Technical Field
[0001] This utility model relates to the field of orchard planting equipment technology, and in particular to a self-propelled sprayer for orchards. Background Technology
[0002] When planting fruit trees, orchards will plant corresponding fruit trees according to different geographical locations. In order to ensure that the fruit trees can grow normally, appropriate pesticides need to be applied.
[0003] In the prior art, such as the self-propelled spraying vehicle disclosed in Chinese Patent Publication No. CN205392801U, there is a tractor 1. The tractor 1 has a plunger pump 2 at its front end and a medicine tank 3 with a drain outlet at the bottom on its body. The medicine tank 3 contains an infusion pipe 4 and a return pipe 5 extending outwards. The plunger pump 2 has interfaces for connecting with the infusion pipe 4 and the return pipe 5, and also an interface for connecting with a spray pipe 6. The eccentric wheel 21 of the plunger pump 2 is driven by the drive wheel 11 of the tractor 1's drive mechanism via a belt 7. This invention utilizes the tractor's built-in drive mechanism to rotate the plunger pump's eccentric wheel, eliminating the need for an additional drive unit to operate the plunger pump, thus allowing for a more compact layout. Furthermore, this invention only requires a single belt for power transmission, resulting in a very simple structure and reliable power transmission.
[0004] While the aforementioned patent achieves reliable power transmission, when spraying pesticides on fruit trees inside the orchard, the existing self-propelled sprayers can only spray the roots of the trees because the trees are tall and the buds and stamens are located on the branches. They cannot spray the buds and stamens, resulting in poor performance and thus requiring improvement. Utility Model Content
[0005] The purpose of this invention is to provide a self-propelled sprayer for orchards, which can spray pesticides on the buds and stamens of fruit trees.

[0036] Reference Figure 1-4 A self-propelled sprayer for orchards includes the following specific embodiments:
[0037] Example 1: A self-propelled sprayer for orchards includes a body 1. A rectangular cavity 26 is formed at the top of the body 1. A spray pipe 6 passes through the rectangular cavity 26 and extends to the outside of the body 1. The rectangular cavity 26 is elongated. The spray pipe 6 moves within the rectangular cavity 26. A storage bin 2 is formed inside the body 1. A first slide rail 3 is fixedly connected to one side of the inner wall of the storage bin 2. A pump frame 4 is slidably connected inside the first slide rail 3. A pulley 24 is provided at the bottom of the pump frame 4. The pump frame 4 is supported by the pulley 24 on the inner bottom wall of the storage bin 2. When the pump frame 4 moves, the pulley 24 supports the pump frame 4. The pulley 24 moves along the inner bottom wall of the storage bin 2. A pump 5 is fixedly installed inside the pump frame 4. The output end of the pump 5 is fixedly connected to the spray pipe 6. One end of the dispensing pipe 6 is equipped with an L-pipe 7. A flange 8 is installed between the dispensing pipe 6 and the L-pipe 7, and the dispensing pipe 6 and the L-pipe 7 are movably connected through the flange 8. One end of the L-pipe 7 is fixedly connected to a nozzle 9. An electric push rod 10 is fixedly installed on the outside of the machine body 1. A protective sleeve 11 is fixedly connected to the outside of the dispensing pipe 6, and the protective sleeve 11 is fixedly connected to the output end of the electric push rod 10. A vertical plate 12 is fixedly connected to the outside of the machine body 1. A fan 13 is fixedly installed inside the vertical plate 12. An air vent is opened on the outside of the vertical plate 12, and a grille 14 is fixedly connected inside the air vent. The dispensing pipe 6 is vertical and extends through a rectangular cavity 26 to the outside of the machine body 1, so that the dispensing pipe 6 can be positioned at a high position and at the same height as the buds and stamens of the fruit tree, so as to dispense the pesticide. Pipe 6 and L-pipe 7 are connected by flange 8. Pump 5 draws the pesticide solution from the storage tank 2 into the outlet pipe 6, which is then sprayed out through nozzle 9 to treat the buds and stamens of the fruit trees. During this process, electric push rod 10 drives the pump frame 4, pump 5, and outlet pipe 6 to move. Pump frame 4 slides inside the first slide rail 3, and electric push rod 10 pushes outlet pipe 6 to slide inside rectangular cavity 26, thereby adjusting the spraying position of nozzle 9 to achieve multi-position spraying of the buds and stamens of the fruit trees. When nozzle 9 sprays, fan 13 generates airflow that passes through the air vent and the outside of grille 14, thus diffusing the pesticide from nozzle 9 and ensuring the pesticide fully mixes with the fruit tree buds and stamens. This device can not only spray the buds and stamens of fruit trees, but also increase the spray coverage area and greatly improve the spraying effect. The outer side of the vertical plate 12 is fixedly connected to the second slide rail 15. The inner side of the second slide rail 15 is slidably connected to the limit ring 16. The discharge tube 6 extends into the inner side of the limit ring 16 and moves through the limit ring 16 inside the second slide rail 15. When the discharge tube 6 moves, the limit ring 16 moves inside the second slide rail 15 and extends into the inner side of the limit ring 16. The inner side of the limit ring 16 is threaded with a screw pin 17, which fixes the discharge tube 6 inside the limit ring 16, so that the discharge tube 6 can be installed inside the limit ring 16.
[0038] Example 2: A filter hopper 18 is fixedly connected to the edge inside the machine body 1. A cover plate 19 is attached to the top of the filter hopper 18. After water is injected into the storage tank 2, the medicine is put into the filter hopper 18. A latch 20 is provided on the top of the cover plate 19. The cover plate 19 is fixed to the outside of the machine body 1 by the latch 20. A motor 21 is fixedly installed on the top of the cover plate 19. A drive shaft 22 is fixedly connected to the output end of the motor 21. A stirring blade 23 is fixedly connected to the end of the drive shaft 22. The motor 21 drives the drive shaft 22 and the stirring blade 23 to rotate. The stirring blade 23 mixes the water and the medicine evenly.
[0039] Example 3: The machine body 1 is equipped with a drive device inside, and the output end of the drive device is equipped with a walking wheel 25. The drive device drives the walking wheel 25 to move, so that the walking wheel 25 drives the machine body 1 to move. The walking wheel 25 is equipped with an anti-slip layer on the outside, and anti-slip particles are provided on the outside of the anti-slip layer. The anti-slip layer and anti-slip particles increase the friction and prevent slipping during movement.
[0040] In this invention, the dispensing pipe 6 is vertical and extends through the rectangular cavity 26 to the outside of the machine body 1, allowing it to be positioned at a high level, equal to the height of the fruit tree buds and stamens. The dispensing pipe 6 and the L-pipe 7 are connected by a flange 8. The pump 5 draws the pesticide solution from the storage tank 2 into the dispensing pipe 6, which is then sprayed out through the nozzle 9, thus spraying the fruit tree buds and stamens. During this process, the electric push rod 10 drives the pump frame 4, pump 5, and dispensing pipe 6 to move. The pump frame 4 slides inside the first slide rail 3, and the electric push rod 10 pushes the dispensing pipe 6 to slide inside the rectangular cavity 26, thereby adjusting the spraying position of the nozzle 9 to achieve multi-position spraying of the fruit tree buds and stamens. When the nozzle 9 sprays, the fan 13 generates airflow, which passes through the air inlet and the grille 14. Externally, the spray nozzle 9 can diffuse the spray direction, allowing the liquid to fully contact the buds and stamens of the fruit trees. This device can not only spray the buds and stamens of the fruit trees, but also increase the spray coverage area and greatly improve the spraying effect. The spray pipe 6 extends into the inside of the limiting ring 16 and moves through the limiting ring 16 inside the second slide rail 15. When the spray pipe 6 moves, the limiting ring 16 moves inside the second slide rail 15, fixing the spray pipe 6 inside the limiting ring 16 with the screw pin 17, so that the spray pipe 6 can be installed inside the limiting ring 16. After filling the storage tank 2 with water, the liquid is poured into the filter hopper 18. The cover plate 19 is fixed to the outside of the machine body 1 by the lock 20. The motor 21 drives the drive shaft 22 and the stirring blade 23 to rotate. The stirring blade 23 mixes the water and liquid.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
