Utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and provides a kind of agricultural straw fork truck, and this fork truck is applicable to field off-road operation and uses, and solves the difficult problem that stalk stores up utilization and sugarcane entrucking carrying.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of agricultural straw fork truck, comprises the power machine part of fork truck, it is characterized in that: also comprise door frame lifting mechanism and clamping switching mechanism, described clamping switching mechanism is arranged on door frame lifting mechanism, and described door frame lifting mechanism is arranged on power machine;
Described clamping switching mechanism is made up of turnover bracket, holding frame, jaw, prong, overturning oil cylinder and clamping oil cylinder, described turnover bracket is arranged on door frame lifting mechanism as lifting part, described holding frame is arranged on turnover bracket by rotating shaft, described jaw is rotationally connected by rotating shaft and holding frame upper end, described prong is connected to the lower end of holding frame, described holding frame is connected with overturning oil cylinder, and described jaw is connected with clamping oil cylinder.
Described door frame lifting mechanism is arranged on the front end of power machine by connecting panel.
Described door frame lifting mechanism is provided with door frame guide groove, door frame elevating ram and conduction chain, and described turnover bracket is arranged among door frame guide groove by guide wheel, drives conduction chain to pull turnover bracket up-and-down movement by door frame elevating ram.
Described power machine is made up of vehicle frame, traveling gear, operator's compartment and control system, and large tractor chassis can be adopted to make, and ground gap is greater than 400mm, and uses Eight characters line nonskid tire.
Described jaw is the arcuate structure bent downwards.
The holding frame of clamping switching mechanism is fixed on turnover bracket by upset bearing pin, and overturning oil cylinder rear end bearing pin is rotatably connected on turnover bracket, and front end is rotatably connected on holding frame, drives holding frame to rotate up and down.
Clamping oil cylinder rear end thereof is connected on holding frame, and front end bearing pin is hinged with jaw, promotes jaw and rotates up and down, realize the clamping of jaw and unclamp under the hydraulic-driven clamping oil cylinder.
Power is flowed to walking machine by V-belt by power machine, and drive car load motion, turning to of fork truck is controlled by bearing circle.Power machine drives hydraulic pump works simultaneously, high-pressure oil flow oil is transported to each hydraulic ram through transport pipe, multi-way control valve, provides hydraulic work system power.
Operation process is as follows: door frame elevating ram, the piston rod of clamping oil cylinder is regained, turnover bracket reduces as far as possible, jaw is opened, handle multiway valve control stalk, make the piston cylinder of overturning oil cylinder project forwardly to maintenance level bottom prong to incline slightly before, start before holding frame is aimed at the agricultural crop straw of tiling or stacking by fork truck and push away, pile with until stalk or sugarcane the piston rod that holding frame (crotch) clamps afterwards oil cylinder to stretch out, jaw clamping stalk, operated door is erected and is risen control handle and rise by turnover bracket and rise to correct position, unclamp jaw, the piston rod of overturning oil cylinder stretches out, realize stalk to tumble discharging, complete a working cycle.
The beneficial effects of the utility model are:
The utility model provides a kind of farm machinery storing up utilization and sugarcane entrucking carrying for stalk,
Replace pitching dress by hand by machinery fork dress mode, operating efficiency improves more than ten times, and making large-scale stalk store up utilization becomes possibility, and the problem of environmental pollution caused for solving stalk on-site incineration have found the approach of a practicable.
Fork truck of the present utility model can realize cross-country function, can operation smoothly between the poor sugarcane field of state of ground, reduces the labour intensity of harvesting sugarcane work, achieve that sugarcane is collected, carrying, entrucking a tractor serves several purposes.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further elaboration the utility model, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.
As Figure 1-3, a kind of agricultural straw fork truck, comprises power machine 1 part of fork truck, and also comprise door frame lifting mechanism 2 and clamping switching mechanism 3, clamping switching mechanism 3 is arranged on door frame lifting mechanism 2, and door frame lifting mechanism 2 is arranged on power machine 1; Clamping switching mechanism 3 is made up of turnover bracket 36, holding frame 33, jaw 31, prong 35, overturning oil cylinder 34 and clamping oil cylinder 32, turnover bracket 36 is arranged on door frame lifting mechanism 2 as lifting part, holding frame 33 is arranged on turnover bracket 36 by rotating shaft, jaw 31 is rotationally connected by rotating shaft and holding frame 33 upper end, prong 35 is connected to the lower end of holding frame 33, holding frame 33 is connected with overturning oil cylinder 34, and jaw 31 is connected with clamping oil cylinder 32.Power machine 1 is made up of vehicle frame, traveling gear 13, operator's compartment 11 and control system 12, and adopt large tractor chassis to make, ground gap is greater than 400mm, and uses Eight characters line nonskid tire.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets is only preference of the present utility model; be not used for limiting the utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
