Description

Technical Field

[0001] The present invention relates to the technical field of raw material crushing, and in particular to a raw material crushing device for 3D printing biological construction. Background Art

[0002] Bioconstruction is a new type of engineering construction model that uses organisms as carriers for engineering construction, or develops new materials, new equipment and new processes based on organisms. It is mainly represented by microbial construction, plant construction, animal construction and bionic construction. It has typical characteristics such as green, low-carbon and integration with nature.

[0003] In the field of biological construction of 3D printing, building materials, biomass growth substrates and microorganisms are used. Before use, the building materials and biomass growth substrates need to be crushed, and then the crushed building materials and biomass growth substrates are mixed with the microorganisms.

[0004] At present, a pulverizer is usually used to pulverize and mix them in one operation. During the pulverization process, the pulverization effect of building materials and biomass growth substrates is better. However, when the pulverized building materials or biomass growth substrates need to be mixed with microorganisms, the mixing effect of the two types of raw materials is poor due to the narrow blades used for pulverization. It takes a long time to achieve complete mixing during the mixing process, and the mixing efficiency is low; and during the mixing process, the pulverized building materials and biomass growth substrates are further pulverized when the blades rotate, resulting in particles that are too small, so that the particle size cannot meet the requirements. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a raw material crushing device for 3D printing biological construction, which solves the technical problem that the existing integrated crushing and mixing machine further crushes the raw materials after crushing them, resulting in the particles being too small.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A raw material crushing device for 3D printing biological construction includes a stirring barrel, wherein a stirring shaft is arranged in the stirring barrel; one end of the stirring shaft is movably connected with a stirring blade, and the other end of the stirring shaft extends out of the stirring barrel and is connected to a stirring motor, and the stirring motor is fixed on a supporting frame; an angle adjustment component is arranged on the stirring blade.

[0008] In this scheme, when crushing materials such as building materials and biomass growth substrates, they are placed in a mixing barrel; the mixing blades are adjusted by an angle adjustment component so that the angle between the plane where the mixing blades are located and the direction of rotation is 15-30 degrees. At this time, the leading edge of the mixing blades crushes the building materials when they rotate; after crushing, the building materials are mixed with microorganisms. During mixing, the mixing blades are first adjusted by an angle adjustment component so that the plane where the mixing blades are located is perpendicular to the tangent direction of their rotation. At this time, the sides of the mixing blades are in contact with the materials during rotation, so the contact area between the two is large and the degree of stirring is high, thereby achieving good mixing between the building materials and the microorganisms; at the same time, the sides of the mixing blades are in contact with the building materials during the mixing process, thereby avoiding further crushing of the crushed building materials to cause the particles to be too small.

[0009] Furthermore, the angle adjustment assembly includes a connecting rod, one end of which is movably connected to the stirring blade via a ball joint structure; the other end of the connecting rod is movably connected to a lifting ring; the lifting ring is rotatably connected to the periphery of a fastening nut; and the fastening nut is threadedly connected to the stirring shaft.

[0010] In this solution, the fastening nut is rotated to move up and down along the stirring shaft, driving the lifting ring to rise and fall synchronously. During the lifting process, the lifting ring pulls the stirring blade to rotate through the connecting rod to adjust the angle between the plane where the stirring blade is located and its rotation direction; the stirring blade crushes the building material raw materials through its leading edge position during crushing, and mixes the building material raw materials and microorganisms through the side of the blade during mixing.

[0011] Furthermore, one end of the stirring shaft connected to the stirring blade is connected to a shaft seat, and a rotating hole is opened around the shaft seat; the end of the stirring blade is provided with a rotating shaft, and the rotating shaft is installed in the rotating hole around the shaft seat.

[0012] In this solution, when the connecting rod pulls the stirring blade to adjust the angle, the rotating shaft at the end of the stirring blade rotates relative to the shaft seat to achieve the adjustment of the stirring blade angle.

[0013] Furthermore, a circle of rotation groove is formed on the periphery of the fastening nut, and the inner ring of the lifting ring is rotatably connected in the rotation groove.

[0014] In this solution, when the fastening nut is rotated, the lifting ring can remain stationary in the rotating groove of the fastening nut, while driving the lifting ring to move up and down.

[0015] Furthermore, the support frame includes a base plate, and the mixing barrel is fixed on the base plate through a lower support frame; an L-shaped motor bracket is installed on the base plate, and a mixing motor is fixed at the end of the motor bracket; the mixing motor is located directly above the mixing barrel.

[0016] Furthermore, a discharge port is provided at the bottom of the mixing barrel, and a manual valve is provided on the discharge port; a receiving box is placed at the bottom of the discharge port.

[0017] In this solution, after mixing, the manual valve on the discharge port is opened, and the materials in the mixing barrel directly fall into the receiving box and can be taken out in a centralized manner.

[0018] Furthermore, the lower support frame is a cylindrical barrel structure, and a fan-shaped opening is opened at the bottom of the barrel structure;

[0019] The material receiving box is a fan-shaped disc; the fan-shaped disc is placed just below the material discharge port through an opening at the bottom of the cylinder structure.

[0020] In this solution, the design facilitates the material receiving box to extend into the lower support frame to receive the material.

[0021] Furthermore, the leading edge of the stirring blade is sharpened.

[0022] In this solution, the stirring blades are sharpened so that the building material raw materials can be crushed quickly during crushing.

[0023] The beneficial effects of the present invention are:

[0024] The raw material crushing device for 3D printing biological construction provided by the present invention drives the lifting ring to rise and fall along the stirring shaft by rotating the fastening nut. The lifting ring pulls the stirring blade to rotate along the rotating shaft through the connecting rod to adjust its angle, so that it can stop and switch the corresponding operation mode during the crushing and mixing operation. The operation is relatively convenient, suitable for different scenes, and saves the cost of replacing equipment. At the same time, after crushing, the stirring blade is adjusted to make its plane perpendicular to the tangent direction of its rotation. At this time, the blade uses its width to fully stir the building material raw materials and microorganisms, with a high degree of mixing and a fast mixing speed; and during mixing, the cutting edge of the front edge of the stirring blade will not continue to crush the building materials and biomass growth substrates, avoiding the formation of particles that are too small.

[0038] like Figure 3 As shown, one end of the stirring shaft 4 connected to the stirring blade 11 is connected to the shaft seat 9, and a rotating hole is opened around the shaft seat 9; the end of the stirring blade 11 is provided with a rotating shaft 10, and the rotating shaft 10 is installed in the rotating hole around the shaft seat 9; when the connecting rod 7 pulls the stirring blade 11 to adjust the angle, the rotating shaft 10 at the end of the stirring blade 11 rotates relative to the shaft seat 9 to adjust the angle of the stirring blade 11.

[0039] like Figure 4 As shown, a circle of rotating groove is opened on the outer periphery of the fastening nut 6, and the inner ring of the lifting ring 5 is rotatably connected in the rotating groove; when the fastening nut 6 is rotated, this design allows the lifting ring 5 to remain stationary in the rotating groove of the fastening nut 6, while driving the lifting ring 5 to move up and down.
