Abstract

The utility model discloses a multi-function maize harvester suspended on the front bridge of a roller tractor to use. The multi-function maize harvester is composed of a maize harvesting device, a suspension device, an ear hoisting device, an actuating device and a granary. A set of straw cutter is installed at the lower part of the multi-function maize harvester and can return straw to fields when maize is harvested. A support bracket installed on the front bridge of the roller tractor and A big axle supporting on a bracket bearing are both the suspension point of the multi-function maize harvester and the lifting axial center, and undertakes the tasks of the power distribution driving axle of the whole multi-function maize harvester. Thus the multi-function maize harvester has advantages of simple and compact structure, small volume and flexible and convenient operation.

Description

Wheel type multi-function maize harvester mounted on front of tractor

The utility model relates to a kind of agricultural harvesting machine, a kind of more precisely maize harvesting machine that is suspended on the wheel tractor front portion.

The existing maize harvesting machine of China has two classes, one class is to change the maize harvesting machine that Maize harvesting machine forms in the place ahead of combined wheat harvester, another kind of is caterpillar tractor cable-stayed type maize harvesting machine, this two classes type volume and length are all very big, handle not enough maneuverability, the middle haggard of incompatibility hilly country, especially the latter, the tractor driving people also will take into account the place ahead and rear, even want to handle more than the people, and the former does not then have the function of returning crop stocks to the field, and influences the work effect.

The purpose of this utility model is in a kind of being applicable to of design, the small-sized corn reaping machine of haggard, cube little, maneuverability, and a people just can handle, and makes simultaneously again and returns crop stocks to the field.

Solution is to use the most extensively and maneuverability, is suitable for the maize harvesting machine of front portion suspension at the wheel tractor of middle fritter farmland operation, and adorns with the straw chopper in its underpart.

Accompanying drawing has provided specific embodiment of the utility model.

Fig. 1 is the utility model schematic appearance;

Fig. 2 is its plan structure kinematic scheme of holding concurrently.

This is to hang the multifunctional corn reaping machine before a kind of wheel tractor, by harvest corn device (1), suspension arrangement, fruit cluster delivering device (5), (20), transmission device and silo (8) are formed, the design concept of its suspension arrangement is, fixed support on the propons of wheel tractor (4) (2), be parallel in the hole on ground dress with bearing (25) at it, this bearing is supporting macro-axis (17), harvest corn device (1) is bearing on the macro-axis (17) by the bearing (22) that is located on its rear portion machine ear, in tractor (4) propons bottom one oil cylinder (9) is housed, this oil cylinder both can support harvest corn device (1), can drive it again serves as that axle is faced upward with macro-axis (17), like this, support and macro-axis are both as the fulcrum of harvesting apparatus (1), face upward the axle center that falls as it again, can adjust the upper-lower position of harvest corn device at work at any time, in adapting to, the characteristics of haggard ground injustice, on the other hand, in the transmission device of this machine, power take-off by tractor, by sprocket wheel (7) (6), universal coupling (3), bevel gear to (24) and sprocket wheel (23) driven by movable sprocket (19) with to harvest corn device (1), four drive sprockets (21) of fruit cluster delivering device (5) (20) and straw chopper (10) transferring power all are fixed on the macro-axis (17), like this, macro-axis (17) uses as a power distributing shaft again, not only simplified complete machine structure, strengthened transmission rigidity, it is long-pending to have reduced this body, also having solved harvest corn device (1) is the difficulty of axle transmission of power when facing upward with macro-axis (17), certainly, can't forget in this machine bottom and adorn with straw chopper (10) function so that these facility are returned crop stocks to the field.

For further reducing this machine assembly volume and doing counterweight to harvest corn device (1), to improve complete machine stability, do not influence the operating personnel visual field again simultaneously, silo (8) preferably is fixed on the tractor rear portion by support.

During work, tractor is aimed at milpa and is opened forward, and the staff can look at the working condition of reaping machine straight, be convenient to adjust rising and falling, shut down and reversing end for end of harvesting apparatus at any time according to landform, and easy to operate and maneuverability, a people can grasp the overall situation fully.In addition, lead device (11), rice-pulling chain (12) through holding up, draw stem roller (13) and pluck corn ear that fringe plate (14) taken without threshing, directly dial to screw feeder (20) by rice-pulling chain (12), and be sent to silo (8) through elevator (5), to adapt to China's wheat and corn regrowth hair growing area, the corn ear washiness of results, the characteristics of threshing immediately.

This maize harvesting machine is suspended on most popular wheel tractor front portion, and the adaptability of supporting type strong (all can be supporting) as type wheel tractors such as Shanghai-50, car pusher-55 and Dongfanghongs-75, so small investment, be convenient to promote, it is simple and compact for structure, volume is little, the operation maneuverability, handiness, extremely be fit to middle fritter farmland covered by contract and hilly and mountainous land use that China peasant contracts, and one-machine-multi-function, automaticity height will play positive role to improving the Tendency of Agricultural Machinery in China level.

Claims

1, hang the multifunctional corn reaping machine before a kind of wheel tractor, by harvest corn device (1), suspension arrangement, fruit cluster delivering device (5) (20), transmission device and silo (8) are formed, it is characterized in that, the structure of said suspension arrangement is such, fixed support on the propons of wheel tractor (4) (2), in it is parallel to the hole on ground, bearing (25) is housed, this bearing is supporting macro-axis (17), harvest corn device (1) is bearing on the macro-axis (17) by the bearing (22) that is located on its rear portion machine ear, supporting harvest corn device (1) being housed in the farm tractor front axle bottom and can driving it serve as the oil cylinder of spool facing upward (9) with macro-axis (17), in transmission device, by tractor motive power output shaft, by sprocket wheel (7) (6), universal coupling (3), bevel gear to (24) and sprocket wheel (23) driven by movable sprocket (19) with to harvest corn device (1), four drive sprockets (21) of fruit cluster delivering device (5) (20) and straw chopper (10) transferring power all are fixed on the macro-axis (17), in addition, in the bottom of harvest corn device one group of straw chopper (10) is housed also.
