Description

Technical Field

[0001] The utility model relates to a classification device, in particular to a grapefruit size classification device. Background Art

[0002] When grapefruits are packaged and processed, they need to be sorted according to size, and a sorting device is required.

[0003] For example, a Chinese patent publication with publication number CN214268094U discloses an automatic rolling packaging machine for grapefruit processing, which includes a supporting device, and the supporting device includes a vertical block, a bracket and a vertical plate. There are two brackets in total. The upper surfaces of the two brackets are provided with horizontal blocks, and the front and rear ends of the lower surface of the horizontal blocks are fixedly connected to the upper surfaces of the two brackets respectively. There are two vertical plates in total, and the right surfaces of the two vertical plates are fixedly connected to the upper ends of the left surfaces of the two brackets respectively, so that the grapefruit to be packaged falls from the left end into between the two inclined plates, and the grapefruit smaller than the set size falls from between the two inclined plates onto the slide plate, and the grapefruit that meets the size continues to slide down from the two inclined plates, so as to achieve the effect of classification during sliding, which is convenient for direct classification and transportation after subsequent rolling packaging, saving the process of installing the size and then classifying after packaging, and improving production efficiency. The inclined plate also has the effect of preventing sliding out during rolling, so as to avoid the grapefruit falling out of the device and breaking during the rolling process, causing losses.

[0004] Some problems were found during the use of the above-mentioned existing rolling automatic packaging machine for grapefruit processing. First, the grapefruit is not a complete circle, and the grapefruit skin is soft and deformable. If the grapefruit only relies on the inclined inclined plate, it will often get stuck between the two moving plates and be difficult to move during the falling process. Secondly, only one size of grapefruit can be screened out at a time. If a more refined screening grapefruit size is required, the spacing between the two inclined plates needs to be adjusted multiple times for repeated screening. Utility Model Content

[0013] 1. Through the cooperation between the connecting plate and the connecting seat, the two supporting slide rails can be fixed together by bolts and columns, so that the two screening structures can be superimposed together. In the later stage, the number of screening structures can be increased as required to perform a single multi-specification classification operation on grapefruit.

[0022] In this embodiment, two V-shaped screening plates 206 cooperate with each other, and grapefruits are placed between the two V-shaped screening plates 206. If the grapefruit size does not meet the standard, it will directly fall from the gap between the two V-shaped screening plates 206 to the two V-shaped screening plates 206 below for screening. The two screening structures 2 are superimposed and connected by the connecting piece 3. Figure 1 In the figure, two screening structures 2 are superimposed, and screening can only be performed once. The number of screening structures 2 and connecting parts 3 can be increased to perform multiple screenings at a time. Starting the vibration motor 103 can drive the connecting platform 101 to vibrate. The screening structure 2 and the connecting part 3 are both fixed on the connecting platform 101, so that the connecting platform 101 vibrates. The inclined V-shaped screening plate 206 can effectively prevent the grapefruit from getting stuck.

[0023] Among them, in order to achieve the purpose of adjusting the distance between the two dovetail sliders 209, the present device is implemented by the following technical scheme: shock-absorbing legs 104 are fixedly installed at the positions near the four corner edges under the base 1, a fixed through hole 102 is opened on the base 1, connecting seats 205 are fixedly installed on both sides of the supporting slide rail 201, a bidirectional threaded rod 203 is rotatably installed in the dovetail slide groove 202, knobs 204 are fixedly installed at both ends of the bidirectional threaded rod 203, and the bidirectional threaded rod 203 is threadedly matched with the dovetail slider 209.

[0024] The connecting platform 101 can be supported in an inclined state by the shock-absorbing legs 104, and a certain shock-absorbing ability can be provided at the same time. The fixing through hole 102 and the knob 204 are fixed by bolts, so that the screening structure 2 is fixed on the base 1. Rotating the knob 204 can drive the bidirectional threaded rod 203 to rotate. The bidirectional threaded rod 203 and the dovetail slider 209 are threadedly matched, so that the rotation of the bidirectional threaded rod 203 can drive the dovetail slider 209 to move, thereby adjusting the distance between the two V-shaped screening plates 206.

[0025] Among them, in order to achieve the purpose of fixing the two screening structures 2, the present device is implemented by adopting the following technical scheme: rubber buffer pads 207 are fixedly installed on the opposite surfaces of the two V-shaped screening plates 206, and a limiting groove 208 is opened on the V-shaped screening plate 206, and the limiting groove 208 cooperates with the supporting slide rail 201. The connecting part 3 includes a column 301 and a connecting plate 302, and the connecting plate 302 is fixed on one side of the column 301 near the upper and lower end edges.

[0026] The rubber buffer pad 207 can provide a certain degree of protection for the grapefruit to prevent the grapefruit from falling between the two V-shaped screening plates 206 and being damaged. The limiting groove 208 cooperates with the supporting slide rail 201, and the upper supporting slide rail 201 can be used to clamp the lower V-shaped screening plate 206, limiting the V-shaped screening plate 206 to move only left and right. The connecting plate 302 cooperates with the connecting seat 205, and the two supporting slide rails 201 can be fixed together by bolts, thereby stacking the two screening structures 2 together.

[0027] The working principle and use process of the utility model: when using, the device needs to be placed in a suitable position, and according to the specifications of the grapefruit screening required, such as three specifications, it is necessary to continue to connect the connecting piece 3 Figure 1 Two screening structures 2 are superimposed on the basis, and then the knob 204 is rotated to drive the bidirectional threaded rod 203 to rotate. The rotation of the bidirectional threaded rod 203 can drive the dovetail slider 209 to move, thereby adjusting the distance between the two V-shaped screening plates 206, so that the distance between the V-shaped screening plates 206 on each screening structure 2 is in a suitable state, and the vibration motor 103 is started to drive the device to vibrate, and the grapefruits to be classified are placed between the two V-shaped screening plates 206 on the upper layer. If the size of the grapefruits does not meet the standard, they will directly fall from the gap between the two V-shaped screening plates 206 to the two V-shaped screening plates 206 below for screening. The grapefruits that meet the size will slide down along the V-shaped screening plates 206, thereby completing the size classification of the grapefruits.
