Description

Technical Field

[0001] This utility model relates to the technical field of soil conditioner spraying equipment, specifically a soil conditioner spraying equipment for soil improvement. Background Technology

[0002] Soil conditioner spraying equipment is a type of machinery specifically designed to evenly spray soil conditioners onto farmland or soil surfaces. Typically, the working principle involves a pump drawing the soil conditioner from a storage tank, atomizing it into fine particles through a spray pipe and nozzles, and then spraying it evenly onto the soil surface. The control system can adjust the pump flow rate and the nozzle spray angle to ensure uniform application of the soil conditioner.

[0003] A Chinese patent (publication number: CN217963047U) discloses a soil conditioner spraying device for agricultural production, including a wheelbarrow with a trough and a spraying assembly for spraying soil conditioner. The spraying assembly includes a reagent tank and an atomizing nozzle mounted on the wheelbarrow. A soil turning assembly for turning the soil is fixedly connected to the front end of the wheelbarrow. By utilizing a rotating rod in the soil turning assembly and an arc-shaped blade fixedly connected to the rotating rod, the rotating arc-shaped blade turns the soil to be sprayed with soil conditioner. After turning, the soil conditioner is transported to the atomizing nozzle through a high-pressure water pump and pipeline, thereby achieving the purpose of spraying soil conditioner. By spraying the soil conditioner onto the turned soil, the rate at which the soil conditioner improves the soil quality can be further accelerated.

[0004] During the spraying process, the above-mentioned equipment can spray the soil by setting multiple nozzles that can be raised and lowered. However, during the spraying process, the nozzles of this device can only be adjusted in the up and down direction. The topography of the soil is not constant. When facing uneven and undulating plots, the nozzles that spray in a fixed direction may spray too much in higher areas and too little in lower areas, affecting the soil improvement or crop protection effect and making it difficult to ensure that the pesticide is sprayed evenly to all locations.

[0005] To address these issues, we designed a soil conditioner spraying device. Utility Model Content

[0006] The purpose of this invention is to provide a soil conditioner spraying device for soil improvement, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a soil conditioner spraying device for soil improvement, including a tractor vehicle. A connecting frame is detachably connected to the rear of the tractor vehicle via a pin. Two symmetrical connecting rollers are rotatably mounted on the connecting frame. A connecting shaft is coaxially mounted on one side of each connecting roller. A transmission gear is detachably connected to the connecting shaft. A driven gear is meshed on one side of the transmission gear. A spraying frame is connected to one side of the driven gear. A spraying pipe for spraying is installed inside the spraying frame.

[0008] Furthermore, a connecting seat is connected to the connecting frame, and a return spring is connected to the connecting seat. The other end of the return spring is connected to the spraying frame.

[0009] Furthermore, a limiting nut is threaded onto the connecting shaft, and the limiting nut is used to fix the transmission gear.

[0010] Furthermore, the spray pipe is rotatably connected inside the spray frame, and multiple atomizing nozzles are connected to the bottom of the spray pipe. The multiple atomizing nozzles are distributed in a linear array at equal intervals along the axial direction of the spray pipe.

[0011] Furthermore, both ends of the spray pipe extend to the outside of the spray frame and are connected to a transmission ring, and a limiting ring is provided on one side of the spray frame to limit the movement of the transmission ring.

[0012] Furthermore, a fixed seat is connected to the spray frame, and a threaded rod is threadedly connected to the fixed seat. The other end of the threaded rod is rotatably connected to one side of a limiting ring, and the limiting ring is slidably connected to the spray frame.

[0013] Furthermore, a storage box is connected to the connecting frame, and a water pump is connected to one side of the storage box. The water pump is connected to the spray pipe through an installation pipe.

[0014] Furthermore, a stirring rack is rotatably connected inside the storage tank, and a servo motor for driving the stirring rack to rotate is connected to the storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By connecting the rollers to the ground, the connecting shaft and the irregularly shaped incomplete transmission gear can be rotated according to the terrain undulations. This intermittently engages the driven gear to drive the spray frame to adjust its angle. The return spring can quickly pull the spray frame back to its initial position when the gears disengage. This setting allows the spray frame to adaptively adjust with changes in terrain, improving the spraying effect.

[0017] 2. The spray pipe can rotate around its own axis, and the spray direction of the bottom atomizing nozzles can be adjusted according to the actual needs of the plot, so as to achieve coverage of special areas such as corners and slopes. At the same time, multiple atomizing nozzles are distributed in a linear array with equal spacing along the axis of the spray pipe, which widens the coverage of the spray structure and avoids the problem of local missed spraying caused by uneven distribution of traditional nozzles. This setting improves the uniformity of soil conditioner adhesion under different terrain conditions. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a soil conditioner spraying device for soil improvement, including a tractor 1, a connecting frame 2 detachably connected to the rear of the tractor 1 by means of a pin, two symmetrical connecting rollers 3 rotatably mounted on the connecting frame 2, a connecting shaft 4 coaxially mounted on one side of the connecting rollers 3, a transmission gear 5 detachably connected to the connecting shaft 4, a driven gear 6 meshing with one side of the transmission gear 5, a spraying frame 7 connected to one side of the driven gear 6, and a spraying pipe 10 for spraying installed inside the spraying frame 7.

[0025] It should be noted that transmission gear 5 is an irregularly shaped, incomplete gear.

[0026] In practice, when the tractor 1 moves, the connecting rollers 3 on the connecting frame 2 directly contact the ground and roll with the terrain, driving the coaxial connecting shaft 4 to rotate synchronously. Since the transmission gear 5 is an irregularly shaped incomplete gear, it intermittently meshes with the driven gear 6 when it rotates, driving the spray frame 7 to rotate around the connection point. At the same time, the spray pipe 10 is fixed inside the spray frame 7, and adjusts the overall spraying direction according to the angle change of the spray frame 7, ensuring that the nozzle is always aimed at the soil surface. This setting realizes the terrain adaptive adjustment of the spray frame 7, avoiding the problem of excessive spraying on high ground and insufficient spraying on low ground when spraying in a fixed direction.

[0027] See Figure 1-4 A connecting bracket 8 is connected to the connecting frame 2, and a return spring 9 is connected to the connecting bracket 8. The other end of the return spring 9 is connected to the spray frame 7.

[0028] In practice, when the connecting roller 3 drives the spray frame 7 to rotate upward or downward, the return spring 9 is stretched or compressed accordingly, generating a reverse elastic force; when the transmission gear 5 disengages from the driven gear 6, the elastic force of the return spring 9 can quickly pull the spray frame 7 back to its initial position.

[0029] See Figure 1-4 A limit nut 19 is threaded onto the connecting shaft 4, and the limit nut 19 is used to fix the transmission gear 5.

[0030] In practice, a limit nut 19 is threaded onto the connecting shaft 4. After the transmission gear 5 is fitted onto the connecting shaft 4, the limit nut 19 is tightened to fix the transmission gear 5 axially and prevent it from sliding. At the same time, the transmission gear 5 can be replaced according to actual working needs. When replacing, the limit nut 19 can be loosened to disassemble it.

[0031] See Figure 1-4 The spray pipe 10 is rotatably connected to the spray frame 7. Multiple atomizing nozzles 11 are connected to the bottom of the spray pipe 10. The multiple atomizing nozzles 11 are distributed in a linear array at equal intervals along the axial direction of the spray pipe 10.

[0032] In practice, the spray pipe 10 is rotatably connected to the spray frame 7, and multiple atomizing nozzles 11 are distributed at equal intervals in a linear array along the axial direction at its bottom. The spray pipe 10 can rotate around its own axis to adjust the direction of the nozzles. In conjunction with the overall angle adjustment of the spray frame 7, multi-dimensional spray coverage can be achieved.

[0033] See Figure 1-4 Both ends of the spray pipe 10 extend to the outside of the spray frame 7 and are connected to the drive ring 15. A limiting ring 14 is provided on one side of the spray frame 7 to limit the movement of the drive ring 15.

[0034] In practice, the two ends of the spray pipe 10 extend to the outside of the spray frame 7 and are connected to the transmission ring 15. The limiting ring 14 on one side of the spray frame 7 is sleeved on the outside of the transmission ring 15 to form an axial limit on the transmission ring 15. When the spray pipe 10 rotates, the transmission ring 15 rotates synchronously with the spray pipe 10. The limiting ring 14 restricts the axial movement of the transmission ring 15, thereby preventing the spray pipe 10 from moving.

[0035] See Figure 1-4 A fixed seat 12 is connected to the spray frame 7, and a threaded rod 13 is threadedly connected to the fixed seat 12. The other end of the threaded rod 13 is rotatably connected to one side of the limiting ring 14, and the limiting ring 14 is slidably connected to the spray frame 7.

[0036] In practice, rotating the threaded rod 13 can move the limiting ring 14, thereby fixing the transmission ring 15.

[0037] See Figure 1-4 A storage box 16 is connected to the connecting frame 2. A water pump 20 is connected to one side of the storage box 16. The water pump 20 is connected to the spray pipe 10 through the installation pipe.

[0038] In practice, the storage box 16 on the connecting frame 2 is used to store soil conditioner. The water pump 20 pressurizes the conditioner in the storage box 16 through the installation pipe and delivers it to the spray pipe 10, and then sprays it through the atomizing nozzle 11.

[0039] See Figure 1-4 A stirring rack 17 is rotatably connected inside the storage tank 16, and a servo motor 18 that drives the stirring rack 17 to rotate is connected to the storage tank 16.

[0040] In practice, a stirring rack 17 is rotatably connected inside the storage tank 16. A servo motor 18 is fixed on the storage tank 16 and drives the stirring rack 17 to rotate. During the rotation, the stirring rack 17 stirs the modifier in the storage tank 16 to prevent solid particles from settling and to ensure that the modifier concentration is uniform.

[0041] Working principle: Inject soil conditioner into storage box 16 on connecting frame 2, start servo motor 18 on storage box 16 to drive mixing rack 17 inside storage box 16 to rotate, continuously stirring the conditioner to prevent solid particles from settling.

[0042] When the tractor 1 is started, the entire equipment moves forward. The two symmetrical connecting rollers 3 on the connecting frame 2 are in direct contact with the ground and roll synchronously with the terrain. This drives the coaxial connecting shaft 4 to rotate. When the connecting shaft 4 rotates, the irregularly shaped incomplete transmission gear 5 fixed on it rotates synchronously. Because its teeth are incomplete, it will intermittently mesh with the driven gear 6.

[0043] When the transmission gear 5 meshes with the driven gear 6, it drives the spray frame 7 to rotate around the connection point and adjusts the overall angle of the spray frame 7; when the transmission gear 5 disengages from the driven gear 6, the return spring 9 connected between the connecting seat 8 on the connecting frame 2 and the spray frame 7 pulls the spray frame 7 back to its initial position by the reverse elastic force generated by the stretching or compression.

[0044] According to the operational requirements, rotate the threaded rod 13 connected to the fixed seat 12 on the spray frame 7, which drives the limiting ring 14 slidably connected to the spray frame 7 to move. The limiting ring 14 limits and fixes the transmission rings 15 extending from both ends of the spray pipe 10, and at the same time adjusts the rotation resistance of the spray pipe 10. Then rotate the spray pipe 10 to adjust the orientation of the multiple atomizing nozzles 11 evenly distributed along the axis at its bottom. In conjunction with the overall angle adjustment of the spray frame 7, multi-dimensional spray coverage is achieved.

[0045] Start the water pump 20 on one side of the storage tank 16, pressurize the well-stirred amendment in the storage tank 16 through the installation pipe and deliver it to the spray pipe 10. The amendment is distributed to each atomizing nozzle 11 through the spray pipe 10, and is atomized into fine particles and sprayed evenly onto the soil surface.
