Abstract

The invention relates to a slag discharging tool used for quickly grabbing straws, sundries and sludge in a biogas digester. A lockable gripper consists of a clip, a clip disk, a holding rod, a piston, a hydraulic jack, a fixed seat, a carriage hand buckling hasp and a connecting block, wherein the clip is hinged with the clip disk connected with the holding rod and is hinged with the piston, the hydraulic jack is connected with the holding rod by the fixed seat, one end of the carriage hand buckling hasp is hinged with the piston through the connecting block, the other end of the carriage hand buckling hasp is hinged with the holding rod, the connecting block is fixed on the piston, and the piston is in the holding rod. The invention provides a gripping device capable of being clamped and locked, which is reasonable in design and low in cost, has a simple structure, and is easy to process and convenient to use.

Description

But the clamper of locking

Technical field: the deslagging instrument that the present invention relates to grab fast in a kind of methane-generating pit rake stalk, foreign material, what mud.

Technical background: biogas can utilize ight soil, stalk, weeds, waste residue, waste material etc. on the spot as the energy in rural area, after fermentation; Both produced biogas, these waste materials also can be used as fertilizer, and because the degree height that becomes thoroughly decomposed makes fertilizer efficiency higher; Biogas raw materials such as ight soil by fermentation after, most parasitic ovums are killed, and can improve the rural health condition; Reduce the infection of disease, produce, live and brought outside many getting well to the peasant.But methane-generating pit in use for some time, need be with inserting virgin material after the cleaning of natural pond slag, methane-generating pit ability normal gas producing; Slag difficult removing in natural pond is a major reason of its application of restriction, when cleaning methane-generating pit and municipal sewage pipe network, often is that the pond is young; The pond content is big, and foreign material such as while stalk do not close clamper, and general mechanical lock locking mechanism can't be accomplished; Some small-sized equipment except that the natural pond slag that are exclusively used in are also arranged at present, use the hydraulic lock locking mechanism, but need hydraulic motor; Cooperations such as gauge tap need electricity or internal combustion engine drive, in use have certain problem.

And general handheld holder does not have lockable mechanism; When drawing high gripping object, one side promotes, and it is gruelling that one side is pressed from both sides thing; For example application number is that 200610153360.0 Chinese patent discloses a kind of methane tank slag tapping equipment; Comprise a mobile jib welding transverse slat, two of transverse slat connects two risers with hinge respectively, and two risers and two dig box and also are articulated and connected.The center hinge that the bottom of a pull bar and two is dug in the middle of the box is joined, and in mobile jib, vertically moves.This slag tapping equipment is owing to be that the hand push pull bar is downward, digs box and opens and take the natural pond slag, and hand is pull bar upwards; Dig box and close, the gravity direction that digs natural pond slag in the box is with to open the thrust direction of digging box consistent, and to dig the direction of pull of box opposite with closure; Oversize when upwards carrying the natural pond slag owing to bar; Hand can not upwards haul pull bar always, digs the gravity of natural pond slag in the box and can open digging box, causes splashing of natural pond slag; This slag tapping equipment is a boxlike, is difficult to remove for natural pond slags such as the stalk of methane-generating pit upper surface, weeds.

Summary of the invention: the objective of the invention is to overcome the deficiency of prior art, provide a kind of reasonable in design, simple in structure, be easy to process, cost is low, easy to use can clamp and the clamping device of locking.

The present invention realizes like this; But the locking clamper by clip, clip dish, holding rod, piston, hydraulic jack, holder, compartment hand buckle snap-on, contiguous block is formed, clip is hinged on the clip dish that holding rod is connected with and with piston hinge and links to each other, hydraulic jack is connected on the holding rod through holder; The compartment hand is buckled snap-on one end and is linked to each other with piston hinge through contiguous block; The other end is hinged on the holding rod, and contiguous block is fixed on the piston, and piston is in holding rod.The compartment hand is buckled snap-on and is made up of ring, handle, little axle; The hole that one end of ring passes in the contiguous block links to each other with piston, and the other end of ring is hinged on the handle, an end dissociative of handle; The other end of handle is connected on the holding rod through little axle, and hydraulic jack is connected on the holding rod through holder.

Adopt technique scheme when extracting the stalk marsh gas pond; What buckle snap-on through adjustment hydraulic jack, compartment hand according to folded material; Clamper can be deep into any position in the main pond; The material of gripping any amount can directly be buckled the continuous piston of snap-on pulling contiguous block with the compartment hand when material after a little while and drive clip motion locking and clamp material.When material available hydraulic jack promotion contiguous block and the motion of piston drive clip for a long time, locking holding rod and piston space distance are also clamped material.

Description of drawings

Fig. 1 is this invention sketch map

Figure row: 1 holding rod, 2 pistons, 3 rings, 4 handles, 5 little axles, 6 clips, 7 holders, 8 hydraulic jack, 9 contiguous blocks, 10 clip dishes.

The specific embodiment

As shown in Figure 1, holding rod 1 is the steel pipe of an external diameter 42cm hollow, the steel pipe of 2 external diameter 38cm of piston hollow; The snap-on that ring 3, handle 4, little axle 5 are formed is that common Yangze river and Huai river boxcar hand is buckled snap-on; Clip 6 is rakes of pintongs circular arc type, and holder 7 is that three block plates are welded, and hydraulic jack 8 is 3 tons of hydraulic jack; Contiguous block 9 adopts the 10cm steel plate, and clip dish 10 adopts the 10cm steel plate.

As shown in Figure 1; During use clamper is goed deep in the methane-generating pit hand-held holding rod 1 and open clip 6 and aim at gripping objects, handle the hydraulic jack 8 that is fixed on the holder 7 and withstand contiguous block 9 and drive pistons 2 and clamp material, make clip 6 in the clip dish 10 clamp object and pull out in the pond then; When unloading when putting material; Buckle snap-on and be connected in the handles 4 that the little axle 5 on the holding rod 1 links to each other and drive ring 3 through depressing the compartment hand, make hydraulic jack 8 returns that join with contiguous block, promote piston 2 clip 6 is opened.

Claims

1. but locking clamper; By clip, clip dish, holding rod, piston, hydraulic jack, holder, compartment hand buckle snap-on, contiguous block is formed, it is characterized in that: clip is hinged on the clip dish that holding rod is connected with and with piston hinge and links to each other, and hydraulic jack is connected on the holding rod through holder; The compartment hand is buckled snap-on one end and is linked to each other with piston hinge through contiguous block; The other end is hinged on the holding rod, and contiguous block is fixed on the piston, and piston is in holding rod.
