[0018] like Figures 1 to 4 As shown, a seed ball making device includes a frame 1, and a seed dispensing mechanism 2, a soil covering mechanism 3, a ball forming mechanism 4, and a collecting hopper 5 mounted on the frame 1. The seed dispensing mechanism 2 includes a seed storage tray 6 for storing seeds, and a seed picking and placing component for picking up and placing seeds from the seed storage tray 6 to the ball forming mechanism 4. The seed picking and placing component includes a seed suction tray 7 for absorbing seeds, and a plurality of seed suction grooves 8 are evenly distributed on the seed suction tray 7. The soil covering mechanism 3 includes a soil storage hopper 9, and the soil storage hopper 9 has a soil discharge port 10 for discharging soil. The inlet 10 is equipped with a mud-collecting wheel 11 for pouring the soil from the soil storage hopper 9 into the ball-forming mechanism 4. The ball-forming mechanism 4 includes a bottom template 12 and a pressing template 13. The bottom template 12 is provided with a forming groove 14 corresponding to the seed suction groove 8, and the bottom template 12 is connected to a flipping structure 15 that drives it to flip. The pressing template 13 is connected to a pressing template driving structure that drives it to move toward or away from the bottom template 12, and the surface of the pressing template 13 facing the bottom template 12 is provided with a pressing cup 16 corresponding to the forming groove 14.

[0019] This utility model discloses a seed mud ball making device, which includes a seed feeding mechanism 2, a soil covering mechanism 3, a ball forming mechanism 4, and a collection hopper 5. First, the soil covering mechanism 3 covers a layer of soil into the forming groove 14 on the bottom template 12. Then, the seed feeding mechanism 2 puts seeds into the forming groove 14. The soil covering mechanism 3 then covers another layer of soil into the forming groove 14 on the bottom template 12. Finally, the pressure cup 16 on the pressure template 13 compacts the soil in the forming groove 14, thereby realizing the processing and forming of seed mud balls. The device has a high degree of automation and improves the production efficiency of seed mud balls. Furthermore, since the seed suction plate 7 in the seed feeding mechanism 2 has a corresponding seed suction groove 8 that corresponds to the forming groove 14 on the bottom template 12, during the seed feeding process, the seed suction plate 7 can efficiently suck the same number of seeds into the seed suction groove 8 and then put them into the forming groove 14, thereby ensuring that the number of seeds in each forming groove 14 is the same, thus improving the uniformity of the number of seeds in the seed mud balls.

[0020] Specifically, in one preferred embodiment of this application, the seed storage tray 6 can be a steering wheel body with an open top. The seed storage tray 6 can be fixedly installed on the frame 1, and the bottom of the seed storage tray 6 is provided with a seed storage trough 17 corresponding to the seed suction trough 8. Specifically, the seed storage troughs 17 are evenly distributed at the bottom of the seed storage tray 6 and have multiple rows and columns. The number and position of the seed suction trough 8 and the forming trough 14 are corresponding to the seed storage troughs 17. By providing the seed storage troughs 17, the operator only needs to put the seeds into the seed storage troughs 17 when releasing the seeds. Moreover, each seed storage trough 17 is the same size, so the number of seeds put into each seed storage trough 17 is also the same. If it is necessary to adjust the number of seeds put in, or to put in different types of seeds, only the size of the seed storage trough 17 needs to be adjusted.

[0021] In this application, the seed-laying assembly can be positioned above the seed storage tray 6. It includes a seed-laying frame 18 that slides with the frame 1, and a first horizontal drive structure that drives the seed-laying frame 18 to move between the seed storage tray 6 and the ball-forming mechanism 4. Specifically, in one embodiment of the first horizontal drive structure, racks are symmetrically arranged on opposite sides of the seed-laying frame 18 on the frame 1. Drive motors are arranged on both sides of the seed-laying frame 18, and gears meshing with the racks are mounted on the output shafts of the drive motors. The drive motors drive the gears to rotate, thereby enabling the seed-laying frame 18 to move along the racks, thus achieving seed-laying... The seed rack 18 moves horizontally, and the seed suction plate 7 is installed on the seed rack 18 and connected to a vertical drive structure 19 that drives it to move vertically. The vertical drive structure 19 drives the seed suction plate 7 to move vertically, thereby sucking the seeds in the seed storage plate 6 into the seed suction groove 8, or putting the seeds in the seed suction groove 8 into the forming groove 14. The vertical drive structure 19 can adopt a drive cylinder structure in the prior art, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, etc. The seed suction groove 8 can be connected to a negative pressure suction structure, so that the seed suction groove 8 has negative pressure to suck the seeds into the seed suction groove 8.

[0022] Furthermore, a first guide sleeve 20 can be provided on the seed-laying frame 18, and a first guide rod 21 that cooperates with the first guide sleeve 20 is provided on the seed-suction plate 7. Both the first guide sleeve 20 and the first guide rod 21 are vertically arranged. Through the sliding cooperation between the first guide rod 21 and the first guide sleeve 20, the movement of the seed-suction plate 7 is limited, so that the seed-suction plate 7 can maintain stable vertical movement. In order to provide the balance of force on the seed-suction plate 7, the first guide rods 21 can be symmetrically arranged on opposite sides of the seed-suction plate 7.

[0023] In another specific embodiment of this application, the soil covering mechanism 3 further includes a soil covering frame 22, a soil storage hopper 9 is installed on the soil covering frame 22, the soil covering frame 22 is slidably installed on the frame 1, and is connected to a second horizontal drive structure that drives it to move toward or away from the ball forming mechanism 4. Specifically, the second horizontal drive structure can adopt the same structure as the first horizontal drive structure.

[0024] Preferably, a soil inlet hopper 23 can be fixedly installed above the soil storage hopper 9. The soil inlet hopper 23 is set downwards, with its upper end extending out of the frame 1 and having a soil inlet, and its lower end extending to the top of the soil storage hopper 9 and having a soil outlet. By providing the soil inlet hopper 23, it is convenient for operators to add soil to the soil storage hopper 9.

[0025] In this embodiment, the mud-collecting wheel 11 may include a mud-collecting shaft 24. Both ends of the mud-collecting shaft 24 are rotatably connected to the frame 1 through bearing seats, and one end is connected to a drive motor that drives its rotation. Several sets of mud-collecting units are evenly distributed along the circumference of the mud-collecting shaft 24. Each set of mud-collecting units includes multiple mud-collecting scoops 25 evenly distributed along the axial direction of the mud-collecting shaft 24. The mud-collecting scoops 25 on each set of mud-collecting units can correspond one-to-one with the forming grooves 14 on each column of forming grooves 14. Therefore, after the soil covering frame 22 moves above the bottom template 12, it can add soil to each column of forming grooves 14 on the bottom template 12 in sequence during the movement.

[0026] In another specific embodiment of this application, the bottom template 12 is rotatably mounted on the bottom template base 26. Specifically, shafts are provided on opposite sides of the bottom template 12, and the shafts are rotatably engaged with bearing seats on the frame 1. The flipping structure 15 can be a rotary cylinder, which drives the bottom template 12 to rotate. The bottom template base 26 is connected to a third horizontal drive structure that drives it to move toward or away from the pressing template 13. Specifically, the third horizontal drive structure can also adopt the same structure as the first horizontal drive structure. At the same time, a second guide slide rod 27 is provided on the frame 1, and a second guide sleeve 28 is provided on the bottom template base 26 that slides with the second guide slide rod 27. The arrangement structure of the second guide slide rod 27 and the second guide sleeve 28 can adopt the same structure as the first guide slide rod 21 and the first guide sleeve 20.

[0027] In this application's seed mud ball making device, the initial position of the bottom mold base 26 is in the middle of the frame 1. The operator adds a certain amount of soil to the mud storage hopper and an appropriate amount of seeds to the seed storage trough 17. The soil covering frame 22 moves towards the bottom template 12, evenly covering the forming groove 14 on the bottom template 12 with a layer of soil. After completion, it returns to its original position. The seed placement frame 18 moves above the seed storage tray 6, driving the seed suction plate 7 to move downwards, sucking the seeds in the seed storage trough 17 into the seed suction trough 8. Then, it moves to directly above the bottom template 12, and the seed suction plate 7 moves downwards. Stop attracting the seeds, causing them to fall into the forming groove 14 of the bottom template 12. Then, the seed placement rack 18 is reset, and the soil storage hopper 9 on the soil covering rack 22 repeats the soil covering action. After the soil covering is completed, it returns to its original position. Then, the bottom mold base 26 moves to the bottom of the pressing template 13 and drives the pressing template 13 to move downward, so that the pressing cup 16 on the pressing template 13 compacts the soil in the forming groove 14. After completion, it is reset, and the bottom mold base 26 returns to the middle position of the frame 1. The rotating structure drives the bottom template 12 to rotate 180 degrees, causing the mud ball to fall into the collection hopper 5, thus completing the production of the seed mud ball.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
