Description

Technical Field

[0001] This utility model relates to the technical field of non-destructive separation of rice buds, and in particular to a non-destructive separation device for rice buds. Background Technology

[0002] Rice is an important food crop in my country and globally, and the level of mechanized cultivation directly affects grain yield and agricultural production efficiency. During mechanized seedling raising and sowing, seeds typically need to be screened and separated to remove unripe and small seeds.

[0003] Currently, among existing separation equipment, such as the patent with authorization announcement number CN221638717U, this utility model provides a seed separation device, which relates to the field of separation device technology. It includes a separation mechanism, a straw cleaning mechanism is fixedly installed on one side of the outer wall of the separation mechanism, the separation mechanism includes a bracket, four first support blocks are fixedly installed on the top of the bracket, and a first fixing block is fixedly installed on the inner surface of each of the four first support blocks. A first slot is opened on the top of each of the four first fixing blocks.

[0004] However, it was found during the use of the device that it was not convenient to separate and store seeds of different sizes separately, which reduced the ease of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a non-destructive separation device for rice seedlings that improves the effect of separating and storing seedlings of different sizes, facilitates the separation of shell fragments mixed in the seedlings, reduces the damage rate of seedlings, and improves the non-destructive separation effect.

[0006] This utility model discloses a non-destructive rice seed germ separation device, comprising a support frame and a hopper, the hopper being installed on the outer wall of the support frame; it also includes a discharge device, a support device, a discharge box, a trough, and multiple sets of screen plates. The discharge box is connected to the bottom of the hopper, and the discharge device is installed inside the discharge box to discharge a quantitative amount of seeds. The trough is located below the discharge box and is set at an inclined angle. The trough is mounted on the support device, which drives the trough to swing back and forth. Multiple sets of screen plates are arranged sequentially on the trough, and the multiple sets of screen plates are set with different mesh sizes; the seed germs to be separated are... The seeds are placed inside the hopper, and then a discharge device quantitatively discharges the seeds downwards. The discharged seeds fall onto the trough, and the trough is tilted back and forth by the support device, thus conveying and moving the seeds. During the conveying process, the seeds pass through the top of multiple sets of screen plates, which separate seeds of different sizes, improving the effect of separating and storing seeds of different sizes separately. At the same time, by absorbing air from the top of the trough, it is easier to separate the shell debris mixed in with the seeds. By reducing vibration during separation, the breakage rate of the seeds is reduced, and the effect of non-destructive separation is improved.

[0007] Preferably, the support device includes multiple sets of guide columns, a base, a crankshaft, a connecting arm, and a first motor. The multiple sets of guide columns are disposed on both sides of the outer wall of the tank. The guide columns are slidably mounted on the base. The crankshaft is rotatably mounted on the outer wall of the base. The end of the connecting arm is rotatably mounted on the outer wall of the crankshaft, and the other end of the connecting arm is rotatably connected to the side of the tank. The first motor is mounted on the outer wall of the base, and its output end is connected to the crankshaft. The first motor drives the crankshaft to rotate, and the crankshaft, after rotating, drives the tank to swing back and forth through the connecting arm. This causes the tank to shake and transport the buds, while simultaneously facilitating the separation of buds by multiple sets of screen plates, improving work efficiency, reducing vibration damage to the buds, and lowering the operating noise of the equipment.

[0008] Preferably, the discharge device includes a rotating shaft, multiple sets of conveying plates, and a second motor. The rotating shaft is rotatably mounted on the inner wall of the discharge box, and the multiple sets of conveying plates are circumferentially arranged on the outer wall of the rotating shaft. The second motor is mounted on the outer wall of the discharge box, and the output end of the second motor is connected to the rotating shaft. The buds in the hopper fall between the upper conveying plates under gravity. The rotating shaft is driven by the second motor to rotate, so that the multiple sets of conveying plates convey the buds downward and discharge them. By controlling the rotation speed of the rotating shaft, the discharge speed of the buds can be controlled, thereby improving the convenience of quantitative discharge of buds.

[0009] Preferably, it also includes multiple sets of guide channels and multiple sets of baffles. The multiple sets of guide channels are respectively set at corresponding positions below the multiple sets of screen plates, and the multiple sets of baffles are respectively installed on the inner sidewalls of the multiple sets of guide channels. The multiple sets of screen plates discharge the separated buds onto the multiple sets of guide channels, and the multiple sets of guide channels and multiple sets of baffles guide and transport the buds, improving the convenience of collecting buds of different sizes separately.

[0010] Preferably, it also includes multiple sets of baffles, all of which are installed at the bottom of the tank and are arranged between multiple sets of screen plates; by using multiple sets of baffles to block the bottom of the multiple sets of screen plates, the convenience of directional discharge of different buds is improved.

[0011] Preferably, it also includes a cover, which is installed on the top of the outer wall of the tank and is connected to an external vacuum cleaner; the external vacuum cleaner sucks air into the cover, thereby facilitating the absorption and separation of the shell debris mixed in the buds in the tank, improving the convenience of separation and use.

[0012] Preferably, the multiple sets of guide channels are set at an inclined angle to improve the convenience of guiding and transporting the buds.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the buds that need to be separated are placed inside the hopper, and then the buds in the hopper are discharged downward in a quantitative manner through the discharge device. The discharged buds fall onto the trough. The trough is tilted back and forth by the support device, thereby transporting and moving the buds. During the transport of the buds, they pass through the top of multiple sets of screen plates in sequence, so that the multiple sets of screen plates separate buds of different sizes, improving the effect of separating and storing buds of different sizes separately. At the same time, by absorbing air from the top of the trough, it is easy to separate the shell debris mixed in the buds. Due to the reduction of vibration separation, the breakage rate of buds is reduced, and the effect of non-destructive separation is improved. Attached Figure Description
