Description

Technical Field

[0001] This utility model belongs to the technical field of material conveying equipment, and in particular relates to a chain-type anti-deviation feeder. Background Technology

[0002] A feeder is a type of material conveying equipment currently in use. It is an industrial machine used to uniformly and continuously transport materials from a storage bin or storage equipment to a receiving device. It mainly consists of four parts: a hopper, a conveyor belt, a motor, and a frame.

[0003] Chinese patent application CN210084231U discloses an anti-deviation chain feeder, including a mounting plate. A motor is horizontally mounted at the bottom of the mounting plate, and two first rotating shafts are horizontally mounted at both ends of the top of the mounting plate. The output shaft of the motor drives the first rotating shafts via a transmission belt. Gears are mounted on the shafts of the first rotating shafts, and a chain conveyor belt meshes with the gears. The chain conveyor belt has multiple grooves on its outer side, and toothed blocks mesh within the grooves. The toothed blocks are mounted on the bottom surface of the conveyor belt via a snap-fit ​​structure. A connecting plate is mounted on the upper center of the mounting plate, and a threaded rod is horizontally screwed to the top of the connecting plate through a screw hole. The end of the threaded rod near the conveyor belt is horizontally inserted into one end of a U-shaped mounting ear through an opening. Guide wheels rotate on both sides of the conveyor belt to prevent deviation. Springs ensure a tighter fit between the guide wheels and the conveyor belt, and anti-slip sleeves prevent the guide wheels from slipping.

[0004] The aforementioned anti-deviation chain feeder primarily uses connecting plates installed on both sides of the conveyor belt. These connecting plates are equipped with handwheels and threaded rods. The ends of the threaded rods abut against the outer wall of the conveyor belt via guide wheels. This anti-deviation structure is manual. When the conveyor belt operates at high speed, material on it will inevitably spill outwards. Manual operation can cause operators to inhale material dust particles, posing a safety hazard. Furthermore, this belt feeder has a short center distance and uses a soft leather conveyor belt for material transport. Although a chain conveyor belt is added at the bottom to drive the leather conveyor belt, the uneven stress on the leather belt causes deviation, resulting in unstable material transport when the chain conveyor belt is driven. Therefore, we provide a chain-type anti-deviation feeder to solve the aforementioned problems. Utility Model Content

The tensioning assembly includes a slider connected to the mounting bracket 1, and a hydraulic push rod is also mounted on the side wall of the slider.

[0007] The present invention is further configured such that a bucket mounting plate is installed on the upper side wall of the hopper, and the hopper is connected to the bucket through the bucket mounting plate; a sliding groove is provided on the side of the bucket and on the inner wall of the hopper.

[0008] The present invention is further configured such that the sliding push plate is disposed in the first sliding groove, and both the sliding push plate and the end plate are slidably connected to the first sliding groove. There are multiple sliding push plates, and the bottom of each sliding push plate is provided with a plate groove, that is, the sliding push plate is arranged in an L shape.

[0011] The present invention is further configured such that the transmission cylinder is located at the middle and rear part of the rotating rod, the small grooved wheel is installed at the front end of the rotating rod, and the large grooved wheel is installed on the output shaft of the drive motor.

[0012] The present invention is further configured such that a second sliding groove is provided on the upper side wall of the base, the hydraulic push rod is disposed in the second sliding groove, and a connecting sleeve and a fixing seat are respectively installed at both ends of the hydraulic push rod.

[0013] The present invention is further configured such that the hydraulic push rod is connected to the slider through a connecting sleeve, and the hydraulic push rod is connected to the outer end of the slide groove two through a fixed seat. The slider is also fixedly installed on the bottom side wall of the mounting frame one, and the mounting frame one is slidably connected to the slide groove two through the slider.

[0014] This utility model has the following beneficial effects: This utility model features an opening and closing assembly located on the top of the material box. This assembly controls whether the top of the material box opens and closes. The top of the material box has a hopper mounting plate for hopper installation, and the opening and closing assembly is located beside the hopper mounting plate. A sliding groove is formed on the inner wall of the top of the material box where the opening and closing assembly is located. The opening and closing assembly includes multiple sliding push plates slidably disposed within the sliding groove, and end plates disposed at the ends of the sliding push plates. Electric push rods are provided between adjacent sliding push plates and between the sliding push plates and the end plates. The bottom sidewall of each sliding push plate... Each slide plate is provided with a groove. The upper slide plate slides and engages with the lower slide plate through the groove on its bottom side wall. At the same time, the front and rear sides of the slide plate are also slidably connected to the inner wall of the slide groove. Electric push rods are installed at the front and rear ends of the groove. That is, the upper slide plate is also connected to the lower slide plate through the electric push rod. When the electric push rod extends, it can push the multi-stage slide plates and end plates outward, thereby causing the slide plates and end plates to slide and extend to the top of the material box, thus achieving the effect of sealing the material box. Conversely, the upper port of the material box gradually opens.

[0015] This invention comprises a drive assembly, a transmission assembly, and a tensioning assembly. The drive assembly is connected to the conveyor belt via the transmission assembly, providing power to the conveyor belt through the power transmission of the transmission assembly. A tensioning assembly is located at the bottom of the drive assembly, adjusting the distance between the drive assembly and the transmission assembly to improve the stability of power transmission. The drive assembly includes a base positioned beside the conveyor belt, with a second sliding groove on the upper side wall of the base. A mounting bracket is located above the base, and the drive motor is mounted on the mounting bracket. Inside the first mounting bracket, the transmission assembly includes a second mounting bracket located beside the drive motor. A rotating rod is rotatably mounted within the second mounting bracket. A transmission cylinder, meshing with the conveyor chain, is mounted on the rear middle portion of the rotating rod, and a small grooved wheel is mounted on the front end. The small grooved wheel is connected to a large grooved wheel via a linkage belt, and the large grooved wheel is mounted on the output shaft of the drive motor. The tensioning assembly includes a slider slidably disposed within a second slide groove in the base. The slider is fixedly mounted on the bottom side wall of the first mounting bracket. Thus, the first mounting bracket is slidably connected to the second slide groove via the slider, and the side wall of the slider is connected to a hydraulic push rod via a connecting sleeve. The other end of the hydraulic push rod is connected to the base via a fixed seat. During operation, the drive motor first operates, causing the large grooved wheel on its output shaft to rotate. Then, under the traction of the linkage belt, the small grooved wheel also rotates, carrying the rotating rod. Since the transmission cylinder on the rotating rod meshes with the conveyor chain, the conveyor chain is driven to move. Simultaneously, the conveyor chain also receives material flowing from the guide pipe, thus realizing the material transport on the conveyor chain. However, after prolonged operation, the linkage belt on the transmission assembly may become somewhat loose, leading to a loosening between the large and small grooved wheels. Unstable power transmission can cause vibrations in the conveyor belt, leading to material deviation and unstable conveying speed. In this situation, the hydraulic push rod in the tensioning assembly extends, pushing the slider to move within the second slide groove. The slider is fixed to the bottom of the first mounting frame, and the drive motor is installed inside the first mounting frame. This allows the drive motor to move on the second slide groove, increasing the distance between the drive motor and the rotating rod, thus ensuring the belt remains taut and guaranteeing the stability of power transmission.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0025] Please see Figure 1-2 This utility model is a chain-type anti-deviation feeder, including a material box 1, a hopper 2 and a conveyor chain 5. The material is fed into the material box 1 through the hopper 2 and flows onto the conveyor chain 5 through the guide pipe 4. The conveyor chain 5 has sulfide metal strips inside the belt, which are connected to the chain structure to increase the belt strength.

[0026] Specifically, a hopper 2 is provided at the upper end of the material box 1, and an opening and closing component 3 is provided on the side of the hopper 2. A guide pipe 4 is provided below the hopper 2, and a conveyor belt 5 is provided below the guide pipe 4.

[0027] Furthermore, the upper end of the guide pipe 4 is connected to the output port at the bottom of the hopper 2, thereby realizing the receiving and transfer of materials. The guide pipe 4 is in an inclined state, which ensures the stability of the material falling process. Below the conveyor belt 5, there is an equipment frame 6. Multiple support rollers 501 are installed at equal intervals on the equipment frame 6. The support rollers 501 are also connected to the conveyor belt 5 to support the conveyor belt 5 and ensure the smooth movement of the conveyor belt 5. Example 2

[0028] Please see Figure 3-4 Based on embodiment 1, an opening and closing component 3 is also provided. The opening and closing component 3 consists of multiple sliding push plates 301 that slide and cooperate with each other. An electric push rod 302 is also provided between the sliding push plates 301 to provide power support for their sliding, thereby realizing the sealing or opening operation of the upper port of the material box 1. The size of the sealing area can also be controlled.

[0029] Specifically, a bucket mounting plate 102 is installed on one side of the upper end slot of the material box 1. The bucket mounting plate 102 is used for the installation of the bucket 2. A sliding groove 101 is provided on the side of the bucket mounting plate 102 and on the inner wall of the upper end slot of the material box 1. The opening and closing component 3 is installed inside the sliding groove 101.

[0030] Furthermore, the opening and closing assembly 3 includes multiple sliding push plates 301, each with a plate groove 301a at its bottom, i.e., the sliding push plate 301 is L-shaped. The upper-level sliding push plate 301 is slidably connected to the outer wall of the lower-level sliding push plate 301 through the plate groove 301a on its bottom side wall. Electric push rods 302 are installed at both ends of the trough 301a. The upper-level sliding push plate 301 is connected to the lower-level sliding push plate 301 through the electric push rods 302. The electric push rods 302 provide power support for the sliding and retraction of the lower-level sliding push plate 301. The outermost sliding push plate 301 is also connected to the end plate 303 through the electric push rods 302. That is, it provides power support for the sliding and retraction of the end plate 303. The outer end of the end plate 303 is connected to the bucket mounting plate 102.

[0031] The operation process of this embodiment is as follows: when the electric push rod 302 extends, it can push the multi-stage sliding push plate 301 and the end plate 303 outward, thereby causing the sliding push plate 301 and the end plate 303 to slide and extend on the top of the material box 1 until the outermost end plate 303 is connected with the bucket mounting plate 102 and then the extension action of the electric push rod 302 stops, thereby achieving the effect of sealing the material box 1. Conversely, the upper port of the material box 1 will gradually open. Example 3

[0032] Please see Figure 5-6Based on Embodiments 1 and 2, a drive assembly 7, a transmission assembly 8, and a tensioning assembly 9 are also provided. The drive assembly 7 is mainly a drive motor 703. The transmission assembly 8 is mainly a large grooved wheel 805, a small grooved wheel 803, and a linkage belt 804 for connecting the two. The drive motor 703 can provide power support to the large grooved wheel 805, and then, under the linkage effect of the linkage belt 804 and the small grooved wheel 803, it provides rotational power support to the transmission cylinder 802 that meshes with the conveyor chain belt 5. The tensioning assembly 9 is mainly a hydraulic push rod 901. The position of the drive motor 703 can be adjusted by the hydraulic push rod 901, thereby ensuring that the linkage belt 804 is always in a taut state.

[0033] Specifically, the drive assembly 7 is located on the side of the conveyor belt 5. The drive assembly 7 includes a base 701 fixed on the bottom side wall of the hopper 1, and a mounting bracket 702 is also provided above the right end of the base 701. The drive motor 703 is installed inside the mounting bracket 702. A transmission component 8 is provided on the side of the drive component 7. The transmission component 8 includes a mounting bracket 806 fixed above the left end of the base 701. A rotating rod 801 is rotatably mounted inside the mounting bracket 806. A transmission cylinder 802 that meshes with the conveyor chain belt 5 is installed at the middle and rear part of the rotating rod 801. A small grooved wheel 803 is installed at the front end. The small grooved wheel 803 is connected to a large grooved wheel 805 through a linkage belt 804. The large grooved wheel 805 is mounted on the output shaft of the drive motor 703, thereby achieving the power transmission effect.

[0034] Furthermore, the upper side wall of the base 701 is provided with a second sliding groove 701a. The tensioning assembly 9 includes a slider 904 that is slidably disposed in the second sliding groove 701a of the base 701. The slider 904 is fixedly installed on the bottom side wall of the mounting bracket 702. That is, the mounting bracket 702 is slidably connected to the second sliding groove 701a through the slider 904. The side wall of the slider 904 is connected to the hydraulic push rod 901 through the connecting sleeve 902. The other end of the hydraulic push rod 901 is connected to the base 701 through the fixed seat 903.

[0035] The operation process of this embodiment is as follows: In use, the drive motor 703 first works, and the large grooved wheel 805 on its output shaft also rotates. Then, under the traction of the linkage belt 804, the small grooved wheel 803 also rotates the rotating rod 801. Since the transmission cylinder 802 on the rotating rod 801 is engaged with the conveyor chain belt 5, the conveyor chain belt 5 is driven to move. At the same time, the conveyor chain belt 5 is also used to receive the material flowing out from the guide pipe 4, thus realizing the transportation of materials on the conveyor chain belt 5. However, after the transmission component 8 has been working for a long time, the linkage belt 804 on it will become somewhat loose, which will cause the power transmission between the large grooved wheel 805 and the small grooved wheel 803 to be unstable. This can cause the conveyor belt 5 to vibrate when transporting materials, leading to material deviation and unstable material conveying speed. In this state, the hydraulic push rod 901 in the tensioning component 9 works, extending to push the slider 904 to move within the slide groove 701a. The slider 904 is fixed to the bottom of the mounting frame 702, and the drive motor 703 is installed inside the mounting frame 702. This achieves the effect of pushing the drive motor 703 to move on the slide groove 701a, which increases the distance between the drive motor 703 and the rotating rod 801, thus ensuring that the linkage belt 804 is always taut and ensuring the stability of power transmission.
