Description

 The invention relates to the protection of plants, in particular to devices for laying out toxic baits against harmful rodents, and can be used in agriculture, farming, forestry and communal services and other areas where control over the number of harmful rodents is necessary.

A device for a shoulder-mounted manual spreader of grain bait for rodent control (1), containing an elongated reservoir with a lid and a shoulder strap. The tank is rigidly connected to a fixed tubular tip. When moving from the reservoir to the tip, a metering device is mounted, which is a plate valve, resting on one edge on the extended part of the tip and the other edge rigidly connected to the spring-loaded handle, which rotates 90 ^o , opening the outlet for the loose grain bait to the tubular tip, and then turning to its original position under the action of a spring, the valve closes the bait outlet from the tank.

 However, the known device has disadvantages in that it is necessary to manipulate the whole device (its mass in the loaded state of 6 kg) during operation due to the rigidity of its structure. In addition, the grains falling between the valve and the protrusion for its support inside the tip do not allow to immediately stop the rash of the bait, which worsens the dosage regimen. In the aggregate, the disadvantages lead to the fact that the device does not provide a strict introduction of rodenticidal bait into holes, but serves to scatter it on the surface of the soil, which does not meet modern environmental requirements.

 Closest to the proposed in its technical essence, adopted for the prototype, is a device for dispensing poisoned baits (2), containing a reservoir, a rod with a handle, a spring and a guide tube with a limiter, rigidly connected to the bottom of the tank. The rod in the lower part has a recess, which, being in the tank, is filled with bait. Pressure on the handle, overcoming the resistance of the spring, moves the recess with the bait through the bottom hole into the guide tube, from where the bait pours out.

 However, this device also has drawbacks in that during operation the entire device must be kept on weight, which makes this work unnecessarily time-consuming and does not allow the tank to be sufficiently enlarged in the interests of production technology. This disadvantage arises because the tank and the metering device are mounted rigidly. In addition, the lack of a lid at the reservoir creates a condition under which the device working can inhale the toxic fumes of the preparation.

 The technical problem solved by the invention is to increase the accuracy of dosing, increase labor productivity and reduce the sanitary and environmental hazards of rodenticidal treatments.

 This goal is achieved by the fact that the rodenticidal knapsack apparatus is made in the form of movably connected elements consisting of a tank for toxic bait with two shoulder straps (3) for carrying behind the shaft of the cultivator, a guide cylinder with a metering piston and a connecting flexible hose with an exhaust valve.

 The novelty of the submitted application lies in the fact that the use of the movable structure of the knapsack rodenticidal apparatus allows to increase the capacity of the bait tank, to ensure the accuracy of its dosage.

 The drawing shows a rodenticidal knapsack apparatus.

 The rodenticidal knapsack apparatus consists of a reservoir (1) with a cover (2) through an opening in which a ripper shaft (3) with a blade (4) in the lower part, two shoulder straps (5) and an exhaust valve (6) are inserted into the reservoir the bottom of the tank before connecting to the hose (7). A hose detachably connects the reservoir and the connecting tube (8), which has an outlet valve (9) and is rigidly connected at an acute angle to the cylinder (10). A metering piston (11) is placed in the cylinder, rigidly connected to the rod (12), and the rod to the handle (13). In the cylinder there is a side slot (14) for the longitudinal movement of the handle and an opening for the cotter pin (15), which, using the washer (16), fixes the coil spring (17) in the cylinder.

 The knapsack device rodenticidal works as follows.

 The tank (1), loaded with a grain or granular rodenticidal bait, is supported behind the back of the worker using two shoulder straps (5). The outlet valve of the tank (6) in the open position passes the bulk contents of the tank under the action of gravity into the hose (7). The connecting tube (8) when the valve (9) is open ensures that the bait enters the cylinder (10). The metering piston (11), which is located in the cylinder, occupies its upper position under the action of a spring (17), while the piston slot is at the level of the opening of the connecting tube. In this position, the volume of the piston slot is filled with bait under the action of gravity. Moving the handle (13), which is located in the lateral slot (14), to the lower position, respectively, displays the piston in the lower position, in which the piston slot is outside the cylinder and the bait falls out. At this time, the exit from the connecting tube is closed by the solid part of the piston. After that, the handle, released from the pressure of the hands, under the action of the spring returns to its original upper position and the duty cycle can be repeated. Tracking of the bait in the tank is eliminated by turning the ripper rod around its axis. The valves are brought into the closed position in the inoperative state of the device, when it is loaded or disassembled.

 Thus, the task set - increasing labor productivity and improving the safety of rodenticidal treatments - is achieved.

 A device for introducing toxic grain and granular baits into rodent burrows increases labor productivity and increases sanitary and environmental safety.
