Embodiment
To it should be pointed out that in this part to the description of concrete structure and description order it is only explanation to specific embodiment, should not be considered as there is any restriction to protection domain of the present utility model.In addition, when not conflicting, the embodiment in this part and the feature in embodiment can combine mutually.
Refer to Fig. 2 and Fig. 3, the utility model embodiment provides a kind of pumping mechanism, it hopper 3 comprising two pumping units be separated from each other and be connected with two pumping units be separated.Two pumping units be separated from each other are the first pumping unit and the second pumping unit, and the material of suction from suction in this hopper 3, and pumps by two pumping units be separated from each other.Because above-mentioned two pumping units are separated, therefore, can to reduce in pumping procedure impact each other, avoid whole pumping mechanism Cyclic flexion under pumping state, improve the working life of pumping mechanism.
This first pumping unit comprises the first power cylinder 11, first water tank 12, first conveying cylinder 13.The two ends of this first conveying cylinder 13 are connected on this first water tank 12 and this hopper 3, and this first power cylinder 11 is connected to this first water tank 12 one end away from this first conveying cylinder 13.The first piston bar 111 of this first power cylinder 11 is located in this first water tank 12, the end of this first piston bar 111 is provided with first piston 112, and this first piston 112 is slidably disposed in this first conveying cylinder 13.
This second pumping unit comprises the second power cylinder 21, second water tank 22, second conveying cylinder 23.The two ends of this second conveying cylinder 23 are connected on this second water tank 22 and this hopper 3, and this second power cylinder 21 is connected to this second water tank 22 one end away from this second conveying cylinder 23.Second piston rod 211 of this second power cylinder 21 is located in this second water tank 22, the end of this second piston rod 211 is provided with the second piston 212, and this second piston 112 is slidably disposed in this second conveying cylinder 23.
Be provided with distributing valve (not shown) in this hopper 3, this distributing valve alternately with this first carry cylinder 13 or this second carry cylinder 23 to be connected, enter for a point batching body or pump.This distributing valve can be S pipe valve, C valve, skirt valve or gate valve, also can be other forms of distributing valve.
The first above-mentioned water tank 12 is not communicated with the second water tank 22, easily in the process of pumping, there is the phenomenon that in the first water tank 12 and the second water tank 22, the water surface sharply rises or declines, be specially: suction side (carrying out suction for the first pumping unit), due to the rollback of first piston 112, water in this first conveying cylinder 13 will pour in this first water tank 12, causes the water surface of this first water tank 12 sharply to rise; Stock side (carrying out stock for the second pumping unit), because the pumping of the second piston 212 is advanced, the water in this second water tank 22 will pour in this second conveying cylinder 23 and cause the water surface of this second water tank 22 sharply to decline.Water in this first water tank 12 and this second water tank 22 sharply increases, and easily causes the water in water tank to overflow.
In order to solve the above problems, the utility model preferably, this first water tank 12 and this second water tank 22 side respect to one another offer inlet (not shown), connecting plate 4 is provided with between this first water tank 12 and this second water tank 22, this connecting plate 4 offers through hole (not shown), the inlet of the first water tank 12 is connected by the through hole of connecting plate 4 with the inlet of the second water tank 22, the joint of this through hole and each inlet is provided with seal element (not shown), sealing element is by the inlet of this first water tank 12, the inlet of this through hole and this second water tank 22 is tightly connected, thus make this first water tank 12 carry out circulating with the water in this second water tank 22 and can not leak, and then ensure can not to occur in the process of pumping the phenomenon that the water surface in the first water tank 12 or the second water tank 22 sharply rises or decline.The quantity of this through hole can be multiple, may also be only one.
The pumping mechanism of the utility model embodiment also comprises pumping unit auxiliary device, and this pumping unit auxiliary device comprises water tank bearing 51, hopper bearing 52, connecting rod 53 and automobile chassis 54.This water tank bearing 51 is connected with this first water tank 12 and this second water tank 22, to carry this first water tank 12 and this second water tank 22.This hopper bearing 52 is connected with this hopper 3.One end of this connecting rod 53 is hinged on this hopper bearing 52.This automobile chassis 54 is hinged with the other end of this connecting rod 53 and this water tank bearing 51 respectively.This pumping unit auxiliary device adopts three point articulated modes this first pumping unit and this second pumping unit to be connected with automobile chassis 54, improves the stability (this has higher stability by triangle to determine) of connection.Preferably, this water tank bearing 51 comprises the first water tank bearing 511 and the second water tank bearing 512, wherein, this the first water tank bearing 511 is connected with this first water tank 12, this the second water tank bearing 512 is connected with this second water tank 22, and also namely the first water tank bearing 511 and the second water tank bearing 512 are split-type structural.This automobile chassis 54 is hinged with this first water tank bearing 511 and this second water tank bearing 512 simultaneously.Because above-mentioned two water tank bearings are separated, therefore, the first pumping unit and the second pumping unit can be reduced in pumping procedure to impact each other.
The first conveying cylinder, second of the pumping mechanism that the utility model embodiment provides carries the required precision on cylinder length direction lower, even if there is certain deviation in the length of above-mentioned two conveying cylinders, because this first water tank and this second water tank are split type, therefore, the impact of this second conveying cylinder and the second water tank can not be subject in the process that this first conveying cylinder pump send, the radial direction of this first conveying cylinder does not stress, and certainly just can not produce buckling phenomenon yet.In addition, this pumping mechanism is in pumping or suction process, can not be affected between this first pumping unit and this second pumping unit, in the process of work, only tension and compression distortion axially can be there is between each parts of above-mentioned two pumping units self, mutually can not interfere and produce lateral bending distortion, even if therefore improve pumping pressure, also buckling phenomenon can not be produced, pumping mechanism can be avoided to cause eccentric wear because of Cyclic flexion to this first pumping unit and this second pumping unit, be conducive to the working life of improving this pumping mechanism.
The utility model other embodiment still provides a kind of pumping equipment, it is provided with above-mentioned pumping mechanism.Because above-mentioned pumping mechanism has above-mentioned technique effect, thus this pumping equipment has above-mentioned technique effect too, the specific implementation process of its appropriate section is similar to the above embodiments, and the specific implementation process of other parts see the associated description of prior art, hereby can not repeat.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
