[0013] Figure 1 This is a schematic diagram of the structure of this utility model.

[0014] Figure 2 This is the left view of the present invention. Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] Figure 1 , 2 The components include a hopper 1, a wear-resistant layer 2, a buffer component 3, a bag clamping cylinder 4, a bag clamping arm 5, a first folding arm 5-1, a second folding arm 5-2, a connecting rod 5-3, a discharge cylinder 6, a bag pressing plane 6-1, a bag pressing part 7, and a bag guide component 8.

[0018] like Figure 1 , 2 As shown, this utility model is a material feeding buffer device, including a hopper 1. The inner wall of the hopper 1 is provided with a wear-resistant layer 2, and a buffer component 3 is provided in the inner cavity of the hopper 1. The buffer component 3 can buffer the material feeding from the hopper 1.

[0019] The discharge end of the hopper 1 is fixedly connected to the discharge cylinder 6. The outer side of the discharge cylinder 6 is constructed with a bag-pressing plane 6-1. The outer surface of the hopper 1 is also hinged to two mutually cooperating bag-clamping arms 5. The two bag-clamping arms 5 are connected by a bag-clamping cylinder 4 to realize the mutual linkage of the two bag-clamping arms 5. Each of the bag-clamping arms 5 is tensioned with a bag-pressing part 7, and the bag-pressing part 7 cooperates with the bag-pressing plane 6-1.

[0020] Furthermore, in practice, the bag-pressing section 7 uses a rubber plate, which has a certain degree of elasticity and can reliably press the bag opening after the bag is put on.

[0021] The discharge end of the discharge cylinder 6 is fixed with a bag guide 8 to guide the bag during bagging. There are two bag guides 8, which are located at both ends of the bottom surface of the discharge cylinder 6 along its length.

[0022] Understandably, the bag guide 8 is V-shaped, and its two ends are welded to both sides of the discharge cylinder 6 in the width direction. During the bagging operation, the bag is placed from the bottom of the hopper 1 upwards on the outside of the discharge cylinder 6. Due to the guiding effect of the bag guide 8, the bag can be accurately and reliably placed. After the bag is placed, the bag clamping cylinder 4 drives the bag clamping arm 5 to perform the bag clamping operation, clamping the bag opening onto the pressing plane 6-1 of the discharge cylinder 6.

[0023] Limiting parts are provided at the upper and lower ends of the discharge cylinder 6 to limit the bag pressing part 7. In actual production practice, the bag opening is pressed tightly by the bag pressing part 7. Since the bag pressing part 7 uses an elastic rubber plate, reliable pressing and fixing can be achieved.

[0024] The buffer component 3 adopts an inverted V-shaped structure. Specifically, the buffer component 3 is located in the middle of the hopper 1. During operation, when the material falls into the hopper, the material can slow down its falling speed through the buffer component 3, thereby reducing the impact force. Specifically, after the material falls onto the V-shaped surface of the buffer component 3, it is diverted and falls towards both sides of the buffer component 3, which can effectively reduce the impact force.

[0025] The lower part of the bag clamping arm 5 is a vertically bent section, and the bag pressing part 7 is fixedly connected to the lower vertically bent section of the bag clamping arm 5 with bolts.

[0026] The bag clamping arm 5 includes a first folding arm 5-1 and a second folding arm 5-2. The first folding arm 5-1 and the second folding arm 5-2 are vertically and fixedly connected. The connecting rod 5-3 is fixed at the connection between the first folding arm 5-1 and the second folding arm 5-2. The two ends of the bag clamping cylinder 4 are respectively connected to the corresponding connecting rod 5-3.

[0027] Furthermore, in order to facilitate the production of silo 1, silo 1 is configured as an upper and lower silo body, which are fastened together by bolts, and the discharge cylinder 6 is welded and fixed to the discharge port of the lower silo body.

[0028] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
