Description

Construction waste crushing device

technical field

The invention relates to the field of building construction equipment, in particular to a construction waste crushing device.

Background technique

In the process of building construction, a large amount of construction waste is generated, mainly involving various cement board wastes, which need to be crushed by a crushing device and then transported. For the current construction waste crushers, hammer crushers are mainly used, which use continuously rotating crushing hammers to hit large building panels so that they are crushed and then discharged. However, the current crusher has the problem that after introducing large and small building materials into the crushing cavity, the position of the building materials is not processed, and the building materials are directly hit by the breaking hammer, so that the building materials are repeatedly ejected between the breaking hammer and the crushing plate. Breaking, in this process, the building materials are hit in the air without any fixed state, so that only a small amount of energy of the breaking hammer is transmitted to the building materials, resulting in a small crushing strength; in addition, a large number of blows have no vertical impact on the Therefore, the impact efficiency is very limited, and the loss of useless work is relatively large, resulting in serious waste of energy.

Contents of the invention

In view of the above problems, the object of the present invention is to provide a construction waste crushing device, which has high crushing strength and crushing efficiency, and has a good energy-saving effect.

The technical solution adopted by the present invention to solve the technical problem is: the construction waste crushing device includes a crushing chamber, the upper part of the crushing chamber is provided with a feeding port; the lower part of the crushing chamber is provided with a conical sieve with the cone facing upwards Stencil; the lower part of the sieve sieve is a discharge chamber; the sieve sieve is evenly distributed with strip-shaped relief holes in the circumferential direction; the lower part of the sieve sieve is evenly distributed with a breaker rotating in a vertical plane ; The sweeping surface of the breaking hammer extends above the strip-shaped relief hole; the screen mesh plate is driven by a stepping motor and rotates around its own conical axis; the stepping motor rotates around its own conical axis; Run once, rotate the previous strip-shaped relief hole on the screen material plate to the next strip-shaped relief hole; during the sleep period of the stepping motor, the breaker rotates continuously to hit the strip-shaped relief hole. The building material above the shaped give way hole.

Preferably, the feed port is further provided with a one-way door, the opening direction of which is from the outside to the inside of the crushing chamber, so as to prevent fragments in the crushing chamber from splashing out.

As a preference, the number of the strip-shaped relief holes is 2 to 3 times that of the breaking hammer, so that the building material waste at each position on the sieve screen can be hit by the breaking hammer, and at the same time it can use as little as possible. breaking hammer.

Preferably, the breaking hammer is directly driven by a motor; or is jointly coupled to a ring bevel gear through a bevel gear, and then the motor drives the ring bevel gear.

The beneficial effect of the present invention is that: when the construction waste crushing device is in operation, the construction waste is introduced into the crushing chamber from the feed port, since the screen mesh plate at the lower part of the crushing chamber is conical with the cone facing upwards, therefore, the construction board is Under the action of gravity, there will be a large space area spread on the conical surface, so that the breaking hammer can hit the building board nearly vertically, and the hitting efficiency is high; and, because the building board is placed on the screen material under the action of gravity When the stencil is hit by the breaking hammer, most of the impact energy of the breaking hammer is transmitted to the surface of the plate, so the energy utilization rate is high.

detailed description

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

In the embodiment shown in Fig. 1 and Fig. 2, the construction waste crushing device includes a crushing chamber 1, and the upper part of the crushing chamber 1 is provided with a feed port 10; a one-way door 11 is also provided at the feed port 10, Its opening direction is from the outside of the crushing chamber 1 to the inside, preventing fragments in the crushing chamber 1 from splashing out.

The lower part of the crushing chamber 1 is provided with a conical sieve screen 3 with the cone facing upwards; the lower part of the sieve screen 3 is the discharge chamber 2; Position holes 30; the bottom of the sieve mesh plate 3 is evenly distributed with breakers 4 rotating in a vertical plane; in this embodiment, the breakers 4 are driven by a breaker motor 41, and the sweeping surface of the breaker extends to Above the strip-shaped relief hole 30 . In this embodiment, 8 strip-shaped relief holes 30 are provided on the sieve net plate 3, and 4 breaking hammers are equipped, so that the larger building panels at various positions on the sieve net plate 3 can Covering on the strip-shaped relief holes, during the rotation process of the screen material mesh plate 3, each strip-shaped relief hole covered by the plate can always be rotated to the top of each breaking hammer 4.

The sieve mesh plate 3 is driven by the stepping motor 5 through the ring gear 31, and rotates around its own conical axis; A strip-shaped relief hole is rotated to the last strip-shaped relief hole, that is, the sieve mesh plate 3 is coincident with itself every time it turns an angle, which is an equivalent transformation in geometry; During the rest period of the stepping motor 5 , the breaking hammer 4 rotates continuously to hit the building materials above the strip-shaped relief hole 30 .

When the above-mentioned construction waste crushing device is in operation, the construction waste is introduced into the crushing chamber 1 from the feed port 10. Since the screen mesh plate 3 at the bottom of the crushing chamber 1 is conical with the cone facing upward, the building boards are crushed under the action of gravity. , there will be a larger space area evenly spread on the conical surface, so that the breaking hammer 4 can hit the building board nearly vertically, and the hitting efficiency is relatively high; and, because the building board is placed on the screen mesh plate under the action of gravity Therefore, most of the impact energy of the breaking hammer is transmitted to the surface of the plate, so the energy utilization rate is high.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
