[0035] Example 1

[0036] like Figures 1-5 As shown, an intermittent material unloading device includes a feed bin 1, which is a conventional feed bin disclosed in the prior art. A drop bin 2 is installed at the bottom of the feed bin 1. Specifically, the discharge port of the feed bin 1 and the feed port of the drop bin 2 are fixedly assembled and connected by a plurality of bolts.

[0037] At the same time, in order to control the unloading of materials in the feed bin 1 and the unloading of materials in the discharge bin 2 during the working process, the material is unloaded intermittently during the working process to solve the problem that when the density of the material is small, it is easy to float in the bin. The intermittent unloading method ensures that the material can be fully settled before unloading. This method ensures accurate unloading and avoids the technical defects of uneven unloading caused by the low density of the material and the suspension of the material in the traditional unloading method.

[0038] Specifically, the intermittent material unloading device also includes a control mechanism for controlling unloading, and the control mechanism includes a first bin baffle 4 installed in the feed bin 1 to control unloading and a second bin baffle 5 installed in the blanking bin 2 to control unloading (the first bin baffle 4 and the second bin baffle 5 are located at the upper end positions in the feed bin 1 and the blanking bin 2).

[0039] At the same time, the first compartment baffle 4 and the second compartment baffle 5 swing respectively through the balance wheel assembly 3.

[0040] Specifically, the balance wheel assembly 3 includes a gravity balance wheel 31 (the gravity balance wheel 31 is located on the outside of the corresponding feed bin 1 and the drop bin 2), and the gravity balance wheel 31 is fixedly connected to the rotating shaft 37 through the balance wheel connecting arm 32 (according to the existing method, the two ends of the rotating shaft 37 are rotatably connected to the bearing seat 33, and the bearing seat 33 is fixedly installed on the side wall of the corresponding feed bin 1 and the drop bin 2); the rotating shaft 37 is rotatably connected in the corresponding feed bin 1 and the drop bin 2.

[0041] At the same time, a driven balance wheel 36 is fixedly connected to the rotating shaft 37 ; specifically, the driven balance wheel 36 is fixedly connected to a balance wheel arm 35 , and the balance wheel arm 35 is fixedly connected to the rotating shaft 37 .

[0042] The control mechanism also includes a pusher assembly 7 for tilting the balance assembly 3. The pusher assembly 7 is mounted between the upper and lower balance assemblies 3. When the pusher assembly 7 tilts upward and pushes the driven balance 36 upward, the driven balance 36 is fixed to the shaft 37 via the balance arm, while the first and second compartment baffles 4 and 5 are fixed to their respective shafts 37.

[0043] Therefore, at this point, the first bin baffle 4 rotates along with the rotating shaft 37. As the first bin baffle 4 rotates, material continuously falls from the first bin baffle 4 (after the first bin baffle 4 rotates, the gap between the first bin baffle 4 and the feed bin 1 gradually increases). By controlling the rotation amplitude of the first bin baffle 4, the material discharge is controlled. This allows for the controlled discharge of low-density, easily suspended materials. Under this control, the suspended materials gradually settle.

[0044] Similarly, when the push wheel assembly 7 pushes the driven balance wheel 36 to the bottom, the second bin baffle 5 is controlled to flip, thereby further controlling the unloading of materials.

[0045] When the second bin baffle 5 and the first bin baffle 4 are flipped to a horizontal state, in order to prevent the second bin baffle 5 and the first bin baffle 4 from continuing to flip, the upper ends of the above-mentioned feed bin 1 and discharge bin 2 are respectively fixedly connected with a horizontal baffle 6 that cooperates with the first bin baffle 4 and the second bin baffle 5; when the first bin baffle 4 and the second bin baffle 5 are flipped to a horizontal state, the first bin baffle 4 and the second bin baffle 5 are blocked at the bottom position of the horizontal baffle 6 (at this time, they are in a stopped unloading state).

[0046] Example 2

[0047] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the push wheel assembly 7 includes a push wheel 72; the push wheel assembly 7 also includes a reduction motor 73 that drives the push wheel 72 to flip. The reduction motor 73 is equipped with a reduction motor support bracket, and the reduction motor 73 support bracket is fixedly installed at the lower end of the side wall of the blanking bin 2.

[0048] Specifically, the push wheel 72 is fixedly connected to the push wheel connecting arm 71, and the output shaft of the reduction motor 73 is fixedly connected to the push wheel connecting arm 71. During operation, when the reduction motor 73 drives the push wheel connecting arm 71 to rotate, the push wheel connecting arm 71 drives the push wheel 72 to flip until it contacts the driven balance wheel 36 in the upper position. The driven balance wheel 36 then drives the rotating shaft 37 to rotate in the manner described above, and then controls the first bin baffle 4 to flip and unload. When the push wheel 72 continues to flip until it contacts the driven balance wheel 36 in the lower position, the driven balance wheel 36 then drives the rotating shaft 37 to rotate in the manner described above, and then controls the second bin baffle 5 to flip and unload.

[0049] Through the above mode, the material is discharged in a control mode, and the first bin baffle 4 and the second bin baffle 5 are turned over in an alternating mode, so that the material is intermittently present in the feeding bin 1 or the discharging bin. For example, during the turning process of the second bin baffle 5, the first bin baffle 4 is horizontally static, and vice versa. The first bin baffle 4 is turned over to discharge the material. In this way, intermittent discharge is realized, and sufficient time is reserved for the settlement of the material.

[0050] In actual work process, the turning angle of the first bin baffle 4 and the second bin baffle 5 can be controlled by the turning range of the gravity balance wheel 31 (the pushing range of the push wheel 72 is controlled by the reduction motor), so as to further control the discharge mode.

[0051] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the scope of the present application should also be within the protection scope of the present application.
