Utility model content
The purpose of this utility model is to provide one kind during the work time, can manually be adjusted into liquid stream according to drilling condition
Amount changes drilling machine rotating speed, is filled with the manual feed liquor flow-rate adjustment for adapting to the hand drill of different hardness coal rock layer drilling needs
It puts.
Hand drill described in the utility model it is manual into flow-adjusting device, the hand drill includes base
This is rectangular rack, and hydraulic motor is arranged on the center of rack, and the short side of rectangle rack is hand handle；On hydraulic motor
Setting to adjust hydraulic motor into the regulating valve of flow quantity, the regulating valve includes valve body, has feed pathway in valve body,
The switch core that can be moved is set on valve body；When switch core moves, the through-flow face between switch core and feed pathway can be changed
Product, and then change into flow quantity；It is provided between valve body and switch core under normal conditions so that switch core is in closing feed pathway
The elastic element of position；Valve body is stretched out in the outer end of switch core；Have to swing close to the place of regulating valve in rack and be connected to machine
Turnover panel on frame, the turnover panel upper end opposite with switch core outer end is set pushes away column for the movement of pull switch core；The lower end of turnover panel
It is hinged with one end of pull rod, the other end of pull rod is fixedly linked with the knob set near hand handle.
The beneficial effects of the utility model：When holding hand handle, finger can pull knob, by pull rod turnover panel be driven to put
It is dynamic, it pushes away column i.e. pull switch core and acts.The distance controlling that the size of switch core displacement distance is shaken hands by finger pull, so that
Flow area size is controlled by finger.In this way, even if hand-held drill during the work time, can also can be manual according to drilling condition
It adjusts into flow quantity, changes drilling machine rotating speed, to adapt to the drilling needs of different hardness coal rock layer.
As manual being further improved into flow-adjusting device to above-mentioned hand drill, in rack and turnover panel
Between be provided with resetting spring, resetting spring under normal conditions, turnover panel be in thereon push away position of the column away from switch core.
As manual being further improved into flow-adjusting device to above-mentioned hand drill, push away column and pass through screw thread
Pair is connected on turnover panel.It can so rotate and push away the relative position that column change pushes away column and turnover panel, and then change pushes away column and switch core
Position, facilitate adjusting switch core mobile range.

Specific embodiment
Include essentially rectangular rack 1, hydraulic motor 2 referring to the hand-hold emulsifiable solution drill shown in Fig. 1,2 to set
At the center of rack, the output shaft 21 of hydraulic motor is extended downwardly for jointed rod.
The short side 11 of rectangle rack is hand handle；It sets to adjust hydraulic motor into flow quantity in hydraulic motor side
Regulating valve 3.Referring to Fig. 3, regulating valve 3 includes valve body 4, has feed pathway 5 in valve body.Lead in the feed liquor communicated with emulsion source
Switch core 6 in the hypomere 56 in road is set, spool is provided in the epimere 57 of the feed pathway communicated with hydraulic motor inlet
7。
The left end for the switch core that can axially move left and right sets blind hole 66, right end（Outer end）Stretch out valve body.It is located at
Spiral compression spring 8 in blind hole is arranged between hydraulic motor outer wall and switch core, and spiral compression spring 8 is under normal conditions so that open
Guan Xin is in the conical surface 67 on switch core and is contacted with hypomere feed pathway 56 and close the position of feed pathway.
