Utility model works principle:

The utility model discloses a kind of tractor loading and unloading device, in use, frame shape elevator platform is installed on tractor locomotive Rear portion, using telescopic ram set by the elevator platform bottom, by the lifting arm being fixed together, lower lifting arm, It is I-shaped slot column along the elevator platform two sides, slides up and down displacement.When sliding up and down, the both ends point of the upper lifting arm It in the internal chute of not embedding I-shaped slot column, is positioned using upper positioning slide plate, the lower lifting arm is positioned using lower positioning slide plate.

In order to reduce friction when sliding up and down, corresponding to the groove that the upper lifting arm is formed, it is equipped with pulley I, it is corresponding In it is described it is lower positioning slide plate and lower lifting arm formed groove, be equipped with pulley II, in this way utilize pulley, greatly reduce plate with Friction between plate.

Fork plate, fork arm are also symmetrically arranged on the lower lifting arm, the fork plate, fork arm utilize connecting shaft, in connecting hole Different angles can be arbitrarily rotated, when needing to ship big cotton packet, big cotton packet is usually cylindrical shape, can remove intermediate fork Bar, leaves the fork plate of two sides, and big cotton packet is clamped between two fork plates, fork plate under gravity, the fork plate side of can rotate To the arc surface of planar support cotton packet will not scratch the packaging film that big cotton is wrapped in this way, very convenient reliable.The connection It is hingedly, to be packed up so that the fork plate is foldable when not working between axis and fork plate.

The entrucking of the agricultural product of the cotton packet bigger for volume or other dress packets, can use the cotton installed on lifting arm Packet lifting machine handgrip is spent to complete.Such as when grabbing bale of cotton operation, the handgrip of the utility model is placed in using lifting rope Then the top of the bale of cotton is transferred, boom opens around, surrounds the bale of cotton, is recycled lifting rope to lift boom, is at this moment grabbed needle Can be inserted into the bale of cotton, boom is since bale of cotton weight pushes, lifting hole(eyelet) clamping boom so that boom is no longer displaced, four booms from Surrounding is firmly grasped the bale of cotton and is sling, and the bale of cotton can be carried out carrying or stacking by the mobile cantilever of crane.

The effect of the retaining mechanism is to hang between wall and lifting hole(eyelet) when grabbing the different size of bale of cotton for adjusting Spacing, in order to preferably grab different size of bale of cotton service.

The bottom support frame is when the bale of cotton is larger, to be put in bale of cotton lower part, four boom decentralization crawls When, using the structure of the hollow square tube of cross intersection construction, the bitch is just inserted into hollow square tube, in the crawl bale of cotton When moving up, the bottom support frame of lower part holds up the bale of cotton, plays the role of stable equilibrium.

When having quantity more but the goods and materials of small volume, can also be carried out using jacking pallet above the elevator platform Entrucking, the jacking pallet lower section are equipped with jacking axis, and the jacking axis is fixedly connected with upper lifting arm, with upper lifting arm It moves up and down, the jacking axis drives the jacking pallet, can move up and down along perforation, in this way can be by the goods and materials of small volume Automatic lifting entrucking is carried out, manpower is saved.In order to reduce jacking axis perforate between friction, the elevator platform top surface On, pulley blocks are equipped with close to perforation, are in contact using jacking axis curved surface with the pulley face of four pulleys, relative rolling contact, greatly Mutual friction is reduced greatly.

Preferably, can be equipped with auxiliary universal wheel, mounting rack below the elevator platform, this is a kind of auxiliary installation Frame, universal wheel can be freely rotated on the ground.The structure of the lateral shaft is divided into three sections, and centre is circular shaft section, and two sides are rib Axis of a cylinder section, the section of best prism shaft part are octagon, and effect is that fixed auxiliary universal wheel does not allow it to rotate.Middle part is circular shaft Type assists universal wheel to lose fixed function in this position, can arbitrarily rotate.Universal wheel can will be assisted from circular shaft when not operation Section is moved on prism shaft part position, and auxiliary universal wheel is lifted, is fixed on not job position.The effect of this structure is Deficiency when tractor weight is less than handling weighing items is made up, a part handling object is supported to prevent the pressure at tractor rear portion Only tractor is pressed to obtain disequilibrium.

Preferably, supporting plate can also be put in the fork plate of the lower lifting arm, for going up and down the object agriculture for being easy to leak down Product goods and materials can also add reinforcing bar between the I-shaped slot column of the elevator platform two sides, play the role of reinforcing.

For the utility model when being lifted or grabbing the material used for agriculture such as the bale of cotton, it is existing for being utilized to entrucking and stacking speed 3 times or more of fork truck conveyer, effectively improve working efficiency, are the necessary equipments that cotton stores up transport locomotive.This is practical Novel use is extensive, can be used for the bale of cotton, velveteen packet, stacking, entrucking inside and outside the storehouses such as soft fibre (flax wool) packet, It can be used for farmland wheat straw bundle, the entrucking of low-rise building materials is transported.It is safe and efficient in use, manpower is greatlyd save, efficiency is very It is high.It is raised in shipment in traditional, it is very big for dress watermelon, Chinese cabbage loss, it is average in 5-8%, use this handler This loss can be made to drop to 1% or so.

Compared with prior art, the advantages of the utility model: it is simple and reasonable, the bulky bale of cotton, grass can be directed to Pile etc. material used for agriculture, roping locomotive are able to carry out reliably jack up handling, can various structures fitment combination use, purposes is wide It is general, time labour is saved, work efficiency is high, is a kind of economical and practical tractor loading and unloading device.
