Technical Field
[0001] The utility model relates to the technical field of mining machinery, in particular to a split type combined feeding device. Background Art
[0002] In feeding machinery involved in hydropower, mining, aggregates, etc., it is usually necessary to design a grate part at the front of the feeder to screen out fine materials and reduce the burden on the subsequent crusher.
[0003] In the traditional structure, the feeding equipment includes a feeder and a grate structure arranged in front of the feeder. The vibration motor is installed at the bottom of the entire feeding mechanism. During the feeding and conveying process, the vibration motor vibrates, driving the entire feeder to vibrate, completing the power drive for feeding.
[0004] Under this structure, the conveying part of the feeder and the screening part of the grate vibrate together. However, the vibration of the feeder changes dynamically. When the vibration frequency of the feeder decreases, the vibration frequency of the grate area decreases synchronously, resulting in a decrease in the screening frequency of the material and causing material jamming.
[0005] The essential problem is that the vibration conveying and screening processes of materials require different vibration working conditions, and often require different vibration frequency requirements. Therefore, it is necessary to improve the traditional feeding equipment to solve the problem that the feeder and the grate part are difficult to work in the optimal working conditions respectively. Utility Model Content
[0006] The purpose of the utility model is to address the deficiencies of the existing technology and thus provide a split combined feeding device in which a feeding conveying mechanism and a grate screening mechanism are separately arranged and driven separately, and both can achieve optimal working conditions without interfering with each other.
[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a split type combined feeding device, including a feeding conveying mechanism and a grate screening mechanism;

[0009] The feeding and conveying mechanism includes a conveying bracket, a conveying flat slide and a first vibration motor, wherein the first vibration motor is mounted on the conveying bracket and is used to drive the conveying flat slide to vibrate based on the conveying bracket;
[0010] The grate screening mechanism includes a screening support, a grate structure and a second vibration motor. The second vibration motor is installed on the screening support and is used to drive the grate structure to vibrate based on the screening support.
[0011] Preferably, the input side of the grating structure is arranged below the end of the conveying platform slide, and the grating structure and the conveying platform slide are partially overlapped.
[0012] Preferably, the conveying bracket includes a frame and shock-absorbing legs, the shock-absorbing legs are arranged around the frame, and the first vibration motor is symmetrically installed on both sides of the frame.

[0014] Preferably, the trough-type bracket is a bracket with trough edges on both sides and a trough body formed in the middle, and a grate structure arranged along the conveying direction is installed in the trough-type bracket.
[0015] Preferably, the grate structure is provided with at least two sections, and the grate located at the front side in the conveying direction is located below the grate at the rear side to form a grate structure that falls layer by layer.
[0016] Preferably, the rear end of the grating structure or the trough-type support overlaps the front end of the delivery support.

The working frequency setting of the vibration conveying and the working frequency setting of the grate screening can be the same or different. The two do not affect each other and will not cause insufficient screening frequency due to the decrease in conveying frequency, resulting in material jamming.
[0022] Both include brackets and vibration motors, and the external frame remains consistent. During the installation and assembly process, they can be applied to the same installation conditions as traditional feeders, avoiding the limited application compatibility due to the split design.
[0023] Furthermore, the shock-absorbing legs of the external brackets of the two are installed at the same height, the purpose of which is to adapt to the installation height requirements of the traditional integrated feeder, and the adaptability meets the requirements.

[0027] The technical solution of the present utility model is further described in detail below through specific implementation methods.
[0028] like Figure 1 As shown, a split combined feeding device includes a feeding conveying mechanism 1 and a grate screening mechanism 2.
[0029] The feeding and conveying mechanism 1 and the grate screening mechanism 2 are separately provided, and the grate screening mechanism 2 is provided on the output side of the feeding and conveying mechanism 1 .
[0030] The feeding and conveying mechanism 1 includes a conveying bracket 11, a conveying flat slide 12 and a first vibration motor 13. The first vibration motor 13 is installed on the conveying bracket 11 and is used to drive the conveying flat slide 12 to vibrate based on the conveying bracket 11. In this embodiment, the conveying bracket 11 includes a frame 112 and shock-absorbing legs 111. Shock-absorbing legs 111 are arranged around the frame 112. The first vibration motor 13 is symmetrically installed on both sides of the frame 111.
[0031] The grate screening mechanism 2 includes a screening bracket 21, a grate structure 22 and a second vibration motor 23. The second vibration motor 23 is installed on the screening bracket 21 and is used to drive the grate structure 22 to vibrate based on the screening bracket 21. In this embodiment, the screening bracket 21 includes a trough bracket 211 and shock-absorbing legs 212. The shock-absorbing legs 212 are installed at the four external corners of the trough bracket 211. The second vibration motor 23 is symmetrically installed on both sides of the trough bracket 211. The trough bracket 211 is a bracket with groove edges on both sides and a trough body formed in the middle. The trough bracket 211 is installed with a grate structure arranged along the conveying direction.
[0032] The first vibration motor and the second vibration motor both have oblique vibration directions and the same vibration direction.
[0033] As a whole, the feeding conveying mechanism and the grate screening mechanism are arranged to be inclined from top to bottom along the conveying direction, which is consistent with the material transmission direction.
[0034] Specifically, the input side of the grate structure 22 is arranged below the end of the conveying platform slide 12, and the grate structure 22 is partially overlapped with the conveying platform slide 12 to ensure that the material can smoothly enter the grate structure 22 from the conveying platform slide 12.
[0035] Generally speaking, the vibration directions of the first vibration motor and the second vibration motor are both oblique.
[0036] The assembly heights of the shock-absorbing legs of the feeding conveying mechanism and the grate screening mechanism are the same. This design method is mainly to ensure that the installation base height of the conveying mechanism and the grate screening structure is consistent with the installation base height of the traditional integrated feeder. It can be directly adapted to the traditional feeder installation environment and reduce the cost of investment in transformation.
[0037] In a preferred embodiment, the grating structure is provided with at least two sections, and the grating located at the front side in the conveying direction is located below the grating at the rear side to form a grating structure that falls layer by layer.
[0038] In a preferred embodiment, the rear end of the grate structure or the trough-type bracket overlaps with the front end of the conveying bracket, and the overlapping structure can transmit a part of the vibration energy. In particular, since the grate structure is located below, it can transmit the vibration energy to the conveying area, thereby improving the utilization efficiency of the vibration energy.
[0039] Technical principle description:
[0040] This split structure is installed in the original environment according to the traditional integrated structure. The first vibration motor and the second vibration motor are driven separately. The feeding and conveying mechanism maintains its own feeding speed for vibration driving, and the grate screening mechanism maintains its own screening frequency for vibration driving. The two do not affect each other and can both work under the best working conditions.
[0041] Finally, it should be noted that: The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
