[0002] At present, based on the analysis of water and fertilizer utilization in traditional tillage and irrigation methods, strip tillage + shallow buried drip irrigation and different nitrogen fertilizer management measures are used to establish a high-yield and high-efficiency spring corn production system suitable for the region, which can further tap the potential for efficient use of nitrogen fertilizer and sustainable use of water resources. Through the interaction of strip tillage and shallow buried drip irrigation, it can have a certain positive impact on the spatial distribution of soil water and nitrogen, nitrogen absorption and distribution, and utilization efficiency, providing a scientific basis for improving corn yield and water and nitrogen utilization efficiency under conservation tillage in the Xiliaohe Plain.

[0003] The applicant and its research team (including the inventor) conducted extensive and in-depth research on the above issues through the project "Regulating Effects of Strip Tillage Shallow Buried Drip Irrigation on Spatial and Temporal Distribution of Soil Water and Nitrogen and Its Utilization Efficiency".

Conventional drip irrigation equipment, such as drip irrigation belts, their arrangement devices, and recovery devices, do not conform to the experimental and planting environment of this region. In particular, the recovery devices of drip irrigation belts mostly pull the drip irrigation belts out of the soil by simple pulling. In this process, the drip irrigation belts are easily broken due to the continuous and constant pulling force, and the recovery device cannot work normally and continuously, which greatly affects the work efficiency.

[0035] [Example 1]

[0036] like Figure 1 , 2As shown, the drip irrigation tape storage device suitable for strip tillage and shallow buried drip irrigation planting mode described in this embodiment is driven by a traction machine or animal power or human power. When a traction machine (such as a tractor) is used to drive the storage device, the storage device is provided with a three-point suspension system that is connected to the traction machine in a transmission manner. Further, for the driving operation of the storage device, if a traction machine such as a tractor is used, the power comes from the traction machine, and the power can be distributed to the functional components of the storage device through a transfer case, a transmission system, etc. This transmission can be achieved by any existing device, which will not be repeated here. When animal power or human power is used to pull the storage device (such as when it is inconvenient to use large machinery in a small-scale experiment), a walking wheel can be set on the storage device, that is, the walking wheel in contact with the ground can be used as a power source, and it distributes the power to the functional components of the storage device through a corresponding transmission system (or device) so that the corresponding function can be achieved by running together.

[0037] Specifically, the storage device includes a frame, a belt collecting wheel, a guide wheel, and an adjusting arm; wherein, the frame is used to construct a base platform of the storage device, and the belt collecting wheel, the guide wheel, and the adjusting arm are respectively mounted on the frame, and when a traction machine is used to drive the storage device, a three-point suspension system for establishing a transmission connection between the storage device and the traction machine is arranged on the frame; the frame is the base platform of the entire storage device, and its specific structure is not specifically limited, and can be implemented by a structure such as a frame, and the specific structure of the frame is determined according to the assembly requirements of various functional components of the storage device, and will not be repeated here.

[0038] Specifically, the tape collecting wheel is used for winding and storing the drip irrigation tape. The tape collecting wheel has a wheel frame, and the wheel frame is used to construct an assembly connection between the wheel collecting frame and the frame. The tape collecting wheel can be a structure with a cylindrical roller and side wheels at both ends. The drip irrigation tape is wound on the roller of the tape collecting wheel, and the side wheels at both ends are used to limit the drip irrigation tape from falling off the roller.

[0039] Specifically, the guide wheel is assembled on the frame through an adjusting arm. The adjusting arm is rod-shaped. One end of the adjusting arm is movably connected to the frame, and the other end is movably connected to the guide wheel. The adjusting arm extends in the opposite direction of the forward direction of the storage device and the traction machinery. The adjusting arm realizes the rotation of the guide wheel itself, and the guide wheel relies on the adjusting arm to swing within a certain range.

[0040] Furthermore, the belt collecting wheel is mounted in the middle of the frame, and the belt collecting wheel is provided with a driving wheel, and the driving wheel is in driving connection with the transmission component of the traction machinery, so that the belt collecting wheel can actively wind up and collect the drip irrigation tape. When in use, the traction machinery drives the collection and storage device to move forward along the ridge, and the end of the drip irrigation tape exposed from the soil is wound backward through the guide wheel, and the end is fixed on the belt collecting wheel; as the collection and storage device moves forward, the belt collecting wheel is driven by the transmission device to rotate, and the drip irrigation tape is tightened and wound; because the adjustment arm and the guide wheel extend backward, and the guide wheel is also driven to rotate, it is more conducive to taking the drip irrigation tape out of the soil.

[0041] [Example 2]

[0042] like Figure 2 As shown, based on the above embodiment, the guide wheel described in this embodiment is an eccentric wheel. The guide wheel includes a small wheel arc and a large wheel arc. The radius of the small wheel arc is smaller than the radius of the large wheel arc. The small wheel arc and the large wheel arc are smoothly connected to form an eccentric wheel. The guide wheel with an eccentric structure has a structure similar to that of a belt collecting wheel. The difference is that the guide wheel only needs to realize the winding of a single drip irrigation tape around the guide wheel. Its core function is to realize instantaneous (the time of greater pulling force is shorter, and the specific duration depends on the travel speed of the storage device, the rotation speed of the belt collecting wheel and the guide wheel) strong pulling of the drip irrigation tape through its eccentric structure. The pulling force is limited within the range that does not damage the drip irrigation tape, so that the drip irrigation tape can be pulled out completely and smoothly.

[0043] The guide wheel is provided with a rotating shaft, and the rotating shaft is located on the line connecting the centers of the small wheel arc and the large wheel arc.

[0044] The guide wheel is provided with a driving part, and the driving part is in driving connection with the transmission component of the traction machinery, so as to realize that the guide wheel actively winds up and pulls the drip irrigation belt.

[0045] like Figure 2 As shown, the middle part of the guide wheel is provided with an axis groove, and the rotating shaft is located between the center line of the small wheel arc and the large wheel arc. The rotating shaft is movably mounted on the axis groove, and inner springs are provided in the axis groove and on both sides of the rotating shaft for keeping the rotating shaft in the direction of the axis groove biased toward the small wheel arc without external force. The rotating shaft of the guide wheel is a movable axis connection mode, and the inner spring buffers the reaction force of the drip irrigation belt when it is pulled, that is, when the drip irrigation belt is covered with thick soil or the covered soil is hard, it is not easy to be pulled out. At this time, the storage device as a whole is still moving normally, and the pulling force on the drip irrigation belt will continue to increase, and the drip irrigation belt may be broken. Therefore, when the guide wheel with a movable axis connection encounters the above situation, the inner spring will partially absorb the pulling force of the storage device on the drip irrigation belt, and to a certain extent delay the pulling force from directly and effectively acting on the drip irrigation belt, causing the drip irrigation belt to be damaged.

[0046] The guide wheel is provided with a rim which is higher than the peripheral surface of the guide wheel. The rim is used to prevent the drip irrigation belt from escaping from the guide wheel.

[0047] [Example 3]

[0048] like Figure 2 As shown, based on the above embodiment, the guide wheel of this embodiment is provided with an anti-skid strip, and the anti-skid strip is provided in multiple and evenly distributed on the circumference of the large wheel arc part of the guide wheel. The provision of the anti-skid strip will help the guide wheel to rotate counterclockwise (in the direction of pulling the drip irrigation tape upward), and in the process of the large wheel arc part of the guide wheel from the bottom (starting to contact the drip irrigation tape), tightening upward, and continuously applying force to pull the drip irrigation tape, to prevent the drip irrigation tape from slipping on the guide wheel, so as to improve the pulling effect of the guide wheel.

[0049] The adjusting arm is provided with a return spring, which is arranged at the movable connection between the adjusting arm and the frame. The return spring is used to keep the adjusting arm in a horizontal state without the action of external force.

[0050] It can be seen from the above embodiments that the basis for achieving the technical effect of the present application is to try to avoid the pulling force acting directly and continuously on the drip irrigation belt, especially when the drip irrigation belt is buried in an unconventional soil and is not easy to be pulled out simply, otherwise the drip irrigation belt will be broken, affecting the recovery efficiency. Therefore, based on the above embodiments, when the guide wheel is already in a tightened state along the shaft groove, if the drip irrigation belt has not been successfully pulled out, the continuous movement of the storage device is very likely to break the drip irrigation belt. Therefore, when in the above situation, the adjustment arm will swing downward, that is, the guide wheel moves further down to the ground, and the horizontal torque becomes shorter. Therefore, on the one hand, the pulling force can be buffered, and on the other hand, the guide wheel pulls the drip irrigation belt close to the ground, so that it can be successfully pulled out without breaking.

[0051] like Figure 3 This is the state diagram of the regulating arm and the guide wheel pulling the drip irrigation belt normally, and the regulating arm does not swing at this time; Figure 4 The guide wheel rotates to the lower position, and continues to rotate to contact the drip irrigation belt and pull it upward. At this time, the adjustment arm still does not swing; Figure 5 In order to prevent the drip irrigation tape from being pulled out easily, the adjusting arm is swung down, the guide wheel is sunk and the drip irrigation tape is pulled close to the ground.

[0052] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
