Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a cleaning mechanism for a fertilizer conveying belt machine. Background Art

[0002] Fertilizer is a material basis that can improve soil properties and increase soil fertility levels. It is widely used in agricultural production because it can provide nutrients required for crop growth and development, thereby increasing crop yield and quality.

[0003] In the process of fertilizer production, in order to facilitate its transportation, transfer and packaging, belt conveyors are often required. However, fertilizers are easy to adhere to the belts during the transportation process, causing inconvenience to subsequent use. Therefore, in order to ensure product production quality, the belts need to be cleaned in time.

[0004] For example, in the patent document with patent publication number CN216661483U, a fertilizer conveyor belt machine with a self-cleaning function is disclosed, which includes a support frame, a belt conveyor body and a collecting bucket. The top of the support frame is fixedly installed with the belt conveyor body with one end extending into the interior of the support frame, and the bottom of the support frame is fixedly installed with four support rods extending into the interior of the collecting bucket. The outer sides of the two left support rods are movably installed with a scraping brush mechanism whose one end contacts the belt conveyor body, and the opposite sides of the two support rods on the same side are fixedly installed with the fixed frame, and the opposite sides of the two fixed frames are fixedly installed with the guide rod, and the outer sides of the guide rod are movably installed with a roller brush, and the top of the front fixed frame is fixedly installed with an electric push rod whose output end is movably installed with the roller brush, and the opposite sides of the two right support rods are fixedly installed with the material baffle plate, and the bottom of the collecting bucket is connected to a negative pressure separation mechanism.

[0005] According to the existing technical literature, the conveyor belt can drive the scraper to scrape the belt through the electric telescopic rod, and the roller brush can be driven by the electric push rod to brush the belt, so as to clean the fertilizer adhering to the belt. However, the scraper may produce some rubber crumbs due to the friction of the belt, and the bristles of the roller brush are easy to fall off after long-term use. However, under the action of the centrifugal fan, these rubber crumbs and bristles are easy to mix into the cleaned fertilizer, and then be recycled together with it, which ultimately affects the product quality.

[0006] To this end, the utility model optimizes and improves the problem in the prior art that fertilizers recovered after cleaning are easily mixed with foreign matter. A new cleaning mechanism is proposed, which can clean the fertilizers adhered to the conveyor belt through vibration force, so as to better solve the problems in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0030] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 7 as shown in .

[0031] A fertilizer conveyor belt cleaning mechanism comprises two fixed beams 1, the two beams 1 are spaced apart and arranged in parallel, a plurality of supporting rollers 2 are spaced apart along the length direction in the space between the two beams 1, the ends of the central rotating shaft 3 of each supporting roller 2 are movably inserted into the rotating hole of the beam 1 at the corresponding position, a cutting assembly, a vibration assembly and a tension adjustment assembly are spaced apart from right to left below the two beams 1, and also comprises an annular conveyor belt 4, the upper belt of the conveyor belt 4 is pressed against the top of the rolling surface of each supporting roller 2, the right end of the lower belt of the conveyor belt 4 passes through the cutting assembly and is pressed against the top thereof, the middle section of the lower belt of the conveyor belt 4 is pressed against the bottom of the vibration assembly, and the left end of the lower belt of the conveyor belt 4 passes through the tension adjustment assembly and is pressed against the top thereof.

[0032] The two beams 1 are fixedly arranged by a plurality of first legs 25. The support roller 2 at the leftmost end of the beam 1 is used as a driving roller, and a pulley 29 is coaxially fixedly connected to one end of the central rotating shaft 3. The pulley 29 is connected to an external motor by belt transmission, so that the support roller 2 can drive the conveyor belt 4 to rotate continuously.

[0033] The conveyor belt 4 rotates clockwise, and its upper belt continues to move to the lower position after conveying the fertilizer, and passes through the cutting component, the vibration component and the tension adjustment component in sequence. Under the action of the cutting component, the fertilizer adhering to the conveyor belt 4 in a large area can be cut and divided into blocks, so that a part of the fertilizer can be preliminarily cleaned. Under the action of the vibration component, the conveyor belt 4 passing through this place can be vibrated, so that the fertilizer still remaining on the conveyor belt 4 after the action of the cutting component can be further cleaned, so that it falls from the conveyor belt 4 under the action of the vibration force. At the same time, after long-term use, under the continuous vibration of the vibration component, the conveyor belt 4 will gradually relax, thereby affecting the work of the vibration component. Therefore, in order to avoid this situation, it is ensured that the conveyor belt 4 always has a certain tension, so that the vibration component can better vibrate the conveyor belt 4. The utility model is provided with a tension adjustment component, so that the tension of the conveyor belt 4 can be adjusted after long-term use.

[0034] In any of the above schemes, it is preferred that the vibration assembly includes two pressure members arranged at intervals in the horizontal direction, and the lower ends of the two pressure members respectively press against the corresponding positions of the inner side surface of the lower belt of the conveyor belt 4, and the crossbeam 1, the lower belt of the conveyor belt 4 and the two pressure members together form a placement space 5, and a vibration member is fixedly installed in the placement space 5, and the vibration surfaces of the lower part of the vibration member are all fitted on the inner side surface of the lower belt of the conveyor belt 4.

[0035] The vertical overall length of the pressing member is longer than that of the slitting assembly and the tension adjusting assembly, so that under the cooperation and pressing of the slitting assembly and the tension adjusting assembly, the two pressing members push the middle section of the lower belt of the conveyor belt 4 downward, so that the conveyor belt 4 at this location is away from the bottom of each supporting roller 2, and then a placement space 5 is formed between the crossbeam 1, the lower belt of the conveyor belt 4 and the two pressing members.

[0037] The mounting plate 6 is fixedly arranged by the second support leg 26, and the vibration motor 7 is fixedly installed at the bottom of the mounting plate 6 by the bracket 28. When the vibration motor 7 is working, its vibration surface vibrates the lower belt of the conveyor belt 4, thereby vibrating and cleaning the fertilizer adhered to the outer surface of the conveyor belt 4 passing therethrough.

[0038] In any of the above schemes, it is preferred that the pressure member includes two first connecting frames 8, the upper ends of the two first connecting frames 8 are respectively fixedly connected to the bottom of the corresponding cross beam 1, and also includes a first rotating rod 9, the two ends of the first rotating rod 9 are respectively movably inserted into the rotating holes of the first connecting frames 8 at corresponding positions, and a pressure roller 10 is coaxially fixedly sleeved on the middle section of the first rotating rod 9, and the corresponding position of the lower part of the rolling surface of the pressure roller 10 presses on the inner surface of the lower belt of the conveyor belt 4.

[0039] The first connecting frame 8 is fixedly installed at the corresponding position at the bottom of the beam 1 in the vertical direction. The first rotating rod 9 and the pressure roller 10 are installed at the corresponding positions below the beam 1 through the two first connecting frames 8. At the same time, the pressure roller 10 can rotate freely around the axial direction of the first rotating rod 9.

[0040] The circumferential rolling surface of the pressing roller 10 presses against the inner side surface of the lower belt of the conveyor belt 4. At the same time, under the action of the first connecting frame 8, the middle section of the lower belt of the conveyor belt 4 is pushed downward for a certain distance, thereby facilitating the placement of the vibration motor 7.

[0041] In any of the above schemes, it is preferred that the slitting assembly includes two second connecting frames 11, the upper ends of the two second connecting frames 11 are respectively fixedly connected to the bottom of the corresponding cross beam 1, and also includes a second rotating rod 12, the two ends of the second rotating rod 12 are respectively movably inserted into the rotating holes of the second connecting frames 11 at corresponding positions, and a slitting roller 13 is coaxially fixedly sleeved on the middle section of the second rotating rod 12, and a plurality of slitting teeth 14 are provided on the circumferential rolling surface of the slitting roller 13 along its axial direction, and the corresponding positions of the upper parts of the slitting teeth 14 are respectively pressed against the outer surface of the lower belt of the conveyor belt 4.

[0042] The cutting teeth 14 are arranged in a ring shape on the circumferential rolling surface of the cutting roller 13. The fertilizer adhering to the outer surface of the lower belt of the conveyor belt 4 can be cut by the cutting teeth 14. At the same time, a chamfer is set on the outer abutting end of the cutting teeth 14 to prevent the cutting teeth 14 from damaging the conveyor belt 4 body when abutting against the conveyor belt 4.

[0043] In any of the above schemes, it is preferred that the tension adjustment assembly includes two third connecting frames 15, and adjusting pieces are respectively provided at corresponding positions at the bottom of the two cross beams 1, and the upper ends of the two third connecting frames 15 are respectively mounted on the corresponding adjusting pieces, and also includes a third rotating rod 16, and the two ends of the third rotating rod 16 are respectively movably inserted into the rotating holes of the third connecting frames 15 at corresponding positions, and an adjusting roller 17 is coaxially fixedly sleeved on the middle section of the third rotating rod 16, and the corresponding position of the upper part of the rolling surface of the adjusting roller 17 is pressed against the outer surface of the lower belt of the conveyor belt 4.

[0044] In the initial state, the adjusting roller 17 is fixed at the corresponding position by the third connecting frame 15. At this time, the conveyor belt 4 between the adjusting roller 17 and the pressure roller 10 on the left is in the vertical direction. When the conveyor belt 4 becomes loose after long-term use, the two third connecting frames 15 are synchronously displaced horizontally to the right through the adjusting member, so that the adjusting roller 17 is translated to the right, and then the conveyor belt 4 at this position is pressed to move to the right, and finally the tension of the entire conveyor belt 4 is increased until the lower belt of the conveyor belt 4 can continue to achieve a good vibration effect under the action of the vibration motor 7.

[0045] In any of the above schemes, it is preferred that the adjusting member includes a linear guide rail 18 fixedly connected to the bottom of the beam 1 along the length direction of the beam 1, a slider 19 is fixedly connected to the upper end of the third connecting frame 15, the slider 19 is slidably connected to the linear guide rail 18, a connecting plate 20 is fixedly connected to the vertical side wall of the slider 19, the upper end of the connecting plate 20 extends to the corresponding side of the beam 1 along the vertical direction, and also includes a plurality of matching connecting bolts 21, a plurality of through holes for the connecting bolts 21 to pass through are provided at intervals on the upper part of the connecting plate 20, a plurality of positioning threaded holes 30 are evenly spaced along the length direction at corresponding positions of the vertical side walls of the beam 1, and each of the connecting bolts 21 is threadedly connected to the positioning threaded hole 30 at the corresponding position in the working state.

[0046] The slider 19 moves along the linear guide rail 18, thereby driving the third connecting frame 15 to move horizontally, thereby finally realizing the horizontal displacement of the adjusting roller 17 relative to the left pressing roller 10. A connecting plate 20 is welded on the outer vertical side wall of the slider 19 in the vertical direction, two through holes are provided at intervals on the upper part of the connecting plate 20, and a plurality of positioning threaded holes 30 are evenly provided at intervals on the outer vertical side wall of the crossbeam 1, and the spacing between two adjacent positioning threaded holes 30 is equal to the spacing between the two through holes, so that the slider 19 is fixed through the matching connection of the positioning bolt 30, the through hole and the positioning threaded hole 30, thereby realizing the positioning operation of the adjusting roller 17.

[0047] In any of the above schemes, it is preferred that it further includes a fixed air duct 22, the inner end of which extends below the lower belt of the conveyor belt 4, and a negative pressure fan 23 is fixedly installed in the inner cavity of the inner end of the air duct 22.

[0048] Under the action of the vibration motor 7, the fertilizer that remains on the conveyor belt 4 after cutting can be cleaned up. Under the action of the negative pressure fan 23, the inner end of the air duct 22 can suck out the fertilizer dust that falls and floats in the air, and then discharge it to the corresponding work station through the outer end of the air duct 22.

[0049] In any of the above solutions, preferably, a collection pool 24 is fixedly provided below the air duct 22 .

[0050] The collecting pool 24 is supported by the third support leg 27, and the inside of the collecting pool is used to contain the fertilizer particles dropped by the cutting and vibration operations, and then to recycle them.

[0051] Specific working principle:

[0052] The fertilizer is placed on the left end of the upper belt of the conveyor belt 4, and then the pulley 29 is driven to rotate by the external motor, thereby rotating the corresponding supporting roller 2, and further rotating the conveyor belt 4 clockwise, thereby transferring the fertilizer from the left end of the conveyor belt 4 to the right end and completing the packaging and other tasks, and then the remaining fertilizer adhering to the conveyor belt 4 continues to move with it.

[0053] Afterwards, under the action of the cutting teeth 14, the fertilizer adhering to a large area is initially cut and cleaned, and the fallen fertilizer particles are collected in the collecting pool 24. Then the adhering residual fertilizer continues to move with the conveyor belt 4, and under the vibration of the vibration motor 7, it is separated from the lower belt of the conveyor belt 4, and the collecting pool 24 continues to collect the fertilizer particles that fall there, and at the same time, the air duct 22 sucks the cleaned fertilizer dust under the action of the negative pressure fan 23. After that, the conveyor belt 4 continues to rotate to the upper side of the left end of the beam 1, and then continues to carry out the transportation and packaging of the fertilizer.

[0054] At the same time, through the cooperation connection between the slider 19 and the linear guide rail 18, the adjusting roller 17 can move relative to the pressure roller 10 on the left side, so as to adjust the tension of the conveyor belt 4 and ensure the good operation of the device.
