Technical Field
The invention belongs to grinding and crushing equipment for lumpy raw materials such as stones, ores and the like, and particularly relates to a double-rotor hammer type sand making machine with an adjusting device.
Background
At present, in the field of shaping of broken stones and sand making, the main types of sand making machines are a horizontal fine crusher, a counterattack crusher, a vertical shaft type impact sand making machine and the like. The horizontal fine crusher and the impact crusher are stone materials which are impacted and impacted due to the working principle, the particle shape of the product is poor and is mostly 'needle-shaped', the actual using effect is very poor, and the product cannot be applied to mortar or concrete. The vertical shaft type impact sand making machine adopts the principles of impact and grinding to make sand, and a finished product can meet the use requirement, but has a complex structure and high cost, so that the early investment cost of a user is greatly increased, and the use cost of the user is increased.
Disclosure of Invention
The invention aims at the technical task of providing a double-rotor hammer type sand making machine with an adjusting device aiming at the defects of the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a take adjusting device's birotor hammer type system sand machine, includes motor, frame, feed arrangement, broken chamber lid, pneumatic cylinder, main welt, first supplementary welt, second supplementary welt, adjustment lead screw, rotor, clean room and discharge gate, wherein broken chamber includes broken chamber in a left side and the broken chamber in the right side, wherein the discharge gate is located frame bottom intermediate position department, feed arrangement sets up the intermediate position department at the frame top, the clean room sets up the central point in the frame inside and puts, wherein broken chamber in a left side and the broken chamber in the right side set up in the frame inside and about feed arrangement and clean room symmetry, the rotor sets up in broken chamber in a left side and the broken intracavity in the right side and through motor drive.
Furthermore, one end of the main lining plate is movably fixed on the crushing cavity cover through a pin shaft, and the other end of the main lining plate is fixed at the bottom of the crushing cavity cover through an adjusting screw rod.
Further, the fixed top that sets up in the inside of broken chamber lid of first supplementary welt, the fixed both sides that set up at the clean room of second supplementary welt, and wherein set up the second of clean room both sides and assist the welt and be "eight" font.
Furthermore, the bottom of the crushing cavity cover is hinged with the frame, and the top of the crushing cavity cover is movably connected with a hydraulic cylinder arranged at the bottom of the frame.
Further, the rotor is provided with at least two groups of hammers along the radial direction.
Furthermore, a flue gas channel which is inclined downwards is arranged at the bottom of the dust removing chamber.
The beneficial effects of the invention are: building stones shunt to the left and right crushing cavities through the central feed inlet, under the action of high-speed rotating hammer head striking, the building stones are primarily crushed, then impact on the impact device to enable the materials to be secondarily crushed and rebound, high-speed friction between rebound building stones is shaped, and an adjusting device is arranged behind the impact device, the gap between the impact device and the hammer head can be adjusted, the purpose of compensating abrasion of the hammer head or adjusting product gradation is achieved, meanwhile, a building stone lining layer is formed below the crushing cavity, grinding and crushing between the building stones can be formed, and thus, through multiple times of impact continuous circulating crushing and grinding, the building stones are sufficiently crushed, and under the grinding action, the crushed product grains are good, mostly form a structure close to a cube, the content of needle-shaped grains is extremely small, and the product gradation is reasonable, and the requirement of machine-made sand can be met.
Because the whole structure of the equipment is simpler, the raw material and processing cost of the equipment is greatly reduced compared with that of a vertical shaft type impact sand making machine, and the use cost of a user is effectively saved.
The dust removal device can be connected with an external dust remover, so that the phenomenon that dust generated in the operation process of the sand making machine flies is eliminated, and the requirement of green environmental protection is met.
The hydraulic opening device can be opened when the worker inspects and maintains the equipment, the labor intensity of the worker is reduced, and the efficiency is greatly improved.

Detailed Description
The invention is described in detail below with reference to the drawings attached hereto:
as shown in fig. 1, 2 and 3, a take adjusting device's birotor hammer system sand machine, including motor 13, frame 1, feed arrangement 3, broken chamber 11, broken chamber lid 2, pneumatic cylinder 12, main welt 8, first supplementary welt 7, second supplementary welt 9, adjustment screw 6, rotor 5, clean room 4 and discharge gate 10, wherein broken chamber 11 includes broken chamber in a left side and the broken chamber in the right side, wherein discharge gate 10 is located frame 1 bottom intermediate position department, feed arrangement 3 sets up the intermediate position department at frame 1 top, clean room 4 sets up the central point in frame 1 inside, wherein broken chamber in a left side and the broken chamber setting in the frame 1 in the right side just are symmetrical about feed arrangement 3 and clean room 4, rotor 5 sets up in broken chamber in a left side and the broken intracavity in the right side and drives through motor 13.
Furthermore, one end of the main lining plate 8 is movably fixed on the crushing cavity cover 2 through a pin shaft, and the other end of the main lining plate is fixed at the bottom of the crushing cavity cover 2 through an adjusting screw rod 6.
Further, the fixed top that sets up in the inside of broken chamber lid 2 of first supplementary welt 7, the fixed both sides that set up at clean room 4 are assisted to the second welt 9, and wherein set up the second of 4 both sides in clean room and assist welt 9 and be "eight" font.
