Description

Technical Field

[0001] This utility model relates to the field of belt straightening technology, and in particular to a device for correcting belt misalignment in rice conveyors. Background Technology

[0002] In the rice production and processing process, belt conveyors are key equipment for achieving continuous rice transportation. They are widely used in material transfer in processes such as cleaning, hulling, milling, and packaging. However, belt misalignment is a common equipment failure during rice transportation. Existing technology uses self-aligning idlers to correct the misaligned belt. They mainly generate lateral corrective force by deflecting the idler bracket, pushing the belt back to the center position, which alleviates the misalignment problem to a certain extent.

[0003] During rice conveying, impurities such as broken rice, rice husks, and dust easily adhere to the surface of the belt. These impurities gradually accumulate on the surface of the self-aligning idler as the belt rotates. The accumulated impurities change the friction coefficient between the idler and the belt, causing an imbalance in the lateral corrective force of the idler on the belt, which affects the normal corrective function of the idler. To address this problem, we propose a rice conveyor belt deviation correction device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for correcting belt misalignment in rice conveyors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rice conveyor belt misalignment correction device includes a support plate, a connecting frame rotatably connected to the top of the support plate, an idler roller installed above the connecting frame, a connecting ring fixedly sleeved at the bottom of the connecting frame, a connecting rod fixedly connected to the side of the connecting ring, a connecting strip at the top of the connecting rod, and brushes evenly distributed on the inner side of the connecting strip.

[0007] Preferably, there are two sets of connecting rods and connecting strips, and the two sets of connecting rods and connecting strips are symmetrically distributed about the central axis of the support plate.

[0008] Preferably, the bottom end of the connecting strip is fixedly connected to a connecting sleeve, and the connecting sleeve is movably sleeved on the top end of the connecting rod. A fixing block is fixedly sleeved on the outer side of the connecting rod, and a connecting groove is opened inside the fixing block. The inner wall of the connecting groove is connected to the connecting plate through a connecting spring, and a limit block is fixedly connected to the inner side of the connecting plate. The top ends of the connecting sleeve and the connecting rod are provided with limit grooves that are adapted to the limit block.

[0009] Preferably, a pinch block is fixedly connected to the side of the connecting plate, and the pinch block is configured as a semi-circular structure.

[0010] Preferably, the connecting plate has a slot inside, and a guide rod is inserted into the slot, with the end of the guide rod fixedly connected to the inner wall of the connecting slot.

[0011] Preferably, the outer surface of the limiting block is bonded with a rubber sleeve, and the outer surface of the rubber sleeve abuts against the inner wall of the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device is equipped with connecting strips and brushes. During use, the connecting strips and brushes work together to clean the debris attached to the outer surface of each set of idlers, thereby maintaining a uniform coefficient of friction between the idlers and the belt and avoiding imbalance of the corrective force caused by the accumulation of local impurities.

[0014] 2. The device is equipped with a fixing block and a limiting block.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A rice conveyor belt misalignment correction device includes a support plate 1, a connecting frame 2 rotatably connected to the top of the support plate 1, and an idler roller 3 installed above the connecting frame 2. The support plate 1 and the connecting frame 2 are connected by a connector, which can meet the deflection requirements of the connecting frame 2 and the idler roller 3, thereby correcting the belt misalignment by generating a lateral force through tilting. The specific correction principle is existing technology and will not be described in detail here. A connecting ring 4 is fixedly sleeved at the bottom of the connecting frame 2, and a connecting rod 5 is fixedly connected to the side of the connecting ring 4. A connecting strip 6 is provided at the top of the connecting rod 5, and brushes 7 are evenly distributed on the inner side of the connecting strip 6. The brushes 7 can be made of nylon material, which has good flexibility and will not scratch the surface of the idler roller 3 when in contact with it. At the same time, it can effectively remove broken rice and dust from the surface and avoid secondary pollution.

[0022] Furthermore, refer to Figure 1 and Figure 2 It can be seen that there are two sets of connecting rods 5 and connecting strips 6, and the two sets of connecting rods 5 and connecting strips 6 are symmetrically distributed about the central axis of the support plate 1. During use, the two sets of connecting rods 5 can support the two sets of connecting strips 6. Since there are two sets of connecting strips 6, there are also two sets of brushes 7, which can effectively improve the cleaning effect on the outer surface of the roller 3.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the bottom end of the connecting strip 6 is fixedly connected to the connecting sleeve 8, and the connecting sleeve 8 is movably sleeved on the top end of the connecting rod 5. The outer side of the connecting rod 5 is fixedly sleeved with the fixing block 9, and the inside of the fixing block 9 is provided with the connecting groove 10. The inner wall of the connecting groove 10 is connected to the connecting plate 12 through the connecting spring 11, and the inner side of the connecting plate 12 is fixedly connected with the limiting block 13. The top end of the connecting sleeve 8 and the connecting rod 5 is provided with the limiting groove that matches the limiting block 13. During use, through the mutual cooperation of the connecting sleeve 8 and the limiting groove, when the staff inspects this device, they only need to pull the connecting plate 12 horizontally to pull the limiting block 13 out of the limiting groove inside the connecting rod 5 and the connecting sleeve 8. Then the staff can pull the connecting strip 6 up to pull the connecting sleeve 8 out from the top end of the connecting rod 5. At this time, the quick disassembly of the connecting strip 6 and the brush 7 can be completed.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a pinch block 15 is fixedly connected to the side of the connecting plate 12, and the pinch block 15 is set as a semi-circular structure. The pinch block 15 with a semi-circular structure can facilitate the staff to quickly pull the connecting plate 12, so as to effectively improve the convenience of using this device.

[0025] Furthermore, refer to Figure 3 and Figure 4It can be seen that the connecting plate 12 has a slot inside, and a guide rod 14 is inserted inside the slot. The end of the guide rod 14 is fixedly connected to the inner wall of the connecting groove 10. During use, the vertical positioning of the connecting plate 12 can be achieved through the cooperation of the slot and the guide rod 14, so as to ensure the tightness of the limiting block 13 being inserted into the limiting groove.

[0026] Furthermore, refer to Figure 3 It can be seen that the outer surface of the limiting block 13 is glued with a rubber sleeve, and the outer surface of the rubber sleeve abuts against the inner wall of the limiting groove. The rubber sleeve is not shown in the figure. By setting the rubber sleeve, the limiting block 13 can be interference-fitted with the limiting groove, which can further ensure the reliability of the limiting block 13 being inserted into the limiting groove.

[0027] Working principle: When using this utility model, the operator can first install each set of support plates 1 at a suitable position on the conveyor frame, and then the belt can be wound and installed on the outer surface of the idler roller 3. Then, by starting the conveyor, the rice can be conveyed. During the conveying process, the support plates 1, the connecting frame 2 and the idler roller 3 can be used to correct the belt deviation in time.

[0028] When the device is running, each set of idler rollers 3 is in a rotating state and will come into contact with the brush 7 set on the inner side of the connecting strip 6, thereby realizing the rapid scraping of the debris attached to the outer surface of the idler rollers 3, ensuring the normal contact between the idler rollers 3 and the belt and performing the correction work, thus ensuring the safety of the device during use. The above is the complete working principle of this utility model.
