[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 10 As shown, the present invention provides a bean thresher, which can replace manual operation to separate the shell and grain of seeds of various legume crops including soybeans, broad beans, mung beans, sesame, rapeseed, etc., and has high efficiency in shell-grain separation and less residual impurities in the seeds. Specifically:

[0040] The bean beating machine comprises a housing 1 and a feeding hopper 2 arranged on the housing 1, the feeding hopper 2 is sequentially connected with a bean beating assembly, a lifting mechanism 9 and a grain screening mechanism 3, and the grain screening mechanism 3 is connected with a first discharge port 10 and a second discharge port 11. The housing 1 serves as an overall frame, and the remaining components are arranged on it.

[0041] The unpeeled seeds enter from the feed hopper 2, and the shells and seeds are peeled off by the bean beating assembly. Then, the loose shells and seeds are transported to a high place by the lifting mechanism 9, and finally the shells and seeds are separated by the screening mechanism 3. The separated seeds and shells enter the corresponding first discharge port 10 and second discharge port 11 respectively, completing the seed collection work.

[0042] The bean bean beating assembly includes a first conveyor belt 4 and a second conveyor belt 5 which are arranged up and down. The material falls from the conveying end of the first conveyor belt 4 to the conveying starting end of the second conveyor belt 5. A material shifting device 6 is arranged above the first conveyor belt 4 and the second conveyor belt 5. A material pressing device 7 and a material cutting device 8 are also arranged in sequence at the conveying front end of the first conveyor belt 4.

[0043] The material-dispensing device 6 comprises a whip shaft frame 601 mounted on the first conveyor belt 4 and the second conveyor belt 5, on which a plurality of whip shafts 602 are arranged to roll perpendicularly to the conveying direction, and a plurality of rubber whips 603 are arranged in an annular array on the shaft wall of the whip shaft 602, and adjacent whip shafts 602 are connected by a traction belt 604, and the whip shaft 602 on one side is pulled by a pulley mechanism 605, and the pulley mechanism 605 is driven to rotate by a first motor 606. The rubber whips 603 act on the upper surfaces of the first conveyor belt 4 and the second conveyor belt 5.

[0044] Since the pulley mechanism 605 is a common transmission mechanism and is not the focus of the design of the present invention, it will not be described in detail here.

[0045] In the embodiment of the present invention, the whip shaft 602 and the rubber whip 603 are integrated as a whole, and a plurality of rubber whips 603 surround the whip shaft 602 to form a whip ring, and a plurality of such whip rings are arranged on the whip shaft 602, so as to increase the contact area with the seeds.

[0046] The pressing device 7 includes a pressing shaft support 701 arranged on the first conveyor belt 4, and a plurality of pressing shafts 702 are rollingly arranged on the pressing shaft support 701 for rolling and pressing the materials conveyed on the first conveyor belt 4. When the materials pass between the pressing shafts 702 and the first conveyor belt 4, the friction between the materials and the surfaces of the pressing shafts 702 causes the pressing shafts 702 to rotate and press the materials, thereby promoting the separation of the material shell and the seeds.

[0047] The cutting device 8 includes a gantry bracket 801 arranged above the first conveyor belt 4, and a push cylinder 802 is vertically arranged on the gantry bracket 801. The lower end of the push rod 803 of the push cylinder 802 is provided with a sickle 804 that spans the first conveyor belt 4. Sickle pads 805 flush with the surface of the first conveyor belt 4 are also provided on both sides of the first conveyor belt 4, and the sickle 804 and the sickle pad 805 cooperate with each other.

[0048] The up and down movement of the push rod 803 of the push cylinder 802 allows the sickle 804 to cut the materials transported by the first conveyor belt 4, and the sickle 804 may fall on the sickle pad 805 when it descends.

[0049] The material lifting mechanism 9 includes a conveying platform 901, and the conveying platform 901 includes a crawler belt 902 and a power assembly 905 for driving the crawler belt 902 for transmission. The power assembly 905 is a common pulley assembly mechanism and will not be described in detail here.

[0050] The middle section of the crawler 902 is provided with a guide wheel 903 for changing the conveying angle of the crawler 902, and the guide wheel 903 acts on the upper surface of the crawler 902. The upper surface of the crawler 902 is perpendicular to the conveying direction of the crawler 902 and is also provided with a plurality of railings 904 perpendicular to the surface of the crawler 902. The guide wheel 903 can divide the crawler 902 into two sections, front and rear, which is conducive to the smooth conveying of materials.

[0051] The particle screening mechanism 3 comprises an inner circular screen 301 and an outer circular screen 302 , and the inner circular screen 301 is embedded inside the outer circular screen 302 .

[0052] The inner circular sieve 301 and the outer circular sieve 302 both include a circular sieve wall 303 and a sieve bottom plate 309, and a plurality of partition plates 304 are arranged at equal intervals on the sieve bottom plate 309. The partition plates 304 of the inner circular sieve 301 and the outer circular sieve 302 are cross-arranged to form a plurality of leakage holes 305. By adjusting the relative angle of the partition plates 304 of the inner circular sieve 301 and the outer circular sieve 302, the size of the leakage holes 305 can be adjusted, thereby adjusting the aperture size of the leakage holes 305 according to the size of the seeds to be processed. A set of equipment is suitable for processing a variety of seeds, reducing the processing cost and improving the seed processing efficiency.

[0053] The inner circular screen 301 is driven by the first power mechanism 306 to rotate relative to the outer circular screen 302. Specifically:

[0054] The first power mechanism 306 includes a motor bracket 310 installed on the outer circular screen 302, and a second motor 311 is vertically installed on the motor bracket 310. The output shaft of the second motor 311 is connected to a gear 312, and the inner side wall of the inner circular screen 301 is provided with a circle of racks 313 that mesh with the gear 312.

[0055] When the second motor 311 is started, the second motor 311 drives the gear 312 to rotate, so that the inner circular screen 301 where the rack 313 meshing with the gear 312 is located rotates relative to the outer circular screen 302, and the angles of the partition plates 304 on the inner circular screen 301 and the outer circular screen 302 change, and the corresponding leakage holes 305 also change accordingly.

[0056] The outer circular screen 302 is driven to swing by the second power mechanism 307. Specifically:

[0057] The second power mechanism 307 includes a crankshaft 314 and a swing motor 315 . The crankshaft 314 is installed on the side wall of the outer circular screen 302 . The output shaft of the swing motor 315 is connected to the crankshaft 314 via a coupling 316 . The swing motor 315 is fixedly installed on the housing 1 .

[0058] When the swing motor 315 is working, the crankshaft 314 will drive the outer circular screen 302 and the inner circular screen 301 therein to swing and vibrate synchronously.

[0059] The outer circular screen 302 can be driven to flip sideways by the third power mechanism 308. Specifically:

[0060] The third power mechanism 308 includes a lifting rod 319 and a lifting motor 317 for lifting the lifting rod 319. The lifting rod 319 is suspended above the outer circular screen 302 and deviates from the diameter side of the outer circular screen 302. Spring connecting sleeves 321 are installed on both sides of the outer circular screen 302. The two ends of the lifting rod 319 are connected to the corresponding spring connecting sleeves 321 through springs 320. The lifting motor 317 is connected to the lifting rod 319 through a traction rope 318, and the lifting motor 317 is fixedly installed on the shell 1.

[0061] When the lifting motor 317 is working, the traction rope 318 can be wound around the motor shaft to lift the lifting rod 319. The lifting rod 319 uses the spring 320 to pull up one side of the outer circular screen 302, so that the waste inside the outer circular screen 302 can be poured out.

[0062] The first discharge port 10 is arranged directly below the outer circular screen 302, and the second discharge port 11 is arranged on one side of the outer circular screen 302 for receiving waste materials after the outer circular screen 302 is turned over. A blower 12 is arranged on one side of the housing 1 facing the second discharge port 11.

[0063] The working principle of the device of the present invention is as follows:

[0064] The size of the leakage hole 305 of the particle screening mechanism 3 is adjusted according to the particle size of the crop seeds to be processed.

[0065] The dried bean pods are put into the bean thresher from the feeding hopper 2. The dried bean pods enter the pressing device 7 from the input end of the first conveyor belt 4. The piles of bean pods are initially flattened by the pressing action of the pressing shaft 702 of the pressing device 7.

[0066] The flattened bean pods are chopped into sections when passing through the cutting device 8.

[0067] The bean pods are further transported along the first conveyor belt 4, and the rubber whip 603 of the material-dividing device 6 continuously whips the bean pods passing thereunder during the rotation process, so that the beans in the bean pods are separated from the bean pod shells.

[0068] When the bean pods move to the conveying end of the first conveyor belt 4, they will fall to the conveying starting end of the second conveyor belt 5 below, which has a good effect of turning the bean pods over. After that, the bean pods are whipped by the rubber whip 603 of the material-dividing device 6 again on the second conveyor belt 5, which improves the uniformity of bean bean bean beating and fully separates the beans and bean shells in the bean pods.

[0069] The bean pod shells and beans transported to the conveying end of the second conveyor belt 5 are transported to a high place by the lifting mechanism 9 and fall into the particle screening mechanism 3. The second power mechanism 307 is started to shake the inner circular screen 301 and the outer circular screen 302 to separate the bean pod shells and fine dust in the beans. This part of the debris is blown into the second discharge port 11 under the action of the blower 12, and the peeled beans enter the first discharge port 10 from the leakage hole 305 for centralized collection.

[0070] Finally, the third power mechanism 308 is started to change the inner circular screen 301 and the outer circular screen 302 from a horizontal state to a flipped state, so that the bean pod shells fall out of the second discharge port 11.

[0071] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
