Description

Technical Field

[0001] The utility model relates to the technical field of biological control spraying, in particular to a harmful biological control spraying device. Background Art

[0002] In the process of agricultural and forestry pest control, in order to prevent pests from harming seedlings and green plants, pesticides are usually used to eliminate pests. After mixing the pesticide and water in a certain proportion, the mixed pesticide water is sprayed onto the seedlings and green plants through a spraying device, thereby preventing and controlling the pests. For example, an efficient forestry pest control sprayer with application number 202321193251.7 includes a base, a water tank is fixedly connected to one side of the upper part of the base, and a double-suction pump is fixedly connected to the bottom wall of the water tank, although it can collect and reuse the insecticide liquid that drips and deviates from the spraying range.

[0003] However, in traditional technologies or comparative documents, most of them use relatively complex reciprocating mechanisms or multi-link structures to achieve reciprocating rotation at the nozzle. However, due to the relatively complex structure, it is prone to high failure rates and difficult maintenance during use.

[0004] Moreover, in the traditional use process, the medicine required to be sprayed in different environments has different corresponding plant heights and densities due to the different environments. Therefore, different spraying heights and spraying densities are usually required for use in different environments. However, in traditional technologies or comparative documents, most of them directly install the nozzles 4a3 at corresponding heights at equal intervals, which leads to the problem of being unable to adjust the nozzle position according to the requirements of different spraying heights and spraying densities when used in different environments. Utility Model Content

[0005] The purpose of the utility model is to solve the problems that the structure is relatively complex, resulting in a high failure rate during use and difficult maintenance, and the nozzle position cannot be adjusted according to different spraying heights and spraying densities when used in different environments. A pest control spraying device is proposed.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A pest control spraying device is designed, including a vehicle body and running wheels, a medicine box is fixedly connected to the upper rear end of the vehicle body, a pump body is installed at the lower front end of the medicine box, a handrail is fixedly connected to the upper rear end of the vehicle body, a reciprocating assembly is installed on the front side of the vehicle body, and a spraying assembly is installed at the upper end of the inclined beam in the reciprocating assembly.

[0008] Preferably, the reciprocating assembly includes an oblique beam, an oblique rod, a base, a reciprocating cylinder and a support rod;

[0009] The reciprocating cylinder is fixedly connected to the front center of the lower end of the vehicle body, and the ends of the output shafts on both sides of the reciprocating cylinder are fixedly connected to support rods. The front ends of the support rods are rotatably connected to the lower part of the oblique rod through a pin shaft, and the upper ends of the oblique rods are rotatably connected to the ear plate of the oblique beam through a pin shaft, and the lower ends of the oblique beams are rotatably connected to the base through a pin shaft, and the lower ends of the bases are fixedly connected to the vehicle body.

[0010] Preferably, the front center and rear parts of the lower end of the vehicle body are both equipped with running wheels, and the center of the outer wall of the armrest is equipped with a control panel.

[0011] Preferably, the spraying assembly includes a sleeve, a slide, a spray head, a connecting rod, a positioning cylinder, a bolt and an angle block;

[0012] The multiple sleeves are respectively slidably connected to the upper outer walls of the inclined beams on both sides, the outer walls of the sleeves are tightened to the inclined beams by bolts, the slide grooves are processed on the inner walls of the inclined beams, and the upper part of the slide grooves is equidistantly slidably connected with multiple nozzles, the rear ends of the nozzles are connected to one side of the discharge port of the medicine box through a hose, and the rear outer walls of adjacent nozzles are rotatably connected by a connecting rod, the uppermost nozzle is fixedly connected to the sleeve, and a positioning cylinder is fixedly connected to the rear of the upper end of the sleeve, and the output shaft end of the positioning cylinder is fixedly connected to the end of the second upper nozzle through a corner block.

[0013] Preferably, a power supply box is fixedly installed at the center of the lower end of the vehicle body.

[0014] Preferably, rubber sleeves are sleeved on both sides of the middle portion of the outer wall of the armrest.

[0015] The utility model provides a pest control spraying device, which has the following beneficial effects:

[0016] By cooperating among the adjusting cylinder, bolts, sleeves, inclined beams and nozzles, the output shaft of the adjusting cylinder is controlled to extend and retract. Due to the use of a connecting rod connection, multiple nozzles can be driven to extend and retract at equal distances to adjust the density of the spray. Moreover, after loosening the bolts, the user can adjust the position of the sleeve on the outer wall of the inclined beam, adjust the nozzle group to the appropriate height, and then tighten the bolts to fix it. In this way, the nozzle position can be adjusted according to different spraying heights and spraying densities under different environments.

[0017] Through the coordination between the reciprocating cylinder, the base, the inclined beam and the nozzle, the output shafts on both sides of the reciprocating cylinder are controlled to move synchronously outward and inward, and then the output shaft of the reciprocating cylinder can drive the inclined beam to rotate through the connecting rod, so that the inclined beam continuously rotates back and forth around the pin shaft inside the base, thereby driving the nozzle to spray medicine within a certain range of the fan surface to achieve pest control. In this case, only a single connecting rod is used to drive the inclined beam to complete the reciprocating fan surface spraying, which effectively avoids the problem of high failure rate and difficult maintenance process during use due to the use of a more complex structure.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] Example 1:

[0026] Refer to the attached Figure 1-5: In this embodiment, a pest control spraying device includes a vehicle body 1 and running wheels 2, a medicine box 5 is fixedly connected to the upper rear end of the vehicle body 1, a pump body 10 is installed at the lower front end of the medicine box 5, a handrail 6 is fixedly connected to the upper rear end of the vehicle body 1, a reciprocating assembly 3 is installed on the front side of the vehicle body 1, a spraying assembly 4 is installed at the upper end of the inclined beam 3a1 in the reciprocating assembly 3, running wheels 2 are installed at the front center and rear side of the lower end of the vehicle body 1, a control panel 8 is installed at the center of the outer wall of the handrail 6, the control panel 8 is used to control the start and stop of the overall electronic components, a power supply box 11 is fixedly installed at the lower end center of the vehicle body 1, the power box 11 is used to supply power to the overall electronic components, and rubber sleeves 7 are sleeved on both sides of the middle of the outer wall of the handrail 6.

[0027] Refer to the attached Figure 1-5 : In this embodiment, the reciprocating assembly 3 includes an inclined beam 3a1, an inclined rod 3a2, a base 3a3, a reciprocating cylinder 3a4 and a support rod 3a5;

[0028] The reciprocating cylinder 3a4 is fixedly connected to the front center of the lower end of the vehicle body 1. The ends of the output shafts on both sides of the reciprocating cylinder 3a4 are fixedly connected to support rods 3a5. The model of the reciprocating cylinder 3a4 can be determined according to the specific usage. The front ends of the support rods 3a5 are rotatably connected to the lower part of the inclined rod 3a2 via a pin. The upper ends of the inclined rod 3a2 are rotatably connected to the ear plate of the inclined beam 3a1 via a pin. The lower ends of the inclined beam 3a1 are rotatably connected to the base 3a3 via a pin. The lower ends of the base 3a3 are fixedly connected to the vehicle body 1.

[0029] Through the coordination among the reciprocating cylinder 3a4, the base 3a3, the inclined beam 3a1 and the nozzle 4a3, the output shafts on both sides of the reciprocating cylinder 3a4 are controlled to move back and forth synchronously outward and inward, and then the output shaft of the reciprocating cylinder 3a4 can drive the inclined beam 3a1 to rotate through the connecting rod 3a2, so that the inclined beam 3a1 continuously rotates back and forth around the pin shaft inside the base 3a3, thereby driving the nozzle 4a3 to spray medicine within a certain range of the fan surface to achieve pest control. In this case, only a single connecting rod is used to drive the inclined beam 3a1 to complete the reciprocating fan surface spraying, which effectively avoids the problem of high failure rate and difficult maintenance process during use caused by the use of a more complex structure.

[0030] Refer to the attached Figure 1-5 In this embodiment, the spray assembly 4 includes a sleeve 4a1, a slide 4a2, a spray head 4a3, a connecting rod 4a4, a positioning cylinder 4a5, a bolt 4a6 and a corner block 4a7;

[0031] A plurality of sleeves 4a1 are respectively slidably connected to the upper outer walls of the inclined beam 3a1 on both sides, and the outer wall of the sleeve 4a1 is tightened against the inclined beam 3a1 by bolts 4a6. The elastic coefficient of the positioning cylinder 4a5 can be determined according to the specific usage. The slide groove 4a2 is processed on the inner wall of the inclined beam 3a1, and the upper part of the slide groove 4a2 is equidistantly slidably connected to a plurality of nozzles 4a3. The nozzles 4a3 can always maintain equidistant positions through a plurality of connecting rods 4a4. The rear ends of the nozzles 4a3 are connected to one side of the discharge port of the medicine box 5 through a hose, and the rear outer walls of adjacent nozzles 4a3 are rotatably connected by connecting rods 4a4. The uppermost nozzle 4a3 is fixedly connected to the sleeve 4a1, and a positioning cylinder 4a5 is fixedly connected to the rear end of the upper end of the sleeve 4a1. The end of the output shaft of the positioning cylinder 4a5 is fixedly connected to the end of the second upper nozzle 4a3 through an angle block 4a7.

[0032] Through the coordination among the positioning cylinder 4a5, the bolt 4a6, the sleeve 4a1, the inclined beam 3a1 and the nozzle 4a3, the output shaft of the positioning cylinder 4a5 is controlled to extend and retract, and because of the connection method of the connecting rod 4a4, multiple nozzles 4a3 can be driven to perform an equidistant extension and retraction process to adjust the density of the spraying. In addition, after loosening the bolt 4a6, the user can adjust the position of the sleeve 4a1 on the outer wall of the inclined beam 3a1, adjust the nozzle group to the appropriate height, and then tighten the bolt 4a6 to fix it. In this way, the nozzle position can be adjusted according to the requirements of different spraying heights and spraying densities under different environments.

[0033] Working principle:

[0034] When the pest control spraying device is needed, the user first opens the upper cover of the medicine box 5 and injects the liquid to be sprayed into the box. After completion, close the cover and push the device to the position where the medicine needs to be sprayed. Then, the pump body 10 is started, so that the pump body 10 drives the liquid inside the medicine box 5 through the discharge end and the hose and is finally transported to the nozzle 4a3 for spraying. At the same time, the user can control the output shafts on both sides of the reciprocating cylinder 3a4 to move back and forth synchronously outward and inward as needed, and then the output shaft of the reciprocating cylinder 3a4 can drive the inclined beam 3a1 to rotate through the connecting rod 3a2, so that the inclined beam 3a1 continuously revolves around the pin shaft inside the base 3a3. It rotates back and forth, thereby driving the nozzle 4a3 to spray medicine within a certain range of the fan to achieve the prevention and control of pests. Compared with traditional technologies or comparative documents, most of them adopt a more complex reciprocating mechanism or a multi-link structure to achieve the reciprocating rotation of the nozzle. However, due to the more complex structure, it is prone to a high failure rate and difficult maintenance process during use. Therefore, this case designs a reciprocating cylinder 3a4 as the main power source, and only uses a single connecting rod to drive the inclined beam 3a1 to complete the reciprocating fan-shaped spraying, which effectively avoids the problem of a high failure rate and difficult maintenance process during use caused by the more complex structure.

[0035] At the same time, according to the medicines required to be sprayed in different environments, the corresponding plant heights and densities are different due to the different environments. Therefore, different spraying heights and spraying densities are usually required for use in different environments. However, in traditional technologies or comparative documents, most of them directly install the nozzles 4a3 at corresponding heights at equal intervals. This leads to the problem that the nozzle position cannot be adjusted according to the requirements of different spraying heights and spraying densities when used in different environments. Therefore, a spraying assembly 4 is designed in this case. During specific use, the user can control the extension and retraction of the output shaft of the positioning cylinder 4a5 and because of the connection method of the connecting rod 4a4, multiple nozzles 4a3 can be driven to perform an equidistant extension and retraction process to adjust the spraying density. In addition, the user can adjust the position of the sleeve 4a1 on the outer wall of the inclined beam 3a1 after loosening the bolt 4a6, adjust the nozzle group to the appropriate height, and then tighten the bolt 4a6 to fix it. In this way, the nozzle position can be adjusted according to the requirements of different spraying heights and spraying densities when used in different environments.
