From top to bottom on the frame, there are a soil collection box, a soil screening box, a soil guiding groove and a sowing box in sequence. A hollow soil shoveling plate is connected to the soil collection box. One end of the soil screening box is hinged to the frame, and the other end of the soil screening box is slidably connected to the frame. A first spring is connected between the soil screening box and the frame. A negative pressure mechanism and a driving mechanism are provided on the frame. Leakage holes are opened on the soil screening box. A soil covering plate is connected to the soil guiding groove. A first wedge plate is slidably connected to the frame.

[0020] With the above technical solution, by the cooperation of the movable rotating rod, the stirring frame, the twist rod and the reset spring, the stirring frame and the movable rotating rod can be driven to move up and down reciprocally when the transmission disc rotates.

[0024] With the above technical solution, through the sliding connection between the transmission rod and the transmission shaft, the transmission of the transmission rod can be maintained when the transmission shaft moves, and the transmission rod is used to drive the first pulley to rotate. The first pulley drives the second pulley and the first rotating rod to rotate through the transmission belt, thereby providing rotational power for the blanking mechanism.

[0025] Preferably, a positioning seat is fixed at the front end of the transmission box, and a second screw rod is rotatably connected to the front end of the positioning seat. The left end of the transmission shaft is rotatably connected to a transmission plate, and the transmission plate is threadedly connected to the second screw rod.

[0026] With the above technical solution, by installing the second screw rod through the positioning seat, when the second screw rod rotates, the position of the transmission shaft and the second gear set can be adjusted by using the transmission plate, thereby changing the meshing of gears of different sizes in the two gear sets and changing the transmission ratio.

[0027] Preferably, transmission pipes are arranged on both sides of the first positioning shaft, and the lower end of the transmission pipe is designed in a "T" shape. The soil covering rollers are distributed mirror-symmetrically at the left and right ends of the transmission pipe, and the soil covering rollers are rotatably connected to the lower end of the transmission pipe. The opposite sides of the soil covering rollers are designed in a conical shape. The upper end of the rear side of the support rod is fixed with a support frame, and the support frame is designed in an "L" shape and is connected to the upper end of the transmission pipe.

[0028] With the above technical solution, through the design of the two soil covering rollers, they can move and rotate synchronously with the sowing equipment, thereby backfilling the soil on both sides of the opened ditch and covering the seeds in the ditch.

[0029] Preferably, a liquid storage tank is arranged at the upper end of the rear side of the equipment frame, and a corrugated hose is connected to the lower side of the rear end of the liquid storage tank.

The transmission connecting rod is rotatably connected to the transmission pipe, and the soil covering rollers on both sides of the transmission pipe are respectively fixed to both ends of the transmission connecting rod.

[0030] With the above technical solution, through the connection between the impeller and the transmission pipe, the impeller and the transmission connecting rod can rotate synchronously with the soil covering rollers, thereby discharging the liquid conveyed by the corrugated hose, and then watering the sown pepper seeds to facilitate subsequent growth.

[0031] Preferably, a damping reset device is rotatably connected to the upper end of the support rod, and the upper end of the damping reset device is rotatably connected to the equipment frame.

The rear end of the stirring shaft extends outside the liquid storage tank, and a transmission gear is connected to the rear end of the stirring shaft. The transmission gear is meshed with the transmission rack.

[0033] By adopting the above technical solution, the design of the damping reset device can avoid the influence of ground unevenness on the stability of the seeding equipment during the traveling process. Moreover, by using the cooperation of the movable rod and the second positioning shaft, when the support rod drives the positioning chute to move, the movable rod, the transmission frame and the transmission rack are synchronously driven to rise and fall. When the transmission rack rises and falls, it can drive the transmission gear, the stirring shaft and the second stirring rod to rotate, so as to stir the liquid inside the liquid storage tank.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: The automatic pepper seeding equipment with the function of adjusting the planting spacing can control the spacing to sow pepper seeds during the traveling process of the seeding equipment through the setting of a quantitative and uniform feeding mechanism. Moreover, because the feeding mechanism is linked with the roller, the seeding spacing will not be affected by the traveling speed of the seeding equipment, thus improving the operation convenience.

[0035] 1. By setting a transmission mechanism, the transmission ratio between the feeding mechanism and the roller can be adjusted, and different feeding speeds of the feeding mechanism can be adjusted, so as to change the seeding spacing of peppers, which can be applicable to the seeding of different varieties of peppers and maintain a suitable planting spacing to adapt to the growth of pepper plants.

[0036] 2. By setting a soil covering structure, the soil on both sides of the seeding trench can be backfilled and covered with soil after pepper seeding. And with the cooperation of a watering structure, the liquid can be guided and watered while the soil covering roller rotates. Moreover, when traveling, the stirring structure can be driven by the movement of the support rod to stir the liquid inside the liquid storage tank. If synchronous fertilization is required, the water-fertilizer mixture can be stirred evenly. Brief Description of the Drawings

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] Please refer to Figures 1-12, the present invention provides a technical solution: an automatic pepper seeding device with a function of adjusting the planting spacing, including a device frame 1 and rollers 2. Rollers 2 are symmetrically installed on both sides of the device frame 1. A furrow opener 3 is arranged at the lower side of the front end of the device frame 1. A movable frame 4 is fixed to the upper end of the furrow opener 3. A positioning plate 5 is fixed inside the front end of the device frame 1. A positioning frame 6 is fixed to the upper end of the positioning plate 5. A threaded lead screw 7 passes through the middle of the positioning frame 6; the furrow openers 3 are symmetrically distributed at the left and right ends of the movable frame 4. The upper end of the movable frame 4 extends into the positioning frame 6. The movable frame 4 is slidably connected to the positioning frame 6. The threaded lead screw 7 is threadedly connected to the positioning frame 6. The lower end of the threaded lead screw 7 passes through the positioning plate 5. The bottom end of the threaded lead screw 7 is rotatably connected to the movable frame 4; the forward direction of the pepper seeding device is defined as the front of the device; the device frame 1 can be supported by the rollers 2. When the seeding device moves forward, the furrow opener 3 is used to open furrows on the ground to facilitate subsequent seeding. To adapt to different varieties of pepper seeding, the height of the furrow opener 3 can be adjusted. By rotating the threaded lead screw 7, the movable frame 4 and the furrow opener 3 are driven to rise and fall to change the depth of the furrow opening. The cooperation between the movable frame 4 and the positioning frame 6 can improve the stability of the furrow opener 3.

[0052] There is a blanking mechanism in the middle of the equipment frame 1. The blanking mechanism includes a storage bin 8, a blanking pipe 9, a first rotating rod 10 and a material limiting plate 11. The material limiting plate 11 is designed in a fan-shaped structure. The storage bin 8 is symmetrically installed at the upper end of the middle part of the equipment frame 1, and the lower end of the storage bin 8 is conductively connected to the blanking pipe 9. The middle part of the blanking pipe 9 is designed in a circular structure, and the blanking pipe 9 is rotatably connected to the first rotating rod 10. The material limiting plate 11 is fixedly connected to the outer wall of the first rotating rod 10, and the material limiting plates 11 are distributed in a circular array with the center of the first rotating rod 10 as the axis. Moreover, the end of the material limiting plate 11 contacts the inner wall of the circular part of the blanking pipe 9. There is a transmission disc 12 inside the blanking pipe 9, and the transmission disc 12 is fixed to the middle of the material limiting plate 11. The inner wall of the upper end of the storage bin 8 is connected with a twist rod 16, and a movable rotating rod 13 is threadedly connected to the lower end of the twist rod 16. The outer wall of the lower end of the movable rotating rod 13 is connected with a stirring frame 14, and the stirring frames 14 are distributed in a circular array. The upper end of the movable rotating rod 13 is rotatably connected to a positioning disc, and a return spring 15 is fixed to the upper end of the positioning disc, and the top end of the return spring 15 is connected to the inner wall of the storage bin 8. A limiting groove 17 is formed on the outer wall of the transmission disc 12, and the limiting grooves 17 are distributed in a circular array with the first rotating rod 10 as the center. The lower end of the movable rotating rod 13 is designed in a spherical shape, and the lower end of the movable rotating rod 13 contacts the limiting groove 17. The pepper seeds are stored in the storage bin 8 and cooperate with the blanking pipe 9 for blanking. When the first rotating rod 10 rotates, it can drive multiple groups of material limiting plates 11 and the transmission disc 12 to rotate. The adjacent two groups of material limiting plates 11 can accurately control the blanking amount of the pepper seeds. And after the seeds are blanked between the two groups of material limiting plates 11, because the material limiting plate 11 is fan-shaped, the material limiting plate 11 can only blank again after rotating a certain angle, which takes a certain amount of time, thus achieving the effect of intermittent blanking, and the blanking speed is controlled by the rotation speed of the first rotating rod 10. By using the cooperation of the limiting groove 17, the movable rotating rod 13, the return spring 15 and the twist rod 16, when the transmission disc 12 rotates, the limiting groove 17 drives the movable rotating rod 13 to reciprocate up and down. Because the twist rod 16 cannot rotate, when the movable rotating rod 13 moves up and down, the relative position between the movable rotating rod 13 and the twist rod 16 changes, thereby driving the movable rotating rod 13 to rotate. And the design that the positioning disc is rotatably connected to the movable rotating rod 13 can prevent the movable rotating rod 13 from being interfered by the return spring 15 when rotating. When the movable rotating rod 13 drives the stirring frame 14 to rotate, it can stir the materials inside the storage bin 8. If the seeds are mixed with a medicament, the mixing uniformity can be improved, and the probability of blanking blockage can be reduced during stirring.

[0053] There is a second rotating rod 18 connected between the two sets of rear rollers 2, and a transmission mechanism is arranged in the middle of the second rotating rod 18. The transmission mechanism includes a transmission box 19, a first gear set 20, a transmission shaft 21, and a second gear set 22.

Both the first gear set 20 and the second gear set 22 include three gears with different diameters. The diameters of the three gears in the first gear set 20 increase from right to left, and the diameters of the three gears in the second gear set 22 decrease from right to left. The gear spacing of the first gear set 20 is greater than the gear spacing of the second gear set 22, and the gear diameters of the first gear set 20 and the second gear set 22 are adapted to each other; on the right side of the front end of the transmission box 19, there is a rotatably connected transmission rod 23, and the left end of the transmission rod 23 is designed with a square structure. The square part at the left end of the transmission rod 23 extends into the transmission shaft 21, and the left end of the transmission rod 23 is slidably connected to the transmission shaft 21.

The left end of the transmission shaft 21 is rotatably connected to a transmission plate 29, and the transmission plate 29 is threadedly connected to the second screw rod 28; through the design of the transmission box 19, power can be provided for the feeding mechanism when the roller 2 rotates, and the transmission ratio can be adjusted to change the sowing spacing of pepper seeds. During use, the second rotating rod 18 drives the first gear set 20 to rotate, and the first gear set 20 drives the transmission shaft 21, the transmission rod 23, and the first pulley 24 to rotate synchronously through the second gear set 22. The first pulley 24 drives the second pulley 25 and the first rotating rod 10 to rotate synchronously by using the transmission belt 26, thereby providing rotational power for the feeding mechanism. And the position of the transmission plate 29 and the transmission shaft 21 can be adjusted by manually rotating the second screw rod 28 before sowing to change the meshing of the gears with different diameters of the first gear set 20 and the second gear set 22 and change the transmission ratio between the second rotating rod 18 and the transmission shaft 21. The distance between the adjacent and approximate sides of the two adjacent gears in the first gear set 20 is greater than the distance between the remote ends of the two adjacent gears in the second gear set 22 to ensure that only one set of gears is engaged during transmission.

[0054] A soil covering mechanism is provided at the rear end of the equipment frame 1.

A liquid storage tank 39 is provided at the upper rear side of the equipment frame 1. A corrugated hose 38 is connected to the lower side of the rear end of the liquid storage tank 39, and the end of the corrugated hose 38 is conductively connected to the upper end of the transmission pipe 33. An impeller 37 is provided inside the transmission pipe 33, and a transmission connecting rod 36 is connected to the middle of the impeller 37.

The transmission connecting rod 36 is rotatably connected to the transmission pipe 33, and the soil covering rollers 32 on both sides of the transmission pipe 33 are respectively fixed to both ends of the transmission connecting rod 36. Through the design of the conical soil covering roller 32, the soil on both sides of the sowing ditch can be squeezed, backfilled, and covered with soil. By the cooperation of the support rod 30 and the support frame 34, the transmission pipe 33 and the first positioning shaft 31 can be positioned and installed respectively. The transmission pipe 33 keeps the positioning of the soil covering rollers 32 on both sides of it, while the two soil covering rollers 32 on both sides of the first positioning shaft 31, which are close to the left - right central axis of the equipment frame 1, are connected to keep the two soil covering rollers 32 on both sides rotating synchronously. The support rod 30 is connected and installed at the rear end of the sowing equipment through the second rotating rod 18. During the traveling process, the soil covering roller 32 rotates and drives the impeller 37 to rotate through the transmission connecting rod 36. The water - fertilizer mixture in the liquid storage tank 39 can be transported to the inside of the transmission pipe 33 through the corrugated hose 38. During the rotation of the impeller 37, the impeller 37 continuously transports the water flowing down inside the transmission pipe 33 downward and flows out through the hole at the bottom end of the transmission pipe 33 to irrigate the sown pepper seeds, providing sufficient water and nutrients for the subsequent germination and growth of peppers. The setting of the support frame 34 fixes the transmission pipe 33 to prevent it from rotating with the soil covering roller 32.

The rear end of the stirring shaft 40 extends outside the liquid storage tank 39, and a transmission gear 47 is connected to the rear end of the stirring shaft 40, and the transmission gear 47 is meshed with the transmission rack 46. The liquid storage tank 39 can store water or a water-fertilizer mixture. Since the support rod 30 can rotate around the second rotating rod 18, it can avoid the shaking and bumping of the seeding equipment caused by large soil clods or uneven ground during the traveling process. The damping reset device 35 is used to perform a downward rotation reset on the soil covering roller 32. The reset elastic force provided by the damping reset device 35 can better push the soil clods into the seeding trench.
