Description
Technical Field
[0001] The utility model relates to the technical field of soil plastic film, in particular to an auxiliary device for monitoring and sampling soil plastic film residues. Background Technique
[0002] Soil plastic film, that is, the plastic film covering the soil surface, has been widely used in agricultural production. Initially, it was mainly used to increase soil temperature, maintain soil moisture, promote crop growth and development, and increase yields. With the continuous progress of technology, the types and functions of plastic films have become increasingly rich. For example, plastic films with functions such as weed control and pest control have emerged one after another. Plastic films can effectively reduce the loss of soil heat and increase soil temperature, which is crucial for the growth and development of crops, especially in the early spring and late autumn seasons. At the same time, it can reduce the evaporation of soil moisture, maintain soil moisture, and provide a good growth environment for crops. By improving the soil environment and growth conditions, plastic films can promote the growth of crop roots, improve the absorption capacity of crops, thereby increasing crop yields and improving crop quality. Since plastic films are difficult to completely degrade in the soil, long-term use will cause a large amount of plastic film residues to remain in the soil. These residual plastic films will damage the soil structure, affect soil aeration and water permeability, reduce soil fertility, and hinder the growth of crop roots, posing a serious threat to the sustainable development of agriculture. Residual plastic films will damage the soil aggregate structure, making the soil become loose or compact. Through monitoring and sampling, the status of plastic film residues can be understood in a timely manner, and corresponding measures can be taken to prevent further deterioration of the soil structure. Therefore, there is a particular need for an auxiliary device for monitoring and sampling soil plastic film residues.
[0003] However, for the existing soil plastic film residue monitoring and sampling devices, before monitoring, a 1m×1m square sample plot needs to be dug to measure the plastic film residue amount in the 30cm soil layer. Usually, iron stakes are used as the four-corner fixed support points, and then a rope is used to enclose a 1m×1m square, and then excavation is carried out. This not only affects the excavation, but also easily causes the position to shift during the process of opening the ditch for the sample plot. At the same time, due to the soft ground, the support will sink into the ground, resulting in an uneven height of the sampling device and affecting the sampling effect. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0021] Please refer toFigures 1-5 , the utility model provides a technical solution: a soil mulch residue monitoring and sampling auxiliary device, including a support rod 1. A threaded groove 2 is provided on the outer wall surface of the bottom end of the support rod 1. An adjusting block 3 is threadedly connected to the bottom surface of the support rod 1. A threaded block 4 is fixedly connected to the inner wall surface of the adjusting block 3. A support foot 5 is fixedly connected to the bottom surface of the adjusting block 3. A foot pad 6 is fixedly connected to the bottom surface of the support foot 5. A sliding device 7 is arranged on the surface of the support rod 1. A connecting disc 8 is fixedly connected to the top end of the support rod 1. A stop groove 9 is provided on the bottom surface of the connecting disc 8. A threaded rod 10 is threadedly connected to the inner wall of the connecting disc 8. A stop pawl 11 is fixedly connected to one end of the threaded rod 10. A nut 12 is threadedly connected to the outer wall surface of the threaded rod 10;
[0022] The sliding device 7 includes a card slot 701, a limiting slot 702, a limiting block 703, an electric push rod 704, a sliding strip 705, a connecting plate 706, a projector 707 and a projection lamp 708. A card slot 701 is provided on the surface of the support rod 1. A limiting slot 702 is provided on the inner wall surface of the card slot 701. A limiting block 703 is slidably connected to the inner wall surface of the limiting slot 702. An electric push rod 704 is fixedly connected to the bottom surface of the limiting block 703. A sliding strip 705 is fixedly connected to one end of the limiting block 703. A connecting plate 706 is fixedly connected to the bottom surface of the sliding strip 705. A projector 707 is fixedly connected to the bottom surface of the connecting plate 706. A projection lamp 708 is installed inside the bottom end of the projector 707. Through the setting of the sliding device 7, the electric push rod 704 can perform telescopic actions according to control instructions. When the electric push rod 704 extends, it pushes the limiting block 703 to slide upward in the limiting slot 702. Since the limiting block 703 is fixedly connected to the sliding strip 705, the sliding strip 705 also moves upward accordingly, thereby driving the connecting plate 706 and the projector 707 and the projection lamp 708 connected below it to rise as a whole. On the contrary, when the electric push rod 704 contracts, the limiting block 703 slides downward in the limiting slot 702 under the action of gravity and the pulling force of the electric push rod 704, causing the projector 707 and the projection lamp 708 to descend. After the projection lamp 708 in the projector 707 receives a working signal, it projects a specific pattern or information onto the target area. By adjusting the height of the electric push rod 704 and the horizontal movement of the sliding strip 705 in the card slot 701, the projection position and angle of the projection lamp 708 can be accurately controlled to meet the projection requirements in different scenarios.
[0023] Furthermore, the inner wall size of the threaded groove 2 is consistent with the outer wall size of the threaded block 4. The adjusting block 3 slides up and down on the surface of the support rod 1 through the threaded groove 2 and the threaded block 4. Through the setting of the threaded groove 2, the adjusting block 3 and the threaded block 4, when the ground is soft and the support rod 1 sinks into the ground, adjusting the height of the adjusting block 3 can make the support foot 5 support the ground to maintain the balance of the support rod 1, improving the adaptability and practicability of the device.
[0024] Furthermore, multiple sets of support feet 5 are provided at the bottom of the adjustment block 3 and are arranged in an equidistant manner around the center of the adjustment block 3. Through the arrangement of the support feet 5, multiple sets of support feet 5 can evenly share the weight of the device, making the device not prone to shaking or tipping during use, providing a reliable guarantee for the normal operation of the device.
[0025] Furthermore, the inner wall size of the limit groove 702 matches the outer wall size of the limit block 703. The limit block 703 slides up and down in the limit groove 702 through the electric push rod 704. Through the arrangement of the limit groove, the limit block 703 and the electric push rod 704, it can effectively prevent the limit block 703 from shaking or shifting during the sliding process, enabling the projector 707 and the projection lamp 708 to accurately reach the predetermined position, improving the projection accuracy and effect.
[0026] Furthermore, a square groove is provided on the bottom surface of the projector 707, and the center of the square groove corresponds to the center of the projection lamp 708. Through the arrangement of the square groove, a square pattern can be accurately projected onto the ground, enabling workers to monitor it only by excavating within the pattern.
[0027] Furthermore, multiple sets of stop grooves 9 are provided on the surface of the connection disk 8, and the inner wall size of the stop grooves 9 matches the outer wall size of the stop pawls 11. Through the arrangement of the stop grooves 9, it can effectively prevent the connection disk 8 from shaking and causing the threaded rod 10 to loosen in strong wind weather, greatly improving the connection stability of the auxiliary device.
[0028] Furthermore, multiple sets of threaded rods 10 are provided on the surface of the connection disk 8 and are arranged in an equidistant manner around the center of the connection disk 8. Through the arrangement of the threaded rods 10, the connection between the connection disk 8 and other components is made more firm and reliable, and at the same time, the connection flexibility is increased.
[0029] Working principle: During the working process of this soil mulch residue monitoring and sampling auxiliary device, first place the support rod 1 at a suitable position near the monitoring and sampling area. By matching the threaded block 4 on the inner wall of the adjusting block 3 with the threaded groove 2 on the outer wall of the bottom end of the support rod 1, the height of the support rod 1 can be adjusted according to the actual ground conditions to ensure the overall stability of the device. When the ground is soft and the support rod 1 sinks into the ground, the adjusting block 3 can be rotated to move it upward, driving the support feet 5 and the foot pads 6 to lift, so that the support rod 1 can be disengaged from the sunken ground and readjusted to a stable state. The support feet 5 are arranged at equal intervals around the center of the adjusting block 3. This layout can evenly distribute the weight of the device and further enhance the stability of the device on different terrains. The connecting plate 8 is located at the top of the support rod 1 and is connected to the threaded rod 10 through the internal thread. When it is necessary to fix certain components or connect other devices, the threaded rod 10 can be rotated so that the stop pawl 11 at one end is engaged in the stop groove 9 on the bottom surface of the connecting plate 8, and then tightened with the nut 12 to ensure the firmness of the connection. Such a design facilitates the flexible connection and fixation of various auxiliary devices according to different monitoring and sampling requirements. The sliding device 7 plays an important role during the monitoring and sampling process. The card slot 701 is opened on the surface of the support rod 1, and the limit block 703 in the limit slot 702 slides up and down under the action of the electric push rod 704. When it is necessary to adjust the heights of the projector 707 and the projection lamp 708, the electric push rod 704 extends or contracts, driving the limit block 703, the sliding bar 705, the connecting plate 706, and the projector 707 and the projection lamp 708 to move up and down as a whole. At the same time, the sliding bar 705 can move horizontally in the card slot 701, so as to realize the precise adjustment of the projection position of the projection lamp 708. According to the square groove opened at the bottom of the projector 707, a square pattern can be accurately projected onto the ground, enabling workers to only dig within the pattern for monitoring. The model of the electric push rod 704 is XYDHA24-800. In this way, the use process of a soil mulch residue monitoring and sampling auxiliary device is completed.
