DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 11The present invention provides a technical solution: an agricultural equipment for improving soil, comprising a shell 1 and a spoiler component 3, a liquid injection component 2 is provided between the front and rear inner walls of the shell 1, one side of the liquid injection component 2 is connected to the spoiler component 3, a side of the liquid injection component 2 away from the spoiler component 3 is movably connected to a soil crushing component 4, a soil turning component 5 is provided on one side of the shell 1, casters 6 are fixedly connected to the bottom corners of the shell 1, and an improvement liquid tank 7 is fixedly connected to the top of the shell 1.

[0033] In this embodiment, Figure 1 , Figure 3 , Figure 5 and Figures 7 to 9As shown, the injection component 2 includes a fixed shaft 201 fixedly connected between the front and rear inner walls of the shell 1, the fixed shaft 201 runs through the middle of the driving frame 202, the driving frame 202 is composed of three parts: a follower rod 202a, an arc segment 202b and a driving segment 202c, the top surface of the driving segment 202c away from the fixed shaft 201 is fixedly connected with a piston rod 203, the top of the piston rod 203 is integrally formed with a piston sheet 204, the middle of the arc segment 202b and the follower rod 202a are both hollowed out, and the middle walls of the arc segment 202b are integrally formed with a limiting slider 205, the limiting slider 205 is slidably connected to the inside of the limiting slide groove 206, the limiting slide groove 206 is arranged in the middle of both sides of the injection sheet 207, and the piston sheet 2 04 is slidably arranged inside the piston cylinder 209, the end of the piston cylinder 209 away from the piston rod 203 is connected with one end of the hose 2010, the end of the hose 2010 away from the piston cylinder 209 is connected with the top of the injection piece 207, the piston cylinder 209 is fixedly connected inside the welding strip 2011, the piston cylinder 209 and the improved liquid tank 7 are connected through the liquid inlet pipe 2012, the bottom surface of the driving section 202c is attached with a cam 2013, the cam 2013 is sleeved on the middle outer surface of the main shaft 2014, the two ends of the main shaft 2014 are movably connected with end sleeves 2015 by bolts, and the driving shaft 208 is integrally formed between the inner wall of the end of the follower rod 202a away from the arc section 202b; when liquid injection is required, the main The shaft 2014 rotates under the action of the sprocket drive, and the main shaft 2014 drives the cam 2013 to rotate. Since the cam 2013 is eccentrically arranged on the main shaft 2014, the cam 2013 periodically pushes the driving section 202c of the driving frame 202 upward during rotation, so that the driving frame 202 reciprocates around the fixed shaft 201. When the driving section 202c rises, the follower rod 202a falls. The rising driving section 202c pushes the piston plate 204 to move in the piston cylinder 209 through the piston rod 203, and pushes the improved liquid in the piston cylinder 209 into the hose 2010 through the one-way valve 217, and enters the inside of the injection plate 207 through the hose 2010, and finally from the injection plate 207. The liquid is discharged from the liquid outlet hole on the upper part, and in conjunction with the descent of the follower rod 202a, the follower rod 202a will drive the injection piece 207 to be inserted into the soil turned over by the soil-turning component 5, so as to inject the improved liquid into the soil. In addition, during the injection process, the follower rod 202a drives the injection piece 207 to move down and contact the soil, which takes time. During this period of time, the piston piece 204 is also injecting the improved liquid in the piston cylinder 209 into the injection piece 207. Therefore, during the period of time when the injection piece 207 has not yet contacted the soil, the improved liquid will flow out from the liquid outlet hole of the injection piece 207 and drip on the soil surface. This structure simultaneously completes the work of injecting the improved liquid into and outside the soil, so that the penetration and covering effects of the improved liquid are better, thereby improving the quality of soil improvement.

[0034] In this embodiment, Figure 4and Figure 6 As shown, a one-way valve 1 2016 is fixedly connected to the inside of the liquid inlet pipe 2012, a one-way valve 2017 is provided at the connection between the piston cylinder 209 and the hose 2010, both ends of the main shaft 2014 are rotatably connected to the front and rear inner walls of the shell 1, the cam 2013 is eccentrically sleeved on the main shaft 2014, and the cams 2013 are arranged in a spiral staggered manner, and the middle outer surface of the main shaft 2014 is wavy; the one-way valve 1 2016 only allows the liquid inside the improved liquid tank 7 to flow into the piston cylinder 209, while the one-way valve 2017 only allows the liquid inside the piston cylinder 209 to flow into the hose 2010, and the spirally staggered cams 2013 can drive the injection piece 207 to inject liquid into the soil in a wave-like manner in sequence when rotating with the main shaft 2014.

[0035] In this embodiment, Figure 8 and Fig. 9 As shown, the cross-section of the injection piece 207 is diamond-shaped, and liquid outlet holes are equidistantly provided in the middle of the four inclined surfaces of the injection piece 207. A semicircular blade is integrally formed at the bottom end of the injection piece 207, and a silicone extrusion nozzle is installed in the liquid outlet hole (not shown in the figure); the silicone extrusion nozzle will only open when it is subjected to the pressure of the internal improved liquid, which effectively prevents the liquid outlet hole from being blocked by the soil after the injection piece 207 is inserted into the soil. Driven by the driving frame 202, the injection piece 207 has an arc-shaped motion trajectory, and the diamond-shaped structure enables the injection piece 207 to divert the soil into two flows, making it easier to enter and exit the soil.

[0036] In this embodiment, Figure 1 and Figure 7 As shown, the spoiler assembly 3 includes a T-shaped slide groove 301 opened on the right inner wall of the shell 1, and the T-shaped slide groove 301 is slidably connected to a T-shaped lifting rod 302 inside. A linkage telescopic rod 303 is hinged on one side of the bottom end of the T-shaped lifting rod 302. The end of the linkage telescopic rod 303 away from the T-shaped lifting rod 302 is hinged to the end of the driving section 202c. The top of the T-shaped lifting rod 302 penetrates into the interior of the improved liquid tank 7 and is connected to the bottom surface of the spoiler 304; the driving section 202c rotates around the fixed axis 201. During the process, a change in height will occur, and the distance between the driving section 202c and the T-shaped lifting rod 302 will also change. During the movement of the driving section 202c, the T-shaped lifting rod 302 can be driven to move up and down along the inside of the T-shaped slide groove 301 through the linkage telescopic rod 303. At this time, the T-shaped lifting rod 302 drives the spoiler 304 on the top to move up and down synchronously, disturbing the liquid inside the improved liquid tank 7 to prevent precipitation from being generated inside the improved liquid tank 7. This structure can always maintain the effect of the improved liquid.

[0037] In this embodiment, Figure 1 and Figure 10 to Figure 11As shown, the soil crushing assembly 4 includes a circular frame 401 sleeved on the outside of the driving shaft 208, the middle part of the bottom surface of the circular frame 401 is rotatably connected to the inner rod 402, the bottom end of the inner rod 402 is fixedly connected to a spring telescopic rod 403, the bottom surface of the spring telescopic rod 403 is fixedly connected to an inner rotating disk 404, and the bottom surface of the inner rotating disk 404 is equiangularly distributed with three groups of inner crushing blades 405, the middle outer surface of the inner rod 402 is provided with a spiral groove 406, and the position of the inner rod 402 above the spiral groove 406 is interference-fitted with a connecting bearing 407, the outer ring of the connecting bearing 407 is fixedly connected to the top of the inner ring of the outer cylinder 408, and the middle of the outer cylinder 408 A spiral groove 409 is provided, and two spring telescopic rods 4010 are fixedly connected to the bottom end of the outer cylinder 408, an outer rotating ring 4011 is fixedly connected between the bottom ends of the spring telescopic rods 4010, and three groups of outer crushing blades 4012 are equiangularly distributed on the bottom surface of the outer rotating ring 4011, the spiral groove 1 406 and the spiral groove 2 409 have opposite rotation directions, and the starting points of the spiral groove 1 406 and the spiral groove 2 409 coincide with each other, and the pitches are equal, and the spiral groove 1 406 and the spiral groove 2 409 are slidably connected with a guide shaft 4013, and the guide shaft 4013 is integrally formed on one side of the mounting rod 4014, and the mounting rod 4014 is fixedly connected to the front and rear inner parts of the housing 1. The end of the guide shaft 4013 away from the mounting rod 4014 is spherical and embedded in the spiral groove 406. This structure can prevent the guide shaft 4013 from escaping from the spiral groove 406. When the follower rod 202a moves, the height changes, thereby driving the circular frame 401 to rise and fall through the driving shaft 208. When the circular frame 401 rises and falls, it drives the inner rod 402 at the bottom to rise and fall, and the inner rod 402 drives the outer cylinder 408 to rise and fall through the connecting bearing 407. The connecting bearing 407 allows the outer cylinder 408 and the inner rod 402 to rotate relative to each other. During the process of the inner rod 402 and the outer cylinder 408 rising and falling, the inner rod 402 and the outer cylinder 408 can be lifted and lowered. The guide shaft 4013 will drive the inner rod 402 and the outer cylinder 408 to rotate through the spiral groove 1 406 and the spiral groove 2 409. Since the rotation directions of the two spiral grooves are opposite, the rotation directions of the inner rod 402 and the outer cylinder 408 are opposite. The inner rod 402 drives the inner rotating disk 404 and the inner crushing blade 405 below to rotate forward through the spring telescopic rod 1 403, while the outer cylinder 408 drives the outer rotating ring 4011 and the outer crushing blade 4012 below to rotate counterclockwise through the spring telescopic rod 2 4010, so that the two sets of crushing blades can crush the block soil when they descend to contact it, thereby breaking the soil into finer particles, which is convenient for liquid injection improvement.

[0038] In this embodiment, Figure 1As shown, the soil-turning component 5 includes a motor 501 fixedly connected to the front side of the outer shell 1, and the output end of the motor 501 passes through the inner side of the outer shell 1 and is connected to the soil-turning roller 502, and the outer surface of the output end of the motor 501 is fixedly connected with a main sprocket 503, and the main sprocket 503 is connected to the secondary sprocket 504 through a chain, and the secondary sprocket 504 is fixedly connected to the outer surface of one end of the main shaft 2014; after the motor 501 is started, it drives the soil-turning roller 502 and the main sprocket 503 to rotate about their own axes at the same time, and the main sprocket 503 drives the secondary sprocket 504 to rotate through the chain, and the secondary sprocket 504 can drive the injection component 2 to operate.

[0039] The use method and advantages of the present invention: When the agricultural equipment for improving soil is used, the working process is as follows:

[0040] First, start the motor 501 to drive the soil-turning roller 502 to rotate and perform preliminary soil turning. At the same time, after the soil-turning component 5 is started, it can also drive the injection component 2 to operate. The injection component 2 continuously injects the improvement liquid into the soil to improve the soil. At the same time, when the injection component 2 is in operation, it will also drive the soil crushing component 4 and the spoiler component 3 to operate.
