Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyor heads, in particular to a scraper conveyor head. Background Art

[0002] The conveyor that uses a scraper chain to transport bulk materials in a trough is called a scraper conveyor. The main structure and components of a scraper conveyor are basically the same. It consists of three parts: the head, the middle part and the tail. The working principle of the scraper conveyor is to use the open chute as a bearing for coal, gangue or materials, and fix the scraper on the chain as a traction component. When the head transmission part is started, it drives the sprocket on the head shaft to rotate, so that the scraper chain circulates and drives the material to move along the chute until it is unloaded at the head.

[0003] At present, the machine head is generally installed on the machine head frame. However, a power unit is arranged on the machine head, which is composed of an electric motor, a hydraulic coupling, a reducer, a roller, a machine head sprocket and a chain. The power unit will vibrate during operation, which will drive the machine head frame below to vibrate. Currently, there is no buffer design on the machine head. At the same time, the power unit is directly exposed and easily damaged by external impact, and there is a lack of effective protection measures on the machine head. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a scraper conveyor head.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A scraper conveyor head comprises a head body, a power unit is arranged on the head body, fixing plates are symmetrically arranged on the side wings of the head body, two groups of shock absorbers are symmetrically arranged on the fixing plates and the side wings of the head body, one end of the shock absorber is connected to a connecting plate for connecting to the head frame, a protective box is movably arranged on the head body, which is located outside the power unit and spaced apart from the shock absorber, a mounting hole for connecting a reducer to a drum is opened on the protective box, and a maintenance door is rotatably connected to the protective box.

[0007] This device can effectively buffer the vibration of the power unit during operation and thus reduce the impact on the head frame. At the same time, the power unit is effectively protected and is not prone to failure due to external impact. The safety and functionality of the head are further expanded and optimized.

[0008] Furthermore, a sound insulation board is arranged in the protection box.

[0009] The above solution can effectively reduce the noise generated when the power unit is in operation through the sound insulation board.

[0010] Furthermore, the maintenance door is provided with heat dissipation holes.

[0011] Furthermore, a waterproof and breathable membrane is provided on the heat dissipation hole.

[0013] Furthermore, mounting frames are mounted on both side wings of the machine head body, and sensors for real-time monitoring of the amount of material attached to the scraper are arranged on the mounting frames.

[0014] Furthermore, a visual sensor is arranged on the mounting frame, a buzzer is arranged on the machine head body, and the buzzer and the visual sensor are electrically connected.

[0015] In the above scheme, when the visual sensor detects that the content of material attached to the scraper is too much, it will feedback a signal to the controller, and then the controller will control the buzzer to sound and the scraper conveyor will stop working to remind the staff to come and clean it immediately.

[0016] Furthermore, the protection box is welded with high-strength alloy plates and a wear-resistant layer is welded on the surface of the protection box.

[0017] The protective box in the above solution has good overall impact resistance and wear resistance and a long service life.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] Compared with the existing technology, this device can effectively buffer the vibration of the power unit during operation and thus reduce the impact on the head frame. At the same time, the power unit is effectively protected and is not prone to failure due to external impact. The safety and functionality of the head are further expanded and optimized.

[0025] 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. The utility model is further described in combination with the drawings and embodiments:

[0026] like Figures 1 to 3 As shown, a scraper conveyor head includes a head body 1, on which a power unit is arranged, which is not shown in the figure. Fixed plates 11 are symmetrically arranged on the side wings of the head body 1, and two groups of shock absorbers 12 are symmetrically arranged on the fixed plates 11 and the side wings of the head body 1. One end of the shock absorber 12 is connected with a connecting plate 13 for connecting to a head frame, which is not shown in the figure. A protective box 2 is movably arranged on the head body 1, which is located on the outside of the power unit and spaced apart from the shock absorber 12. A mounting hole 201 for connecting the reducer and the drum is opened on the protective box 2, and a maintenance door 22 is rotatably connected to the protective box 2.

[0027] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, mounting frames 3 are mounted on both side wings of the head body 1, and sensors for real-time monitoring of the amount of material attached to the scraper are arranged on the mounting frames 3. Specifically, a visual sensor 31 is arranged on the mounting frame 3, and a buzzer 32 is arranged on the head body 1. The buzzer 32, the visual sensor 31 and the motor are all electrically connected to the controller, which is not shown in the figure. When the visual sensor 31 detects that the amount of material attached to the scraper is too much, it will feedback a signal to the controller, and then the controller will control the buzzer 32 to sound and the scraper conveyor will stop working to remind the staff to come and clean it immediately.

[0028] The visual sensor 31 set at the unloading end of the machine head can be used to visually monitor the material content attached to the scraper in real time. As the scraper conveyor runs for a long time, the amount of material attached to the scraper will increase. Several images are transmitted in advance in the visual sensor. The images record the state of the scraper under different stockpiling states in sequence. When the state of the scraper is closest to the number of frames matching the image with the most accumulated material, the visual sensor 31 transmits a signal to the controller, and then the controller immediately controls the buzzer 32 to sound to remind the staff to quickly come to clean the scraper. It should be noted that the position detected by the visual sensor 31 is on one side of the unloading port at the machine head end. At this time, the material left from the unloading port naturally does not interfere with it and can be automatically removed. It only monitors the material attached to the scraper in real time. When the visual sensor 31 feeds back a signal to the controller, the controller automatically controls the motor in the power unit to stop. It does not need to be manually shut down. It can be put into use again after waiting for the staff to clean it. The specific cleaning method is brush cleaning, which can effectively reduce the wear of the scraper groove during the operation of the scraper, and the subsequent material conveying effect is stable.

[0029] In other embodiments, the sensor may also be a laser radar sensor; the laser radar sensor can also detect the pile status on the scraper in real time, and its principle will not be described.

[0030] In a further refinement of the embodiment of the utility model, the protection box 2 is welded with high-strength alloy plates and a wear-resistant layer is welded on the surface of the protection box 2; the protection box 2 has good overall impact resistance and wear resistance and a long service life.

[0031] The workflow of this utility model:

[0032] First, hoist the head body 1 to the top of the head frame, and then use a number of bolts to cooperate with the connecting plate 13 to achieve a stable connection between the head body 1 and the head frame. When the scraper conveyor is installed, the power unit is immediately started to start material transportation. After the power unit is turned on, vibration will occur. At this time, the shock absorber 12 can effectively buffer and reduce the vibration degree to ensure the stability of the head frame support;

[0033] At the same time, by installing the protection box 2 on the outside of the power unit, the probability of damage to the power unit when it is impacted by the outside can be effectively reduced. The protection box 2 has good impact resistance and wear resistance, and has a long service life. At the same time, by opening and closing the maintenance door 22, it is convenient to maintain and repair the internal power unit parts;

[0034] Compared with the existing technology, this device can effectively buffer the vibration of the power unit during operation and thus reduce the impact on the head frame. At the same time, the power unit is effectively protected and is not prone to failure due to external impact. The safety and functionality of the head are further expanded and optimized.

[0035] In some embodiments, Figure 2 As shown, a sound insulation board 21 is arranged in the protection box 2; this embodiment can effectively reduce the noise generated when the power unit is operating through the sound insulation board 21.

[0036] In other embodiments, Figure 3 As shown, a heat dissipation hole 23 is opened on the maintenance door 22 and a waterproof breathable membrane is arranged on the heat dissipation hole 23; this embodiment can realize air circulation between the protection box 2 and the external environment through the heat dissipation hole 23, so that the heat generated when the power unit is in operation can be effectively discharged, and the waterproof breathable membrane can prevent external rainwater from penetrating into the protection box 2, thereby further extending the service life of the power unit.
