Description

Technical Field

[0001] The utility model relates to the field of agricultural equipment, in particular to a sprayer used for coating fruits before harvesting. Background Art

[0002] The coating can protect the fruit, reduce water evaporation and reduce the damage of pests and diseases, which helps to maintain the freshness of the fruit and prolong its storage time. In the existing patent application with application number CN201921803615.2, a four-nozzle single-fruit sprayer for pre-harvest fruit coating is proposed. Although it realizes the advantages of modern electromechanical combination, it can spray the viscous film liquid on the hanging fruit, which is convenient and fast, and improves efficiency. However, when wrapping the fruit, its spherical body is easy to wrap the leaves close to the fruit together, so that when its nozzle sprays the film on the fruit, the film liquid is easily blocked by the leaves, which easily causes the problem of incomplete spraying of the fruit, which will reduce the effect of spraying the film on the fruit, so it needs to be improved.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a sprayer used for coating fruits before harvesting includes a hand-held rod 1, a spray container 5 and a spray head 9. The spray container 5 is fixedly installed at the lower end of the hand-held rod 1. The spray container 5 and the spray head 9 are connected by a main pipe 6 and a branch pipe 10. The hand-held rod 1 is a hollow structure. The main pipe 6 is located in the hand-held rod 1. The branch pipe 10 passes through the wall of the hand-held rod 1 and is fixedly connected to the main pipe 6.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a mounting ball 2 is installed at the upper end of the hand-held rod 1, and the mounting ball 2 is composed of a sphere 7 and a mounting ring 8. The mounting ring 8 is fixedly installed at the upper end of the sphere 7, and the nozzle 9 is fixedly installed on the sphere 7. A mounting hole 11 is opened on the mounting ring 8, and the mounting hole 11 penetrates the mounting ring 8 inside and outside. A fixed structure 4 is movably installed on the mounting ring 8, and the fixed structure 4 is composed of a half ring 15, an annular spring 17, a connecting plate 18, a base rod 20 and a baffle 21. There are two half rings 15 and they are symmetrically arranged. The annular spring 17 is installed on the two The connecting plates 18 are arranged in the half rings 15, and are respectively fixedly mounted on the upper ends of the two half rings 15. The base rods 20 are arranged in the half rings 15, and are respectively fixedly mounted on the inner walls of the two half rings 15. The baffles 21 are arranged in the inner ends of the two base rods 20. The two half rings 15 are sleeved on the mounting ring 8. The outer wall of the half ring 15 is provided with an arc groove 16. The annular spring 17 is installed in the arc groove 16. The base rod 20 is movably installed in the mounting hole 11. The connecting plate 18 is located on the outer side of the base ring 12. Through groove 19, the upper end of the mounting ring 8 is equipped with a blocking structure 3 through a fixed structure 4, and the blocking structure 3 is composed of a base ring 12, blocking bristles 13 and a protrusion 14. The blocking bristles 13 are fixedly mounted on the inner wall of the base ring 12, and the protrusion 14 is fixedly mounted on the outer wall of the base ring 12. The base ring 12 is located at the upper end of the mounting ring 8, and the protrusion 14 is inserted into the through groove 19. By setting the mounting ball 2 and setting the blocking structure 3 on the mounting ball 2, when spraying the coating on the fruit, the fruit can enter the mounting ball 2 through the blocking structure 3. At this time, the blocking bristles 13 on the blocking structure 3 can block the leaves around the fruit, thereby preventing the leaves from entering the mounting ball 2 together with the fruit, and further preventing the film liquid from being blocked by the leaves when the fruit is sprayed with the coating. Finally, the fruit can be fully sprayed with the coating, so that the effect of spraying the coating on the fruit is better. By setting the fixed structure 4, when the blocking bristles 13 are deformed, thereby causing the effect of blocking the leaves to deteriorate, the blocking structure 3 can be easily disassembled and replaced quickly.

[0021] It should be noted that the utility model is a sprayer used for coating fruits before they are harvested. When spraying the fruits, the hand-held rod 1 can be picked up to move the mounting ball 2 toward the fruits that need to be coated, so that the fruits passively pass through the blocking structure 3 and enter the sphere 7 on the mounting ball 2. During this process, the blocking bristles 13 can block the leaves around the fruits, thereby preventing the leaves from entering the sphere 7 along with the fruits. Then the spray container 5 can be started to spray the fruits in the sphere 7. During this process, the pump on the spray container 5 will pump the film liquid into the nozzle 9 through the main pipe 6 and the branch pipe 10. Finally, the film liquid will be sprayed out from the nozzle 9 to be sprayed onto the surface of the fruits. When the fruits are sprayed, the sprayer is moved to When the bristles 13 are deformed, the effect of blocking leaves is deteriorated, and the blocking structure 3 can be replaced by first pulling the two half rings 15 on the fixing structure 4 so that the two half rings 15 are separated from each other. At this time, the annular spring 17 will be stretched and deformed. When the projection 14 on the blocking structure 3 is passively moved out of the through groove 19, the fixing of the blocking structure 3 is released, and then it can be removed from the upper end of the mounting ring 8. Finally, a new blocking structure 3 is installed on the upper end of the mounting ring 8, and then under the elastic force of the annular spring 17, the connecting plate 18 is sleeved on the projection 14 through the through groove 19. At this time, the replacement of the blocking structure 3 is completed.
