Detailed Description
As shown in fig. 1 and fig. 2, the present invention relates to a fat leg assembly with fracture protection function, which comprises a fat leg body 1 and a fat leg fixing mechanism.
The fertilizer leg body 1 comprises a vertical rod 101 and a ditching ploughshare 102 connected to the lower end of the vertical rod 101, a fertilizer applying pipe 8 connected with the ditching ploughshare 102 is arranged behind the vertical rod 101, and the fertilizer applying pipe 8 is used for conveying fertilizer into a groove formed by the ditching ploughshare 102. The front of the vertical rod 101 is rotatably provided with a grass poking wheel 3, the grass poking wheel 3 is a cylindrical roller, the axial direction of the grass poking wheel 3 is consistent with the length direction of the vertical rod 101, the lower end of the grass poking wheel 3 is connected to the ditching ploughshare 102, and the upper end of the grass poking wheel 3 is connected with a baffle 9 transversely fixed on the vertical rod 101. When the grass poking wheel 3 receives the advancing resistance formed by straws, weeds and the like, the straw poking wheel can prevent the straws, the weeds and the like from winding the fertilizer leg body 1 through the rotation in the horizontal direction, and further the resistance received by the fertilizer leg body 1 is reduced. It should be noted that the "front" of the present invention is the direction of the ditching plow 102 in the ditching process, otherwise, it is the "rear".
The fertilizer leg fixing mechanism comprises a connecting piece 2 for fixing the fertilizer leg body 1 and a connecting bolt 5 for installing the connecting piece 2 on the frame 7. The frame 7 is connected on the tractor, is hauled the frame 7 by the tractor and in order to provide the power of marcing to fertile leg body 1, drives fertile leg body 1 forward motion and fertilize the operation.
Connecting bolt 5 is the U-shaped bolt, and in order to keep the fastness fixed to fertile leg subassembly, the U-shaped bolt sets up to two, two U-shaped bolt parallel distribution, the U-shaped section of U-shaped bolt is used for connecting in frame 7, and the straightway of U-shaped bolt passes and connects on connecting piece 2 after the through-hole of seting up on connecting piece 2, realizes being connected of frame 7 and connecting piece 2 through the nut of the U-shaped bolt tip of screwing.
The connecting piece 2 comprises a fixed base plate 201 and two clamping plates 202 arranged on the fixed base plate 201 at intervals, the fixed base plate 201 is a rectangular plate, and the fixed base plate 201 is fixedly connected with the frame 7 through the U-shaped bolts. Two clamping plates 202 arranged on the fixed bottom plate 201 are distributed in parallel, and the two clamping plates 202 are all perpendicular to the fixed bottom plate 201. A vertical clamping space for clamping the fertilizer leg body 1 is formed between the two clamping plates 202, and the vertical rod 101 of the fertilizer leg body 1 is positioned in the clamping space. In addition, two L-shaped clamping plates may be disposed on the frame 7 to form the clamping space, the two L-shaped clamping plates are disposed on the back, each L-shaped clamping plate is disposed with one of the side plates as a fixing bottom plate 201, at this time, the fixing bottom plates 201 are two on both sides of the vertical rod 101 of the fertilizer leg body 1, and the fixing bottom plates 201 are also fixedly connected to the frame 7 through the U-shaped bolts.
The two clamping plates 202 are connected with the fertilizer leg body 1 through a fracture protection mechanism, as shown in fig. 2 and fig. 3, the fracture protection mechanism comprises a rotating shaft 4 which is rotatably connected with the clamping plates 202 and the fertilizer leg body 1 and a fastener 6 which can fasten the two clamping plates 202, the fastener 6 is positioned above the rotating shaft 4, and the fastener 6 can be fractured to protect the fertilizer leg body 1 when the resistance of the lower end of the fertilizer leg body 1 reaches the limit. The fastening members 6 are bolts, and the bolts may be provided in plural and distributed at intervals in the height direction of the clamping plate 202, and the number of the bolts in this embodiment is three. In order to enable the bolts to be broken when the resistance at the lower end of the fertilizer leg body 1 reaches a certain degree, the selected bolts are bolts with low strength, and the bolts are only required to be broken in advance before the fertilizer leg body 1 is broken or bent. The rotating shaft 4 is rotatably connected with the clamping plate 202 and the fertilizer leg body 1 so as to prevent the fertilizer leg body 1 from falling off the frame 7 after the fastener 6 is broken. When the fixed bottom plate 201 is a rectangular plate provided with two clamping plates 202, in order to avoid the fixed bottom plate 201 from interfering with the rotation of the fertilizer leg body 1, the lower edge of the fixed bottom plate 201 is higher than the position of the rotating shaft 4 on the clamping plates 202.
The utility model discloses when using, fertile leg body 1 moves forward under the tractive effect of tractor, its lower extreme advances because the effect of resistance is restricted, makes fertile leg body 1 take place along 4 pivoted trends of pivot, exerts pressure to fastener 6 by fertile upper end of leg body 1, breaks when fastener 6 receives pressure and surpasss its limit value that breaks and takes place promptly, fertile leg body 1 rotates along pivot 4, forms the protection in order to avoid it to take place to buckle or break fertile leg body 1.
