Abstract

The utility model provides a ground wheel-driven small bale pick-up trolley which belongs to mechanical apparatus capable of picking up bales which are bound by a small bale binding machine and dropped onto the ground, elevating the bales to a certain loading height, and automatically overturning the bales onto a working platform, so that the bales can be palletized onto a vehicle by manual work. The small bale pick-up trolley is hitched to the left side of a trailer or a truck via a drawbar pin assembly, and a ratchet-and-pawl mechanism is driven in a unilateral manner by ground wheels on the right side thereof, thereby transmitting the power to an elevating chain assembly; the small bales can be picked up, grabbed and elevated to a certain height from the ground under the action of a welding piece of a bale-pressing plate as a component of an elevator assembly and the elevating chain assembly; on one hand, the bales are gradually separated from a welding piece of an elevating claw plate as a component of a platform assembly in the elevating process by propping against a rear wall which forms a certain inclination with the elevator assembly, and on the other hand, the small bales are guided by a welding piece of a bale-stopping rod and thus overturned onto the working platform automatically at the same time; and the bales are palletized onto the trailer or the truck by manual work.

Description

Little side's bale is picked up car

Technical field

The utility model is a kind ofly little side's bale binder can be dropped on ground bale and pick up, and elevator is turned on the workbench automatically to certain loading height, uses the plant equipment of piling on the artificial car then.

Background technology

External herbage harvesting operation is at present based on little side's bale harvest technology, so the workload of cargo handling operations such as the picking up of the little side's bale in field, shipment, piling is very big; In order to solve the mechanized operation problem of cargo handling operations such as the picking up of the little side's bale in field, transportation, stacking; Towed and the self-propelled automatic bale trailer of the various models that U.S.'s knob dutch company is produced is plant equipment of functions such as present state-of-the-art in the world fusion bale is picked up, shipment, destacking; Unit comprehensive mechanization degree and productivity ratio are all very high, operating cost also is on the low side in the bale treatment system, and people just can finish and pick up bale, row's buttress, transportation and whole bale buttress fitly is discharged to whole work of storage grass point automatically onboard from ground; So the towed and self-propelled automatic bale trailer of the various models that U.S.'s knob dutch company is produced has obtained to use widely on some large-scale agriculture and animal husbandry fields of states such as the U.S., Australia; But also exist complex structure, hydraulic system manufacturing and difficult in maintenance, cost an arm and a leg, shortcoming such as year availability is low.

China's present stage, little side's bale binder obtained in vast pastoral area using widely, and still little side's bale is picked up most of users and adopted artificial loading and unloading, labour intensity height, inefficiency; The homemade little side's pick up bale loader tool that does not also have advanced technology, reasonable in design at present in China.

Summary of the invention

For realizing the demand of little side's pick up bale loader toolization, the utility model provides a kind of employing to rely on land wheel transmission elevating chain, pick up the extracting bale from ground, and bale risen to certain height, automatically be turned to then on the workbench, rely on and manually just can on trailer or truck, carry out piling; Latch and trailer or truck left side articulates on this machine and the hitch frame assembly, articulate or take apart very easy so that the careless point of storage transported the car load bale back apace by means of transport; When the entire job unit need be grown distance transfer plot, can easily little side's bale be picked up car and be turned to transporting position, the traction hook that is articulated in trailer or truck back upward just can fast running.

The technical scheme that its technical problem that solves the utility model adopts is: the structure that adopts the monolateral driving of right side land wheel, wheel idle running leftwards; When facility were in the travel position fast running, drive sprocket can separate with land axle by ratchet mechanism, thereby elevating chain is stopped operating, and prevented the wearing and tearing of doing nothing and chain link hypervelocity and damaged.

The elevator assembly is by left and right side plate, baling plate, side retaining grid, compositions such as rear wall.Elevating chain just is contained on the elevator assembly; Can smoothly bale be picked up elevator in order to adapt to when wide of little side's bale or leptoprosopy land, the inboard spacing of left side plate is greater than wide of little side's bale; The gap of baling plate inner face and elevator frame working face can be regulated within the specific limits automatically, and bale is pressed on the elevator assembly rear wall all the time, makes the unlikely slippage from the elevator claw-plate of bale.

In order to protect the unlikely damage when running into stone etc. of the elevator chain link that has claw-plate, the sliding palm of firm protection that the fixing fixed head of minor sprocket down in elevator frame lower end has adopted steel plate to be stamped to form; When unit is turned left, pick up the compartment side plate and the wheel of car and trailer or truck and run foul of each other in order to prevent little side's bale, be fixed with side retaining grid on the right side.

The girder of hitch frame adopts seamless steel pipe to be welded, and structure is lightly firm; For the difference that adapts to various trucies and trailer articulates height, the towing pin assembly can be adjusted arbitrarily in certain scope; Hitch frame guide section entry design flue shape can adapt on the ground along little side's bale of putting, tiltedly put even traverse, can both import in the elevator frame smoothly; The crossbeam of hitch frame rear end is connected with the ground wheel assembly by the link assembly.

The platform assembly is made up of parts such as platform soldering member, retaining bundle bar soldering member, front hurdle soldering members; Bale is during from elevator assembly elevator to liftoff certain high platform assembly, rely on elevator on the one hand and put up the rear wall at certain inclination angle, bale is separated with the elevating chain claw-plate in uphill process gradually, again simultaneously by retaining bundle rod guidance to bale is turned on the workbench automatically, so that piling onboard after manually picking up.When complete machine upset is in travel position, should simultaneously the seam of retaining bundle bar be changed over transporting position, in order to avoid articulate and unit is broken when turning.

The elevating chain assembly is made up of upper and lower minor sprocket, tightener sprocket and elevating chain, and wherein three minor sprockets are general fully.
