Description
Technical field
The utility model relates to the combine field, particularly a kind of small-sized caterpillar belt formula combine that is used for paddy-field-working.
Background technology
The running gear of existing baby combine comprises two kinds of wheeled and crawler types, the baby combine of these two kinds of running gears can both adapt to the paddy rice harvesting operation of doing the field, but when being used for paddy field harvesting operation, wheeled combine will produce skidding, can not walk forward, can't gather in operation normally.Also once there was left and right sidesing driving wheel to repack impeller into the combine of running gear system, driving this combine with the blade of impeller walks in the paddy field, but this combine can drive a large amount of mud when impeller rotates splashes, mud layer in the paddy field digs dell, destroy the soil horizon in paddy field, the mud that splashes simultaneously can splash on operating personnel's the body again, causes the operator can't normal running, so the peasant is unwilling to use the combine of this structure.And the blade size Control difficulty of this impeller, the too little combine that can not drive is advanced, and damage is very easy to fracture too greatly again.Though the combine of cterpillar drive can be in the shallow mud layer shallow water Tanaka operation of walking, for the dark mud layer deep water field of retaining throughout the year, the combining chance of cterpillar drive equally can not normal operation over head and ears in the paddy field.The inventor is at a kind of combine ZL 200920206735.4 that is used for the paddy field of the patent of first to file, a kind of plate that paddles that is provided with on crawler belt is disclosed, the described plate that paddles is dismountable to be fixed on the crawler belt, the plate face of plate of paddling is vertical with crawler belt or tilt, this patented technology scheme, increase frictional force with the deep water field by the plate that paddles, thereby track combine is advanced normally, but actual use is found, it still exists some following problems: 1, the plate that paddles is installed on the crawler belt, because the plate that paddles is a veneer, only there is support in the place that is connected with crawler belt, bottom, when stressed than greatly the time, the damage that is very easy to fracture influences normal harvesting work; 2, because the muddy water in paddy field has certain viscosity, baby combine is walked forward and muddy water need be arranged, and therefore baby combine generation nose phenomenon usually takes place, and causes the harvesting and threshing apparatus harvesting less than paddy rice.
The utility model content
The technical problems to be solved in the utility model is: providing a kind of can normally walk in the paddy field, and is difficult for the small-sized caterpillar belt formula combine of nose.
In order to solve the problems of the technologies described above, the utility model provides a kind of paddy field small-sized caterpillar belt formula combine, include engine, the speed change gear that has output shaft, ship type support and harvesting and threshing apparatus, the left and right sides of ship type support is installed crawler unit respectively, the driving wheel of crawler unit is connected with the output shaft of speed change gear, some plates that paddle are installed on the crawler belt of described crawler unit, paddle and be provided with stiffener between plate and crawler belt, described ship type pedestal rear portion is provided with the anti-gripper shoe of sticking up, an anti-end that sticks up gripper shoe is hinged on the ship type pedestal, and the other end is connected to the top of ship type pedestal hinged place by support bar
Adopt the paddy field of technique scheme to have following advantage: 1 with small-sized caterpillar belt formula combine, owing on the crawler belt of crawler unit some plates that paddle are installed, paddle and be provided with stiffener between plate and crawler belt, the plate that paddles is reinforced plate and supports from the rear, the plate that paddles is subjected to can not fractureing behind the muddy water resistance, can walk normally in the paddy field; 2, because ship type pedestal rear portion is provided with the anti-gripper shoe of sticking up, an anti-end that sticks up gripper shoe is hinged on the ship type pedestal, the other end is connected to the top of ship type pedestal hinged place by support bar, anti-stick up the length that gripper shoe has been equivalent to extend pedestal, anti-ly stick up gripper shoe and have certain width, anti-sticking up on the muddy water that gripper shoe can be supported on the paddy field, overcome the strength that combine upwarps, prevent the generation of combine nose situation.
As preferred version, if considering the stiffener and the plate employing of paddling is rigidly connected, in the crawler belt rotating process, when particularly crawler belt was crooked, the generation of the very easy place's stress destruction that is rigidly connected considered that simultaneously combine is when hard place is worn walking, the phenomenon that the plate that may paddle fractures, therefore to be the hinge shape hinged for described stiffener and the plate that paddles, and the bottom of the stiffener and the plate that paddles is provided with grab, and crawler belt is provided with the hole clipping that matches with grab.
As preferred version, consider stiffener and the grab of plate of paddling may be deviate from the hole clipping from crawler belt, also be provided with the latch or the bolt that prevent that grab from deviating from the described stiffener.
As preferred version, for the power of paddling of the plate that guarantees to paddle, guarantee the support strength of stiffener simultaneously, the described angle that paddles between plate and the stiffener is 20～60 °.
As preferred version, consider the optimal effectiveness of actual use, limiting the described angle that paddles between plate and the stiffener is 30 °.
The utility model is described in further detail below in conjunction with drawings and Examples.
