Description

A recoil type fertilizing seeder

technical field

The utility model relates to an agricultural fertilizing machine, in particular to a recoil type fertilizing seeder.

Background technique

The patent document with the publication number CN204669880U discloses a high-efficiency knapsack electric fertilizer spreader, including a fertilizer spreader body, a variable speed motor is installed on the inner bottom of the fertilizer spreader body, and the variable speed motor is connected to the rotating body by transmission, and the interior of the fertilizer spreader body is also installed There is a variable speed circuit, a control knob is installed on the right side of the surface of the fertilizer applicator body, an adjustment plate is connected to the bottom of the feed bin through a hinge, and an adjustment block is connected to the left end of the adjustment plate. The high-efficiency knapsack electric fertilizer spreader is equipped with an adjustment plate and an adjustment block to adjust the amount of fertilizer output, and can also adjust the speed of the variable-speed motor according to actual needs to make the fertilization range more accurate. The rotating body is used to replace the original blades. , The fertilizer is thrown out by centrifugal force, which achieves the effect of uniform discharge, does not cause waste, and improves the efficiency of fertilization. However, this technical solution has the disadvantage that fertilizer spreading is poorly oriented and directional spreading cannot be realized.

Contents of the invention

The utility model aims to provide a recoil type fertilizing seeder, which can realize directional sowing of fertilizers and seeds, expand the sowing range, improve fertilization efficiency, and enhance the applicability of the fertilizing seeder.

The technical solution adopted by the utility model is: a recoil type fertilizing seeder, including a storage tank with a recoil pipe installed at the conical bottom, one end of the recoil pipe communicates with the air outlet pipe of the air blower, and the other end passes through a soft The pipe is connected to the hand-held nozzle; several feeding troughs are arranged on the side wall of the vertical section of the recoil pipe.

When working, the air blower works to generate airflow to blow to the air outlet pipe, and the airflow flows from the air outlet pipe to the recoil pipe, blowing upward the fertilizer, seeds and other materials that enter the recoil pipe through the feeding trough, and pass through the other side of the recoil pipe. The port is fed into the hose, and then sprayed and thrown out of the machine through the hand-held nozzle to achieve directional spreading. Under the action of gravity and airflow, the material in the storage tank will continuously enter the recoil pipe from the feeding trough, and be carried by the airflow and thrown out from the hand-held nozzle.

A conical material cover fixed on the wall of the material storage tank is arranged above the feeding trough, and a plurality of feeding holes are arranged on the material cover. The material cover can disperse the pressure of material accumulation at the material chute to prevent the material from clogging here; the material above the material cover will fall into the material cover through the material drop hole on the material cover to ensure that the material passes through the material chute continuously Fall into the recoil tube.

A non-return one-way ventilation valve is arranged in the air outlet pipe or the recoil pipe. The non-return one-way ventilation valve can ensure that the airflow generated by the air blower blows to the recoil pipe through the air outlet pipe, and can prevent excessive material from falling into the recoil pipe from the feeding chute, blocking the pipe for a long distance or even flowing into the air blower , affecting the work of the air blower.

An air volume regulator is installed on the above-mentioned air blower. The air volume of the air blower is changed by the air volume regulator, and the airflow velocity in the air outlet pipe is adjusted, so that the fertilization and seeding speed and range can be changed.

The utility model generates airflow through the air blower, blows the materials entering the recoil pipe from bottom to top, and sprays and throws the materials out of the machine. It has the advantages of smooth material discharge and not easy to block the material in the machine; the hand-held nozzle with hose can realize the directional sowing operation at any angle, which solves the technical problem of fertilization seeder adapting to the edge of the field.

detailed description

Below, the specific embodiment of the present utility model will be further described in conjunction with the accompanying drawings.

Fig. 1 shows the embodiment of a kind of recoil type fertilizing seeder, comprises the storage tank 1 that conical bottom is installed with recoil pipe 2, and recoil pipe 2 one ends are communicated with the outlet pipe 31 of blower 3, The other end is connected to the hand-held nozzle 4 through a hose 41; several feeding troughs 21 are arranged on the side wall of the vertical section of the recoil pipe 2. The operator adjusts the hand-held nozzle 4 to change the spraying direction of fertilizers and seeds, so as to realize directional sowing.

Fig. 2 shows the embodiment of another kind of recoil type fertilizing seeder, comprises the storage tank 1 that recoil pipe 2 is installed at the conical bottom, and one end of recoil pipe 2 communicates with the outlet pipe 31 of blower 3 , the other end communicates with the hand-held nozzle 4 through a flexible pipe 41; several feeding troughs 21 are arranged on the side wall of the vertical section of the recoil pipe 2, and a conical material cover 5 fixed on the wall of the storage tank 1 is arranged above the feeding trough 21, A plurality of blanking holes are arranged on the material cover 5, and a non-return one-way ventilation valve 32 is arranged on the inner wall of the air outlet pipe 31. When the air blower 3 is not working, the valve of the non-return one-way ventilation valve 32 is closed, which can prevent materials such as fertilizers and seeds from After falling into the recoil pipe 2 from the feeding trough 21, it flows into the air blower 3. When the air blower 3 is working, the check valve 32 is opened, and the airflow generated by the air blower 3 flows through the air outlet pipe 31. The recoil pipe 2 carries the material and sprays it out of the machine through the hose 41 and the hand-held nozzle 4. Fig. 3 shows that several feeding troughs 21 are arranged on the side wall of the vertical section of the recoil pipe 2 in the embodiment. FIG. 4 shows that a plurality of drop holes 51 are arranged on the material cover 5 in the embodiment, so that the materials above the material cover 5 can drop down to the bottom of the material cover 5 .
