Abstract
The utility model provides a stalk clamping mechanism of a corn ear picking test bed. The stalk clamping mechanism comprises conveying chain cross beams, a stalk sleeve, a stalk fastening bolt, fixed press plates, V-shaped movable press plates, press plate fastening bolts, a mounting base and base fastening bolts. With the adoption of the stalk clamping mechanism, corn plants can be clamped conveniently and stably, and stalk sleeves with different inner diameters can be replaced quickly to meet clamping requirements of the corn plants with different diameters; adjustment can be performed according to the plant distance of corn, so that the actual state of the field operation can be well simulated; meanwhile, the problems that corn stalks are clamped unstably and prone to lodging during conveying due to the fact that the corn stalks are high in center of gravity are solved.
Description
(1) technical field
The present invention relates to a kind of corn picker testing stand stalk clamping device, belong to test Aided Machine.
(2) background technology
Corn is the main cereal crops of China, is also important food, feed and the raw material of industry.In the annual cultivated area of China's corn, up to 2,697 ten thousand hectares, Maize Production has wide influence to the whole national economic development of China and social stability.But there is the reasons such as damage, percent of loss height in China's corn harvesting machine at present, and mechanical harvest degree is low.The development of accelerating maize harvesting mechanization is the task of top priority of China's corn planting industry.
In recent years, each colleges and universities and R&D institution have designed numerous dissimilar corn picker testing stands, these testing stands have been created good laboratory test condition, and the virtual condition of energy simulate farm work, for the research and development of corn mechanical harvest technology and equipment provide technical support.But because maize straw center of gravity is high, clamping is unstable, easily lodging in course of conveying.
(3) summary of the invention
In order to address the above problem, the invention provides a kind of corn picker testing stand stalk clamping device, can facilitate firm clamping milpa, and the stalk sleeve pipe of fast changeable different inner diameters, to meet the clamping requirement of milpa of different-diameter, and can easily adjust corn plants distance.
A kind of corn picker testing stand stalk clamping device, comprises carrier chain crossbeam, stalk sleeve pipe, stalk fastening bolt, fixation clip, V-type movable pressing board, pressing plate fastening bolt, mounting seat and base fastening bolt.
Described stalk sleeve pipe is one section of hollow circular-tube, and stalk sleeve pipe top is provided with the screw being used in conjunction with stalk fastening bolt; The diameter of stalk sleeve pipe can be according to the size setting of different milpa diameters, for clamping the milpa of different-diameter.Stalk casing length is greater than 10cm and is less than the setting height(from bottom) of carrier chain crossbeam apart from ground, can not touch ground while making stalk sleeve pipe forward transport platform below to carrier chain.When work, maize straw is vertically put into stalk sleeve pipe, stalk sleeve pipe plays certain supporting function to milpa, tightens stalk fastening bolt, milpa is fixed, while preventing from testing because of the vibrations of machine make maize straw tilt or lodging.
Described mounting seat bottom is provided with U-shaped groove, and U-shaped groove card is placed on carrier chain crossbeam, and U-shaped trench bottom is provided with screw, by bolt, mounting seat is fixedly mounted on carrier chain crossbeam.
Described both sides, mounting seat top (being U-shaped groove back) are respectively welded with a fixation clip, all and two piece fixation clips vertical with the mounting seat upper surface installations that is parallel to each other of two fixation clips; The centre position of one side fixation clip up and down vertical two be provided with screwed hole; Screwed hole is for being used in conjunction with fastening fixation clip with pressing plate fastening bolt.
The fixation clip inner side that is provided with screwed hole is provided with a V-type movable pressing board, and stalk sleeve pipe is positioned in the middle of V-type movable pressing board; On V-type movable pressing board, be vertically provided with two screwed holes on fixation clip and distinguish two screws that corresponding diameter is the same; Use pressing plate fastening bolt by the pressure of V-type pressing plate, stalk sleeve pipe to be pressed on opposite side fixation clip, prevent that stalk sleeve pipe from moving, can change easily stalk sleeve pipe according to stalk diameter on the other hand.
In the present invention, stalk loop bar adopts unfixed mode to be connected with mounting seat, can conveniently be changed according to stalk unit's diameter; Meanwhile, carrier chain crossbeam position can be according to the plant of corn apart from adjusting, and virtual condition that can simulate farm work, for the research and development of corn mechanical harvest technology and equipment provide technical support.Meanwhile, the setting of fixation clip, V-type movable pressing board and pressing plate fastening bolt, has solved because maize straw center of gravity is high, and clamping is unstable, the problem easily lodging in course of conveying.

(5) embodiment
The U-shaped groove of mounting seat is stuck in carrier chain crossbeam top, and mounting seat is alignd with the hole on crossbeam, uses bolted.Carrier chain crossbeam two ends are arranged on carrier chain with bolt, and installation site can be adjusted as required.Carrier chain can be arranged in transport platform by sprocket wheel according to prior art, and the cycle rotation of carrier chain drives carrier chain crossbeam to rotate; The power of carrier chain can be provided by motor; Fixation clip is welded on (the U-shaped back side) on mounting seat bottom surface, a side fixation clip punching.V-type movable pressing board is fixed on the inner side of a side fixation clip, is vertically provided with up and down two screwed holes that are used in conjunction with pressing plate fastening bolt on this side fixation clip simultaneously; Stalk sleeve pipe be vertically placed on V-type movable pressing board and and V-type be relatively fixed between pressing plate, thereby by tighten pressing plate fastening bolt promote movable pressing board stalk sleeve pipe is pressed on fixation clip.Stalk sleeve pipe middle and upper part sidewall is provided with stalk fastening bolt, and maize straw is put into after stalk sleeve pipe, tightens stalk fastening bolt, can prevent from maize straw course of conveying, inclining askew or lodging.
When work, first adjust the installation site of carrier chain crossbeam on carrier chain by requirement of experiment, in order to simulate more really field actual conditions, distance between carrier chain crossbeam is equated with the plant distance of this corn, then by mounting seat, fixation clip, stalk sleeve pipe order are installed (test milpa can be divided into several groups by stalk diameter, the stalk sleeve pipe that choosing adapts with it).In the utility model, stalk sleeve pipe does not adopt and mounting seat fixed installation, is made as and the mobilizable installation of mounting seat, is convenient to use instead at any time according to the size of milpa.Unclamp stalk sleeve bolt, individual plant milpa is inserted to stalk sleeve pipe, tighten stalk sleeve bolt.Corn picker is complete, and etc. maize straw wraparound transport platform when top after harvesting, carrier chain stops operating, and unclamps stalk fastening bolt, the milpa more renewing.If maize straw external diameter and casing inner diameter differ larger, unclamp pressing plate fastening bolt, change stalk sleeve pipe.
Protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in, the simple change of the technical scheme that can obtain apparently or equivalence replace all fall within the scope of protection of the present invention.
