DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 7As shown, in the embodiment of the utility model, a material distributing device for urea transportation includes a conveying device 1, support legs 2 are fixedly installed on both sides of the conveying device 1, a support frame 3 is arranged above the conveying device 1, a fixed ear plate 4 is fixedly installed on the top of the support frame 3, a pneumatic actuator 5 is installed inside the fixed ear plate 4, one end of the pneumatic actuator 5 is hinged with a connecting beam 6, the connecting beam 6 is fixedly installed on the inner wall of the baffle bracket 7, both ends of the baffle bracket 7 are installed with fixed plates 14, the fixed plate 14 is fixedly installed inside the support frame 3, a baffle plate 8 is installed on one side of the baffle bracket 7, material receiving troughs 15 are installed on both sides of the conveying device 1, and material receiving boxes 16 are arranged below the two material receiving troughs 15.

[0034] When urea is divided, the urea on the conveying device 1 is divided into three flows when passing through the baffle plate 8. A part of the urea continues to flow forward along the conveying device 1 due to the height difference between the bottom end of the baffle plate 8 and the conveying device 1, and the other urea is blocked by the baffle plate 8 and flows to the receiving troughs 15 on both sides. The urea in the receiving troughs 15 flows into the corresponding receiving boxes 16 to complete the division.

[0035] Both ends of the baffle bracket 7 are rotatably connected to the fixing plate 14 through a pin shaft;

[0036] The pneumatic actuator 5 in this solution may also be a linear drive mechanism such as a telescopic cylinder or a linear drive motor;

[0037] When it is necessary to adjust the distribution amount, the pneumatic actuator 5 is extended and pulled to pull the baffle plate 8 to swing in the vertical direction along the pin shaft. The starting end of the V-shaped baffle plate 8 swings upward or downward, thereby changing the blocking area and blocking height of the baffle plate 8 for the urea on the conveying equipment 1. More urea on the conveying equipment 1 will pass through the baffle plate 8 and continue to be conveyed downward, while the urea on the conveying equipment 1 flowing into the receiving trough 15 will become less, thereby realizing the adjustment of the distribution amount, avoiding the problem that most of the existing diversion devices are equipped with a fixed baffle plate 8 above the conveyor belt for diversion, which is inconvenient to adjust the distribution amount, has a complex structure and high distribution adjustment accuracy, and ultimately leads to poor distribution effect, thereby improving the urea distribution effect.

[0038] like Figures 1 to 6 As shown, both ends of the baffle plate 8 are fixedly mounted with material guide folding plates 9, and the two material guide folding plates 9 are both inclined.

[0039] The falling direction of the blocked urea is guided so that the urea can enter the receiving box 16 through the receiving trough 15 .

[0040] like Figures 1 to 6 As shown, one side of the material blocking plate 8 is connected to a wear-resistant plate 10 via a mounting assembly.

[0041] The wear resistance of the baffle plate 8 is increased to effectively resist wear, thereby extending the service life of the equipment.

[0042] like Figure 6 As shown, the installation assembly includes a first connecting plate 11 fixedly installed on the top of the wear-resistant plate 10. The first connecting plates 11 are evenly arranged, and a fixing rod 12 is embedded inside each first connecting plate 11. The fixing rod 12 is fixedly installed on the top of the material baffle plate 8, and a limiting block 13 is fixedly installed on the top of the fixing rod 12.

[0043] Through the setting of the installation assembly, when the wear-resistant plate 10 needs to be replaced, the first connecting plate 11 is first pulled to deform the first connecting plate 11, and then the first connecting plate 11 is slid upward through the limit block 13 to remove the wear-resistant plate 10. The installation method is simple and convenient.

[0044] The first connecting plate 11 is elastically configured, such as rubber. Rubber has excellent elasticity and flexibility, can be deformed under the action of external force, and quickly return to its original shape after the external force is removed. It also has high wear resistance and can withstand long-term friction and use without being easily worn.

[0045] like Figures 1 to 7 As shown, a cleaning roller 17 is provided at the bottom of the conveying device 1, and a first rotating shaft 19 is embedded in the interior of the cleaning roller 17. Both ends of the first rotating shaft 19 are embedded in the interior of the supporting leg 2. The first rotating shaft 19 and the supporting leg 2 are rotatably connected via a rotating assembly. Bristles 18 are fixedly mounted on the outer wall of the cleaning roller 17, and the bristles 18 are evenly arranged. A knocking assembly is provided on one side of the cleaning roller 17, and a collecting box 27 is provided at the bottom of the cleaning roller 17.

[0046] After the conveying device 1 transfers urea, the bottom end of the conveying device 1 contacts the bristles 18, and the bristles 18 clean the bottom of the conveying device 1 to remove residual urea particles, which are collected by the cam 24 to prevent accumulation and adhesion, thereby ensuring smooth urea diversion and transmission processes.

[0047] like Figures 1 to 7 As shown, the rotating assembly includes a connecting block 20 fixedly mounted on the outer wall of the first rotating shaft 19, one end of the first rotating shaft 19 is fixedly connected to a first bevel gear 21, one side of the first bevel gear 21 is meshingly connected to a second bevel gear 22, the second bevel gear 22 is fixedly mounted on the outer wall of the second rotating shaft 31, and one end of the second rotating shaft 31 is mounted with a motor 23.

[0048] Through the setting of the rotating component, when urea is distributed, the motor 23 is started by PLC control, the start of the motor 23 drives the rotation of the second rotating shaft 31, the rotation of the second rotating shaft 31 drives the rotation of the second bevel gear 22, the rotation of the second bevel gear 22 drives the rotation of the first bevel gear 21, the rotation of the first bevel gear 21 drives the rotation of the first rotating shaft 19, the rotation of the first rotating shaft 19 drives the rotation of the bristles 18 through the connecting block 20, the rotation of the bristles 18 drives the rotation of the cleaning roller 17, so as to improve the cleaning effect on the bottom of the conveying equipment 1.

[0049] like Figures 1 to 7 As shown, the knocking assembly includes a knocking plate 25 arranged on one side of the cleaning roller 17, the knocking plate 25 is arranged below the conveying device 1, a first spring 26 is arranged at the top end of the knocking plate 25, a cam 24 is arranged at the bottom end of the knocking plate 25, and the cam 24 is fixedly mounted on one end of the second rotating shaft 31.

[0050] Through the setting of the knocking assembly, when the second rotating shaft 31 rotates, the cam 24 rotates, and the rotation of the cam 24 drives the knocking plate 25 to move upward, so that the knocking plate 25 contacts the bottom of the conveying equipment 1. When the knocking plate 25 moves upward, it squeezes the first spring 26 to deform so that it stores elastic potential energy, and the elastic potential energy is released by the first spring 26 to reset the knocking plate 25, thereby achieving a reciprocating knocking effect, knocking off the debris on the bottom of the conveying equipment 1, and further improving the cleaning effect of the conveying equipment 1.

[0051] like Figures 1 to 7 As shown, a second connecting plate 30 is disposed on one side of the cam 24 . The second connecting plate 30 is sleeved on the outer wall of the first rotating shaft 19 . The second connecting plate 30 is disposed at one end of the cleaning roller 17 .

[0052] When the cam 24 rotates, the rotation of the cam 24 drives the second connecting plate 30 to move, and the movement of the second connecting plate 30 drives the cleaning roller 17 to move, causing the cleaning roller 17 to shift laterally, thereby increasing the contact area between the bristles 18 and the bottom of the conveying device 1 and improving the cleaning effect.

[0053] like Figure 7 As shown, a connecting ring 29 is fixedly connected to one side of the second connecting plate 30 , and the connecting ring 29 is rotatably installed inside the cleaning roller 17 .

[0054] When the cleaning roller 17 rotates, the second connecting plate 30 does not rotate, so that it is always on one side of the cam 24 .

[0055] like Figure 5 As shown, a second spring 28 is provided at one end of the cleaning roller 17 away from the second connecting plate 30 .

[0056] When the cleaning roller 17 moves laterally, the second spring 28 is squeezed to store elastic potential energy, and releases the elastic potential energy to move the cleaning roller 17 back and forth, and cooperates with the cam 24 to make the cleaning roller 17 move laterally reciprocatingly.

[0057] Working principle and usage process:

[0058] When the material distribution amount needs to be adjusted, the pneumatic actuator 5 is extended and pulled to pull the baffle plate 8 to swing in the vertical direction along the pin shaft, and the starting end of the V-shaped baffle plate 8 swings upward or downward, thereby changing the baffle area and height of the baffle plate 8 for the urea on the conveying device 1. More urea on the conveying device 1 will pass through the baffle plate 8 and continue to be transported downward, while the urea on the conveying device 1 flowing into the receiving trough 15 will become less, thereby realizing the adjustment of the material distribution amount;

[0059] When urea is divided, the urea on the conveying device 1 is divided into three flows when passing through the baffle plate 8. A part of the urea continues to flow forward along the conveying device 1 due to the height difference between the bottom end of the baffle plate 8 and the conveying device 1, and the other urea is blocked by the baffle plate 8 and flows to the receiving troughs 15 on both sides. The urea in the receiving troughs 15 flows into the corresponding receiving boxes 16 to complete the division.

[0060] After the conveying device 1 transmits the divided materials, the bottom end of the conveying device 1 contacts the bristles 18 for cleaning, and at the same time, the motor 23 can be started by PLC control, and the start of the motor 23 drives the rotation of the second rotating shaft 31, and the rotation of the second rotating shaft 31 drives the rotation of the second bevel gear 22, and the rotation of the second bevel gear 22 drives the rotation of the first bevel gear 21, and the rotation of the first bevel gear 21 drives the rotation of the first rotating shaft 19, and the rotation of the first rotating shaft 19 drives the rotation of the bristles 18 through the connecting block 20, and the rotation of the bristles 18 drives the cleaning roller 17 to rotate to clean the bottom of the conveying device 1;

[0061] At the same time, the rotation of the second rotating shaft 31 drives the cam 24 to rotate, the rotation of the cam 24 drives the second connecting plate 30 and the knocking plate 25 to move, the movement of the second connecting plate 30 drives the cleaning roller 17 to move, so that the cleaning roller 17 is displaced laterally, and the knocking plate 25 moves to cooperate with the first spring 26 to knock on the bottom of the conveying equipment 1, and the impurities at the bottom of the conveying equipment 1 fall into the collection box 27 for collection.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
