[0002] Among building materials, materials that can be transformed from slurry into a solid stone-like body through a series of physical and chemical reactions, and can bind other solid materials into a whole with a certain mechanical strength are collectively referred to as cementitious materials. Cementitious materials refer to materials that can bind loose and blocky materials into a whole in the process of changing from plastic slurry into a hard stone-like body through their own physical and chemical reactions. They are also called cementitious materials. The spacing between the spiral belt and the pipe wall of the existing cementitious material screw conveying equipment is mostly more than 10mm.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The embodiment of the present invention provides a screw conveying device for filling cementitious materials, including a base 1, which is generally a horizontal bracket, but can also be inclined; a conveying motor 2 is fixedly installed on the side wall of the base 1, that is, the seat body of the conveying motor 2 and the base 1 remain relatively stationary; a conveying circular groove 3 is fixedly installed on the top of the base 1, and the conveying circular groove 3 is composed of an external shell and an internal circular channel. Generally, the external shell is made into a metal cavity structure to save materials, and a shaftless auger blade 4 is rotatably installed in the conveying circular groove 3. The advantage of the shaftless auger blade 4 is that the internal colloid will not be as easy to adhere to the central axis as the shafted auger, and the outer edge of the shaftless auger blade 4 is close to the conveying The inner wall of the conveying circular groove 3 is fitted, so that the inner wall of the channel of the conveying circular groove 3 is scraped by the outer edge of the shaftless auger blade 4 to ensure that there is no condensation or adhesion on it; one end of the shaftless auger blade 4 is fixedly connected to a transmission disk 5, and the fixed connection between the two can be achieved by welding, bolt fixing, etc.; the conveying motor 2 is transmission-connected to the transmission disk 5, that is, any transmission connection method can be adopted between the two, and no specific restriction is made in the present invention; one end of the conveying circular groove 3 close to the conveying motor 2 is fixedly connected to a feed pipe 6, and the other end of the conveying circular groove 3 is fixedly connected to a discharge pipe 7, and the discharge pipe 7 is in the opposite direction to the feed pipe 6, and a premixing mechanism 8 is provided on the feed pipe 6.

[0026] Furthermore, the transmission disc 5 is fixed to the shaftless auger blade 4 by a plurality of fixing columns 9 fixedly penetrated on the shaftless auger blade 4. In the present invention, holes are opened on the shaftless auger blade 4, and then the fixing columns 9 are welded into the corresponding holes. This method has a greater supporting strength and a more uniform force, thereby preventing the shaftless auger blade 4 from being broken due to uneven force.

[0027] Furthermore, the present invention provides a specific transmission connection method: a motor cover 10 is fixedly installed at one end of the base 1 close to the conveying motor 2, a rotating mounting portion 11 is arranged inside the motor cover 10 to seal the corresponding end of the conveying circular groove 3, a mounting circular groove is arranged on the rotating mounting portion 11, a transmission disc 5 is rotatably arranged in the mounting circular groove of the rotating mounting portion 11, a transmission shaft 12 is fixedly installed at the center of the transmission disc 5, a limited position slide groove 13 is arranged on the transmission shaft 12, a slide cylinder 14 is also sleeved on the transmission shaft 12, the slide cylinder 14 is slidably nested in the limited position slide groove 13 through a protrusion, a bevel gear 15 is fixedly sleeved on the slide cylinder 14, and the conveying motor 2 is provided with a rotating mounting portion 11, and the transmission disc 5 is rotatably arranged in the mounting circular groove of the rotating mounting portion 11, and the transmission disc 5 is provided with a transmission shaft 12 fixedly installed at the center of the transmission disc 5, a limited position slide groove 13 is arranged on the transmission shaft 12, and a slide cylinder 14 is sleeved on the transmission shaft 12, and the slide cylinder 14 is slidably nested in the limited position slide groove 13 through a protrusion, and a bevel gear 15 is fixedly sleeved on the slide cylinder 14. The machine 2 is fixedly installed in the motor cover 10, and the output shaft of the conveying motor 2 is fixedly sleeved with a bevel gear 2 16, which meshes with the bevel gear 1 15, and the diameter of the bevel gear 15 is larger than the diameter of the bevel gear 2 16. The present invention forms a spline-like rotating transmission structure through the cooperation between the protrusion on the inner wall of the slide cylinder 14 and the limiting slide groove 13 on the surface of the transmission shaft 12, thereby realizing the rotational movement of the transmission shaft 12 without affecting the axial reciprocating sliding of the transmission shaft 12, and the bevel gear 15 and the bevel gear 2 16 not only realize the driving of the slide cylinder 14 but also enable the conveying motor 2 and the transmission disk 5 to achieve the purpose of speed reduction transmission.

[0028] Furthermore, a transmission shaft 2 18 is connected to the end of the transmission shaft 12 away from the conveying circular groove 3 through a rotating connecting piece 17, and a linkage rod 19 is rotatably mounted on the end of the transmission shaft 2 18 away from the conveying circular groove 3. A vibration motor 20 is fixedly installed in the motor cover 10, and a driving disk 21 is fixedly installed on the output shaft of the vibration motor 20. A driving shaft 22 is fixedly installed on the edge of the driving disk 21. The driving shaft 22 is rotatably connected to the end of the linkage rod 19 close to the driving disk 21. The rotating connecting piece 17 is generally an ordinary bearing. The rotation of the transmission shaft 12 can be separated from the rotation of the transmission shaft 2 18 by the rotating connecting piece 17. The present invention also transmits the eccentric motion to the transmission shaft 2 18 through the eccentric motion of the driving shaft 22 on the driving disk 21 and the linkage rod 19. The rotating connecting piece 17 only isolates the rotational motion, while the axial motion is transmitted normally, so that the transmission shaft 2 18 reciprocates axially.

[0029] Furthermore, a reinforcing plate 23 is fixedly mounted on the motor cover 10 , and a rotation hole is provided on the reinforcing plate 23 so as to be rotatably sleeved on the output shaft of the vibration motor 20 , so as to enhance the stability of the eccentric motion.

[0030] The working principle of the present invention is:

[0031] When the device of the present invention works normally, the raw materials of the filling cementitious material are mixed into a filling cementitious body through a general premixing mechanism 8 (for example, concrete only needs to be mixed evenly by a mixing device, so the specific premixing mechanism 8 is not limited here. When the filling cementitious material is concrete, the premixing mechanism 8 is a stirring device). After mixing, the filling cementitious material enters the conveying circular groove 3 through the feeding pipe 6, and the power of the conveying motor 2 is transmitted to the bevel gear 1 15 through the bevel gear 2 16, thereby driving the slide cylinder 14 to rotate, the slide cylinder 14 drives the transmission shaft 12 to rotate, and then drives the transmission disk 5 to rotate, and the transmission disk 5 drives the shaftless auger blade 4 to rotate through the fixed column 9, thereby transporting the mixed filling cementitious material to the discharge pipe 7.

[0032] When the conveying groove 3 of the device of the present invention is about to coagulate or when the device of the present invention is cleaned according to a preset frequency, while the shaftless auger blade 4 is rotating and conveying, the vibration motor 20 is started to eccentrically move the drive shaft 22 on the drive disk 21, and then the eccentric movement is transmitted to the transmission shaft 2 18 through the linkage rod 19, so that the transmission shaft 2 18 reciprocates axially, and the reciprocating extension and contraction of the transmission shaft 2 18 drives the transmission shaft 1 12 to reciprocate (when the transmission disk 5 is in the initial position, a telescopic gap 33 is formed between the rotating mounting portion 11 and the transmission disk 5), and finally drives the shaftless auger blade 4 to reciprocate axially. During cleaning, the shaftless auger blade 4 can collide with the cleaning, which helps cleaning or helps secondary mixing of concrete during normal transportation.

[0033] The premixing mechanism 8 includes an adjusting and releasing device 24 arranged at the top of the feed pipe 6, and both ends of the adjusting and releasing device 24 are fixedly connected with a feed elbow 25, and the top of the feed elbow 25 is fixedly connected with a stirring tank body 26, and the top of the stirring tank body 26 is open, and a feed hopper 27 is fixedly installed at the top opening of the stirring tank body 26, and a motor bracket 28 is fixedly installed at the top of the feed hopper 27, and a stirring motor 29 is fixedly installed on the motor bracket 28, and a stirring shaft 30 is rotatably installed in the stirring tank body 26, and the stirring shaft 30 is fixedly connected to the output shaft of the stirring motor 29. The adjusting and releasing device 24 includes a connecting body 31 for connecting the two feed elbows 25 and the feed pipe 6, and two sliding sealing plates 32 for blocking the feed elbows 25 are slidably installed in the connecting body 31 through a slide groove. A flexible plate (generally made of plastic or other materials) is provided on the outer edge of the shaftless auger blade 4 to reduce the wear on the inner wall of the conveying circular groove 3.

[0034] Because the mixing of raw materials requires a certain amount of time, the present invention provides two sets of mixing equipment for alternating mixing to save time. On the other hand, the valve with a sliding sealing plate 32 can be closed during the sliding process to prevent the valve from condensing.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
