Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural biological control and drone technology application, and particularly relates to a screw conveyor and throwing device for trichogramma storage eggs balls. Background Art

[0002] As a natural enemy insect, trichogramma can parasitize the eggs of lepidopteran pests such as corn borers, cotton bollworms, and rice leaf rollers, and eliminate the pest larvae by laying eggs in the host eggs, thus achieving biological control. The storage egg ball is usually a round ball with a diameter of about two centimeters. Tussah eggs or other carriers parasitized by trichogramma are placed in the middle part. After being put into the field, trichogramma can emerge from it and search for pest eggs to parasitize. At present, the drone farmland aerial fixed-point and quantitative throwing device for trichogramma storage egg balls is an innovative agricultural device that combines biological control and drone technology.

[0003] There are two types of existing throwers. One type is to use a spiral ramp track arranged on the barrel wall of a barrel-shaped container to arrange the storage egg balls on the track, and use the gravity of the balls and an automatically controlled gate to release the storage egg balls. The disadvantage of this device is that the space utilization rate in the container is too low, the shape is large, and as a load of the drone, its wind resistance is too large, the structure inside the container is complex, and the weight is large, which is not suitable for being thrown by a drone.

[0004] The other type of thrower is to make the container into a cylindrical upper part and a conical lower part. A control gate is set at the small end of the inverted cone to quantitatively release the storage egg balls. The disadvantage of this type of thrower is that the balls often form a stable support structure by squeezing each other in the circular container under the action of gravity in the container, resulting in a ball-free area in the uncertain area above the gate, causing ball-free throwing after the gate is opened. Therefore, a stirring motor and a long rod stirrer are added to the upper cover of the container to stir the storage egg balls in the cylinder to make them move to the gate opening, but the phenomenon of ball blocking still occurs. A vibrator is added to break the stable state of extrusion between the balls by vibration, and the balls enter the channel smoothly by gravity to reach the gate opening. The electric control gate is a horizontal rotating partition door that can only accommodate 1 ball, and one ball is thrown every time it rotates an angle. Summary of the Invention

[0005] The purpose of the present invention is to provide a screw conveyor and throwing device for trichogramma storage egg balls to solve the problems that the current trichogramma storage egg ball throwing device has a complex structure, is not suitable for being thrown by a drone, or the balls move to the throwing port gate in the cylinder by their own gravity, and are easily stuck by uncertain factors, resulting in throwing failure.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A screw conveyor and throwing device for trichogramma storage egg balls, comprising:

[0007] A housing is provided with a coupling. Inside the housing, a screw conveyor and a ball storage tank are provided. The motor shaft of a stepping motor is connected to the screw conveyor through the coupling. The balls are located in the ball storage tank. The top of the ball storage tank is provided with a feed inlet.

[0008] And an electric spring type stirrer is installed on the housing and is used to stir the balls so that the balls fall onto the screw conveyor. A throwing port is provided on the housing, and a counting and signaling microswitch is provided on the inner wall of the throwing port.

[0009] As a further description of the above technical solution:

[0010] The housing is provided with a buckle, and the electric spring type stirrer is installed on the slope of the housing through the buckle.

[0011] As a further description of the above technical solution:

[0012] The electric spring type stirrer includes a motor, a rotating plate and a plurality of springs. The motor is installed on the buckle, the rotating plate is connected to the motor shaft of the motor, and the plurality of springs are connected to the rotating plate.

[0013] As a further description of the above technical solution:

[0014] The lengths of the plurality of springs are different.

[0015] As a further description of the above technical solution:

[0016] The screw conveyor includes a screw and a spiral blade. The motor shaft of the stepping motor is connected to the screw through the coupling, and the spiral blade is sleeved on the screw.

[0017] As a further description of the above technical solution:

[0018] The screw and the spiral blade enclose a continuous spiral channel, and a plurality of spiral grooves are provided on the continuous spiral channel.

[0019] As a further description of the above technical solution:

[0020] The width of the spiral groove is 1.05 - 1.1 times the diameter of the ball.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In the present invention, a ball storage groove and a screw conveyor are arranged inside the housing. An electric spring-type stirrer is installed on the slope of the housing. There are three springs with different lengths on the spring-type stirrer, so that when it rotates at a low speed, it stirs the Trichogramma egg storage spheres at different positions. When the spheres fall into the spiral groove in the screw conveyor, the Trichogramma egg storage spheres are in a ready-to-throw state. When the UAV reaches the coordinate of the throwing plot and issues a throwing command, the stepping motor rotates one circle, the Trichogramma egg storage spheres are pushed out of the throwing port, the counting and signaling microswitch is turned on, a throw is made, and the throwing success signal is transmitted back to the control platform. This structure is simpler than the prior art and does not require devices to be set on the cylinder to assist the movement of the spheres in the ball storage cylinder. The movement of the spheres in the screw conveyor is electrically propelled, and the reliability of throwing can reach 100%, and no missed throws will occur.

[0023] 2. In the present invention, the ball storage groove for storing the spheres adopts a cylindrical plus inverted conical barrel structure, which is convenient for the spheres to move towards the screw conveyor at the bottom. The electric control gate is cancelled, and a stepping motor is set to drive the screw conveyor to convey the spheres. The upper part of the screw conveyor is connected to the ball storage groove, enabling multiple spheres to fall into the spiral groove simultaneously. An electric spring-type stirrer is arranged on the slope on one side of the screw conveyor (the slope on the housing). The motor drives the rotating plate to rotate, thereby driving the spring to rotate, so that the spring stirs the spheres in the ball storage groove, causing the spheres squeezed in the ball storage groove to move and fall into the spiral groove. The stepping motor drives the screw to rotate, and one ball position is advanced towards the throwing port for each rotation. When the screw conveyor rotates, it will also push other spheres in the ball storage groove, assisting the movement of the spheres and ensuring the normal throwing of the thrower.

[0035] Please refer to Figure 1-2 , the present invention provides a technical solution: a trichogramma egg storage ball screw conveyor and throwing device, comprising:

[0036] A housing 1, on which a coupling 8 is provided. Inside the housing 1, a screw conveyor 6 and a ball storage tank are provided. The motor shaft of a stepping motor 3 is connected to the screw conveyor 6 through the coupling 8. A sphere 5 is located in the ball storage tank. The top of the ball storage tank is provided with a feed port 9.

[0037] And an electric spring type stirrer 2, which is installed on the housing 1 and is used to stir the sphere 5 so that the sphere 5 falls onto the screw conveyor 6. A throwing port 10 is provided on the housing 1, and a counting and signal-sending micro switch 7 is provided on the inner wall of the throwing port 10.

[0038] A buckle 4 is provided on the housing 1, and the electric spring type stirrer 2 is installed on the slope of the housing 1 through the buckle 4, so that the electric spring type stirrer is inclined. In this position, the sphere at the top of the spiral groove can be stirred so that the sphere can smoothly fall into the spiral groove.

[0039] The electric spring type stirrer 2 includes a motor 21, a rotating plate 22 and a plurality of springs 23. The motor 21 is installed on the buckle 4, the rotating plate 22 is connected to the motor shaft of the motor 21, and a plurality of the springs 23 are connected to the rotating plate 22.

[0040] The lengths of the plurality of springs 23 are different. The electric spring type stirrer is equipped with 3 springs with different lengths, so as to stir the trichogramma egg storage spheres at different positions during low-speed rotation. When the sphere falls into the spiral groove in the screw conveyor, the trichogramma egg storage sphere is in a state of being ready to be thrown.

[0041] The screw conveyor 6 includes a screw 61 and a spiral blade 62. The motor shaft of the stepping motor 3 is connected to the screw 61 through the coupling 8, and the spiral blade 62 is sleeved on the screw 61.

[0043] The width of the spiral groove is 1.05 - 1.1 times the diameter of the sphere 5. To ensure the smooth movement of the sphere in the spiral groove and avoid jamming or interference between adjacent spheres, the clearance margin design of the spiral groove can ensure that slight deformations caused by vibration or temperature changes can be absorbed by the clearance margin, avoiding mechanical interference.

There are 3 springs with different lengths on the spring-type stirrer, so that it stirs the Trichogramma egg storage spheres at different positions when rotating at a low speed. When the spheres fall into the spiral grooves in the screw conveyor, the Trichogramma egg storage spheres are in a ready-to-throw state. When the drone reaches the coordinates of the throwing plot and issues a throwing instruction, the stepping motor rotates one circle, the Trichogramma egg storage spheres are pushed out of the throwing port, the counting and signaling microswitch is turned on, and a throw is made, and the throwing success signal is sent back to the control platform. This structure is simpler than the prior art and does not require devices to be set on the cylinder to assist the movement of the spheres in the ball storage cylinder. The movement of the spheres in the screw conveyor is electrically propelled, and the throwing reliability can reach 100%, without causing missed throws.
