Description

The suspension type earth auger

Technical field

The utility model relates to a kind of earth auger, relates to specifically a kind ofly being applicable to that afforestation is digged pit, electric power stringing cloth bar digs pit, protects the grassland to dig the suspension type earth auger of the operations of digging pit such as netting fence stake hole.

Background technology

In order to preserve the ecological environment, protect soil vegetative cover, prevent desertification now, concede the land to forestry, the afforestation task is more and more heavier.Planting trees at present digs pit also to adopt basically manually finishes, and labour intensity is very big, and efficiency is but very low, waste of manpower and time; In order to reduce labour intensity, increase work efficiency, also use earth auger at present.Though earth auger in the market can reduce labour intensity, increase work efficiency, but exist more following problems: because existing earth auger does not have overload protection arrangement, so digging hollow place or running under the situation of big resistance such as hard soil property, ratchel, tree root, fragile facility parts, as gearbox inside drive disk assembly and tractor driving member etc., cause damage, increase the tree planting cost and delay the duration; Safety pin is installed in some employing of existing earth auger on output shaft, in case when running into impact resistance, shear pin breakage though play the certain protection effect, is reinstalled safety pin and lost time, reduce operating efficiency; Now a lot of earth auger gearbox designs are unreasonable, and intensity is low, and is easy to wear, influences service life; Present employed earth auger is in work and transportation mid frame shakiness, and the easy swing of drill body when amplitude of fluctuation is big, has reduced safety, hurts sb.'s feelings easily, and especially in the place of working when rough and uneven in surface, drill body is swung bigger, influences the service life of facility; It is fragile that simultaneously present earth auger also exists when running into strong resistance casing, not steady when frame rise or landing, fragile tractor and mechanical parts own, and now a lot of earth augers do not have rotating, run into strong resistance or break down drill body is risen, can only lean on artificial or other mechanical taking-ups.

Summary of the invention

The purpose of this utility model is to provide a kind of reliable working performance, and is safe in utilization stable, long service life, high efficiency, suspension type earth auger easy and simple to handle.

The purpose of this utility model is to realize by following technical scheme:

A kind of suspension type earth auger, comprise frame, power transmission shaft, gearbox and drill body, its structural feature is: said frame is " people " font frame, one end of this frame is installed and the hinged bearing pin in tractor central tie rod hole, the other end of this frame is two underframe of " people " font frame, the bottom welding hinged pipe of this underframe is installed runing rest at said frame front, and the suspension pin that connects suspension plate under the tractor is equipped with at these two ends, runing rest bottom respectively.Runing rest is installed on the frame during the utility model work, following side mounting pin is installed under the tractor in the suspension plate ball-type hole, frame is lifted place and the whereabouts that drill bit need be digged pit, driving the inner driving member of gearbox by tractor motive power output shaft through power transmission shaft screws in drill bit in the soil, along with the drill body rotation, soil is shed around hole, digs when requiring the degree of depth, operation hydraulic suspension frame rises drill bit, finishes the cave process of digging.

At the adjustable plate of said frame front mounting strap adjustment hole, to install in the said adjustment hole and regulate bolt, limit base is installed at said adjustable plate place, and this limit base connects said runing rest below by jointed shaft.

By regulating bearing pin adjuster is installed on said runing rest top, this adjuster comprises the regulating shaft that is installed in the regulating sleeve, installs on this regulating shaft and regulates stage clip, and the other end of said regulating sleeve is installed and regulated leading screw.

Said power transmission shaft one end connects the tractor inter-axle shaft; the other end of this power transmission shaft connects the power shaft of overload protective device; said overload protective device comprises shell; a pair of arc spring compressing tablet, a pair of friction plate and a pair of compressing tablet, the end cap of mounting strap power shaft on the said shell are installed in this shell.

Hinged pipe on the said frame connects respectively joint chair, and is said the said adjuster leading screw of joint chair upper end connection.

Said gearbox is installed between said two one or two joint chairs, and the sliding axle of this gearbox mounting strap handle is installed two groups of relative bevel gears on this sliding axle.

On the output shaft of said gearbox terminal pad is installed, this terminal pad other end connects drill body, and this drill body comprises drilling rod, and soil lifting plate, cutting edge and following apex point are arranged on this drilling rod.

Advantage of the present utility model is: the utility model frame adopts " people " font, and gearbox is installed on " people " font frame, and this method of attachment can reduce vibration, and the protection casing is not impaired; It is safe and reliable to utilize the utility model to dig pit, and the facility long service life is durable in use, and stable working shakes for a short time, can effectively raise labour efficiency, and reduces labour intensity.

The further advantage of the utility model is: the utility model increases the frame range by limit base on the frame and adjustable plate, and drill body increases, thereby the degree of depth of digging pit is increased; Because the utility model has further been installed adjuster, can guarantee that by adjusting leading screw on the adjuster and internal regulation compression spring length frame drill body when falling always is in plumbness, finish pit excavation work smoothly, and make the hole of being dug vertical, automatically regulate by the compression spring simultaneously and reduce vibration, lift at drill body, machinery integral is steady in the transportation, drill body unmatched back swing, avoid hurting sb.'s feelings, increased security performance; The utility model is owing to further installed overload protective device, when running into excessive resistance such as pan soil matter, ratchel or tree root, friction plate in the protector is thrown off with compressing tablet, automatically cut off power, drill body stops the rotation and can protect facility itself and tractor drive disk assembly not impaired, prolongs facility service life; The utility model is regulated sliding axle with handle owing to further the sliding axle that has handle has been installed during work, makes it to move up and down, and realizes the positive and negative rotation of drill body.
