[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A potato seed sorting machine includes a housing 1, a feed hopper 11 at the top of the housing 1, four casters 12 at the bottom of the housing 1, three screen plates 2 arranged sequentially along the height direction inside the housing 1, the three screen plates 2 respectively having a first screen hole 21, a second screen hole 22 and a third screen hole 23 with decreasing apertures, a U-shaped frame 24 at the top of the screen plate 2, a baffle 3 detachably installed on the U-shaped frame 24, a rotating shaft 4 fixedly installed on both sides of the three U-shaped frames 24, a sprocket 41 installed on the rotating shaft 4 on one side of the three U-shaped frames 24, the three sprockets 41 being connected by a chain 42, a drive mechanism 5 for driving one of the sprockets 41 to rotate clockwise and counterclockwise on one side of the housing 1, an auxiliary support mechanism 7 at the bottom of the housing 1, and three closed doors 25 connected to the screen plates 2 on one side of the housing 1.

[0027] This invention uses a drive mechanism 5 to drive the corresponding sprocket 41 to rotate clockwise and counterclockwise. The sprocket 41 drives the remaining two sprockets 41 to rotate synchronously via a chain 42. The three U-shaped frames 24 and the three sieve plates 2 rotate synchronously. The potato seed stock on the sieve plate 2 can roll left and right on the sieve plate 2. All potato seed stock can come into contact with the sieve plate 2 for screening, avoiding accumulation on the surface of the sieve plate 2, which would affect the screening of potato seed stock. This improves the screening effect of potato seed stock and also speeds up the screening efficiency of potato seed stock.

[0028] It is worth noting that the diameter of the sprocket 41 located in the middle is larger than that of the other two sprockets 41, which increases the contact area between the sprocket 41 and the chain 42.

[0029] The drive mechanism 5 includes a gear 51, a fixed base 52, a U-shaped frame 53, an electric cylinder 54, and a rack 55. The fixed base 52 is equipped with a height adjustment component 6. The gear 51 is mounted on a rotating shaft 4 at the lower end. The fixed base 52 is located on one side of the housing 1. The U-shaped frame 53 is mounted on the height adjustment component 6. The electric cylinder 54 is horizontally mounted inside the U-shaped frame 53. The rack 55 is mounted on the output shaft of the electric cylinder 54 and meshes with the gear 51.

[0030] The electric cylinder 54 drives the rack 55 to move back and forth, and the rack 55 drives the gear 51 to rotate clockwise and counterclockwise. The sprocket 41 drives the remaining two sprockets 41 to rotate synchronously through the chain 42, thereby realizing that the three screen plates 2 can rotate stably clockwise and counterclockwise synchronously.

[0031] The adjusting assembly 6 includes two dovetail blocks 61 and four fixing bolts 62. Both ends of the dovetail blocks 61 are provided with threaded holes. Two dovetail grooves 63 are provided on one side of the fixing seat 52. The dovetail blocks 61 are slidably disposed in the dovetail grooves 63. The two dovetail blocks 61 are fixedly connected to one side of the U-shaped frame 53. The fixing bolts 62 are screwed into the threaded holes. A crank handle 64 is provided on the bottom rotating shaft 4.

[0032] When power cannot be supplied to the equipment, first loosen the fixing bolt 62 to release the dovetail block 61 from its locked state. Then, allow the U-shaped frame 53 to slide downwards in the dovetail groove 63 through the dovetail block 61. Next, the rack 55 of the electric cylinder 54 disengages from the gear 51. Then, tighten the fixing bolt 62. One end of the fixing bolt 62 presses against the dovetail groove 63 to fix the position of the dovetail block 61. At this time, manually turn the crank handle 64 to drive the rotating shaft 4 to rotate. This method replaces the electric power transmission and can be used under different conditions, improving the equipment's performance.

[0033] The top of the U-shaped frame 53 is equipped with a first handle 65, which makes it convenient to adjust the vertical position of the U-shaped frame 53 when using the equipment.

[0034] The inner walls on both sides of the U-shaped frame 24 are provided with vertical sliding grooves 31. The bottom of the baffle 3 is provided with a magnetic layer, and the top of the sieve plate 2 is provided with an adsorption layer that cooperates with the magnetic layer. The two ends of the baffle 3 are respectively slidably set in the two vertical sliding grooves 31. The vertical sliding grooves 31 facilitate the installation and removal of the baffle 3. The magnetic layer and the adsorption layer can improve the positioning stability of the baffle 3 and prevent the potato seed from falling out accidentally due to excessive gap between the baffle 3 and the sieve plate 2.

[0035] A second handle 32 is provided on one side of the baffle 3, which makes it easy for workers to grip and disassemble the baffle 3.

[0036] The auxiliary support mechanism 7 includes four auxiliary support components, each including a pin 71, a support sleeve 72, a support rod 73, and a support block 74. The support sleeve 72 has several first positioning holes 75 along its height direction on one side, which cooperate with the pin 71. The support rod 73 has a second positioning hole 76 on its upper end that cooperates with the pin 71. There are mounting grooves at the four corners of the bottom of the housing. The support sleeve 72 is installed in the mounting grooves, the support rod 73 is slidably disposed in the support sleeve 72, and the support block 74 is disposed at the bottom of the support rod 73.

[0037] Since the ground at the potato seed harvesting site is mostly uneven, the support rod 73 can be pulled, and then the pin 71 can be inserted into a first positioning hole 75 on the support sleeve 72 and a second positioning hole 76 on the support rod 73 to lock the support rod 73. This allows the height of the corresponding corner of the box 1 to be adjusted so that the entire equipment can be kept level during operation.

[0038] Working principle: The equipment is moved to the work site by four casters 12. Then, the potato seed is poured into the box 1. The potato seed is then sorted through the first sieve hole 21, the second sieve hole 22 and the third sieve hole 23 on the surface of the three sieve plates 2 to sort the potato seed of different sizes. The auxiliary support mechanism 7 can keep the entire equipment in a horizontal state on uneven ground. After the equipment has sorted the potato seed, the closed door 25 is opened and the worker pulls the baffle 3 to remove it. Then, the sorted potato seed is taken out from the sieve plate 2, and the use of the equipment is completed.
