Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice processing and packaging device. Background Art

[0002] Rice mainly contains water, carbohydrates, proteins, lipids, minerals and vitamins, etc. Water is an important chemical component of rice, which has a significant impact on the physiology of rice and is closely related to the storage and processing of rice.

[0003] A rice processing and packaging device is disclosed by China Publication No. CN217857308U, which relates to the technical field of rice processing. The utility model mainly comprises: a processing box, a box door is hinged on one side of the processing box, and a feed port is opened on the top of the processing box.

[0004] When the above technical solution is used to screen and grade rice, since the rice continuously enters the processing box through the feed port, the rice will accumulate on the filter plate after a period of screening, and the filter plate will be driven to move by the rotation of the cam. However, since the rice has been accumulated, the top layer of rice cannot be filtered by the filter plate, which has a negative impact on the rice screening operation. Utility Model Content

[0005] The utility model aims to solve the problem that the screening effect is low in the prior art because the screening is only performed by vibration of the filter plate, and a rice processing and packaging device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A rice processing and packaging device comprises a processing box, a feed hopper is fixedly connected to the processing box, a filter plate is slidably mounted on the processing box, a bracket is fixedly connected in the processing box, a guide rod penetrating the bracket is fixedly connected to the filter plate, a spring is welded between the bracket and the filter plate, a driving plate is fixedly connected to the bottom end of the guide rod, a connecting rod is fixedly connected between the two driving plates, and a motor is fixedly mounted on the processing box;

[0008] The processing box is provided with an auxiliary mechanism for improving the filtering efficiency of the filter plate on rice.

[0009] Preferably, the processing box is equipped with a box door, and the processing box is fixedly connected with supporting feet.

[0010] Preferably, the bracket is provided with a guide through hole for slidingly fitting a guide rod, and the spring is longitudinally movably fitted on the guide rod.

[0011] Preferably, the auxiliary mechanism includes a rotating shaft fixedly connected to the output end of the motor, a stirring rod located on the upper surface of the filter plate is fixedly mounted on the rotating shaft, a guide slider is slidably mounted on the processing box, a driven rack is fixedly connected to the guide slider, a driving gear is fixedly mounted on the rotating shaft, and a traction rod is connected between the guide slider and one of the drive plates.

[0012] Preferably, a movable through hole for the sliding sleeve rotating shaft is provided on the filter plate, and a guide groove for the sliding sleeve guiding slider is provided on the processing box.

[0013] Preferably, the pin shaft at the upper end of the traction rod is connected to the bottom end of one of the driving plates, and the pin shaft at the lower end of the traction rod is connected to the upper end of the guide slider.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] Compared with the prior art which only screens by vibration of the filter plate and has a poor screening effect, the utility model uses a rotating shaft to drive the traction rod to deflect back and forth through the meshing connection of the driving gear and the driven rack, and utilizes the position difference caused by the deflection of the traction rod and cooperates with the connecting rod to drive the two driving plates to move up and down vertically. The driving plate drives the filter plate to move up and down vertically through the guide rod, thereby increasing the vibration amplitude of the filter plate, and drives the stirring rod to break up the rice through the rotating shaft, thereby avoiding the accumulation of rice on the filter plate, which helps to improve the screening effect of the filter plate on rice.

A guide through hole for sliding the guide rod 5 is provided on the bracket 4. The guide through hole can be used to guide and limit the guide rod 5, thereby ensuring that the guide rod 5 can only perform linear motion in the vertical direction;

[0023] A spring 6 is welded between the bracket 4 and the filter plate 3. The spring 6 is longitudinally movably sleeved on the guide rod 5. The spring 6 can buffer and protect the vertical lifting of the filter plate 3.

[0025] The processing box 1 is provided with an auxiliary mechanism for improving the filtering efficiency of the filter plate 3 on the rice. The stirring rod 11 in the auxiliary mechanism is used to scatter the rice, and the position difference generated by the deflection of the traction rod 15 indirectly drives the filter plate 3 to be vertically lifted and lowered, thereby improving the filtering effect of the filter plate 3 on the rice.

[0026] Further explanation: the auxiliary mechanism includes a rotating shaft 10 fixedly connected to the output end of the motor 9, and a movable through hole for slidingly fitting the rotating shaft 10 is opened on the filter plate 3, and the movable through hole can provide a movable space for the movement of the filter plate 3 on the rotating shaft 10;

[0031] The rice is put into the processing box 1 through the feed hopper 2, and the motor 9 is started to drive the rotating shaft 10 to rotate forward and reversely. The rotating shaft 10 drives the stirring rod 11 to rotate forward and reversely to break up the rice. The rotating shaft 10 drives the driving gear 14 to rotate forward and reversely.
