Description

Technical Field

[0001] This utility model relates to the field of breeding rack technology, and in particular to a hybrid rice breeding rack. Background Technology

[0002] Hybrid rice breeding is a key technology for improving rice yield and quality. Its core lies in artificial pollination, which involves removing the stamens of the female parent and transferring pollen from the male parent to produce hybrid seeds with heterosis. This process requires extremely high precision and purity in its operation.

[0003] Currently, hybrid rice breeding is mainly carried out in the field or on dedicated breeding racks. Existing breeding racks mainly fall into two categories: one is a simple static rack that provides a fixed operating platform for the rice panicle; the other is a vertical circulating rack equipped with a conveyor chain that automates watering and lighting by moving trays. However, regardless of whether the design is static or dynamic, these breeding racks still require staff to manually operate each rice panicle in front of the rack during the final critical breeding stage.

[0004] When operating in front of the breeding rack, staff must first stabilize the slender and easily swaying rice stalks with one hand, and then use tweezers, scissors and other tools with the other hand to perform delicate steps such as trimming the husks, removing the emasculates and pollinating. This method of fixing with one hand and operating with the other is not only inefficient and easily leads to fatigue in the staff's arms, neck and shoulders, but the swaying of the rice stalks may also damage the flower organs, affect the pollination success rate, and reduce the breeding efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hybrid rice breeding rack.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hybrid rice breeding rack includes two support plates. A conveyor chain is provided on the side of the two support plates that are close to each other. Several trays are rotatably arranged between the two conveyor chains. A fixing structure for fixing hybrid rice is provided between the two support plates. The fixing structure includes two movable plates arranged between the two support plates. Several fixing strips are fixed on the side of the two movable plates that are far from each other. The fixing strips are evenly distributed along the length of the movable plates. Several fixing notches are opened on both sides of the fixing strips.

[0008] As a further embodiment of this utility model, a fixing plate is fixed to one side of the support plate located on the right side. A straight hole is opened on the top surface of the fixing plate. An mounting plate is slidably arranged on the top surface of the fixing plate. Two oblique holes are opened on the top surface of the mounting plate. The oblique holes are connected to the straight hole. A sliding shaft is slidably arranged inside the two oblique holes. The two sliding shafts pass through the straight hole and are fixed to the top surface of the two movable plates respectively. A threaded sleeve is fixed to the top surface of the mounting plate. A screw is threadedly connected inside the threaded sleeve. One end of the screw passes through one side of the corresponding support plate and is fixed with two first synchronous pulleys.

[0009] As a further embodiment of this utility model, two operating plates are rotatably arranged between the two support plates. The right rotating shaft of the operating plate passes through one side of the corresponding support plate and fixes two second synchronous pulleys. The two second synchronous pulleys are respectively engaged with the corresponding first synchronous pulleys by synchronous belts. A first motor is fixed on one side of the right support plate, and the output end of the first motor is fixed to one end of the screw.

[0010] As a further embodiment of this utility model, a limiting strip is fixed on one side of each of the two support plates that are close to each other. The cross-section of the two limiting strips is C-shaped and they are arranged opposite each other. The two sides of the two movable plates are respectively slidably arranged with the interior of the corresponding limiting strip.

[0011] As a further embodiment of this utility model, two guide cylinders are fixed on the top surface of the mounting plate, and a limit rod is slidably provided inside each of the two guide cylinders. One end of the limit rod is fixed to one side of the corresponding support plate.

[0012] As a further embodiment of this utility model, four sprockets are rotatably provided on the side of each of the two support plates that are close to each other, and a connecting rod is fixed between each pair of sprockets. The two conveyor chains are respectively engaged with the four corresponding sprockets. A second motor is fixed on one side of the left support plate, and the output end of the second motor passes through one side of the support plate and is fixed to the corresponding sprocket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This hybrid rice and breeding rack, through its fixed structure, uses a motor-driven screw and oblique hole mechanism to synchronously control the extension and retraction of the two movable plates, ensuring that the fixing notches on the fixing strips reliably hold the rice spike stalks. This effectively avoids damage to the flower organs caused by plant shaking during manual fixing, providing a stable foundation for subsequent precision operations. At the same time, the synchronous pulley and synchronous belt transmit power to the operating plate, automatically rotating it from a vertical storage state to a horizontal working position. This provides a convenient tool placement platform for workers, improving their operating posture. Thus, while freeing up their hands and reducing labor intensity, it enhances the overall efficiency and stability of the series of operations, including pruning, demasting, and pollination.

[0023] Reference Figures 1-4A hybrid rice breeding rack includes two support plates 1. A conveyor chain 2 is provided on the side of the two support plates 1 that is close to each other. A plurality of trays 3 are rotatably arranged between the two conveyor chains 2. A fixing structure for fixing hybrid rice is provided between the two support plates 1. The fixing structure includes two movable plates 201 arranged between the two support plates 1. A plurality of fixing strips 202 are fixed on the side of the two movable plates 201 that is far from each other. The plurality of fixing strips 202 are evenly distributed along the length direction of the movable plates 201. A plurality of fixing notches 203 are opened on both sides of the plurality of fixing strips 202.

[0024] In this embodiment, a fixing plate 204 is fixed to one side of the support plate 1 on the right side. A straight hole 205 is provided on the top surface of the fixing plate 204. A mounting plate 206 is slidably disposed on the top surface of the fixing plate 204. Two oblique holes 207 are provided on the top surface of the mounting plate 206, which communicate with the straight hole 205. A sliding shaft 208 is slidably disposed inside each of the two oblique holes 207. The two sliding shafts 208 pass through the straight hole 205 and are respectively fixed to the top surfaces of the two movable plates 201. A threaded sleeve 209 is fixed to the top surface of the mounting plate 206. A screw 210 is threadedly connected inside the threaded sleeve 209. One end of the conveyor belt passes through one side of the corresponding support plate 1 and is fixed with two first synchronous wheels 211. When the conveyor chain 2 stops to carry out the breeding operation, the screw 210 rotates to make the threaded sleeve 209 move away from the screw 210. The threaded sleeve 209 pushes the mounting plate 206 to move. The movement of the mounting plate 206 makes the two sliding shafts 208 slide in the corresponding inclined holes 207 and move away from each other. Under the limit of the straight hole 205, the two movable plates 201 move away from each other. The two movable plates 201 extend from between the corresponding two support plates 3. The staff can insert the rice stalk to be operated into the fixing notch 203 on one side of the corresponding fixing strip 202.

[0025] In this embodiment, two operating plates 301 are rotatably arranged between the two support plates 1. The right rotating shaft of the operating plate 301 passes through one side of the corresponding support plate 1 and fixes two second synchronous pulleys 302. The two second synchronous pulleys 302 are respectively engaged with the corresponding first synchronous pulleys 211 by synchronous belts 303. A first motor is fixed to one side of the right support plate 1. The output end of the first motor is fixed to one end of the screw 210. When the first motor is started, it drives the screw 210 to rotate, causing the movable plate 201 to extend. While the screw 210 is rotating, it drives the two operating plates 301 to rotate through the transmission of the first synchronous pulley 211, the second synchronous pulleys 302 and the synchronous belt 303, so that the two operating plates 301, which are vertically upward on the left and vertically downward on the right, rotate counterclockwise to the horizontal, thereby facilitating the staff to place tools on the operating plates 301 for breeding operations.

[0026] In this embodiment, limit strips 4 are fixed on the sides of the two support plates 1 that are close to each other. The cross-section of the two limit strips 4 is C-shaped and they are arranged opposite each other. The two sides of the two movable plates 201 are respectively slidably arranged with the interior of the corresponding limit strips 4. The two limit strips 4 limit and guide the movement of the movable plates 201.

[0027] In this embodiment, two guide cylinders 5 are fixed on the top surface of the mounting plate 206. A limit rod 501 is slidably provided inside the two guide cylinders 5. One end of the limit rod 501 is fixed to one side of the corresponding support plate 1. When the mounting plate 206 moves, the limit rod 501 slides inside the guide cylinder 5 to limit and guide the mounting plate 206.

[0028] In this embodiment, four sprockets 6 are rotatably arranged on the side of each of the two support plates 1 that are close to each other. A connecting rod 601 is fixed between each pair of sprockets 6. The two conveyor chains 2 are respectively engaged with the four sprockets 6. A second motor is fixed on one side of the left support plate 1. The output end of the second motor passes through one side of the support plate 1 and is fixed to the corresponding sprocket 6. The second motor drives the sprocket 6 to rotate. Through the connecting rod 601, the two conveyor chains 2 drive the several pallets 3 to move cyclically, so as to realize repeated light and watering of the hybrid rice on the pallets 3.

[0029] Working principle: When the hybrid rice breeding rack starts working, the second motor drives the sprocket 6 to rotate, which drives the conveyor chains 2 on both sides to run synchronously through the connecting rod 601. The conveyor chains 2 then drive the several trays 3 set between them to move slowly in a vertical cycle. This is intended to allow the hybrid rice seedlings placed on the trays 3 to receive light alternately and facilitate even watering.

[0030] When the conveyor chain 2 stops running and the breeding rack enters the breeding operation stage, the core fixing and auxiliary operation mechanism of the device is activated. The first motor fixed on one side of the support plate 1 starts to work, driving the screw 210 to rotate. The threaded sleeve 209, which is threadedly connected to the screw 210, drives the mounting plate 206 to move in a straight line away from the screw 210 under the guidance and constraint of the limit rod 501 and the guide cylinder 5.

[0031] The movement of the mounting plate 206 causes the two inclined holes 207 on its top surface to shift. The upper ends of the two sliding shafts 208 are located in the two inclined holes 207 respectively, and the lower ends pass through the straight holes 205 on the fixed plate 204 and are fixedly connected to the two movable plates 201 respectively. When the inclined holes 207 move, their inclined surfaces will squeeze the sliding shafts 208. Due to the strict limiting effect of the straight holes 205, the sliding shafts 208 cannot move and can only slide laterally along the inclined surface trajectory of the inclined holes 207. This pushes the two movable plates 201 to extend out from between the support plates 1 away from each other under the guidance of the limiting strips 4. Finally, the fixed strips 202 fixed on the movable plates 201 and the fixing notches 203 on their sides reach the working position. The workers can then securely insert the rice stalks to be operated into the appropriate fixing notches 203, thus freeing their hands and eliminating the need to manually fix the rice stalks.

[0032] As the screw 210 rotates, the first synchronous pulley 211 fixed at its end also rotates. The first synchronous pulley 211 transmits power to the second synchronous pulley 302 through the synchronous belt 303. The shaft of the second synchronous pulley 302 directly drives the two operating plates 301 to rotate. This transmission process causes the operating plates 301, which were originally in a vertical position with the left side up and the right side down, to rotate counterclockwise to a horizontal position, providing the staff with a stable tool placement platform, which is convenient for performing delicate operations such as trimming, removing emasculation, and pollination.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
