Description
Technical Field
[0001] This utility model relates to the field of vegetable particle screening machines, and more particularly to vegetable particle material screening machines. Background Technology
[0002] In modern agriculture and the food processing industry, vegetable processing is becoming increasingly sophisticated. As consumers demand higher quality vegetable products, such as dried vegetables, vegetable powder, and frozen vegetable granules, the production of these products requires precise screening of the vegetable granules. Traditional screening methods, such as manual screening, are not only inefficient but also struggle to guarantee accuracy. In large-scale vegetable processing, manual screening cannot meet the ever-growing market demand.
[0003] Existing screening machines mainly rely on the excitation force generated by a vibrating motor. The vibrating motor is mounted on the base or side wall of the screening machine, and when the motor runs, it generates vibrations in the vertical, horizontal, or inclined directions. Vegetable granules are placed on the screen, and under the action of vibration, the material moves in a jumping motion on the screen.
[0004] However, in actual use, vegetable particles come in various shapes, and irregular particles may form bridging phenomena on the screen, meaning that particles support each other and get stuck at the screen holes, hindering the passage of other particles and affecting the screening effect. Broken or long vegetable particles are more prone to bridging. Therefore, a vegetable particle material screening machine was developed to address the above-mentioned problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 2-4This utility model provides an embodiment of a vegetable granule material screening machine, including a base 1, a housing 2 fixedly connected to the top of the base 1, a transmission mechanism 5 externally mounted on the base 1, and a screening mechanism 6 internally mounted on the base 1. The transmission mechanism 5 includes a support, a motor, and a rotating shaft. The support is fixedly connected to the front surface of the base 1. The motor serves as a power source, and its output end is fixedly connected to the rotating shaft. The motor is fixedly connected to the outer wall of the support, and the rotating shaft is fixedly connected to the output end of the motor. A limit block is fixedly connected to the outer wall of the rotating shaft. The limit block, fixedly connected to the outer wall of the rotating shaft, limits the position of relevant components during the rotation of the rotating shaft, ensuring proper alignment with the rotating shaft. Other components of the assembly (such as sleeve 611, etc.) operate within a predetermined motion trajectory. The screening mechanism 6 includes sleeve 611, which is fitted onto the outer wall of the rotating shaft. The inner wall of sleeve 611 is adapted to the shape of the rotating shaft, ensuring that sleeve 611 can rotate stably with the rotating shaft. A bearing 612 is fixedly connected to the outer wall of sleeve 611, and a base 613 is fixedly connected to the outer wall of bearing 612. A screen 615 is fixedly connected to the outer wall of sleeve 611. When sleeve 611 rotates, screen 615 rotates accordingly. By utilizing different mesh gaps, vegetable particles are graded and screened. A rotating rod 618 is rotatably connected to the inner wall of the screen 615. A gear 6111 is fixedly connected to the top of the rotating rod 618. An elliptical block 619 is fixedly connected to the outer wall of the rotating rod 618. The elliptical block 619 vibrates the surface of the screen 615 during movement. A limiting rod 614 is fixedly connected to the inner wall of the box 2. On one hand, the back of the box 613 is inserted into the limiting rod 614 fixedly connected to the inner wall of the box 2 to prevent the chassis 613 from rotating with the sleeve 611. The back of the chassis 613 is inserted into the outer wall of the limiting rod 614. A connecting plate 616 is fixedly connected to the outer wall of the chassis 613. A semi-tooth ring 617 is fixedly connected to the outer wall of the connecting plate 616. 6111 rotates intermittently along the semi-tooth ring 617, thereby driving the rotating rod 618 and the elliptical block 619 to move. The inner wall of the sleeve 611 is adapted to the shape of the rotating shaft. The outer wall of the gear 6111 meshes with the semi-tooth ring 617. There are two sets of screening mechanisms 6, which are symmetrically arranged in the two sets of material chambers. The outer wall of the rotating rod 618 is in contact with the mesh surface of the screen 615. This symmetrical arrangement allows the screening machine to screen a large number of vegetable particles at the same time, further improving the screening efficiency. The elliptical block 619 is made of hard silicone. There are three sets of elliptical blocks 619 symmetrically arranged on the outer wall of the rotating rod 618.
[0025] Reference Figure 1 , Figure 4The top of the box 2 has a feed inlet 4, and the inside of the box 2 has two sets of material chambers with a connecting port between them. The inner wall of the connecting port is fitted with a plate 7, and the inner wall of the material chamber is threaded with a box cover 3. The box cover 3 is made of transparent acrylic sheet. The transparent acrylic sheet of the box cover 3 facilitates the staff to observe the internal screening situation at any time, identify problems in time and adjust the screening operation. On the other hand, it plays a sealing role during the screening process to prevent vegetable particles from splashing and ensure the cleanliness of the screening environment. The outer wall of the rotating shaft is fitted with a pulley 9, and the outer wall of the pulley 9 is connected to a drive belt 11. The mesh gap of the upper screen 615 is larger than that of the lower screen 615. When the motor drives the rotating shaft to rotate, the power can be synchronously transmitted to the two sets of rotating shafts in the box 2 through the transmission action of the pulley 9 and the drive belt 11, so as to realize the synchronous operation of the two sets of screening mechanisms 6 and ensure the consistency and stability of the screening process.
[0026] Working principle: Workers feed vegetable granules into the feed inlet 4 at the top of the housing 2, start the motor, and the motor drives the bearing 612 at the output end to rotate. When the bearing 612 rotates, it drives the two sets of bearings 612 inside the housing 2 to rotate under the action of the pulley 9 and the connecting belt. The bearings 612 drive the screening mechanism 6 on the outer wall to operate. When the sleeve 611 rotates, it drives the four sets of screens 615 on the outer wall to rotate, thereby blocking large vegetable granules. Small vegetable granules will fall into the screening mechanism 6 at the lower end. At this time, the screens 615 at the lower end rotate to prevent small vegetable granules from sticking together. Simultaneously, the sleeve 611 is connected to the end of the... A base 613 is connected to the bearing 612. The base 613 is inserted into the limiting rod 614 on the inner wall of the box 2 to prevent the base 613 from rotating. The rotating rod 618 and gear 6111 are connected by the inner wall of the screen 615. When rotating, the gear 6111 will rotate intermittently along the half-tooth ring 617, thereby vibrating the surface of the screen 615 to prevent the vegetable particles from sticking together. At the same time, the entire screen 615 mechanism can be pulled out. Under the action of the base 613, the vegetable particles inside can be taken out together to prevent the vegetable particles from scattering inside the box 2 and being difficult to collect. Meanwhile, the box cover 3 is transparent, so the screening situation inside can be observed at any time.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
