Description

Technical Field

[0001] This utility model relates to a seed threshing device for harvesting green beans, specifically belonging to the field of green bean threshing technology. Background Technology

[0002] Common beans, also known as kidney beans, are annual, twining, or nearly erect herbaceous plants belonging to the legume family and the genus *Phaseolus*. Common beans are the most widely cultivated crop in the genus *Phaseolus*. The tender pods are used as vegetables. The morphology of the plant, the color and size of the flowers, and the shape and color of the pods and seeds all vary considerably, resulting in different flavors. When selling common bean seeds, there are high requirements for their appearance, so many merchants choose to buy common beans with pods on and then thresh them before selling them.

[0003] Currently, bean threshing is generally done manually, which is very inconvenient. Equipment processing usually involves pounding to separate the beans from the pods, and then using appropriate equipment to separate the two. However, damage can easily occur during the pounding process, and due to the large differences in size in different directions, a large gap needs to be left to avoid damaging the beans with too small a space. However, an excessively large gap may lead to incomplete separation. Utility Model Content

[0004] The purpose of this invention is to provide a seed threshing device for harvesting green beans, in order to solve the problem that green beans are easily damaged during the threshing process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: the new model includes a harvesting box and a threshing box, and also includes a collecting funnel, a stripping component and a threshing component;

[0006] A collection funnel is installed inside the harvesting box, and a collection pipe is connected to the lower end of the collection funnel. A threshing box is installed on the outer side below the collection pipe. A support frame is fixedly installed on the outer wall of the bottom surface of the threshing box. A stripping component is installed inside the collection pipe, and a threshing component is installed inside the threshing box.

[0007] Furthermore, the harvested green beans are collected using a harvesting box, and the beans are guided and discharged into a threshing box using a collection funnel and a collection pipe. The bean pods are cut by a peeling component inside the collection pipe, which facilitates the subsequent threshing process. The bean pods are threshed by a threshing component inside the threshing box, thereby improving the efficiency of green bean threshing.

[0008] The threshing assembly includes a drive motor, a material distribution rod, and a first threshing rod; the drive motor is fixedly installed on the top surface of the support frame by bolts, and the material distribution rod is fixedly connected to the end of the output shaft of the drive motor. The top of the material distribution rod is a conical structure, and the material distribution rod is located inside the threshing box. The first threshing rod is fixedly installed at an equal angle on the outer wall of the material distribution rod.

[0009] Furthermore, by using a drive motor as the driving force for the threshing assembly, and by using a conical structure at the top of the distribution rod, the beans can fall evenly onto the threshing assembly, and the beans are threshed by the first threshing rod.

[0010] The threshing assembly also includes a first gear, a second gear, a drive gear, a connecting rod, and a second threshing rod; the first gear is fixedly installed on the outside of the output shaft of the drive motor, the second gear is connected to one side of the first gear, a support frame is connected to the bottom of the second gear, the drive gear is connected to the other side of the second gear, the connecting rod is fixedly connected to the top surface of the drive gear, the connecting rod is located inside the threshing box, and the second threshing rod is fixedly installed at equal intervals on the side of the connecting rod facing the material distribution rod, and the second threshing rod and the first threshing rod are staggered;

[0011] Furthermore, through the meshing connection of the first gear, the second gear, and the drive gear, the drive gear can drive the second threshing rod to rotate via the connecting rod, and the second threshing rod cooperates with the first threshing rod to complete the threshing process of the green beans.

[0012] The stripping assembly includes a suction pipe, a threaded rod, a threshing blade, a suction motor, and a suction fan; a threaded rod is inserted into the collection pipe from the outside to the inside, one end of the threaded rod is connected to the threshing blade, a suction pipe is connected to one side of the collection pipe, a suction motor is fixedly installed on the inner wall of the suction pipe by bolts, and a suction fan is fixedly connected to the end of the output shaft of the suction motor.

[0013] Furthermore, the suction fan driven by the suction motor allows the beans to smoothly pass through the collection pipe into the threshing box. The threaded rod connected to the collection pipe allows the threshing blades to be adjusted in position, thus avoiding damage to the beans and improving the quality of bean threshing.

[0014] The top surface of the threshing box is provided with a chute for the collection pipe to move, and a discharge port is fixedly installed on one side of the threshing box;

[0015] Furthermore, the beans and pods are collected through the discharge port.

[0016] Springs are connected to both sides of the collecting funnel, and the other end of the springs is connected to the inner wall of the collecting box. The collecting box is designed to open upwards.

[0017] Furthermore, the spring makes the vibration of the collecting funnel more stable.

[0018] The beneficial effects of this utility model are:

[0019] 1. The structure of connecting the threaded rod to the collecting pipe allows the threaded rod to adjust the position of the threshing blade, thereby enabling the threshing blade to cut the bean pods. This facilitates the subsequent threshing of the beans and helps to avoid damaging the beans, thus improving the quality of bean threshing.

[0020] 2. The drive motor can drive the first threshing rod to rotate through the material distribution rod. At the same time, the drive motor can drive the second threshing rod to rotate through the meshing connection of the first gear, the second gear and the drive gear. Since the second threshing rod and the first threshing rod are arranged in an interlaced structure, the second threshing rod and the first threshing rod can cooperate to complete the threshing process of the green beans by pounding, thereby improving the threshing effect of the device.

[0027] The following will be combined with the appendix Figure 1-5 The technical solutions in the embodiments are described clearly and completely.

[0028] Specific implementation method one: as follows Figure 1-3As shown, the overall device consists of a harvesting box 1, a collecting funnel 2, a collecting pipe 3, and a threshing box 4. The collecting funnel 2 is slidably installed inside the harvesting box 1. The collecting pipe 3 is fixedly connected to the lower end of the collecting funnel 2. A vibration module 21 is fixedly installed on the outer wall of the collecting pipe 3. By controlling the vibration module 21, the collecting pipe 3 can drive the collecting funnel 2 to vibrate, so that the collecting funnel 2 can move left and right on the bottom surface of the inner wall of the harvesting box 1. This allows the beans in the collecting funnel 2 and the collecting pipe 3 to fall smoothly into the threshing box 4 set below the outer side of the collecting pipe 3, thereby improving the stability of the device.

[0029] A drive motor 6 is fixedly installed on the top surface of the support frame 5 by bolts. A material distribution rod 7 is fixedly connected to the end of the output shaft of the drive motor 6. The top of the material distribution rod 7 is set with a conical structure. The conical structure at the top of the material distribution rod 7 allows the beans to fall evenly onto the threshing assembly, thereby improving the threshing efficiency of the beans. The first threshing rod 8 is fixedly installed at equal angles on the outer wall of the material distribution rod 7. Eight sets of the first threshing rod 8 are arranged vertically.

[0030] Specific implementation method two: such as Figure 4-5 As shown, a first gear 9 is fixedly installed on the outer side of the output shaft of the drive motor 6. A second gear 10 is meshed with one side of the first gear 9. A support frame 5 is rotatably connected to the bottom of the second gear 10, thereby improving the rotational stability of the second gear 10. A drive gear 11 is meshed with the other side of the second gear 10. Since a connecting rod 12 is fixedly connected to the top surface of the drive gear 11, and a second threshing rod 13 is fixedly installed at equal intervals on the side of the connecting rod 12 facing the material distribution rod 7, and the second threshing rod 13 and the first threshing rod 8 are staggered, the drive motor 6 can drive the second threshing rod 13 to rotate through the meshing connection of the first gear 9, the second gear 10 and the drive gear 11. The threshing of the beans is completed by the cooperation of the second threshing rod 13 and the first threshing rod 8.

[0031] A threaded rod 16 is inserted into the collection tube 3 from the outside in. One end of the threaded rod 16 is rotatably connected to a threshing blade 17. Since the threaded rod 16 is threadedly connected to the collection tube 3, it can drive the threshing blade 17 to adjust its horizontal position, thus helping to avoid damaging the beans. A limit rod is fixedly installed on one side of the threshing blade 17, which improves the stability of the movement of the threshing blade 17.

[0032] A suction pipe 15 is fixedly connected to one side of the collection pipe 3. A suction motor 18 is fixedly installed on the inner wall of the suction pipe 15 by bolts. A suction fan 19 is fixedly connected to the end of the output shaft of the suction motor 18. The suction fan 19 can be driven to rotate by the suction motor 18, so that the beans can pass through the collection funnel 2 and the collection pipe 3 more smoothly into the threshing box 4. Filter screens are fixedly installed at both ends of the suction pipe 15.

[0033] Harvesting box 1 is designed to open upwards and can be fixedly installed on the outside. Springs 20 are connected to both sides of the collecting funnel 2, and the other end of the springs 20 is connected to the inner side wall of the harvesting box 1. The top surface of the threshing box 4 is provided with a sliding groove for the collection pipe 3 to move, thereby improving the stability of the movement of the collecting funnel 2 and the collection pipe 3. A discharge port 14 is fixedly installed on one side of the threshing box 4, which facilitates the collection of bean grains and pods.
