Description
Technical Field
[0001] This application relates to the technical field of sprayers, and in particular to a multi-functional self-propelled sprayer. Background Technology
[0002] With the rapid development of modern agriculture and the continuous improvement of agricultural mechanization, self-propelled sprayers have become important plant protection machinery. Sprayers are devices used to spray pesticides or water to treat or protect the land and its vegetation.
[0003] Existing sprayers use a vehicle-mounted water tank or pesticide tank, spraying pesticides or water while the vehicle is moving. Compactors also play an important role in agricultural operations, improving soil structure by compacting the soil and increasing crop resistance to lodging and yield.
[0004] Immediate compaction is required after sowing to ensure close contact between the seeds and the soil, promoting germination. Simultaneously, seedling protectants and herbicides should be sprayed. If these processes are performed separately, compaction followed by spraying will result in secondary soil compaction, negating the compaction effect; conversely, spraying before compaction may lead to pesticide runoff due to loose soil. Existing sprayers lack compaction capabilities, and performing these processes separately results in secondary soil compaction. Utility Model Content
[0005] In order to combine the pressing and spraying processes, this application provides a multi-functional self-propelled sprayer.
[0006] The multi-functional self-propelled sprayer provided in this application adopts the following technical solution:
[0007] A multi-functional self-propelled sprayer includes a vehicle body with a carrier plate fixed to the rear. The carrier plate is equipped with a water tank, a spray frame, a water delivery pipe, and a pressure accelerator. The water tank is fixed to the top of the carrier plate. One end of the spray frame is fixed to the carrier plate, and the other end is cantilevered away from the carrier plate. One end of the water delivery pipe is connected to the inside of the water tank, and the other end is mounted on the spray frame. Multiple nozzles are spaced apart on the water delivery pipe. The pressure accelerator is oscillating on the carrier plate, and the pressure accelerator oscillates towards or away from the ground.
[0008] By adopting the above technical solution, a water tank, spray frame, and compactor are integrated on the rear plate of the vehicle. The nozzles on the spray frame can spray pesticides or water, and the compactor can swing towards or away from the ground for compaction when needed. In this way, compaction and spraying can be completed simultaneously after sowing, avoiding the problems of secondary soil compaction or pesticide loss caused by separate operations. This combination of compaction and spraying improves operational efficiency and quality.
[0009] Optionally, a support frame is hinged to the carrier plate with the hinge axis arranged in the horizontal direction. The ballast is rotatably mounted on the support frame. A hydraulic cylinder is provided between the support frame and the carrier plate. One end of the hydraulic cylinder is hinged to the support frame, and the other end is hinged to the carrier plate. The hinge axes at both ends of the hydraulic cylinder are arranged in the horizontal direction.
[0010] By adopting the above technical solution, the support frame is hinged to the carrier plate, and both ends of the hydraulic cylinder are hinged to the support frame and the carrier plate respectively. The extension and retraction of the hydraulic cylinder can drive the support frame and the compactor to swing around the hinge axis, thereby adjusting the distance between the compactor and the ground, and realizing the movement of the compactor closer to or further away from the ground. This structure makes the height adjustment of the compactor convenient and flexible, adaptable to different soil conditions and operational needs, and ensures that the compaction effect meets expectations.
[0011] Optionally, the ballast is hollow inside, with a water inlet pipe connected to one end and an air outlet pipe connected to the other end. Both the water inlet pipe and the air outlet pipe are rotatably connected to the support frame to support the ballast. A water pump is installed on the carrier plate, with a water inlet pipe connected to one end of the water pump and a water tank connected to the other end. The end of the air outlet pipe away from the ballast is connected to the top of the water tank.
[0012] By adopting the above technical solution, the ballast is hollow inside, and can be connected to a water pump and water tank through a water inlet pipe, facilitating the filling of the ballast with water to increase its weight and enhance the ballasting effect. An air outlet pipe connects the ballast to the top of the water tank, allowing air to be expelled during filling and balancing the air pressure during draining. Using a water tank and water pump for filling and draining the ballast eliminates the need for additional water storage equipment, simplifies the structure, and allows for flexible adjustment of the ballast's weight to adapt to different ballasting intensity requirements.
[0013] Optionally, the support frame is provided with a rake blade, which is located at the front end of the press in the direction of travel.
[0014] By adopting the above technical solution, the rake blade is located at the front end of the rolling device's travel direction. Before the rolling device performs rolling operations, the rake blade can first break up and level the soil, break up large soil clods, and remove debris from the soil surface, so that the subsequent rolling operations can be carried out more evenly, improve the rolling effect, and also facilitate the adhesion and absorption of the spray solution.
[0015] Optionally, the support frame is provided with an adjustment assembly, which includes a protective box, a vertical rod, an adjustment rod, and two horizontal rods. One end of each horizontal rod extends into the protective box and is fixed with a first gear. The first gear is rotatably mounted inside the protective box, and the first gears on the two horizontal rods mesh with each other. The top end of the vertical rod is fixedly connected to the support frame, and the bottom end of the vertical rod is fixedly connected to the protective box. The adjustment rod is located inside the vertical rod, and its top end protrudes from the vertical rod. The bottom end of the adjustment rod extends into the protective box and is fixed with a second gear. The second gear rotates relative to the protective box and meshes with either of the first gears.
[0016] By adopting the above technical solution, in the adjustment component, rotating the adjusting rod drives the second gear to rotate. The second gear meshes with the first gear, which in turn causes the two meshing first gears to drive the crossbar to rotate, thereby adjusting the angle of the harrow blades. By adjusting the angle of the harrow blades, it is possible to adapt to different soil textures and operational needs, better utilize the harrow blades to break up and level the soil, and improve the overall operational efficiency.
[0017] Optionally, a concealed groove is provided on the adjusting rod, near the top of the adjusting rod, and the concealed groove is set along the length of the adjusting rod. A locking block and a spring are provided on the adjusting rod. The spring is located in the concealed groove, one end of the spring is fixed to the top inner wall of the concealed groove, and the other end is fixed to the locking block. The locking block is set perpendicular to the adjusting rod. A notch is provided at the top of the vertical rod, and multiple notches are provided. Adjacent notches are spaced apart circumferentially along the top end face of the vertical rod. The locking block is inserted and connected to the corresponding notch.
[0018] By adopting the above technical solution, the locking block on the adjusting rod can be inserted into the notch on the vertical rod under the action of the spring, thereby positioning the adjusting rod and preventing the rake blade angle from changing due to vibration or other reasons during operation. The multiple notches allow the adjusting rod to be fixed in different positions, thus realizing multi-level adjustment of the rake blade angle, meeting diverse operational needs, and ensuring simple and reliable operation.
[0019] Optionally, the rake blade has notches, and multiple notches are spaced apart along the edge of the rake blade.
[0020] By adopting the above technical solution, the notches on the rake blades can reduce the resistance when the rake blades come into contact with the soil, making it easier for the rake blades to cut into the soil. At the same time, when breaking up soil clods, the notches can accommodate some soil and debris, improve soil breaking efficiency, prevent soil from accumulating on the rake blades, and ensure that the rake blades work continuously and efficiently.
[0021] Optionally, the rake blade itself has a convex shape at its center.
[0022] By adopting the above technical solution, the center of the rake blade is raised. This structure allows the rake blade to generate a pushing force on the soil in all directions during operation, which enhances the soil breaking and leveling effect. At the same time, the raised part can reduce the contact area between the rake blade and the soil, increase the local pressure, make it easier to break hard soil clods, and improve the work efficiency.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. It combines the compaction and spraying processes, allowing both operations to be completed simultaneously after sowing, avoiding the problems of secondary soil compaction or pesticide loss caused by separate operations, and significantly improving operational efficiency and quality;
[0025] 2. The height and weight of the compactor are flexibly adjustable, and the angle of the rake blades can be adjusted in multiple positions, enabling the equipment to adapt to different soil conditions and operational needs, thus enhancing the equipment's versatility and practicality;
[0026] 3. The structural design of the rake blades (notch and central protrusion) improves soil breaking efficiency and leveling effect, creating favorable conditions for subsequent compaction and spraying operations, and further ensuring the quality of the operation. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0033] This application discloses a multi-functional self-propelled sprayer.
[0034] refer to Figure 1 and Figure 2 A multi-functional self-propelled sprayer includes a vehicle body with a carrier plate 1 fixed to the rear. The carrier plate 1 is equipped with a water tank 11, a spray frame 12, a water delivery pipe 13, and a pressure dam 2. The water tank 11 is fixed to the top of the carrier plate 1 and is used to store pesticide solution or water. One end of the spray frame 12 is fixed to the carrier plate 1, and the other end is cantilevered away from the carrier plate 1. One end of the water delivery pipe 13 is connected to the inside of the water tank 11, and the other end is mounted on the spray frame 12. Multiple nozzles 14 are spaced apart on the water delivery pipe 13. Liquid in the water tank 11 can be sprayed out from the nozzles 14 through the water delivery pipe 13 to achieve spraying operations. The pressure dam 2 is oscillatingly mounted on the carrier plate 1 and can swing towards or away from the ground to perform pressure operations when needed.
[0035] refer to Figure 1 and Figure 2 A support frame 3 is hinged to the carrier plate 1, with the hinge axis positioned horizontally. The ballast 2 is rotatably mounted on the support frame 3. A hydraulic cylinder 31 is installed between the support frame 3 and the carrier plate 1. One end of the hydraulic cylinder 31 is hinged to the support frame 3, and the other end is hinged to the carrier plate 1. Both hinge axes of the hydraulic cylinder 31 are positioned horizontally. By extending and retracting the hydraulic cylinder 31, the support frame 3 and the ballast 2 can be driven to swing around the hinge axis with the carrier plate 1, thereby adjusting the distance between the ballast 2 and the ground.
[0036] refer to Figure 1 and Figure 2 The ballast 2 is hollow inside, with one end connected to a water inlet pipe 21 and the other end connected to an air outlet pipe 22. Both the water inlet pipe 21 and the air outlet pipe 22 are rotatably connected to the support frame 3, and simultaneously serve to support the ballast 2. A water pump 23 is installed on the carrier plate 1. One end of the water pump 23 is connected to the water inlet pipe 21, and the other end is connected to the water tank 11. The water pump 23 can transport water from the water tank 11 to the ballast 2. The end of the air outlet pipe 22 away from the ballast 2 is connected to the top of the water tank 11. When water is added to the ballast 2, it can expel internal air, and when water is drained, it can balance the air pressure. The water pump 23 can be a bidirectional submersible axial flow pump, such as the Kaiquan GQ / GQS type or the Lanshen GWB type bidirectional submersible axial flow pump. This type of pump combines submersible motor technology with axial flow pump technology, using "S"-shaped bidirectional blades. By changing the direction of the motor rotation, forward and reverse pumping can be achieved.
[0037] refer to Figure 3 and Figure 4 A rake blade 4 is mounted on the support frame 3, located at the front end of the press 2 in the direction of travel. An adjustment assembly 5 is also mounted on the support frame 3, comprising a protective box 51, a vertical rod 52, an adjustment rod 53, and two horizontal rods 54. One end of each horizontal rod 54 extends into the protective box 51 and is fixed with a first gear 6, which rotatably rotates within the protective box 51. The first gears 6 on the two horizontal rods 54 mesh with each other. The top end of the vertical rod 52 is fixedly connected to the support frame 3, and the bottom end is fixedly connected to the protective box 51. The adjustment rod 53 is located inside the vertical rod 52, with its top end protruding from the vertical rod 52 and its bottom end extending into the protective box 51 and fixed with a second gear 7. The second gear 7 rotates relative to the protective box 51 and meshes with either of the first gears 6. Rotating the adjustment rod 53, through the meshing of the second gear 7 and the first gear 6, drives the two horizontal rods 54 to rotate, thereby adjusting the angle of the rake blade 4.
[0038] refer to Figure 3 and Figure 4The adjusting rod 53 has a concealed groove 8 located near the top of the adjusting rod 53 and along its length. The adjusting rod 53 has a locking block 81 and a spring 82. The spring 82 is located within the concealed groove 8, with one end fixed to the top inner wall of the groove 8 and the other end fixed to the locking block 81. The locking block 81 is perpendicular to the adjusting rod 53. The top of the vertical rod 52 has multiple notches 83 spaced circumferentially along the top surface of the vertical rod 52. The locking blocks 81 can be inserted into corresponding notches 83 to position the adjusting rod 53.
[0039] refer to Figure 3 The rake blade 4 has multiple notches 41, which are spaced along the edge of the rake blade 4, and the center of the rake blade 4 is raised.
[0040] The implementation principle of a multi-functional self-propelled sprayer according to this application embodiment is as follows: During operation, the vehicle body moves the carrier plate 1 across the field. The angle of the support frame 3 is adjusted via the hydraulic cylinder 31 as needed, bringing the compactor 2 closer to the ground. The water pump 23 is activated to fill the compactor 2 with water, increasing its weight and enhancing the compaction effect. Before the compactor 2 begins compaction, the rake blades 4 in front of it break up and level the soil. The angle of the rake blades 4 can be adjusted via the adjustment component 5 to adapt to different soil conditions. Simultaneously, liquid in the water tank 11 is sprayed from the nozzle 14 through the water supply pipe 13, achieving spraying. This structure enables simultaneous compaction and spraying, improving operational efficiency and quality, and allows for flexible adjustment of the various components to adapt to different operational scenarios.
[0041] 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.
