Description

Technical Field

[0001] This utility model relates to the field of food processing. More specifically, this utility model relates to a chestnut screening device. Background Technology

[0002] Chestnut, also known as chestnut (common name), chestnut (Hebei and other provinces), hairy chestnut (Henan), wind chestnut (Guangdong), is known as the "King of Dried Fruits" and is also called "ginseng fruit" abroad.

[0003] Existing chestnut screening devices typically consist of a box containing multiple inclined sieve plates. During use, chestnuts are poured in from the top of the box and sieved into different sizes by the plates. However, these devices suffer from several problems: First, the sieve plates are fixed within the box and do not vibrate. As a result, chestnuts, once on the plates, can only slide down the inclined plates by gravity, leading to low screening efficiency. Second, cleaning clogged sieve holes is extremely inconvenient. Therefore, this invention designs a chestnut screening device to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a chestnut screening device to solve the problems of low screening efficiency and poor ease of cleaning of the screen plate in the existing chestnut screening devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chestnut screening device, comprising a screening box, a top cover fixed to the top surface of the screening box by a set of bolts, a rotating rod rotatably connected to the bottom surface of the top cover, a motor fixedly connected to the top surface of the top cover, one end of the output shaft of the motor fixedly connected to the rotating rod, a set of guide rings fixedly connected to the circumferential side of the rotating rod, a screening mechanism placed inside the screening box, the screening mechanism comprising two fixed plates, the fixed plates being fixed to the screening box by a bolt, two elastic elements fixedly connected to the top surface of the fixed plates, a screen plate fixedly connected to the top of the elastic elements, a driven ring fixedly connected to the bottom surface of the screen plate, the rotating rod penetrating the screen plate and the driven ring, and a feed plate fixedly connected inside the screening box.

[0006] Preferably, the inner wall of the screening box is fixedly connected with multiple sets of support plates, each set consisting of two support plates located below the corresponding fixed plate to support the fixed plate.

[0007] Preferably, the elastic element includes an outer cylinder, an inner column, and a spring. The inner column is inserted into the outer cylinder and slides in cooperation with the outer cylinder. The spring is sleeved on the circumferential side of the inner column. The top end of the spring is fixed to the inner column, and the bottom end of the spring is fixed to the outer cylinder.

[0008] Preferably, the top surface of the guide ring and the bottom surface of the driven ring are provided with spaced protrusions and recesses, the protrusions of the guide ring can be inserted into the recesses of the driven ring, and the protrusions of the driven ring can be inserted into the recesses of the guide ring.

[0009] Preferably, a feed hopper is fixedly connected to the top cover, and multiple discharge holes are provided on the side of the screening box.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a design of a rotating rod, a guide ring, and a driven ring. A motor drives the rotating rod to rotate, which in turn drives the guide ring to rotate. During rotation, because both the guide ring and the driven ring have recesses and protrusions, and under the combined action of elastic elements, the rotation of the guide ring causes the driven ring to vibrate rapidly up and down, thereby causing the sieve plate to vibrate. The continuous vibration of the sieve plate enables rapid screening of chestnuts falling onto it. Compared to existing screening devices with a fixed sieve plate, this screening device significantly improves screening efficiency. 2. Through the design of the rotating rod, the guide ring and the driven ring, this utility model can drive multiple screen plates to vibrate together using only one motor, thereby effectively reducing the manufacturing cost of the device and improving its economic applicability; 3. Through the design of the top cover, rotating rod and screen plate, when the screen plate needs to be cleaned, all the bolts used to fix the top cover and fixing plate on the screening box are removed first, then the top cover can be lifted up and the screen plate can be completely removed from the screening box, so that the screen holes blocked on the screen plate can be cleaned. Compared with the existing screening devices where the screen plate is fixed in the box, this device significantly improves the convenience of cleaning. Attached Figure Description

Therefore, the above terms should not be construed as a limitation of this utility model.

[0017] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a chestnut screening device, including a screening box 1, a feed hopper 11 fixedly connected to a top cover 2, multiple discharge holes on the side of the screening box 1, a top cover 2 fixed to the top surface of the screening box 1 by a set of bolts, a rotating rod 3 rotatably connected to the bottom surface of the top cover 2, a motor fixedly connected to the top surface of the top cover 2, one end of the motor output shaft fixedly connected to the rotating rod 3, a set of guide rings 4 fixedly connected to the circumference of the rotating rod 3, a screening mechanism placed inside the screening box 1, the screening mechanism including two fixed plates 5, the fixed plates 5 and the screening box 1 fixedly connected by a bolt, two elastic elements 6 fixedly connected to the top surface of the fixed plates 5, a screen plate 7 fixedly connected to the top of the elastic elements 6, a driven ring 8 fixedly connected to the bottom surface of the screen plate 7, the rotating rod 3 passing through the screen plate 7 and the driven ring 8, and a discharge plate 9 fixedly connected inside the screening box 1.

[0019] Among them, such as Figure 2 As shown, multiple sets of support plates 10 are fixedly connected to the inner wall of the screening box 1. Each set of support plates 10 consists of two plates, which are located below the corresponding fixed plate 5 to support the fixed plate 5.

[0020] Among them, such as Figure 3 As shown, the elastic element includes an outer cylinder, an inner column, and a spring. The inner column is inserted into the outer cylinder and slides with it. The spring is sleeved on the circumferential side of the inner column. The top end of the spring is fixed to the inner column, and the bottom end of the spring is fixed to the outer cylinder.

[0021] Among them, such as Figure 3 and Figure 4 As shown, the top surface of the guide ring 4 and the bottom surface of the driven ring 8 are provided with convex and concave portions distributed at intervals. The convex portion of the guide ring 4 can be inserted into the concave portion of the driven ring 8, and the convex portion of the driven ring 8 can be inserted into the concave portion of the guide ring 4.

[0022] During the rotation of the guide ring 4, when the protrusion of the guide ring 4 is located in the concave part of the driven ring 8, the screen plate 7 is in a low position. When the protrusion of the guide ring 4 pushes up the protrusion of the driven ring 8, the screen plate 7 will move upward. At this time, the spring on the elastic element 6 will be stretched. Therefore, when the protrusion of the guide ring 4 returns to the concave part of the driven ring 8, under the reset action of the spring and the gravity of the screen plate 7 itself, the screen plate 7 will quickly return to the initial low position. This process repeats, and the screen plate 7 will vibrate rapidly.

[0023] The motor is started, and the motor drives the rotating rod 3 to rotate. The rotating rod 3 drives the guide ring 4 to rotate. During the rotation of the guide ring 4, because both the guide ring 4 and the driven ring 8 are provided with concave and convex parts, and under the joint action of the elastic element 6, the rotation of the guide ring 4 can drive the driven ring 8 to vibrate up and down rapidly, thereby driving the screen plate 7 to vibrate. The continuous vibration of the screen plate 7 can quickly screen the chestnuts falling on the screen plate 7. Compared with the existing screening device with the screen plate 7 fixed, this screening device can significantly improve the screening efficiency. After the multiple screen plates 7 screen the chestnuts into multiple grades, the chestnuts of different grades will be discharged from different discharge holes. The collection box is placed outside the discharge hole in advance to collect the chestnuts. When it is necessary to clean the screen plate 7, first remove all the bolts used to fix the top cover 2 and the fixing plate 5 on the screening box 1. Then the top cover 2 can be lifted up to remove all the screen plates 7 from the screening box 1. After that, the screen plates 7 can be cleaned and the blocked screen holes can be cleaned.

[0024] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
