Technical Field

[0001] The present invention relates to the technical field of soil sampling, and particularly to a portable soil sampling device for ecological environment planning. Background Art

[0002] Ecological environment planning is a reasonable arrangement of time and space for human activities and the environment to make the ecological environment develop in harmony with the economic society. It is to conserve and improve the structure and function of the ecosystem in a planned way. It aims to promote the virtuous cycle of regional and urban ecosystems, maintain the continuous symbiosis, coordinated development of the relationship between humans and nature, humans and the environment, and pursue social civilization, economic efficiency and ecological environment harmony. In ecological environment planning, the obtained soil samples can be used to evaluate key indicators such as soil fertility, moisture status, and pH value, so as to understand the ecological status of the soil and provide a decision-making basis for planners. When sampling, a soil sampling device will be used for sampling. The sampling device can help planners quickly and accurately obtain soil samples, and then analyze the soil quality and ecological status.

[0003] The existing soil sampling devices are divided into manual or electric types. When the manual type is operating, it is difficult to collect deep soil, the operation is relatively laborious, and when some spiral manual soil sampling devices are sampling, they will damage the soil layer structure, and it is easy to produce errors when analyzing. Although the electric type is relatively labor-saving in use, due to its heavy weight, it is relatively laborious to carry, and there is a problem that it is not convenient to carry. Therefore, there is a need for a soil sampling device that is convenient to carry manually, has a labor-saving operation, and is convenient for taking a complete sample from the deep soil layer.

Side ratchet discs 507 are fixedly installed inside both sides of the driving gear 503. The ratchet teeth directions of the two side ratchet discs 507 are opposite. And limiting rods 508 are inserted into both sides of the force application frame 504. A waist-shaped plate 509 is fixedly installed at one end of the limiting rod 508. A spring 5010 is sleeved at one end of the limiting rod 508. Both ends of the spring 5010 are fixedly connected to the force application frame 504 and the waist-shaped plate 509 respectively. Through the two limiting rods 508, the effect of limiting the two side ratchet discs 507 is achieved. Furthermore, when the telescopic push rod 502 swings, different states of the driving gear 503 are switched. When the two limiting rods 508 are respectively in contact with the two side ratchet discs 507, since the limiting rods 508 are clamped on the ratchet teeth, the force application frame 504 and the driving gear 503 are fixedly connected. When the two limiting rods 508 are not in contact with the side ratchet discs 507, the force application frame 504 cannot drive the driving gear 503. When the driving gear 503 is not driven, the air pump 402 is slid to the position of the force application rod 506 at the lower end of the force application frame 504, which is convenient to swing the force application frame 504 through the telescopic push rod 502, so that the force application rod 506 repeatedly pumps air into the air pump 402. Since the ratchet teeth directions of the two side ratchet discs 507 are opposite, when one limiting rod 508 is in contact with one side ratchet disc 507, the other limiting rod 508 is not in contact with the other side ratchet disc 507. By switching the contact state bidirectionally, the motion state of the driving gear 503 for forward or reverse rotation is restricted, which is convenient to apply a downward or upward force to the rack 201. Adjusting screw rods 5011 are threadedly connected to both sides of the waist-shaped plate 509. When the adjusting screw rods 5011 are turned,It is convenient to switch the state of whether the limiting rod 508 is in contact with the side ratchet disc 507. When the adjusting screw 5011 presses against one side of the force-applying frame 504, the spring 5010 is in a stretched state, so that the limiting rod 508 is not in contact with the side ratchet disc 507.,
