Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1-3, in order to realize the feeding of a concrete mixer to one or more transport lines, an embodiment of the present invention provides a feeding device for a concrete mixer, which comprises a feeding pipe 1, a partition 2, a switching pipe 9 and a discharging pipe 10;
the discharging pipe 1 is fixedly sleeved at the bottom end of the concrete mixer, and is positioned in the discharging pipe 1;
the separating piece 2 is a cylinder, a passing cavity 3 is uniformly formed around the axis, the separating piece 2 is coaxially and fixedly connected to the inner wall of the bottom end of the blanking pipe 1, the center of the separating piece 2 is coaxially and rotatably provided with an adjusting shaft 4, the top end of the adjusting shaft 4 is coaxially and fixedly connected with a material separating plate 5, a blanking opening 6 is formed in the material separating plate 5, and the blanking opening 6 can be communicated with the passing cavity 3 when rotating along with the material separating plate 5;
the transfer pipe 9 is fixedly connected to the bottom ends of the blanking pipe 1 and the partition piece 2 and is communicated with the material passing cavity 3;
the discharging pipe 10 is obliquely and fixedly connected to the movable end of the switching pipe 9.
The bottom fixedly connected with mounting panel 7 of separator 2, the bottom surface fixed mounting of mounting panel 7 has accommodate motor 8, accommodate motor 8's output shaft and the coaxial fixed connection of bottom of regulating shaft 4.
Concrete flows out of a discharge pipe of the mixer, enters the discharging pipe 1, and is transported by a transport line used according to the requirement, the adjusting motor 8 is controlled to rotate by a fixed angle, so that the discharging opening 6 is communicated with the passing cavity 3 corresponding to the selected transport line, the concrete enters the switching pipe 9 through the discharging opening 6 and the passing cavity 3, the concrete in the switching pipe 9 flows into the discharging pipe 10, and finally flows out of a bottom pipe orifice of the discharging pipe 10 and falls on the transport line. The unloading pipe of transportation line is provided with the hopper, and in the concrete mixer truck was got into through the hopper to the concrete, because the material loading volume of transportation line is greater than the unloading volume of transportation line in the unit time, consequently the transportation line is through continuing to drive adjusting shaft 4 rotation after fully carrying for unloading opening 6 and another material chamber 3 intercommunication, and then realize another transportation line to the transportation of concrete, through accelerating the rotational speed of follow-up transportation line, can shorten the time that the concrete got into the hopper, and then make follow-up transportation line catch up preceding transportation line, begin to carry out the loading of concrete, and then can realize the simultaneous material loading of many concrete mixer trucks. And the loading efficiency of concrete is improved.
When the total amount of concrete required by loading is small, the rotation of the adjusting shaft 4 can be stopped, and one conveying line is always used for conveying the concrete, so that the condition that the excessive conveying lines are required to be cleaned after being used is avoided, and the maintenance cost is reduced.
The width of the blanking opening 6 is smaller than the distance between two adjacent material passing cavities 3, so that the adjusting shaft 4 drives the material separating plate 5 to rotate, and when the blanking opening 6 rotates between the two material passing cavities 3, the blanking pipe 1 is sealed; and adjusting the efficiency of concrete discharging according to the concrete loading efficiency.
As shown in fig. 1, in order to avoid that the concrete above the material separating plate 5 cannot flow out of the blanking pipe 1 completely, the top surface of the material separating plate 5 is obliquely arranged, the blanking opening 6 is positioned at the bottommost end of the top surface of the material separating plate 5, and the bottom surface of the material separating plate 5 is attached to the top end of the separating piece 2.
The top of the material separating plate 5 corresponding to the blanking opening 6 is set to be the bottommost end, and concrete above the material separating plate 5 can flow downwards from the top of the material separating plate 5, finally flows into the material passing cavity 3 from the blanking opening 6 and finally enters the transfer pipe 9. The bottom surface of separating plate 5 is laminated with the top of separating piece 2, carries out effectual support to separating plate 5 through separating piece 2, avoids simultaneously that the concrete in unloading pipe 1 gets into in the cavity that regulating spindle 4 is located.
As shown in fig. 1, in order to improve stability of the adapter tube 9, an annular buffer block 13 is fixedly connected to a tube orifice at the top end of the adapter tube 9 coaxially, an inclined surface inclined inwards is arranged at the top end of the buffer block 13, the buffer block 13 is fixedly connected to the material passing cavity 3 coaxially, and the inner diameter of the buffer block 13 is equal to the inner diameter of the adapter tube 9.
The buffer block 13 is fixedly connected with the inner walls of the feeding cavity 3 and the blanking pipe 1, and the buffer block 13 is fixedly connected with the top of the switching pipe 9, so that the stability of the switching pipe 9 is improved; the inner diameter of the buffer block 13 is smaller than that of the material passing cavity 3, so that the flow of concrete is reduced, and the concrete is prevented from being accumulated on a conveying line; the top end of the buffer block 13 is an inclined plane, so that the impact of the concrete is reduced while the flow of the concrete is guided.
As shown in fig. 1, in order to control the discharge amount of the discharge pipe 10, a screw shaft 12 is coaxially rotatably installed in the discharge pipe 10, and a screw blade is fixedly connected to the outer wall of the screw shaft 12. The top fixed mounting of discharging pipe 10 has unloading motor 11, and the coaxial fixed connection of output shaft and the top of screw axis 12 of unloading motor 11 drives screw axis 12 through unloading motor 11 and rotates, carries out the unloading, has realized the regulation and control to concrete unloading speed, and helical blade's edge is laminated with the inner wall of discharging pipe 10, and after unloader stopped using, through the rotation of the eastern helical blade of screw axis 12 area, scrapes the concrete that attaches to the inner wall of discharging pipe 10, keeps the inside unobstructed of discharging pipe 10.
As shown in fig. 1 and 3, in order to reduce the force used for rotating the material separating plate 5, a cutter 14 is disposed on the inner wall of the material separating plate 5 corresponding to the material discharging opening 6, and the top surface of the cutter 14 is inclined. When the material separation plate 5 rotates, the concrete flow in the blanking opening 6 needs to be cut off, and the cutter 14 can enable the material separation plate 5 to cut off the concrete flow more smoothly; while the cutter 14 facilitates scraping off the concrete adhering to the top end of the separator 2.
