Description

Technical Field

[0001] This utility model relates to the field of batching scale technology, specifically to an anti-clogging mechanism for a large-capacity batching scale. Background Technology

[0002] A batching scale is a weighing instrument typically used to measure the proportions of several substances in a given batch. It has a wide range of applications, suitable for both batching multiple materials and measuring a single material (hopper scale). A batching scale usually consists of a weighing system, a batching system, a control system, and a data processing system. Through high-precision weighing and measurement, and intelligent control of the control and data processing systems, it can achieve automated batching, improve production efficiency, reduce costs, and minimize the impact of human factors on the batching process, thus improving batching accuracy and product quality stability. In the feed processing industry, batching scales are often used in conjunction with equipment such as sewing conveyors to achieve automated batching and quantitative packaging of feed ingredients.

[0003] Traditional batching scales are limited by the size of the feeding pipe and valve. Material falling from the hopper can easily get stuck in the feeding pipe and valve. When the feeding pipe and valve are blocked, the material in the hopper cannot fall normally, which reduces the efficiency of material falling from the hopper and ultimately reduces the batching efficiency of the batching scale.

[0004] Therefore, we propose an anti-clogging mechanism for large-capacity batching scales. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging mechanism for a large-capacity batching scale to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-capacity batching scale anti-clogging mechanism, comprising a hopper, a discharge pipe at the bottom of the hopper, a fixed frame fixedly installed in the middle of the discharge pipe, a drive motor fixedly installed on the front of the fixed frame, and support crossbeams located on the front and rear sides of the discharge pipe fixedly installed at the bottom of the fixed frame. A rotating rod is rotatably connected to one end of the fixed frame, and one end of the rotating rod is fixedly installed to the output end of the drive motor. A rotating shaft is rotatably connected to the middle of the support crossbeams, and one end of the rotating shaft is drively connected to the rotating rod. The other end is fixedly installed with a rotating sleeve located inside the supporting crossarm. The outer circumference of the rotating sleeve is fixedly installed with an arc-shaped toothed plate located inside the supporting crossarm. Displacement grooves are opened on the upper and lower sides inside the supporting crossarm. Sliding grooves are opened at both ends of the two opposing surfaces of the supporting crossarms. A transmission rod is slidably connected to the displacement groove. A rack is fixedly installed on the surface of the transmission rod. A spring is fixedly connected to one end of the transmission rod. A sliding crossbar that is slidably connected to the sliding groove is integrally connected to the other end of the transmission rod. The rack meshes with the arc-shaped toothed plate. An impact hammer is fixedly installed on the side of the sliding crossbar near the feed pipe.

[0007] Optionally, the other end of the spring is fixedly installed inside the supporting crossarm.

[0008] Optionally, two arc-shaped toothed plates are symmetrically arranged on the outer circumference of the same rotating sleeve, and the central axis of the two arc-shaped toothed plates coincides with the central axis of the rotating sleeve.

[0009] Optionally, the two arc-shaped toothed plates mesh with two racks, and the two racks are fixedly installed on the opposite sides of the two transmission rods. The two transmission rods are symmetrically arranged with the center of the rotating sleeve as the center of symmetry, and the angle formed between the two ends of the arc-shaped toothed plates and the center of the arc-shaped toothed plates is ninety degrees.

[0010] Optionally, sprockets are fixedly installed at both ends of the rotating rod, and another sprocket located outside the supporting crossarm is fixedly installed on the rotating shaft. The two sprockets are connected by chain drive.

[0011] Optionally, the two sliding crossbars are symmetrically arranged on both sides of the feed tube, and a connecting rod is fixedly installed on the opposite side of the sliding crossbars. The impact hammer is fixedly installed at the end of the connecting rod.

[0012] Optionally, the connecting rods have different lengths, and the impact hammers are evenly distributed with the center of the lower material tube as the center.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This large-capacity batching scale's anti-clogging mechanism uses a rotating sleeve and an arc-shaped toothed plate. A drive motor rotates a rotating rod, which in turn rotates a rotating shaft and the rotating sleeve. The rotation of the rotating sleeve causes the arc-shaped toothed plate to rotate. When the arc-shaped toothed plate meshes with the rack, the rack moves with the rotation of the arc-shaped toothed plate, thus moving the sliding crossbar away from the feed pipe. When the arc-shaped toothed plate deflects to a certain angle, it no longer meshes with the rack. Under the action of the spring, the transmission rod moves rapidly in the opposite direction, causing the impact hammer on the sliding crossbar to strike the outer wall of the feed pipe, causing the feed pipe to vibrate. At this time, the material falling through the feed pipe is affected by the vibration and is less likely to clog in the pipe and valve, thus ensuring good material falling efficiency and ultimately ensuring the batching efficiency of the batching scale.

[0019] 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.

[0020] Please see Figures 1 to 3This utility model provides an anti-clogging mechanism for a large-capacity batching scale, including a hopper 1, a discharge pipe 2 at the bottom of the hopper 1, a fixed frame 3 fixedly installed in the middle of the discharge pipe 2, a drive motor 4 fixedly installed on the front of the fixed frame 3, and support crossbeams 5 located on the front and rear sides of the discharge pipe 2 fixedly installed at the bottom of the fixed frame 3. A rotating rod 6 is rotatably connected to one end of the fixed frame 3, and one end of the rotating rod 6 is fixedly installed to the output end of the drive motor 4. A rotating shaft 7 is rotatably connected to the middle of the support crossbeams 5, and one end of the rotating shaft 7... The rotating shaft 7 is connected to the rotating rod 6. A rotating sleeve 8 is fixedly installed inside the supporting crossarm 5 at the other end. An arc-shaped toothed plate 9 is fixedly installed inside the supporting crossarm 5 on the outer circumferential surface of the rotating sleeve 8. Displacement grooves 10 are provided on the upper and lower sides inside the supporting crossarm 5. Sliding grooves 13 are provided at both ends of the opposite surfaces of the two supporting crossarms 5. A transmission rod 11 is slidably connected to the displacement grooves 10. A rack 12 is fixedly installed on the surface of the transmission rod 11. A spring 17 is fixedly connected to one end of the transmission rod 11. The other end of the transmission rod 11... A sliding crossbar 14 is integrally connected to the sliding groove 13. A rack 12 meshes with an arc-shaped toothed plate 9. An impact hammer 16 is fixedly installed on the side of the sliding crossbar 14 near the feed pipe 2. By setting a rotating sleeve 8 and an arc-shaped toothed plate 9, the drive motor 4 drives the rotating rod 6 to rotate, which in turn drives the rotating shaft 7 and the rotating sleeve 8 to rotate. The rotation of the rotating sleeve 8 drives the arc-shaped toothed plate 9 to rotate. When the arc-shaped toothed plate 9 meshes with the rack 12, the rack 12 moves with the rotation of the arc-shaped toothed plate 9, thereby driving the sliding crossbar 14 to rotate. When rod 14 moves away from feed pipe 2, and the arc-shaped toothed plate 9 deflects to a certain angle, the arc-shaped toothed plate 9 and the rack 12 no longer mesh. Under the action of spring 17, the transmission rod 11 moves quickly in the opposite direction, causing the impact hammer 16 on the sliding crossbar 14 to strike the outer wall of feed pipe 2 quickly, causing feed pipe 2 to vibrate. At this time, the material falling through feed pipe 2 is affected by the vibration and is less likely to block in the pipe and valve, thus ensuring that the material maintains good falling efficiency, and ultimately ensuring the batching efficiency of the batching scale.

[0021] The other end of the spring 17 is fixedly installed inside the support crossarm 5.

[0022] Two arc-shaped toothed plates 9 are symmetrically arranged on the outer circumference of the same rotating sleeve 8, and the central axis of the two arc-shaped toothed plates 9 coincides with the central axis of the rotating sleeve 8.

[0023] Two arc-shaped toothed plates 9 mesh with two racks 12 respectively. The two racks 12 are fixedly installed on the opposite sides of two transmission rods 11. The two transmission rods 11 are symmetrically arranged with the center of the rotating sleeve 8 as the center of symmetry. The angle formed between the two ends of the arc-shaped toothed plates 9 and the center of the arc-shaped toothed plates 9 is ninety degrees.

[0024] Sprockets 18 are fixedly installed at both ends of the rotating rod 6, and another sprocket 18 located outside the supporting crossarm 5 is fixedly installed on the rotating shaft 7. The two sprockets 18 are connected by a chain 19.

[0025] Two sliding crossbars 14 are symmetrically arranged on both sides of the feed tube 2. A connecting rod 15 is fixedly installed on the opposite side of the sliding crossbars 14. The impact hammer 16 is fixedly installed at the end of the connecting rod 15.

[0026] The connecting rods 15 have different lengths, and the impact hammers 16 and the material tubes 2 are evenly arranged with the center of the circle as the center.

[0027] Working principle:

[0028] The drive motor 4 drives the rotating rod 6 to rotate, which in turn drives the rotating shaft 7 and the rotating sleeve 8 to rotate. The rotation of the rotating sleeve 8 drives the arc-shaped toothed plate 9 to rotate. When the arc-shaped toothed plate 9 meshes with the rack 12, the rack 12 moves with the rotation of the arc-shaped toothed plate 9, thereby driving the sliding crossbar 14 away from the feed pipe 2. When the arc-shaped toothed plate 9 deflects to a certain angle, the arc-shaped toothed plate 9 and the rack 12 no longer mesh. The transmission rod 11 moves quickly in the opposite direction under the action of the spring 17, causing the impact hammer 16 on the sliding crossbar 14 to quickly hit the outer wall of the feed pipe 2, causing the feed pipe 2 to vibrate. At this time, the material falling through the feed pipe 2 is affected by the vibration and is less likely to block in the pipe and valve, thus ensuring that the material maintains good falling efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
