Description

Technical Field

[0001] This utility model relates to the field of hopper transfer technology, and in particular to an automatic clamping mixing arm. Background Technology

[0002] In the process of transferring and processing large quantities of materials, materials need to be loaded into hoppers, and then the hoppers can be used for continuous and controllable feeding. The hoppers loaded with materials are transported to the hoisting position by a transport trolley. The hoisting equipment separates the hoppers from the transport trolley and hoists the hoppers to the feeding position for feeding preparation.

[0003] In existing hoisting equipment, the hopper is mainly connected and fixed below the hoisting equipment by lifting rings or hooks. This fixing method affects the stability of the hopper connection, and the hopper cannot automatically connect with the lifting rings or hooks on the hoisting equipment, requiring manual intervention. This not only increases labor costs, but also poses a high risk to manual operation in this environment. In order to improve the stability of the hoisting equipment in connecting and fixing the hopper, an automatic clamping mixing arm is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic clamping mixing arm to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic clamping mixing arm, comprising a clamping mixing arm for clamping and fixing the hopper body, wherein the clamping mixing arm includes:

[0006] U-shaped frame;

[0007] The support member is disposed on the inner walls of both sides of the U-shaped frame, so that the U-shaped frame supports the hopper body through the support member;

[0008] The clamping component is positioned above the bearing components on both sides of the U-shaped frame to clamp and position the hopper body within the U-shaped frame.

[0009] Preferably, the U-shaped frame includes a crossbeam, and longitudinal beams are fixedly connected to both ends of the crossbeam, with the longitudinal beams arranged perpendicularly to the front of the crossbeam.

[0010] Preferably, the bearing component includes left and right limiting blocks, which are symmetrically and fixedly connected to opposite sides of two longitudinal beams. The left and right limiting blocks located on the same side of the longitudinal beams are two spaced-apart blocks.

[0011] Preferably, two rear limiting blocks are symmetrically fixedly connected to the side of the crossbeam near the longitudinal beam, and a hopper positioning detection switch fixed to the front of the crossbeam is provided between the two rear limiting blocks.

[0015] A servo motor is connected to one end of a lead screw and fixed to a longitudinal beam, so that the servo motor drives the lead screw to rotate.

[0016] Preferably, the clamping head includes a connecting nut seat that is threaded into the outer wall of the lead screw, a connecting rod that is parallel to the left and right limit blocks and fixed to the outer wall of the connecting nut seat, and a conical plug that is fixedly connected to the end of the connecting rod away from the connecting nut seat.

[0017] Compared with the prior art, the technical effects of this utility model are as follows:

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-4 An automatic clamping mixing arm is shown, comprising a clamping mixing arm 200 for clamping and fixing a hopper body 100. The bottom of the hopper body 100 is tapered with a gradually decreasing size along the downward direction. Hopper ear tubes 101 are fixedly connected to the top of both sides of the hopper body 100. The two ends of the hopper ear tubes 101 are concave inward, which can cooperate with support members and clamping members to achieve support and locking positioning of the hopper body 100 on the clamping mixing arm 200. The clamping mixing arm 200 includes a U-shaped frame. The hopper body 100 consists of a support member and a clamping member. The support member is located on the inner walls of both sides of the U-shaped frame, allowing the U-shaped frame to support the hopper body 100. The clamping member is located above the support member on both sides of the U-shaped frame, clamping and positioning the hopper body 100 within the U-shaped frame. Since the clamping mixing arm 200 is funnel-shaped (wider at the top and narrower at the bottom), initially it is located at the bottom. When the hopper body 100 is moved to the position of the clamping mixing arm 200 by the transport trolley, the hopper body 100 can be straightened... The material is inserted into the inner side of the clamping mixing arm 200, so that the hopper ear tubes 101 on both sides of the hopper body 100 are positioned above the carrier on the clamping mixing arm 200. The external drive system lifts the clamping mixing arm 200 upward. Since the carrier supports the hopper ear tubes 101 on both sides of the hopper body 100 from below, the hopper body 100 can be lifted upward, allowing the hopper body 100 to detach from the transport trolley. After the hopper body 100 is completely detached from the transport trolley, the clamping device can be operated to clamp the two ends of the hopper ear tubes 101 to achieve the position between the hopper body 100 and the U-shaped frame. This ensures that the relative position between the hopper body 100 and the clamping mixing arm 200 is fixed, keeping the hopper body 100 stable during the transfer process with the clamping mixing arm 200. The entire process requires no human intervention and can automatically achieve the lifting, clamping, positioning, and rotation of the hopper body 100, making the entire transfer process of the hopper body 100 more stable, safe, and efficient.

[0026] The U-shaped frame includes a crossbeam 201, with longitudinal beams 202 fixedly connected to both ends of the crossbeam 201. The longitudinal beams 202 are vertically arranged along the front of the crossbeam 201. The crossbeam 201 and the two longitudinal beams 202 are vertically connected and fixed to form a U-shaped frame, so that the U-shaped frame has a port for the hopper body 100 to be inserted, and at the same time provides stable support for the hopper body 100 and its components.

[0027] The supporting components include left and right limiting blocks 203, which are symmetrically fixedly connected to opposite sides of two longitudinal beams 202. Two left and right limiting blocks 203 are spaced apart on the same side of the longitudinal beams 202. During the upward movement of the U-shaped frame, the left and right limiting blocks 203 contact the bottom end of the hopper ear tube 101 and lift upwards, thereby supporting and lifting both ends of the hopper ear tube 101, improving the stability of the lifting of the hopper body 100. Two rear... The limit block 204 has a hopper positioning detection switch 205 fixed to the front of the crossbeam 201 between the two rear limit blocks 204. The rear limit blocks 204 can block and limit the insertion position of the hopper body 100 when the transport trolley drives the hopper body 100 into the U-shaped frame in the initial stage, so as to avoid direct collision with the crossbeam 201. At the same time, the hopper positioning detection switch 205 can monitor whether the hopper body 100 is in position within the U-shaped frame, thereby ensuring the accuracy of the hopper body 100's positioning position within the U-shaped frame.

[0028] The clamping components include a lead screw 206, two clamping heads 208, and a servo motor 207. The lead screw 206 is rotatably mounted inside the longitudinal beam 202, with both ends extending outwards along the ends of the longitudinal beam 202. The two clamping heads 208 are threaded to both ends of the outer wall of the lead screw 206. The servo motor 207 is driven and connected to one end of the lead screw 206 and fixed to the longitudinal beam 202, enabling the servo motor 207 to drive the lead screw 206 to rotate. The servo motor 207 can be reinforced with a motor frame to maintain a relatively fixed position with the longitudinal beam 202 or the crossbeam 201, providing stable support for the servo motor 207. This allows the servo motor 207 to drive the lead screw 206 to rotate stably after power is applied. The threads on the outer wall of the lead screw 206 at the end position are opposite in direction, so that when the lead screw 206 rotates, it can drive the two clamping heads 208 on the same longitudinal beam 202 to move synchronously towards each other. Since the clamping heads 208 and the positioned hopper ear tube 101 are at the same horizontal height, the ends of the clamping heads 208 can be inserted into the recessed slots on the end face of the hopper ear tube 101 during the movement. In this way, the two clamping heads 208 are inserted into the slots at both ends of the same hopper ear tube 101, thus achieving clamping of the hopper ear tube 101. At the same time, the hopper ear tube 101 and the hopper body 100 are welded or integrally formed, so that the clamping heads 208 can clamp and fix the hopper body 100 in the position within the U-shaped frame, ensuring the stability of the hopper body 100 during lifting and transportation.

[0029] It should be noted that the clamping head 208 includes a connecting nut seat 281 that is threaded into the outer wall of the lead screw 206, a connecting rod 282 that is parallel to the upper part of the left and right limit blocks 203 and fixed to the outer wall of the connecting nut seat 281, and a conical plug 283 that is fixedly connected to the end of the connecting rod 282 away from the connecting nut seat 281. The end of the connecting nut seat 281 has a threaded hole that matches the lead screw 206, while the connecting rod 282 is used to connect and fix the conical plug 283 and the connecting nut seat 281. At the same time, it makes a distance difference between the conical plug 283 and the connecting nut seat 281, which can better meet the clamping work of inserting the conical plug 283 into the hole groove at the end of the hopper ear tube 101.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
