Description

Technical Field

[0001] This utility model relates to the field of vegetable transplanting, and in particular to a double-row adjustable-distance vegetable transplanter. Background Technology

[0002] Vegetable transplanters are a type of machinery widely used in modern agricultural production. They can replace manual labor in planting vegetable seedlings, significantly improving planting efficiency and automation.

[0003] To further improve efficiency, multi-row (such as double-row) vegetable transplanters have emerged on the market, capable of planting multiple rows at once. However, in actual agronomic practice, different vegetable varieties or different field sizes have different requirements for planting row spacing.

[0004] In existing double-row or multi-row vegetable transplanters, the multiple planting units (i.e., transplanting mechanisms) are typically fixedly welded or rigidly connected to the crossbeams of the frame by bolts. This design results in a fixed row spacing between the planting units that cannot be changed.

[0005] This fixed row spacing structure makes it impossible for the same transplanter to flexibly adapt to planting tasks with different agronomic requirements. For example, after planting crop A, it cannot be used for crop B, which requires different row spacing. This results in poor equipment applicability and weak versatility. Farmers may need to purchase multiple machines of different specifications, which increases production costs. Therefore, this utility model proposes a double-row adjustable spacing vegetable transplanter to solve the shortcomings of the existing technology. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a double-row adjustable spacing vegetable transplanter, which aims to improve the problem that some existing vegetable transplanters have fixed planting row spacing, resulting in an inability to flexibly adapt to land of different widths and limited applicability.

[0007] This utility model provides a double-row adjustable spacing vegetable transplanter, including: a frame, on which a cross column is fixedly connected; and an adjustment mechanism that is slidably fitted onto the cross column.

[0008] The distance adjustment mechanism includes a sliding base plate, and the bottom of the sliding base plate is fixedly connected to a pressure cone, a chute, and a soil-aggregating sheet.

[0009] Furthermore, the adjusting mechanism is also equipped with a fixing component, which includes a support shaft vertically mounted on the sliding base plate. The top of the support shaft is rotatably connected to a lower pressure head that is an eccentric circle. A rubber block is provided on the sliding base plate, which is located below the lower pressure head and faces the horizontal column. When the lower pressure head rotates, its eccentric part presses down on the rubber block, so that the rubber block is fastened to the outer wall of the horizontal column, thus realizing the reliable fixing of the adjusting mechanism on the horizontal column.

[0010] Preferably, a pressure cone, a chute, and a soil-aggregating sheet are sequentially fixedly connected to the bottom surface of the sliding base plate along its forward and backward movement direction. This layout ensures that during transplanting, the pressure cone first presses the soil into the hole, then the chute guides the seedling, and finally the soil-aggregating sheet covers the soil, making the operation process smooth.

[0011] Preferably, a handle is fixedly connected to the rear end of the frame, which is used to facilitate the operator to push the frame forward.

[0012] Preferably, the handle and the soil-aggregating sheet are connected by a linkage mechanism. This structure allows the operator to push the handle down during the process, which in turn drives the soil-aggregating sheet to flip upwards, thus conveniently completing the soil-covering operation.

[0013] Preferably, the crossbar is a non-rotating fixed column, with wheels rotatably connected to its left and right ends via bearings. The wheels rotate only around the fixed crossbar, ensuring the reference stability of the adjusting mechanism when sliding and adjusting the distance on the crossbar.

[0014] Preferably, a double-row adjustable-space vegetable transplanter further includes a sliding mechanism. The sliding mechanism includes a front frame and a rear frame that are horizontally fixed along the front-rear direction of the frame, and a storage frame is slidably connected between the front frame and the rear frame along their length direction. The storage frame is used to hold vegetables.

[0015] Preferably, a buffer plate is fixedly connected to the inner wall of the rear frame facing the front frame, and a spring is elastically connected between the buffer plate and the inner wall of the rear frame. When the storage frame slides towards the rear frame, the spring and the buffer plate provide effective elastic cushioning to prevent impact.

[0016] Preferably, the chute has a hollow U-shaped groove structure. The upper end of the chute is used to receive vegetables, while the lower end opens towards the ground to precisely guide the vegetables into the pit formed by the downward pressure cone on the ground.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of fixed row spacing, inability to adapt to different widths of land, and poor applicability of existing vegetable transplanters by setting up an adjustable spacing mechanism that can slide along the horizontal column and using a fixed component that presses the rubber block with an eccentric circular pressure head for locking. It achieves the technical effects of flexible and fast row spacing adjustment, stable and reliable locking, and enhanced land adaptability.

[0018] 2. This utility model solves the problem that the original transplanter required manual handling of vegetables, which easily led to damage during operation, by setting up a storage frame that can slide between the front and rear frames and using a sliding mechanism with springs and buffer plates for cushioning. It achieves the technical effect of automatically storing vegetables, avoiding impact damage, and effectively protecting seedlings.

[0019] 3. This utility model integrates the pressure cone, the chute, and the soil-gathering plate on an adjustable sliding base plate, and connects the handle and the soil-gathering plate through a linkage mechanism. This solves the problems of traditional transplanters having a scattered structure, single function, and complex operation, and achieves the technical effects of compact structure, high functional integration, simple soil covering operation, and improved work efficiency.

Detailed Implementation

[0022] 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.

[0023] Example: Reference Figures 1 to 4 This utility model provides a double-row adjustable spacing vegetable transplanter, which aims to solve the problem that the fixed row spacing of existing vegetable transplanters makes it impossible to flexibly adapt to land of different widths and limits their applicability.

[0024] like Figure 1As shown, it includes a frame 1, on which a cross column 4 is fixedly connected. The frame 1 serves as the mounting base for the entire device, and the cross column 4 is used to support and slide in conjunction with the adjusting mechanism 2.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The adjusting mechanism 2 is slidably mounted on the cross column 4. The adjusting mechanism 2 includes a sliding base plate 21, and the bottom of the sliding base plate 21 is fixedly connected to a pressing cone 22, a groove 23, and a soil-gathering sheet 24 for planting operations. To achieve flexible adjustment and reliable fixation of the adjusting mechanism 2 on the cross column 4, a fixing component 25 is also provided on the adjusting mechanism 2. The fixing component 25 includes a support shaft 252 vertically mounted on the sliding base plate 21. The top of the support shaft 252 is rotatably connected to a pressing head 251, which is an eccentric circle. A rubber block 253 is also provided on the sliding base plate 21. The rubber block 253 is located below the pressing head 251 and faces the cross column 4. When the pressing head 251 rotates, its eccentric part presses down on the rubber block 253 to fasten it to the outer wall of the cross column 4, thereby completing the locking of the adjusting mechanism 2 at any position on the cross column 4.

[0026] Reference Figure 1 and Figure 4 The sliding mechanism 3 is mounted on the frame 1. The sliding mechanism 3 includes a front frame 31 and a rear frame 32 that are horizontally fixed along the front-rear direction of the frame 1. A storage frame 35 for accommodating vegetables is slidably connected between the front frame 31 and the rear frame 32 along their length. To prevent the storage frame 35 from experiencing severe impact during sliding, a buffer plate 34 is fixedly connected to the inner wall of the rear frame 32 facing the front frame 31, and a spring 33 is elastically connected between the buffer plate 34 and the inner wall of the rear frame 32.

[0027] In the assembled state, the storage box 35 can slide freely back and forth within the stroke defined by the front frame 31 and the rear frame 32. This sliding storage box 35 structure with spring 33 cushioning ensures that when the frame 1 is moving forward or stopping, the storage box 35 slides by inertia, and when it impacts the rear frame 32, it is effectively cushioned by the spring 33 and the buffer plate 34, thereby avoiding damage to the vegetables inside the storage box 35 caused by impact or manual handling.

[0028] Reference Figure 2 On the bottom surface of the sliding base plate 21, a pressing cone 22, a chute 23, and a soil-aggregating sheet 24 are fixedly connected in sequence along its front-to-back movement direction. The pressing cone 22 is located at the foremost end to press out the pit first, the chute 23 follows behind to guide the seedling, and the soil-aggregating sheet 24 is located at the rear end to cover the soil. Reference Figure 1A handle 6 is fixedly connected to the rear end of the frame 1, and the handle 6 is connected to the soil-aggregating sheet 24 through a linkage mechanism. The structure allows the operator to drive the soil-aggregating sheet 24 to flip upward when pressing down the handle 6 to perform the soil covering operation. The crossbar 4 is fixedly connected to the frame 1 in a non-rotational manner, and the left and right ends of the crossbar 4 are rotatably connected to wheels 5 through bearings. The wheels 5 rotate only around the fixed crossbar 4. Reference Figure 2 The chute 23 is specifically configured as a hollow U-shaped chute structure, with its upper end forming an opening to facilitate receiving vegetables, and its lower end opening precisely facing the pit position formed on the ground by the pressing cone 22.

[0029] The implementation principle of this application embodiment is as follows: When it is necessary to adjust the row spacing, the operator rotates the lower pressure head 251 of the fixing component 25. Since the lower pressure head 251 is an eccentric circle, its rotation causes its eccentric part to stop pressing down on the rubber block 253. The pressing force of the rubber block 253 on the horizontal column 4 is eliminated. At this time, the sliding base plate 21 of the spacing adjustment mechanism 2 is slidably fitted onto the horizontal column 4. The operator can push the sliding base plate 21 to slide along the outer wall of the horizontal column 4 to the predetermined position. Then, the lower pressure head 251 is rotated in the opposite direction. Its eccentric part presses down on the rubber block 253. After being pressed, the rubber block 253 is fastened to the outer wall of the horizontal column 4, thereby completing the quick locking of the spacing adjustment mechanism 2.

[0030] During transplanting, the operator pushes the handle 6, and the frame 1 moves forward under the rolling of the wheels 5. The adjusting mechanism 2, which is mounted on the crossbar 4, moves accordingly. The pressing cone 22, which is fixed to the bottom of the sliding base plate 21, first presses into the soil to form a pit. As the frame 1 continues to move forward, the hollow U-shaped groove structure chute 23 moves above the pit, and the vegetables slide into the pit from the chute 23. Then the operator presses down the handle 6, and the linkage mechanism between the handle 6 and the soil-gathering plate 24 drives the soil-gathering plate 24 to flip upward to gather soil and cover the vegetables, thus completing the transplanting.

[0031] During the movement of the whole machine, the storage box 35 in the sliding mechanism 3 slides along its length between the front frame 31 and the rear frame 32 due to inertia. When the frame 1 moves forward, the storage box 35 slides to the rear frame 32 and impacts the buffer plate 34 on the inner side of the rear frame 32. The buffer is achieved by the spring 33 behind the buffer plate 34. When the frame 1 stops or tilts, the storage box 35 slides to the front frame 31. This automatic sliding and buffering structure avoids damage to vegetables caused by manual handling.
