Description

Technical Field

[0001] This utility model belongs to the field of pest control technology, and in particular relates to a grassland pest control device. Background Technology

[0002] Pests and diseases refer to the abnormal pathological phenomena that occur in plants during cultivation when they are infected by harmful organisms or affected by adverse environmental conditions. These phenomena disrupt normal metabolism, causing a series of changes and damages in physiological functions and tissue structure, resulting in abnormal morphological manifestations such as wilting, rotting, spots, powdery mildew, and mosaic patterns.

[0003] Grassland pests such as grubs, wireworms, and cutworms live in the soil and feed on grass roots. They damage the root systems of grassland vegetation, causing pasture grasses to wither and die, resulting in a decrease in grassland vegetation cover and accelerating grassland degradation. According to relevant data, the area of ​​grassland affected by underground pests is increasing year by year, seriously threatening the ecological balance of grasslands and the development of animal husbandry.

[0004] Currently, the main methods for controlling underground insect pests in grasslands are chemical control and manual excavation and killing. Chemical control usually involves applying large amounts of pesticides to the soil, which not only pollutes the soil and groundwater but also kills beneficial microorganisms in the soil and damages the soil ecosystem. Manual excavation is not only extremely inefficient but also easily causes significant damage to grassland vegetation.

[0005] Therefore, developing a control device that can target underground pests in grasslands is an urgent task for researchers in this field. Utility Model Content

[0044] Example 1

[0045] See appendix Figure 1-5 As shown in the embodiments of this application, a grassland pest control device is disclosed, comprising:

[0046] The main body 1 has a flow cavity with two openings inside. In other words, the main body 1 is a cylindrical structure with two openings. Its cross-sectional shape can be rectangular, circular, elliptical, triangular or irregular, preferably rectangular. Its material is selected according to actual needs. When the main body 1 is a rectangular cylindrical structure, its bottom is provided with symmetrically arranged conical baffles, and a limiting block 101 is provided on the conical baffles.

Its rotating end is provided with a liquid storage tank arranged in a ring array. The rotating end is placed in the liquid outlet pipe and the liquid storage chamber respectively.

[0057] Liquid inlet channel 304 is located at the top of the housing 301 and passes through the housing 301 to connect with the first opening;

[0058] The liquid injection component is connected to the liquid inlet channel 304;

[0059] The control unit is a microcontroller with a timing module inside, which can periodically activate the drive device 303 and the pumping device 5, thereby enabling the agent to enter the soil periodically. The control unit is located inside the housing 301 and is electrically connected to the drive device 303.

[0060] It should be further explained that the liquid injection component includes: a bottle body 307, a receiving cavity inside the bottle body 307, and a push-button switch valve 308 at the top opening of the receiving cavity.

[0061] The push-button switch valve 308 is a combined structure, including:

[0062] The connector is fixedly connected to the bottle body 307. It has a through hole at the center and limiting grooves 3083 on both sides of the through hole. The connector has sliders arranged symmetrically on both sides.

[0063] A cover 3082 is disposed inside the connector and is centered with the through hole;

[0064] A spring is provided in a limiting groove 3083, with one end connected to a connector and the other end connected to a cover 3082, so that the cover 3082 contacts the edge of the through hole.

[0065] The liquid inlet channel 304 is provided with symmetrically arranged sliding grooves 3041, and an annular groove 3042 is provided at the bottom of the sliding grooves 3041. The liquid inlet channel 304 is provided with a first support rod 3043, and a second support rod 3044 is provided on the first support rod 3043. The first support rod 3043 and the second support rod 3044 are arranged vertically, and the top of the second support rod 3044 is located above the annular groove 3042.

[0066] One-way valve 4 is located in the flow chamber and is fixedly connected to the main body 1.

[0067] It should be noted that the one-way valve 4 is a combined structure, including:

[0068] The locking block 402 is disposed on the inner wall of the flow cavity and is fixedly connected to the main body 1.

[0069] The third movable plate 401 is arranged at an angle in the flow cavity. One end of the third movable plate 401 is hinged to the main body 1, and the other end is connected to the bottom of the locking block 402. A torsion spring is provided at the hinge point between the third movable plate 401 and the main body 1.

[0070] The air pumping device 5 is a pressurized air pump. The air pumping device 5 is located on one side of the main body 1. Its air outlet extends through the main body 1 into the flow cavity. The air outlet is located below the one-way valve 4. By injecting gas into the flow cavity, the two movable ends of the opening and closing device 2 are opened under pressure, allowing the internal liquid to flow out.

[0071] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0072] In use, a hole is dug at a preset location on the ground, or the main body 1 carrying the opening and closing device 2 is directly driven into the ground to a preset depth, so that the pumping device 5 is above the ground. Pesticide for pest control is injected into the receiving cavity of the injection unit, and then closed by pressing the switch valve 308. By inverting the injection unit, the slider in the switch valve 308 engages with the groove 3041 in the liquid inlet channel 304, sliding downwards, thereby bringing the second support component into contact with the cap 3082. At this time, the spring extends and retracts, and the pesticide enters the liquid inlet channel 304 from the receiving cavity. When the cap 3082 reaches the annular groove 3042, the bottle body 307 is rotated, causing the slider to disengage from the groove 3041, thus reducing the injection operation and allowing the pesticide to enter the storage cavity through the liquid inlet channel 304. By pre-setting the working mode of the control unit, the control unit periodically controls the drive device 303 and the pumping device 5 to operate. The actuator 303 drives the rotating end to rotate, thereby allowing the agent to enter the storage tank. As the rotating end rotates, the agent enters the outlet channel 302 and then passes through the one-way valve 4 to the opening and closing device 2. When the agent reaches the one-way valve 4, the third movable plate 401 is separated from the locking block 402 due to the weight of the agent, allowing the agent to flow down. Under the action of the torsion spring, the third movable plate 401 is reset. At this time, the pumping device 5 pumps air into the storage chamber, increasing the internal air pressure. This causes the first movable plate 201 and the second movable plate 202 to open under the pressure, allowing the agent to enter the soil with the airflow (filling the surrounding soil with the agent, thereby achieving the effect of killing or expelling). When the pressure inside the flow chamber decreases, the first movable plate 201 and the second movable plate 202 are reset under the action of the elastic element, returning to the closed state to prevent water from entering the soil. The conical structure facilitates the entry of the main body 1 into the soil.
