Description

Technical Field

[0001] The present invention specifically relates to a high - efficiency garden soil remediation device based on garden soil quality, belonging to the technical field of garden soil remediation. Background Art

[0002] In the prior art, the soil remediation method usually adopts spraying a remediation liquid into the soil to achieve soil remediation; during implementation, the corresponding spraying effect of the remediation liquid on the soil is achieved through an automated spraying device. Although this method can complete the remediation of the soil to a certain extent, this method not only requires prior tilling of the soil to be remediated, but also cannot ensure that the remediation liquid is evenly sprayed on the ground. For this reason, Chinese Patent Authorization Publication No.: CN118385266B discloses a high - efficiency garden soil remediation device based on garden soil quality. This structure can shake the preliminarily mixed remediation liquid in the up - and - down direction to ensure the mixing effect of the remediation liquid; however, this structure has high requirements for the particle size of the sprayed powder, and cannot spray powders with relatively high particle sizes, and cannot spray and cover deep into the soil. In addition, during the spraying process, the sprayed liquid is prone to volatilization. Another example is Chinese Patent Authorization Publication No.: CN118950683B, which discloses a high - efficiency garden soil remediation device. This high - efficiency garden soil remediation device can achieve high - efficiency in - situ remediation of the compacted soil in the garden, without the need to transport the soil, and can separate large stones and other sundries during remediation. However, large stones are prone to jamming or damage between the spiral blades. Summary of the Invention

[0003] To solve the above problems, the present invention proposes a high - efficiency garden soil remediation device based on garden soil quality, which can break up soil clods and directly throw stones, achieve in - situ soil remediation, and can form an interlayer composite remediation system on the soil surface, with good remediation effects.

After the soil is collected, a trough is formed on the garden ground, and the repair powder is put into the inner side of the trough by the powder spraying unit. Then, the import conveyor belt sends the collected soil to the stone throwing unit. The stone throwing unit loosens and breaks the soil clods into small pieces, and directly screens out the stones and sundries larger than the blade intervals of the first electric vertical rotary paddle, the electric horizontal rotary paddle and the second electric vertical rotary paddle, and throws them outside the repair device; the soil clods broken into small pieces and the stones smaller than the blade gap enter the crushing and throwing unit; the crushing and throwing unit operates, and through the cooperation of the second electric vertical rotary paddle and the electric horizontal rotary paddle, three-dimensional dispersion of the soil clods on the bumps is realized. During the dispersion process, the impact of the stones on the soil clods can increase the crushing effect of the soil clods; then, as the import conveyor belt moves forward, the crushed soil automatically enters the second throwing conveyor belt through the blanking gap, and the stones stuck in the blanking gap are thrown onto the first throwing conveyor belt by the first electric vertical rotary paddle; then, the thickness fixing and spraying unit works, and the second throwing conveyor belt and the collecting channel form a moving closed channel, and the top surface of the soil is fixed in thickness through the thickness fixing neck; so that the soil layer thickness passing through the thickness fixing neck is always the same, thus ensuring that the soil volume reaching the spraying unit is always stable.

When the stone throwing unit works, the inlet channel 12 sends the soil into the stone throwing opening, and through the continuous rotation of the electric stone throwing paddle 15, the stones and soil blocks smaller than the blade interval are directly sent inside the partition seat 13. For the large soil blocks, they are broken by the electric stone throwing paddle 15 and then sent into the partition seat 13.
