Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-3, a quantitative output mechanism for mortar comprises a fixing ring 1 and a rotating wheel 2 rotatably sleeved on the side wall of an inner cavity of the fixing ring 1, wherein two through holes 3 are formed in the side wall of the rotating wheel 2, the axial directions of the two through holes 3 are the same and both point to the axial center of the rotating wheel 2, a mounting hole 11 is formed in the middle of the rotating wheel 2, each through hole 3 leads to the side wall of the inner cavity of the mounting hole 11, a piston plate 4 is slidably arranged in each through hole 3, the two piston plates 4 are connected through a rod body 5, a lifting mechanism is fixed on the rotating wheel 2, a lifting part of the lifting mechanism is connected with the rod body 5, the size of the cross section of each piston plate 4 is the same as that of an inner cavity channel of the through hole 3, the length of the rod body 5 is equal to the distance from the outlet end of one through hole; the fixed ring 1 is provided with an input hole 6 and an output hole 7 respectively, and when the passage of the input hole 6 is communicated with one through hole 3, the other through hole 3 is communicated with the output hole 7.

It should be noted that, the utility model provides a mortar ration output mechanism mainly sets up on output or transport pipe way, the shape of mounting hole 11 is acquiescently circular, the axis direction of mounting hole 11 is the same with the axis direction of runner, two through-holes 3 all run through runner 2, through-hole 3 mainly is circular also can be square etc. but owing to need match piston plate 4, piston plate 4 need ensure self can rise and fall at the inner chamber of through-hole 3 is perpendicular, in order to reduce the friction etc. with 3 inner chamber lateral walls of through-hole, the preferred circular here. The retaining ring in fig. 3 defines the position of the rotor 2 by means of an annular groove in the side wall of its inner cavity.

As shown in fig. 2, in the runner 2, the piston plates 4 in the two through holes 3 are connected by the rod body 5, and the lifting plate connecting rod 8 of the lifting cylinder 10 is used, so that the rod body 5 can be lifted and lowered in a reciprocating manner within a set range by changing the lifting range of the lifting cylinder 10 according to actual needs, and the lifting cylinder 10 is fixed on the runner 2.

The length of the rod body 5 is equal to the distance from the outlet end of one through hole 3 to the bottom end of the other through hole 3, wherein the outlet end refers to the area of the through hole 3 connected to the outer side wall of the rotating wheel 2, and the bottom end of the through hole 3 refers to the area of the single through hole 3 connected to the inner side wall of the rotating wheel 2.

The other side of the rotating wheel 2 in fig. 2 is provided with two connecting rods 8 for connecting a rotating mechanism, and the rotating mechanism is mainly realized by positive and negative rotation of a motor. The fixed ring 1 is respectively connected with the input hole 6 and the output hole 7, when the rotating wheel 2 rotates to a certain angle, the through hole 3 can be connected with the input hole 6 or the output hole 7, and when the input hole 6 is connected with the through hole 3, the other through hole 3 is connected with the output hole 7. The inlet hole 6 in fig. 1 is located right above the runner 2, and the storage area in the inlet hole 6 and above the inlet hole 6 is filled with mortar, at this time, the piston plate 4 at the inlet hole 6 stops moving downwards under the driving of the lifting cylinder 10, so that a certain volume of mortar is introduced into the through hole 3 from the inlet hole 6. The piston plate 4 at the other end connected with the rod body 5 starts to move downwards, and all substances in the through hole 3 positioned below are pushed out of the current through hole 3. When the upper piston plate 4 moves to the bottom end of the through hole 3, the edge of the surface of the lower piston plate 4 just meets the bottom surface of the runner 2, and the meeting is smooth transition between the surface of the piston plate 4 and the surface of the runner 2.

The surface of the side, far away from the rod body 5, of the piston plate 4 is a curved surface, the radian of the curved surface is the same as that of the side wall of the runner 2, when the piston plate 4 positioned below is just connected with the bottom surface of the runner 2, the runner 2 rotates at the moment, and the through hole 3 positioned below does not have any mortar residue due to the fit of the piston plate 4 and the fixing ring 1. The mortar stored in the upper through hole 3 gradually moves to the lower output hole 7 during the rotation, and the piston plate 4 in the upper through hole 3 starts to move downwards, so that the whole process is performed in a reciprocating manner.

Fig. 3 is a half-sectional view of the fixing ring 1, the fixing ring 1 itself does not rotate or move during the mortar feeding process. The connecting rods 8 on the rotating wheel 2 (the number and the shape of the connecting rods 8 can be modified as required), the rotating wheel 2 shown in fig. 1-3 rotates 180 degrees (the reciprocating rotation can solve the problem that a pipeline for conveying gas on a cylinder is blocked or torn off due to one-way rotation), then rotates in the reverse direction, and repeats the rotation, the rotating mechanism, namely a forward and reverse rotating motor, realizes the rotation of the rotating wheel 2, but the rotating mechanism can accurately stop in a corresponding area, a buffer block is fixedly connected outside the fixed ring, and the buffer block is positioned on the rotating path of the connecting rods. Namely, a buffer structure such as a buffer block 9 in the figure is arranged, and the buffer structure is made of rubber. When runner 2 rotates to corresponding angle, when through-hole 3 just faced input hole 6, the connecting rod 8 that sets up on the runner 2 lateral wall just in time can strike mutually with buffer block 9, then does not remove the electric power on the slewing mechanism this moment, keeps the state of buffer block 9 and connecting rod 8 contact, when piston plate 4 moves down to piston plate 4 and stops, then slewing mechanism begins the reversal. The corresponding circuit control, i.e. the working time control and circuit design of the lifting cylinder 10 and the rotating mechanism, etc., can be set and adjusted by persons skilled in the art.

The position of the input hole 6 on the fixing ring 1 is not limited to the illustrated position, and may form an angle other than 90 ° with the ground. If the inclination angle is too large, a certain pressure needs to be applied to the mortar storage area connected to the input hole 6, and if the viscosity of the mortar is high, a certain pressure needs to be applied to the mortar storage area, so that the piston plate 4 in contact with the mortar can be ensured to be introduced into the through hole 3 after moving.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
