Description

Technical Field

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

[0002] Pressing down crop seedlings can increase soil compaction, maintain soil surface moisture, and prevent soil subsidence. This can achieve the effects of crushing the soil, conserving moisture, promoting seedling emergence, and increasing crop yield. It can also enhance the drought and frost resistance of seedlings and promote the secondary development of crop roots.

[0003] This paper analyzes the issue of improving peanut yield by pressing down peanut seedlings. During peanut growth, peanut seedlings develop stigmas, which must penetrate the soil to mature into peanut pods. Without disturbing the stigmas, there is a certain distance between them and the soil, affecting contact and thus yield. Therefore, to increase yield after the seedlings develop stigmas, manual pressing is often used to press them down to make contact with the soil. However, this method is labor-intensive and inefficient. Furthermore, existing pressing devices cannot control the pressure as manually, affecting the effectiveness of pressing. To address these issues, a suitable pressing device for crop cultivation is needed. Utility Model Content

[0025] For an example, please refer to... Figure 1-5 This utility model provides a technical solution:

[0026] A seedling pressing device for crop planting includes a mobile cart 1, a controller 2 connected to the end face of the mobile cart 1, an inertial telescopic structure 3 connected to the end face of the mobile cart 1, and an adjustable pressing plate structure 4 connected to the bottom of the inertial telescopic structure 3.

[0027] In this embodiment, reference Figure 1 , Figure 2 and Figure 3 The inertial telescopic structure 3 includes a connecting bracket 301, which is connected to the end face of the mobile trolley 1. A drive motor 302 is connected to the side wall of the connecting bracket 301 via a connecting seat. The drive end of the drive motor 302 is connected to a drive rod 303 via a coupling. Two sets of drive gears 304 are connected to the side wall of the drive rod 303. A driven gear 305 is meshed with the side wall of the drive gear 304.

A telescopic spring 312 is provided between the connecting block 309 and the limiting sleeve 311 and on the outer wall of the connecting slide rod 310.

[0028] Based on the above structure and the connection relationship of the above structure, the controller 2 controls the drive motor 302 to run. When the drive end of the drive motor 302 rotates, it sequentially drives the drive rod 303, drive gear 304, driven gear 305, rotating rod 306 and spiral cam 307 to rotate. When the spiral cam 307 rotates, the moving lever 308 drives the connecting block 309 and the connecting slide rod 310 to move upward. At the same time as the connecting slide rod 310 moves upward, the telescopic spring 312 is compressed. When the spiral cam 307 and the moving lever 308 disengage from each other, under the action of the telescopic spring 312, the moving pressure plate 409 in the adjustable pressure plate structure 4 at the bottom of the connecting slide rod 310 moves downward instantaneously.

When the drive rod 303 rotates, the telescopic spring 312 can be compressed.

[0031] In this embodiment, reference Figure 1 , Figure 4 and Figure 5 The adjustable pressure plate structure 4 includes a connecting housing 401, which is connected to the bottom of the connecting slide rod 310. A rotating screw 402 is connected to the side wall of the connecting housing 401. A rotating knob 403 is connected to one end of the rotating screw 402. A shaft retainer 404 is connected to the side wall of the connecting housing 401 and the outer wall of the rotating screw 402. A movable slide plate 405 is symmetrically connected to the side wall of the rotating screw 402 and the inner cavity of the connecting housing 401. A limiting slide rod 406 is symmetrically connected to the movable slide plate 405 and to both sides of the rotating screw 402. The two ends of the limiting slide rod 406 are connected to the side wall of the inner cavity of the connecting housing 401. A movable slider 407 is symmetrically connected to the side wall of the movable slide plate 405. A connecting slider 408 is connected to the movable slider 407. A movable pressure plate 409 is connected to the bottom of the connecting slider 408. A connecting slide rod 410 is connected to each of the four corners of the end face of the movable pressure plate 409.

[0032] Based on the above structure and the connection relationship of the above structure, by manually rotating the rotating screw 402, when the rotating screw 402 rotates, it drives the two sets of movable slide plates 405 to move in opposite directions on the side wall of the rotating screw 402. When the two sets of movable slide plates 405 move in opposite directions on the side wall of the rotating screw 402, the distance between the movable pressure plate 409 and the ground is adjusted by the movable slider 407 and the connecting slider 408.

[0033] Furthermore, the rotating lead screw 402 is connected to the side wall of the connecting housing 401 via a bearing seat. The rotating lead screw 402 is rotatably connected to the bearing seat, and the rotating lead screw 402 is threadedly connected to the movable slide plate 405. The rotating lead screw 402 is composed of a left-handed lead screw and a right-handed lead screw. The movable slide plate 405 has a connecting hole corresponding to the limiting slide rod 406. The limiting slide rod 406 is slidably connected to the connecting hole. The cross-sections of the movable slider 407 and the connecting slider 408 are both right-angled trapezoidal structures. The surfaces of the movable slider 407 and the connecting slider 408 that contact each other have interlocking grooves, and the movable slider 407 and the connecting slider 408 are slidably connected. The connecting housing 401 has a connecting hole corresponding to the connecting slide rod 410. The connecting slide rod 410 is slidably connected to the connecting hole. When the rotating lead screw 402 rotates, the height of the movable pressure plate 409 from the ground can be adjusted.

[0034] The working process of this utility model is as follows: When using the seedling pressing device for crop planting, the rotating screw 402 is manually rotated. When the rotating screw 402 rotates, it drives two sets of movable sliding plates 405 to move in opposite directions on the side wall of the rotating screw 402. As the two sets of movable sliding plates 405 move in opposite directions on the side wall of the rotating screw 402, the distance between the movable pressing plate 409 and the ground is adjusted by the movable slider 407 and the connecting slider 408, thereby adjusting the pressure of the movable pressing plate 409 on the ground when pressing the seedling.

[0035] The controller 2 controls the operation of the drive motor 302. When the drive end of the drive motor 302 rotates, it drives the drive rod 303 to rotate. The drive rod 303 drives the drive gear 304 to rotate. The drive gear 304 drives the driven gear 305 to rotate. The driven gear 305 drives the rotating rod 306 to rotate. The rotating rod 306 drives the spiral cam 307 to rotate. When the spiral cam 307 rotates, the moving lever 308 drives the connecting block 309 and the connecting slide rod 310 to move upward. At the same time as the connecting slide rod 310 moves upward, the telescopic spring 312 is compressed. When the spiral cam 307 and the moving lever 308 disengage, under the action of the telescopic spring 312, the movable pressure plate 409 in the adjustable pressure plate structure 4 at the bottom of the connecting slide rod 310 moves downward instantaneously, thereby performing the seedling pressing work of crops.
