[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0028] The preferred embodiment of the feeding gate of the weighing feeder provided by the present invention is as follows: Figures 1 to 6 As shown: A feeding gate of a weighing feeder, comprising a rotating rod 5, both ends of the surface of the rotating rod 5 are fixedly connected with a second connecting block 7, one side of the second connecting block 7 is movably connected with a first connecting block 6, a shock absorbing assembly 8 is arranged inside the first connecting block 6, one side of the first connecting block 6 is fixedly connected with a gate body 1, a card slot 9 is provided on one side of the bottom end of the gate body 1, reserved slots 11 are provided at equal intervals on the top of one side of the gate body 1, an anti-loosening assembly 2 is provided on the top of the gate body 1 at one end of the reserved slot 11, a fixing bolt 13 is movably connected inside the reserved slot 11, the bottom end of the gate body 1 is movably connected with an adjustable plate 3, the upper end of one side of the adjustable plate 3 is fixedly connected with a card plate 4, and a bolt hole 12 is provided on the top of the card plate 4.

[0029] The shock absorbing assembly 8 includes a shock absorbing groove 804, which is opened at the upper end and the lower end of one side of the first connecting block 6. The inner wall of the shock absorbing groove 804 is fixedly connected to a damper 805, and one side of the damper 805 is fixedly connected to a sliding block 802. A shock absorbing spring 803 is wound around the surface of the damper 805 at one end of the sliding block 802. One end of the shock absorbing spring 803 is fixedly connected to the inner wall of the shock absorbing groove 804, and the other end of the sliding block 802 is fixedly connected to a shock absorbing column 800 extending to the outside of the first connecting block 6. 1. One end of the shock-absorbing column 801 is welded to one side of the second connecting block 7. When the material impacts the gate body 1, the first connecting block 6 and the second connecting block 7 will slide relative to each other. The shock-absorbing spring 803 is used to absorb the impact energy transmitted from the outside, and the damper 805 is used to consume the elastic potential energy of the shock-absorbing spring 803, thereby achieving the purpose of buffering and shock absorption, thereby preventing the external force from being directly transmitted to the rotating rod 5, resulting in the displacement between the rotating rod 5 and the second connecting block 7 and affecting the accuracy of the subsequent rotation and opening of the gate body 1.

[0030] In this embodiment, a sliding structure is formed between the sliding block 802 and the inside of the shock-absorbing groove 804. The cross-section of the sliding block 802 and the shock-absorbing groove 804 is cross-shaped. The sliding of the cross-shaped sliding block 802 and the inside of the shock-absorbing groove 804 is utilized to improve the smoothness of the sliding of the shock-absorbing column 801, and the sliding friction between the two can also consume a portion of the elastic potential energy of the shock-absorbing spring 803.

[0031] In this embodiment, rubber strips 10 are fixedly connected to one side of the first connecting block 6 at equal intervals, and one side of the rubber strip 10 is fixedly connected to one side of the second connecting block 7. The fixedly connected rubber strips 10 are used to improve the structural strength of the connection between the first connecting block 6 and the second connecting block 7, and the elastic deformation of the rubber strips 10 themselves can also improve the buffering and shock absorption effect between the first connecting block 6 and the second connecting block 7. Example 2

[0032] On the basis of embodiment 1, the preferred embodiment of the feeding gate of the weighing feeder provided by the present invention is as follows: Figures 1 to 6 As shown: the anti-loosening component 2 includes a fixing groove 204, which is opened at the top of the gate body 1 at one end of the bolt hole 12, and the inner wall of the fixing groove 204 is fixedly connected to a fixing spring 201, and one end of the fixing spring 201 is fixedly connected to an anti-loosening block 205 extending to the inside of the bolt hole 12, and one end of the top of the anti-loosening block 205 is fixedly connected to a lever 206 extending to the outside of the fixing groove 204. The elastic force of the fixing spring 201 is used to make the anti-loosening block 205 slide back to its original position, and then the top of the fixing bolt 13 can be limited and tightened to avoid vibration caused by the impact of the material, which may cause the threads of the fixing bolt 13 and the inside of the bolt hole 12 to loosen.

[0033] In this embodiment, a limiting groove 203 is provided on the inner wall of the fixing groove 204, and both sides of one end of the anti-loosening block 205 are fixedly connected with a limiting block 202 that slides with the inside of the limiting groove 203. The sliding of the limiting block 202 and the inside of the limiting groove 203 is utilized to improve the sliding stability of the anti-loosening block 205.

[0034] In this embodiment, the bottom end of the anti-loosening block 205 is in close contact with the top of the fixing bolt 13, and the length of the anti-loosening block 205 is less than the depth inside the fixing groove 204. The anti-loosening block 205 is used to facilitate the limit and anti-loosening of the top of the fixing bolt 13.

[0035] Furthermore, a sliding engagement structure is formed between the upper end of the card plate 4 and the inside of the card slot 9. The cross-section of the upper end of the card plate 4 and the inside of the card slot 9 is inverted convex. The engagement of the inverted convex card plate 4 with the inside of the card slot 9 improves the stability of the initial engagement installation between the adjustable plate 3 and the gate body 1.

[0036] In addition, a threaded fit is formed between the bottom end of the fixing bolt 13 and the inside of the bolt hole 12, and the bolt holes 12 and the fixing bolts 13 are distributed at equal intervals. The use of the equally distributed fixing bolts 13 and bolt holes 12 facilitates improving the firmness and stability of the mounting of the card plate 4 and the card slot 9.

[0037] The working principle and use process of the present invention are as follows: first, the card plate 4 is clamped into the card slot 9, and then the anti-loosening block 205 is driven to slide and compress the fixing spring 201 until it is completely inserted into the fixing slot 204 by toggling the toggle lever 206. Then, the fixing bolt 13 is inserted into the reserved slot 11 and screwed into the bolt hole 12. Then, the toggle lever 206 is released, and the elastic force of the fixing spring 201 is used to make the anti-loosening block 205 slide back to its original position, thereby limiting and tightening the top of the fixing bolt 13 to prevent the vibration caused by the impact of the material from causing the threads of the fixing bolt 13 and the bolt hole 12 to loosen, thereby achieving a firm installation between the gate body 1 and the adjustable plate 3.

[0038] At the same time, during the normal use of the gate body 1 and the adjustable plate 3, when the material impacts the gate body 1, the first connecting block 6 and the second connecting block 7 will slide relative to each other. At this time, the shock-absorbing column 801 and the sliding block 802 will slide to compress the shock-absorbing spring 803 and the damper 805. The shock-absorbing spring 803 is used to absorb the impact energy transmitted from the outside, and the damper 805 is used to consume the elastic potential energy of the shock-absorbing spring 803, thereby achieving the purpose of buffering and shock absorption, avoiding the external force from being directly transmitted to the rotating rod 5, resulting in displacement between the rotating rod 5 and the second connecting block 7, and affecting the accuracy of the subsequent rotation and opening of the gate body 1.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
