Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
Referring to fig. 1-2, the stirring mechanism for a small-sized concrete mixer in the utility model comprises a main shaft 1 and a driving member for driving the main shaft 1 to rotate, wherein a stirring part 4 is arranged on the main shaft 1, a plurality of buffer members 2 are uniformly distributed on the periphery of the main shaft 1, one end of each buffer member 2 far away from the main shaft 1 is connected with a stirring arc piece 3, gaps are reserved among the stirring arc pieces 3, flexible blocking layers for filling the gaps are arranged between the stirring arc pieces 3 and the upper end and the lower end of the main shaft 1, the stirring part 4 is arranged on the periphery of the stirring arc piece 3, and after the stirring part 4 is stressed, the buffer members 2 can deviate to drive the stirring arc pieces 3 and the stirring part 4 to change the relative positions with the main shaft 1.
The device drives stirring portion 4 through main shaft 1 and stirs the concrete, set up the buffer 2 that can deformation dodged in main shaft 1 periphery, and be connected through the several stirring arc piece 3 that buffer 2 will keep the clearance, make when meetting great, the grit of hardening, stirring portion 4 conduction atress to buffer 2 department, buffer 2 deformation drives stirring portion 4 skew and dodges, stirring portion 4 and grit have been avoided producing stronger rigid contact, wear and tear has been reduced, device life has been increased, because all there is the clearance between each stirring arc piece 3, main shaft 1 and stirring arc piece 3, there is the concrete can get into the clearance, influence the problem of device normal use, the device is through setting up the flexible protective layer that is used for shutoff clearance between each clearance, avoid this problem, simultaneously be worth noting that flexible protective layer's available material is a lot, the material that should use intensity higher.
Referring to fig. 3, the buffer member 2 is a spring, the main shaft 1 is cylindrical, and one end of the spring away from the main shaft 1 is connected with the stirring arc 3.
The device utilizes the spring to utilize the characteristic that the spring can stretch out and draw back and skew deformation for stirring portion 4 can dodge the grit, and it is worth mentioning that the required kinetic energy of spring's elasticity coefficient and deformation should select for use and be greater than the stirring power of normal smooth stirring ordinary material, and this design is only to the grit that excessively hardens, avoids the too high collision of intensity and hard contact with this effect of guaranteeing normal stirring, avoids stirring portion 4 too to take place the condition of dodging easily, reaches normal stirring effect.
Referring to fig. 4-6, the buffer member 2 includes a connecting rod 21 and a sliding block 22, the main shaft 1 is prismatic, a plurality of sliding grooves 11 are provided on each end surface of the main shaft, two sliding blocks 22 are slidably connected in the sliding grooves 11, the sliding blocks 22 are rotatably connected with the connecting rod 21, one ends of the two connecting rods 21 far away from the sliding blocks 22 are rotatably connected with the stirring arc 3 through the same rotating shaft, and the connecting rods 21 are not perpendicular to the upper end surfaces of the sliding blocks 22.
The device is through setting up connecting rod 21 and slider 22 so that when receiving great stress, connecting rod 21 drives slider 22 and slides in spout 11, and two connecting rod 21 angles change simultaneously, and stirring arc piece 3 and main shaft 1 interval change reaches the purpose that drives stirring portion 4 deflection, dodges the grit.
Further, the slide 22 and the stirring arc 3 are both connected with the connecting rod 21 in a torque rotation manner.
The slider 22 can be set to the friction block, produces great frictional force when sliding, makes it be difficult for sliding, rotates the connection and has the moment of torsion, can further provide the rigidity that is greater than required stirring power for stirring portion 4 when stirring normal material, avoids the too condition of taking place to dodge of stirring portion, reaches not normally stirring effect.
Referring to fig. 7, the stirring portion 4 is a discontinuous break auger.
Because the auger has the effect that drives the material and remove towards certain direction, through setting up stirring portion 4 into the auger rather than ordinary stirring roller, increased stirring effect, discontinuous auger compares in traditional auger can cooperate this design to realize dodging of stirring portion 4.
The working principle of the embodiment is as follows:
when the device is used, the driving piece is started to enable the main shaft 1 to drive the stirring part 4 to rotate, concrete is stirred, the deformable buffer piece 2 is arranged on the periphery of the main shaft 1, and the stirring arc pieces 3 with gaps are connected with the main shaft 1 through the buffer piece 2, so that when larger and hardened sand is met, the stirring part 4 conducts stress to the buffer piece 2, the deformation of the buffer piece 2 drives the stirring part 4 to deviate and avoid, the stirring part 4 is prevented from being in stronger rigid contact with the sand, and the service life of the device is prolonged.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
