Abstract
Description
Technical Field
[0001] This application relates to the technical field of sprayers, and in particular to a sprayer that can be equipped with different agricultural implements. Background Technology
[0002] Traditional sprayers are mainly used for plant protection operations, while agricultural machinery sprayers are specialized equipment used in agricultural production to spray liquid pesticides and water. Their core function is to use mechanical power to apply liquid evenly and efficiently to target objects such as crops, fruit trees, lawns, and nurseries, thereby achieving agricultural operations such as pest and disease control, weed removal, nutrient supplementation, or environmental control.
[0003] The existing vehicles are equipped with liquid storage tanks that store water or pesticide solutions. The vehicles then move through the fields while spraying the liquid from the tanks.
[0004] Applying fertilizer to the fields also requires plowing. Existing sprayers have limited functionality, and when plowing is needed, the plowing machine must be replaced. Frequent equipment replacement not only increases operating costs but also leads to problems such as repeated compaction of the land and low operating efficiency. Utility Model Content
[0005] To improve the efficiency of field operations, this application provides a sprayer that can be equipped with different agricultural implements.
[0006] The sprayer that can be mounted on different agricultural implements provided in this application adopts the following technical solution: A sprayer capable of mounting various agricultural implements includes a carrier with a detachable support at its rear. The support is equipped with a liquid storage tank, a nozzle, and a blade. The liquid storage tank is fixed to the top of the support, and a water supply pipe connects the tank and the nozzle. A first vertical tube is mounted on the support, extending vertically. An electric cylinder is fixed to the first vertical tube, also extending vertically. A second vertical tube is fixed to the blade, extending vertically and having its top end fitted onto the outer wall of the first vertical tube. The second vertical tube slides along the length of the first vertical tube. The piston end of the electric cylinder is fixedly connected to the outer wall of the second vertical tube.
[0007] By adopting the above technical solution, the support at the rear of the vehicle can be combined with different agricultural implements, the liquid storage tank and nozzle can complete the spraying operation, and the electric cylinder drives the second vertical pipe to slide along the first vertical pipe, which can adjust the height of the blades to facilitate plowing operations. By integrating spraying and plowing functions on the same vehicle, there is no need to frequently change equipment, reducing operating costs and repeated land compaction, and significantly improving field operation efficiency.
[0008] Optionally, a seed box is fixed to the top of the first vertical tube, the first vertical tube is connected to the inside of the seed box, and an interval component is provided on the first vertical tube for the intermittent sliding of seeds.
[0009] By adopting the above technical solution, the seed box and the first vertical pipe work together, and with the help of the interval component, intermittent sowing of seeds can be achieved. This allows the sprayer to complete the sowing process while spraying or hoeing, further enriching the function of the equipment. It eliminates the need for an additional seeder, reduces the number of equipment replacements, and improves overall operational efficiency.
[0010] Optionally, the spacer assembly includes a housing, a drive motor, and an inner core. The drive motor is fixed to the outer wall of the housing, and its output end passes through the housing and is fixedly connected to the inner core. The inner core is rotatably disposed inside the housing. A first through hole is opened on the housing along the vertical direction, and a second through hole is opened on the inner core. The housing is inserted and fixed on the first vertical tube. The first through hole is always connected to the inside of the first vertical tube. When the second through hole coincides with the first through hole, the passage inside the first vertical tube is unobstructed.
[0011] By adopting the above technical solution, the drive motor rotates the inner core. When the second through hole on the inner core coincides with the first through hole on the outer shell, the seeds can slide down from the seed box through the first vertical tube. When they do not coincide, the seed sliding channel is closed, thus achieving intermittent seed sliding. This spacing component has a simple structure, precise control, and can adjust the seed sowing interval according to actual needs, ensuring sowing uniformity and improving sowing quality and efficiency.
[0012] Optionally, a collar is fixed on the outer wall of the first vertical tube. The collar is looped around the bracket and slides horizontally relative to the bracket eye. A positioning bolt is provided on the collar, and the positioning bolt passes through the sleeve and abuts against the bracket.
[0013] By adopting the above technical solution, the collar can slide horizontally along the support, facilitating the adjustment of the horizontal position of the first vertical tube and related components (such as seed boxes, cutters, etc.) to adapt to different operational needs and field conditions. The positioning bolts can fix the collar in the required position, ensuring the stability of the components during operation and improving the reliability and flexibility of the operation.
[0014] Optionally, the inner wall of the bottom of the seed box is inclined, and the top of the first vertical tube communicates with the inside of the seed box at the lowest point of the inclined bottom of the seed box.
[0015] By adopting the above technical solution, the bottom inner wall of the seed box is inclined, and the connection between the first vertical tube and the seed box is located at the lowest point of the inclination. This is conducive to the seeds gathering towards the connection under the action of gravity, reducing the residue of seeds in the seed box, ensuring that the seeds slide down smoothly, and improving the continuity and stability of sowing.
[0016] Optionally, a pressurizing air pump is fixed on the bracket, and an air supply pipe is connected between the pressurizing air pump and the liquid storage tank. A branch pipe is connected to the air supply pipe, and a valve is provided at the connection between the branch pipe and the air supply pipe. The end of the branch pipe away from the valve is connected to the inside of the first vertical pipe and the air outlet direction is inclined downward. The connection between the branch pipe and the first vertical pipe is located below the spacer assembly.
[0017] By adopting the above technical solution, the pressurized air pump pressurizes the liquid storage tank through the air delivery pipe, ensuring normal spraying from the nozzles; the branch pipe introduces gas into the first vertical pipe, and the downward-sloping air outlet direction can blow the seeds down, reducing seed jamming within the first vertical pipe. Valves control the opening and closing of the branch pipes, facilitating adjustment of the gas supply according to actual needs.
[0018] Optionally, a drying box is connected to the branch pipe.
[0019] By adopting the above technical solutions, the drying box can remove moisture from the gas, prevent seeds from getting damp and sticking together, ensure smooth sowing, and improve operational reliability.
[0020] Optionally, a hanging rod is fixed to the bottom of the bracket, and a pressure roller is provided on the bracket. When the pressure roller is in the stored state, it is hooked to the hanging rod. A lifting ring is fixed to the outer wall of the second vertical tube. When the pressure roller is in use, it is hooked to the lifting ring and is located on the side of the second vertical tube away from the cutter.
[0021] By adopting the above technical solution, the pressure roller is hooked to the boom when in the retracted state, without interfering with the operation of other agricultural implements; when in use, it is hooked to the ring on the second vertical tube, allowing for soil compaction after plowing, resulting in a more stable soil structure and promoting seed germination and growth. This switchable configuration enables the sprayer to compact the soil while plowing, further enhancing operational efficiency and versatility.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating multiple functions such as spraying, plowing, sowing, and soil compaction onto the vehicle, the need for frequent equipment changes is eliminated, reducing operating costs and repeated soil compaction, and significantly improving field operation efficiency; 2. The structural design of each component is reasonable. For example, the interval component allows the seeds to slide off intermittently, the collar makes it easy to adjust the horizontal position of the components, and the drying box prevents the seeds from getting damp, thus ensuring the stability and reliability of the operation. 3. The pressure roller can be switched between a stored state and a working state, which can be used to compact the land in conjunction with plowing operations without affecting the work of other agricultural implements, thus enhancing the versatility and practicality of the equipment.

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0026] This application discloses a sprayer that can be attached to different agricultural implements.
[0027] refer to Figure 1 and Figure 2 A sprayer capable of mounting various agricultural implements includes a carrier with a detachable support 1 at its rear. The support 1 is equipped with a liquid storage tank 11, a nozzle 12, and a blade 14. The liquid storage tank 11 is fixed to the top of the support 1 and is used to store liquids such as water, pesticides, or fertilizers. A water supply pipe 13 connects the liquid storage tank 11 and the nozzle 12, allowing the liquid to be transported to the nozzle 12 and then sprayed onto the field. A first vertical pipe 15 is mounted on the support 1, running vertically. An electric cylinder 17 is fixed to the first vertical pipe 15, also running vertically. A second vertical pipe 16 is fixed to the blade 14, running vertically with its top end fitted onto the outer wall of the first vertical pipe 15. The second vertical pipe 16 can slide along the length of the first vertical pipe 15. The piston end of the electric cylinder 17 is fixedly connected to the outer wall of the second vertical pipe 16. By extending and retracting the electric cylinder 17, the second vertical tube 16 can be driven to slide up and down along the first vertical tube 15, thereby adjusting the height of the cutter 14 to adapt to different plowing depth requirements. refer to Figure 2 , Figure 3 and Figure 4A seed box 2 is fixed to the top of the first vertical tube 15. The seed box 2 is used to store seeds. The first vertical tube 15 is connected to the inside of the seed box 2, allowing seeds to enter the first vertical tube 15 from the seed box 2. An intermittent seed drop interval component 3 is provided on the first vertical tube 15. The interval component 3 includes a shell 31, a drive motor 32, and an inner core 33. The drive motor 32 is fixed to the outer wall of the shell 31, and its output end passes through the shell 31 and is fixedly connected to the inner core 33. The inner core 33 is rotatably disposed inside the shell 31. A first through hole 34 is opened in the vertical direction on the shell 31, and a second through hole 35 is opened on the inner core 33. The shell 31 is inserted and fixed on the first vertical tube 15, and the first through hole 34 is always connected to the inside of the first vertical tube 15. When the drive motor 32 drives the inner core 33 to rotate, causing the second through hole 35 to coincide with the first through hole 34, the internal passage of the first vertical tube 15 is unobstructed, and the seeds can enter the first vertical tube 15 from the seed box 2 through the first through hole 34 and the second through hole 35 and slide down; when the second through hole 35 does not coincide with the first through hole 34, the internal passage of the first vertical tube 15 is closed, and the seeds stop sliding down, thereby realizing intermittent sowing of seeds. refer to Figure 2 A collar 4 is fixed to the outer wall of the first vertical tube 15. The collar 4 is fitted onto the bracket 1 and can slide horizontally relative to the bracket 1. A positioning bolt 41 is provided on the collar 4, which passes through the collar 4 and abuts against the bracket 1. By sliding the collar 4, the first vertical tube 15 and related components such as the seed box 2 and the cutter 14 can be moved horizontally. After adjusting to a suitable position, tightening the positioning bolt 41 will fix the collar 4 to the bracket 1, ensuring the stability of the component position during operation. The bottom inner wall of the seed box 2 is inclined, which is not shown in the figure here. The top of the first vertical tube 15 and the connection point with the inside of the seed box 2 are located at the lowest point of the inclined bottom of the seed box 2. This design is conducive to the seeds gathering towards the connection point under the action of gravity, reducing the residue of seeds in the seed box 2, and ensuring that the seeds can smoothly enter the first vertical tube 15. refer to Figure 2 and Figure 3A pressurizing air pump 5 is fixed on the bracket 1. An air supply pipe 51 connects the pressurizing air pump 5 to the liquid storage tank 11. The gas generated by the pressurizing air pump 5 enters the liquid storage tank 11 through the air supply pipe 51, pressurizing the liquid inside and ensuring it can be smoothly sprayed from the nozzle 12 through the water supply pipe 13. A branch pipe 52 is connected to the air supply pipe 51. A valve 53 is installed at the connection between the branch pipe 52 and the air supply pipe 51, allowing control of the opening and closing of the branch pipe 52. The end of the branch pipe 52 away from the valve 53 is connected to the interior of the first vertical pipe 15, with the air outlet angled downwards. The connection between the branch pipe 52 and the first vertical pipe 15 is located below the spacer assembly 3. The gas entering the first vertical pipe 15 from the branch pipe 52 can propel the seeds downwards, reducing seed jamming within the first vertical pipe 15. A drying box 6 is connected to the branch pipe 52, containing a desiccant to remove moisture from the gas and prevent seeds from becoming damp and sticking together. refer to Figure 1 and Figure 2 The support 1 has a hanging rod 71 fixed at the bottom and a pressure roller 7 on it. When the pressure roller 7 is in the stored state, it is hooked to the hanging rod 71. At this time, the pressure roller 7 is suspended and does not affect the operation of other agricultural implements. The second vertical tube 16 has a hanging ring 72 fixed on its outer wall. When the pressure roller 7 is in use, it is removed from the hanging rod 71 and hooked to the hanging ring 72. The pressure roller 7 is located on the side of the second vertical tube 16 away from the blade 14. After the blade 14 plows the land, the pressure roller 7 can compact the land, making the soil structure more stable and conducive to seed germination and growth.
[0028] The implementation principle of a sprayer capable of mounting different agricultural implements according to an embodiment of this application is as follows: During operation, the carrier moves the support 1 across the field. The height of the blades 14 is adjusted via the electric cylinder 17 to plow the land according to operational needs. Simultaneously, liquid in the storage tank 11 is sprayed from the nozzle 12 through the water delivery pipe 13 under the action of the pressurized air pump 5, completing the spraying operation. When sowing is required, the drive motor 32 rotates the inner core 33, causing seeds to intermittently slide from the seed box 2 through the first vertical pipe 15 into the field via the spacer assembly 3. The air introduced through the branch pipe 52 reduces seed jamming. If soil compaction is required, the pressure roller 7 is hung on the hanging ring 72 and compacts the plowed land as the carrier moves. Through the integration of multiple functions, efficient field operations are achieved.
[0029] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
