Abstract
The utility model relates to a pneumatic cotton picker which is composed of a diaphragm pump, a cotton suction duct, a cotton discharge duct, and an intermediate transit chamber, wherein, the diaphragm pump and the intermediate transit chamber are communicated via a channel which is provided with a flower blocking device, the lower part of the intermediate transit chamber is communicated with the cotton suction duct, a one-way gate valve which can only be opened toward the inner direction of the intermediate transit chamber is arranged at the communicating point, the upper part of the intermediate transit chamber is communicated with the cotton suction duct, a one-way gate valve which can only be opened toward the outer direction of the intermediate transit chamber is arranged at the communicating point, and a one-way impurity removing gate valve which can only be opened toward the outside of a shell is arranged on the lower part of a shell body of the diaphragm pump. The utility model has the advantages of simple structure, little power consumption, high cotton picking efficiency, and low impurity percentage of picked cotton.
Description
The utility model relates to a kind of air-sucking type cotton picker.
Present air-sucking type cotton picker mainly is made up of cylinder, cotton suction duct, cotton-discharging tube and settling banker.Reciprocating motion by cylinder piston alternately changes the positive negative pressure in the settling banker, finishes and inhales cotton and tell cotton process.Utilize this cotton picker cotton picking more manually to adopt cotton and improved efficient.Yet owing between cylinder piston and the cylinder barrel sliding friction is arranged, and easily gas leakage, so kinetic equation loss is bigger.Again since cylinder relatively heaviness and manufacture difficulty are bigger, the cylinder of making the big flow of big stroke is difficulty very, has influenced the further raising of adopting cotton efficient so greatly.
The purpose of this utility model provides a kind of simple in structure, adopts the higher air-sucking type cotton picker of cotton efficient.
In order to achieve the above object, sucking cotton picking device of the present utility model is by membrane pump, cotton suction duct, cotton-discharging tube, and transporting room is formed.Between membrane pump and the transporting room by channel connection, be provided with cotton-blocking equipment in the passage, the bottom of membrane pump shell has impurity discharging port, the impurity discharging port place is provided with the unidirectional family of power and influence that can only outwards open, the transporting room below is communicated with cotton suction duct, connection place be provided with can only direction be opened in transporting room the unidirectional family of power and influence, the transporting room top is communicated with cotton-discharging tube, connection place is provided with the unidirectional family of power and influence that can only open to the transfer outdoor direction.
Aforesaid air-sucking type cotton picker, its cotton-blocking equipment have the wind wheel of many quils for the surface.
Aforesaid air-sucking type cotton picker, its cotton-blocking equipment also can be the mesh sieve.
Aforesaid air-sucking type cotton picker is equipped with filter screen in the cotton suction duct, mesh diameter is 2～3cm.
After adopting such structure, because membrane pump is simple than air cylinder structure, in light weight, make easily, therefore can make enough greatly, be implemented in the very short very big throughput of time generation, make its suction adopt cotton and inhale than cylinder and adopt cotton better continuity is arranged, adopt cotton efficient and improve greatly; Again since the diaphragm movement of membrane pump to be reciprocating motion and its air-tightness of fricton-tight friction good than cylinder, so this device kinetic equation loss is few.In addition, because the utility model is provided with screen pack in cotton suction duct, be provided with cotton-blocking equipment in the transporting room and pump case is provided with impurity discharging port, so the cotton percentage of impurity that this device is plucked is lower.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
With reference to Fig. 1, present embodiment comprises membrane pump 1, the shell of membrane pump is communicated with transporting room 5 by passage, be provided with cotton-blocking equipment 4 in the passage, cotton-blocking equipment is the blowing wind wheel of band quil, also can be the mesh sieve, the membrane pump outer casing underpart has impurity discharging port, the impurity discharging port place is provided with the unidirectional family of power and influence 9 that can only outwards open, and transporting room below is communicated with cotton suction duct 8, connection place be provided with can only direction be opened in transporting room the unidirectional family of power and influence 6; Be provided with filter screen 7 in the cotton suction duct, transporting room top is communicated with cotton-discharging tube 2, and connection place is provided with the unidirectional family of power and influence 3 that can only open to the transfer outdoor direction.
Its operation principle is as follows:
After membrane pump is driven, barrier film is reciprocating, when barrier film during to left movement, produces negative pressure in the transporting room of right side, transporting room is communicated with the place with cotton suction duct the unidirectional family of power and influence opens, the unidirectional family of power and influence at transporting room and cotton-discharging tube place closes, and the right side cotton suction duct is in the cotton suction tube, the big blade of elimination when through filter screen, cotton enters transporting room, the quil wind wheel just changes with air-flow, and cotton is tangled by quil, and impurity is inhaled in the pump case; When barrier film moves right, malleation in the transporting room of right side, the unidirectional family of power and influence who is communicated with the place with cotton suction duct closes, the unidirectional family of power and influence who is communicated with the place with cotton-discharging tube opens, the counter-rotating of quil wind wheel, cotton breaks away from quil with powerful wind-force and enters cotton-discharging tube by transporting room, and impurity discharging port the unidirectional family of power and influence open, and impurity is discharged to finish and once adopted cotton process.During diaphragm movement, work simultaneously and pluck two row cottons in the membrane pump left and right sides.
Claims (4)
