Description

Technical Field

[0001] This utility model relates to the field of transmission shaft technology, and in particular to a sampler for a belt head transmission shaft. Background Technology

[0002] Currently, the head sampler for coke sampling uses a rotary receiving method. Rotary receiving means that during the material conveying process, the sampler rotates 360° at the discharge port to receive the material. It is also called the transverse receiving method. Using this method, all the material in the cross section of the entire material flow can be sampled, which has the characteristic of strong sample representativeness.

[0003] However, when rotating to receive materials, the receiving hopper needs to cut off the material flow to receive samples. Due to the high rotation speed and the large impact force of the material flow, the rotating shaft of the receiving hopper is over-assisted, which often leads to deformation, breakage and other malfunctions, affecting the normal operation of the equipment.

[0004] Replacing the drive shaft requires disassembling the entire reducer, which is time-consuming and labor-intensive, severely impacting the timeliness of incoming coke quality inspection and unloading efficiency. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0024] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0025] like Figure 1-3 As shown, this utility model embodiment discloses a belt head drive shaft sampling machine, including a reducer 1, a transmission mechanism 2, a rotating cylinder 3, a fixing mechanism 5, and a receiving hopper 4;

[0026] The reducer 1 is vertically mounted on the upper end of the fixed bracket via a screw. The reducer 1 will not shake when it is running. The shaft inlet of the reducer 1 is connected to one end of the transmission mechanism 2. The other end of the transmission mechanism 2 is detachably connected to the top of the rotating cylinder 3. In order to make the rotating cylinder 3 rotate more stably, a fixing layer is provided at the lower end of the rotating cylinder 3. The fixing layer 6 has a hole of the same size as the outer wall of the rotating cylinder 3. A fixing mechanism 5 is provided on the fixing layer 6. The fixing mechanism 5 has a hole of the same size as the outer wall of the rotating cylinder 3. The lower end of the rotating cylinder 3 passes through the hole of the fixing layer 6. A receiving hopper 4 is provided on one side of the rotating cylinder 3.

[0027] Furthermore, the receiving hopper 4 is at least one of round tube, square tube or U-shape, with round tube preferred. When receiving material, the material received by the receiving hopper 4 will not overflow. The receiving hopper 4 is made of steel plate to improve hardness and service life.

[0028] To reduce the risk of breakage due to excessive resistance, the transmission mechanism 2 is composed of an insertion rod 211, a first connecting rod 221, and a second connecting rod 231. One end of the insertion rod 211 is detachably connected to the reducer 1, and the other end of the insertion rod 211 is fixed to one end 221 of the first connecting rod. The other end of the first connecting rod 221 is provided with a connecting flange 224, which has multiple internal connecting holes. Both ends of the second connecting rod 231 are respectively provided with fixing flanges 232, which have multiple internal connecting holes identical to those of the connecting flange 224. The connecting flange 224 of the first connecting rod 221 is detachably connected to the fixing flange 232 at one end of the second connecting rod 231 via a connecting screw 223. When the transmission mechanism 2 experiences excessive resistance during rotation, the fixing screw 223 between the connecting flange 224 at the other end of the first connecting rod 221 and the fixing flange 232 of the second connecting rod 231 will break first, thus protecting the insertion rod from breakage.

[0029] Furthermore, the transmission mechanism 2 is made of steel, which increases its hardness and service life.

[0030] To further strengthen the connection between the first connecting rod 221 and the second connecting rod 231, several connecting holes are provided on the connecting flange 224 and the fixed flange 232, preferably four connecting holes. Several connecting bolts 223 are used to fix the connecting flange 224 and the fixed flange 232, preferably four connecting bolts 223.

[0031] Furthermore, to improve the stability between the first connecting rod and the connecting flange 224, a reinforcing member is provided on the connecting flange 224.

[0032] Furthermore, to improve the stability between the second connecting rod 231 and the fixed flange 232, a reinforcing member is provided on the fixed flange 232.

[0033] Furthermore, the reinforcement is at least one of triangular, square, or arc-shaped, and is made of steel, and is welded to the connecting flange 224 or the fixing flange 232 to increase the fixing strength.

[0034] Furthermore, the rotating cylinder 3 is a hollow cylindrical structure with a flange seal welded to the top and an open bottom. The material collected by the receiving hopper 4 flows down into the rotating cylinder 3 and then into the collecting hopper below. The top of the rotating cylinder 3 is provided with a flange of the same size as the fixed flange at the other end of the second connecting rod 231. The flange at the top of the rotating cylinder 3 is detachably connected to the fixed flange 232 at the other end of the second connecting rod 231 by a screw. When the transmission mechanism is damaged, the transmission mechanism 2 can be repaired after the flange at the top of the rotating cylinder 3 and the fixed flange at the other end of the second connecting rod 231 are disassembled.

[0035] Furthermore, to make it easier to insert the insertion rod 211 into the reducer 1, a chamfer 213 is provided at the top of one end of the insertion rod 211; when the insertion rod 211 is inserted into the drive shaft mounting port of the reducer 1, a keyway 212 is provided on the insertion rod 211 to increase the stability of the reducer 1 and the insertion rod 211. When the locking piece in the drive shaft mounting port locks the keyway 212 of the insertion rod 211, the insertion rod 211 is more stable in the reducer 1 when the reducer 1 is rotating.

[0036] One end of the receiving hopper 4 is connected to the inlet on one side of the rotating drum 3. The receiving port at the other end of the receiving hopper 4 is inclined, making it easier to catch the sample material. The other end of the receiving hopper 4 is higher than one end of the receiving hopper 4. The two ends of the receiving hopper 4 form inclined surfaces. The inclination of the receiving hopper 4 allows the sample material to slide freely downwards and enter the collecting hopper below the rotating drum 3 through the inside of the rotating drum 3.

[0037] Since the receiving hopper 4 is only fixedly connected to the rotating cylinder 3 at one end, it will break downwards when the material received is too large. At this time, a load-bearing component is installed on the receiving hopper 4. The lower end of the load-bearing component is fixedly connected to the upper side of the receiving hopper 4, and the left end of the load-bearing component is fixedly connected to one side of the rotating cylinder 3, which increases the load-bearing capacity of the receiving hopper 4.

[0038] Furthermore, the load-bearing component is at least one of triangular, strip-shaped, or arc-shaped, with triangular load-bearing components made of metal being preferred as they have greater load-bearing capacity.

[0039] In order for the fixing mechanism 5 to be fixed on the fixing layer 6, a fixing hook 7 is provided inside the fixing layer 6. One end of the fixing hook 7 is located inside the fixing layer 6, and the other end of the fixing hook 7 protrudes from the fixing layer 6. The protruding part of the other end of the fixing hook 7 is provided with external threads. After the fixing mechanism 5 is fitted with the fixing hook 7, it can be tightened with a nut to fix it.

[0040] Furthermore, the fixing hook 7 is at least one of a single hook, multiple hooks, or L-shaped type that can provide stable resistance, and the fixing hook 7 is made of metal to increase the rigidity of the fixing hook 7.

[0041] The fixing mechanism 5 consists of a locking flange 51 and a locking clamp 52. The locking flange 51 is sleeved on the lower end of the rotating cylinder 3. The locking flange 51 has several fixing holes. The locking flange 51 is threadedly connected to the other end of the fixing hook 7 through the fixing holes, so that the rotating cylinder rotates more stably.

[0042] Furthermore, to prevent the rotating cylinder 3 from falling downwards and causing an accident when it is disassembled from the transmission mechanism 2 during maintenance, or to prevent the rotating cylinder 3 from needing to be supported from below, a locking clamp 52 is installed on the locking flange 51. The locking clamp 52 consists of a first clamp 521 and a second clamp 522. The first clamp 521 is fixedly installed on the locking flange 51. Both the first clamp 521 and the second clamp 522 are provided with mating screw holes. The second clamp 522 is detachably connected to the first clamp 521 by a screw. When the transmission mechanism 2 needs to be maintained or replaced due to damage, the locking clamp 52 can lock the rotating cylinder 3 around the outside of the rotating cylinder 3 by a screw, so it is no longer necessary to use ropes to suspend it or use something to support the rotating cylinder 3.

[0043] like Figure 1-3 As shown, in this embodiment, when the belt head drive shaft sampling machine is in operation, the reducer 1 is vertically installed on the fixed bracket. One end of the insertion rod 211 is inserted into the drive shaft port of the reducer 1, and the other end of the insertion rod 211 is fixed to one end of the first connecting rod 221. The connecting flange 224 on the other end of the first connecting rod 221 is detachably connected to the fixing flange 232 on one end of the second connecting rod 231 through the connecting screw 223. The fixing flange 232 on the other end of the second connecting rod 231 is connected to the flange screw at the top of the rotating cylinder 3. The lower end of the rotating cylinder 3 passes through the fixing layer 6. One end of the fixing hook 7 is located inside the fixing layer 6, and the other end of the fixing hook 7 protrudes above the fixing layer 6. The locking flange 51 is sleeved on the outer wall of the rotating cylinder 3 and fixed to the fixing layer 6 through the fixing hook 7. A receiving hopper 4 is provided on one side of the rotating cylinder 3. When the sampler is in normal operation, when the reducer 1 is powered on, the reducer 1 drives the transmission mechanism 2, the transmission mechanism 2 drives the rotating drum 3, and the rotating drum 3 drives the receiving hopper 4 to rotate 360° at the discharge port to receive material. It can collect all the material in the cross section of the entire material flow. Due to the inclination of the receiving hopper 4, the material slides freely down into the rotating drum 3 and flows into the collection hopper through the inside of the rotating drum 3.

[0044] When the rotation speed is high, the sampling amount of the receiving hopper 4 is too large, or the impact force of the material flow is large, the rotation resistance of the receiving hopper 4 will be greatly increased, which will cause the connecting screw 223 on the first connecting rod 221 and the second connecting rod 231 to break. At this time, the locking clamp 52 on the locking flange 51 is used to lock the rotating cylinder 3 completely through the screw, so that the rotating cylinder 3 will not fall down and cause an accident. After the broken connecting screw is removed and replaced with a new connecting screw, the reducer 1 can be started to operate the equipment. It is not necessary to remove the entire reducer to complete the replacement of the transmission mechanism 2. The operation is quick and does not affect the timeliness of the quality inspection of the incoming coke and the unloading efficiency.

[0045] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
