Description

Technical Field

[0001] The invention relates to the technical field of potato stock production, in particular to a device for grading potato stock specifications. Background Art

[0002] Potato original seeds are the seed potatoes initially produced by transplanting or cutting virus-free test tube seedlings. They are relatively small in size and are harvested from the fields. Farmers plant the original seeds, and what they harvest are the commercial potatoes sold on the market.

[0003] The original seeds are usually planted in a substrate cultivation method. When harvesting, the workers first pull out the rhizomes of the original seeds from the seedling pots, and then shake the original seeds from the rhizomes into the seedling pots. Then, the cultivation substrate in the seedling pots and the original seeds are poured into the screening machine for separation, and the original seeds are graded. However, in the process of pulling out and shaking off the original seeds, some rhizomes will remain or fall into the seedling pots, and because the screening machine used usually does not have the function of removing rhizomes, the rhizomes will accumulate on the screen of the screening machine, which will affect the normal screening. Therefore, workers are required to manually pick out the rhizomes before screening, or manually remove the rhizomes accumulated on the screen during the screening process.

[0004] A Chinese patent with patent announcement number CN212069446U discloses a potato stock seed specification grading device to solve the problem of low efficiency of potato stock seed grading in the prior art. The potato stock seed specification grading device includes a bracket, a buffer support is fixed on the top of the bracket, a tilted trough is fixed on the top of the buffer support, a vibrator is installed at the bottom of the trough, and a multi-stage screen with gradually decreasing mesh size is arranged in the trough from top to bottom, and a plurality of stock seed outlets corresponding to the multi-stage screen are arranged at one end of the trough that is tilted downward. The present invention can achieve efficient and rapid grading, and the grading speed is more than five times higher than that of traditional manual sorting, and the grading quality of the stock seed can be improved. Due to the separation and grading by machine vibration, the grading is directly bagged, which is convenient for storage and transportation.

[0005] Disadvantages of the prior art: Since the equipment does not have the function of removing rhizomes, workers are required to manually pick out the rhizomes remaining or falling in the seedling pots before screening, or manually remove the rhizomes during the screening process. The method of manually picking out the rhizomes before screening will not only reduce the overall screening efficiency, but also increase the labor intensity of the workers. The method of manually removing the rhizomes during the screening process will occupy manpower for a long time, and will also increase the labor intensity of the workers, and also has certain safety hazards.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0029] Embodiment 1: A potato seed specification grading device, such as Figure 1-Figure 4As shown, it includes a screening frame 1, a large sieve plate 101, a small sieve plate 102, a guide cylinder 103, a motor 104, a driving shaft 105, a flip plate 106, a debris removal plate 107, a No. 1 spring 108, a debris removal hook 109 and a transmission component. The large sieve plate 101 and the small sieve plate 102 are rotatably connected on the inner wall of the screening frame 1. The large sieve plate 101 is located on the upper side of the small sieve plate 102, and the aperture of the sieve hole of the large sieve plate 101 is larger than the aperture of the sieve hole of the small sieve plate 102. The large sieve plate 101 and the small sieve plate 102 are slidably connected with the guide cylinder 103 together. The guide cylinder 103 is used to drive the large sieve plate 101 and the small sieve plate 102 to rotate synchronously, and the large sieve plate 101 and the small sieve plate 102 can slide along the axial direction of the guide cylinder 103. A driving shaft 105 is fixedly connected in the guide cylinder 103, and a motor 104 is fixedly connected to the lower end of the driving shaft 105. The motor 10 4 is used to drive the driving shaft 105 to rotate. The guide cylinder 103 is rotatably connected with a flip plate 106 through a transmission assembly, and the flip plate 106 can only rotate in one direction on a vertical plane. A dust collecting plate 107 is slidably connected to the flip plate 106 in the vertical direction. A No. 1 spring 108 is sleeved on the guide rod of the dust collecting plate 107. When the dust collecting plate 107 slides in the direction close to the flip plate 106, the No. 1 spring 108 will be compressed. Five dust collecting hooks 109 are fixedly connected at an end of the dust collecting plate 107 away from the flip plate 106 at equal intervals. The dust collecting hooks 109 are used to collect rhizomes. The driving shaft 105 drives the flip plate 106 to rotate horizontally through the transmission assembly to collect rhizomes, and the rotation direction is opposite to the rotation direction of the guide cylinder 103, and the transmission assembly can drive the flip plate 106 to rotate vertically to throw out the rhizomes on the dust collecting hooks 109.

[0030] When the motor 104 drives the driving shaft 105 to rotate forward, the guide cylinder 103 will drive the large sieve plate 101 and the small sieve plate 102 to rotate forward synchronously, and the guide cylinder 103 will drive the flip plate 106 to reverse horizontally through the guide component, and the worker will pour the matrix and original seeds in the seedling pot onto the large sieve plate 101, and the original seeds and matrix with smaller particle sizes will pass through the sieve holes of the large sieve plate 101 and fall down onto the small sieve plate 102, and the matrix will continue to fall downward through the small sieve plate 102, so that the large original seeds with qualified particle sizes will remain on the large sieve plate 101, the small original seeds with qualified particle sizes will remain on the small sieve plate 102, and the matrix and the original seeds with unqualified particle sizes will fall downward, so as to separate the qualified original seeds from the matrix, and classify the qualified original seeds according to the particle size; the impurity removal hook 109 will contact the matrix and rhizomes during the rotation of the flip plate 106, and the original seeds and the matrix will pass through the impurity removal hooks 109 , and the rhizome will be blocked by the weeding hook 109 due to its long length, and the rhizome moves with the weeding hook 109, so that the rhizome is separated from the matrix and the original seed. When the flip plate 106 is about to rotate horizontally for one circle, the transmission component will drive the flip plate 106 to rotate vertically by about 220 degrees, so that the weeding hook 109 can throw the collected rhizome out of the screening frame 1 during the rotation process, thereby avoiding a large amount of rhizome accumulation on the large sieve plate 101 and affecting the screening of the original seed. When the flip plate 106 continues to rotate horizontally, the transmission component will drive the flip plate 106 to rotate vertically by about 140 degrees, so that the weeding hook 109 rotates to a state perpendicular to the large sieve plate 101 to continue collecting rhizomes; and because the matrix and the original seed will be piled up together when pouring them onto the large sieve plate 101, the weeding hook 109 can spread out the accumulated matrix and the original seed during the rotation process for better screening.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the transmission assembly includes a gear ring 2, a processing table 201, a flip seat 202, a flip shaft 203, a bevel gear 204, a fixing frame 205, a driven gear 206, a tooth plate 207 and a driving gear 208. The upper end of the guide cylinder 103 is rotatably connected to the gear ring 2. The gear ring 2 is a ring shape with teeth on the inner wall. The flip seat 202 is fixedly connected to the eccentric position of the upper end of the gear ring 2. The flip seat 202 is rotatably connected to the flip shaft 203. The flip shaft 20 3 is fixedly connected to the flip plate 106, a bevel gear 204 is fixedly connected to the flip shaft 203, a processing table 201 is placed on the ground, the processing table 201 consists of a table top, four legs and an I-shaped bracket, the table top is fixedly connected to the top of the four legs, the I-shaped bracket is fixedly connected to the four legs, the screening frame 1 is installed on the processing table 201, the motor 104 is fixedly connected to the lower end of the I-shaped bracket, and the output shaft of the motor 104 faces upward, and the lower end of the driving shaft 105 passes through the I-shaped bracket. The shaped bracket is connected to the output shaft of the motor 104. A fixing frame 205 is fixedly connected to the lower end of the table of the processing table 201. A driven gear 206 is rotatably connected to the fixing frame 205. A driving gear 208 is fixedly connected to the driving shaft 105. The driven gear 206 is located between the driving gear 208 and the gear ring 2, and the driven gear 206, the driving gear 208 and the gear ring 2 are meshed at the same time, so that when the driving shaft 105 rotates, the gear ring 2 can be driven to rotate in the opposite direction. Two tooth plates 207 are fixedly connected to the fixing frame 205, and the tooth plates 207 cooperate with the bevel gear 204. During the rotation of the gear ring 2, the first tooth plate 207 will first drive the flip shaft 203 to rotate 220 degrees through the bevel gear 204, so that the impurity hook 109 can throw out the rhizomes. The second tooth plate 207 will drive the flip shaft 203 to rotate 140 degrees through the bevel gear 204, so that the impurity hook 109 rotates to a state perpendicular to the large sieve plate 101 to continue to collect rhizomes.

[0032] When the guide cylinder 103 rotates forward, it will drive the gear ring 2 to reverse through the driving gear 208 and the driven gear 206. The gear ring 2 drives the flip plate 106 to reverse synchronously through the flip seat 202 and the flip shaft 203. When the flip plate 106 is about to rotate horizontally for one circle, the bevel gear 204 is engaged with the first tooth plate 207. The tooth plate 207 will drive the flip shaft 203 to rotate about 220 degrees through the bevel gear 204, so that the impurity removal hook 109 can throw the rhizomes backwards, and then the bevel gear 204 is engaged with the second tooth plate 207. The second tooth plate 207 drives the flip shaft 203 to rotate about 140 degrees through the bevel gear 204, so that the impurity removal hook 109 is perpendicular to the large screen plate 101 to continue to collect rhizomes.

[0033] The turning shaft 203 can only rotate in one direction.

[0034] This prevents the de-impuring hook 109 from being reversed in the vertical direction due to the resistance of the matrix, original seed and rhizome, so that the de-impuring hook 109 can always remain in a vertical position with the large sieve plate 101 during the process of collecting rhizomes.

[0035] like Figure 4 and Figure 6 As shown, it also includes a support ring 3, a lower top block 301 and an upper top block 302 for driving the impurity removing plate 107 to shake. The support ring 3 is fixedly connected to the outer wall of the guide cylinder 103, and the support ring 3 is located above the large sieve plate 101. The support ring 3 is in the shape of a circular ring, and a plurality of lower top blocks 301 are fixedly connected to the top of the support ring 3 in a circular array. An upper top block 302 is fixedly connected to one end of the impurity removing plate 107 close to the support ring 3, and the lower top block 301 is squeezed together with the upper top block 302 to drive the impurity removing plate 107 to move upward.

[0036] When the gear ring 2 drives the turning seat 202 to rotate, the upper top block 302 on the cleaning plate 107 will contact the lower top block 301, and the lower top block 301 will squeeze the upper top block 302 upward, thereby driving the cleaning plate 107 and the cleaning hook 109 to move upward. When the cleaning plate 107 moves upward, the No. 1 spring 108 is compressed. When the lower top block 301 and the upper top block 302 are out of contact, the cleaning plate 107 is reset downward, thereby driving the cleaning hook 109 to shake up and down during the rotation process, so that the original seeds can pass through better between the cleaning hooks 109, and the accumulated matrix and original seeds can be better spread out.

[0037] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, it also includes a material control mechanism for automatically controlling the discharge of the original seed, the material control mechanism is connected to the driving shaft 105, and the material control mechanism includes a linkage frame 5, a third spring 501, an upper baffle 502, a lower baffle 503, a connecting shaft 504, a rotating disk 505, a material control gear 506, a lower convex plate 507, an upper convex plate 508 and a missing gear 509. The processing table 201 is slidably connected to the linkage frame 5 in the vertical direction. The linkage frame 5 consists of a support plate and two groups of guide rods on both sides. Each group of guide rods There are two, and the guide rods of the linkage frame 5 are sleeved with No. 3 springs 501. When the linkage frame 5 moves upward, the No. 3 springs 501 will be compressed. The lower end of one set of guide rods of the linkage frame 5 is fixedly connected to an upper baffle 502, and the lower end of the other set of guide rods is fixedly connected to a lower baffle 503. There are two upper and lower notches on the screening frame 1, and the bottom of the upper notch is consistent with the height of the large sieve plate 101, so that the original seeds on the large sieve plate 101 can flow out through the upper notch. The upper baffle 502 is located on the upper side. The bottom of the lower notch is at the same height as the small sieve plate 102, so that the original seeds on the small sieve plate 102 can flow out through the lower notch. The lower baffle plate 503 is located at the lower notch position, and the lower baffle plate 503 is used to prevent the original seeds from flowing out from the lower notch. The lower end of the table surface of the processing table 201 is fixedly connected with a connecting shaft 504, and a turntable 505 and a material control gear 506 are rotatably connected to the connecting shaft 504. The material control gear 506 is connected to the processing table 201. The wheel 506 is fixedly connected to the turntable 505, and the turntable 505 is located on the upper side of the material control gear 506. A lower convex plate 507 is fixedly connected to the upper end of the turntable 505, and an upper convex plate 508 is fixedly connected to the lower end of the linkage frame 5. The upper convex plate 508 passes downward from the table surface of the processing table 201. The lower convex plate 507 is used to squeeze the upper convex plate 508 upward to drive the upper baffle 502 and the lower baffle 503 to open. A missing gear 509 is fixedly connected to the driving shaft 105, and the missing gear 509 can engage with the material control gear 506 during rotation.

[0038] During the rotation of the driving shaft 105, the missing gear 509 will drive the material control gear 506 to rotate, and the material control gear 506 will drive the turntable 505 to rotate. Since the missing gear 509 has fewer teeth, the turntable 505 can only rotate one circle after the driving shaft 105 rotates for many circles, so as to avoid insufficient screening. During the rotation of the turntable 505, the lower convex plate 507 will squeeze the upper convex plate 508 upward, thereby driving the linkage frame 5 to move upward and compress the No. 3 spring 501. The linkage frame 5 will drive the upper baffle plate 502 and the lower baffle plate 503 to move upward, so that the original seeds on the large sieve plate 101 and the small sieve plate 102 can be discharged from the screening frame 1 to the outside. When the upper convex plate 508 and the lower convex plate 507 are out of contact, the No. 3 spring 501 pushes the linkage frame 5 to reset downward, so that the upper baffle plate 502 and the lower baffle plate 503 continue to block the discharge of the original seeds.

[0039] like Figure 2 and Figure 8 As shown, it also includes a collecting mechanism for removing and collecting roots and stems on the impurity removal hook 109, the collecting mechanism is connected to the screening frame 1, and the collecting mechanism includes a material receiving support plate 6, a material receiving box 601, a guide rod 602, a material receiving hook 603 and a guide plate 604. The outer wall of the screening frame 1 is fixedly connected to the material receiving support plate 6, the material receiving box 601 is fixedly connected to the material receiving support plate 6, and five guide rods 602 are fixedly connected to the material receiving box 601 at equal intervals. The guide rod 602 is L-shaped, and one end of the guide rod 602 extends above the screening frame 1, and the end is fixedly connected to the material receiving hook 60 3. The material receiving hook 603 is composed of two sections of rods, wherein one section of the rod fixedly connected to the end of the guide rod 602 is arc-shaped, used to cooperate with the revolution path of the weeding hook 109 to avoid jamming, and the other section of the rod is a straight rod, used to remove the rhizomes on the weeding hook 109. A guide plate 604 is fixedly connected to the material receiving box 601, and the guide plate 604 is used to receive the fallen rhizomes. The guide plate 604 is located at the lower side of the guide rod 602. The guide plate 604 and the guide rod 602 are both inclined, and the end connected to the material receiving box 601 is lower than the other end extending to the upper side of the screening frame 1.

[0040] During the first vertical rotation of the flip plate 106 by 220 degrees, the lower end of the cleaning hook 109 will rotate to the upper side of the material collecting hook 603, and the rhizomes will be thrown onto the guide rod 602, the material collecting hook 603 and the guide plate 604 under the action of inertia. Moreover, since the portion of the material collecting hook 603 fixed to the end of the guide rod 602 is arc-shaped, and the arc is concentric with the revolution path of the cleaning hook 109, the cleaning hook 109 will not collide with the material collecting hook 603 during its continued revolution, and each material collecting hook 603 is in contact with a cleaning hook 109, so that the material collecting hook 603 can remove the rhizomes hanging on the cleaning hook 109 during its continued horizontal revolution. The flip plate 106 will rotate 140 degrees in the vertical direction again when the cleaning hook 109 and the material collecting hook 603 are out of contact.

[0041] Embodiment 3: Based on embodiment 2, Figure 2 and Figure 3 As shown, it also includes a recovery mechanism for collecting the matrix, the recovery mechanism is connected to the driving shaft 105, the recovery mechanism includes a recovery frame 7, a discharge pipe 701, a discharge disk 702 and a discharge rod 703, the lower end of the screening frame 1 is fixedly connected to the recovery frame 7, the side wall of the recovery frame 7 is connected to the discharge pipe 701 for discharging the matrix, the inner wall of the recovery frame 7 is rotatably connected to the discharge disk 702, the discharge disk 702 is axially slidably connected to the guide cylinder 103, and the guide cylinder 103 can drive the discharge disk 702 to rotate, and a plurality of discharge rods 703 are fixedly connected to the top of the discharge disk 702 in an annular array, and the discharge rods 703 are used to provide thrust and guiding effects for the matrix.

[0042] The matrix screened by the small sieve plate 102 will fall onto the discharge tray 702. The guide cylinder 103 will drive the discharge tray 702 to rotate during rotation. The discharge rod 703 will push the matrix on the discharge tray 702 to rotate together, and the matrix will be discharged from the discharge pipe 701 under the action of centrifugal force.

[0043] like Figure 1 , Fig. 9 and Fig.10 As shown, it also includes a force block 8, a fixed disk 801, a shaking top block 802 and a No. 4 spring 803 for driving the screening frame 1 and the recycling frame 7 to shake. A plurality of force blocks 8 are fixedly connected in a circular array at the lower end of the discharge disk 702. The upper end of the I-shaped bracket of the processing table 201 is fixedly connected with a fixed disk 801. The driving shaft 105 passes through the middle of the fixed disk 801. Two shaking top blocks 802 are symmetrically fixedly connected to the upper end of the fixed disk 801. The shaking top block 802 is used to squeeze the force block 8 upward to drive the screening frame 1 and the recycling frame 7 to move upward. The screening frame 1 is slidably connected to the processing table 201 in the vertical direction, and the guide rod of the screening frame 1 is provided with a No. 4 spring 803 for buffering. When the screening frame 1 moves downward, the No. 4 spring 803 will be compressed.

[0044] During the rotation of the discharge tray 702, the shaking top block 802 will intermittently squeeze the force block 8 upwards, and the force block 8 will drive the recovery frame 7 and the screening frame 1 to move upwards through the discharge tray 702. When the shaking top block 802 and the force block 8 are out of contact, the recovery frame 7 and the screening frame 1 are reset downward, so that the recovery frame 7 and the screening frame 1 are driven to shake up and down under the action of the force block 8 and the shaking top block 802, thereby driving the large screen plate 101 and the small screen plate 102 to shake to improve the screening efficiency, and the screening frame 1 will drive the material receiving support plate 6 to shake, so that the roots and stems on the guide rod 602, the material receiving hook 603 and the guide plate 604 can move into the material receiving box 601.

[0045] like Figure 4 As shown, the debris removing hook 109 includes a guide tube 4, a hook claw 401 and a second spring 402. Five guide tubes 4 are fixedly connected to the lower end of the debris removing plate 107 at equal intervals. The guide tubes 4 are all connected with hook claws 401 in an axial sliding manner. The hook claw 401 is L-shaped, and a second spring 402 is installed in the guide tube 4. When the hook claw 401 slides toward the direction of the debris removing plate 107, the second spring will be compressed.

[0046] In order to avoid a hard collision between the large sieve plate 101 and the debris removal hook 109 during shaking, the debris removal hook 109 is set to a retractable structure so that the large sieve plate 101 can squeeze the hook claw 401 into the guide tube 4 when it is upward, and the No. 2 spring 402 can push the hook claw 401 to return downward when the large sieve plate 101 is reset downward.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
