Description

Rear-mounted root harvester

The utility model relates to a kind of agricultural machinery, particularly a kind of root harvester.

Root harvester of the prior art, owing to adopt front positioning type structure and fixed plough shovel, there are the following problems to make it:

1, power consumption is big, inefficiency, the four-wheel tractor that adapted 15kw is following.

2, wherein tilling depth in 18cm, though can gather in the crops the more shallow crops of rhizome such as peanut, garlic to a certain extent, but can not solve peanut and twine seedling, peanut, the problem that the garlic breakage rate is high surpass 18cm to rhizome degree of depth such as sweet potato, potato, the root of herbaceous peony, balloonflower root, radix salviae miltiorrhizaes and just can not gather in the crops near the crops of 40cm.Chinese patent ZL99252435.0 number, though be rear-mounted structure, solved the problems referred to above basically, its structure is still complicated, and efficient is still not high enough, is still had certain breakage rate by harvested product.

The purpose of this utility model will provide a kind of rhizome degree of depth of gathering in the crops near 40cm exactly, and wide accommodation is simple in structure, reliable operation and efficient height, the root harvester that breakage rate is low.

The purpose of this utility model is achieved through the following technical solutions.

The utility model is a kind of rear-mounted root harvester, and its design feature is:

A, adopt rearmounted frame, the bottom that plough shovel frame, plough shovel frame are set on the frame is provided with the plough shovel, and they can moving ahead and do swing with frame.

B, employing cam drive mechanism, drive link one end is hinged on the top of plough shovel frame, and other end shovel is connected on the cam.

C, be provided with the gauge wheel of adjustment height in the bottom of frame or the plough heel curre be set at the rear lower of plough shovel.

The utility model has the advantages that: be suitable for the results of multiple tubers crops, adapt to widely, the degree of depth of rhizome results is near 40cm, and more old-fashioned reaping machine is energy-conservation 30%, can use with the four-wheel tractor of various power; Can to gather in the crops rhizomes such as red taro, potato, the root of herbaceous peony, balloonflower root darker with the maximum supporting use of tractor with small four wheels of present rural area owning amount, near the crops of 40cm, more can gather in the crops and the problem that is burdened with can effectively solve harvesting peanut the time for the more shallow crops of rhizomes such as peanut, garlic.This machine is simple in structure, reliable operation and efficient height, and breakage rate is low during harvesting crops.Solved the darker long-term manual problem of gathering in the crops of crops of these rhizomes, it is high so that the problem of bad use has realized the mechanization of root crop results to have solved more shallow crop machine time receiving breakage rate.Realized the high-quality, efficient, low-cost of results.

This is described in further detail utility model below in conjunction with drawings and Examples:

Embodiment 1:

Referring to Fig. 1, present embodiment is rear-mounted structure.As shown in Figure 1, adopt rearmounted frame, this frame can be frame, is provided with on the frame to move ahead the plough shovel 3 of the plough shovel frame 2 of doing swing and plough shovel frame bottom on described plough shovel 3 with frame, and its both sides are side plough shovel 4, and the underframe of bottom is anterior to be plough shovel 5 down.The front and rear part is provided with grizzly bar.The front portion of following plough shovel can be provided with plough spear 7.The plough spear adopts the claw-like structure.Plough spear pawl is long to be 50-80cm, and centre-to-centre spacing is 60-85mm between pawl.Plough shovel both sides, frame bottom are side plough shovel 4.Grizzly bar 6 is long and both sides formation paliform along the bottom, and side plough shovel is a linear structure.

Adopt cam drive mechanism, drive link 8 one ends are hinged on the top of plough shovel shovel frame 2, and the other end is hinged on the cam 9; The articulated position of drive link 8 on plough shovel frame 2 is adjustable up and down.

Be provided with adjustable for height gauge wheel 10 in the bottom of described frame 1, gauge wheel 10 can be a pair of road wheel that places the frame front end, also can be arranged on two pairs of road wheels of both sides, frame front and back.

Embodiment 2

With reference to Fig. 2, Fig. 3: present embodiment adopts rearmounted frame 1, and above-mentioned plough shovel frame 2, plough shovel 3 are set on the frame.

Side plough shovel 4 in described plough shovel both sides, frame bottom is the bending-type side plough shovel, the middle bent part of two side plough shovels all is not orthogonal to by results surface, soil, this crooked angle is 20 °～80 °, best 60 °～78 ° rear portions at the bending-type side plough shovel are equipped with respectively one of left and right sides soil guiding board 12, and two soil guiding boards are combined to form, and to cross Tu Kou be pre-large post-small, but plate 13 is held together in postpone on the adjusting rod of gauge wheel 10.Embodiment 3: as shown in Figure 4: this structure is provided with plough heel curre 11 for the rear lower at the plough shovel, and the plough heel curre can replace gauge wheel.Its frame such as Fig. 2 mode have adopted tiltedly curved formula, and working method is the same.

Embodiment 4:

Referring to Fig. 5, as shown in Figure 5, this structure adopts a kind of more simple frame, and this frame is oblique flat, and its working method as above.

Clutch 14 between the utility model and engine power transmit, promptly the clutch that installs on little four-wheel side power take-off is a zigzag structure, the number of teeth is between 2～20.Clutch in conjunction with the time, the rotary power of power take-off can transmit by zigzag clutch tooth.

The utility model course of work is as follows: when complete machine is on the way walked and during headland turn, drive frame and rack-mounted plough shovel frame is mentioned by the hydraulic lifting arm on the four-wheel tractor, make the pears shovel that certain altitude overhead be arranged, be convenient to walking.In the field as the time, stir clutch handle, make the clutch combination, pass through transmission mechanism, the outputting power of tractor is passed to main shaft, by cam and drive link this is rotatablely moved and change reciprocating motion into, plough shovels frame and the plough shovel is done the swing campaign with respect to the tractor direction of advance thereby drive.Meanwhile, because the swing crops rhizome and the combining closely of soil of grizzly bar are got loose by vibration, hand is easy to pick up the crops rhizome from soil surface, thereby finishes the process that the crops rhizome is gathered in the crops from soil.

Plough shovel of the present utility model is installed on the plough shovel frame movably, when gathering in the crops general root crop, and the side of available linear structure plough presentation plough shovel; When the crop of easy generations " twining seedling " such as results peanut, the side plough shovel formula plough shovel of available bending, this bending Tu Kou excessively that each soil guiding board of one is combined to form about the rear portion again is pre-large post-small, peanut seedling of being gathered in the crops under the acting in conjunction of 2 soil guiding boards again in the side, middle part of 2 side plough shovels and peanut are clipped among the hack middle part that can be smoothly can not be hung in left and right sides side plough shovel by plough shovel and soil guiding board, have avoided hanging the generation of peanut seedling and obstruction.Since after hold together plate effect, peanut seedling and related peanut thereof are drawn on narrower soil surface to be convenient to pick up, when working next fabric width simultaneously, dilatory wheel does not roll and has received peanut.
