Description

Technical Field

[0001] This utility model relates to the field of seedling transplanting technology, specifically to a seedling transplanting machine. Background Technology

[0002] The transplanter mainly consists of four parts: a seedling storage mechanism, a seedling clamping mechanism, a seedling delivery mechanism, and a seedling planting mechanism. The seedling storage mechanism is used to place seedling trays on which multiple seedlings are arranged in an array. The seedling clamping mechanism is used to clamp the seedlings on the seedling trays and transfer them to the seedling delivery mechanism. The seedling delivery mechanism is used to transport the seedlings to the seedling planting mechanism, which is used to insert the seedlings into the soil.

[0003] The seedling clamping mechanism uses a horizontally and vertically movable clamp to pick up seedlings from the seedling tray and place them onto the seedling delivery mechanism. However, as the number of times the clamp picks up seedlings from the seedling tray increases, the distance between the clamping positions increases, and the stability of the clamping position and the accuracy of the clamping position further decrease. In order to ensure the stability and accuracy of the clamp, the structure of the seedling clamping mechanism has become increasingly complex, and the control difficulty has become increasingly high. Utility Model Content

[0004] To address the technical problems of complex structure and high control difficulty in seedling clamping mechanisms, this invention provides a seedling transplanter that significantly reduces the structural complexity and control difficulty of the seedling clamping mechanism.

[0005] The technical solution adopted by this utility model is to provide a seedling transplanter, including a frame, a seedling storage mechanism, a seedling clamping mechanism and a seedling delivery mechanism set at the upper end of the frame, and a seedling planting mechanism set at the lower end of the frame. The input end of the seedling delivery mechanism corresponds to the output end of the seedling clamping mechanism, and the output end corresponds to the input end of the seedling planting mechanism. The seedling storage mechanism includes a seedling storage box set at the upper end of the frame, a seedling pushing motor set on the outer wall of the seedling storage box, a seedling pushing drive shaft rotatably set on the inner walls of both sides of the seedling storage box, a seedling pushing drive gear set on the seedling pushing drive shaft, a seedling pushing driven gear rotatably set on one inner wall of the seedling storage box and corresponding to the seedling pushing drive gear, a seedling pushing chain set on the seedling pushing drive gear and the seedling pushing driven gear, and a seedling pushing rod set on the seedling pushing chain.

[0006] The seedling storage box is a box structure with openings at the top and front. The seedling feeding mechanism is located at the front of the seedling storage box, the seedling clamping mechanism is located at the top of the seedling storage box, the seedling pushing drive shaft is located inside the bottom of the seedling storage box and one end passes through the side wall of the seedling storage box and is connected to the seedling pushing motor. The seedling pushing driven gear is located on one side inner wall of the top of the seedling storage box and corresponds to the seedling pushing drive gear. One end of the seedling pushing rod is fixed to the seedling pushing chain, and the other end faces the other side inner wall of the seedling storage box. The seedling pushing rod has the freedom to move up and down through the seedling pushing chain.

[0007] The seedling clamping mechanism includes an electric slide table mounted on a frame, a transverse frame mounted on the electric slide table, lifting sliders at both ends of the transverse frame, a lifting frame located at the lower end of the transverse frame, lifting rails at both ends of the lifting frame, a lifting cylinder mounted on the transverse frame, and a seedling clamping device mounted on the lifting frame. The electric slide table is located at the upper end of the seedling storage box and is transversely parallel to the seedling storage box. The lifting rails are located at the upper end of the seedling storage box and are perpendicular to the inside of the seedling storage box. The transverse frame is fixed to the moving end of the electric slide table. The outer side of the lifting slider is provided with a sliding groove adapted to the lifting rail. The lifting frame is slidably connected to the lifting slider through the lifting rails at both ends. The telescopic end of the lifting cylinder is fixed to the lifting frame. The clamping end of the seedling clamping device is perpendicular to the inside of the seedling storage box from the upper end of the seedling storage box.

[0008] The seedling feeding mechanism includes a first mounting shaft, a second mounting shaft, and a third mounting shaft mounted on the frame and located at the front opening of the seedling storage box; a first pulley, a second pulley, and a third pulley rotatably mounted on the first mounting shaft, the second pulley, and the third mounting shaft; a seedling feeding belt mounted on the first pulley, the second pulley, and the third pulley; a seedling box mounted on the outer end face of the seedling feeding belt; a seedling guard plate mounted on the frame and on one side of the first mounting shaft and the third mounting shaft; and a seedling feeding motor mounted on the frame. The seedling feeding motor is driven by the first pulley. The first mounting shaft, the second mounting shaft, and the third mounting shaft are arranged in a right-angled triangle. The first mounting shaft and the second mounting shaft are longitudinally and horizontally aligned, and the first mounting shaft and the third mounting shaft are vertically aligned. The output end of the seedling clamping mechanism corresponds to the first mounting shaft and the second mounting shaft. The seedling guard plate is spaced apart from the seedling feeding belt on the first pulley and the third pulley. The seedling box is a trough structure with openings at the front and top.

[0009] The seedling delivery mechanism also includes a transmission pulley rotatably mounted on the first mounting shaft, a drive pulley mounted on the output end of the seedling delivery motor, and a drive belt mounted on the transmission pulley and the drive pulley. The transmission pulley is fixed to the first pulley.

[0010] The first, second, and third pulleys are rotatably arranged in two sets on the first, second, and third mounting shafts, respectively, and are spaced apart vertically. The seedling feeding motor is provided in two sets, which are respectively connected to one set of first pulleys on the first mounting shaft and to the other set of third pulleys on the third mounting shaft.

[0011] It also includes a guide funnel set on the frame and located between the output end of the seedling delivery mechanism and the input end of the seedling planting mechanism.

[0012] The upper ends of the seedling storage mechanism, seedling clamping mechanism, and seedling delivery mechanism are inclined towards the rear side of the frame, and the inclination angles are the same.

[0013] The beneficial effects of this utility model are that it provides a seedling transplanter that adopts a step-type seedling storage mechanism. The clamping position of the seedling clamp changes from an increasing distance to a fixed distance, which effectively reduces the requirements for the stability and accuracy of the clamping mechanism and greatly reduces the structural complexity and control difficulty of the clamping mechanism.

Detailed Implementation

[0021] like Figure 1-2 and Figure 5As shown, this utility model provides a seedling transplanter, including a frame 1, a seedling storage mechanism, a seedling clamping mechanism and a seedling delivery mechanism disposed on the upper end of the frame 1, and a seedling planting mechanism disposed on the lower end of the frame 1. The input end of the seedling delivery mechanism corresponds to the output end of the seedling clamping mechanism, and the output end corresponds to the input end of the seedling planting mechanism. The seedling storage mechanism includes a seedling storage box 2 disposed on the upper end of the frame 1, a seedling pushing motor 3 disposed on the outer wall of the seedling storage box 2, a seedling pushing drive shaft 4 rotatably disposed on the inner walls of both sides of the seedling storage box 2, a seedling pushing drive gear 5 disposed on the seedling pushing drive shaft 4, a seedling pushing driven gear 6 rotatably disposed on the inner wall of one side of the seedling storage box 2 and corresponding to the seedling pushing drive gear 5, a seedling pushing chain 7 disposed on the seedling pushing drive gear 5 and the seedling pushing driven gear 6, and a seedling pushing rod 8 disposed on the seedling pushing chain 7.

[0022] The seedling storage box 2 is a box structure with openings at the top and front. The seedling feeding mechanism is located at the front of the seedling storage box 2, the seedling clamping mechanism is located at the top of the seedling storage box 2, the seedling pushing drive shaft 4 is located inside the bottom of the seedling storage box 2 and one end passes through the side wall of the seedling storage box 2 and is connected to the seedling pushing motor 3 for transmission. The seedling pushing driven gear 6 is located on one side of the inner wall of the top of the seedling storage box 2 and corresponds to the seedling pushing drive gear 5. One end of the seedling pushing rod 8 is fixed to the seedling pushing chain 7, and the other end faces the other side of the inner wall of the seedling storage box 2. The seedling pushing rod 8 has the freedom to move up and down through the seedling pushing chain 7.

[0023] The seedling tray is generally rectangular in structure, with multiple seedling storage troughs arranged in an array on it. This structure is existing technology, and can be found in publication number CN109121606A, entitled "A Crop Seedling Transplanter". The front side of the seedling storage box 2 refers to the side facing the traction end of the frame 1, and the two sides of the seedling storage box 2 refer to the two sides adjacent to the front side, namely the left and right sides. This design uses a duckbill-type planting mechanism, which is existing technology and will not be described in detail here. For ease of understanding, please refer to publication number CN117616953A, entitled "A Hanging Basket Duckbill Type Pineapple Transplanter with a Duckbill Planting Mechanism with Hole-Piercing, Soil-Covering, and Pressing Linkage Function", or publication number CN214757837U, entitled "Seedling Planting Mechanism of a Seedling Transplanter".

[0024] In use, this design involves manually placing a single seedling tray into the seedling storage box 2. The seedling pusher 8 is located at the lower end of the seedling storage box 2, without obstructing the placement of the seedling tray. The inner end of the seedling tray abuts against the seedling pusher 8. The output shaft of the seedling pusher motor 3, fixed to the left or right outer wall of the seedling storage box 2, is connected to the seedling pusher drive shaft 4, which drives the seedling pusher drive shaft 4 to rotate, thereby driving the seedling pusher active gear 5 to rotate. This, in conjunction with the seedling pusher driven gear 6, drives the seedling pusher chain 7 to perform a circular motion. The seedling pusher chain 7 is located on one side inside the seedling storage box 2, avoiding the seedling tray. The rotation of the seedling pusher chain 7 drives the seedling pusher 8 to move, pushing the seedling tray upward. After the seedling clamping mechanism clamps the first row of seedlings at the outer end of the seedling tray, the seedling pusher 8 pushes the seedling tray upward, so that the second row of seedlings on the seedling tray is in the clamping position of the seedling clamping mechanism. This process is repeated, with the seedling tray moving upward in a step-by-step manner, until all the seedlings on the seedling tray are clamped. Then, the empty seedling tray is manually removed, the seedling pusher 8 is reset, and a new seedling tray is placed in. This design can drive the seedling tray to perform step-by-step displacement, so that the seedling to be picked is in the picking position of the seedling picking mechanism. The seedling picking mechanism only needs to be positioned at one picking position, without increasing the movement stroke during picking, which effectively reduces the requirements for the stability and accuracy of the seedling picking mechanism, and greatly reduces the structural complexity and control difficulty of the seedling picking mechanism.

[0025] like Figure 3-5 As shown, the seedling clamping mechanism includes an electric slide table 9 mounted on the frame 1, a transverse frame 10 mounted on the electric slide table 9, lifting sliders 11 mounted at both ends of the transverse frame 10, a lifting frame 12 located at the lower end of the transverse frame 10, lifting slide rails 13 mounted at both ends of the lifting frame 12, a lifting cylinder 14 mounted on the transverse frame 10, and a seedling clamping device 15 mounted on the lifting frame 12.

[0026] The electric slide table 9 is located at the upper end of the seedling storage box 2 and is horizontally parallel to the seedling storage box 2. The lifting slide rail 13 is located at the upper end of the seedling storage box 2 and is vertically facing the inside of the seedling storage box 2. The horizontal moving frame 10 is fixed to the moving end of the electric slide table 9. The outer side of the lifting slider 11 is provided with a sliding groove that matches the lifting slide rail 13. The lifting frame 12 is slidably connected to the lifting slider 11 by means of the lifting slide rail 13 at both ends. The telescopic end of the lifting cylinder 14 is fixed to the lifting frame 12. The clamping end of the seedling clamp 15 is vertically facing the inside of the seedling storage box 2 from the upper end of the seedling storage box 2.

[0027] An electric slide table 9 is mounted on the frame 1 and is horizontally positioned at the upper end of the seedling storage box 2, parallel to the seedling storage box. A transverse frame 10 is fixed to the moving end of the electric slide table 9. The transverse frame 10 can be moved from inside the seedling storage box 2 toward the front opening of the seedling storage box 2 by the electric slide table 9. The lifting frame 12 is slidably connected to the lifting sliders 11 at both ends of the transverse frame 10 via lifting slide rails 13 at both ends. The specific connection method is not limited. For example, a dovetail groove is provided on the lifting slider 11, and the lifting slide rail 13 is slidably embedded in the groove. One end of the lifting slide rail 13 is located outside the upper opening of the seedling storage box 2, and the other end extends into the seedling storage box 2 and is parallel to the seedling storage box 2. The lifting cylinder 14 of the transverse frame 10 pushes the lifting frame 12 to move from outside the upper opening of the seedling storage box 2 toward the inside of the seedling storage box 2. The seedling clamp 15 is existing technology and will not be specifically limited or described.

[0028] In use, after the seedling tray is placed in the seedling storage box 2, the seedling clamp 15 is positioned at the first row of seedlings at the outer end of the seedling tray, i.e., the clamping position. After the seedling clamp 15 clamps the seedlings, driven by the electric slide table 9, the horizontal moving frame 10, the lifting frame 12, and the seedling clamp 15 move from inside the seedling storage box 2 toward the front opening of the seedling storage box 2. When the seedling clamp 15 moves to the corresponding position at the input end of the seedling delivery mechanism, i.e., the seedling placement position, the extension end of the lifting cylinder 14 pushes the lifting frame 12 toward the seedling placement position of the seedling delivery mechanism until it is in place. Then, the seedling clamp 15 releases, and the seedlings fall onto the seedling delivery mechanism, completing the seedling transfer. This design greatly reduces the structural complexity and control difficulty of the seedling clamping mechanism while ensuring the accuracy of seedling clamping and placement. It is also easy to assemble and operate.

[0029] like Figure 1 and Figure 5-6As shown, the seedling delivery mechanism includes a first mounting shaft 16, a second mounting shaft 17, and a third mounting shaft 18 mounted on the frame 1 and located at the front opening of the seedling storage box 2; a first pulley 19, a second pulley 20, and a third pulley 21 rotatably mounted on the first mounting shaft 16, the second mounting shaft 17, and the third mounting shaft 18; a seedling delivery belt 22 mounted on the first pulley 19, the second pulley 20, and the third pulley 21; a seedling box 23 mounted on the outer end face of the seedling delivery belt 22; and a seedling guard plate 24 mounted on the frame 1 and on one side of the first mounting shaft 16 and the third mounting shaft 18. A seedling feeding motor 25 is mounted on the frame 1; the seedling feeding motor 25 is connected to the first pulley 19 for transmission; the first mounting shaft 16, the second mounting shaft 17 and the third mounting shaft 18 are arranged in a right-angled triangle; the first mounting shaft 16 and the second mounting shaft 17 are longitudinally and horizontally aligned; the first mounting shaft 16 and the third mounting shaft 18 are vertically aligned; the output end of the seedling clamping mechanism is aligned with the first mounting shaft 16 and the second mounting shaft; the seedling guard plate 24 is spaced apart from the seedling feeding belt 22 on the first pulley 19 and the third pulley 21; the seedling box 23 is a groove structure with openings at the front and top.

[0030] The first pulley 19, the second pulley 20, and the third pulley 21 are arranged in a right-angled triangle outside the front opening of the seedling storage box 2 and are parallel to the seedling storage box 2. The first pulley 19, the second pulley 20, and the seedling delivery belt 22 of this section form the right-angled side of the upper end of the right-angled triangle, and the first pulley 19, the third pulley 21, and the seedling delivery belt 22 of this section form the right-angled side of the lateral side of the right-angled triangle.

[0031] Driven by the seedling feeding motor 25, the seedling feeding belt 22 moves in a ring on the first pulley 19, the second pulley 20, and the third pulley 21. The seedling box 23 is a groove structure with openings at the front and top. The seedling box 23 is fixed on the seedling feeding belt 22, with its rear end facing the seedling storage box 2. After the seedling clamping device 15 of the seedling clamping mechanism clamps the seedling, it moves to a position above the seedling box 23. After releasing the seedling, the seedling falls into the seedling box 23. The seedling box 23, filled with seedlings, is driven by the seedling feeding belt 22 and moves in a ring on the first pulley 19, the second pulley 20, and the third pulley 21. The seedling box 23 moves between the first pulley 19 and the third pulley 21. At this time, the opening on the upper side of the seedling box 23 faces the left or right side. The seedling guard plate 24 on the frame 1 blocks the opening of the seedling box 23 to prevent the seedlings from leaking out. When the seedling box 23 moves to the third pulley 21, it moves out of the range that the seedling guard plate 24 can cover. The seedlings in the seedling box 23 fall into the planting mechanism. At this time, the movement of the seedling box 23 changes from uniform movement to step movement to ensure that the seedlings can fall into the planting mechanism one by one at intervals.

[0032] like Figure 1 and Figure 6 As shown, the seedling delivery mechanism also includes a transmission pulley 26 rotatably mounted on the first mounting shaft 16, a drive pulley 27 mounted on the output end of the seedling delivery motor 25, and a drive belt mounted on the transmission pulley 26 and the drive pulley 27. The transmission pulley 26 is fixed to the first pulley 19.

[0033] The transmission structure of the seedling delivery mechanism consists of a transmission pulley 26, a drive pulley 27, and a drive belt. Only one transmission pulley 26 needs to be rotatably installed and fixed to the first pulley 19. When the seedling delivery motor 25 drives the transmission pulley 26 to rotate, it drives the first pulley 19 to rotate synchronously, thereby driving the seedling delivery belt 22 to perform circular motion.

[0034] like Figure 1 and Figure 6 As shown, the first pulley 19, the second pulley 20, and the third pulley 21 are rotatably arranged in two sets on the first mounting shaft 16, the second mounting shaft 17, and the third mounting shaft 18, respectively, and are spaced apart vertically. The seedling feeding motor 25 is provided in two sets, which are respectively connected to one set of the first pulley 19 on the first mounting shaft 16 and to the other set of the third pulley 21 on the third mounting shaft 18.

[0035] The seedling conveyor belt 22 is also equipped with two sets, and each set of seedling conveyor belt 22 is equipped with a seedling box 23. The seedling boxes 23 are staggered in position on the seedling conveyor belt 22. When the seedling box 23 moves to the third pulley 21, the movement of the seedling box 23 changes from uniform speed to stepping speed. The other seedling box 23 moves at a uniform speed to the seedling clamping mechanism to receive the seedlings clamped by the seedling clamp 15, forming a more efficient continuous operation and greatly improving the working efficiency of the seedling conveyor mechanism.

[0036] like Figure 1 As shown, it also includes a guide funnel 28 set on the frame 1 and located between the output end of the seedling delivery mechanism and the input end of the seedling planting mechanism.

[0037] The upper end of the guide funnel 28 has a large opening, which corresponds to the position where the seedlings fall in the seedling box 23, and the lower end has a small opening, which corresponds to the input end of the planting mechanism. This can guide the falling of the seedlings, reduce the accuracy of the seedling position of the seedling box 23, and improve the accuracy of the seedlings falling into the planting mechanism.

[0038] like Figure 1 As shown, the upper ends of the seedling storage mechanism, seedling clamping mechanism and seedling delivery mechanism are inclined towards the rear side of the frame 1 and the inclination angles are the same.

[0039] The inclined arrangement makes it easier to manually place and replace the seedling trays, while the inclined surface ensures that the seedling trays will not tip over in the seedling storage box 2, eliminating the need for additional limiting structures.
