[0034] Please refer to Figure 1 and Figure 2 In a preferred embodiment of the present application, a fruit grading device is provided, which comprises a grading bin 100, a drum screen 200 and a rotary driving mechanism 300.

[0035] A grading cavity 110 is formed in the grading bin 100, and the grading cavity 110 has a feeding port 120. Specifically, the feeding port 120 is arranged at the upper end of the grading cavity 110, and two guide plates that are inclined towards each other are arranged at the feeding port 120 to concentrate the position of the material during feeding.

[0036] The grading cavity 110 is provided with a screening structure, and the screening structure is provided with a material passing channel for the fruit material to pass through. The grading cavity 110 is formed with a grading discharge port 130 above one side of the screening structure. The drum screen 200 is rotatably installed in the grading cavity 110. The rotary driving mechanism 300 is used to drive the drum screen 200 to rotate, so that the fruit material that stays on the corresponding screening structure is output from the corresponding grading discharge port 130.

[0037] The fruit grading device provided by the present application uses the material passing channel of the screening structure to grade the material, and the material with a profile larger than the width of the material passing channel will stay on the screening structure. The rotary driving mechanism 300 continuously drives the drum screen 200 to rotate, so that the fruit material that stays on the corresponding screening structure is output from the corresponding grading discharge port 130, thereby realizing high-efficiency grading and discharging. The rotation of the drum screen 200 can drive the materials stacked together to roll and spread, without affecting the continuous grading of the fruit material and causing blockage and stagnation, so as to ensure the grading effect and efficiency. In addition, the residues and impurities will eventually fall to the lowest position, which can separate the residues and fruit materials compared with the prior art, and further improve the screening and grading effect.

[0038] Please refer to Figure 4 and Figure 5 In some embodiments of the present application, the screening structure is a screen plate 140 arranged in the grading cavity 110 and uniformly and spacedly arranged along a first preset direction. Figure 4The left-right direction is the direction along the axis of the drum screen 200. The material passing channel is defined by the adjacent and spaced sieve plates 140; the thickness direction of the sieve plate 140 is the left-right horizontal direction, and the thickness of the sieve plate 140 is much smaller than the diameter of the fruit, for example, the thickness of the sieve plate 140 is less than 1 / 10 of the diameter of the fruit, so that when the material on the sieve plate 140 driven by the drum screen 200 moves, the fruit material will not stably stay on the width of a single sieve plate 140, and the fruit material will be stuck between the sieve plates 140; when the diameter of the fruit is smaller than the spacing of the sieve plates 140, the fruit will directly fall down, and when the diameter of the fruit is larger than the spacing of the sieve plates 140, the fruit will stay between the sieve plates 140, thereby improving the accuracy of the classification, and there is no fruit material accumulation or pile to be pushed out of the classification discharge port 130, so that some fruits are not screened and discharged, resulting in poor classification effect. Referring to Figure 4 and Figure 7 The outer peripheral wall of the drum screen 200 is provided with a plurality of material pushing teeth plates 210 arranged uniformly and spaced apart along the first preset direction, and the material pushing teeth plate 210 is arranged in the first preset direction offset from the corresponding sieve plate 140, so that the material pushing teeth plate 210 can push the fruit material staying between the two sieve plates 140 out of the corresponding classification discharge port 130. The rotating drive mechanism 300 is used to drive the material pushing teeth plate 210 to rotate to output the fruit material staying on the sieve plate 140 from the corresponding classification discharge port 130. Compared with the classification by rolling down one by one, the present application uses a plurality of sieve plates 140 arranged to simultaneously screen and classify a large amount of material, greatly improving the classification efficiency, without the need to roll down the material one by one to realize the classification of fruit material as in the prior art.

[0039] Referring to Figure 4 and Figure 5 In some embodiments of the present application, the sieve plate 140 is an arc-shaped plate extending around the axis of the corresponding drum screen 200, and the material pushing teeth plate 210 is partially embedded in the material passing channel, that is, the material pushing teeth plate 210 is partially embedded between two sieve plates 140, so that it is easier to push the material stuck between the two sieve plates 140. The sieve plate 140 is an arc-shaped plate, and one end of the sieve plate 140 extending to the classification discharge port 130 is in a raised state, so that the fruit material needs to be pushed a distance and lifted to a certain height before it can be pushed out of the classification discharge port 130, so that the fruit has a certain length of pushing path and needs to be lifted, avoiding that the material that should fall is misclassified and discharged from the classification discharge port 130, so that the material can also fall from the material passing channel between the two sieve plates 140 in the moving path of pushing and lifting towards the classification discharge port 130 after not falling at the beginning, especially when the material pushing teeth plate 210 pushes three together towards the classification discharge port 130, the small fruit material stacked between the two larger fruit materials will roll down from the two sides and fall into the lower side, improving the accuracy of the classification and ensuring the classification effect.

[0040] Referring to Figure 2 , Figure 5 and Figure 6 , in some embodiments of the present application, the grading bin 100 is provided with a clamping plate 150, the sieve plate 140 is provided with a clamping block 141 extending towards the clamping plate 150, the clamping block 141 is provided with a clamping groove for clamping the clamping plate 150, thereby achieving installation of the sieve plate 140. Generally, the clamping plate 150 can be provided with multiple clamping blocks and arranged along the extension path of the sieve plate 140, thereby achieving multi-position clamping and positioning installation of the sieve plate 140. In addition, the sieve plate 140 can be adjusted in position along the first preset direction relative to the clamping plate 150, thereby adjusting the width of the material passing channel, and thereby achieving adjustment of the screening fruit diameter.

[0041] In some embodiments of the present application, the sieve structure and the drum screen 200 are arranged in multiple groups in the vertical direction, and the widths of the material passing channels of the multiple sieve structures gradually decrease from top to bottom, thereby achieving multi-stage screening. Referring to Figure 2 , the sieve structure and the drum screen 200 are arranged in three groups in the vertical direction, i.e., the material can be divided into three levels, and the slag and impurities will eventually pass through the material passing channel of the lowermost sieve structure and fall to the lowermost position, thereby achieving three-stage material separation and slag separation. A slag collection box can be provided at the lowermost position to collect the slag.

[0042] Referring to Figures 1 to 3 , in some embodiments of the present application, the grading bin 100 includes multiple module bins 101, the module bin 101 is provided with a module cavity, and the module bins 101 are stacked and spliced to form the grading cavity 110. The number of module bins 101 corresponds to the number of sieve structures and drum screens 200, i.e., the numbers of the module bin 101, the sieve structure and the drum screen 200 correspond to each other, and the sieve structure and the drum screen 200 are installed on the corresponding module bin 101. Thus, multiple module bins 101 can be provided as needed, thereby achieving multi-stage material separation, and the position of the sieve plate 140 is adjusted to adjust the width of the material passing channel, thereby achieving multi-dimensional material separation adjustment and improving the adjustment range and application range of the equipment.

[0043] It can be understood that, in specific embodiments of the present application, as shown in Figure 7 , the drum screen 200 is provided with a journal 230 at both ends, and referring to Figure 4 , the module bin 101 is provided with a bearing seat at the position of the journal 230, and the bearing seat is provided with a bearing for inserting the journal 230, thereby reducing the rotational friction of the journal 230.

[0044] Referring to Figures 2 to 6In further embodiments of the present application, the module bin 101 is provided with a guide plate 160, which is arranged below the grading discharge port 130 and extends downwardly and inwardly from the grading discharge port 130, so as to guide the material falling from the module bin 101 into the module bin 101 below, thereby avoiding the material falling directly from the grading discharge port 130 of the module bin 101 below without being screened by the screening structure below.

[0045] With reference to Figure 3 In further embodiments of the present application, the rotating drive mechanism 300 is an electric motor, and the output shaft of the electric motor is connected with a driving wheel 310, and the same end of all the drum screens 200 extends out of the grading bin 100 and is provided with a driven wheel 220, and all the driven wheels 220 are in transmission connection with the driving wheel 310, so that one driving mechanism can realize the rotation of all the drum screens 200, and the grading work of the whole machine device is realized, the structure is simplified, and the cost is saved. Specifically, the driven wheel 220 and the driving wheel 310 can be sprockets, and the driven wheel 220 and the driving wheel 310 can be in transmission connection through a chain.

[0046] With reference to Figure 3 In further embodiments of the present application, the module bin 101 is provided with a first interface 102 at the upper end and a second interface 103 at the lower end, and the grading discharge port 130 is formed on one side, and the directions of the grading discharge ports 130 of the two module bins 101 adjacent to each other are opposite, so that the directions of the module bins 101 adjacent to each other are staggered, which facilitates the arrangement of the subsequent material receiving structure, and the guide plate 160 enables the falling material to fall into the first interface 102 of the module bin 101 arranged oppositely below, so that the material can be accurately screened by the module bin 101 of the next stage. The first interface 102 of the module bin 101 above is in butt joint with the second interface 103 of the module bin 101 below, so as to realize the butt joint of the module bins 101, and a plurality of module bins 101 are spliced to form a continuous grading cavity 110. Specifically, as shown in Figure 5 The upper end of the module bin 101 is provided with a first splicing plate 104, and the lower end is provided with a second splicing plate 105, and the first splicing plate 104 and the second splicing plate 105 are provided with corresponding hole positions, and the hole positions of the first splicing plate 104 of the module bin 101 below are aligned with the hole positions of the second splicing plate 105 of the module bin 101 above and are connected and fixed by fasteners.

[0047] With reference to Figure 1 In further embodiments of the present application, the outer wall of the grading bin 100 is provided with a material receiving plate 170 below the grading discharge port 130, so as to guide the graded fruit materials into the subsequent collecting device.
