Description

Technical Field

[0001] This utility model belongs to the technical field of screening machines, and in particular relates to a tracked environmentally friendly screening machine. Background Technology

[0002] The tracked environmentally friendly screening machine is a material separation device that combines high mobility with green environmental protection attributes. With a tracked chassis as its core support, it breaks through the dependence of traditional fixed screening equipment on the site and can flexibly adapt to complex working conditions such as mines, construction solid waste sites, river dredging areas, and road construction sites. It can be quickly positioned and operated without the need for complicated foundation construction. It is equipped with a sealed screening chamber, a pulse dust removal system, and low-noise drive components, which can effectively control dust emission and operating noise, strictly comply with environmental emission standards, and avoid pollution to the surrounding environment.

[0003] However, it still has the following drawbacks in actual use: When the tracked environmental protection screening machine is in operation, although the vibration of the screening component is a necessary condition for material separation, the vibration and shaking during screening will have a significant adverse effect on several key components other than the screening component. First, it affects the tracked chassis system. As the core of equipment support and movement, continuous shaking will cause uneven force on the track and ground, accelerated wear of the track plates, fatigue and deformation of the tension springs, and easy loosening of the pins and bolts connecting the chassis frame and the track. Second, it affects the environmental protection auxiliary system. The outer sealing strip of the sealed screening chamber will age and break faster due to repeated squeezing and stretching caused by shaking, resulting in dust leakage from the gaps and destroying the environmental protection effect. The pipe interface and dust hood of the pulse dust removal system will also become loose due to shaking. Furthermore, it interferes with intelligent control and electrical components. The vibration sensor and material flow sensor on the equipment need stable operating conditions. Shaking will cause frequent fluctuations in the sensor detection data, causing the controller to misjudge and other situations. Utility Model Content

[0004] The purpose of this utility model is to provide a tracked environmentally friendly screening machine. Through the setting of the support components, this utility model greatly reduces a series of problems caused by the vibration of the traditional tracked environmentally friendly screening machine during screening.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a tracked environmentally friendly screening machine, including a main body component and a support component. The main body component includes a tracked chassis, a vibrating screen body is provided on the upper surface of the tracked chassis, a belt conveyor is provided on the upper surface of the vibrating screen body, and a belt conveyor is provided on the side of the vibrating screen body. The support assembly includes a fixed plate that is horizontally fixed to the side of the vibrating screen body. A threaded rod is rotatably connected to the center of the lower surface of the fixed plate. A motor is fixed to the center of the upper surface of the fixed plate. The motor drive shaft passes through the fixed plate and is fixedly connected to the threaded rod. A connector is threaded on the outer periphery of the threaded rod. A spring damper is fixed on the connector. A connecting shaft is fixed at the end of the spring damper away from the connector, and the connecting shaft is movably connected to the connector. A universal ball is provided at the end of the connecting shaft away from the spring damper, and a base is fixed on the outer surface of the universal ball.

[0006] Furthermore, multiple belt conveyors are provided, the main body of the vibrating screen is a multi-stage vibrating screen, and the inlet end of each belt conveyor is connected to the outlet end of each stage of the vibrating screen main body.

[0007] Furthermore, the support assembly also includes a limiting rod that is fixed parallel to the side of the vibrating screen body, and a connecting piece that is movably connected to the outer periphery of the limiting rod.

[0008] Furthermore, the base includes a base plate that is fixedly connected to the omnidirectional ball, and multiple conical members are arrayed at the end of the base plate away from the omnidirectional ball.

[0009] Furthermore, a support spring is fixed to the opposite surface of the connecting shaft and the base plate.

[0010] Furthermore, four sets of support components are provided, and each set is located at one of the four corners of the vibrating screen body.

[0011] This utility model has the following beneficial effects: 1. This utility model, through its set support components, allows the motor to rotate the threaded rod during use, causing the connecting parts to move downwards until the conical part of the base inserts into the ground, thus lifting the tracked chassis off the ground and preventing displacement. During the screening operation, the vibration generated by the vibrating screen body is transmitted to the support components. The spring damper will preferentially absorb most of the vibration energy, while the support spring will assist in buffering the remaining vibration. The two work together to significantly reduce the vibration transmitted to the tracked chassis, greatly reducing a series of problems caused by the vibration of the traditional tracked environmentally friendly screening machine during screening.

[0012] 2. With the support components set up in this utility model, when the support component base supports the ground, the universal ball will automatically adjust the base angle according to the ground tilt angle to ensure that the base plate is in full contact with the ground. After the conical part is inserted into the ground, it further improves the overall stability of the equipment and solves the problem that it is not easy to support the inclined ground.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-5 As shown, this utility model is a tracked environmentally friendly screening machine, including a main component 1 and a support component 2. The main component 1 includes a tracked chassis 11, a vibrating screen body 12 is provided on the upper surface of the tracked chassis 11, a belt conveyor 13 is provided on the upper surface of the vibrating screen body 12, and a belt conveyor 14 is provided on the side of the vibrating screen body 12. The tracked chassis 11 is the moving and basic support component of the equipment, which can flexibly adapt to complex working conditions such as mines, construction solid waste sites, and river dredging areas. It can move the equipment to the working position without building a complex foundation. At the same time, when the support component 2 is not in use, it temporarily bears the weight of the entire equipment. The vibrating screen body 12 is the core screening component of the equipment. It adopts a multi-stage design and can classify and separate the input materials. Through its own vibration, it screens the materials into different grades according to particle size and other specifications, meeting diverse material screening needs.

[0017] Belt conveyor 13 is installed on the upper surface of the vibrating screen body 12 to transport the raw material to be screened smoothly into the vibrating screen body 12, providing a continuous material supply for the screening operation. Belt conveyor 14 is provided with multiple belts, each corresponding to a different stage of the vibrating screen body 12. Its inlet end is connected to each stage of the vibrating screen body 12's outlet end, which can transport materials of different grades after screening by the vibrating screen body 12 to designated collection areas, avoiding mixing of materials of different specifications.

[0018] The support assembly 2 includes a fixed plate 21 horizontally fixed to the side of the vibrating screen body 12. A threaded rod 22 is rotatably connected to the center of the lower surface of the fixed plate 21. A motor 23 is fixed to the center of the upper surface of the fixed plate 21. The power shaft of the motor 23 passes through the fixed plate 21 and is fixedly connected to the threaded rod 22. A connector 24 is threaded to the outer periphery of the threaded rod 22. A spring damper 25 is fixed on the connector 24. A connecting shaft 26 is fixed to the end of the spring damper 25 away from the connector 24, and the connecting shaft 26 is movably connected to the connector 24. A universal ball 27 is provided at the end of the connecting shaft 26 away from the spring damper 25. A base 28 is also fixed to the outer surface of the universal ball 27.

[0019] The fixed plate 21 serves as the mounting base for the support assembly 2, supporting components such as the motor 23 and threaded rod 22. This ensures that all parts of the support assembly 2 can be stably assembled and linked with the vibrating screen body 12. The motor 23 is the power source for the support assembly 2, with its power shaft passing through the fixed plate 21 and fixedly connected to the threaded rod 22. After starting, it can drive the threaded rod 22 to rotate, providing power for the height adjustment of the support assembly 2. The threaded rod 22 is threadedly connected to the connecting piece 24. When it rotates under the drive of the motor 23, it can drive the connecting piece 24 to move up and down along its axis, thereby realizing the overall height adjustment of the support assembly 2 to adapt to the ground height and equipment support requirements of different work sites. The connecting piece 24 is connected to the threaded rod 22, the limiting rod 221, and the spring damper 25 respectively. It is both the receiving component for the power transmission of the threaded rod 22 and the mounting carrier for the spring damper 25. When the threaded rod 22 rotates, it is restricted by the limiting rod 221 and will not rotate synchronously with the threaded rod 22, but can only move smoothly up and down along the direction of the limiting rod 221.

[0020] One end of the spring damper 25 is fixed to the connector 24, and the other end is connected to the connecting shaft 26. Its core function is to absorb the vibration energy generated by the vibrating screen body 12 during operation, reduce the transmission of vibration to the tracked chassis 11, environmental auxiliary systems (such as sealing strips of the screening chamber and dust removal pipe interfaces), and electrical components (such as vibration sensors and flow sensors), and avoid damage to related components or interference with their functions due to vibration. The connecting shaft 26 connects the spring damper 25 and the universal ball 27, which not only transmits the supporting force, but can also be movably connected to the connector 24. It can cooperate with the slight shaking of the vibrating screen body 12 and the angle adjustment of the universal ball 27 to flexibly adapt to the vibration of the equipment and the tilt of the ground. The universal ball 27 is connected between the connecting shaft 26 and the base 28 and can be freely adjusted in angle so that the base 28 can adapt to the tilt of the working site ground, ensuring that the base 28 always maintains good contact with the ground and improving the support stability.

[0021] The base 28 consists of a base plate 281 and a conical component 282, which can increase the contact area between the equipment and the ground and improve the support reliability. The conical component 282 is arranged in an array at the end of the base plate 281 away from the universal ball 27. It can be inserted into the ground during operation to enhance the grip of the base 28 and prevent the equipment from shifting during the vibrating screening process.

[0022] Furthermore, multiple belt conveyors 14 are provided, and the vibrating screen body 12 is a multi-stage vibrating screen. The inlet end of each belt conveyor 14 is connected to the outlet end of each stage of the vibrating screen body 12. Multiple belt conveyors 14 are provided, corresponding one-to-one with the multi-stage outlets of the vibrating screen body 12. Their inlet ends are connected to the outlet ends of each stage of the vibrating screen body 12, which can transport materials of different grades after screening by the vibrating screen body 12 to designated collection areas, avoiding the mixing of materials of different specifications.

[0023] Furthermore, the support assembly 2 also includes a limiting rod 221 fixed parallel to the side of the vibrating screen body 12, and a connecting piece 24 movably connected to the outer periphery of the limiting rod 221. The limiting rod 221 is fixed parallel to the side of the vibrating screen body 12 and works in conjunction with the threaded rod 22. Its outer periphery is movably connected to the connecting piece 24, which can limit the movement trajectory of the connecting piece 24, prevent the connecting piece 24 from shifting or rotating due to the rotation of the threaded rod 22, and ensure the stability of the up and down movement of the connecting piece 24.

[0024] Furthermore, the base 28 includes a base plate 281 fixedly connected to the universal ball 27. A plurality of conical members 282 are arranged in an array at the end of the base plate 281 away from the universal ball 27. The conical members 282 are arranged in an array at the end of the base plate 281 away from the universal ball 27. They can be inserted into the ground during operation to enhance the grip of the base 28 and prevent the equipment from shifting during the vibrating screening process.

[0025] Furthermore, a support spring 29 is fixed to the opposite surface of the connecting shaft 26 and the base plate 281. The support spring 29 is fixed between the opposite surface of the connecting shaft 26 and the base plate 281, and the auxiliary spring damper 25 further buffers the vibration of the vibrating screen body 12, while providing elastic support for the base 28, which can adapt to the slight undulations of the ground and ensure the tightness of the contact between the base 28 and the ground.

[0026] Furthermore, the support components 2 are provided in four sets, and are respectively located at the four corners of the vibrating screen body 12. This arrangement can stably support the entire device and reduce the shaking of the entire device during use.

[0027] The specific working principle of this utility model is as follows: When using this device, the tracked chassis 11 is used to move the equipment to the working area such as the mine or construction solid waste treatment site. Since the tracked chassis 11 is adapted to complex working conditions, there is no need to build a foundation in advance. It can stop directly at the target working point and complete the initial positioning.

[0028] After the rear support assembly 2 is adjusted and fixed, the motor 23 of the support assembly 2 is started. The motor 23 drives the threaded rod 22 to rotate. The connecting piece 24, which is threaded to the threaded rod 22, moves smoothly downward along the direction of the limit rod 221 under the restriction of the limit rod 221 until the conical piece 282 of the base 28 inserts into the ground, so that the track chassis 11 is removed from the ground to avoid damage to the track due to vibration during subsequent screening operations. During this period, the universal ball 27 will automatically adjust the angle of the base 28 according to the ground tilt angle to ensure that the base plate 281 is in full contact with the ground. After the conical piece 282 is inserted into the ground, it further improves the overall stability of the equipment and prevents displacement.

[0029] The material to be screened (such as ore, construction waste, etc.) is then fed into belt conveyor 13. After belt conveyor 13 starts, the material is conveyed at a uniform speed into the vibrating screen body 12. The vibrating screen body 12 starts and performs multi-stage screening. Through vibration, the material is separated into different grades according to particle size and other specifications. The material of each grade will be discharged from the corresponding outlet of the vibrating screen body 12 and directly enter the belt conveyor 14 connected to it. Multiple belt conveyors 14 start simultaneously and convey the screened material of different grades to the designated collection area (such as different material piles) to achieve graded collection of materials.

[0030] During the entire screening process, the vibration generated by the vibrating screen body 12 is transmitted to the support component 2. At this time, the spring damper 25 will absorb most of the vibration energy first, and the support spring 29 will assist in buffering the remaining vibration. The two work together to greatly reduce the transmission of vibration to components such as the track chassis 11, the sealing strip of the sealed screening chamber, the dust removal pipe interface, vibration sensor, and flow sensor. This avoids problems such as accelerated wear of the track plates, aging and damage of the sealing strip, loosening of the dust removal pipe, and fluctuations in sensor detection data, ensuring the environmental performance of the equipment and the stability of the electrical components until the single screening operation is completed. After the operation is completed, the motor 23 is started in reverse, causing the connecting piece 24 to drive the base 28 to move upward, the conical piece 282 to leave the ground, and then the equipment is moved to the next work point or storage area through the track chassis 11.

[0031] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
