Detailed Description
The following detailed description of the application refers to the accompanying drawings and preferred embodiments.
FIG. 1 is a top view of the rice low-temperature cold damage breeding test device. The device comprises a fixed box 1 positioned in the center and seedling trays 2 positioned around the fixed phase 1. The fixed box 1 is square in overlooking structure, a cold air fan 11 is arranged in the center of the fixed box 1, fixed air inlets 12 are arranged on four sides of the fixed box 1, and turntables 3 are arranged at four corner positions of the fixed box 1. The top view structure of the seedling tray 2 is square, and the side length of the seedling tray is the same as that of the fixed box 1. The four seedling trays 2 are respectively positioned on the four sides of the fixed box 1 through the turntables 3 at the four corners of the fixed box 1. The four sides of the seedling tray 2 are also provided with seedling tray air openings 21, and the shape of the seedling tray air openings 21 is matched with that of the fixed air openings 12 and can be mutually inserted and fixed.
As shown in fig. 2-3, a structural schematic diagram of the fixed box 1 is shown, four corner positions of the fixed box 1 are provided with turntables 3, the turntables 3 comprise a circular chassis 31, two vertical plates 32 are vertically arranged on the circular chassis 31 in a cross shape, and a turntable rotating shaft 33 is arranged at the center of intersection of the vertical plates 32. The turntable 3 can actively rotate around the center of the turntable rotating shaft 33, and a specific rotation driving mode can be a conventional motor-driven gear rotation structure, and the rotation driving structure is a prior art and is not described herein. In addition, bounding wall 13 has around the fixed case, and bounding wall 13 middle part forms fixed wind gap 12. When the turntable 3 is rotated to a state where the vertical plate 32 thereof is parallel to the coaming 13, the end of the coaming 13 is aligned with the end of the vertical plate 32, and the vertical plate 32 and the coaming 32 at the four corners of the stationary box 1 together form an internal cavity of the stationary box 1. After the cold air fan 11 in the center of the fixing box 1 performs cold air blowing in this state, cold air with low temperature enters the four seedling trays 2 from the four fixing air openings 12 around through the internal cavity.
As shown in fig. 4, the seedling tray 2 has a square structure, and the length of the side of the seedling tray is equal to the distance between two adjacent rotating shafts 33 of the rotating discs on the fixed box 1. When the turntable 3 rotates to a state that the vertical plates 32 of the turntable 3 are parallel to the coaming 13, the seedling tray 2 can be clamped into the clamping space formed by the vertical plates 32 of two adjacent turntable 3, meanwhile, two corners of the seedling tray 2, which are connected with the fixed box 1, are fixedly supported by the round tray bottoms 31 of the two turntable 3, and the seedling tray air port 21 of the seedling tray 2 is inserted into the fixed air port 12 to connect the inner space of the seedling tray 2 with the inner cavity of the fixed box 1. At four angular positions of the seedling tray 2, fixed magnets 22 are provided, which are matched with a circular tray bottom 31 and a vertical plate 32 of the turntable 3. The structure of the turntable 3 and the manner in which the turntable 3 fixes the seedling tray 2 will be described below.
As shown in fig. 5-6, two vertical plates 32 standing on the circular disc bottom 31 in a cross shape divide the turntable 3 into four quadrant regions, each quadrant comprises a quarter part of the circular disc bottom part and two vertical plate parts, a group of independent electromagnets 34 are respectively arranged on each quadrant region, and each group of electromagnets 34 comprises a horizontal part 341 positioned on the circular disc bottom and a vertical part 342 positioned on the vertical plate, and the horizontal part 341 and the vertical part 342 of each group of electromagnets 34 are commonly electrified and powered off. The shape of the fixed magnets 22 at the four corners of the seedling tray 2 is matched with the electromagnet 34 of each quadrant. Thereby positioning and fixing the two corners of one seedling tray 2 by the electromagnets 34 on the two quadrants corresponding to the adjacent two turntables 3.
In order to enable the four directions of the seedling tray 2 to be blown by low-temperature cold air, the seedling tray 2 can be indexed by a turntable. As shown in fig. 7, in the indexing state, the electromagnet 34 in one quadrant of one turntable 3 is positioned and fixed at one corner of one seedling tray 2, and the four turntable 3 synchronously rotate in the same direction, so that the seedling tray 2 shown in fig. 1 can be indexed to an adjacent side, and the seedling tray air port 21 on the other side of the seedling tray 2 is inserted into the fixed air port 12 on the other side, and for a single seedling tray 2, the direction of low-temperature cold air blowing is changed by 90 degrees, and after four indexing, the four directions of the single seedling tray 2 are subjected to cold air simulation, so that the environment simulation of low-temperature cold air can be uniformly received by rice test plants in each seedling tray, and the stability of a low-temperature breeding test is improved.
The following describes a control method of the electromagnet 34 of the turntable 3 when the seedling tray 2 is indexed. When the seedling tray 2 is in butt joint with the fixed box 1 for ventilation simulation, the seedling tray 2 is called a fixed state, and the transposition process of the seedling tray 2 is called a transposition state. The manner of controlling the turntable 3 during indexing of the seedling tray 2 will be described below taking one complete cycle from the fixed state-the indexing state-the fixed state as an example.
As can be seen from the foregoing, in the fixed state, adjacent turntables 3 fix the same seedling tray by electromagnets 34 on two opposite quadrants. For the fixed case 1, taking one of four sides as an example, two electromagnets 34 at two ends are included, and the electromagnet 34 on one turntable 3 is used as a main fixing position a, and the electromagnet 34 on the other turntable 3 on the same side is used as a secondary fixing position B. Thus, the stationary box 1 has one main stationary position a and one auxiliary stationary position B on each side. Providing each turntable 3 with only one primary fixing position a and one secondary fixing position B at the same time, a schematic diagram of the primary and secondary fixing positions of the turntable 3 is formed as shown in fig. 8. For the stationary box 1, each side has a primary fixing position a and a secondary fixing position B, for the turntable 3, each turntable has both a primary fixing position a and a secondary fixing position B, and the quadrants of the primary fixing position a and the secondary fixing position B on the turntable 3 are not adjacent.
The indexing method from the fixed state-the indexing state-the fixed state is described below with reference to fig. 9:
s1: in the fixed state of the seedling tray 2, the electromagnet 34 of each main fixed position A and the electromagnet 34 of the auxiliary fixed position B are electrified, so that two corners of the seedling tray 2 are fixed by the electromagnets 34 of the main fixed position A and the auxiliary fixed position B;
s2: the electromagnet 34 of the auxiliary fixing position B on each side of the fixing box 1 is powered off, and one corner of the seedling tray 2 is separated from the fixing of the auxiliary fixing position B;
s3: the four turntables 3 synchronously rotate in the same direction, and stop rotating after rotating 180 degrees; at this time, the seedling tray 2 is indexed to the adjacent other side of the fixed box 1 for butt joint by the rotation of the turntable 3. During rotation, the electromagnet 34 of the main fixing position A of each turntable 3 is still electrified to keep fixing one corner of the seedling tray 2 in a fixed state before rotation, so that the seedling tray 2 can be synchronously indexed to the other side position.
S4: the electromagnet 34 of the main fixing position A and the electromagnet 34 of the auxiliary fixing position B are redefined, and simultaneously the electromagnet 34 of the main fixing position A and the electromagnet 34 of the auxiliary fixing position B are electrified to enter a fixing state again, so that seedling tray transposition is completed. It should be pointed out at this step that, due to the rotation of the rotating disc 3, the electromagnet 34 of the primary fixed position a in the previous fixed state enters the position of the secondary fixed position B on the other side after rotating 180 °, and at this time, the primary fixed position a and the secondary fixed position B of the electromagnet 34 on each rotating disc 3 need to be redefined to ensure the normal operation of the next rotation cycle.
The foregoing is merely a preferred embodiment of the present application and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present application, which are intended to be comprehended within the scope of the present application.
