Description
Technical Field
The invention relates to a floating crushing single tower. Belongs to the technical field of material crushing integrated systems.
Background
The crushing operation is not completed by one single machine at one time but by multi-machine multi-section crushing. In addition, auxiliary machines such as a feeding machine, a conveyor and a screening machine (also called a vibrating screen) are required to be matched, raw materials are conveyed to a first-stage material crusher by the feeding machine, after first crushing is carried out, products which are initially broken are conveyed to a second-stage material crusher by the conveyor to be crushed again, then the products are conveyed to a third-stage crushing machine, a fourth-stage crushing machine and the like, finally the products are conveyed to the screening machine by the conveyor to be screened, qualified finished products are classified and stored in a warehouse, unqualified products are conveyed to the material crusher by the conveyor to be crushed again, and the process is repeated, so that a crushing production line is formed. The crushing production line is widely applied to the field of building materials and the field of mining of mine resources.
The crushing production line in the prior art is an expanded mesh crushing production line mode and is divided into a plurality of sections for crushing, the two sections of crushing are connected by a linear conveyer belt of 25-35 meters, the occupied area is large, and the management is inconvenient; environmental pollution such as dust, sewage and noise is difficult to be radically treated; because the hidden danger of safety is difficult to be radically treated after production workers are in the crushing production line.
In the prior art, crushing production lines are divided into two major categories, namely "fixed" and "mobile":
the fixed type crushing production line has the advantages that 1, the equipment installation is not limited by the length, the width and the high space, and the large-scale crushing production line is not limited; 2. the material conveying is freely unfolded, and is very convenient; 3. the maintenance space is sufficient; the disadvantage is that 1, once the construction of the crushing production line is completed, the crushing production line cannot move; 2. the occupied area is large; 3. the soil is invaded;
the 'movable' has the advantages that 1, the operation can be moved in different places; 2. the soil is not invaded; 3. the installation is carried out again after the relocation, and the infrastructure cost is not required to be invested again; the device has the disadvantages that 1, the device is limited by the length, width, height and space of road transportation conditions and is only suitable for miniature and small crushing production lines; 2. the material conveying mechanism is complex and has high manufacturing cost; 3. the maintenance space is narrow, which makes the maintenance extremely inconvenient.
In addition, most of crushing production lines in the prior art are open-air production lines, during crushing operation, a crushing machine vibrates sharply to generate a large amount of acting force and concentrated stress on a supporting frame for supporting the crushing machine, the service life of the supporting frame is not long generally, a certain amount of damage can be generated on the ground of a material crushing site, soil resources are invaded, and some manufacturers can embed the supporting frame in a reinforced concrete foundation and the ground through a cast-in-place concrete foundation, but the problems can also exist. The feeder is an indispensable auxiliary device in the crushing production line, and the feeder feeds the raw materials into the crusher at the beginning of the production line for crushing operation; the feed face of feeding machine comprises the grating usually, in the feed, also have the screening function, a mud separation away for on the mineral aggregate, because earth gets into broken production line, can influence crushing effect, cause the breaker to block up, and influence the quality of finished product material, current mud feeding machine that removes adopts the grating to constitute a feed transport face more, grating parallel arrangement, the interval is the same, this structure causes the mineral aggregate to block up in the clearance of grating in carrying easily, can't advance or whereabouts, and obstruct the follow mineral aggregate to advance, cause the mineral aggregate of feed transport face to pile up, unable normal efficient carries out the feed.
In summary, in order to solve the problems in the prior art, it is urgently needed to invent a floating type crushing single tower which is centrally arranged with a plurality of material crushing devices, realizes that the material crushing devices are in a floating state, and realizes primary material screening when feeding is started. The whole single tower is strong in practicability, suitable for a material crushing site with high requirements for land resource protection, and capable of improving material crushing efficiency.

the feeding screening machine is connected with a plurality of material crushing devices through different material conveying pipelines.
The bearing structure is a concrete block or a reinforced concrete block or a sleeper or a steel bar, and the stone shock absorption layer is made of hard stones with the thickness of 20-500 mm.
The bottom end of the bearing structure is provided with a fine adjustment structure, and the fine adjustment structure is a hydraulic jack.
The single-tower frame comprises a transverse support frame and a vertical support frame, wherein the transverse support frame is used for placing material crushing equipment, material feeding equipment, material screening equipment and material conveying equipment, and the vertical support frame is used for supporting the transverse support frame.
The feeding screening machine comprises a vibration box body and an excitation device used for driving the vibration box body to vibrate, the vibration box body is of a hollow structure, the upper end face of the vibration box body is a feeding conveying face, one end of the feeding conveying face is a feeding end, the other corresponding end of the feeding conveying face is a discharging end, the feeding conveying face comprises a plurality of conveying faces, the conveying faces are continuously butted along a material advancing route, are sequentially arranged from high to low and are in a step shape, the conveying faces are formed by a plurality of screen bars and are provided with screening gaps, the length direction of the screen bars is consistent with the advancing direction of materials, the width of the screen bars is gradually reduced along the material advancing direction, and the screening gaps formed by the screen bars of the same conveying face are gradually increased along the material advancing direction.
The feeding and screening machine works by applying the vibration principle of a vibration exciter, in the vibration conveying process, soil attached to mineral aggregate is impacted with a feeding conveying surface due to vibration to fall off and be separated, then the soil is screened out through gaps among screen bars, the screen bars are designed into shapes with the width gradually reduced along the advancing direction of the mineral aggregate, the screening gaps can be gradually increased along the advancing direction of the mineral aggregate, thereby effectively preventing the mineral aggregate from being blocked, in order to prevent the screening gaps at the discharge end from being too large to meet the mud-removing screening requirement, the feeding conveying surface is decomposed into a plurality of conveying surfaces, the plurality of conveying surfaces are continuously butted along the advancing path of the mineral aggregate, the conveying surfaces are sequentially arranged in a step shape from high to low, then the screening gaps of each conveying surface are gradually increased along the advancing direction of the mineral aggregate, the mineral aggregate can be overturned through drop and vibration, and thereby achieving good mud-removing screening effect, but also avoids mineral aggregate from being blocked between the screen bars.
