Description
Technical Field
The utility model relates to the field of agricultural mechanical equipment, concretely relates to corn thresher.
Background
Along with the popularization of agricultural machinery automation, automatic equipment is also adopted in the threshing operation of large-scale corn crops, the corn threshing machine can complete operations such as threshing, screening and separating, loading and the like of corn at one time, the efficiency is high, the time and the labor are saved, the replacement of manpower is obvious in economic benefit, and the corn threshing machine is widely applied in China. The structure of the corn thresher in the prior art is shown in a notice number CN104737719A novel corn thresher, and is dragged by a power locomotive in the dragging and transferring processes; during actual threshing operation, the thresher needs to be continuously turned and moved in a short distance according to factors such as the stacking position, the feeding direction and the position of a loading locomotive, the thresher occupies a large space, the space factors of actual operation fields are different, the short-distance movement and turning of the tractor are troublesome, the operation difficulty is high, and the use is inconvenient.
Disclosure of Invention
The utility model provides a corn thresher with a self-walking device to solve the problems. The corn thresher is internally provided with a hydraulic motor, a needle swinging speed reducer, a driven chain wheel set and the like, and a drive axle is not needed, so that traction of an external traction locomotive is not needed, and the thresher is controlled to advance and retreat at a low speed and a short distance through a hydraulic valve.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a self-walking device fixing frame is fixed on a main support of the corn thresher, a hydraulic motor controlled by a hydraulic control valve is fixed on the self-walking device fixing frame, the hydraulic motor outputs kinetic energy to a swinging needle speed reducer through a first chain, the swinging needle speed reducer outputs the kinetic energy to a driven chain wheel set through a second chain, and a walking wheel fixed with the driven chain wheel set is driven to rotate.
The scheme of the utility model can also be:
the spline shaft part of the output end of the swinging needle speed reducer is provided with a separation claw.
The separation claw is controlled to be closed by a horizontal clamp controlled by a clutch device.
The hydraulic control valve is provided with an operating rod for controlling the oil inlet direction of the hydraulic motor.
The utility model discloses a corn thresher embeds from running gear, need not the external traction of pulling the locomotive, can realize that the thresher is at a slow speed short distance gos forward and retreat. The corn thresher with the built-in self-walking device is flexible in movement and turning, simple in control, high in practicability in actual operation occasions and high in market popularization value.
Drawings
FIG. 1 is a schematic view of a three-dimensional structure of a self-walking device of a corn thresher according to the present invention;
fig. 2 is a schematic view of the three-dimensional structure of the self-walking device of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, a corn thresher with a self-walking device is characterized in that a self-walking device fixing frame 3 is fixed on a main support 1 of the corn thresher, a hydraulic motor 7 controlled by a hydraulic control valve 4 is fixed on the self-walking device fixing frame 3, the hydraulic motor 7 outputs kinetic energy to a swing needle speed reducer 10 through a first chain 12, and the swing needle speed reducer 10 outputs the kinetic energy to a driven chain wheel set 11 through a second chain 13 to drive a walking wheel 2 fixed with the driven chain wheel set 11 to rotate.
The hydraulic motor 7 is connected with the hydraulic control valve 4 through a hydraulic oil pipe 6, an operating rod 16 is arranged on the hydraulic control valve 4 to control the oil inlet direction of the hydraulic motor 7 and finally control the travelling wheels 2 to move forwards or backwards.
The spline shaft part 14 at the output end of the pendulum needle speed reducer 10 is provided with a separation claw 9. The release pawl 9 is controlled to close by a horizontal gripper 8 controlled by a clutch device 15.
When the corn off-line machine moves for a long distance under the action of the tractor, the separating claw 9 is in a separating self-locking state, the walking wheel 2 drives the separating claw 9 to idle, and the hydraulic motor 7 and the swinging needle speed reducer 10 do not work at the moment. When the thresher is separated from the traction locomotive and needs to move and turn in a short distance, the thresher is started, the horizontal clamp 8 on the clutch device 15 is pushed and self-locked, and the separation claw 9 is engaged at the moment; meanwhile, an operating rod 16 of the hydraulic control valve 4 is pulled, the hydraulic motor 7 operates, the input end of the swinging needle speed reducer 10 is driven to operate through the first chain 12, and the output end of the swinging needle speed reducer 10 drives the driven chain wheel set 11 on the hub of the single-side walking wheel 2 to move through the second chain 13, so that the threshing machine can advance and retreat in a short distance.
The utility model discloses a corn thresher embeds from running gear, need not the external traction of pulling the locomotive, can realize that the thresher is at a slow speed short distance gos forward and retreat. The corn thresher with the built-in self-walking device is flexible in movement and turning, simple in control, high in practicability in actual operation occasions and high in market popularization value.
