[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-4 As shown, an adjustable dryland soil loosening machine includes a soil loosening machine body 1, a connecting frame 3 installed at the top of the soil loosening machine body 1, a fixed seat 4 fixedly connected to one end of the soil loosening machine body 1, a support frame 5 provided at the end of the fixed seat 4 away from the soil loosening machine body 1, a plurality of soil loosening components 6 are installed horizontally at equal intervals on the support frame 5, and two fixed baffles 7 are symmetrically fixedly connected to the end of the fixed seat 4 away from the soil loosening machine body 1, the two fixed baffles 7 are located above and below the support frame 5 respectively, and a lifting mechanism for adjusting the height of the support frame 5 is provided on the fixed seat 4.

[0031] The lifting mechanism includes: a connecting component mounted on the fixed base 4;

[0032] The connecting assembly includes: a second connecting plate 2012 disposed at the end of the fixed base 4 away from the main body 1 of the tumbler, the second connecting plate 2012 being located between two fixed baffles 7, and a first connecting plate 207 being fixedly connected to the end of the second connecting plate 2012 away from the fixed base 4, the first connecting plate 207 having a T-shaped vertical cross section, both outer walls of the first connecting plate 207 being truncated square, and a sliding sleeve 205 being slidably fitted onto the outer wall of the first connecting plate 207, the sliding sleeve 205 being fixedly connected to the support frame 5, and the sliding sleeve 205 being truncated square and can be easily slidably fitted onto the outer wall of the first connecting plate 207 through the truncated square outer wall;

[0033] A movable component is provided on the fixed base 4;

[0034] In this embodiment, when in use, pushing the connecting frame 3 can move the main body 1 of the soil loosening machine to the dry land. At the same time, through the lifting mechanism, the second connecting plate 2012 can drive the sliding sleeve 205 to move up and down synchronously through the first connecting plate 207. At this time, the support frame 5, driven by the sliding sleeve 205, drives multiple soil loosening components 6 to move synchronously, so that the height of the soil loosening components 6 can be conveniently adjusted, thereby adjusting the corresponding soil loosening depth according to the needs of different crops.

[0035] When multiple soil loosening components 6 wear out and need to be replaced, the lifting mechanism can release the limit on the moving push rod 2011, and then push the support frame 5 to drive the sliding sleeve 205 to slide along the outer wall of the first connecting plate 207. At this time, multiple soil loosening components 6 are moved synchronously under the drive of the support frame 5. Then, the above operation is reversed to easily replace multiple soil loosening components 6, thereby further improving the efficiency of loosening dryland soil.

[0036] In one embodiment, such as Figures 1-3As shown, the moving component includes: a lifting sleeve plate 208 disposed inside the fixed base 4, one end of the lifting sleeve plate 208 is symmetrically and fixedly connected to two connecting shafts 204, both connecting shafts 204 pass through the fixed base 4 and are fixedly connected to the sliding sleeve frame 205, and both connecting shafts 204 are slidably connected to the fixed base 4;

[0037] A drive assembly is provided on the mounting base 4;

[0038] The drive assembly includes: a motor 201 mounted on the top of the fixed base 4, a lead screw 202 fixedly connected to the output end of the motor 201, the lead screw 202 being rotatably connected to the fixed base 4, a lifting sleeve 208 sleeved on the outer wall of the lead screw 202, and the lifting sleeve 208 being threadedly connected to the lead screw 202.

[0039] A guide assembly is provided on the fixed base 4;

[0040] The guide assembly includes: two fixed columns 203 symmetrically fixedly connected inside the fixed base 4, a lead screw 202 located between the two fixed columns 203, and a lifting sleeve 208 slidably sleeved on the outer wall of the two fixed columns 203. Through the cooperation of the moving assembly, the driving assembly and the guide assembly, the lifting sleeve 208 can be stably raised and lowered inside the fixed base 4.

[0041] A limit component is provided on the fixed column 203;

[0042] In one embodiment, such as Figures 2-4 As shown, the limiting component includes: a movable push rod 2011 disposed inside the fixed post 203. The movable push rod 2011 passes through the fixed post 203, the connecting shaft 204, the second connecting plate 2012, and the first connecting plate 207. The movable push rod 2011 is slidably connected to the fixed post 203, the connecting shaft 204, the second connecting plate 2012, and the first connecting plate 207. The outer wall of the end of the movable push rod 2011 that connects to the fixed post 203 is hemispherical. One end of the fixed post 203 has a movable groove 209 for the movable push rod 2011 to slide. The fixed post 203 and the movable push rod 2011 are connected in a sliding manner. A limiting groove 2010 is provided at the contact position of the push rod 2011 to allow the movable push rod 2011 to slide. The limiting groove 2010 is located at the bottom end of the movable groove 209. The inner cavity of the movable groove 209 and the inner cavity of the limiting groove 2010 are interconnected. The movable push rod 2011 can be moved and limited by the limiting groove 2010, which effectively prevents the sliding sleeve 205 from loosening and detaching during the lifting and lowering process. When the movable push rod 2011 contacts the inner wall of the movable groove 209, the limitation on the movable push rod 2011 can be released, so as to facilitate the convenient replacement of the sliding sleeve 205.

[0043] The movable push rod 2011 is equipped with a positioning component;

[0044] In one embodiment, such as Figures 2-4 As shown, the positioning component includes: a limiting baffle 2013 fixedly connected to the end of the movable push rod 2011 away from the fixed post 203, the limiting baffle 2013 being located inside the first connecting plate 207, a positioning plug 206 fixedly connected to the end of the limiting baffle 2013 away from the movable push rod 2011, the outer wall of the end of the positioning plug 206 away from the limiting baffle 2013 being hemispherical, the positioning plug 206 penetrating through the first connecting plate 207 to the outside of one end of the sliding sleeve 205, and both the positioning plug 206 and the limiting baffle 2013 being slidably connected to the first connecting plate 207;

[0045] A reset component is provided on the movable push rod 2011;

[0046] The reset component is a spring 2014 sleeved on the outer wall of the movable push rod 2011. One end of the spring 2014 contacts the outer wall of the limiting baffle 2013, and the other end of the spring 2014 contacts the outer wall of the first connecting plate 207. Through the cooperation of the positioning component and the reset component, the sliding sleeve 205 can be engaged and limited during the replacement of multiple loosening components 6, thereby enabling convenient positioning of the sliding sleeve 205.

[0047] The above embodiment discloses an adjustable dryland soil loosening machine. In use, pushing the connecting frame 3 moves the main body 1 of the soil loosening machine to the dryland. At the same time, the motor 201 is started to drive the lead screw 202 to rotate. At this time, the lifting sleeve 208 moves up and down along the outer wall of the fixed column 203 through the thread driven by the lead screw 202. At the same time, the second connecting plate 2012 moves up and down synchronously through the connecting shaft 204 driven by the lifting sleeve 208 and the first connecting plate 207 driven by the sliding sleeve 205. At this time, the moving push rod 2011 slides along the inner wall of the limiting slide groove 2010 driven by the lifting sleeve 208. At the same time, the support frame 5 drives multiple soil loosening components 6 to move synchronously under the drive of the sliding sleeve 205. This allows for convenient adjustment of the height of the soil loosening components 6, thereby adjusting the corresponding soil loosening depth according to the needs of different crops.

[0048] When multiple soil loosening components 6 wear out and need to be replaced, the start motor 201 drives the lead screw 202 to rotate until the lifting sleeve 208 moves and contacts the top of the inner wall of the fixed seat 4. At this time, the moving push rod 2011, driven by the lifting sleeve 208, separates from the inner wall of the limiting slide groove 2010 and contacts the inner wall of the moving slide groove 209, thereby releasing the limitation on the moving push rod 2011.

[0049] Then, the support frame 5 is pushed to drive the sliding sleeve 205 to slide along the outer wall of the first connecting plate 207. At this time, multiple soil loosening components 6 are moved synchronously under the drive of the support frame 5. Meanwhile, the positioning block 206 is squeezed by the sliding sleeve 205 and pushes the moving push rod 2011 to slide along the inner wall of the moving slide groove 209 through the limiting baffle 2013. At this time, the limiting baffle 2013 is contracted by the moving compression spring 2014. Then, the above operation is reversed, and multiple soil loosening components 6 can be easily replaced, thereby further improving the efficiency of loosening dryland soil.

[0050] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
