Vehicle-mounted wind-sent poison bait distributing machine

Abstract

The invention relates to a large-scale ground bait sowing machine tool, including: a sowing device composed of a medicine box, a runner, a Venturi tube, a nozzle, a centrifugal fan, a stepless variable speed motor, a generator and an electrical control component, and is characterized in that the sowing The runner in the device is fixed on the bracket, and the rotating shaft of the runner is connected with the continuously variable speed motor; on the runner is a medicine box, and a mechanical stirring device is arranged in the box; the lower end of the runner is connected with the Venturi tube, and the left end of the Venturi tube is connected with the centrifugal The outlet of the fan is connected, and the right end is connected with the nozzle; the nozzle is provided with three channels, and the cross-sectional area of ​​each channel is adjustable; the spreading device is in two sets, and the poison bait is spread to both sides of the vehicle at the same time; the spreading device is fixed on the overall welding of the vehicle On the base, the independently set generator is connected with the centrifugal fan, the stepless variable speed motor, the electrical control components and the control panel through wires. The invention utilizes a stepless variable speed motor, the spray volume can be adjusted arbitrarily according to the needs, the flow section is not easy to be blocked, the spreading is even, and the advantages are high efficiency.

Description

technical field [0001] The invention relates to a large-scale ground poison bait spreader, in particular to a vehicle-mounted wind-sent poison bait spreader, which is mainly used in the prevention and control of rodents and plant diseases and insect pests in agricultural and pastoral areas. Background technique [0002] In recent years, the country's grasslands have been plagued by rodents seriously, and the area of ​​rodent damage is about 40 million hectares. At present, the poisonous bait method is commonly used to prevent and control large-scale rodent infestation. The staff throws the poisonous bait manually, and the work efficiency is low. Moreover, the workers directly contact the poisonous bait, which poses different degrees of harm to their health. In addition, the number of pests is large, the area of ​​activity is wide, and the reproductive ability is extremely strong. Large areas must be treated at the same time to ensure the control effect. Most of the existing...

Problems solved by technology

At present, the poisonous bait method is commonly used to prevent and control large-scale rodent infestation. The staff throws the poisonous bait manually, which has low work efficiency, and the workers directly contact the poisonous bait, which poses different degrees of harm to their health.

In addition, the number of pests is large, the activity area is wide, and the reproductive ability is extremely strong. Large areas must be treated at the same time to ensure the control effect.

Most of the existing sowing technologies are aimed at small machines, and it is difficult to accurately control the amount of sowing materials, such as patent UA78098 "ORGANIC FERTILIZER BROADCASTER (organic fertilizer spreader)", RU2271647 "WORKING TOOL FOR CENTRIFUGAL FERTILIZER BROADCASTER (centrifugal fertilizer spreader)", UA61855 " CENTRIFUGALBROADCASTER (centrifugal spreader)" adopts a plate-type turntable powder discharge device. The material is thrown from the powder discharge turntable under the action of centrifugal force, and the spreading speed is limited by the limit speed of the shaft. Chinese patent ZL92236774.4 "centrifugal seed and fertilizer spreading When the cone-shaped spreading disc designed by the "device" rotates, the material is thrown out by the centrifugal force in the flow channel separated by the swept-back curved material guide plate. The Chinese patent ZL03242263.6 "spreading machine" uses the worm gear structure to manually control the spreading process, and it is automatic The degree is not high, and it is difficult to realize large-area sowing operations in a short time
