Description

Technical Field

[0001] The present invention relates to the technical field of reclaimers, and particularly relates to a single-bucket reclaimer and an operation method thereof. Background Art

[0002] As an important loading, unloading and conveying device, reclaimers are widely used in large raw material yards in fields such as power plants, steel mills and docks. A reclaimer usually includes a traveling mechanism, a slewing mechanism, a pitching steel structure and a bucket wheel mechanism, etc. The bucket wheel mechanism is used to dig the material pile. The weight of the bucket wheel mechanism is usually between ten tons and more than twenty tons. The bucket wheel drive is powered by a drive motor. The weight, manufacturing cost and operation cost of the bucket wheel mechanism are relatively high. At the same time, it also increases the weight of the counterweight at the rear of the upper steel structure, making the whole reclaimer heavy, resulting in difficulties in transportation, storage, hoisting and positioning. For example, a bucket wheel reclaimer disclosed in Chinese Patent CN104444417A uses a bucket wheel mechanism to dig materials, and inevitably has a large overall weight due to the weight of the bucket wheel. Summary of the Invention

[0003] In order to solve the problems of the large weight, high manufacturing and operation costs of the reclaimer, the present invention provides a single-bucket reclaimer and an operation method thereof, which greatly reduce the overall weight of the machine, reduce the manufacturing cost, achieve the purpose of lightweight design of the structure, and also have good use and economic value.

[0004] In order to achieve the above object, the technical solution of the present invention is as follows:

[0005] A single-bucket reclaimer includes a pitching steel structure, a traveling device and a slewing device arranged under the pitching steel structure. A reclaiming mechanism and a conveying mechanism located below the reclaiming mechanism are arranged on the front arm frame of the pitching steel structure. The reclaiming mechanism includes a support frame and a digging bucket. The support frame is slidably connected to the front arm frame. The digging bucket is arranged on the support frame and is used for digging materials.

[0006] Further, the support frame includes a transverse frame and a vertical frame. The transverse frame is slidably arranged on the front arm frame. One end of the transverse frame is fixedly connected to the vertical frame, and they are combined into an "┛" shape. The lower end of the vertical frame is hinged to the digging bucket, and the upper end is connected to the digging bucket through a second telescopic mechanism.

[0007] Further, the other end of the transverse frame is connected to the front arm frame through a first telescopic mechanism.

[0008] Further, a plurality of guiding brackets are fixedly arranged on the front arm frame. Guiding wheels are arranged corresponding to the upper and lower sides of the guiding brackets. Guiding tracks matching the guiding wheels are arranged on both sides of the transverse frame. The guiding tracks are slidably arranged on the guiding wheels.

[0009] Furthermore, a reinforcing frame is fixedly arranged between the transverse frame and the vertical frame.

[0010] Furthermore, a receiving hopper is arranged at the front end of the front arm frame. The receiving hopper is located between the material taking mechanism and the conveying mechanism. The front side plate of the receiving hopper extends forward to the front end of the front arm frame, and the inclination angle of the front side plate of the receiving hopper is smaller than that of the rear side plate.

[0011] Furthermore, a flow regulating plate is slidably arranged on the rear side plate of the receiving hopper. The flow regulating plate is located at the discharge port of the receiving hopper, and a third telescopic mechanism is arranged between the flow regulating plate and the receiving hopper.

[0012] Furthermore, the conveying mechanism is a belt conveying mechanism, and the redirecting roller of the belt conveying mechanism is rotatably arranged at the front end of the front arm frame.

[0013] An operation method of a single-bucket material taking machine includes the following steps:

[0014] Step A: The whole machine moves forward towards the material pile;

[0015] Step B: After the front end of the receiving hopper contacts the material, the whole machine stops moving forward;

[0016] Step C: According to the material accumulation situation, the first telescopic mechanism extends or contracts to move the material taking mechanism back and forth, and the second telescopic mechanism extends or contracts until the digging bucket is in a digging state in front of the receiving hopper;

[0017] Step D: The second telescopic mechanism extends, the digging bucket digs the material, and the first telescopic mechanism contracts to introduce the material taken by the material taking mechanism into the receiving hopper;

[0018] Step E: The material in Step D falls onto the conveying mechanism through the receiving hopper and is transported to the next process.

[0019] Furthermore, in Step D, the movement of the flow regulating plate is controlled by the third telescopic mechanism to control the size of the discharge port of the receiving hopper.

[0020] By the above technical solutions, the beneficial effects of the present invention are as follows:

[0021] In the present invention, a material taking mechanism is arranged on the front arm frame of the pitching steel structure. The material taking mechanism includes a support frame and a digging bucket. The material taking mechanism is driven by the first telescopic mechanism to move towards the material pile, and the digging bucket is driven by the second telescopic mechanism to dig the material and introduce the material into the receiving hopper. The material is transported out through the conveying mechanism below the receiving hopper. The present invention uses a single digging bucket to dig the material, replacing the bucket wheel mechanism in the prior art, greatly reducing the weight of the whole machine, achieving the purpose of lightweight design of the structure, and the structure of the present invention is simple and easier to operate, having good use and economic value.

Detailed Embodiments

[0034] The present invention will be further described below in conjunction with the drawings and detailed embodiments:

[0035] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "transverse", "vertical", etc. are based on the attached Figure 1For the orientation or positional relationship shown, the direction in which the whole machine moves towards the material pile is "front", and vice versa is "rear". This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0036] As Figures 1 to 7 shown, this embodiment provides a single-bucket reclaimer, which includes a pitching steel structure 1, a traveling device and a slewing device (not shown in the figure) arranged under the pitching steel structure. A material taking mechanism and a conveying mechanism located below the material taking mechanism are arranged on the front arm frame 101 of the pitching steel structure 1. The material taking mechanism includes a support frame 2 and a digging bucket 3. The support frame 2 is slidably connected to the front arm frame 101, and the digging bucket 3 is arranged on the support frame 2 for digging materials. The present invention digs materials through a single digging bucket 3, replacing the bucket wheel mechanism in the prior art, greatly reducing the weight of the whole machine and achieving the purpose of lightweight structural design.

[0037] Further, the support frame 2 includes a transverse frame 201 and a vertical frame 202. The transverse frame 201 is slidably arranged on the front arm frame 101. One end of the transverse frame 201 is fixedly connected to the vertical frame 202, combined into an "┛" shape. The lower end of the vertical frame 202 is hinged to the digging bucket 3, and the upper end is connected to the digging bucket 3 through a second telescopic mechanism 8. In this embodiment, the second telescopic mechanism 8 is an oil cylinder. Driven by the expansion and contraction of the second telescopic mechanism 8, the digging bucket 3 moves towards the material pile to dig materials.

[0038] Specifically, the other end of the transverse frame 201 is connected to the front arm frame 101 through a first telescopic mechanism 4. In this embodiment, the first telescopic mechanism 4 is an oil cylinder. One end of the first telescopic mechanism 4 is connected to the front arm frame 101, and the other end is connected to the transverse frame 201. A plurality of guide brackets 5 are fixedly arranged on the front arm frame 101. The guide brackets 5 are in the shape of a "mouth". There are two guide brackets 5 in this embodiment. Guide wheels 501 are arranged corresponding to the upper and lower sides of the guide brackets 5. A groove for guiding is arranged on the outer circumferential end face of the guide wheels 501. Guide rails 203 matching the guide wheels 501 are arranged at the upper and lower ends on both sides of the transverse frame 201. The guide rails 203 are block-shaped ridges matching the grooves. The guide rails 203 are slidably connected to the guide wheels 501. By the expansion and contraction of the first telescopic mechanism 4, the transverse frame 201 slides back and forth along the front arm frame 101, and then drives the material taking mechanism to slide back and forth.

[0039] Further, a receiving hopper 6 is also arranged at the front end of the front arm frame 101. The receiving hopper 6 is located between the material taking mechanism and the conveying mechanism, as Figure 5As shown in the figure, the material receiving hopper 6 includes a front side plate, a rear side plate, and left and right side plates connecting the front and rear side plates. The front side plate of the material receiving hopper 6 extends forward to the front end of the front boom 101. The inclination angle of the front side plate of the material receiving hopper 6 is smaller than that of the rear side plate, forming a shape extending towards the front end of the front boom 101. More specifically, a distance detector is provided at the front end of the material receiving hopper 6 to detect whether the front end of the material receiving hopper 6 contacts the material. During the excavation operation, after the digging bucket 3 digs the material, driven by the retraction of the first telescopic mechanism 4, the material taking mechanism moves backward. The digging bucket 3 first contacts the upper end of the material receiving hopper 6, causing the material to fall into the material receiving hopper 6. The material slides down along the slope of the front side plate of the material receiving hopper 6 to the discharge port, and then falls onto the conveying mechanism.

[0040] Further, a flow rate regulating plate 601 is slidably provided on the rear side plate of the material receiving hopper 6. The flow rate regulating plate 601 is located at the discharge port of the material receiving hopper 6. A third telescopic mechanism 602 is provided between the flow rate regulating plate 601 and the material receiving hopper 6. The third telescopic mechanism 602 is an oil cylinder. By the expansion and contraction of the third telescopic mechanism 602, the flow rate regulating plate 601 is driven to move, regulating and controlling the size of the discharge port of the material receiving hopper 6, controlling the flow rate of the falling material, and playing a role in temporarily storing the material.

[0041] Further, in order to increase the strength of the support frame 2, a reinforcing frame 204 is fixedly provided between the horizontal frame 201 and the vertical frame 202. In this embodiment, one end of the reinforcing frame 204 is fixedly provided at the upper end of the vertical frame 202, and the other end of the reinforcing frame 204 is fixedly provided in the middle of the horizontal frame 201, between the two guiding brackets 5.

[0042] Further, the conveying mechanism is a belt conveying mechanism. The front end of the belt conveying mechanism is located in front of the discharge port of the material receiving hopper 6. The redirecting roller 7 of the belt conveying mechanism is rotatably provided at the front end of the front boom 101. When the material falls from the discharge port, the material is driven by the belt conveying mechanism and transported to the next process.

[0043] As Figures 8 to 11 shown, this embodiment also provides an operation method of a single-bucket material taking machine, including the following steps:

[0044] Step A: The whole machine advances towards the material pile;

[0045] Step B: After the front end of the material receiving hopper 6 contacts the material, the whole machine stops advancing;

[0046] Step C: According to the material accumulation situation, the first telescopic mechanism 4 extends or contracts to move the material taking mechanism forward and backward, and the second telescopic mechanism 8 extends or contracts until the digging bucket 3 is in a digging state in front of the material receiving hopper 6, as Figure 9 shown;

[0047] Step D: The second telescopic mechanism 8 extends, the bucket 3 digs for materials, the first telescopic mechanism 4 contracts, and the material taking mechanism introduces the materials into the receiving hopper 6, as Figure 10 and Figure 11 shown;

[0048] Step E: The materials in Step D fall onto the conveying mechanism through the receiving hopper 6 and are transported to the next process.

[0049] Furthermore, in Step D, the movement of the flow regulating plate 601 is controlled by the third telescopic mechanism 602 to control the size of the discharge port of the receiving hopper 6 and the flow rate of the falling materials, which can also play a role in temporarily storing the materials.

[0050] The structure of the present invention is simple, greatly reducing the weight of the whole machine. It is light in weight and easy to operate, with better operation sensitivity. It also has better application advantages in aspects such as transportation, storage, hoisting, and positioning of the whole machine, and at the same time has good application and economic value.

[0051] The above-described embodiments are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics, and principles described in the scope of the present invention patent shall be included in the scope of the present invention's patent application.
