall along the guide rods 4 into the filter. On the surface of plate 19, when the first collection box 7 is full, the worker can turn on the first motor 12. The first motor 12 drives the threaded rod 9 to rotate. Under the limiting action of a pair of limit rods 11, the baffle plate 10 moves upward and blocks the seeds on the inclined lower plate 5. Then the worker removes the full first collection box 7 and places the new first collection box 7 on the placement plate 6 and turns on the first motor 12 again, so that the baffle plate 10 descends to a position where its top is parallel to the inclined lower plate 5. At this time, the sunflower seeds are no longer blocked and continue to fall into the new first collection box 7.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
