Description

Technical Field

[0001] This utility model relates to the technical field of threshing devices, specifically a vegetable seed threshing device. Background Technology

[0002] As a core production material for vegetable cultivation, the purity and integrity of vegetable seeds directly determine the survival rate of subsequent seedlings and crop yield. In large-scale vegetable seed production, threshing is a crucial link between "fruit harvesting" and "seed processing," requiring efficient separation of seeds from impurities such as fruit peels, pods, and straw, while avoiding seed damage.

[0003] In existing vegetable seed threshing devices, the guide plate is usually rigidly fixed below the discharge port by welding or bolts. In actual operation, there is a difference between the capacity of the collection frame and the placement height. When the collection frame is initially empty or the placement height is low, the seeds need to fall freely from a fixed height. Especially for vegetable seeds with small particle size, the impact generated by the high-speed fall can easily cause the seed coat to break and the embryo to be damaged. Therefore, we propose a vegetable seed threshing device. Utility Model Content

[0004] The purpose of this invention is to provide a vegetable seed threshing device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

A spring is wound around the surface of the slide rod above the insert block. Several sets of equally spaced slots are opened on the outer wall of the handwheel. The insert block is inserted into one set of slots.

[0009] Preferably, one end of the spring is welded to the inner wall of the fixed frame, and the other end of the spring is welded to the surface of the insert block.

[0010] Preferably, a support assembly is provided on the unloading device body below the second guide plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, a vegetable seed threshing device includes: a threshing device body 1, a feed inlet 2 fixedly connected to the top of the threshing device body 1, a discharge outlet 3 fixedly connected to the left side of the threshing device body 1, a motor 4 installed at the bottom of the threshing device body 1, the motor 4 providing power to the threshing device body 1, an extension component 5 installed on the discharge outlet 3, the extension component 5 including a first guide plate 51 fixedly connected to the side of the discharge outlet 3, a movable chamber 52 fixedly connected to the bottom of the first guide plate 51, a gear 53 rotatably connected inside the movable chamber 52, and a rack 54 slidably connected inside the movable chamber 52, the rack 54 meshing with the gear 53. A second guide plate 55 is fixedly connected to the top of bar 54. The second guide plate 55 is slidably connected to the first guide plate 51. A handwheel 56 is fixedly connected to the front end of gear 53 on the same axis. A fixed frame 57 is fixedly connected to the outer wall of the first guide plate 51. The fixed frame 57 is located above the handwheel 56. A slide rod 58 is slidably connected inside the fixed frame 57. An insert block 59 is fixedly connected to the bottom of the slide rod 58. The insert block 59 is slidably connected to the fixed frame 57. A spring 510 is wound around the surface of the slide rod 58 above the insert block 59. Several sets of equally spaced slots 511 are opened on the outer wall of the handwheel 56. The insert block 59 is inserted into one set of slots 511.

[0024] In practice, the handwheel 56 is cranked to drive the gear 53 to rotate within the movable chamber 52, and the gear 53 synchronously drives the rack 54 to slide within the movable chamber 52. This causes the second guide plate 55 to slide synchronously on the first guide plate 51 until the guide port of the second guide plate 55 is in contact with the collection frame. At this point, the slot 511 and the insert 59 are aligned. Then, the restoring force of the spring 510 pushes the insert 59 to insert it into the slot 511, thereby achieving the purpose of adjusting the position of the guide plate. This solves the problem that when the guide plate and the collection frame are at a fixed height, the impact of small vegetable seeds falling can easily cause seed coat rupture and embryo damage.

[0025] As a technical optimization of this utility model, one end of the spring 510 is welded to the inner wall of the fixed frame 57, and the other end of the spring 510 is welded to the surface of the insert block 59.

[0026] In practice, when the spring 510 pushes the insert 59 with its restoring force, the two ends of the spring 510 will not rebound within the fixed frame 57 and continuously impact the insert 59 and the fixed frame 57, thus causing noise pollution.

[0027] As a technical optimization of this utility model, a support assembly 6 is provided on the unloading device body 1 below the second guide plate 55. The support assembly 6 includes a fixing plate 61 fixedly connected to the side wall of the unloading device body 1. A slide rail 62 is provided on the side of the fixing plate 61 away from the unloading device body 1. A slider 63 is slidably connected in the slide rail 62. A support plate 64 is fixedly connected to the outer wall of the slider 63. An auxiliary groove 66 is provided in the other end of the fixing plate 61. A telescopic rod 65 is fixedly connected to the top of the support plate 64. The other end of the telescopic rod 65 is fixedly connected to the second guide plate 55. A lead screw 67 is rotatably connected in the auxiliary groove 66. A transmission block 68 is threadedly connected to the lead screw 67. A clamping plate 69 is fixedly connected to the outer wall of the transmission block 68. The clamping plate 69 is slidably connected to the support plate 64. A handle 610 is fixedly connected to one end of the lead screw 67.

[0028] In specific implementation, the telescopic rod 65 is fixedly connected to the second guide plate 55, so that while the second guide plate 55 moves, the slider 63 is simultaneously driven to slide in the slide rail 62 through the support plate 64. This ensures that the position of the collection frame on the support plate 64 and the second guide plate 55 is always aligned. The collection frame is then placed on the support plate 64, and the handle 610 drives the lead screw 67 to rotate in the auxiliary groove 66. The lead screw 67 acts on the transmission block 68, causing the transmission block 68 to drive the clamping plate 69 to translate. The clamping plate 69 pushes the collection frame, so that the support plate 64 and the clamping plate 69 clamp the collection frame. This prevents the collection frame from becoming misaligned during collection, thus ensuring the stability of the collection frame during use.

[0029] As a technical optimization of this utility model, multiple sets of rubber protrusions are fixedly connected at equal intervals on the top of the support plate 64, and a collection frame is placed inside the support plate 64.

[0030] In practice, this can increase the friction between the collection frame and the support plate 64, preventing the collection frame from shifting on the support plate 64, which would cause the support plate 64 and the second guide plate 55 to shift in position and cause the seeds to fall to the ground.

[0031] As a technical optimization of this utility model, a soft pad is fixedly connected to the side surface of the clamping plate 69 facing the support plate 64, and the soft pad is an anti-slip soft pad.

[0032] In practice, this reduces the hard contact between the clamping plate 69 and the collection frame, thereby preventing the clamping plate 69 from clamping the collection frame too tightly, which could damage the surface of the collection frame.

[0033] In use, this invention first uses a hand crank 56 to rotate a gear 53 within a movable chamber 52, which in turn drives a rack 54 to slide within the chamber. Simultaneously, the second guide plate 55 slides on the first guide plate 51 until its guide opening aligns with the collection frame. At this point, the slot 511 aligns with the insert block 59. Then, the sliding rod 58 is released, and the spring 510's restoring force pushes the insert block 59 into the slot 511. This allows for the adjustment of the guide plate's position, solving the problem that when the guide plate and collection frame are at a fixed height, the impact of falling small vegetable seeds can easily cause seed coat rupture and embryo damage.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
