Description

Technical Field

[0001] This utility model relates to the technical field of spraying devices, and in particular to a cultivation spraying device. Background Technology

[0002] Cultivation spraying devices are mechanical equipment used in modern agriculture for the precise and efficient spraying of pesticides (such as insecticides, fungicides, herbicides, foliar fertilizers, etc.) onto crops (fruit trees, vegetables, greenhouse crops, nurseries, etc.). Their core purpose is to atomize the pesticide solution and spray it evenly onto the crops to achieve the effects of preventing and controlling pests and diseases, supplementing nutrients, or controlling growth.

[0003] In related technologies, common spraying devices come in various forms, ranging from simple hand-push sprayers to large overhead sprayers. However, their structures typically include a separate tank for premixing the pesticide solution. Powdered formulations, in particular, are prone to uneven mixing within the tank, leading to sedimentation. This not only results in inconsistent spray concentrations and affects efficacy but also causes frequent clogging of nozzles and filters, interrupting operations. Furthermore, the complex internal structure of the tank makes thorough cleaning difficult when changing pesticides, and residual pesticides can cause cross-contamination. Utility Model Content

[0005] Therefore, the purpose of this utility model is to propose a cultivation spraying device that adopts a continuous operation and instant mixing structure. It realizes the functions of mixing, liquid inlet, liquid outlet and spraying through integrated drive. It is suitable for continuous operation and significantly improves the reliability, uniformity and automation level of spraying operation.

[0006] To achieve the above objectives, this utility model proposes a cultivation spraying device, including a base plate, a spraying assembly, a first driving mechanism, and a mixing and feeding mechanism. The first driving mechanism is disposed on the base plate, the spraying assembly is disposed on the base plate and is connected to the mixing and feeding mechanism through the first driving mechanism.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The cultivation spraying device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0017] like Figure 1 - Figure 3 As shown, the cultivation spraying device of this utility model embodiment may include a base plate 1, a spraying component 2, a first driving mechanism 3, and a mixing and feeding mechanism 4.

[0018] The first drive mechanism 3 is mounted on the base plate 1, and the spraying component 2 is mounted on the base plate 1 and is connected to the mixing and feeding mechanism 4 through the first drive mechanism 3.

[0019] It should be noted that the base plate 1 described in this embodiment can stably support the spraying component 2, the first drive mechanism 3 and the mixing and feeding mechanism 4. Universal wheels are provided at the bottom corners of the base plate 1, and two handles are provided on the top of the base plate 1 for pushing the device to move.

[0020] The mixing and feeding mechanism 4 includes a receiving cylinder 41, a feeding assembly 42, and a partition 43.

[0021] The storage cylinder 41 is disposed on the base plate 1, the partition 43 is disposed inside the storage cylinder 41 and divides the storage cylinder 41 into a storage cavity 411 and a mixing cavity 412, and the feeding assembly 42 is disposed on the storage cylinder 41.

[0022] It should be noted that the bottom of the storage cylinder 41 proposed in the above embodiment is designed to be narrowed. The powder and liquid medicines are placed in the storage cavity 411, and after passing through the partition 43 into the mixing cavity 412, they are mixed and dissolved. The feeding assembly 42 is composed of a screw conveyor and a water pump. The screw conveyor is used for feeding the powder medicines, and the water pump is used for pumping the liquid medicines.

[0023] Specifically, during the actual spraying process, the relevant personnel load the powdered agent into the hopper of the screw conveyor, and the liquid agent is extracted from the storage box by connecting the water pump pipeline. It is continuously replenished during the spraying process. In the initial state, the piston 32 is located at the bottom inside the pressure cylinder 31.

[0024] In use, the first drive device 33 is driven to contract, and the piston 32 moves upward to seal against the inner wall of the pressure cylinder 31, making the bottom of the pressure cylinder 31 negative pressure. The negative pressure is then transmitted to the mixing chamber 412 through the feed pipe 34 and the first one-way valve 341. The powder and liquid medicine in the receiving chamber 411 pass through the through hole 431 and the rubber flap 432 through the partition 43, so that the powder medicine dissolves in the liquid medicine, thus achieving mixing. The medicine then passes through the feed pipe 34 into the pressure cylinder 31 for storage. The first drive device 33 is driven to press down and push the piston 32 to squeeze the mixed medicine out. The medicine enters the pressure box 21 through the discharge pipe 35 and the second one-way valve 351, and is further pressurized in the pressure box 21 before flowing into the pressure pipe 22. Finally, it is sprayed out by multiple spray heads 23 to achieve spraying.

[0025] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the partition 43 has multiple through holes 431, and a rubber valve 432 is provided inside the through holes 431.

[0026] It should be noted that the through holes 431 described in this embodiment are arranged in an array on the cross-section of the partition 43. The internal rubber valve 432 is in a closed state at room temperature. When subjected to negative pressure, the powder and liquid agents open it to achieve agent mixing.

[0027] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the spraying assembly 2 includes a pressure box 21, a pressure pipe 22, and multiple spray heads 23.

[0028] The pressure box 21 is mounted on the base plate 1, the pressure pipe 22 is movably connected to the pressure box 21, and multiple spray heads 23 are mounted on the pressure pipe 22 and connected to the pressure box 21 through the pressure pipe 22.

[0029] It should be noted that the pressure pipe 22 described in this embodiment is arranged in an inverted U-shape, and multiple spray heads 23 are arranged sequentially and at intervals along the shape of the pressure pipe 22, acting on the upper part and sides of the crop. At the same time, the pressure pipe 22 can be rotated and adjusted.

[0030] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the first drive mechanism 3 includes a pressure cylinder 31, a piston 32, a first drive device 33, a feed pipe 34, and a discharge pipe 35.

[0031] The pressure cylinder 31 is mounted on the base plate 1, the piston 32 is movably connected to the inside of the pressure cylinder 31 via the first driving device 33, the feed pipe 34 is located between the pressure cylinder 31 and the receiving cylinder 41 and is connected to the mixing chamber 412, and the discharge pipe 35 is located between the pressure cylinder 31 and the pressure box 21.

[0032] It should be noted that the first driving device 33 proposed in the above embodiment is a cylinder. A sealing silicone pad is set at the point where the cylinder passes through the pressure cylinder 31. The piston 32 slides tightly against the inner wall of the pressure cylinder 31 to realize the positive and negative pressure adjustment at the bottom of the pressure cylinder 31.

[0033] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the feed pipe 34 is equipped with a first check valve 341, and the discharge pipe 35 is equipped with a second check valve 351.

[0034] It should be noted that the first one-way valve 341 and the second one-way valve 351 described in this embodiment have the same flow direction. When the piston 32 moves upward and a negative pressure is generated at the bottom of the pressure cylinder 31, the second one-way valve 351 closes, and only the first one-way valve 341 can be opened to draw the medicine from the storage hopper through the feed pipe 34 and achieve mixing. When the piston 32 is pressed down, the bottom of the pressure cylinder 31 is in a positive pressure state, and the mixed medicine is sent to the pressure box 21 through the discharge pipe 35 and the second one-way valve 351. At the same time, the first one-way valve 341 is in a closed state.

[0035] In summary, the cultivation spraying device of this utility model adopts a continuous operation and instant-use structure. It realizes the functions of mixing, liquid inlet, liquid outlet and spraying through integrated drive. It is suitable for continuous operation and significantly improves the reliability, uniformity and automation level of spraying operation.
