Abstract

The utility model relates to a linkage type buffering unloading machine which comprises a machine foundation, a left shelf and a right shelf. The utility model is characterized in that a chain sprocket is arranged on the top of the machine foundation; two terminals of a chain matched to the chain sprocket are respectively connected with the left shelf and the right shelf. At least one cushion cylinder is arranged on the machine foundation. A piston axis of the cushion cylinder is fixed on the machine foundation. The outer shell of the cushion cylinder is connected with the left or the right shelf. The weight of the cargo causes the left and the right shelves to go up and down alternately when the cargo is unloaded. The cushion cylinder is characterized in that a plurality of bleeder ports are arranged both on the top and at the bottom of the cushion cylinder. When the cushion cylinder shell moves driven by the shelves, the piston bears the minimum damping force in the middle of the cushion cylinder shell and bears the maximum damping force both on the top and at the bottom of the cushion cylinder shell.

Description

Coordinated type buffering unloader

Technical field:

The utility model relates to a kind of unloading machinery, particularly a kind of coordinated type buffering unloader.

Technical background:

At present, the mode of unloading roughly has two kinds, and one is to use manpower (people's half the circumference of the sleeve where it joins the shoulder is shouldered) unloading, and two are to use the fork truck unloading.The former is the labour intensity height not only, and causes the damage of falling of goods when unloading large cargo easily; And the latter, then equipment cost height and consume fuel or electric power are very uneconomical.

Summary of the invention:

Technical matters, the purpose of this utility model provide a kind of coordinated type buffering unloader, and it has solved the labour intensity height of laborer when in the past unloading, fragile goods or the high problem of landed cost; And this coordinated type buffering unloader productive costs low, do not need the extra energy, we can say it also is a kind of equipment that is of value to environmental protection.

Technical scheme:

The purpose of this utility model is achieved in that a kind of coordinated type buffering unloader, comprises support and left and right thing frame, it is characterized in that the support top is provided with sprocket wheel, links to each other with right thing frame with left thing frame respectively with the chain two ends that sprocket wheel matches; Support is provided with at least one bounce cylinder, and the axis of the piston of bounce cylinder is fixed on the support; The shell of described bounce cylinder links to each other with left thing frame or right thing frame; Utilize the weight of goods self to make left and right thing frame do to replace upper and lower motion during unloading.

Described coordinated type buffering unloader, what it is characterized in that described bounce cylinder is to have some bleeder ports in the upper and lower of bounce cylinder shell, when the bounce cylinder shell moved under the drive of thing frame, piston was positioned at the minimum and suffered dumping force maximum when being positioned at cylinder top or bottom of suffered dumping force of bounce cylinder shell when middle part; Thereby obtain buffering in the upper and lower of cylinder block.

Beneficial effect, owing to adopted technical scheme described in the utility model, people only need to be positioned at the goods dislocation of eminence (on lorry) on the left thing frame or right thing frame of unloader top when unloading, left side thing frame or right thing frame will descend under the effect of goods gravity, and drive right thing frame or left thing frame upward movement, and owing to the thing frame links to each other with bounce cylinder, so, buffer action was all arranged in decline initial stage of thing frame and latter stage, the cargo damage problem of having avoided thing frame and ground-surface direct impact and having caused, reduced laborer's labour intensity simultaneously, and this coordinated type buffering unloader not needing extra power source, is a kind of equipment that is of value to environmental protection.

Description of drawings:

Fig. 1 is the structure principle chart of coordinated type buffering unloader described in the utility model.

Fig. 2 is the inner structure enlarged drawing of the left bounce cylinder on the described coordinated type buffering of Fig. 1 unloader.

Drawing explanation: 1-support, 21-left side thing frame, 211-left side pipe link, 31-left side bounce cylinder, 4-chain, 5-sprocket wheel, the 6-stand, 71-left piston, 81-left side cylinder axle, the right thing frame of 22-, the right pipe link of 221-, the right bounce cylinder of 32-, the right piston of 72-, the right cylinder axle of 82-, 311,312,313 and 311A, 312A, 313A-be respectively the bleeder port that is positioned at the upper and lower position of left bounce cylinder.

Be further described below in conjunction with drawings and Examples:

Fig. 1 is the structure principle chart of an embodiment of coordinated type buffering unloader described in the utility model.Fig. 2 is the inner structure enlarged drawing of the left bounce cylinder on the described coordinated type buffering of Fig. 1 unloader.

As seen, described coordinated type buffering unloader comprises support 1 and left thing frame 21, right thing frame 22, is provided with sprocket wheel 5 above the stand 6 of support 1, links to each other with right thing frame 22 with left thing frame 21 respectively with chain 4 two ends that sprocket wheel 5 matches from Fig. 1 and Fig. 2; The axis of the

piston

81 and 82 that support 1 is provided with left bounce cylinder 31 and right bounce cylinder 32, two bounce cylinders is separately fixed on the support 1; The shell of left side bounce cylinder 31 and right bounce cylinder 32 links to each other with right thing frame 22 with left thing frame 21 with right pipe link 221 by left pipe link 211 respectively; The shell upper of left side bounce cylinder 31 (right bounce cylinder too) and bottom have bleeder port 311,312,313 and 311A, 312A, 313A.

Principle of work, from state shown in Figure 1, left thing frame 21 is positioned at the unloader the top, at this moment goods to be unloaded can be placed on the left thing frame 21, left side thing frame 21 moves downward under the effect of goods gravity, at this moment because of right thing frame 22 links to each other with left thing frame 21 by chain 4, so right thing frame 22 upward movements; With left thing frame 21 is example, has only bleeder port 311A to work during setting in motion, at this moment, the resistance maximum that left side thing frame 21 is suffered is so kinematic velocity is also the slowest, when left thing frame 21 moves to left piston 71

bleeder port

312A and 313A are also opened, suffered resistance minimum, descending speed is the fastest; And when left thing frame 21 drops to its left piston 71 bleeder port 313 is sealed, resistance begins to become resistance maximum when bleeder port 312 is also sealed greatly, that is to say that the descending speed of the ambassador left side of the dumping force thing frame 21 of left bounce cylinder 71 before left thing frame 21 lands lowers rapidly in order to avoid damage goods; In the decline process of above-mentioned left thing frame 21, the rhythm that left bounce cylinder 31 enters damping state is the same with the rhythm of right bounce cylinder 32, has not just repeated at this course of action to right bounce cylinder 32.After above-mentioned left thing frame 21 lands, just can from left thing frame 21, goods be moved on to ground like a cork, at this moment right thing frame 22 is positioned at the unloader the top, only need when continuing unloading will goods be unloaded to place on the right thing frame 22 and get final product, that is to say that left and right thing frame is the effect of leaning on the weight of goods self in the unloading process, alternately be positioned at the top of unloader or below, whole process need not additional energy source.

For the goods to be unloaded that is positioned at differing heights, can be used by the length that chain 4 is set, be not described herein at this.
