Description

Technical Field

[0001] The utility model relates to the technical field of pesticide spraying devices, and particularly relates to a pesticide spraying device for rice planting. Background Art

[0002] Rice is a cereal crop of the genus Oryza, and the representative species is rice. Rice originated in China and India. The ancestors in the Yangtze River Basin of China planted rice 7,000 years ago. The seeds of rice are called paddy. After removing the glume, the paddy becomes brown rice. After removing the rice bran layer from the brown rice, rice can be obtained. Rice is a direct cash crop, and rice is the staple food of Chinese residents. At present, the planting area of conventional rice in China is 245 million mu, and the planting area of hybrid rice is 200 million mu. When rice has pests and diseases, its yield will be seriously affected. At present, the main method to prevent pests and diseases of rice is to spray pesticides.

[0003] However, there are some defects or deficiencies in the existing pesticide spraying devices:

[0004] When the existing pesticide spraying device is in use, in order to ensure the repeated mixing of pesticides, preliminary dilution is generally required. In order to reduce the fatigue of users, when working in farmland far from home, water is usually taken from the nearby water channel by the principle of proximity. Therefore, when configuring or diluting the pesticide, the user needs to carry a dilution container or tool. After diluting the pesticide, the diluted pesticide is poured into the interior of the sprayer. When diluting and stirring the pesticide and pouring the pesticide, some pesticides are likely to splash onto the water source or soil, causing pollution to the water source or soil at the water intake, and it is also easy to cause harm to the body of the staff during the pouring process; and generally, a filter screen cover is provided at the water inlet of the existing spraying device to filter impurities in the water. However, when the existing pesticide spraying device fills water into the bucket through the filter screen cover, since the height of the filter screen cover is relatively low, the filter screen cover is likely to be blocked, resulting in water overflow. Therefore, the filter plate needs to be frequently cleaned when pouring water, which makes the water injection time longer and affects the water injection efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pesticide spraying device for rice planting to solve the above problems.

[0019] 1. The pesticide spraying device for rice planting can directly add solid drugs into the main body of the spraying tank through the arranged filtering member during use, and then inject water into the liquid medicine cavity through the medicine inlet pipe. As a result, the solid drugs and impurities in the water body can be retained in the filter screen. When the drugs are dissolved, no incompletely decomposed drugs can pass through the filter screen and enter the liquid medicine cavity, so that when spraying pesticides subsequently, no incompletely decomposed drugs and impurities in the water body will block the nozzle, ensuring the normal progress of the spraying operation and prolonging the service life of the nozzle. Moreover, the filter screen in the filtering member has sufficient height, so that the filter screen has sufficient filtering area, and water will not overflow due to the blockage of the filter screen during water injection. Therefore, during water injection, it is not necessary to frequently clean the filter screen, ensuring the water injection efficiency of the spraying tank;

[0020] 2. The pesticide spraying device for rice planting can, while stirring and mixing water and the dissolved drugs, disturb the drugs that agglomerate and form coarse agglomerates and are not fully dispersed in the filtering member, so that the drugs can be continuously and fully stirred and mixed. Therefore, it is not necessary to pre-dilute the pesticides before adding them into the main body of the spraying tank, avoiding drug splashing during the pre-dilution and pouring of pesticides, preventing pollution of the water source or soil at the water intake, and at the same time avoiding contact between the drugs and the human body during the pouring process, ensuring the health of users;

[0021] 3. After adding pesticides into the liquid medicine chamber through the pesticide bottle and emptying the liquid medicine in the pesticide bottle, the pesticide bottle can be directly thrown into the filtering component, so that the inside of the pesticide bottle can be cleaned during the subsequent mixing and stirring of the liquid medicine, and it is not easy to have the residue of the liquid medicine, ensuring the full utilization of the medicine. After the rice spraying is completed, it is convenient to take out and process the subsequent medicine bottle and impurities in the filter screen, preventing the high-concentration pesticide from remaining in the pesticide bottle and being directly discarded, resulting in environmental pollution.

[0032] As Figure 1-6 shown, a pesticide spraying device for rice planting includes: a main body 1 of a medicine spraying tank, a liquid medicine chamber 2 and a control chamber 3 arranged in the main body 1 of the medicine spraying tank, a medicine inlet pipe 4 communicated with the main body 1 of the medicine spraying tank, a sealing cover 5 threadedly installed on the medicine inlet pipe 4, a filtering member 6 arranged in the medicine inlet pipe 4 and the liquid medicine chamber 2, a stabilizing member 8 arranged below the filtering member 6 and fixed in the liquid medicine chamber 2, a mixing assembly 9 arranged in the main body 1 of the medicine spraying tank, a driving assembly 10 arranged in the control chamber 3, a water pump 11 installed in the control chamber 3 and communicated with the liquid medicine chamber 2, a connecting hose 12 with one end communicated with the liquid outlet end of the water pump 11, a medicine spraying pipe 13 communicated with the other end of the connecting hose 12, a spray head 14 installed on the medicine spraying pipe 13, and a power supply frame 15 arranged in the control chamber 3, wherein

[0033] the filtering member 6 is adapted to filter the medicine and water injected into the liquid medicine chamber 2;

[0034] the mixing assembly 9 is adapted to mix and stir the medicine and water injected into the liquid medicine chamber 2;

[0035] the stabilizing member 8 is adapted to ensure the stability of the filtering member 6 and the mixing assembly 9 during operation;

[0036] The driving assembly 10 is suitable for controlling the operation of the mixing assembly 9. When in use, the staff can transport the empty spray box body 1 to the edge of the field, then grab the sealing cover 5 to open the medicine inlet pipe 4, and then pour the powdery or liquid medicine into the filter 18, and then the user can pour the water in the canal at the edge of the field into the medicine liquid chamber 2 through the filter 18 to disperse and dissolve the medicine. The filter 6 provided can effectively filter the water body, and when in use, the coarse aggregates formed by agglomeration can be continuously decomposed and mixed with water, and no incompletely decomposed solid medicine will pass through the filter 18, avoiding impurities or incompletely dissolved medicine particles from clogging the nozzle 14 during spraying, ensuring the normal progress of the spraying operation, and extending the service life of the nozzle 14. At the same time, the bottom of the filter 18 extends to the lower end of the medicine liquid chamber 2, ensuring the filtering area, avoiding the blockage of the filter 18 during water injection and the overflow of the water body, and then during water injection, there is no need to frequently clean the filter 18, ensuring the water injection efficiency of the spray box; at the same time, in the pesticide bottle After the liquid medicine is poured out, the pesticide bottle can be directly thrown into the filter 18, so that the pesticide bottle can be cleaned in the subsequent mixing and stirring of the liquid medicine, and it is not easy to have liquid medicine residue, which ensures the full use of the medicine. After the rice spraying is completed, it is convenient for the subsequent medicine bottle to be taken out and processed together with the impurities in the filter 18, so as to prevent the high concentration of pesticides in the pesticide bottle from being easily left and directly discarded, which is easy to pollute the environment; when the medicine is dispersed in the water, the set driving component 10 can control the stirring component to work, and continuously and fully stir and mix the medicine in the filter 6 and the water in the liquid medicine chamber 2, so that the pesticide does not need to be pre-diluted before being added to the spray box body 1, and the pre-dilution of the pesticide and the splashing of the medicine during the pouring process are avoided, and the water source or soil at the water intake is prevented from being polluted, and the medicine is prevented from contacting the human body during the pouring process, which affects the health of the user; and after the liquid medicine is fully mixed, the water pump 11 works, and the liquid medicine in the liquid medicine chamber 2 can be flushed into the spraying pipe 13 through the connecting hose 12, and then sprayed out by the nozzle 14, so as to spray the rice.

[0037] Optionally, the filter member 6 includes an assembly ring 16 fixedly connected inside the medicine inlet pipe 4, a filter rack 17 with one end abutting against the upper surface of the assembly ring 16 and the other end extending to the lower end inside the liquid medicine chamber 2, a filter screen 18 installed inside the filter rack 17, a pull ring 19 hinged to the top of the filter rack 17, and a plurality of abutting blocks 20 fixed on the upper surface of the filter rack 17. During use, the provided filter screen 18 can filter the pesticides and water added into the liquid medicine chamber 2. The lower end of the filter screen 18 is placed at the lower end inside the liquid medicine chamber 2. Thus, when replenishing pesticides, solid powder pesticides will remain on the filter screen 18 to be diluted by water, and the agglomerated drugs can be continuously dispersed and diluted without pre-dilution. This can avoid the impact on the user's body when the pre-diluted pesticides are added into the spraying tank body 1, and also avoid the foaming phenomenon during the pouring of the diluted pesticides, which is not easy to observe the injection amount and is prone to liquid medicine overflow, facilitating use. Only the completely dissolved liquid medicine can enter the liquid medicine chamber 2 through the filter screen 18, thereby avoiding the entry of incompletely dissolved particles into the inside of the nozzle 14 during spraying, preventing the blockage of the nozzle 14 by the particles, ensuring the normal progress of the spraying operation, and prolonging the service life of the nozzle 14. At the same time, when taking water from the nearby field canal, impurities in the water can be filtered and isolated. Moreover, the filter screen 18 has sufficient length, and it is not easy to block the filter screen 18 during filtration, resulting in water overflow and inaccurate water injection, and also avoiding the problem of frequently cleaning the filter screen 18, which leads to the extension of the water injection efficiency. When adding and replenishing bottled liquid medicine, the emptied medicine bottle can be directly placed into the filter screen 18, so that the medicine bottle can be cleaned during the subsequent mixing and stirring of the liquid medicine, and it is not easy to have liquid medicine residue. At the same time, it is convenient to take out and dispose of the medicine bottle together with the impurities in the filter screen 18 later, preventing the random throwing of the medicine bottle from affecting the environment. When the filter screen 18 needs to be cleaned, the provided pull ring 19 facilitates lifting the filter rack 17 to drive the filter screen 18 to move out of the spraying tank body 1. The plurality of provided abutting blocks 20 can make a certain gap exist between the pull ring 19 and the top of the filter rack 17, facilitating the user to control and use the pull ring 19.

[0038] Optionally, the position stabilizing member 8 includes a support ring 21 fixed to the inner wall of the control chamber 3, a plurality of wedge-shaped guide blocks 22 fixedly arranged in an annular array on the upper surface of the support ring 21, and a positioning block 23 fixed to the inner wall of the support ring 21. During use, the provided support ring 21 can support the bottom of the filter rack 17, which can ensure that when adding water into the liquid medicine chamber 2 through the medicine inlet pipe 4, the impact damage caused by the water to the filter net 18 and the filter rack 17 can be reduced. At the same time, when the filter rack 17 is inserted into the liquid medicine chamber 2, the provided plurality of wedge-shaped guide blocks 22 can correct the position of the downward movement of the filter rack 17, ensuring that the filter rack 17 can be accurately placed on the support ring 21. And through the provided positioning block 23, positioning can be provided for the rotation of the first stirring rod 24, ensuring the stability of the rotation of the first stirring rod 24. At the same time, the first stirring rod 24 is located below the support ring 21, which is convenient for the first stirring rod 24 to stir the materials located in the filter net 18 during operation and avoid blockage of the filter net 18.

[0039] Optionally, the mixing assembly 9 includes a first stirring rod 24 and a second stirring rod 25 rotatably installed in the liquid medicine chamber 2, and a plurality of stirring blades 26 fixedly installed on the first stirring rod 24 and the second stirring rod 25;

[0040] The upper end of the first stirring rod 24 is rotatably connected to the positioning block 23, the upper end of the second stirring rod 25 is rotatably connected to the inner top of the control chamber 3, and the lower ends of both the first stirring rod 24 and the second stirring rod 25 extend into the control chamber 3. During use, the first stirring rod 24 and the second stirring rod 25 rotate, thereby controlling the plurality of stirring blades 26 to stir and mix the pesticide and water in the liquid medicine chamber 2. And the rotation directions of the first stirring rod 24 and the second stirring rod 25 are opposite, and turbulence will be generated during stirring, which can break the local equilibrium state during stirring and mixing, thereby ensuring the stirring and mixing effect. At the same time, the stirring blades 26 at the first stirring rod 24 are located below the support ring 21. When the stirring blades 26 perform stirring and mixing, the water flow can effectively stir the pesticide existing in the filter net 18, ensuring further improvement of the mixing effect of the liquid medicine.

[0041] Optionally, the driving assembly 10 includes a driving motor 27 fixed in the control chamber 3, a driving gear 28 fixed to the output end of the driving motor 27 and fixedly connected to the lower end of the first stirring rod 24, a driven gear 29 rotatably installed in the control chamber 3, a driving belt 30 meshed and sleeved on the driving gear 28 and the driven gear 29, and a transmission gear 31 fixed to the lower end of the second stirring rod 25 and meshed with the driven gear 29. When spraying pesticides, the driving motor 27 is started, the driving gear 28 is controlled to rotate, and then driven by the driving belt 30, the driven gear 29 is controlled to rotate synchronously and mesh with the transmission gear 31, so that the first stirring rod 24 and the second stirring rod 25 rotate simultaneously, and the rotation directions of the first stirring rod 24 and the second stirring rod 25 are opposite. When the first stirring and the second stirring mix the pesticides, backmixing will occur, ensuring the mixing effect of the mixing assembly 9 on the pesticides.

[0042] Optionally, a diversion groove 32 is opened at the inner bottom end of the liquid medicine chamber 2, a diversion pipe 33 is communicated with the inner bottom of the liquid medicine chamber 2, the liquid inlet end of the water pump 11 is communicated with the diversion pipe 33, an observation window 34 is arranged outside the spraying tank body 1, and a scale groove 35 is arranged on the observation window 34. When in use, when the pesticide stock in the liquid medicine chamber 2 is reduced to a certain amount, it is convenient to flow into the diversion pipe 33 through the arranged diversion groove 32 and then be controlled to be sprayed by the water pump 11, thereby effectively reducing the residue of pesticides in the liquid medicine chamber 2 and facilitating the cleaning of the subsequent spraying tank body 1. When adding water into the spraying tank body 1 before spraying pesticides, the water level line in the liquid medicine chamber 2 can be observed through the arranged observation window 34, and combined with the scale groove 35, it is convenient for users to accurately add an appropriate amount of water to ensure the mixing ratio of water and pesticides.

[0043] Optionally, one side of the spraying tank body 1 is fixedly connected with a heat dissipation backrest 36 and two adjustable straps 37. When in use, it is convenient for the staff to carry the spraying tank body 1 on the back of the user through the two arranged adjustable straps 37. By arranging the heat dissipation backrest 36, it is possible to avoid the problem that the spraying tank body 1 is close to the back of the staff during long-term labor, resulting in poor air permeability, low comfort, and easy sweating on the back.
