Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and specifically, to a cleaning device for a spray pesticide applicator. Background Technique

[0002] With the rapid development of modern agriculture, spray pesticide applicators play an increasingly important role in agricultural production due to their high efficiency and precision. The atomization technology can atomize the pesticide solution into tiny particles, increasing the coverage area and absorption efficiency of pesticides, and greatly improving the use effect of pesticides. Taking pear orchard management as an example, spray pesticide applicators are mainly used to spray acidic pesticides, such as carbendazim for controlling scab and triadimefon for treating pear rust; however, spray pesticide applicators also face some special challenges during use; due to the extremely small pesticide particles during the atomization process, they are likely to form residues on the inner wall of the pesticide spraying cylinder. These residues not only affect the effect of the next use but may also cause cross-contamination between different pesticides. Therefore, how to effectively clean and maintain the atomizing spray pesticide applicator has become an urgent problem to be solved in the current field of agricultural equipment.

[0003] These acidic pesticides are highly effective in preventing and controlling pests and diseases of pear trees. Since spray pesticide applicators usually use pesticide spraying cylinders made of plastic materials, although they have the advantages of light weight and low cost, in the face of acidic pesticides, the adsorption characteristics of the plastic surface make it easier for acidic pesticide residues to adhere firmly and are difficult to completely remove; long-term contact with acidic substances may also cause the plastic material to age or deform, affecting the service life of the equipment. Therefore, how to effectively clean and maintain the atomizing spray pesticide applicator has become an urgent problem to be solved in the current field of agricultural equipment.

[0004] For example, Chinese Patent CN208583758U discloses a cleaning device for a spray pesticide applicator, including a cylinder body. The top of the cylinder body is connected with a medicine inlet pipe. On both sides of the top of the inner cavity of the cylinder body, a first turntable and a second turntable are respectively arranged. The first turntable and the second turntable are connected by belt drive, and it can thoroughly clean the liquid medicine and sundries attached to the inner wall of the cylinder body, improving the working quality of the spray operation of the pesticide applicator. However, in the specific application process of the above cleaning device, there are the following deficiencies: First, the device fixedly sets a rotating shaft and a brush inside the cylinder body. The fixed cleaning structure is difficult to replace or repair. Once damaged, the entire pesticide spraying cylinder needs to be replaced, greatly increasing the use cost; at the same time, due to the fixed position of the rotating shaft, the angle of the brush cannot be adjusted, resulting in the inability to comprehensively and thoroughly clean the inner wall of the pesticide spraying cylinder. In particular, some dead corners are prone to accumulate acidic pesticide residues, not only reducing the cleaning efficiency but also increasing the risk of cross-contamination, affecting the use effect of pesticides, and may lead to incomplete prevention and control of pests and diseases of pear trees, with poor practicability.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0006] In view of the problems in the related art, the present utility model provides a cleaning device for a spray pesticide applicator to overcome the above-mentioned technical problems existing in the prior related art.

[0007] For this purpose, the specific technical solution adopted by the present utility model is as follows:

[0008] A cleaning device for a spray pesticide applicator includes a U-shaped mounting frame. Moving wheels are symmetrically arranged at both ends of the U-shaped mounting frame. Square support columns are arranged on both sides of the top end of the U-shaped mounting frame. Square fixing columns penetrate through the top ends of the square support columns.

A water tank is arranged at the top end of the connecting frame. A cleaning mechanism is arranged at the top end of the water tank.

[0009] Further, in order to be able to flexibly adjust the angle of the pesticide spraying cylinder during the cleaning process to ensure that the cleaning liquid can cover every corner inside the cylinder in all directions and thoroughly remove the acidic pesticide residues, the adjusting mechanism includes adjusting arms symmetrically arranged on both sides of the pesticide spraying cylinder. Adjusting rods are arranged on the inner sides of the tops of the two groups of adjusting arms. One side of the bottom end of the adjusting arm penetrates through the square fixing column and is provided with an adjusting bolt. The other side of the bottom end of the adjusting arm is provided with a connecting arm. One side of the bottom end of the connecting arm is provided with a U-shaped support frame. Semi-circular support rings matching with the pesticide spraying cylinder are symmetrically arranged on both sides of the bottom end of the U-shaped support frame. A clamping component matching with the pesticide spraying cylinder is arranged on the inner side of the top end of the U-shaped support frame.

[0010] Further, in order to be able to firmly fix pesticide spraying cylinders of different sizes and ensure the stability of the cylinder body during the cleaning process, the clamping component includes a semi-circular fixing ring arranged on the inner side of the top end of the U-shaped support frame. L-shaped connecting pieces are symmetrically arranged on the outer sides of both ends of the semi-circular fixing ring. Arc-shaped clamping plates are symmetrically arranged at both ends of the semi-circular fixing ring. A locking component is arranged on the outer side of the arc-shaped clamping plate.

[0011] Further, in order to ensure that the cleaning liquid can reach every corner inside the pesticide spraying cylinder, especially those areas that are difficult to reach, so that no matter what angle the pesticide spraying cylinder is in, it can be comprehensively and thoroughly cleaned, the cleaning mechanism includes a pump machine arranged at the top end of the water tank. A delivery hose is arranged at the top end of the pump machine. One end of the delivery hose is provided with an atomizing spray gun.

[0012] The beneficial effects of the present utility model are:

With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present utility model, a cleaning device for a spray pesticide applicator is provided.

[0027] Now, the present utility model will be further described in combination with the accompanying drawings and specific implementation manners. As Figures 1-6As shown in the figure, the cleaning device for a spray pesticide applicator according to an embodiment of the present utility model includes a U-shaped mounting frame 1. Moving wheels 2 are symmetrically arranged at both ends of the U-shaped mounting frame 1. Square support columns 3 are arranged on both sides of the top end of the U-shaped mounting frame 1. Square fixing columns 4 penetrate through the top ends of the square support columns 3 (in addition, in specific applications, the square support columns 3 and the square fixing columns 4 are fixedly connected). An adjusting mechanism 5 is arranged on the inner sides of the tops of the two groups of square fixing columns 4. A pesticide spraying cylinder 10 is arranged in the middle of the adjusting mechanism 5. A connecting frame 6 is arranged in the middle of the U-shaped mounting frame 1. An intermediate wheel 7 is arranged at the bottom end of the connecting frame 6. A water tank 8 is arranged at the top end of the connecting frame 6 (in addition, in specific applications, a liquid inlet is arranged at the top of one side of the water tank 8, and a liquid outlet is arranged at the bottom of one side of the water tank 8). A cleaning mechanism 9 is arranged at the top end of the water tank 8.

[0028] By means of the above technical solution of the present utility model, the structure of the present utility model is scientific and novel, which can effectively solve the cleaning problem faced by the spray pesticide applicator in the pear orchard, completely remove the acidic pesticide residues in the pesticide spraying cylinder 10, effectively prevent the damage of chemical reactions to the equipment, and significantly extend the service life of the pesticide applicator; at the same time, through the cooperation of the adjusting mechanism 5 and the cleaning mechanism 9, two-step cleaning with alkaline solution first and then clean water can be realized, which can not only effectively neutralize and remove acidic pesticide residues, but also ensure that no chemical substances remain in the pesticide spraying cylinder 10, significantly reducing the risk of cross-contamination and providing a strong guarantee for the safe production of the pear orchard.

[0029] In one embodiment, for the above-mentioned adjusting mechanism 5, the adjusting mechanism 5 includes adjusting arms 501 symmetrically arranged on both sides of the pesticide spraying cylinder 10. An adjusting rod 502 is arranged on the inner sides of the tops of the two groups of adjusting arms 501. An adjusting bolt 503 penetrates through one side of the bottom end of the adjusting arm 501 and the square fixing column 4 (in addition, in specific applications, the square fixing column 4, the adjusting arm 501 and the connecting arm 504 are connected by the adjusting bolt 503). A connecting arm 504 is arranged on the other side of the bottom end of the adjusting arm 501 (in addition, in specific applications, the adjusting arm 501 and the connecting arm 504 are fixedly connected). A U-shaped support frame 505 is arranged on one side of the bottom end of the connecting arm 504. Semi-circular support rings 506 matching the pesticide spraying cylinder 10 are symmetrically arranged on both sides of the bottom end of the U-shaped support frame 505. A clamping component 507 matching the pesticide spraying cylinder 10 is arranged on the inner side of the top end of the U-shaped support frame 505, so that the angle of the cylinder body can be flexibly adjusted during the cleaning process to ensure that the cleaning liquid can cover every corner inside the cylinder in all directions and completely remove acidic pesticide residues.

[0030] The working principle of the adjusting mechanism 5 is as follows: The symmetrically arranged adjusting arms 501 and the adjusting rod 502 at the top form a stable frame structure, providing all-round support for the medicine spraying cylinder 10. The design of the adjusting bolt 503 enables the operator to precisely adjust the angle of the adjusting arm 501, achieving precise adjustment of the inclination of the medicine spraying cylinder 10, and using the adjusting bolt 503 to fix the adjusting arm 501. This angle adjustment ability can ensure that the cleaning liquid evenly covers every corner of the inner wall of the medicine spraying cylinder when removing stubborn acidic pesticide residues; the combination of the connecting arm 504 and the U-shaped support frame 505 further enhances the overall structural stability and provides bottom support for the medicine spraying cylinder 10. The design of the semi-circular support ring 506 and the clamping component 507 cleverly solves the problems of fixing and quickly disassembling and assembling the medicine spraying cylinder, enabling the operator to easily install the medicine spraying cylinder in the best cleaning position and quickly remove it after the cleaning is completed.

[0031] In one embodiment, for the above-mentioned clamping component 507, the clamping component 507 includes a semi-circular fixing ring 5071 arranged inside the top end of the U-shaped support frame 505. Symmetrically arranged L-shaped connecting pieces 5072 are provided on the outer sides of both ends of the semi-circular fixing ring 5071 (moreover, in specific applications, the L-shaped connecting pieces 5072 are fixedly connected to the U-shaped support frame 505). Arc-shaped clamping plates 5073 are symmetrically arranged at both ends of the semi-circular fixing ring 5071 (moreover, in specific applications, the semi-circular fixing ring 5071 is movably connected to the arc-shaped clamping plates 5073). A locking component 5074 is arranged on the outer side of the arc-shaped clamping plate 5073. The locking component 5074 includes a triangular connecting piece 50741 arranged at one outer end of the arc-shaped clamping plate 5073 (moreover, in specific applications, the triangular connecting piece 50741 is fixedly connected to the arc-shaped clamping plate 5073). An arc-shaped locking arm 50742 is arranged at one end of the triangular connecting piece 50741 (moreover, in specific applications, the arc-shaped locking arm 50742 is movably connected to the triangular connecting piece 50741). A fixing piece 50743 is arranged on the outer side of one end of the arc-shaped locking arm 50742. A ring buckle 50744 is arranged through one end of the fixing piece 50743 (moreover, in specific applications, the fixing piece 50743 is movably connected to the ring buckle 50744). An L-shaped clamping piece 50745 is arranged at one end of the ring buckle 50744, so as to firmly fix medicine spraying cylinders of different sizes and ensure the stability of the cylinder body during the cleaning process.

[0032] The working principle of the clamping component 507 is as follows: The semi-circular fixed ring 5071 and the arc-shaped clamping plate 5073 jointly form an adjustable circular structure, which can firmly fix the medicine spraying cylinders of different sizes, ensuring the stability of the cylinder body during the cleaning process. The L-shaped connecting piece 5072 enhances the overall structural stability and provides a reliable installation foundation for the locking component 5074. In the locking component 5074, the combination of the triangular connecting piece 50741 and the arc-shaped locking arm 50742 not only provides a strong locking force but also can adapt to medicine spraying cylinders of different diameters. The settings of the fixing piece 50743, the annular buckle 50744, and the L-shaped clamping piece 50745 further enhance the locking reliability and operation convenience, and can firmly fix medicine spraying cylinders of different sizes.

[0033] In one embodiment, for the above-mentioned cleaning mechanism 9, the cleaning mechanism 9 includes a pump 901 arranged at the top of the water tank 8. A delivery hose 902 is arranged at the top of the pump 901. One end of the delivery hose 902 is provided with an atomizing spray gun 903 (in addition, in specific applications, a plurality of atomizing holes arranged in a circumferential pattern are opened on the outer side of the spray pipe of the atomizing spray gun 903 body), so as to ensure that the cleaning liquid can reach all corners inside the medicine spraying cylinder 10, especially those areas that are difficult to reach, so that no matter what angle the medicine spraying cylinder 10 is in, it can be comprehensively and thoroughly cleaned.

[0034] In addition, it should be noted that the atomizing spray gun 903 includes a spray gun body, a nozzle, and a trigger mechanism. The spray gun body is the main structure of the entire atomizing spray gun, usually made of corrosion-resistant materials, and is provided with a liquid passage inside. The nozzle is the key component of the atomizing spray gun, responsible for atomizing the liquid into fine droplets. The trigger mechanism controls the release of the liquid, allowing the operator to precisely adjust the spraying amount and spraying time. This is prior art and will not be elaborated here.

[0035] The working principle of the cleaning mechanism 9 is as follows: The pump 901 installed at the top of the water tank 8 provides power for the entire cleaning device, ensuring that the cleaning liquid can be delivered into the medicine spraying cylinder at an appropriate pressure, guaranteeing sufficient water pressure during the cleaning process to wash away and remove stubborn acidic pesticide residues; The addition of the delivery hose 902 increases the flexibility of the cleaning device. The hose can easily change its position as the angle of the adjustment mechanism 5 is adjusted, ensuring that the cleaning liquid can reach all corners of the medicine spraying cylinder, especially those hard-to-reach areas; The atomizing spray gun 903 is a key component in the cleaning process. The atomizing holes arranged in a circular pattern on its outer side can atomize the cleaning liquid into fine water droplets, forming a 360-degree spraying range. This atomizing effect can not only increase the contact area between the cleaning liquid and the inner wall of the medicine spraying cylinder, but also improve the cleaning efficiency, more effectively dissolve and wash away the acidic pesticide residues adhering to the plastic surface. Through atomization technology, the cleaning mechanism 9 can achieve efficient cleaning with less water consumption. This not only saves the cleaning cost but also reduces the amount of wastewater generated during the cleaning process, meeting the environmental protection requirements; When the operator changes the angle of the medicine spraying cylinder through the adjustment mechanism 5, the atomizing spray gun 903 can adjust its position accordingly, always maintaining the best cleaning effect. This collaborative design ensures that no matter what angle the medicine spraying cylinder 10 is in, it can be comprehensively and thoroughly cleaned.

[0036] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0037] In actual application, taking a pear orchard with an area of about 50 mu as an example, when this atomizing sprayer of the present invention is used for pest control and equipment maintenance in the orchard, after the orchard administrator completes a round of spraying of acidic pesticides (such as carbendazim), it is necessary to thoroughly clean the sprayer. First, remove the medicine spraying cylinder 10 from the sprayer and install it into the adjustment mechanism 5 of the cleaning device (the working principle of the adjustment mechanism 5 is as described above). Use the clamping component 507 of the adjustment mechanism 5 to firmly fix the medicine spraying cylinder 10 on the U-shaped support frame 505, and then adjust the angle of the adjustment arm 501 through the adjustment bolt 503 to make the medicine spraying cylinder 10 slightly inclined to ensure that the cleaning liquid can fully cover all surfaces inside the cylinder.

[0038] First cleaning (alkaline solution): The administrator injects the pre-prepared weak alkaline cleaning solution (such as sodium bicarbonate solution) into the liquid inlet of the water tank 8, starts the pump 901, and the cleaning solution is transported to the atomizing spray gun 903 through the delivery hose 902. The multiple atomizing holes of the atomizing spray gun 903 evenly spray the cleaning solution onto the inner wall of the pesticide spraying cylinder 10. During the cleaning process, the administrator slowly changes the angle of the pesticide spraying cylinder 10 through the adjusting mechanism 5 to ensure that the cleaning solution can reach all internal surfaces, especially the hard-to-reach corners. This process lasts for about 10 minutes. After the alkaline solution cleaning is completed, the administrator empties the remaining alkaline cleaning solution through the liquid outlet at the bottom of the water tank 8.

[0039] Second cleaning (rinsing with clean water): The administrator injects clean water into the water tank 8 again through the liquid inlet. Repeat the above cleaning process, this time using clean water to thoroughly rinse the pesticide spraying cylinder 10 to remove any remaining alkaline solution and loose pesticide residues. After the clean water rinsing is completed, carefully check the inside of the pesticide spraying cylinder 10 to ensure that all pesticide residues and cleaning solution have been removed. Finally, loosen the clamping assembly 507, remove the pesticide spraying cylinder 10 from the cleaning device, and place the cleaned pesticide spraying cylinder 10 in a ventilated place to dry naturally, getting it ready for the next use.

[0040] The present utility model can clean the spray pesticide machine more thoroughly than the prior art through a two-step cleaning method (first alkaline solution, then clean water). The alkaline solution can effectively neutralize and dissolve acidic pesticide residues, and the subsequent clean water rinsing ensures that no chemical substances remain in the pesticide spraying cylinder; this not only extends the service life of the equipment but also significantly reduces the risk of cross-contamination during the next use, ensuring the effect of pesticide spraying and the healthy growth of pear trees. The entire cleaning process is easy to operate, greatly improving work efficiency and bringing significant improvement to the daily management of the pear orchard.
