Description

Technical Field

[0001] The utility model relates to the field of fruit and vegetable processing, in particular to a fruit and vegetable classification conveyor belt. Background Technique

[0002] Fruits and vegetables are the abbreviations of fruits and vegetables. They refer to edible fruits and vegetables, which are a category of food relative to meat. When fruits and vegetables are processed and produced, conveyor belts are needed to transport them, and at the same time, the fruits and vegetables need to be classified by size during transportation to improve the quality of fruits and vegetables sold outside.

[0003] In the prior art, the size classification of fruits and vegetables is usually carried out by manual screening. This classification method is inefficient and very labor-consuming for staff. At the same time, when the staff work for a long time, they will feel tired, so that the staff will miss some fruits during the screening process. The missed small fruits will be mixed in the large fruits and are inconvenient to pick out, greatly reducing the classification accuracy.

[0004] Therefore, the technical personnel in this field provide a fruit and vegetable classification conveyor belt to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to provide a fruit and vegetable classification conveyor belt, which can classify and screen the mixed large and small fruits through a screening mechanism, and at the same time improve the screening effect of the screening mechanism through a vibration mechanism. The large fruits after screening enter the sleeve through the transfer box and are transported to the starting point of the conveyor belt body by the spiral conveyor rod for secondary screening to improve the screening accuracy.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fruit and vegetable classification conveyor belt includes a transfer box, two conveyor belt bodies and a screening box. Baffles are fixedly arranged on the front and rear end faces of the two conveyor belt bodies. Brackets are fixedly arranged on both sides of the lower end faces of the four baffles and at the lower ends of the front and rear end faces of the screening box. One motor is fixedly arranged on one side of the front end of the two baffles among the four baffles. A sleeve is fixedly arranged on one side of the transfer box. A spiral conveyor rod is rotatably arranged at the center of the bottom end face of the inner wall of the sleeve. A second motor is fixedly arranged at the center of the upper end face of the outer wall of the sleeve;

[0009] Through the above technical solution, fruits and vegetables can be transported by two conveyor belt bodies. During the transportation process, a screening mechanism can be used to screen small fruits into the screening box for storage. At the same time, large fruits can slide along the screening plate onto the next-level conveyor belt body for transportation. While facilitating the classification and screening of fruits and vegetables, the screened fruits and vegetables can be transported to the starting point of the conveyor belt for secondary classification through the sleeve and the screw conveyor rod inside it, reducing the occurrence of incomplete screening.

[0010] Furthermore, springs are fixedly arranged at both ends of the two clamping plates near both sides. One end of the four springs located at the upper and lower ends of the same clamping plate among the eight springs is fixedly connected to the upper and lower end faces of the inner walls of the two through grooves respectively. The screening plate is clamped inside the two clamping plates, and a plurality of screening holes are formed through the upper end face of the screening plate.

[0011] Through the above technical solution, small fruits can be screened into the screening box through the plurality of screening holes formed on the screening plate for collection, realizing the classification and screening of large and small fruits.

[0012] Furthermore, the extension plate is fixedly arranged at the center of one side of the screening plate, the C-shaped plate is fixedly arranged at the upper end of one side of the outer wall of the screening box, a third motor is fixedly arranged at the center of one side of the C-shaped plate, a rotating shaft is fixedly arranged at the output end of the third motor, and a rotating block is fixedly sleeved at the center of the outer wall of the rotating shaft.

[0013] Through the above technical solution, the third motor can be used to drive the rotating shaft and the rotating block to rotate, and the irregular rotating block continuously knocks on the extension plate to realize vibration screening, accelerating the screening speed.

[0014] Furthermore, a discharge port is formed through one side of the inner wall of the sleeve near the upper end, and a conveying plate is fixedly arranged at one side of the outer wall of the sleeve near the upper end.

[0015] Through the above technical solution, after the fruits and vegetables are transported to the top of the sleeve by the screw conveyor rod, they can be transported to the starting point of the conveyor belt body through the discharge port and the conveying plate for secondary screening.

[0016] Furthermore, the output ends of the two first motors are respectively fixedly connected to the rotating shafts of the two conveyor belt bodies, and the output end of the second motor is fixedly connected to the screw conveyor rod.

[0017] Through the above technical solution, the conveyor belt body can be driven by the first motor to transport fruits and vegetables, and the second motor can drive the screw conveyor rod to rotate, facilitating the transportation of fruits and vegetables to the discharge port.

[0018] Furthermore, a feed port is formed through one side of the upper end face of the transfer box, and the bottom end face of the inner wall of the transfer box is inclined towards one end of the sleeve.

[0019] Through the above technical solution, the screened fruits and vegetables can enter the transfer box along the feed inlet, and are transported into the sleeve through the inclined bottom end surface of the transfer box.

[0020] Furthermore, a box door is hingedly provided at the lower end of the center of one side of the screen box, and a handle is fixedly provided at the lower end of the center of one side of the box door;

[0021] With the above technical solution, the small fruits in the box door can be collected by lifting the box door to one side through the handle, so that the fruits and vegetables can be easily sorted according to their sizes.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a fruit and vegetable classification conveyor belt, which drives two conveyor belt bodies to rotate through two No. 1 motors, so that the fruits and vegetables on the conveyor belt body near the upper end can be transported to the screen plate, and the No. 3 motor drives the rotating block to knock the extension plate, so that the extension plate can vibrate the screen plate, and the vibration of the screen plate allows small fruits in the fruits and vegetables to fall into the screen box along the screen holes, and the large fruits slide onto the conveyor belt body near the lower end for transportation as the screen plate vibrates, thereby realizing the operation of classifying fruits and vegetables by size and avoiding the waste of physical effort and uneven screening caused by manual screening.

[0024] 2. The utility model proposes a fruit and vegetable classification conveyor belt. After the fruits and vegetables are screened on the lower conveyor belt, they fall into the transfer box along the feed port after being transported to the end, and are transported to the sleeve through the inclined bottom end surface of the inner wall of the transfer box. At this time, the spiral conveyor rod is driven to rotate by the No. 2 motor, so that the fruits and vegetables on the spiral conveyor rod move upward and escape from the discharge port, and are transported along the conveyor plate to the starting point of the conveyor belt body near the upper end for secondary screening. Through multiple screenings, the small fruits mixed in the large fruits can be effectively reduced, so that the classification accuracy is higher and the quality of the fruits and vegetables sold is better.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1-4 , an embodiment provided by the present invention: a fruit and vegetable classification conveyor belt, including a transfer box 1, two conveyor belt bodies 3 and a screening box 5. Baffles 4 are fixedly arranged on the front and rear end faces of the two conveyor belt bodies 3. Brackets 6 are fixedly arranged on both sides of the lower end faces of the four baffles 4 and at the lower ends of the front and rear end faces of the screening box 5. On one side of the front end of the two baffles 4 among the four baffles 4, a first motor 8 is fixedly arranged. A sleeve 7 is fixedly arranged on one side of the transfer box 1. A screw conveyor rod 12 is rotatably arranged at the center of the bottom end face of the inner wall of the sleeve 7. A second motor 9 is fixedly arranged at the center of the upper end face of the outer wall of the sleeve 7;

[0033] Through grooves 13 are respectively penetrated and opened at the upper ends of the front and rear end faces of the screening box 5. A screening mechanism 15 is arranged in the two through grooves 13, which can screen fruits and vegetables, so that small fruits in the fruits and vegetables can be screened into the screening box 5 along the sieve holes 1501. The screening mechanism 15 includes a sieve plate 1502 and two clamping plates 1504. A moving groove 14 is penetrated and opened at the upper end of one side of the inner wall of the screening box 5. A vibration mechanism 16 is arranged at the center of the upper end of one side of the outer wall of the screening box 5, which can vibrate the sieve plate 1502 through the rotating block 1605 and the extension plate 1601 to improve the screening rate of the sieve plate 1502. The vibration mechanism 16 includes an extension plate 1601 and a C-shaped plate 1602;

[0034] During use, first place the fruits and vegetables to be classified on the upper conveyor belt body 3, then start the two first motors 8 to drive the two conveyor belt bodies 3 to rotate. During the rotation of the upper conveyor belt body 3, the fruits and vegetables are transported to the sieve plate 1502, and the baffles 4 on both sides of the conveyor belt body 3 prevent the fruits and vegetables from slipping during transportation. Then start the third motor 1603 to drive the rotating shaft 1604 and the rotating block 1605 to rotate. By continuously pushing the extension plate 1601 with the rotating block 1605, the extension plate 1601 moves up and down continuously in the moving groove 14 to drive the sieve plate 1502 to move, and the spring 1503 on the clamping plate 1504 enables it to quickly reset when the sieve plate 1502 moves. During the reset process, vibration of the sieve plate 1502 can be achieved, and the screening process is accelerated through the vibration of the sieve plate 1502;

[0035] So that the smaller fruits and vegetables can be screened into the sieve box 5 through the multiple sieve holes 1501 at the upper end of the sieve plate 1502 for storage, and the small fruits in the sieve box 5 can be collected by opening the box door 17 through the handle. The larger fruits and vegetables slide onto the lower conveyor belt body 3 for transportation under the influence of the vibration of the sieve plate 1502. When the fruits and vegetables move to the end of the lower conveyor belt body 3, they enter the transfer box 1 along the feed port 2 and slide into the sleeve 7 along the inclined bottom end surface of the inner wall of the transfer box 1 towards the sleeve 7. Then start the second motor 9 to drive the spiral conveyor rod 12 to rotate, and through the cooperation of the spiral conveyor rod 12 and the sleeve 7, the fruits and vegetables that slide into the sleeve 7 are transported to the top. When the fruits and vegetables are transported to the discharge port 11, they slide onto the upper conveyor belt body 3 along the conveying plate 10 for secondary screening, preventing incomplete screening during the screening process from causing small fruits to be mixed in large fruits and affecting the accuracy of classification screening, which will affect the quality of the fruits and vegetables sold.

[0036] Working principle: The large fruits and small fruits are classified through the screening mechanism 15, so that the small fruits fall into the sieve box 5 along the sieve holes 1501 for collection, and the box door 17 facilitates the cleaning of the small fruits in the sieve box 5. At the same time, the screened fruits and vegetables can enter the sleeve 7 along the transfer box 1, and are transported to the discharge port 11 through the spiral conveyor rod 12 and slide onto the upper conveyor belt body 3 along the conveying plate 10 for secondary screening, preventing incomplete screening from causing small fruits to be mixed in large fruits and affecting the accuracy of classification screening.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
