Description

Technical Field

[0001] The utility model relates to the technical field of fruit processing, in particular to a fruit conveyor belt with a screening function. Background Art

[0002] During the fruit processing process, conveyor belts can transport fruits from picking, cleaning, grading, packaging and other links to improve production efficiency. The basic function of conventional conveyor belts is to transport materials and products. The sorting and inspection of products still have to be done manually. There are still differences in manual inspection of product weight and product size, which can easily cause the quality of products leaving the factory to be substandard and affect sales. In addition, manual sorting wastes time, and the increased manual sorting processing also increases costs.

[0003] Existing technologies, such as publication number CN213161960U, provide a conveyor belt with a screening function, including a main belt body, a weighing sensor fixedly connected to the inner side of the top center of the main belt body, a pressure sensor fixedly connected to the top of the fixed rod, a piston fixedly connected to a first push rod, and a first push plate fixedly connected to the side of the first push rod. In the present utility model, firstly, by combining the weighing sensor installed on the top of the main belt body with the pneumatic push plate fixedly connected to the outside of the main belt body, pneumatic sorting of products that do not meet the weight requirements is achieved, and they are recycled and processed through another level of conveyor belt. The recycled products can be reprocessed. By using the bracket installed on the top of the main belt body and the pressure sensor installed on the top of the bracket, products that exceed the standard height can be discovered and sorted through another set of pneumatic push plates. The two sets of devices can improve the overall product quality and replace manual sorting, which is worthy of vigorous promotion.

[0004] This solution combines a weighing sensor mounted on the top of the main conveyor with a pneumatic push plate fixed to the outside of the main conveyor to pneumatically sort products that fail to meet weight requirements. However, for some fruits, which are naturally round, the pneumatic push plate can easily cause the fruit to deviate from its intended trajectory during the push, preventing it from moving to the designated location. Furthermore, the use of multiple sensors increases the overall maintenance cost of the equipment. Therefore, we propose a fruit conveyor with a screening function. Utility Model Content

[0005] The purpose of the utility model is to provide a fruit conveyor belt with a screening function, which solves the problem of insufficient roundness and stability of the transport surface of conventional conveyor belts.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A fruit conveyor belt with a screening function comprises a support frame, wherein a conveying mechanism is provided inside the support frame for conveying screened fruits;

[0008] The support frame is provided with an adjustment structure inside for adjusting the screening size;

[0009] The conveying mechanism includes slide rails, which are respectively opened on both sides of the support frame. A conveying rod is provided inside the support frame, and both ends of the conveying rod are respectively slidably connected to the slide rails and are evenly distributed inside the support frame. Chains are respectively provided on both sides of the support frame, and the chains are connected to the corresponding ends of the conveying rods. The chains are driven by sprockets rotatably connected on both sides of the support frame. The outer wall of the support frame is connected to a motor through a mounting frame, and the motor is used to drive the sprocket.

[0010] Preferably, a discharge chute is connected to the support frame at a position below the top of the conveying rod for discharging the screened smaller fruits.

[0011] Preferably, there are four sprockets, and two sprockets are grouped together and distributed on both sides of the support frame, and a rotating rod is connected between the sprockets.

[0012] Preferably, the adjustment structure includes a transport plate, and the transport plate is respectively connected to the outer wall of each conveying rod.

[0013] Preferably, the transport plate consists of an adjusting groove, an adjusting block, a linkage rod, a support plate, a slide plate, and a hinged rod. The adjusting groove is opened on the inner wall of the conveying rod, the adjusting block is slidably connected to the inner wall of the adjusting groove, the support plate is connected to the outer wall of the conveying rod, the slide plate is slidably connected to both sides of the inner wall of the support plate, the hinged rod is hinged at the positions between the two sides of the adjusting block and the slide plate, the linkage rod is connected to the adjusting block, and extends to the outside of the adjusting groove.

[0014] Preferably, the adjustment structure further includes an adjustment ring, which is arranged on one side of the outside of the support frame, and the inner wall of the adjustment ring is slidably connected to the linkage rod.

[0015] Preferably, the inner wall of the adjustment ring is connected to a support frame, and one side of the support frame is connected to an electric cylinder for driving the support frame to move.

[0017] 1. The utility model starts a motor to drive the sprocket to rotate, and drives the conveying rod to move through the transmission chain to facilitate the transportation of fruits. By arranging the conveying rod instead of the conventional conveyor belt, the fruits are placed on the conveying rod for transportation. During the transportation process, the fruits can be screened according to the size of the gaps between the conveying rods, thereby greatly improving the screening efficiency, reducing the investment in manual screening and labor costs, and not using sensors and other equipment for auxiliary screening, which greatly reduces the cost of later maintenance and is conducive to promotion.

[0018] 2. The utility model drives the adjustment block to move through the linkage rod, and then limits the relative position through the connection relationship between the slide and the support plate, so that the hinge rod can be expanded or retracted to adjust the expansion range of the slide. In this way, the distance between the transport plates can be easily adjusted to facilitate the adjustment of the size of the screening. BRIEF DESCRIPTION OF THE DRAWINGS
