Abstract
The utility model relates to a rotary tillage rake provided with a gear box assembly, a host machine rack, a hanging rack, a pressing cylinder, a knife shaft assembly and an adjusting rod assembly. The utility model is characterized in that in a plurality of knife disks on a transmission shaft of the knife shaft assembly, the knife head of one knife blade on every knife disk and the knife head of one knife blade on other knife disks are helically distributed, and accordingly, the operation resistance is reduced; simultaneously, the pressing cylinder is connected with the host machine rack by the adjusting rod assembly in order to adjust the tillage depth and the soil packing degree. The utility model completes the finishing operation before sowing at one time by cutting, throwing, striking, crumbling and pressing soil, and has the characteristics of high tillage efficiency, low cost, etc.
Description
The utility model relates to a kind of tillage implement that is driven by tractor motive power output shaft, particularly a kind of Rotary tillage rake.
At present, existing rotary tillage facility, the tulwar that is adopted (blade) soil-entering resistance is big, and power consumption is big, and the oil consumption height can only make soil loosening, can not reach the displacement of levels soil, and vegetation coverage is low, the one-stop operation before can not realizing sowing.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of Rotary tillage rake is provided, and it can make operation resistance reduce, and integrates cultivated simultaneously, harrows, suppresses, and can improve farming efficient, reduces the farming cost.
The purpose of this utility model realizes by following technical proposals:
Rotary tillage rake has gearbox assembly, mainframe, hanger bracket, the suppression tube, the cutter shaft assembly, wherein, the cutter shaft assembly is by power transmission shaft, cutterhead, blade is formed, several cutterheads are installed on the power transmission shaft, several blades are installed on each cutterhead, blade is L-shaped, the cutter head position of adjacent two blades is relative on each cutterhead, its technical scheme be on the power transmission shaft in several cutterheads the cutter head of the cutter head of a blade on each cutterhead and a blade on other cutterhead in the shape of a spiral line distribute, thereby the cutter head of several blades distributes by several helixes that equal a blade number on the cutterhead; The suppression tube is connected with mainframe by the adjusting rod assembly, described adjusting rod assembly is made up of support, screw rod, locking device, can be affixed by locking device and mainframe around the support that mainframe rotates, the following free end of support is equipped with the suppression tube that can rotate, the last free end of support and an end of screw rod are hinged, and the other end of screw rod and the extension of mainframe are hinged.
In the technique scheme, 12 cutterheads are installed on the power transmission shaft altogether, 4 blades are installed on each cutterhead, on the power transmission shaft in 12 cutterheads the cutter head of the cutter head of a blade on each cutterhead and a blade on other cutterhead be and revolve helical and distribute, thereby the cutter head of 4 blades distributes by 4 helixes.Locking device be located at the support both sides, be positioned at two bolts of support around mainframe run-on point position.The extension of mainframe is the hanger bracket affixed with mainframe.
The utility model is owing to the cutter head line distribution in the shape of a spiral of the cutter head and a blade on other cutterhead of a blade on each cutterhead in several cutterheads on the described power transmission shaft, thereby the cutter head of several blades distributes by several helixes that equal a blade number on the cutterhead.The distribution of blade on cutterhead is more reasonable like this, thereby has reduced operation resistance, has improved operating efficiency, has reduced oil consumption; The suppression tube is connected with mainframe by the adjusting rod assembly simultaneously, in order to the adjusting tilth with to the soil packing degree.Tilth of the present utility model is by the screw rod on the adjusting adjusting rod assembly, and change hack suppression tube is realized with the relative position of cutter head.Transfer short this screw rod, the suppression tube raises, and the tilth of blade increases; Transfer long this screw rod, the position of suppression tube reduces, and blade is subjected to suppressing the support of tube, and tilth is shoaled, and then the hack of suppression tube and compaction increase.The utility model is rotatablely moving and the compound motion that advances of facility with the cutter shaft cutter, to uncultivated land with ploughed and carried out operation, by to the cutting of soil, throw, hit, hack and suppression, once finish the preceding finishing operation of sowing, thereby reduced the farming number of times, reduce the farming cost, increased economic benefit.Go up pine, real, vegetation coverage is high, table is thin preferential species bed down and obtain one.
The utility model is described in further detail below in conjunction with embodiment:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
Fig. 3 is the structural representation of cutterhead.
Fig. 4, Fig. 5, Fig. 6 are respectively front view, left view, the vertical view of blade.
Fig. 7 is the arrangement expanded view (the A direction is the direction of advance of Rotary tillage rake) of blade in the utility model.
As Fig. 1, Fig. 2, shown in Figure 3, the utlity model has gearbox assembly 2, mainframe 3, hanger bracket 1, suppression tube 10, cutter shaft assembly, adjusting rod assembly, wherein, the cutter shaft assembly by power transmission shaft (it be divided into power transmission shaft right half part 4 and power transmission shaft left-half 4 '), cutterhead 5 and 5 ', blade 6 and 6 ' form, power transmission shaft right half part 4 and power transmission shaft left-half 4 ' on be separately installed with 6 cutterheads 5 and 5 ', be equipped with on each cutterhead 4 blades 6 or 6 '.As shown in Figure 3, circular hole 5a, 5b, 5c, 5d are hole, installation site such as Fig. 4, Fig. 5, shown in Figure 6 of 4 blades on the cutterhead, and blade is L-shaped, and it has cutter hub 6a and cutter head 6b, the angle of cutter hub and cutter head is between 90 °-120 °, and best angle is about 100 °.The cutter head position of adjacent two blades is relative on each cutterhead, and one of them stretches to the left side cutter head of promptly adjacent two blades, and another stretches to the right side.As Fig. 1, Fig. 2, shown in Figure 7, on the power transmission shaft in 12 cutterheads the cutter head of the cutter head of a blade on each cutterhead and a blade on other cutterhead be and revolve helical and distribute, thereby the cutter head of 4 blades distributes by 4 helixes.Suppression tube 10 is connected with mainframe 3 by the adjusting rod assembly, described adjusting rod assembly is made up of support 8, screw rod 7, locking device 9, can be affixed by locking device 9 and mainframe 3 around the support 8 that mainframe rotates, the following free end of support 8 is equipped with the suppression tube 10 that can rotate, the last free end of support 8 and an end of screw rod 7 are hinged, and the extension of the other end of screw rod 7 and mainframe 3 is hinged.Locking device 9 for be located at the support both sides, be positioned at two bolts of support around mainframe run-on point position.The extension of mainframe 3 is the hanger bracket 1 affixed with mainframe.The utility model is driven by tractor motive power output shaft, drives to one of gearbox assembly idler gear via universal joint, reaches power transmission shaft via idler gear, and this is a prior art.
