In the paddy rice planting process, the most difficult, the most bitter, the most tired part is exactly rice transplanting, and rice transplanting is in the past all manually carried out, not only speed is slow, efficient is low, and the running out of space of people, the people is very tired out at the end of the day, so the rice transplanter that is used for substituting people's rice transplanting has just been arranged.Rice transplanter has a floating drum that is used for rice transplanting, this also is the main working parts of rice transplanter, the lifting of floating drum is generally all controlled by hydraulic system, existing hydraulic system comprises hydraulic pump and hydraulic valve of controlling the lifting of floating drum oil cylinder that power is provided, these two hydraulic parts of pump valve separate, link together by pipeline, such one is that volume is big, price comparison is high, the centre also will connect by pipeline, the seepage that hydraulic oil is arranged most importantly is exactly: the height according to the field that can not be real-time rises and falls and controls the height of floating drum.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of sensing profiling dynamic Control integrating device that is used for rice transplanter is provided, its pump valve one, and can accomplish rises and falls according to the field in real time controls the height of floating drum.
Technology solution of the present utility model is as follows:
A kind of sensing profiling dynamic Control integrating device, comprise valve body, pump oil-in, oil cylinder interface, oil return opening and rotary valve chamber are arranged on the valve body, described pump oil-in and pump chamber are communicated with, a pair of intermeshing active efflux gear and slave pump gear are arranged in pump chamber, be equipped with in the described rotary valve chamber one when not rotating and oil return opening communicates, when rotating and the rotary valve that communicates of oil cylinder interface.
Described a kind of sensing profiling dynamic Control integrating device, described rotary valve comprises a spool, the two ends of described spool are stretched out described two ends of valve body face and can freely be rotated in described rotary valve chamber, there is a sealing ring middle part of described spool, there is a flat bar end, be fixed with a collar that prevents that spool from sliding on another end, the end in the rotary valve chamber near described flat bar is equipped with a dust ring that prevents that dust from entering.
Described a kind of sensing profiling dynamic Control integrating device, described pump chamber is made of driving gear chamber that the active efflux gear is installed and the driven gear chamber that the slave pump gear is installed, described driven gear chamber and pump oil-in communicate, and described driving gear chamber and rotary valve chamber communicate.
Also have one and pump oil-in overflow valve that communicate, that be used for control system pressure in the described a kind of sensing profiling dynamic Control integrating device, described valve body.
The utility model beneficial effect is:
The control device that this is novel, when rice transplanter carries out field rice transplanting operation, floating drum rises and falls and moves with the field all the time, so just drive rotary valve spool by a connecting rod that is connected with rotary valve spool, floating drum rotates together, thereby control hydraulic circuit, the floating drum that makes rice transplanter promotes together, descends with the broken terrain profiling.And this new structure compactness, volume is little, pressure is high, from absorption is good, leakage is little, pressurize is reliable, be the desirable auxiliary products of all kinds of rice transplanters.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is this novel structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is this novel schematic diagram.
Embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1～3; A kind of sensing profiling dynamic Control integrating device, comprise valve body 1, pump oil-in 101, oil cylinder interface 102, oil return opening 103 and rotary valve chamber 104 are arranged on the valve body, described pump oil-in and pump chamber 105 are communicated with, the pump oil-in is used for from the fuel tank 8 interior sucking-off hydraulic oil of rice transplanter, a pair of intermeshing active efflux gear 2 and slave pump gear 3 are arranged in pump chamber, be equipped with in the described rotary valve chamber one when not rotating and oil return opening communicates, when rotating and the rotary valve 4 that communicates of oil cylinder interface.The through hole 106 that four diameters are arranged is 9mm around the valve body is used for mounting screw 108 valve body and pump chamber lid 107 are fixed, and sealing ring is all arranged on pump oil-in, oil return opening, prevents leakage of oil.The oil cylinder interface is used for being connected with the oil cylinder 9 of controlling buoy lifting, offers the used hydraulic oil of oil cylinder lifting.
