Description

Technical Field

[0001] This utility model belongs to the field of sprayer technology, and relates to a backpack-type powered sprayer. Background Technology

[0002] Backpack-mounted powered sprayers are widely used in agriculture for spraying pesticides on plants.

[0003] A search revealed a backpack-type powered sprayer disclosed in publication number "CN207951795U". This backpack-type powered sprayer includes a base, a gasoline engine, a water pump connected to the gasoline engine, and a partition located at the edge of the base. The water pump has an inlet and an outlet. The inlet is connected to a storage tank, and the outlet is connected to a distribution pipe. A shoulder strap is provided on the side of the partition facing away from the gasoline engine. This sprayer has the advantages of allowing spraying without holding the distribution pipe, high spraying efficiency, good shock absorption for the gasoline engine, good heat insulation, and convenient waste discharge.

[0004] During the use of the above-mentioned sprayer, we found that the medicine tank and the sprayer's fuel tank are designed separately. This separate design of the fuel tank increases the space occupied by the sprayer. In order to achieve a compact design, we designed a backpack-type powered sprayer to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a backpack-mounted powered sprayer to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: a backpack-type powered sprayer, including a base, a gasoline sprayer body fixedly installed at the middle of the top of the base, a support column fixedly installed on one side of the top of the base, a medicine tank fixedly installed on the top of the support column, an octagonal groove opened on the front of the medicine tank, an oil can of a suitable size connected to the inner strip of the octagonal groove, and a fixing component provided between the oil can and the medicine tank.

[0007] In the aforementioned backpack-type powered sprayer, the fixing component includes a rotating block and a threaded rod. A circular groove is provided at the center of the oil can, and a threaded rod communicating with the outside is threadedly connected inside the circular groove. A threaded hole adapted to the threaded rod is provided at the bottom of the octagonal groove, and the threaded rod is threadedly connected to the threaded hole.

[0008] In the aforementioned backpack-type powered sprayer, a rotating block is fixedly connected to the other end of the threaded rod. The rotating block is placed inside a circular groove, and the size of the rotating block is smaller than the size of the circular groove.

[0009] In the aforementioned backpack-type power sprayer, an oil outlet pipe is fixedly provided at the bottom of the oil can, and the oil outlet pipe is fixedly connected to the oil inlet end of the gasoline sprayer body.

[0010] In the aforementioned backpack-type powered sprayer, an inclined oil injection pipe is fixedly installed on the top of the oil can, and a sealing cap is threadedly connected to the top of the oil injection pipe.

[0011] In the aforementioned backpack-type powered sprayer, the top of the medicine tank is threaded with a lid, and both sides of the medicine tank are fixedly equipped with shoulder strap buckles. The top of the front of the medicine tank is fixedly marked with a box label.

[0012] Compared with the prior art, the advantages of this backpack-type power sprayer are as follows: by opening an octagonal groove on the front of the medicine tank and integrating the oil can of the gasoline sprayer inside the octagonal groove and fixing it with a fixing component, the space occupied is reduced on the one hand, and the oil can is fixed inside the octagonal groove, which can effectively prevent the gasoline from vibrating when the power is started and the fluctuation problem when the operator carries it on their back.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-3 As shown, the present invention is a backpack-type powered sprayer, including a base 1, a gasoline sprayer body 3 fixedly installed at the middle of the top of the base 1, a support column 2 fixedly installed on one side of the top of the base 1, a medicine tank 4 fixedly installed on the top of the support column 2, an octagonal groove 6 opened on the front of the medicine tank 4, an oil can 7 of a suitable size connected to the inner strip of the octagonal groove 6, and a fixing component is provided between the oil can 7 and the medicine tank 4.

[0019] Specifically, by opening an octagonal groove 6 on the front of the medicine tank 4 and integrating the gasoline sprayer's oil can 7 inside the octagonal groove 6, and fixing it with a fixing component, the space occupied is reduced on the one hand, and on the other hand, the oil can 7 is fixed inside the octagonal groove 6, which can effectively prevent the gasoline from vibrating when the engine is started and the fluctuation problem when the operator is carrying it.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention is a backpack-type power sprayer. The fixing components include a rotating block 10 and a threaded rod 12. A circular groove 9 is provided at the center of the oil can 7. The threaded rod 12, which communicates with the outside, is threadedly connected inside the circular groove 9. A threaded hole 11, which is adapted to the threaded rod 12, is provided at the bottom of the octagonal groove 6. The threaded rod 12 is threadedly connected to the threaded hole 11.

[0021] The other end of the threaded rod 12 is fixedly connected to a rotating block 10, which is placed inside the circular groove 9, and the size of the rotating block 10 is smaller than the size of the circular groove 9.

[0022] Specifically, the rotating block 10 drives the threaded rod 12 to rotate, and the threaded rod 12 is threadedly connected to the threaded hole 11, which makes it easy to fix the oil can 7 inside the octagonal groove 6.

[0023] An oil outlet pipe is fixedly installed at the bottom of the oil can 7, and the oil outlet pipe is fixedly connected to the oil inlet end of the gasoline sprayer body 3.

[0024] An inclined oil filling pipe 8 is fixedly installed on the top of the oil can 7, and a sealing cap is threadedly connected to the top of the oil filling pipe 8.

[0025] Specifically, the inclined oil filling pipe 8 facilitates oil filling of the oil can 7, avoiding the oil filling of the oil can 7 being affected by the oil can 7 being fixed inside the octagonal groove 6.

[0026] The top of the medicine barrel 4 is threaded with a lid, and both sides of the medicine barrel 4 are fixedly installed with strap buckles 13. The top of the front of the medicine barrel 4 is fixedly marked with a box mark 5.

[0027] Specifically, the strap fastening buckle 13 facilitates the assembly of the strap and makes it convenient for operators to wear the strap during use.

[0028] In practice, when it is necessary to assemble the oil can 7 and the medicine barrel 4, first press the oil can 7 into the octagonal groove 6 on the front of the medicine barrel 4. Then, manually rotate the rotating block 10. The rotating block 10 drives the threaded rod 12 to rotate, so that one end of the threaded rod 12 rotates into the threaded hole 11 at the bottom of the octagonal groove 6. This makes it easier to fix the oil can 7 inside the octagonal groove 6. During use, on the one hand, it reduces the space occupied by the oil can 7 and the medicine barrel 4 when placed separately. On the other hand, fixing the oil can 7 inside the octagonal groove 6 can effectively prevent the vibration of gasoline when the engine is started and the fluctuation problem when the operator carries it.

[0029] It should be noted that the specific working principle of the backpack sprayer has been disclosed in detail in the announcement number "CN207951795U", and will not be elaborated further in this application.
