[0002] In the batching systems of all walks of life, materials can be divided into granular materials and powdery materials. The ton bag method is often used for material transfer or storage. Due to the long-term accumulation or water absorption of materials during the transfer and storage processes, caking phenomena will occur, resulting in the inability to unload materials normally at the ton bag feeding station, causing material accumulation in the ton bag feeding station and unable to feed into the next process. Therefore, it is necessary to design a ton bag feeding crushing and screening mechanism for use with ton bag feeding. Summary of the Invention

[0005] Furthermore, rubber anti-collision blocks are arranged on the outer side of the frame.

[0006] Furthermore, the vibration mechanism includes a housing with a triangular cross-section arranged in the middle of the upper end face of the screen, and a turbine vibrator arranged in the housing.

[0007] Furthermore, the number of screens arranged on the frame is an integer multiple of 2.

[0008] Furthermore, the elastic support includes a mounting plate positioned in the ton bag feeding station housing, a positioning pin shaft positioned on the mounting plate by means of a shock-proof gasket, and a spring positioned on the frame by means of a frame fixing seat and sleeved with the positioning pin shaft.

[0009] The beneficial effects produced by adopting the utility model: By improving the overall screening structure, it has the characteristics of simple structure and convenient installation, and can effectively avoid the phenomena of non-unloading and large block accumulation when discharging materials due to caking caused by long-term accumulation or water absorption of materials.

Specific embodiments

[0014] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0015] Refer to the attached Figures 1-3 , the feeding and screening device for the powder batching equipment is arranged inside the ton bag feeding station and below the ton bag cutter 1. The device includes a frame 3 positioned in the housing of the ton bag feeding station by means of an elastic support, a screen mesh 4 installed in the frame 3, and a vibration mechanism positioned in the middle of the upper end face of the screen mesh 4.

[0016] A rubber anti-collision block 3-1 is arranged on the outer side of the frame 3.

[0017] The vibration mechanism includes a housing 5 with a triangular cross-section arranged in the middle of the upper end face of the screen mesh 4 and a turbine vibrator arranged in the housing 5.

[0018] The number of screen meshes arranged on the frame 4 is an integer multiple of 2.

[0019] The elastic support includes a mounting plate 2-1 positioned in the housing of the ton bag feeding station, a positioning pin shaft 2-3 positioned on the mounting plate 2-1 by means of a shock-proof gasket 2-2, and a spring 2-5 positioned on the frame 3 by means of a frame fixing seat 2-4 and sleeved with the positioning pin shaft 2-3.

[0020] The feeding and screening device of the present utility model is installed inside the ton bag feeding station and below the ton bag cutter 1. The mounting plate 2-1 is welded and fixed to the inner wall of the housing of the ton bag feeding station, and the shock-proof gasket 2-2 and the positioning pin shaft 2-3 are positioned on the mounting plate 9.

[0021] The screen 4 is fixedly welded to the frame 3. Rubber anti-collision blocks 3-1 are installed on the outer side of the frame 3. The housing 5 of the turbine vibrator is installed at the top of the screen 4 (the turbine vibrator is installed inside the housing 5). Frame fixing seats 2-4 are welded at the four corners of the bottom of the frame 3 respectively. The frame 3 is connected through elastic supports to prevent the frame 3 from colliding with the housing of the bulk bag feeding station during vibration. Rubber anti-collision blocks 3-1 are installed around the frame 3. After the device is started, the turbine vibrator drives the screen 4 to vibrate, and the materials on the screen 4 are broken and fall into the lower silo.

[0022] When the present utility model is specifically implemented, the bulk bag feeding station starts feeding, and at the same time, this device is started. After the bulk bag enters the head silo, it falls onto the bulk bag cutter 1. The bulk bag cutter 1 cuts open the bulk bag, and the materials fall onto the screen 4. The turbine vibrator drives the screen 4 to vibrate, and the materials on the screen 4 are broken and fall into the lower silo, and then transferred to the next process.

[0023] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
