Description

Technical Field

[0001] This utility model belongs to the field of tobacco planting technology, and specifically relates to a device for quantitative application of pesticides to tobacco plants through holes. Background Technology

[0002] Tobacco cultivation is an important economic crop in my country, requiring multiple applications of fertilizers and pesticides to ensure yield and quality. Precise application of pesticides to the planting holes is crucial for healthy tobacco growth. Traditional methods rely on manual application of pesticides to each hole, which is labor-intensive and difficult to control precisely, often resulting in uneven pesticide application, wasting resources and negatively impacting tobacco growth.

[0003] With the improvement of agricultural mechanization, some mechanized pesticide application equipment has appeared on the market. However, these devices generally have problems such as complex structure, high cost, and difficult maintenance. Existing small tobacco pesticide application devices mainly use dripping, spraying, or gravity-feeding methods for application. These methods are usually slow and inefficient, and it is difficult to accurately control the amount of pesticide applied to each hole.

[0004] Meanwhile, many pesticide application devices are prone to problems such as pesticide clumping and pipe blockage during use, requiring frequent shutdowns for cleaning and affecting work efficiency. In addition, existing pesticide application devices struggle to maintain a mixed state of the pesticide, easily forming sediment in the container, which leads to inconsistent pesticide concentrations, affecting the application effect and failing to guarantee the uniformity of tobacco growth. Utility Model Content

[0005] In view of this, the present invention provides a tobacco orifice quantitative application device, which can solve the problem of uneven application of tobacco by existing orifice application devices, resulting in poor application effect.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a tobacco metering device, which includes a spraying cylinder, a support frame, and multiple sets of dispensing pipes. The dispensing pipes are arranged in a ring array at the bottom of the spraying cylinder. The inside of the spraying cylinder is connected to the multiple sets of dispensing pipes. A sealing flap is provided inside the dispensing pipe. An electric pressure rod is provided at the top of the spraying cylinder. The output rod of the electric pressure rod passes through the top of the spraying cylinder and is fixedly connected to a baffle. The baffle is in close contact with the inner wall of the spraying cylinder through a rubber stopper. A stirring mechanism is provided at the bottom of the inside of the spraying cylinder. The stirring mechanism includes a motor, a shaft seat, and a stirring rod.

[0008] The technical advantages of this utility model for a quantitative tobacco planting device are as follows: A planting cylinder is used to store the pesticide solution. An electric pressure rod acts as a power source, driving a baffle and rubber stopper to press downwards against the inner wall of the planting cylinder, forcing the pesticide through the sealing flap and out through the discharge tube into the corresponding tobacco planting hole. Multiple discharge tubes arranged in a ring array allow the pesticide solution to flow out from multiple locations, achieving uniform quantitative application. A sealing flap controls the flow of the pesticide solution and prevents leakage. A stirring mechanism prevents sediment formation at the bottom of the pesticide solution, maintaining uniformity and improving the application effect while preventing uneven pesticide concentration.

[0019] Furthermore, the sealing flap has an X-shaped opening for allowing the liquid medicine to be squeezed out through the dispensing tube.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting an X-shaped opening to control the outflow of the liquid, the liquid is prevented from leaking when no application is being made, and the X-shaped opening opens to squeeze out the liquid when application is being made.

[0021] Furthermore, the motor is fixedly installed at the bottom of the lower cylinder, the output shaft of the lower cylinder is fixedly connected to the stirring rod, and multiple sets of cylindrical stirring strips are arranged around the stirring rod.

[0035] In use, the motor 18 is started to drive the stirring rod 20 to rotate, and the stirring strip on the stirring rod 20 is used to stir the liquid medicine to make the liquid medicine fully mixed and uniform. By starting the electric pressure rod 15, the output rod of the electric pressure rod 15 is slowly pushed down, and the baffle 16 fixedly connected to the output rod moves down accordingly. Since the baffle 16 is in close contact with the inner wall of the application cylinder 10 through the rubber stopper 17, the liquid medicine in the application cylinder 10 is under pressure as the baffle 16 moves down. Under the action of pressure, the X-shaped opening on the sealing valve 14 inside the application tube 12 opens, and the liquid medicine is squeezed out from the application tube 12. By controlling the stroke of the output rod of the electric pressure rod 15, the amount of medicine applied can be precisely controlled to achieve quantitative application of medicine to the hole.

[0036] In the above technical solution, the application cylinder 10 includes an upper cylinder 101 and a lower cylinder 102.

[0038] Furthermore, in the above technical solution, the upper cylinder 101 and the lower cylinder 102 are fixedly connected by a locking block structure, which includes a bottom boss of the upper cylinder 101, a locking block 13 on the periphery, and a locking groove at the top of the lower cylinder 102.

[0039] Furthermore, in the above technical solution, a slot is provided at the position of the locking block 13 corresponding to the slot, and the locking block 13 cooperates with the slot to fix and lock the upper cylinder 101 and the lower cylinder 102.

[0040] Furthermore, in the above technical solution, a sealing gasket is provided between the card slot and the locking block 13, and a mobile power supply is fixedly provided on the outer side of the upper cylinder 101.

[0041] The electric pressure rod 15 and the motor 18 are electrically connected to a mobile power supply via external wiring.

[0044] Furthermore, in the above technical solution, the stirring rod 20 and the shaft seat 19 are rotatably connected by a bearing, and the bottom of the shaft seat 19 is fixedly connected to the inner surface of the lower cylinder 102.

[0045] Furthermore, in the above technical solution, the outer side of the application cylinder 10 is movably connected to the support frame 11 via a slider.

The handle 111 is fixedly provided on the top or side edge of both sides of the support frame 11.

[0047] When it is necessary to replenish the pesticide solution inside the application cylinder 10, lift the application cylinder 10 upward along the slides on both sides of the support frame 11, flip it over along the widened slide so that the lower cylinder 102 faces upward, disassemble the lower cylinder 102 from the upper cylinder 101, rotate the lower cylinder 102 to one side so that the locking block 13 rotates to the slot position and disengages from the slot, then add pesticide solution into the upper cylinder 101. After replenishment, put the lower cylinder 102 back into the upper cylinder 101, and then move the application cylinder 10 to the application position through the slide.

[0048] Specifically, the principle of this utility model is as follows: In use, the motor 18 is started to drive the stirring rod 20 to rotate, and the stirring strip on the stirring rod 20 is used to stir the liquid medicine to make the liquid medicine fully mixed and uniform. By starting the electric pressure rod 15, the output rod of the electric pressure rod 15 is slowly pushed downward, and the baffle 16 fixedly connected to the output rod moves downward accordingly.

Under the action of pressure, the X-shaped opening on the sealing petiole 14 inside the application tube 12 opens, and the liquid medicine is squeezed out from the application tube 12. By controlling the stroke of the output rod of the electric pressure rod 15, the amount of medicine applied is precisely controlled, and quantitative application of medicine to the hole is achieved.
