Abstract

The present invention relates to the technical field of breeding racks, and proposes a breeding rack for rice planting, comprising: a transmission frame, an operating mechanism and a driving mechanism. When the driving mechanism drives the operating mechanism, a plurality of rice planting trays can be cyclically driven in a horizontal state. A plurality of rice planting trays are distributed on each operating mechanism, which can greatly improve the breeding yield in a limited space and fully utilize the space in the effective area. Moreover, each rice planting tray is staggered up and down or left and right, which can effectively reduce the problem of sunlight blocking. In addition, when the rice planting tray is transmitted to a low place, it is convenient to fill and clean the soil inside it, and it is convenient to perform operations such as transplanting, harvesting and observation, and it has a high use value. Two liquid applying mechanisms are symmetrically arranged in the liquid storage tank. In the process of adjusting the position of the rice planting tray, the solution stored in the liquid storage tank can be extracted through the liquid applying mechanism and sprayed into the rice planting tray.

Description

[0002] Rice is one of the main food crops in the world. Billions of people worldwide get their food directly from rice. The production and supply of rice is also one of the important factors affecting the global economy and environment. Therefore, rice planting and breeding are very important. However, the existing breeding racks only have the function of breeding, and the height of the breeding racks cannot be adjusted. When it is necessary to operate the seedlings at high levels, ladders are often required to climb to a high place, which is inconvenient for staff to use.

[0003] After searching, the existing patent (Announcement No.: CN213127254U) discloses a rice planting breeding rack. The rice planting breeding rack is provided with a bottom plate, a first breeding plate, a hinged rod 1, a second breeding plate, a hinged rod 2 and a moving rod. When the motor rotates, the rotating rod is driven to rotate, thereby driving the nylon cloth to rotate to pull the fixed rod to move, thereby driving the moving rod to move. When the rotating rod rotates forward, the nylon cloth can be tightened, thereby raising the second breeding plate. When the rotating rod rotates reversely, the nylon cloth can be loosened, thereby lowering the second breeding plate, thereby achieving the purpose of lifting and lowering the second breeding plate.

Example

[0058] See also Figure 1 , Figure 8 , Fig. 9 , Fig.10 as well as Fig.11 Two liquid applying mechanisms 3 are symmetrically arranged in the liquid storage tank 2. During the position adjustment of the rice planting tray 4, the solution stored in the liquid storage tank 2 can be extracted through the liquid applying mechanism 3 and sprayed into the rice planting tray 4.

[0059] Specifically, the liquid applying mechanism 3 includes a liquid storage frame 32 arranged above the liquid storage tank 2, a cylindrical cavity 38 is opened on the inner side of the liquid storage frame 32, and two slideways 35 are symmetrically opened on the outer wall of the liquid storage frame 32. One end of the liquid storage frame 32 is fixedly connected to a liquid drawing tube 31, and the liquid drawing tube 31 extends to the inside of the liquid storage tank 2. The upper end of the liquid storage frame 32 is fixedly connected to a liquid discharge tube 33, and a flower umbrella 34 is arranged at the other end of the liquid discharge tube 33. One-way valves are arranged at the ends of the liquid drawing tube 31 and the ends of the liquid discharge tube 33 near the side of the cylindrical cavity 38.

[0060] Furthermore, the liquid application mechanism 3 also includes a linkage component 36, which includes two rocker arms 363 symmetrically and rotatably arranged on the outer wall of the liquid storage frame 32, a push-pull column 366 is provided on the inner sliding sleeve of the cylindrical cavity 38, and two fixed shafts 365 are symmetrically fixed to the outer wall of the push-pull column 366, the fixed shaft 365 is slidably sleeved inside the slide 35, and a second connecting rod 364 is hinged between the fixed shaft 365 and the rocker arm 363, a U-shaped frame 362 is hinged between the two rocker arms 363, a first connecting rod 361 is hinged at the bottom of the U-shaped frame 362, a rocker frame 367 is fixedly connected between the two rocker arms 363, and two threaded pressure rods 368 are threadedly connected to the end of the rocker frame 367 away from the liquid storage frame 32.

[0061] Furthermore, the liquid application mechanism 3 also includes a reset component 37, which includes a fixed barrel 373 fixedly connected to the top of the liquid storage tank 2, and a movable plug 371 is provided on the inner sliding sleeve of the fixed barrel 373. The upper end of the movable plug 371 is hinged to the first connecting rod 361, and a reset spring 372 is connected between the movable plug 371 and the bottom of the fixed barrel 373.

[0062] In the present embodiment, when it is necessary to add water or supplement nutrient solution to the inside of the rice planting tray 4, an appropriate amount of water or supplement nutrient solution is injected into the liquid storage tank 2 in advance. When the rice planting tray 4 is driven by the operating mechanism 6, the bottom of the rice planting tray 4 can press the threaded pressure rod 368, so that the threaded pressure rod 368 drives the swing rod 363 to rotate on the outer wall of the liquid storage frame 32 through the swing frame 367, and the swing rod 363 pulls the fixed shaft 365 through the second connecting rod 364, and the swing rod 363 is driven by the second connecting rod 364. 63 lifts the movable plug 371 through the U-shaped frame 362, so that the reset spring 372 is stretched, and the push-pull column 366 moves to the right inside the columnar cavity 38, so that the water or nutrient solution inside the columnar cavity 38 can be pushed. During this process, the one-way valve at the end of the suction tube 31 is closed, and the one-way valve at the end of the discharge tube 33 is opened, so that the water inside the columnar cavity 38 can be transported to the flower umbrella 34 through the discharge tube 33, and sprayed toward the inside of the rice planting tray 4 through the flower umbrella 34.

[0063] Working principle and usage process: When working, turn on the power and start the motor 82. The motor 82 drives one of the pulleys 81 to rotate through the output shaft, thereby driving the other pulley 81 to rotate through the transmission belt 83, and then driving the two first sprockets 62 located on the lower side to rotate, thereby driving the high-position chain 61 to transmit. The high-position chain 61 drives the first star frame 641 to transmit. The first star frame 641 drives the second star frame 646 to transmit through the first connecting plate 642, the guide rod 644, the second connecting plate 643 and the support rod 645. The second star frame 646 drives the low-position chain 65 to transmit. During this process, the guide rod 644 slides along the inner side of the track 53, and the first connecting plate 642 and the second connecting plate 643 remain in a vertical state, so that the rice planting tray 4 can be in a horizontal state during the transmission process.

[0064] When the rice planting tray 4 is driven to a lower position, it is convenient to fill and clean the soil inside it, and to carry out operations such as transplanting and harvesting. When it is necessary to add water or supplement nutrient solution to the rice planting tray 4, an appropriate amount of water or supplement nutrient solution is injected into the liquid storage tank 2 in advance. When the rice planting tray 4 is driven by the operating mechanism 6, the bottom of the rice planting tray 4 can press the threaded pressure rod 368, so that the threaded pressure rod 368 drives the swing rod 363 to rotate on the outer wall of the liquid storage frame 32 through the swing frame 367, and the swing rod 363 pulls the fixed shaft 365 through the second connecting rod 364, and the swing rod 363 is driven by the second connecting rod 364. The movable plug 371 is lifted up through the U-shaped frame 362, so that the reset spring 372 is stretched, and the push-pull column 366 moves to the right inside the columnar cavity 38, so that the water or nutrient solution inside the columnar cavity 38 can be pushed. In this process, the one-way valve at the end of the suction pipe 31 is closed, and the one-way valve at the end of the discharge pipe 33 is opened, so that the water inside the columnar cavity 38 can be transported to the flower umbrella 34 through the discharge pipe 33, and sprayed toward the inside of the rice planting tray 4 through the flower umbrella 34.

[0065] When the rice planting tray 4 moves down to a certain extent, that is, when the threaded pressure rod 368 drives the swing frame 367 to rotate to a certain extent, the rice planting tray 4 will be separated from the threaded pressure rod 368. At this time, under the action of the reset spring 372, the movable plug 371 moves down and resets, and the U-shaped frame 362 is pulled down by the first connecting rod 361, so that the swing rod 363 drives the swing frame 367 to flip and reset, and the fixed shaft 365 is pushed by the second connecting rod 364, so that the push-pull column 366 moves left and resets, so that the pressure of the space on the right side of the column cavity 38 is reduced, so that the one-way valve at the end of the liquid drawing tube 31 is opened, and the one-way valve at the end of the liquid discharge tube 33 is closed, and the solution inside the liquid storage tank 2 is drawn into the column cavity 38 for temporary storage through the liquid drawing tube 31, providing a water source for the water adding work on the next side.

[0066] By rotating the threaded pressure rod 368 inside the swing frame 367, the extension length of the threaded pressure rod 368 can be adjusted. When it is not necessary to add water or replenish nutrient solution, the threaded pressure rod 368 is twisted in the direction close to the liquid storage frame 32 until the bottom end of the rice planting tray 4 does not come into contact with the threaded pressure rod 368 during the transmission process. When it is necessary to add water or replenish nutrient solution, the threaded pressure rod 368 is twisted in the direction away from the liquid storage frame 32. According to the amount of water required, the leftward movement distance of the threaded pressure rod 368 is adjusted. The greater the leftward movement distance, the greater the downward pressure angle of the rice planting tray 4 on the threaded pressure rod 368, so that more water is squeezed out from the inner side of the columnar cavity 38. Conversely, the smaller the leftward movement distance, the smaller the downward pressure angle of the rice planting tray 4 on the threaded pressure rod 368, and the shorter the distance the push-pull column 366 moves, so that less water is squeezed out from the inner side of the columnar cavity 38. For details, refer to Fig.10 and Fig.11 .

[0067] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
