Observation ports 17 are symmetrically opened on the left side of the work frame 2.

[0022] The utility model discloses a first guide plate 5 and second guide plate 10 are hinged respectively on the front side and rear side of the bottom of the working frame 2, and the flexible adjustment of guide plate is realized through the screw rod and universal joint, can effectively guide material evenly falls in the middle position of the transmission belt 1, and first guide plate 5, second guide plate 10 can be adjusted separately, adapts the falling angle and position of different materials, ensures that even when the transmission belt 1 cannot align the center line of the material port, material can also evenly fall on the transmission belt, avoids the impact of material instantaneous falling to the side position of the belt, thereby prevents the deviation of the belt, the utility model discloses still can through the angle of first guide plate 5 and second guide plate 10 is adjusted, can control the flow and impact force of material drop, avoids the deviation of transmission belt 1 due to the too big or offset of impact force, thereby improves the efficiency and stability of material transmission, the utility model discloses is equipped with walking wheel 16 in the bottom of working frame 2 front and back symmetry, and walking wheel 16 is closely contacted with transmission belt 1, and the transmission belt 1 is pressed and compacted, prevents the deviation of the belt to one side under the condition of not being forced, ensures that the transmission belt 1 keeps balance when receiving material, the utility model discloses is opened with observation port 17 in the left part of working frame 2 front and back symmetry, and the transmission of material on transmission belt 1 and the running state of the belt are observed conveniently for the staff, and the deviation condition is adjusted in time, ensures the normal operation of equipment.

[0023] Example 2

[0024] As Figures 1 to 4 The utility model discloses a kind of deviation-preventing devices of belt conveyor guide chute, including working frame 2, working frame 2 is installed in the position above transmission belt, and working frame 2 is extended triangle shape, can increase the installation stability of working frame 2 and component above working frame 2. Material port is opened in the top right side of working frame 2, material port is installed with feed pipe 4, i.e. material can be placed into, from top to bottom into feed pipe 4, immediately after guide chute out to slide down to the transmission belt below, transmission belt continuously rotates and can continuously transport material. Among them, feed pipe 4 is overall designed to right inclination, more convenient to connect with other processes, so that material can automatically slide down when entering the upper part of feed pipe 4, a certain angle of inclination can avoid material suspended drop, cause damage of different degrees, lead to subsequent unable to continue using, increase cost of loss.

[0025] The first guide plate 5 and the second guide plate 10 are symmetrically arranged, and the two can be used to close the material port after being rotated to the limit in the direction of the material port. It can be understood that when the transmission belt 1 is aligned with the center line of the first guide plate 5 and the second guide plate 10, a specified angle can be formed after the two guide plates are rotated to be opened, and the material can be guided by the first guide plate 5 and the second guide plate 10 to gather inwardly, so that the material can be uniformly dropped on the middle position of the transmission belt, and the impact of the instantaneous dropping of the material on the side position of the belt can be avoided, and the situation of the belt being inclined and deviated can be avoided. Moreover, the first guide plate 5 and the second guide plate 10 can be adjusted individually, so that the dropping angle and the dropping position required by different materials can be adjusted, and when the transmission belt cannot be aligned with the center line of the material port, the material can be uniformly dropped on the transmission belt.

[0026] Further, the adjusting port 15 is symmetrically opened on the right side of the workstand 2, the mounting plate is arranged at the bottom of the workstand 2 and below the adjusting port 15, the nut is arranged at the lower inner side of the mounting plate, the screw rod is rotatably arranged between the nut and the mounting plate, and in actual application, the adjusting valve can be arranged on the outer side of the screw rod for convenient operation. The screw rod is driven to rotate by rotating the adjusting valve, and then the screw rod is driven to move forward and backward on the mounting plate under the action of the nut. Thus, the screw rod is divided into the first screw rod 8 and the second screw rod 13, the first screw rod 8 is arranged at the front side of the first guide plate 5 and is rotatably connected with the first guide plate 5 through the first universal joint 9, and the second screw rod 13 is arranged at the rear side of the second guide plate 10 and is rotatably connected with the second guide plate 10 through the second universal joint 14. The universal joint specifically includes a ball valve and a connector, the connector is arranged on the outer side of the guide plate, and the ball valve is arranged on the inner side of the screw rod. It can be understood that the worker can operate the adjusting valve through the adjusting port 15, and the screw rod is driven to rotate reversely and move forward and backward at the same time. Specifically, the first screw rod 8 moves inwardly to drive the first guide plate 5 to rotate to the material port through the first universal joint 9, the first screw rod 8 moves outwardly to drive the first guide plate 5 to rotate outwardly, and the second screw rod 13 is opposite to the first screw rod 8.

[0027] Example 3

[0028] As Figures 1 to 4The conveyor belt guide chute anti-deviation device shown further includes symmetrically arranged traveling wheels 16 at the bottom of the work frame 2, located on the right side of the material inlet. The traveling wheels 16 are arranged laterally and are in the same direction of rotation as the conveyor belt 1. The installation height of the traveling wheels 16 needs to be set according to the height between the work frame 2 and the conveyor belt. The lowest point of the traveling wheels 16 needs to be in close contact with the conveyor belt 1. In this way, when the conveyor belt 1 rotates, it can be pressed and compacted in advance before the material is received and transferred, so as to prevent the conveyor belt 1 from deviating to one side when it is not under force, which would cause it to lose balance when receiving material later.

[0029] The aforementioned traveling wheels 16 can be directly welded and fixed to the bottom of the work frame 2, or they can be installed at the bottom of the work frame 2 via telescopic components such as cylinders. Thus, when there is a certain deviation in the thickness and height of the transmission belt 1, the height of the traveling wheels 16 can be adjusted to apply different forces. For example, when the transmission belt 1 is relatively thick, the traveling wheels 16 need to be adjusted downwards to ensure that the traveling wheels 16 can fit tightly against the transmission belt 1 and exert a pressing and compacting effect on the transmission belt 1 to prevent the belt from running off-track. When the height of the transmission belt 1 is adjusted up or down, the traveling wheels 16 can be driven to make corresponding adjustments to ensure that the traveling wheels 16 can adapt to transmission belts 1 of different heights, maintain a tight fit with the transmission belt 1, and exert a pressing and compacting effect on the transmission belt 1 to prevent the belt from running off-track.

[0030] Example 4

[0031] like Figures 1 to 4 In the conveyor belt guide chute anti-deviation device shown in Embodiment 2, a rotating screw is used to drive the guide plate to move inward and outward. A universal joint then flexibly connects the guide plate to the bottom of the work frame 2, causing the guide plate to rotate. During this process, the guide plate can be adjusted according to the actual situation and material flow rate. The first guide plate 5 and the second guide plate 10 can rotate synchronously, causing the angle between them to expand or contract. This controls the flow rate of falling material and the impact force on the conveyor belt 1 when the material falls, preventing excessive impact force or deviation that could cause the conveyor belt 1 to deviate. The above only applies to the case where the conveyor belt 1 and the material inlet are on the same center line. When the conveyor belt 1 and the material inlet are not on the same center line, the first guide plate 5 and the second guide plate 10 can be rotated separately, causing the channel between the first guide plate 5 and the second guide plate 10 to adjust back and forth until the channel and the conveyor belt 1 are on the same center line. This ensures that the material falling through the channel will also fall to the center position of the conveyor belt 1, preventing the conveyor belt 1 from deviating.

[0032] In example 3, the lowest point of the walking wheel 16 needs to be in close contact with the conveying belt 1, so that the conveying belt 1 can be compressed and compacted before the material is caught and conveyed, avoiding the conveying belt 1 from deviating to one side under the force, resulting in the subsequent material catching cannot keep balance.

[0033] That is, the top right side of the conveying belt 1 (set as section A), the section A moves left to contact the walking wheel 16, and keeps straight and tight under the pressure of the walking wheel 16, and then falls down to the section A through the first guide plate 5 and the second guide plate 10 when passing below the material port, and the section A continues to move left to convey the material. Considering that there is no any limiting setting on the section A, the material may deviate during the movement, resulting in the section A deviates, driving the whole conveying belt 1 to deviate, so the observation port 17 is symmetrically arranged on the left of the working frame 2, for observing the material and belt condition on the left side of the conveying belt 1, and checking and adjusting the deviation in time.

[0034] It should be noted that the relational terms herein such as first and second and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any such actual relationship or order between such entities or actions.
