Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation equipment, in particular to a field walking type automatic reel sprinkler. Background Art

[0002] In modern agricultural production, efficient and precise irrigation methods are crucial to crop growth and yield. As a commonly used irrigation device, self-propelled reel sprinklers play an important role in farmland irrigation. However, existing self-propelled reel sprinklers have exposed some significant problems during actual operation.

[0003] Existing mobile automatic reel sprinklers typically consist of a chassis, a frame, a reel, and a sprinkler carriage. The sprinkler carriage relies on rollers to maneuver through the field. However, farmland topography is often complex and varied, fraught with uncertainty. In real-world field environments, gullies and raised obstacles are common. When the sprinkler carriage encounters these obstacles during operation, the rollers, due to limitations in their structure and operation, can easily become stuck in the gullies or become blocked by raised obstacles. Once this occurs, the rollers lose their ability to move, becoming stuck and unable to move forward. This not only hinders the sprinkler carriage's movement, affecting the continuity and efficiency of irrigation operations, but can also cause damage to the equipment, increasing repair costs and time. Furthermore, the inability of the sprinkler carriage to move smoothly can lead to uneven irrigation, with some areas receiving insufficient irrigation, thus affecting crop growth and development, ultimately negatively impacting the yield and quality of agricultural production. Utility Model Content

[0004] In response to the above-mentioned technical deficiencies, the purpose of the present utility model is to provide a field walking automatic reel sprinkler that better disperses the pressure of the roller, so that the walking unit can more easily cross ditches and obstacles, avoiding operation interruptions caused by roller jamming.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The control wheel that stirs cage connects with the control wheel shaft and the control wheel shaft, and the control wheel shaft is connected with the control wheel shaft through the support wheel hub, and the control wheel shaft is connected with the control wheel shaft through the support wheel hub.

[0007] Preferably, a positioning sleeve is fixedly provided on the upper end of the connecting frame; the positioning sleeve is detachably sleeved on the connecting frame; an adjusting bolt is installed on the positioning sleeve, and the connecting frame is provided with a plurality of adjusting screw holes adapted to the adjusting bolt.

[0008] Preferably, there are two springs, which are symmetrically arranged on both sides of the connecting frame; a positioning pin is fixedly provided at the lower end of the spring; and a plurality of positioning holes adapted to the positioning pin are provided on the support plate, and the positioning pin is inserted into any one of the positioning holes.

[0009] Preferably, a limiting plate is fixedly provided on the side of the connecting seat; an arc-shaped limiting hole is provided on the limiting plate; a limiting column is fixedly provided on the support plate, and the limiting column can be slidably inserted in the arc-shaped limiting hole; the axis of the arc-shaped limiting hole coincides with the axis of the driving wheel.

[0010] Preferably, there are two driven wheels; the two driven wheels are symmetrically arranged on both sides of the driving wheel.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] First, obstacle-crossing capabilities have been significantly improved. The crawler-type structure of the travel unit allows the crawler track to fully contact the ditch or obstacle when the central driving wheel gets stuck, significantly increasing the force-bearing surface. Compared to traditional rollers, this design better distributes pressure, allowing the travel unit to more easily cross ditches and obstacles, avoiding interruptions caused by stuck rollers.

[0013] Secondly, the stability and reliability of the sprinkler vehicle's travel are improved. Because the support plate is hingedly mounted on the connecting frame and the axis height of the driven wheel is higher than the axis height of the driving wheel, when encountering an obstacle, the support plate can drive the driven wheel to deflect within a certain angle, making it easier for the driven wheel to contact the ground, providing more stable support and power transmission for the travel unit, effectively ensuring the stable travel of the sprinkler vehicle in complex terrain.

[0014] Furthermore, the efficiency and quality of irrigation operations are enhanced. Because the travel unit can smoothly navigate various terrain obstacles in the field, the sprinkler truck maintains continuous and stable movement, ensuring uniform and complete irrigation. This avoids the problem of insufficient or excessive irrigation in certain areas due to sprinkler truck obstruction, provides a more suitable growing environment for crops, and helps improve crop yield and quality.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 3As shown, a field walking type automatic reel sprinkler comprises a chassis 4, a stand 3, a reel 2 and a sprinkler trolley 1. The stand 3 is fixed on the chassis 4, the reel 2 is rotatably mounted on the stand 3, the sprinkler trolley 1 is connected to one end of the reel 2, a support frame 6 is provided on the sprinkler trolley 1, and a walking unit 5 is provided on the support frame 6; two walking units 5 are configured and symmetrically arranged on both sides of the support frame 6; the walking unit 5 comprises: a connecting frame 51, a connecting seat, a supporting plate, a driving wheel 54, a driven wheel 53, a chain belt 52 and a spring 57; the upper end of the connecting frame 51 is connected to the supporting frame 6, and the lower end is fixedly connected to the connecting seat The connecting seat is pivotally mounted on one side of the support plate; the upper end of the spring 57 is fixedly connected to the connecting frame 51, and the lower end is connected to the support plate; the driving wheel 54 and the driven wheel 53 are pivotally mounted on the side of the support plate away from the connecting seat; the chain belt 52 is sleeved and mounted on the driving wheel 54 and the driven wheel 53, and the driving wheel 54 and the driven wheel 53 are connected through the chain belt 52 to realize power transmission; the axis of the driving wheel 54 passes through the hinge point of the connecting seat and the support plate; the driven wheel 53 is located on one side of the driving wheel 54; the axis height of the driven wheel 53 is higher than the axis height of the driving wheel 54, forming a crawler structure.

[0022] Furthermore, during normal travel, the chain belt 52 beneath the driving wheel 54 contacts the ground, reducing the contact area between the chain belt 52 and the ground and preventing large amounts of mud from adhering to the chain belt 52. The tracked structure increases the contact area between the sprinkler vehicle 1 and the ground, improving grip and stability. When the driving wheel 54 gets stuck in a ditch or encounters an obstacle, the track can contact the edge of the ditch or the surface of the obstacle, reducing the risk of getting stuck by increasing the force-bearing area and helping the driving wheel 54 to successfully overcome the obstacle. The support plate is hingedly connected to the connecting frame 51 via a connecting seat, allowing the support plate to deflect within a certain angle. This design enables the walking unit 5 to automatically adjust its posture according to changes in terrain, maintaining optimal contact with the ground, thereby improving its obstacle-crossing capability. The provision of springs 57 provides a cushioning effect for the walking unit 5 on undulating terrain, reducing driving instability caused by vibration. Furthermore, by adjusting the position of the locating pins 58 in the different locating holes 56 on the support plate, the height and angle of the driven wheel 53 can be fine-tuned to adapt to different terrain conditions.

[0023] In this embodiment, a positioning sleeve 55 is fixedly mounted on the upper end of the connecting frame 51. The positioning sleeve 55 is removably attached to the connecting frame 51. An adjustment bolt is mounted on the positioning sleeve 55, and the connecting frame 51 is provided with multiple adjustment screw holes that are compatible with the adjustment bolts. By inserting the adjustment bolts into different adjustment screw holes, the overall height of the traveling unit 5 can be adjusted to meet the needs of different working environments.

[0024] In this embodiment, two springs 57 are provided, symmetrically arranged on either side of the connecting frame 51. A positioning pin 58 is fixedly mounted at the lower end of the spring 57. The support plate is provided with a plurality of positioning holes 56 that match the positioning pins 58, and the positioning pin 58 is inserted into any of the positioning holes 56. By adjusting the position of the positioning pin 58 in different positions of the positioning holes 56, the tension of the spring 57 is adjusted, thereby adjusting the deflection angle range of the support plate.

[0025] In this embodiment, a limit plate 511 is fixedly mounted on the side of the connecting base; the limit plate 511 is provided with an arc-shaped limit hole 510; a limit post 59 is fixedly mounted on the support plate and slidably engages in the arc-shaped limit hole 510; the axis of the arc-shaped limit hole 510 coincides with the axis of the driving wheel 54. The sliding arrangement of the limit post 59 in the arc-shaped limit hole 510 limits the maximum deflection angle of the support plate.

[0026] In this embodiment, two driven wheels 53 are configured; the two driven wheels 53 are symmetrically arranged on both sides of the driving wheel 54.

[0027] Directions:

[0028] 1. Equipment Deployment

[0029] Location selection: First, transport the automatic reel sprinkler to the working location and select the edge of the field with flat ground and suitable irrigation conditions for deployment. Make sure there are no obvious obstacles around the equipment so that the sprinkler can move smoothly.

[0030] Installation and fixing: Place the device on a flat surface and adjust the angle of the device according to the shape of the land and irrigation requirements. Use fixing devices (such as anchors, pins, etc.) to firmly fix the device to the ground to prevent it from moving or tipping over during operation.

[0031] Connect the water source: Connect the sprinkler's water source interface to the water supply pipe to ensure sufficient water supply and stable pressure. At the same time, check whether all connection parts are well sealed to prevent water leakage.

[0032] 2. Sprinkler irrigation operation

[0033] Start the equipment: Connect the power supply of the sprinkler or start the engine to put the equipment into operation. Adjust the sprinkler parameters according to actual needs, such as water volume and sprinkler range.

[0034] Towing the sprinkler: The sprinkler is pulled to the other end of the field using the reel's power drive system. During the towing process, the reel will simultaneously release the hose to ensure that the sprinkler can travel along the preset path.

[0035] Sprinkler irrigation: When the sprinkler truck arrives at the designated location, it begins. Pressurized water is delivered via pipes to the truck's spray guns, where it is atomized and sprayed onto the crops. During the sprinkler irrigation process, the intensity and duration of the sprinkler can be adjusted according to the crop type and growth stage.

[0036] 3. Automatic recycling

[0037] Recycling Start: After the sprinkler operation is completed, the recycling process is started. At this time, the reel power drive system will rotate in the opposite direction, driving the water pipe to wind around the reel and pulling the sprinkler carriage back to the starting position.

[0038] Speed ​​and Adjustment: The recovery speed can be adjusted based on actual needs. Some sprinklers are equipped with a speed controller, which allows users to adjust the recovery speed via the control panel or remote control. The sprinkler carriage's trajectory can also be manually adjusted to suit terrain changes and obstacles.

[0039] Complete Recycling: The recycling process ends when the sprinkler carriage returns to its starting position and stops moving. At this point, turn off the sprinkler power or engine and disconnect the water source. Also, check that all components are intact for the next use.

[0040] IV. Precautions

[0041] Safe operation: During the operation, safe operating procedures should be strictly followed to ensure the safety of personnel and equipment.

[0042] Maintenance: Perform regular maintenance on the sprinkler, check the wear of each component and replace damaged parts in a timely manner. At the same time, keep the equipment clean and dry to prevent rust and corrosion.

[0043] Environmental adaptation: Select appropriate sprinkler irrigation modes and parameters according to different terrain and climatic conditions to achieve the best irrigation effect.
