[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] like Figures 1 to 5As shown, the hopper combination of the present embodiment includes a buffer hopper 21, a weighing hopper 22 and a memory hopper 23 from top to bottom. The buffer hopper 21, the weighing hopper 22 and the memory hopper 23 all include a hopper structure. The hopper structure includes a hopper body 11 and a hopper door 12. The hopper door 12 is a single-opening hopper door structure. The opening directions of the hopper doors 12 of the buffer hopper 21 and the weighing hopper 22 are opposite. The opening directions of the hopper doors 12 of the weighing hopper 22 and the memory hopper 23 are opposite. The bucket body 11 includes a front mounting surface 111, a rear mounting surface 112 and left and right side surfaces 113, which form a cylindrical structure with a large upper opening and a small lower opening, the upper opening is a material inlet, and the lower opening is a material outlet. One side surface 113 and the front mounting surface 111 and the rear mounting surface 112 connected thereto are rounded to form an arc-shaped contact portion 114. The bucket door 12 is hingedly mounted on the front mounting surface 111 and the rear mounting surface 112. The bucket door 12 is an arc-shaped structure, which cooperates with the arc-shaped contact portion 114. A scraper 115 is provided at the end of the left side surface 113, and the scraper 115 cooperates with the bucket door 12. A swing rod 121 is provided at one end of the bucket door 12, and the bucket door 12 is opened by toggling the swing rod 121.

[0040] like Figure 6 As shown, the hopper combination of this embodiment does not only refer to the different opening directions of the hopper door 12, but more importantly, the upper material falling position is located on the closed hopper door 12, so that the fish fillets will be gathered in groups on the right, left and right sides respectively. Then they will fall smoothly into the center of the hopper below. The material movement sequence moves in the order of abcdef. The three hopper structures are not arranged along the same vertical axis, but are adjusted so that the fish fillets can fall directly into the hopper door 12 without sticking to the walls around the hopper body 11. One of the left and right side surfaces 113 is almost vertical (the inclination angle range relative to the plane can be 80°-90°), and the other side surface is inclined inward (the inclination angle range relative to the plane is 50°-70°). This arrangement facilitates the connection of the arc-shaped contact portion 114.

[0041] The material weighing device of this embodiment includes:

[0042] Rack 30,

[0043] A loading tray 31 is disposed on the top of the frame 30;

[0044] A feeding conveyor 32 connected to the loading tray 31;

[0045] A hopper assembly is arranged at the outlet of the feeding conveyor 32, and the hopper assembly adopts the hopper assembly in Example 1;

[0046] The integral conveyor 33 is arranged below the hopper assembly for conveying materials; a water receiving plate 36 is arranged below the integral conveyor 33. A scraper 331 is rotatably arranged at one end of the integral conveyor 33 close to the lower barrel 340 to prevent the fish fillets adhering to the integral conveyor 33 from being sent out and to scrape off the fish fillets.

[0047] A material distributor 34, used for distributing materials;

[0048] The drive and control unit is used to control the operation of the equipment. The drive and control unit includes a buffer bucket opening module, a weighing bucket opening module, a memory bucket opening module, a weighing bucket weighing module, a weight calculation module and a distributor drive module. The opening module here is driven by a cylinder or a motor structure with a cross-turn, and the bucket door 12 is opened by toggling the swing rod 121. The weighing module is a weighing sensor structure, which is a conventional structure and is not shown in the figure. It is used to obtain the weight of the material in the current weighing bucket 22. The weight calculation module includes a control kernel, which not only counts the weight in the memory bucket 23 and the weighing bucket 22, but also selects the closest target bucket participating in the combination according to the set weight, and then transmits the opening information to its opening module, while controlling the operation of the whole machine. The distributor drive module selects the appropriate channel for release after receiving the material according to the data of the weight calculation module.

[0049] The material distributor 34 includes a material discharge barrel 340, a first guide frame 341, a second guide frame 342 slidably disposed on the first guide frame 341, a material receiving barrel 343 slidably disposed on the second guide frame 342, the second guide frame 342 is connected to a second driving rod 345, the material discharge barrel 340 is disposed at one end of the integral conveyor 33, the material receiving barrel 343 is connected to a first driving rod 344, a through hole 346 is disposed on the second guide frame 342, a qualified channel 347 and an unqualified channel 348 are installed at the lower part of the first guide frame 341, and the material discharge barrel 340 and the material receiving barrel 343 are connected to receive materials. Figures 10 to 12 As shown, three different working states of the distributor 34 are shown. Fig.10 To accept the material status, Fig.11 To be delivered to the qualified channel 347 state, Fig.12 It is transported to the unqualified channel 348 state.

[0050] In this embodiment, the integral conveyors 33 are symmetrically arranged in two groups. The material discharge barrel 340 is arranged between the two groups of integral conveyors 33 , and an intermediate material blocking plate 35 is arranged above the material discharge barrel 340 .

[0051] The middle baffle plate 35 includes a plurality of baffles 351. Here, a convex or concave surface can also be used. The baffles are used instead of a flat plate structure to reduce the contact area between the fish fillet and the middle baffle plate 35 and reduce adhesion. The receiving barrel 343 and the lower barrel 340 can also adopt a convex structure to reduce the contact area between the material and them.

[0052] The working principle of the present utility model is taken as an example of embodiment 3:

[0053] When in use, the fish fillet is placed on the loading plate 31, and the fish fillet is pushed to the feeding conveyor 32 manually or by a mechanism, and the fish fillet is sent to the buffer hopper 21 through the feeding conveyor 32. In order to ensure that the material is evenly dropped, to ensure that the material does not drop forward and backward, and to avoid material clamping, the buffer hopper 21 is designed. The fish fillet after passing through the buffer hopper 21 falls into the weighing hopper 22 with the bucket door 12 opened for weighing, and enters the memory hopper 23 after weighing and memorizes the weight data. At this time, there are multiple weighed memory hoppers 23 waiting to release the material. After the weighing hopper 22 is emptied, the weighing hopper door 12 is closed, and the buffer hopper 21 is opened again to let the fish fillet fall into the weighing hopper 22, and the material in the weighing hopper 22 is weighed. At this time, there are multiple weighing hopper structures waiting to release the material in the weighing hopper 21. According to the set weight, the weighing data in the memory hopper and the weighing hopper participate in the combined operation at the same time, and the selected hopper that meets the target weight value releases the material. Because there are multiple alternatives, the difference between the actual weight and the set value can be small. The combination scheme can be a combination of multiple memory buckets 23 (calculated individually by the weight in each memory bucket 23), a combination of multiple memory buckets 23 and corresponding weighing buckets 22 (a combination of multiple hoppers in the weight of the weighing bucket 22 and the memory bucket 23), and a combination of multiple memory buckets 23 and the weight of the weighing bucket 22 and the memory bucket 23 in the combination of multiple hoppers (since the memory bucket 23 is not selected individually and needs to be released, the memory bucket 23 and the weighing bucket 22 are released uniformly for combination).

[0054] The released fish fillets fall onto the integral conveyor 33 and are transported to the divider 34 via the integral conveyor 33. Products with qualified weight enter the qualified channel 347, and unqualified products enter the unqualified channel 348. If the weight of the material in a single hopper exceeds the set target weight or a hopper structure is not selected multiple times, it will be released and enter the unqualified channel 348.

[0055] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
