Abstract

This utility model discloses a pesticide spraying device for sugar beet cultivation, including a frame with a pump motor mounted on top and a water pump mounted inside the frame. The output end of the pump motor is connected to the water pump via a belt. A material cylinder is placed on top of the frame. One horizontal end of the material cylinder has a liquid outlet connected to the water pump, and a spray pipe is connected to the water pump. The top of the material cylinder has an opening, and a connecting pipe is formed upward at the opening. In this utility model, by adding a stirring component inside the pesticide liquid cylinder and cleverly utilizing the power output shaft of the original pump motor for coaxial drive, there is no need to configure an additional independent motor or transmission mechanism.

Description

Technical Field

[0001] This utility model belongs to the field of pesticide spraying technology, specifically relating to a pesticide spraying device for sugar beet cultivation. Background Technology

[0002] With the rapid advancement of agricultural modernization, sugar beets, as an important sugar crop and cash crop, play a crucial role in increasing sugar production and ensuring market supply through large-scale cultivation. However, sugar beets are susceptible to pests such as aphids and root maggots, as well as diseases like downy mildew and powdery mildew during their growth cycle. Therefore, it is necessary to use specialized pesticide spraying equipment to apply appropriate pesticides to sugar beets to address or prevent pest infestations.

[0003] In current pesticide spraying practices, mainstream equipment typically employs a pre-prepared pesticide solution stored in a closed container, which is then sprayed via a pumping system during field application. However, because the container structure is mostly a static container, the active ingredients (such as suspension concentrates and wettable powders) gradually settle due to gravity during prolonged storage, forming a high-density sediment layer at the bottom of the container. This sedimentation phenomenon is significantly aggravated, especially under high-temperature environments or high-concentration pesticide conditions. This results in lower initial pesticide concentrations and sudden increases in concentration during spraying. Such concentration fluctuations not only reduce the pesticide's effectiveness against target pests and lead to pesticide waste, but also pose a risk of pesticide damage to beets due to localized over-application, while simultaneously increasing the environmental safety hazard of excessive pesticide residues. Utility Model Content

[0004] The purpose of this invention is to provide a pesticide spraying device for sugar beet cultivation, so as to solve the problem mentioned in the background art that existing spraying devices have internal pesticide deposits that affect the control effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pesticide spraying device for sugar beet cultivation, comprising...

[0006] The frame has a pumping motor mounted on top, and a water pump is also mounted on the inside of the frame. The output end of the pumping motor is connected to the water pump via a belt.

[0007] A material cylinder is placed on top of the vehicle frame; one horizontal end of the material cylinder has a liquid outlet, which is connected to the water pump, and the water pump is connected to a spray pipe. In use, the water pump is started by the pump motor, and the water pump draws out the liquid medicine inside the material cylinder and finally discharges it through the spray pipe, thereby achieving spraying; the top of the material cylinder has an opening, and a connecting pipe is formed upward at the opening;

[0008] It also includes a stirring assembly, which consists of a drive unit and a stirring unit, wherein

[0009] One end of the drive unit is fixed to the pumping motor via a coupling. It is worth noting that a synchronous pulley is installed on the output end of the pumping motor via a flat key. The water pump is driven by a belt fitted on the synchronous pulley. A portion of the output end of the pumping motor extends beyond the synchronous pulley, and a coupling is fitted on the extended portion to fix it to the output shaft. The stirring unit is located inside the material cylinder, and the other end of the drive unit extends into the connecting pipe and is connected to the stirring unit. The drive unit drives the stirring unit to rotate, thereby achieving the purpose of preventing the medicine solution from settling inside the material cylinder.

[0010] Preferably, the drive unit is an output shaft. One end of the output shaft is fixed to the output shaft of the pump motor via a coupling, while the other end of the output shaft extends above the connecting pipe to avoid them from colliding. This arrangement also facilitates later assembly. A lever is fixed at an equal angle at the other end of the output shaft. Part of the output shaft is located inside the connecting pipe and connected to the stirring unit. The driving unit drives the stirring unit to rotate, thereby preventing the problem of drug liquid deposition.

[0011] Preferably, the stirring part includes a connecting rod vertically arranged inside the material cylinder, with a placement ring fixedly provided at the top of the connecting rod. The connecting rod and the placement ring are fixedly connected by a columnar body to form a whole. The top of the placement ring is also fixedly provided with a lever at an equal angle. The lever rotates to move the lever. When the lever is moved, it will drive the placement ring to rotate, and then the connecting rod will also rotate with the placement ring. The placement ring overlaps the inner side of the connecting pipe opening.

[0012] Preferably, the stirring part further includes a bottom rod fixed to the bottom end of the connecting rod, a middle tube is provided inside the bottom rod, and an extension tube is provided inside the middle tube. Tension springs are fixed between the extension tube and the middle tube, and between the middle tube and the bottom rod. When the connecting rod rotates, it will drive the bottom rod to rotate synchronously. At this time, the bottom rod will generate centrifugal force during rotation. The centrifugal force will cause the middle tube to rotate out of the bottom rod, and the extension tube will rotate out of the middle tube. The extended middle tube and extension tube can increase the stirring diameter.

[0013] Preferably, when the tension spring is in its initial state, the total length of the extension tube, the middle tube, and the bottom rod does not exceed the minimum inner diameter of the connecting tube opening, thus facilitating the placement of the connecting rod, extension tube, middle tube, and bottom rod inside the connecting rod, and ensuring that the extension tube and the middle tube do not abut against the inner wall of the barrel after they are fully extended.

[0014] Preferably, a pressure cap is also fitted over the outside of the connecting pipe opening. The pressure cap has a pre-drilled slot for fitting onto the output shaft, so that the pressure cap can be fitted onto the connecting pipe opening without being obstructed by the output shaft. The pressure cap and the connecting pipe opening are fitted together, not threaded. To ensure the stability of both, the pressure cap is made of plastic material and can be fitted onto the connecting pipe opening with slight deformation. The pressure cap does not contact the output shaft or the lever.

[0015] Preferably, the barrel is further fitted with a clamp, the bottom of which is fixed to the frame, and a bearing seat is fixed to the top of the clamp. The bearing seat is fitted onto the output shaft to support the output shaft. A lithium battery is also installed inside the frame and is electrically connected to the pumping motor.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, by adding a stirring component inside the liquid spraying cylinder and cleverly utilizing the power output shaft of the existing pumping motor for coaxial drive, no additional independent motor or transmission mechanism is required. During the spraying operation, the stirring component rotates synchronously with the pumping motor, which not only effectively breaks the sedimentation trend of suspended particles in the liquid spray, but also promotes the uniform mixing of components of different densities. Furthermore, the entire stirring system adopts a modular design with a high degree of coupling with existing devices. Only simple modifications are needed to achieve technical upgrades, which reduces equipment modification costs and ensures the convenience and reliability of operation, providing an innovative paradigm for the optimization of precision agriculture equipment.

[0031] It also includes a stirring assembly, which consists of a drive unit and a stirring unit, wherein

[0032] One end of the drive unit is fixed to the pumping motor 102 via a coupling. It is worth noting that a synchronous pulley is installed on the output end of the pumping motor 102 via a flat key.

[0033] In this embodiment, preferably, the driving unit is an output shaft 103. One end of the output shaft 103 is fixed to the output shaft of the pump motor 102 via a coupling, while the other end of the output shaft 103 extends above the connecting pipe 204 to avoid them from abutting each other. This arrangement also facilitates subsequent assembly. A lever 107 is fixed at an equal angle at the other end of the output shaft 103.
