Description

Technical Field

[0001] This utility model relates to the field of potato planting technology, specifically a potato cutting device for potato planting. Background Technology

[0002] As an important global food crop, potatoes often need to be cut into seed potatoes with buds during their cultivation to reduce planting costs and improve propagation efficiency. Traditional potato cutting methods mainly rely on manual operation, which has some drawbacks.

[0003] Manual cutting typically requires holding the potato down with one hand and using a knife to cut it into chunks with the other. Manual cutting is slow, and long-term operation can easily lead to worker fatigue. Furthermore, it is easy to injure one's hand during the cutting process. Some potato cutting devices have fixed blades, which are inconvenient to adjust for potatoes of different sizes. Utility Model Content

[0030] 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.

[0031] Example 1

[0032] Please see Figure 1-8In this embodiment of the present invention, a potato cutting device for planting includes a workbench 100, a positioning mechanism 200, a pushing mechanism 300, and a cross-cutting mechanism 400. The top surface of the workbench 100 has a horizontally oriented chute 120 and two vertically oriented chute 110s, which are symmetrical about the chute 120. A discharge chute 130 is located on the right side of the top surface of the workbench 100, and the top surface of the workbench 100 has a downward-facing angle at the edge of the discharge chute 130 to facilitate the falling of potato pieces. The positioning mechanism 200 includes two clamping plates 230. Two clamping plates 230 are symmetrically arranged on the top surface of the workbench 100. A connecting plate 240 is fixedly connected to the bottom surface of each clamping plate 230. The two connecting plates 240 are slidably connected to two sliding grooves 110. The pushing mechanism 300 includes a lead screw 310 and a stepper motor 320 installed on the bottom surface of the workbench 100. The motor shaft of the stepper motor 320 is drively connected to one end of the lead screw 310. A connecting plate 340 is screwed onto the outer wall of the lead screw 310. The connecting plate 340 is slidably connected to the sliding groove 120. A push plate 330 is fixedly connected to the top surface of the connecting plate 340. The push plate 330 is located at the workbench 100. On the top surface of the workbench 100, a cross-cutting mechanism 400 is positioned near the material dropper 130. The cross-cutting mechanism 400 includes a gantry frame 410, the bottom surface of which is fixedly connected to the top surface of the workbench 100. Two electric telescopic rods 420 are fixedly connected to the inner top surface of the gantry frame 410. A top plate 431 is fixedly connected to the bottom surface of the electric telescopic rods 420. A vertical cutter 430 is installed on the bottom surface of the top plate 431. Two horizontal slots 4311 are opened on the top surface of the top plate 431, and a horizontal cutter 440 is inserted into each of the two slots 4311. The top surfaces of the two horizontal cutters 440 are fixedly connected to a fixed... The bottom surface of the plate 441 is attached to the top surface of the top plate 431. A connecting frame 450 is slidably connected between two electric telescopic rods 420. Two connecting rods 451 and one electric telescopic rod 452 are fixedly connected to the bottom surface of the connecting frame 450. The bottom end of the electric telescopic rod 452 is fixedly connected to the top surface of the plate 441. The bottom ends of the two connecting rods 451 are fixedly connected to the top surface of the top plate 431, so that the horizontal cutter 440 will descend as the vertical cutter 430 descends. A collection frame 500 is set on the bottom surface of the workbench 100 directly below the material drop chute 130 to collect the potatoes cut into pieces.

[0033] Specifically, in use, the potato seed is placed between two clamping plates 230, and the two clamping plates 230 are controlled to move closer together to restrict the rolling of the potato. The stepper motor 320 is started, causing the lead screw 310 to rotate, which causes the connecting plate 340 to drive the push plate 330 to move along the slide groove 120, pushing the potato towards the cross-cutting mechanism 400. The electric telescopic rod 452 is in the extended state by default, so that the two horizontal cutters 440 and the vertical cutter 430 are brought together to form a cross shape. The two electric telescopic rods 420 are controlled to extend, causing the horizontal cutter 440 and the vertical cutter 430 to descend and cut the potato. According to the size of the potato, the push plate 330 continues to push the potato and causes the cross-cutting mechanism 400 to cut it again, cutting the potato into at least four pieces. After the cutting is completed, the push plate 330 controls the connecting plate 340 to continue sliding along the chute 120, pushing the potato pieces from the discharge chute 130 into the collection frame 500 below. When the potato seed is small and does not need to be cut into four pieces at once, the electric telescopic rod 452 is controlled to retract, driving the two horizontal cutters 440 to move upward. At this time, when the electric telescopic rod 420 extends downward to perform the cutting operation, only the vertical cutter 430 cuts the potato seed, cutting the potato seed into two pieces.

[0034] like Figure 3 As shown, in this embodiment, the positioning mechanism 200 includes a lead screw 210 and a stepper motor 220. The lead screw 210 is a bidirectional lead screw and is installed on the bottom surface of the worktable 100. The motor shaft of the stepper motor 220 is driven by one end of the lead screw 210. The bottoms of the two connecting plates 240 are screwed to the outer wall of the lead screw 210.

[0035] In this embodiment, in the initial state, the two clamping plates 230 are farthest apart. After the potato seed is placed between the two clamping plates 230, the stepper motor 220 is started. The stepper motor 220 drives the lead screw 210 to bring the two connecting plates 240 closer to each other, thereby restricting the position of the potato seed by the two clamping plates 230.

[0036] like Figure 2-3 As shown, in this embodiment, the clamping plate 230 includes a long plate 231 and a short plate 232. The long plate 231 and the short plate 232 are fixedly connected by a U-shaped rod 233. The top surfaces of the two connecting plates 240 are fixedly connected to the bottom surfaces of the two long plates 231 respectively. The top surface of the workbench 100 is vertically provided with a cutting groove 140. The cutting groove 140 and the sliding groove 120 intersect each other. The position of the cutting groove 140 corresponds to the position of the vertical cutter 430. There is a certain gap between the long plate 231 and the clamping plate 230. The position of the cutting groove 140 is located at this gap.

[0037] In practice, after pushing the potato seed to be cut into the gap between the long plate 231 and the short plate 232, the cross-cutting mechanism 400 is activated to cut it. The vertical cutter 430 is aligned with the blade groove 140, and the horizontal cutter 440 is aligned with the slide groove 120. The disconnected connection between the long plate 231 and the short plate 232 does not affect the descent of the vertical cutter 430, allowing the vertical cutter 430 to cut smoothly to the bottom.

[0038] Example 2

[0039] Based on Embodiment 1, in order to compensate for the fact that in Embodiment 1, when the vertical cutter 430 and the horizontal cutter 440 move upward after cutting the potato, the potato pieces will stick to the blade wall and affect the next cut.

[0040] like Figure 5-6 and Figure 8 As shown, in this embodiment, two circular holes 4312 are symmetrically opened on the top surface of the top plate 431. The cross-cutting mechanism 400 also includes an anti-sticking unit 460, which includes a scraper 461. A cross-shaped groove 462 is opened through the top surface of the scraper 461. The cross-shaped groove 462 is adapted to the size of the vertical cutter 430 and the horizontal cutter 440. Two round rods 463 are fixedly connected to the top surface of the scraper 461. The two round rods 463 are slidably inserted into the two circular holes 4312 respectively. A limit block is provided at the top of the round rods 463. A return spring 464 is sleeved on the outer wall of each of the two round rods 463. The two ends of the return spring 464 abut against the top surface of the scraper 461 and the bottom surface of the top plate 431 respectively.

[0041] In practice, under the elastic force of the round rod 463, the scraper 461 extends downward by default, positioned at the tip of the vertical cutter 430 and the horizontal cutter 440 to prevent accidental injury to workers. After the two clamping plates 230 clamp and restrict the potatoes, the electric telescopic rod 420 drives the top plate 431 to descend. During descent, the bottom surface of the scraper 461 first contacts the top surface of the two clamping plates 230. As the top plate 431 continues to descend, it slides downward along the round rod 463, compressing the return spring 464. When the vertical cutter 430 and the horizontal cutter 440 have completely passed through the cross-shaped groove 462 and cut the potato into chunks, when the electric telescopic rod 420 moves the vertical cutter 430 and the horizontal cutter 440 upward, the scraper 461 will remain stationary under the elastic force of the return spring 464, so that the scraper 461 can act as a scraper to intercept the potato chunks attached to the blade wall. Only when the top plate 431 moves to the point where its top surface abuts against the limiting block of the round rod 463 will the scraper 461 move upward and stop at the blade tip position.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
