Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and in particular relates to a raw material mixing device for plant nanofiber reinforced concrete slabs. Background Art

[0002] Plant nanofiber reinforced concrete board is a concrete board made by adding plant nanofibers into concrete, which can enhance the tensile strength and compressive strength of the concrete board, improve the durability of the concrete and improve the crack resistance, etc. The concrete board is made by adding plant nanofibers to the concrete raw materials when mixing plant nanofibers with concrete, and then mixing them through a mixer. The plant nanofibers are mixed with the concrete raw materials to make a concrete board.

[0003] When the existing plant nanofiber reinforced concrete slab raw material mixing device is used, the plant nanofiber and the concrete raw material are put into the mixing drum of the mixer, and then the rotating mixing shaft drives the mixing blades to rotate to mix and stir the raw materials. However, when the raw materials in the mixing drum are too full for mixing, some concrete raw materials in the mixing drum are easily overflowed from the top of the mixing drum under the rotating stirring action of the mixing blades, resulting in waste of concrete, and the overflowed concrete is easy to adhere to the outer wall of the mixing drum, which is difficult to clean after drying and solidifying. For this reason, we propose a plant nanofiber reinforced concrete slab raw material mixing device. Utility Model Content

[0004] The purpose of the utility model is to provide a plant nanofiber reinforced concrete slab raw material mixing device to solve the problem that when the existing plant nanofiber reinforced concrete slab raw material mixing device is in use, when the raw materials in the mixing drum are overfilled for mixing, some concrete raw materials in the mixing drum are easily overflowed from the top of the mixing drum under the rotating stirring action of the stirring blades, resulting in waste of concrete slurry.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plant nanofiber reinforced concrete slab raw material mixing device, comprising a mixing drum, a mixing shaft and two groups of mixing blades installed on the top of the mixing shaft, a protective mechanism is arranged on the top of the mixing drum, the protective mechanism comprises a protective member and two groups of locking members, the protective member comprises a protective ring, a rubber ring is fixedly arranged on the bottom of the protective ring, the protective ring is located above the mixing drum, an annular groove is opened on the bottom of the rubber ring, and the top of the mixing drum penetrates into the interior of the annular groove.

[0006] Preferably, the locking member comprises a side block and an inclined plate, a through slot is formed inside the side block, and the bottom of the inclined plate passes through the inside of the through slot.

[0007] Preferably, a clamping block is fixedly provided on the outside of the protective ring, the top of the inclined plate is fixed on the clamping block, and the side block is fixed on the outside of the mixing drum.

[0008] Preferably, a spiral hole is opened inside the side block, and a threaded rod is arranged inside the spiral hole.

[0009] Preferably, one end of the threaded rod extends to the surface of the inclined plate, and the other end of the threaded rod is fixedly provided with a handle.

[0010] Preferably, mounting plates are fixedly provided on the front and back sides of the side blocks, and the mounting plates are fixedly connected to the mixing drum by bolts.

[0012] Preferably, a driving wheel is fixedly provided at the working end of the motor, a driven wheel is fixedly provided at the bottom of the stirring shaft, and a transmission belt is provided outside the driving wheel and the driven wheel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model is designed with a protective mechanism, which makes it easy to install a protective ring on the top of the mixing drum during use. When the mixing drum is overfilled with raw materials, the protective ring blocks and protects concrete from overflowing from the top of the mixing drum under the rotation of the mixing blades, thereby preventing the concrete from overflowing. This reduces the probability of wasting concrete raw materials and the probability of concrete adhering to the outer wall of the mixing drum after overflowing, making it easier to use the mixer equipment.

The top of the mixing drum 100 penetrates into the interior of the annular groove 207. The locking member comprises a side block 201 and an inclined plate 202. A through groove 205 is provided inside the side block 201, and the bottom of the inclined plate 202 passes through the through groove 20 5, a block 208 is fixedly provided on the outside of the protective ring 200, the top of the inclined plate 202 is fixed on the block 208, the side block 201 is fixed on the outside of the mixing drum 100, a spiral hole is opened in the side block 201, and a threaded rod 204 is provided inside the spiral hole. When in use, the threaded rod 204 is screwed together with the spiral hole through a thread, one end of the threaded rod 204 extends to the surface of the inclined plate 202, and the other end of the threaded rod 204 is fixedly provided with a handle 206. Through the designed protective mechanism, it is convenient to install the protective ring 200 on the top of the mixing drum 100 during use. When the raw materials in the mixing drum 100 are overfilled, when the mixing blade 102 rotates, when the concrete overflows from the top of the mixing drum 100, the protective ring 200 is used to block and protect it, so as to prevent the concrete from overflowing outward, thereby reducing the probability of wasting the concrete raw materials and also reducing the probability of the concrete adhering to the outer wall of the mixing drum 100 after overflowing, so as to facilitate the use of the mixer equipment.

[0025] In the present embodiment, preferably, mounting plates 300 are fixedly provided on the front and back sides of the side block 201, and the mounting plates 300 are fixedly connected to the mixing drum 100 by bolts.
