Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a hydraulic segmented original soil taking machine, which aims to improve the soil taking quality and reduce the disturbance to the soil sample, thereby providing more accurate samples for subsequent soil analysis. Background Art

[0002] Soil sampling is a very important task in agricultural research, geological exploration and environmental monitoring, and its results directly affect subsequent analysis and research. Therefore, the performance of soil sampling equipment is crucial to ensure the representativeness and integrity of soil samples. However, existing soil sampling equipment has many shortcomings in actual use and urgently needs to be improved.

[0003] At present, most of the soil sampling equipment on the market are mechanical, manual or electric devices. The sampling effect of these devices in soft soil is acceptable, but they often show many problems in hard or complex terrain. For example, mechanical soil sampling equipment often causes soil disturbance during the soil sampling process, affecting the integrity of the soil samples. In addition, the sampling efficiency of these devices is low, especially in hard soil layers, and multiple operations are required to obtain qualified soil samples, which not only increases the labor intensity, but also prolongs the sampling time and reduces the overall work efficiency. The adaptability of existing equipment for complex terrain or different soil conditions is also relatively poor. Their power system and soil sampling mechanism design are often not reasonable enough, which makes the equipment easy to be damaged during operation or cannot provide sufficient power, affecting the soil sampling depth and sample quality. In addition, many existing soil sampling equipment are complicated to operate and require operators to have a high level of technical skills, otherwise it is difficult to ensure the consistency and accuracy of soil samples.

[0004] In summary, the existing technology has obvious deficiencies in sampling quality, operating efficiency, equipment adaptability and ease of operation. There is an urgent need for a new type of soil sampling equipment to improve the quality and efficiency of soil sampling and ensure that high-quality undisturbed soil samples can be efficiently obtained under different soil conditions.

[0010] Furthermore, the hydraulic motor generates hydraulic power inside the motor through the pressure of the hydraulic oil, drives the output shaft to rotate, and converts hydraulic energy into mechanical energy; the hydraulic motor can provide sufficient speed and torque according to the working requirements of the earth picker to ensure that the earth picker overcomes the circumferential resistance of the soil during operation and achieves smooth rotational movement; the hydraulic motor cooperates with the earth picker transmission system, and transmits the output power of the hydraulic motor to the earth picker through the gear transmission structure, thereby realizing the effective earth picking function of the earth picker.

[0011] Furthermore, the hydraulic system includes a hydraulic pump for providing hydraulic energy, a filter for filtering hydraulic oil, a relief valve for adjusting pressure, a three-position four-way solenoid valve for controlling the movement of the lifting cylinder, a two-position two-way normally closed solenoid valve for controlling the operating state of the hydraulic motor, and a throttle valve for stabilizing the oil inlet flow of the hydraulic motor; the three-position four-way solenoid valve controls the movement direction of the lifting cylinder by switching the electromagnetic switch to drive the soil picker to move upward or downward to complete the soil picking operation; the two-position two-way normally closed solenoid valve controls the start and stop state of the hydraulic motor, and drives the soil picker to rotate or stop rotating by switching the electromagnetic switch; the hydraulic system realizes precise control and stable operation of the soil picker through the coordinated action of various components, ensuring the smooth progress of the soil picking process.

[0012] Furthermore, the connecting member includes a fixed cylinder and a connecting cylinder, the fixed cylinder is used to install the bearing, and the connecting cylinder is used to cooperate with the transmission gear through a key; the structural design of the fixed cylinder can accommodate the bearing, ensure the tight connection between the bearing and the soil extractor frame, and provide support for the stable operation of the soil extractor sliding block; the connecting cylinder reliably combines the fixed cylinder with the transmission gear through a key connection, so that the power of the hydraulic motor can be efficiently transmitted to the soil extractor, realizing the rotation and movement functions of the soil extractor; the connecting member connects the lifting cylinder, the soil extractor frame and the hydraulic motor through the cooperation of the fixed cylinder and the connecting cylinder to form an integral structure, ensuring the structural stability and movement accuracy of the soil extractor sliding block.

[0013] The beneficial effects of the present invention are:

[0014] (1) The hydraulic segmented soil sampling machine adopts segmented soil sampling design, which enables soil samples at different depths to be separated independently, ensuring the integrity and accuracy of the soil samples, and is suitable for more detailed soil analysis.

[0015] (2) The earth-moving machine adopts a hydraulic drive system, which makes the earth-moving process more efficient and quick, can significantly reduce the operation time, and at the same time reduces the labor intensity.

[0016] (3) The soil extraction pipe boot and built-in ring cutter structure can effectively meet the soil extraction needs in different soil environments. Whether it is soft soil or relatively hard geological environment, it can stably and reliably complete the soil extraction task.

[0017] (4) The overall design of the equipment is compact, small in size and light in weight, which is convenient for on-site operation under different terrain conditions and meets the flexibility requirements of field soil excavation work.

[0018] (5) The segmented design of the built-in ring cutter is a major innovation of the present invention. In the future, it can be combined with intelligent and automated technologies to further improve the performance of the earth-moving machine and provide technical support for diversified soil research.
