Description

Technical Field

[0001] The utility model relates to the technical field of tillage plows, in particular to a tillage plow with adjustable width. Background Art

[0002] A plow is a farm implement for tilling the land. It was developed from a primitive double-edged triangular stone tool, and later consisted of a heavy blade at the end of a beam. It is usually tied to a group of livestock or motor vehicles that pull it, and can also be driven by manpower. It is used to break up soil clods and plow grooves to prepare for sowing. The plow is a soil tillage machine that has the main function of turning the soil, and also has the functions of loosening and breaking the soil. There are mainly moldboard plows, disc plows, rotary plows and other types. Ancient agricultural countries such as Egypt, China, and Persia had primitive wooden plows pulled by oxen three or four thousand years ago.

[0003] Publication No. CN205694062U discloses a distance-adjustable cotton field tillage plow, comprising a handle, a connecting rod, a middle plow arrow and two side plow arrows, wherein one end of the connecting rod is vertically fixed in the middle of the handle, and the other end of the connecting rod is detachably connected to the middle plow arrow through a bent adapter rod 1, and its end is also vertically fixedly connected with a front-to-back symmetrical horizontal cross bar, and the two ends of the horizontal cross bar are detachably connected to the two side plow arrows symmetrical on both sides through a bent adapter rod 2, and the adapter rod 2 is axially telescopically connected along the horizontal cross bar, and the middle plow arrow and the connecting rod are in a "J"-shaped structure, and the two side plow arrows and the middle plow arrow are in the same direction and are kept in front of the middle plow arrow, and the minimum distance between the two side plow arrows is less than or equal to the width of the middle plow arrow. The utility model has high soil loosening efficiency, is not easy to hurt cotton seedlings, has a light structure, is easy to carry, has low manufacturing cost, is simple to maintain, has low maintenance cost, saves time and effort, greatly improves production efficiency, and has an adjustable width of cultivated land, a wider range of applications, and is more flexible to use. Although the tillage plow can adjust the width of the cultivated land through the telescopic plow arrows on the left and right sides, so that the tillage plow can meet different needs of loosening the cultivated land, with a wider application range and better flexibility. However, when adjusting the spacing between the plow arrows on both sides, the operator needs to use tools to remove the fixing screws on both sides, and then install the screws after the adjustment is completed. The adjustment is not convenient enough and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a width-adjustable tillage plow, comprising a connecting rod, adjustment grooves are provided on both sides of the connecting rod, an adjusting rod is fixedly installed inside the adjusting groove, an adjustment hole is provided on the surface of the adjusting rod, a fixing block is fixedly installed on the surface of the connecting rod, a spring A is fixedly installed inside the fixing block, a baffle is fixedly installed on one end of the spring A close to the adjustment hole, a fixing bead is fixedly installed on one end of the baffle away from the spring A, and a plow sword is fixedly installed on one end of the adjusting rod away from the adjustment groove.

[0006] Preferably, the specifications of the adjustment rod and the adjustment slot match, and the adjustment rod and the adjustment slot are slidably connected. Here, by pulling the adjustment rods on the left and right sides, the spacing between the plow arrows on both sides can be adjusted, and the width of the cultivated land can be adjusted, so that the cultivated land plow can meet different needs of loosening the cultivated land, with a wider application range and better flexibility.

[0007] Preferably, the adjustment holes are evenly distributed on the surface of the adjustment rod, and the adjustment holes are snap-connected with the fixing beads. Here, the arrangement of multiple groups of adjustment holes allows the distance between the plowshares to have a wider range, and the fixing beads can cooperate with the adjustment holes to limit the adjustment rod.

[0008] Preferably, the baffle is slidably connected to the fixed block, and the sizes of the baffle and the fixed block match. Here, the baffle is subjected to pressure and slides into the fixed block, contacting the fixed bead to limit the connection hole.

[0009] Preferably, the end of the adjusting rod near the plow blade is provided with a connection slot, the end of the plow blade near the connection slot is fixedly installed with a connection block, a spring B is fixedly installed inside the connection block, a clamping block is fixedly installed at the end of the spring B away from the connection block, and a clamping slot is provided on one side of the adjusting rod near the clamping block. Here, plow blades of different sizes can be replaced, further expanding the application range of the plough.

[0010] Preferably, the specifications of the connecting block and the connecting groove match, and the connecting block and the connecting groove are slidably connected. Here, the plow blade and the adjusting rod can be fixed together.

[0011] Preferably, the clamp block is slidably connected to the connecting block, and the clamp block is snap-connected to the clamp slot. Here, the clamp block cooperates with the clamp slot to fix the plow blade and the adjustment rod together, and the clamp block is pressed downward to release the limit on the plow blade, so that plow blades of different sizes can be easily replaced.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by setting the adjusting groove, adjusting rod, adjusting hole, fixing bead, spring A, baffle and fixing block, when adjusting the spacing of the adjusting rod, the fixing bead and the adjusting hole can be used to fix the adjusting rod. When subjected to pressure, the fixing bead shrinks backward. After adjusting the appropriate spacing, the fixing bead pops out forward and is stuck in the adjusting hole, thereby fixing the adjusting rod, making it convenient for users to adjust the width of the plough.

[0014] 2. In the utility model, by setting the connecting block, the connecting groove, the spring B, the clamping block and the clamping groove, the plow blades of different sizes can be replaced, thereby further expanding the application scope of the arable land plow. When replacing, the plow blade can be disassembled by only pressing the clamping block and pulling the connecting block outward. BRIEF DESCRIPTION OF THE DRAWINGS
