Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural product transportation, in particular to a conveying belt deviation correcting device for preventing conveying belt deviation. BACKGROUND

[0002] The conveying belt, also known as a belt conveyor, is suitable for continuous transportation of blocky and powdery materials. Compared with other transportation equipment, the belt conveyor has the advantages of long conveying distance, large transportation capacity, continuous conveying, reliable operation, and easy automation and centralized control. Belt deviation is a common problem of flexible conveying belt equipment. When the conveying belt has accumulated goods, uneven weight, quality defects, roadway deformation, installation deviation, etc., belt deviation often occurs, which increases the running resistance of the belt and accelerates the wear of the belt. In severe cases, it may also cause material spilling along the machine, edge scraping, edge tearing, etc., affecting the working efficiency of the conveying belt and the quality of the food. Chinese Patent No. CN118753712B discloses a deviation correcting device for a belt conveyor. In this patent, a deviation correcting mechanism is arranged on the transmission track of the conveying belt. When the conveying belt deviates at a certain position, the corresponding straightening plate will be pushed by the conveying belt. When the straightening plate moves into the lower moving section, the internal thread will come into contact with the external thread, thereby providing the driving block with the power for deviation correction, which can move the deviated position of the conveying belt to the initial setting direction, thereby achieving the effect of deviation correction.

[0003] The existing conveying belt deviation correcting device for preventing conveying belt deviation has the problem of not being able to timely correct the conveying belt deviation, which causes the conveying belt to be damaged or scrapped, reduces the service life of the belt conveyor, and the impact of agricultural products on the conveying belt and uneven distribution of agricultural products during conveying can exacerbate the wear and deviation of the conveying belt.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] First embodiment: as follows Figures 1-5 As shown, the present invention provides a technical solution: a conveyor belt correction device for preventing conveyor belt skewing, comprising a support base 1, a drive mechanism 3, and a detection and protection mechanism 7. A connecting plate 2 is fixedly connected to the surface of the support base 1, a plastic plate 9 is fixedly connected to the middle position of the surface of the connecting plate 2, and a pressing wheel device 8 is fixedly connected to the lower position of the surface of the connecting plate 2. The drive mechanism 3 is fixedly installed on the surface of the connecting plate 2, and a friction belt 4 is sleeved on the surface of the drive mechanism 3. A rubber side belt 6 is fixedly connected to the surface of the friction belt 4 near the edge, and a partition plate 5 is fixedly connected to the surface of the friction belt 4 near the middle. The drive mechanism 3 is used for reciprocating drive of the friction belt 4 and correction when the friction belt 4 is skewed.

[0038] The detection and protection mechanism 7 is fixedly installed in the middle of the surface of the connecting plate 2. The detection and protection mechanism 7 is used to detect the deviation of the friction belt 4 and to press and prevent agricultural products on the surface of the friction belt 4 from falling off.

[0039] The drive mechanism 3 includes a first motor 34, which is fixedly mounted on the surface of the connecting plate 2. A connecting rod 35 is fixedly connected to the output end of the first motor 34. A roller body 36 is fixedly connected to the end face of the connecting rod 35. A rectangular through hole 361 is opened in the middle of the surface of the roller body 36. A fixing strip 37 is fixedly connected to the inner side of the roller body 36. A telescopic cylinder 38 is fixedly connected to the surface of the fixing strip 37. A sliding strip 39 is fixedly connected to the output end of the telescopic cylinder 38.

[0040] The driving mechanism 3 further comprises a protective shell 31 fixedly installed on the surface of the connecting plate 2 close to the first motor 34, and the surface of the protective shell 31 is fixedly connected with a hydraulic cylinder 32, and the output end of the hydraulic cylinder 32 is fixedly connected with a sliding push plate 33.

[0041] In use, the friction belt 4 is used to convey agricultural products from a low place to a high place, and the pressure covering wheel device 8 comprises a shell and a pressure covering roller, and the roller body 36 rotates under the driving of the first motor 34. Since the surface of the friction belt 4 has tension, the friction belt 4 is driven to rotate by the roller body 36, and the pressure covering roller guides the turning position of the friction belt 4. The agricultural products are lifted in batches by the partition plate 5, and the rubber side belt 6 limits the agricultural products. The detection protection mechanism 7 is arranged above the friction belt 4 close to the climbing section, and the detection protection mechanism 7 detects the distance of the edge position of the climbing section of the friction belt 4, so as to judge the degree of deflection of the friction belt 4. When the deflection of the friction belt 4 exceeds a certain threshold value, the hydraulic cylinder 32 drives the sliding push plate 33 to move along the axis of the roller body 36, and the sliding push plate 33 pushes and corrects the up and down straight sections of the friction belt 4, solving the problem that the conveying belt cannot be corrected in time, causing the conveying belt to be damaged or scrapped, and reducing the service life of the belt conveyor.

[0042] Second embodiment: as shown in Figure 3 、 Figure 4 、 Figure 5 The friction belt 4 is sleeved on the outer surface of the roller body 36, the inner side surface of the sliding push plate 33 is slidably connected with the surface of the roller body 36 close to the end surface, the sliding push plate 33 is in a rectangular structure, the number of the sliding push plate 33 is four, the plastic plate 9 is a plate-shaped structure made of white plastic particles by injection molding, the friction belt 4 is a belt-shaped structure made of black rubber particles by calendering, the number of the rubber side belt 6 is two, the number of the partition plate 5 is multiple, the friction belt 4 is provided with a straight section and a climbing section, the sliding push plate 33 is arranged at the straight section of the friction belt 4, and a gap is formed between the edge of the friction belt 4 and the connecting plate 2.

[0043] In use, the output end of the distance detector 75 is electrically connected to the input ends of the first motor 34 and the telescopic cylinder 38. When the skewness of the friction belt 4 exceeds a certain threshold, the first motor 34 drives the connecting rod 35 to stop rotating, and the telescopic cylinder 38 controls the sliding bar 39 to slide into the rectangular through hole 361. The detection and protection mechanism 7 supports the agricultural products at the slope position, and the tension of the friction belt 4 decreases but does not cause the friction belt 4 to slip and flip. At this time, the hydraulic cylinder 32 drives the sliding push plate 33 to move closer to the friction belt 4. The straight sections of the friction belt 4 at the upper and lower positions are equipped with sliding push plates 33. The pushing of the sliding push plates 33 pushes the friction belt 4 to be straightened. Subsequently, the telescopic cylinder 38 controls the sliding bar 39 to reset. The arc position of the sliding bar 39 coincides with the surface of the roller body 36, and the friction belt 4 is tightly attached to the roller body 36. The tension of the friction belt 4 is restored, avoiding the inability to correct the skewness when the tension of the friction belt 4 is large. At the same time, it avoids serious wear on the friction belt 4 when the tension is large.

[0044] Third embodiment: as follows Figure 3 , Figure 6 , Figure 7 As shown, the detection and protection mechanism 7 includes a bent plate 71. The bottom end of the bent plate 71 is fixedly installed at the middle position of the surface of the connecting plate 2. The top end of the bent plate 71 is fixedly connected to a fixing plate 72. A second motor 73 is fixedly connected to the surface of the fixing plate 72 near the edge. The detection and protection mechanism 7 also includes a connecting roller 74. The end face of the connecting roller 74 is fixedly installed at the output end of the second motor 73. A gear 741 is fixedly connected to the outer surface of the connecting roller 74.

[0045] A flexible component 76 is fitted onto the surface of the gear 741. An actuating component 77 is fixedly connected to the inner side of the flexible component 76. An extension plate 78 is fixedly connected to the upper and lower positions on the surface of the fixed plate 72. A distance detector 75 is fixedly connected to the surface of the extension plate 78.

[0046] In use, the extension plate 78 fixes the distance detector 75 at the edge of the black friction belt 4. The distance detector 75 is used to detect the distance between the edge point of the black friction belt 4 and the connecting plate 2. There are two distance detectors 75, which are distributed at the beginning and end of the climbing section of the friction belt 4, respectively. They simultaneously detect the distance between the two points and the connecting plate 2. Then, the difference in the detected distance is used to determine the degree of skewness of the friction belt 4. The climbing section of the friction belt 4 is relatively long, making it easier and more accurate to determine the degree of skewness of the climbing section. The second motor 73 drives the connecting roller 74 to rotate. The connecting roller 74 and the gear 741 drive the flexible component 76 to rotate. When the friction belt 4 is not skewed, the second motor 73 drives the flexible component 76 to move with the friction belt 4. The second motor 73 is synchronized with the first motor 34. The agitator 77 moves the agricultural products to make them evenly distributed inside the partition 5, which solves the problem that the impact of agricultural products on the conveyor belt and the uneven distribution of agricultural products during the conveying process will aggravate the wear and skewness of the conveyor belt.

[0047] Fourth embodiment: as Figures 6-9 As shown, the flexible component 76 includes a chain 761, the surface of which meshes with the surface of a gear 741. An extension rod 762 is fixedly connected to the surface of the chain 761. The number of extension rods 762 is set to be multiple. The flexible component 76 also includes a rubber belt 763. The surface of the rubber belt 763 is fixedly installed on the end of the extension rod 762 away from the chain 761.

[0048] The actuating assembly 77 includes a third motor 771, which is fixedly installed at the center of the surface of the rubber frame 764. The output end of the third motor 771 is fixedly connected to a lead screw 772. The actuating assembly 77 also includes an internally threaded tube 773, the inner side of which is connected to the surface of the lead screw 772 via threads. A plastic plate 774 is fixedly connected to the surface of the internally threaded tube 773. A metal plate 775 is fixedly connected to the end face of the plastic plate 774. The metal plate 775 is fixedly installed at the corner of the inner side of the rubber frame 764. A rubber strip 776 is fixedly connected to the surface of the plastic plate 774.

[0049] In use, the white plastic plate 9 forms a color contrast with the black friction belt 4, and the strong color contrast makes the distance detector 75 more accurate. The meshing between the chain 761 and the gear 741 can effectively avoid the misalignment of the chain 761, and the connection roller 74 can drive the chain 761 to move more reliably. The rubber belt 763 rotates in the opposite direction of the friction belt 4, the rubber frame 764 is in contact with the partition plate 5 and the rubber edge belt 6, the agricultural products are in contact with the rubber strip 776, the third motor 771 drives the lead screw 772 to rotate, and under the characteristics of the screw thread lifting force, the inner threaded tube 773 reciprocates along the axis of the lead screw 772. The number of inner threaded tubes 773 is two, and the inner sides of the two inner threaded tubes 773 are in different spiral directions. The end surface position of the plastic plate 774 is fixed by the metal plate 775, so that the middle positions of the two plastic plates 774 are close to or away from each other. The rubber strip 776 can make the agricultural products evenly distributed between the partition plates 5, effectively reducing the uneven distribution of agricultural products leading to the deflection of the friction belt 4.

[0050] The fifth embodiment is shown in Figure 4 、 Figure 5 、 Figure 9 The first motor 34 is fixedly installed on the surface of the connecting plate 2, the output end of the first motor 34 is fixedly connected with the connecting rod 35, the end surface position of the connecting rod 35 is fixedly connected with the roller body 36, the rectangular through hole 361 is formed in the middle position of the surface of the roller body 36, the inner side of the roller body 36 is fixedly connected with the fixed strip 37, the surface of the fixed strip 37 is fixedly connected with the telescopic cylinder 38, the output end of the telescopic cylinder 38 is fixedly connected with the sliding strip 39, the protective shell 31 is fixedly installed on the surface of the connecting plate 2 close to the first motor 34, the surface of the protective shell 31 is fixedly connected with the hydraulic cylinder 32, and the output end of the hydraulic cylinder 32 is fixedly connected with the sliding push plate 33.

[0051] The third motor 771 is fixedly installed on the middle position of the surface of the rubber frame 764, the output end of the third motor 771 is fixedly connected with the lead screw 772, and the dolly assembly 77 further includes the inner threaded tube 773.

[0052] In use, the rubber frame 764 is made of rubber material, and gaps are formed between the plurality of rubber frames 764. When the gear 741 drives the chain 761 to rotate in the opposite direction of the friction belt 4, the rubber frame 764 is embedded between the baffle 5 and the rubber edge belt 6, the agricultural products inside the baffle 5 are in contact with the rubber strip 776, and the rubber frame 764 bears the downward gravity of the agricultural products when the agricultural products climb the slope. The distance detector 75 detects the difference in the distance from the edge of the friction belt 4, and when the degree of deflection of the friction belt 4 is too large, the second motor 73 stops driving the connecting roller 74 to rotate, at the same time, the friction belt 4 also stops rotating, the telescopic cylinder 38 controls the sliding strip 39 to shrink inward, and the tension of the friction belt 4 is reduced. At this time, the agricultural products in the climbing section are protected and supported by the rubber frame 764, the weight of the agricultural products has small downward pushing force on the friction belt 4, and the agricultural products in the straight running section of the friction belt 4 will not cause the friction belt 4 to slide, the hydraulic cylinder 32 drives the sliding push plate 33 to correct the deflection of the friction belt 4, and the friction belt 4 will not cause the agricultural products to roll and damage when it is corrected.
