Detailed ways

As shown in Figures 1 to 14, the present invention mainly includes a box 1, a partition frame 6, a partition 2, a spawning plate 4 and a swing mechanism. The present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , the box body 1 is a rectangular parallelepiped structure, and the bottom of the box body is provided with legs 11 for easy support. The whole box is surrounded by six transparent glass plates, front, rear, left, right, upper and lower. A shading cloth 12 is wrapped on the outside of the left half of the box body. The setting of the shading cloth makes the inside of the left end of the box body darker than the right end, thereby creating a dark environment, and the left end of the box body is a camera obscura.

There are several partitions 2 arranged up and down in the box. As shown in Figure 2, Figure 3, Figure 4 and Figure 9, the partition 2 is a U-shaped structure, and long grooves are respectively provided on the front and rear side walls of the partition. 21. The first end of the long groove is provided with a first limiting groove 22 placed in the partition plate. As shown in Figure 5, the second end of the long groove is provided with a second limiting groove placed in the partition plate. 23. Both the first and second limiting grooves communicate with the long groove. The baffle is movably arranged on the baffle frame 6, the baffle frame is essentially a rectangular plate, and the baffle frame is placed in the box. A pair of front and rear support rods 5 are arranged on the partition frame. As shown in Figure 10, the support rod is a straight rod, a groove 51 is provided in the upper part of the support rod, and a tooth is provided on the lower part of the support rod. A number of connecting pieces 3 are arranged between the partitions. As shown in Figure 8, the connecting pieces 3 are strip-shaped structures, the first end of the connecting piece is provided with a circular hole, and the first end of the connecting piece is hinged with the support rod after installing the hinge shaft connected together, and the first end of the connector is placed in the groove. A chute 32 is provided in the second end of the connecting piece, a short shaft 31 is slidably installed in the chute, the first end of the short shaft is circular, and a limit rod 34 is fixed on the first end of the short shaft to limit the The rods are arranged radially along the minor axis. The second end of the stub shaft is a square slider 311, the slider is slidably installed in the chute, and a spring 33 is arranged between the second end of the stub shaft and the inner wall of the chute, under the action of the spring the stub shaft and the connecting piece connected. The first end of the short axis is placed in the long groove, and the partition plate can move relative to the short axis, and can also rotate at a certain angle relative to the short axis. As shown in Figures 6 and 7, a spawning plate 4 is provided on the inner side of the partition, and correspondingly, a slot for accommodating the spawning plate is provided on the inner side wall of the partition, and the spawning plate is inserted into the slot. As shown in FIG. 2 , when the first end of the short axis is in contact with the second end of the long groove, the baffle plate is inclined under the action of its own gravity, and the first end of the baffle plate is low and the second end is high. As shown in FIG. 12 , when the first end of the short axis is in contact with the first end of the long groove, the baffle is inclined under the action of its own gravity, and the first end of the baffle is high and the second end is low. During operation, the relative position between the baffle and the short axis can be changed by pushing and pulling the baffle, and then the inclined direction of the baffle can be changed. The bees are evenly distributed on the spawning board. Under the supporting action of the support rod and the connecting piece, the baffle can only swing left and right in the vertical plane. As shown in FIG. 5 , after the limit rod is in contact with one side of the second limit groove 23, the inclination angle of the baffle is fixed, and the baffle is fixed relative to the support rod at this time; similarly, when the limit rod and the first limit groove After the contact of one side of the partition, the inclination angle of the partition is also fixed, and the partition is fixed relative to the support rod again at this time.

In order to make the clapboard swing back and forth in the vertical plane, a swing mechanism is provided between the support rod and the clapboard frame. As shown in Figures 11 and 12, the swing mechanism includes a shell 75 fixed on the clapboard frame, a The motor 7 on the partition frame, a pair of coaxially arranged driving sprockets 71 rotatably installed in the housing, driven sprockets 72 rotatably installed at both ends of the housing, and the driving sprockets and the corresponding driven chains The chain between the wheels, the first gear 73 arranged coaxially with the driven sprocket at the left end, and the second gear 74 arranged coaxially with the driven sprocket at the right end, wherein the first gear meshes with the support rod on the front side, and the second gear The gear meshes with the support rod on the rear side, and can drive the support rod to move up and down under the action of the first and second gears. The support rod and the partition frame are slidably connected up and down, and the motor directly drives the two driving sprockets to rotate. The casing is provided with a notch 76 for avoiding the first and second gears, so that the first and second gears can protrude from the casing. Since the rotation directions of the driving sprocket and the driven sprocket are the same, the rotation directions of the first and second gears are the same. When the first gear rotates counterclockwise, the support rod meshed with the first gear moves downward; at this time, the second gear rotates counterclockwise, and the support rod meshes with the second gear moves upward. When the first gear rotates clockwise, the support rod meshed with the first gear moves upward; at this time, the second gear rotates counterclockwise, and the support rod meshes with the second gear moves downward. In this way, when the motor works, it can drive the two support rods to move in opposite directions, and because the connecting piece is hingedly connected with the support rod, it can drive the partition plate to swing back and forth. When the partition swings back and forth, the distance between the front side of the partition and the corresponding support rod increases, and the distance between the rear side of the partition and the corresponding support rod increases, and the setting of the spring between the short shaft and the connecting piece can adapt to the partition The need to change the distance between the plate and the support rod.

The method of use of the present invention is described below:

(1) Spread the intermediate host eggs on the spawning plate, and then place the Trichogramma on the spawning plate;

(2) Adjust the position of the clapboard so that the clapboard is inclined to one side and ensure that the inclination direction of each clapboard is consistent, so that the Trichogramma lays eggs;

(3) After a period of time, push or pull the clapboard to make the clapboard tilt to the other side, and continue to let the Trichogramma lay eggs; because the Trichogramma has the habit of moving upwards, after constantly adjusting the inclination direction of the clapboard, it can be So that the Trichogramma is covered with spawning plates along the left and right directions;

(4) According to the need, drive the motor to move, and then move the support rod up and down, so that the baffle plate swings back and forth, and finally makes the baffle plate inclined forward and backward, so that the trichogramma is evenly distributed in the front and rear directions.

In the specific operation, the front end of the partition can be made high and the rear end low when the partition is tilted back and forth. After a certain period of time (such as 2 hours), the left end of the partition can be made high and the right end of the partition can be low; High, the front end is low, and the back end is high, how to adjust the position of the partition, so that the Trichogramma is evenly distributed on the spawning plate. When the Trichogramma is on the spawning plate on one of the partition racks for a period of time (such as 12 hours), the intermediate host eggs on the spawning plate can no longer meet the egg-laying needs of Trichogramma, and the separation should be Trichogramma from spawning plates on plate racks are transferred to new clapboard racks. As shown in FIG. 14 , the partitions on the partition frame can be tilted first, so that the Trichogramma 8 is transferred to the right end of the partition, and then the partitions on the partition frame are inclined in the opposite direction, that is, the partitions are The Trichogramma on the top is placed at the lowest end. Then, place a new clapboard rack on the right side of this clapboard rack, then make the left end of the clapboard on the new clapboard rack low and the right end high, and paint the fresh middle on the spawning plate on the new clapboard rack host egg. Light is applied above the new clapboard frame. At this time, the clapboard frame parasitized by Trichogramma is placed at the left end of the box, and the new clapboard frame is placed at the right end of the box, so that the egg-laying plate on the new clapboard frame Placed in an environment with strong light, the Trichogramma on the egg-laying plate of the left clapboard frame (the clapboard frame after cultivating the Trichogramma) will follow the egg-laying plate of the right clapboard frame from low to high Move around until all is transferred to the spawning plate of the new shelf on the right. In this way, by creating a lighting environment and inclined partitions, Trichogramma's phototaxis and tendency to move upward are utilized to drive the uniform distribution and transfer of Trichogramma. The whole device is easy to operate, and can ensure the uniform distribution of Trichogramma when cultivating Trichogramma, thereby ensuring the egg laying rate of Trichogramma and the utilization rate of intermediate host eggs.
