Technical Field

[0001] This utility model relates to the field of soil conditioner spraying technology, specifically to a soil conditioner spraying device. Background Technology

[0002] Soil improvement refers to a series of technical measures that utilize theories and technologies from multiple disciplines such as soil science, biology, and ecology to eliminate or prevent adverse factors that affect crop growth and cause soil degradation, improve soil properties, enhance soil fertility, and create favorable soil environmental conditions for crops. Although existing soil amendment spraying devices used in agricultural production can also achieve the purpose of spraying soil amendments on the soil using sprayers, most of the existing devices directly spray the soil amendments onto the soil surface, which is not conducive to the rapid dissolution of the soil amendments into the soil and thus does not achieve the goal of improving soil quality more quickly.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The hollow shaft is driven by a motor to rotate, which in turn drives the hollow cylinder to rotate, thereby driving the soil-breaking cutter head to rotate and break the soil. During soil breaking, the force between the soil-breaking cutter head and the soil provides a forward force, making it easier for workers to push the equipment. At this time, the feed pump delivers the soil conditioner from the tank to the hollow shaft. The conditioner enters the hollow cylinder from the outlet hole on the hollow shaft and then exits from the spray hole, achieving the effect of breaking the soil and spraying at the same time. This not only allows the conditioner to be sprayed directly into the deep pit formed by breaking the soil, but also further increases the contact area between the conditioner and the soil, reducing the difficulty of the conditioner's penetration and reducing the loss rate of the conditioner.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a soil conditioner spraying device, including a frame 1, a central traveling wheel 2 at the bottom center of the frame 1, a handle 15 fixedly installed at the top right end of the frame 1, a soil-breaking chamber 5 fixedly installed at the left end of the central traveling wheel 2, a hollow shaft 6 rotatably connected inside the soil-breaking chamber 5 via bearings, a hollow cylinder 7 fixedly sleeved on the outer wall of the hollow shaft 6, a liquid outlet 601 opened on the hollow shaft 6, multiple rows of soil-breaking cutters 8 fixedly installed on the outer wall of the hollow cylinder 7, multiple rows of spray holes 9 opened on the outer wall of the hollow cylinder 7, a medicine tank 3 and a feed pump 4 fixedly installed on the top of the frame 1, the output end of the feed pump 4 is connected to the hollow shaft 6 via a pipe, and the hollow shaft 6 and the pipe are connected via a rotary joint, the input end of the feed pump 4 is connected to the discharge port of the medicine tank 3, a drive component 10 is provided on the top of the frame 1, and the drive component 10 is connected to the hollow shaft 6. The transmission connection allows the handle 15 to be pulled to tilt the frame 1 when soil conditioner needs to be sprayed, thus allowing the soil-breaking cutter head 8 in the soil-breaking chamber 5 to contact the soil. The drive motor 1001 rotates the hollow shaft 6, which in turn rotates the hollow cylinder 7, which in turn rotates the soil-breaking cutter head 8 to break the soil. During soil breaking, the force between the soil-breaking cutter head 8 and the soil provides a forward force, making it easier for workers to push the equipment. At this time, the feed pump 4 delivers the conditioner from the medicine tank 3 to the hollow shaft 6. The conditioner enters the hollow cylinder 7 from the liquid outlet 601 on the hollow shaft 6 and then exits from the spray hole 9, achieving the effect of breaking the soil and spraying at the same time. It can not only spray the conditioner directly into the deep pit formed by breaking the soil, but also further increase the contact area between the conditioner and the soil, reducing the penetration difficulty of the conditioner and reducing the loss rate of the conditioner.

[0019] The drive component 10 includes a drive motor 1001 and a connecting cover 1005. Both the drive motor 1001 and the connecting cover 1005 are fixedly mounted on the top of the frame 1. A worm 1002 is fixedly mounted on the output end of the drive motor 1001. The worm 1002 meshes with a worm wheel 1003. A rotating shaft 1004 is fixedly mounted on the inner wall of the worm wheel 1003. The front and rear ends of the rotating shaft 1004 pass through the inner wall of the connecting cover 1005 through bearings. The rotating shaft 1004 is connected to the hollow shaft 6 through a pulley set. The drive motor 1001 drives the worm 1002 to rotate, which in turn drives the worm wheel 1003 to rotate. The rotation of the worm wheel 1003 drives the rotating shaft 1004 to rotate, which in turn drives the hollow shaft 6 to rotate. The transmission connection between the worm 1002 and the worm wheel 1003 increases the torque at the power output end, ensuring that there is enough force to drive the hollow cylinder 7 to rotate, so that the soil-breaking cutter head 8 can break the soil.

[0020] A protrusion is provided at the position where the soil breaking head 8 is installed on the hollow cylinder 7, and the protrusion is integrally formed with the hollow cylinder 7. The spray hole 9 corresponds one-to-one with the soil breaking head 8, which increases the strength of the connection between the hollow cylinder 7 and the soil breaking head 8, thereby avoiding the problem of breakage and deformation at the connection between the hollow cylinder 7 and the soil breaking head 8. The one-to-one correspondence between the soil breaking head 8 and the spray hole 9 can ensure that the spray hole 9 can spray the soil conditioner directly to the soil breaking point in a timely manner.

[0021] A battery 14 is fixedly installed on the top of the frame 1, and a controller 16 is fixedly installed on the handle 15. The controller 16 is electrically connected to the drive motor 1001 and the feed pump 4. The battery 14 is electrically connected to the drive motor 1001, the feed pump 4, and the controller 16.

[0022] The frame 1 is fixedly equipped with a shield 11, a shield 2 12, and a shield 3 13. The shield 11 covers the drive motor 1001, the shield 2 12 covers the rotating shaft 1004, and the shield 3 13 covers the pulley assembly. The shields cover the exposed transmission components, protect the transmission components, and also make the overall appearance more aesthetically pleasing.

[0023] A connecting frame 17 is fixedly installed at the bottom of the frame 1. An auxiliary wheel 18 is provided at the bottom of the connecting frame 17. The lowest point of the auxiliary wheel 18 is flush with the lowest point of the central traveling wheel 2. When not breaking the ground, the handle 15 can be pulled to make the frame 1 parallel. At this time, the central traveling wheel 2 and the auxiliary wheel 18 contact the ground at the same time, reducing the difficulty of pushing the cart.

[0024] Working principle: When in use, pulling the handle 15 tilts the frame 1, allowing the soil-breaking cutter head 8 in the soil-breaking chamber 5 to contact the soil. The drive motor 1001 is activated, driving the worm gear 1002 to rotate, which in turn drives the worm wheel 1003. The worm wheel 1003 rotates the shaft 1004, which in turn drives the hollow shaft 6 to rotate. The rotation of the hollow shaft 6 drives the hollow cylinder 7 to rotate, which in turn drives the soil-breaking cutter head 8 to rotate, breaking the soil. During soil breaking, the force between the soil-breaking cutter head 8 and the soil provides forward momentum, making it easier for the worker to push the equipment. At this time, the feed pump 4 delivers the soil conditioner from the medicine tank 3 to the hollow shaft 6. The conditioner enters the hollow cylinder 7 through the liquid outlet 601 on the hollow shaft 6 and then exits through the spray hole 9, achieving the effect of spraying while breaking the soil. This not only allows the conditioner to be sprayed directly into the deep pit formed by soil breaking but also further increases the contact area between the conditioner and the soil, reducing the difficulty of conditioner penetration and the loss rate.

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
