When the multi-cylinder stirring shaft is used, the reduction gearbox drives the stirring shaft to rotate so as to stir concrete materials in the multi-cylinder. The existing horizontal concrete mixer has the problems that: the stirring shaft needs frequent relative barrel rotation, so the good sealing relation between the stirring shaft and the barrel can not be ensured all the time, slurry flows outwards along a gap between the stirring shaft and the barrel often, if the slurry directly flows into the speed reduction box, the speed reduction box can be damaged, the speed reduction box is the core equipment of the horizontal concrete mixer, the price is high, and once the speed reduction box is damaged, the maintenance cost of a user can be greatly increased.

Disclosure of Invention

An object of the utility model is to provide a horizontal concrete mixer to among the solution prior art, the thick liquid in the barrel can flow into the reducing gear box along the (mixing) shaft and cause the technical problem that the reducing gear box damaged.

In order to solve the technical problem, the utility model discloses well horizontal concrete mixer's technical scheme as follows:

a horizontal concrete mixer comprises a frame, wherein a horizontally placed barrel is arranged on the frame, a mixing shaft is arranged in the barrel, one end of the mixing shaft penetrates out of one side of the barrel to form a torque input end, a reduction gearbox is further arranged on the frame and connected with the torque input end, a slurry blocking disc of an annular structure is sleeved between the reduction gearbox and the barrel through a fixing structure on the periphery of the torque input end, and the inner wall of the slurry blocking disc is in sealing fit with the torque input end.

The horizontal concrete mixer is a double-shaft horizontal concrete mixer.

The fixing structure comprises at least two screw mounting holes distributed along the circumferential direction, each screw mounting hole radially penetrates through the slurry blocking disc along the torque input end, connecting threads are arranged on the hole walls of the screw mounting holes, fastening screws are connected to the connecting threads in a threaded mode, and the inner ends of the fastening screws are abutted to the torque input end.

The torque conveying end is provided with an annular positioning groove, and the inner end of the set screw is of a conical structure with the end part positioned and extending into the annular positioning groove.

The end part of the torque input end is provided with a transmission key groove, and the transmission key groove is connected with the reduction gearbox through a key block.

The utility model has the advantages that: the utility model discloses in, keep off the dish through fixed knot constructs on the moment of torsion input outer peripheral face between reducing gear box and barrel fixed a thick liquid, the thick liquid keeps off the inner wall of dish and the sealed cooperation of moment of torsion input outer peripheral face, even if there is the thick liquid like this to move towards the reducing gear box along the (mixing) shaft through the gap between (mixing) shaft and the barrel, the thick liquid also can be kept off the dish by the thick liquid and block and can not continue to flow towards the reducing gear box to avoid the thick liquid to enter into the reducing gear box and cause the reducing gear box to damage.

fig. 2 is an enlarged view at a in fig. 1.

Detailed Description

The embodiment of the middle horizontal concrete mixer of the utility model is shown in figures 1-2: the horizontal concrete mixer is a double-shaft horizontal concrete mixer, and comprises a frame, a cylinder 6 arranged on the frame, a reduction gearbox 1 and a motor (not shown in the figure) for providing power for the reduction gearbox. The barrel is horizontally arranged, two stirring shafts 5 which are arranged in parallel at intervals from left to right are arranged in the barrel, and the horizontal concrete mixer is called a double-shaft horizontal concrete mixer because of the two stirring shafts.

The number of the reduction gearbox and the motor is respectively corresponding to the number of the stirring shafts, one end of the stirring shaft penetrates out of one side of the barrel to form a torque input end 4, a transmission key groove is formed in the end part of the torque input end 4, and the transmission key groove is directly connected with the torque output end of the reduction gearbox through a key block 8. All of which are prior art and will not be described in detail herein.

A bearing seat 7 is fixed on one side of the shell of the reduction gearbox facing the stirring shaft, and a rotating bearing 3 is arranged between the bearing seat and the torque output end 4 of the stirring shaft.

An annular positioning groove 11 is formed in the torque output end 4 between the reduction gearbox 1 and the barrel 6, the outer side of the annular positioning groove 11 is connected with a slurry baffle disc 2 of an annular structure through a fixing structure in a sleeved mode, the inner wall of the slurry baffle disc 2 is in sealing fit with the torque input end 4, and the slurry baffle disc is preferably made of rubber materials. The fixing structure comprises a plurality of screw mounting holes 9 distributed along the circumferential direction, each screw mounting hole radially penetrates through the slurry blocking disc along the torque input end, connecting threads are arranged on the hole walls of the screw mounting holes, each connecting thread is connected with a set screw 10 in a threaded manner, and the inner end of each set screw 10 is a conical structure 12 of which the end part is positioned and extends into the annular positioning groove.
