[0002] During the processing of Lotus Camellia, the tea leaves need to be transferred and then transported to the processing equipment. At this time, it is generally necessary to cooperate with an automatic weighing device to control the weight of the Lotus Camellia tea leaves at all times, so that the Lotus Camellia tea leaves can be transported accurately and the tea leaves can be transported in equal amounts. At this time, an automatic weighing device is needed to assist in transportation.

[0003] In actual work, the existing automatic weighing device technology is relatively complete and can meet the basic tea weighing and transportation needs, but there are still the following problems:

[0004] 1. In the actual weighing process, the amount of tea leaves falling from the chute cannot be controlled, which directly promotes the transportation method of tea leaves, making the amount of tea leaves falling uncontrollable, resulting in a large error in the weight of tea leaves. Even with the cooperation of a weighing device, only the approximate error value can be estimated, but the error cannot be avoided;

[0005] 2. In the process of tea leaves falling into the chute, if there is accumulated tea leaves above the chute, all of them will fall from the chute, resulting in a large error in the amount of tea leaves. In the process of pushing the tea leaves to fall, the amount of tea leaves above the chute cannot be controlled, which will cause a large error.

[0006] Therefore, the utility model provides an automatic weighing device for tea processing. Utility Model Content

[0026] 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.

[0027] like Figure 1-Figure 4 As shown, this embodiment provides a technical solution: an automatic weighing device for tea processing, comprising a support plate 1, a support rod 2 is fixedly connected to the bottom of the support plate 1, a transmission mechanism 5 is arranged at the bottom of the support plate 1, and the transmission mechanism 5 is composed of a transmission belt and a mounting table; a scale body 3 is fixedly installed on the top of the outer surface of the support plate 1, a storage frame 4 is arranged on the top of the scale body 3, and a blanking trough 8 is provided at the bottom of the storage frame 4 and the inner wall of the support plate 1; a uniform weight blanking structure 6 is arranged on the inner wall of the storage frame 4 and the bottom of the support plate 1, and an auxiliary anti-blocking structure 7 is arranged on one side of the uniform weight blanking structure 6; the uniform weight blanking structure 6 includes a rectangular frame 61, one side of the rectangular frame 61 The side is fixedly connected to one side of the storage frame 4, and a first motor 62 is fixedly installed on one side of the rectangular frame 61. The output end of the first motor 62 is fixedly connected to the first screw 63, and the outer surface of the first screw 63 is threadedly connected to a screw hole block 64. The top of the outer surface of the screw hole block 64 is fixedly connected to an L-shaped connecting rod 65, and one end of the L-shaped connecting rod 65 is fixedly connected to a push plate 66, and both sides of the outer surface of the push plate 66 are fixedly connected to flat groove plates 67. Under the action of the blanking cone frame 68 and the shielding plate 615, the tea leaves can be pre-stored in the blanking cone frame 68, and then the excess tea leaves on the top of the blanking trough 8 can be swept away under the action of the flat groove plate 67.

[0028] Further, such as Figure 2-Figure 4As shown: the bottom of the storage frame 4 is located below the blanking trough 8 and is fixedly connected to a blanking cone frame 68, the blanking cone frame 68 passes through the interior of the blanking trough 8 located on the support plate 1, the bottom of the support plate 1 is fixedly connected to a mounting plate 69, a second motor 610 is fixedly installed on one side of the mounting plate 69, a second screw 611 is fixedly connected to the output end of the second motor 610, the outer surface of the second screw 611 is threadedly connected to a threaded barrel 612, a shielding plate 615 is fixedly connected to one side of the outer surface of the threaded barrel 612, the shielding plate 615 can shield the bottom of the blanking cone frame 68, and the outer surface of the threaded barrel 612 is fixedly connected to an auxiliary plate 613, a limiting rod 614 is fixedly connected to one side of the outer surface of the auxiliary plate 613, and the limiting rod 614 is slidably inserted into the inner wall of the mounting plate 69. The blanking cone frame 68 can cooperate with the shielding plate 615, so that the tea leaves can be pre-dropped into the blanking cone frame 68, and the falling amount of the tea leaves can be controlled. When the tea leaves in the blanking cone frame 68 are fully loaded, the weight at this time is roughly the same, so that the weight of each drop is roughly the same, and under the action of the flat groove plate 67, the tea leaves above the blanking trough 8 and the blanking cone frame 68 can be shoveled away and the blanking trough 8 can be sealed, so as to ensure that no excess tea leaves fall during the blanking process.

[0029] The above scheme also has the problem that the blanking cone frame 68 is easily blocked during the blanking process due to the tea leaves falling too quickly. Figure 4 As shown: in the present scheme, the auxiliary anti-blocking structure 7 includes a rectangular card frame 71 and a rectangular sliding frame 73, the inner wall of the rectangular sliding frame 73 is slidably connected with a sliding block 74, one side of the outer surface of the sliding block 74 is fixedly connected with a connecting block 75, the top of the outer surface of the connecting block 75 is fixedly connected with a clearing point rod 76, and one side of the outer surface of the connecting block 75 is fixedly connected with an operating rod 77. Under the action of the operating rod 77, the sliding block 74 can be driven to slide on the inner wall of the rectangular sliding frame 73, and then the connecting block 75 and the clearing point rod 76 can be driven to move left and right, so that the clearing point rod 76 inserted into the blanking cone frame 68 can swing left and right, and then the tea leaves blocked in the blanking cone frame 68 can be shaken off.

[0030] The above scheme still has the problem that when the dredging sharp rod 76 is not in use, the normal use of the shield plate 615 is affected, such as Figure 4 As shown, one side of the outer surface of the rectangular sliding frame 73 is fixedly connected with a rectangular clamping block 72, and the rectangular clamping block 72 can be clamped into the inner wall of the rectangular clamping frame 71; one side of the outer surface of the rectangular clamping frame 71 is fixedly connected to one side of the outer surface of the shielding plate 615. By setting the rectangular clamping block 72 and the rectangular clamping frame 71, the rectangular sliding frame 73 can be installed and disassembled with one side of the shielding plate 615, so that when the clearing pointed rod 76 is not in use, the clearing pointed rod 76 can be removed to avoid affecting the normal use of the shielding plate 615.

[0031] Working principle:

[0032] like Figure 1-4 As shown:

[0033] When in use: start the first motor 62, so that the first motor 62 can drive the first screw 63 to rotate, and then drive the screw hole block 64 to move, so that the screw hole block 64 can drive the L-shaped connecting rod 65 to move, and then drive the push plate 66 to push the tea leaves to the drop chute 8;

[0034] At the same time, the flat groove plate 67 can push away the tea leaves on the top of the drop groove 8 and seal the top of the drop groove 8 to prevent excess tea leaves from falling;

[0035] At this time, the second motor 610 is started, so that the second motor 610 can drive the second screw 611 to rotate, and then drive the threaded cylinder 612 to move, so that the threaded cylinder 612 can drive the auxiliary plate 613 to move, and then the limiting rod 614 slides on the inner wall of the mounting plate 69, and the shielding plate 615 is separated from the bottom of the falling cone frame 68, so that the tea leaves can fall;

[0036] When the blanking cone frame 68 is blocked, the rectangular clamping block 72 is clamped into the rectangular clamping frame 71, and the operating rod 77 is pushed, so that the operating rod 77 can drive the sliding block 74 to slide on the inner wall of the rectangular sliding frame 73, and then drive the connecting block 75 and the dredging pointed rod 76 to move, so that the dredging pointed rod 76 dredges the inner wall of the blanking cone frame 68;

[0037] The tea leaves are then dropped onto the transmission mechanism 5 and transported away. At this time, the scale body 3 can measure and weigh the remaining tea leaves, and then the next cycle of dropping is carried out.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
