Abstract

The utility model relates to agricultural tillage land operating machinery, in particular to a reciprocating shovel type tillage machine. The reciprocating shovel type tillage machine comprises a machine frame, a speed changing box, depth limiting wheels, press wheels and shovel blades, wherein the speed changing box is installed on the machine frame, the depth limiting wheels are installed on the front end of the machine frame through a depth liming wheel frame, and the press wheels and the shovel blades are installed on the rear end of the machine frame. The output end of the speed changing box is in driving connection with a cam shaft which is transversely installed on the machine frame, two cams are symmetrically installed on the cam shaft, the machine frame is provided with two sliding rods through guiding grooves, the upper ends of the sliding rods respectively correspond to the two cams, each sliding rod is inclined in the angle of 45 degrees to 90 degrees relative to the ground and towards the heading direction, and the shovel blades are installed at the lower ends of the sliding rods. When the reciprocating shovel type tillage machine tillage machine goes forwards, the shovel blades form certain degrees with the ground to conduct reciprocating motion. Soil is cut, raised but not stirred, soil layers are not damaged, the purposes that the soil is loosened and the soil on the ploughing sole layer is cut are achieved, and the defect of damage to the soil layers in a current frequently-used mechanized tillage is overcome.

Description

Reciprocal shovel harvesting and tillage machine

Technical field

The utility model relates to agricultural and ploughs whole earth working machinery, particularly a kind of shovel harvesting and tillage machine.

Background technology

Because for a long time natural cause and irrational production and operating activities are on the rise the northeastern China water and soil loss, if in addition effectively control, the mollic of this trend continues black soil region will most ofly disappear.

The mechanized farming method that Northeast black earth area is commonly used now is to broadcast on the broken stubble ridging ridge, also there are some areas still to continue to use the flat expedient of tillage of turning over rear ridging of the eighties of last century formation sixties, the former finishes with stubble cutter, intertillage ridger and sower, the latter adopts plough, rake, pack roller, cultivating seeder to finish sowing, then divides with cultivator and wades out the ridge body 2～3 times.Above-mentioned two kinds of cultivated methods all need repeatedly operation, and will stir soil, destroy soil layer, and eliminated the covering on earth's surface, and easily causing the erosion of table folk song, broken stubble ridging commonly used is ploughed method, because of its tilling depth shallow (not enough 10cm), tillage pan is shoaled, impact is ventilated permeable and crop takes root growth.

The conservation tillage method of Demonstration And Extension since 2000; except the pattern that covers of returning crop stocks to the field is adopted in some areas; most areas are to adopt to stay the solid Deflection of (height) stubble; and the cropping pattern that has many areas to adopt (ridge) ditch (ridge) platform to replace; do not stir soil; do not upset topsoil, better keeping earth's surface root stubble vegetation is the target that conservation tillage is pursued.The utility model is exactly soil is manually cut in imitation with spade action; the soil tilting is not stirred; soil cutting shovel is extracted by the former road of direction of insertion substantially; namely to cut soil place reciprocating; reach chesson, cut tillage pan and do not stir soil; the effect that still keeps the topsoil increased surface covering realizes conservation tillage.

Summary of the invention

The purpose of this utility model is to propose a kind of novel reciprocal shovel harvesting and tillage machine, this harvesting and tillage machine is when advancing, make that perching knife and ground are angled to move reciprocatingly, cutting, tilting but do not stir soil, do not destroy soil layer, the purpose that reaches chesson, cuts the pears bottom is to overcome the defective of the destruction soil layer that mechanized farming method commonly used at present exists.

The reciprocal shovel harvesting and tillage machine of the utility model, comprise frame, be arranged on gearbox on the frame, be arranged on the gauge wheel of frame front end, the press wheel that is arranged on frame rear end, perching knife by the gauge wheel frame, output at described gearbox drives connection one camshaft that is horizontally set on the frame, be symmetrical arranged two cams at camshaft, by guide groove two upper ends are set and correspond respectively to two camshafts, be the tilt sliding bar at 45 °～90 ° of angles of forward direction with ground on described frame, the lower end of this sliding bar arranges described perching knife.

Described cam is dish type, is designed to simple harmonic motion, and lift is 230mm, the cam perching knife action twice that rotates a circle, and 135 ° at rise angle, 45 ° at backhaul angle, radius of cam base-circle is 115mm, the rise pressure angle is 30 °.

Described perching knife is trinacriform, and the open angle of each point of a knife is 60 °～78 °, and the basil is 12 °～15 °, the wide 150mm of perching knife.

When adopting the reciprocal shovel harvesting and tillage machine of the utility model to plough whole soil, perching knife and ground are angled to move reciprocatingly, cutting, tilting but do not stir soil, do not destroy soil layer, the purpose of reach chesson, cutting the pears bottom has effectively overcome the at present defective of the destruction soil layer of mechanized farming method existence commonly used.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the structure of the utility model harvesting and tillage machine.

With reference to Fig. 1,2, a kind of reciprocal shovel harvesting and tillage machine, comprise frame 4, be arranged on the gearbox 5 on the frame 4, be arranged on the gauge wheel 1 of frame 4 front ends by depth stop wheel carrier 2, be arranged on the press wheel 11 of frame 4 rear ends, perching knife 10, output at described gearbox 5 drives connection one camshaft 12 that is horizontally set on the frame, be symmetrical arranged two cams 6 at camshaft 12, on described frame 4, by guide groove two upper ends are set and correspond respectively to two camshafts 12, be the tilt sliding bar 7 at 45 °～90 ° of angles of forward direction with ground, the lower end of this sliding bar 7 arranges described perching knife 10.Be separately positioned on the self-return of the spring 8 realization sliding bars 7 on described frame 4 and the sliding bar 7 by two ends.

Described cam 6 is dish type, is designed to simple harmonic motion, and lift is 230mm, the cam perching knife action twice that rotates a circle, and 135 ° at rise angle, 45 ° at backhaul angle, radius of cam base-circle is 115mm, the rise pressure angle is 30 °.As shown in Figure 3, cam twice of the perching knife action that rotate a circle.

As shown in Figure 4, perching knife 10 is trinacriform, and the open angle of each point of a knife is 60 °～78 °, and the basil is 12 °～15 °, the wide 150mm of perching knife.
