Description

Technical Field

[0001] This invention belongs to the field of material transportation technology, and specifically relates to an automatic bucket wheel orientation device for a mixing and feeding machine. Background Technology

[0002] A mixing and reclaiming machine is a process equipment that uses a rotating bucket wheel with a hopper to mix and reclaim materials. It is mainly used in industries such as metallurgy, non-ferrous metals, and power generation, enabling the mixing of bulk materials such as ores. When the mixing and reclaiming machine reaches the end of the material yard, the hopper needs to be reversed to collect material in the opposite direction. In traditional mixing and reclaiming machines, when the machine completes material collection in one direction and needs to return to the starting direction, the rotation direction of the bucket wheel and the wheel itself must be reversed. This reversal operation can only be done manually, consuming a significant amount of valuable production time, manpower, and resources. Due to this problem, mixing and reclaiming machines have not been able to achieve fully intelligent and unmanned operation, hindering the intelligent upgrading of related industries. Summary of the Invention

[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing an automatic bucket wheel adjustment device for a mixing and reclaiming machine. This invention enables fully automatic adjustment of the bucket wheel of the mixing and reclaiming machine, saving manpower and time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] This invention provides an automatic bucket wheel reversing device for a mixing and feeding machine, comprising a bucket wheel body and a plurality of buckets arranged in a circumferential array on the bucket wheel body. The ends of the buckets are rotatably pinned to the bucket wheel body at their central axis ends. The device is characterized in that each bucket has a left limiting round steel and a right limiting round steel on either side of its central axis. A portal-shaped support frame is provided on the outer side of the bucket wheel body. A baffle is hinged to the support frame above and to the side of the bucket wheel body. The baffle is located between the left and right limiting round steels. A retractable push rod is also provided on the support frame. The end of the push rod corresponds to the side of the baffle and is used to push the baffle. When the buckets are reversing, the lowest points of the left and right limiting round steels are both lower than the lowest end face of the baffle after it is pushed out by the push rod, and the highest points of the left and right limiting round steels are both higher than the lowest end face of the baffle after it is pushed out by the push rod and can touch the side edge of the baffle.

[0006] Furthermore, a tension spring is provided between the bucket wheel body and each of the buckets, and the two ends of the tension spring are respectively connected to the bucket wheel body and the buckets via connecting rods.

[0007] Furthermore, all the connecting rods are U-shaped arc structures, the connecting rods are fixed to the bucket wheel body and the bucket wheel, and the end of the tension spring is sleeved on the connecting rod and can slide within the U-shaped arc of the connecting rod.

[0008] Furthermore, a detection switch is provided on the support frame at the position of the bucket wheel that is being tilted and oriented.

[0009] The beneficial effects of the present invention.

[0010] This invention enables fully automatic bucket wheel reorientation, saving manpower and time, and facilitating the intelligent upgrading of the entire material yard. Its structure and working principle are simple and easy to implement, and it can reduce the probability of failure by using fewer parts. Attached Figure Description

Detailed Implementation

[0018] As shown in the accompanying drawings, this embodiment provides an automatic bucket wheel 2 steering device for a mixing and feeding machine, including a bucket wheel body 1 and a plurality of bucket wheels 2 arranged in a circumferential array on the bucket wheel body 1. The ends of the central axes of the bucket wheels 2 are rotatably pinned to the bucket wheel body 1. The bucket wheels 2 move with the rotation of the bucket wheel body 1 and can pick up materials through the shovels at both ends.

[0019] The bucket wheel 2 is equipped with a left limiting round steel 3 and a right limiting round steel 4 on both sides of the central axis. Each time the bucket wheel 2 performs a bucket changing operation, one of them plays a flipping role, and the other plays a buffering role.

[0020] A portal-shaped support frame 5 is provided on the outside of the bucket wheel body 1. A baffle 6 is suspended and hinged on the support frame 5 above the side of the bucket wheel body 1. The baffle 6 is located between the left limiting round steel 3 and the right limiting round steel 4 and can swing towards or away from the bucket wheel 2 through the hinge shaft.

[0021] The support frame 5 is also equipped with a telescopic push rod 7, the end of which corresponds to the side of the baffle 6 and is used to push the baffle 6.

[0022] When the bucket wheel 2 is tilted and oriented, the lowest points of the left limit round steel 3 and the right limit round steel 4 are both lower than the lowest end face of the baffle 6 after it is pushed out by the push rod 7, ensuring that the bucket wheel 2 can pass through the baffle 6 before tilting; the highest points of the left limit round steel 3 and the right limit round steel 4 are both higher than the lowest end face of the baffle 6 after it is pushed out by the push rod 7 and can touch the side edge of the baffle 6, ensuring that the baffle 6 can block the left limit round steel 3 or the right limit round steel 4 at the highest point and tilt the bucket wheel 2 as the bucket wheel body 1 rotates.

[0023] A tension spring 8 is installed between the bucket wheel body 1 and each bucket 2. Both ends of the tension spring 8 are connected to the bucket wheel body 1 and the bucket 2 via connecting rods 9. The connecting rods 9 are all U-shaped arc structures. The connecting rods 9 are fixed to the bucket wheel body 1 and the bucket 2, and the ends of the tension spring 8 are sleeved on the connecting rods 9 and can slide within the U-shaped arc of the connecting rods 9. During the rotation of the bucket 2, the tension spring 8 extends and retracts while its ends slide within the U-shaped arc, maximizing space utilization within a limited space. This increases the lever arm of the tension spring 8 on the rotation point of the fixed pin and minimizes the size of the tension spring 8, saving space.

[0024] A detection switch 10 is installed on the support frame 5 at the position of the corresponding bucket 2 that is flipped and adjusted, which is used to identify the number of buckets 2 that have changed direction and to detect whether all buckets 2 have completed the adjustment.

[0025] The usage method and principle are as follows:

[0026] With attachment Figure 2 , 3 Taking the cases shown in 4 and 5 as examples, after normal installation, the bucket wheel body 1 first rotates counterclockwise. Due to the pre-tension of the tension spring 8, the right side of the bucket wheel 2 moves towards the periphery of the bucket wheel body 1, thus fixing the bucket wheel 2. The left side of the bucket wheel 2 then uses the shovel to pick up material.

[0027] When the mixing and feeding machine needs to reverse and collect material through the right-side shovel of the bucket wheel 2, the bucket wheel 2 needs to be adjusted in direction, such as... Figure 2As shown, at this time, push rod 7 is pushed out, pushing baffle 6 to swing towards the inner side of bucket 2, between the left limiting round steel 3 and the right limiting round steel 4 on bucket 2. After baffle 6 is in place, bucket wheel 1 rotates clockwise, as shown. Figure 3 As shown, when the wheel bucket 2 reaches the position of the baffle 6, the right limit round steel 4 of the wheel bucket 2 at the low point first passes through the lower end of the baffle 6, and then the push plate collides with the left limit round steel 3 at the high point to start flipping and adjusting direction.

[0028] like Figure 4 As shown, the bucket wheel 2 needs to overcome the tension of the tension spring 8 while rotating. After the bucket wheel 2 rotates around its fixed pin and passes its central axis, under the action of gravity and the tension of the tension spring 8, the bucket wheel 2 will accelerate and flip. However, due to the presence of the right limiting round steel 4 of the bucket wheel 2, the right limiting round steel 4 will collide with the side of the baffle 6, causing the bucket wheel 2 to slowly complete the subsequent flipping as the bucket body rotates. The right limiting round steel 4 plays a buffering and protective role until it collides with the left end of the bucket wheel 2 and the bucket wheel body 1, completing the flipping. Figure 5 As shown, the left limit round steel 3 will pass under the push plate without interfering with other components. When the shovel opening on the side of the bucket 2 used for picking up material (the right shovel opening) flips to contact the periphery of the wheel body, the tension of the tension spring 8 will firmly fix the bucket 2 to the bucket wheel body 1. At this time, the orientation of a single bucket 2 is completed. This process continues until the picking direction of all buckets 2 is changed, and the detection switch 10 is used for identification and confirmation.

[0029] If each bucket wheel 2 needs to be adjusted in the opposite direction to the above process, the bucket wheel body 1 can be changed from clockwise rotation to counterclockwise rotation and carried out in accordance with the above principle.

[0030] It is understood that the above specific description of the present invention is only for illustrating the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of the present invention.
