Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling, and particularly relates to a soil sampling device for environmental monitoring. Background Art

[0002] Soil is the source of human food, so soil monitoring is very important. Soil directly affects human health, so agricultural soil pollution has always been a concern for people. The main sources of soil pollution are air pollution, industrial waste residue pollution, and chemical fertilizer and pesticide pollution. Air pollution brings pollutants in the air to the soil through dry and wet deposition of the atmosphere; industrial waste residue pollution is a type of pollutant that is difficult to treat. Industrial enterprises often stack waste residues in the open air without proper treatment, and the pollutants in the waste residues will penetrate into the soil through the leaching action of rainwater; chemical fertilizer and pesticide pollution is caused by the excessive use of chemical fertilizers and pesticides, which changes the chemical properties of the soil, changes the soil pH, destroys the soil structure and the habitat of microorganisms, and causes a decline in soil fertility.

[0003] When the existing soil sampling device is in use, in some cases, the soil surface is severely compacted, making it difficult for the sampling device to penetrate the soil, and it is also difficult to take out the soil in the sampling device after sampling, resulting in low practicability. Summary of the Invention

[0004] The utility model provides a soil sampling device for environmental monitoring, aiming to solve the problem that when the existing soil sampling device is in use, in some cases, the soil surface is severely compacted, making it difficult for the sampling device to penetrate the soil, and it is also difficult to take out the soil in the sampling device after sampling, resulting in low practicability.

[0005] An embodiment of the utility model provides a soil sampling device for environmental monitoring, including a rod body. A cross bar is fixedly connected to the upper end of the rod body. An isolation cylinder is fixedly connected in the rod body. A soil pushing mechanism is arranged in the isolation cylinder. A sampling cylinder is threadedly connected to the bottom end of the rod body. A foot-operating mechanism is also arranged outside the rod body.

[0006] Further, the cross bar and the rod body are in a "T" shape, and rubber sleeves are sleeved on both ends of the cross bar.

[0007] By adopting the above technical solution, the rubber sleeves can prevent the hands of the staff from slipping when pressing downwards.

[0008] Further, the diameter of the isolation cylinder is smaller than that of the rod body, and a cavity is formed between the outer wall surface of the isolation cylinder and the inner wall surface of the rod body.

[0009] By adopting the above technical solution, the rod body can protect the internal isolation cylinder, so that the foot-operating mechanism can only be installed on the rod body and cannot damage the isolation cylinder.

[0010] Further, the bulldozing mechanism includes a push rod slidably disposed inside the isolation cylinder. The upper end of the push rod passes through the cross bar and extends to the outside, and the bottom of the push rod extends into the sampling cylinder.

[0011] By adopting the above technical solution, the push rod slides in the isolation cylinder. After the sampling cylinder collects the soil sample, the push rod is pushed, and thus the sampled soil can be pushed out of the sampling cylinder.

[0012] Further, a limiting plate is fixedly connected to the top of the push rod.

[0013] By adopting the above technical solution, the limiting plate can prevent the push rod from sliding from the isolation cylinder into the sampling cylinder and then sliding out of the sampling cylinder.

[0014] Further, a push plate is fixedly connected to the bottom of the push rod in the sampling cylinder, and the diameter of the push plate is adapted to the sampling cylinder.

[0015] By adopting the above technical solution, when the push rod is pushed, the push plate can push all the sampled soil in the sampling cylinder out.

[0016] Further, the bottom of the sampling cylinder is in a shovel shape, and straight notch openings are provided on the surface of the sampling cylinder.

[0017] By adopting the above technical solution, the shovel-shaped sampling cylinder is convenient to insert into the soil, which can effectively avoid the situation where the soil is too hard to be inserted. At the same time, the soil can enter the sampling cylinder from the straight notch openings, increasing the soil inlet area of the sampling cylinder.

[0018] Further, the foot-operating mechanism includes a threaded hole provided on the surface of the rod body and a sliding sleeve slidably disposed on the surface of the rod body. The sliding sleeve is fixed to the rod body by a bolt, and feet are fixedly connected to both side surfaces of the sliding sleeve.

[0019] By adopting the above technical solution, the sliding sleeve can slide on the surface of the rod body and is fixed by the bolt and the threaded hole. The user can step on the feet to apply a downward force to the whole, greatly reducing the force for the user to insert the sampling cylinder into the soil.

[0020] Further, the length of the bolt is less than the thickness of the cavity.

[0021] By adopting the above technical solution, after the bolt is screwed into the threaded hole, the sliding sleeve can be fixed on the rod body, and the bolt cannot touch the outer wall surface of the isolation cylinder and cannot damage the isolation cylinder.

[0022] The beneficial effects of the present utility model are as follows:

[0023] 1. Through the arrangement of the rod body, the rod body can protect the internal isolation cylinder, so that the foot-operated mechanism can only be installed on the rod body and cannot damage the isolation cylinder.

[0024] 2. Through the arrangement of the soil pushing mechanism, the push rod slides in the isolation cylinder. After the sampling cylinder collects the soil sample, the push rod is pushed, and then the sampled soil can be pushed out of the sampling cylinder.

[0025] 3. Through the arrangement of the foot-operated mechanism, the sliding sleeve can slide on the surface of the rod body and is fixed by bolts and threaded holes. The user can step on the foot pedal to apply a downward force to the whole, greatly reducing the force for the user to insert the sampling cylinder into the soil.

[0026] 4. Through the arrangement of the sampling cylinder, the shovel-shaped sampling cylinder is convenient to insert into the soil, which can effectively avoid the situation that the soil is too hard to be inserted. At the same time, the soil can enter the sampling cylinder from the straight groove opening, increasing the soil inlet area of the sampling cylinder.

[0033] Referring to Figure 1-2 , an embodiment of the present utility model provides a soil sampling device for environmental monitoring, including a rod body 1. A cross bar 2 is fixedly connected to the upper end of the rod body 1. The cross bar 2 and the rod body 1 are in a "T" shape. Rubber sleeves 21 are sleeved on both ends of the cross bar 2. The rubber sleeves 21 can prevent the user's hand from slipping when pressing downwards.

[0034] Referring to Figure 1-2 , an isolation cylinder 3 is fixedly connected in the rod body 1. The diameter of the isolation cylinder 3 is smaller than that of the rod body 1. A cavity 31 is formed between the outer wall surface of the isolation cylinder 3 and the inner wall surface of the rod body 1. The rod body 1 can protect the internal isolation cylinder 3, so that the foot pedal mechanism 6 can only be installed on the rod body 1 and cannot damage the isolation cylinder 3.

[0035] Referring to Figure 1-2 , a soil pushing mechanism 4 is provided in the isolation cylinder 3. The soil pushing mechanism 4 includes a push rod 41 slidably arranged inside the isolation cylinder 3. The upper end of the push rod 41 passes through the cross bar 2 and extends to the outside. The bottom of the push rod 41 extends into the sampling cylinder 5. A limit plate 42 is fixedly connected to the top of the push rod 41. A push plate 43 is fixedly connected to the bottom of the push rod 41 in the sampling cylinder 5. The diameter of the push plate 43 is adapted to that of the sampling cylinder 5. The push rod 41 slides in the isolation cylinder 3. After the sampling cylinder 5 collects the soil sample, the push rod 41 is pushed, and then the push plate 43 at the bottom of the push rod 41 can push the sampled soil out of the sampling cylinder 5. The limit plate 42 can prevent the push rod 41 from sliding from the isolation cylinder 3 into the sampling cylinder 5 and then sliding out of the sampling cylinder 5.

[0036] Referring to Figure 1-2 , the bottom end of the rod body 1 is threadedly connected with a sampling cylinder 5. The bottom of the sampling cylinder 5 is in a shovel shape. Straight groove openings 51 are provided on the surface of the sampling cylinder 5. The shovel-shaped sampling cylinder 5 is convenient for inserting into the soil, which can effectively avoid the situation that the soil is too hard to be inserted. At the same time, the soil can enter the sampling cylinder 5 from the straight groove openings 51, increasing the soil inlet area of the sampling cylinder 5.

[0037] Referring to Figure 1-2, an external pedal mechanism 6 is further provided on the rod body 1. The pedal mechanism 6 includes a threaded hole 61 provided on the surface of the rod body 1 and a sliding sleeve 62 sliding on the surface of the rod body 1. The sliding sleeve 62 is fixed to the rod body 1 by a bolt. Pedals 63 are fixedly connected to both side surfaces of the sliding sleeve 62. The sliding sleeve 62 can slide on the surface of the rod body 1 and is fixed to the threaded hole 61 by a bolt. The user can step on the pedals 63 to apply a downward force to the whole, greatly reducing the force for the user to insert the sampling cylinder 5 into the soil. The length of the bolt is less than the thickness of the cavity 31. After the bolt is screwed into the threaded hole 61, the sliding sleeve 62 can be fixed on the rod body 1, and the bolt cannot touch the outer wall surface of the isolation cylinder 3 and cannot damage the isolation cylinder 3.

[0038] The specific implementation method is as follows: When in use, the user takes the sampling device to the sampling location. First, the user fixes the sliding sleeve 62 at a suitable position by a bolt, then grabs the cross bar 2, steps on the pedals 63, and steps the sampling cylinder 5 into the soil. At this time, the soil can push the push rod 41 upward through the push plate 43. Then, the sampling cylinder 5 is pulled out of the soil, and by pushing the push rod 41, all the soil in the sampling cylinder 5 falls into the collection device. If it is necessary to change the height of the pedals 63, loosen the bolt, reselect the threaded hole 61 and screw it in.
