[0001] The present application relates to the technical field of water channel equipment, and in particular to a water channel head capable of automatically raising and lowering water channels in farmland. Background Art
[0002] With the continuous development of social economy and the increasing level of science and technology, my country's agriculture is also booming. Agricultural canals, as channels for farmland irrigation, can divert water from external sources into the canals, and then use the canals to irrigate the farmland, so that water resources are reasonably allocated and ensure that farmland can be effectively irrigated when there is water shortage. It plays an important role in agriculture.
[0003] In the prior art, there is an agricultural water channel, which includes a channel body and a valve. The valve is slidably connected to the channel body. The sliding direction of the valve is vertical. A heightening frame is also provided on the channel body. The top of the heightening frame extends upward and is higher than the channel body. A driving handle and a driving assembly are also provided on the heightening frame. The driving handle drives the valve to slide through the driving assembly. When in use, the user turns the driving handle and manually adjusts the height of the valve through the driving assembly, thereby irrigating the farmland.
[0004] Regarding the above-mentioned related technologies, since the existing technology requires the user to observe whether the farmland is short of water, and when the farmland is short of water, the user needs to personally walk to the vicinity of the elevated frame, manually turn the driving handle to adjust the height of the valve, and then observe the water level of the farmland, and personally close the valve when the water level is appropriate, which greatly increases the user's workload. Utility Model Content
[0005] In order to reduce the workload of users when adjusting canal valves, the present application provides a farmland canal head that can automatically raise and lower it.
[0006] The present application provides a farmland canal head that can automatically rise and fall, which adopts the following technical solution:
[0007] A farmland canal head that can be automatically raised and lowered comprises a canal body and a valve. A mounting frame is also provided on the canal body. The valve is slidably connected to the mounting frame. The bottom end of the valve contacts the inner bottom wall of the canal body. A driving mechanism is provided on the mounting frame. The driving mechanism comprises a driving member and a driving assembly. The driving assembly is used to drive the valve to slide, and the driving member is used to drive the driving assembly to operate.
[0008] By adopting the above technical solution, the drive member and the drive assembly are arranged so that when the valve needs to be opened to adjust the water level, the drive member can drive the drive assembly to operate, thereby driving the valve to slide upward, and then the water source on one side of the valve is injected into the other side, thereby realizing the allocation of water resources. Compared with the prior art that requires the user to manually turn the drive handle to drive the valve displacement, the present application reduces the workload of the user when adjusting the canal valve, and at the same time increases the efficiency of adjusting the canal valve.
[0009] Preferably, a filter screen frame is further provided on the channel body, the filter screen frame is located on one side of the valve, and the bottom end of the filter screen frame is embedded in the inner bottom wall of the channel body.
[0010] By adopting the above technical solution, the filter frame is set so that when the valve is opened, the filter frame can intercept the debris entering the water source from the side of the valve away from the filter frame, thereby reducing the probability of the debris in the water source flowing into the farmland along with the water flow, thereby ensuring the irrigation effect and protecting the farmland at the same time.

[0013] Preferably, the displacement assembly comprises a rotating member and a rotating screw, the rotating screw is rotatably connected to the mounting frame, the rotating screw passes through the displacement frame, and is threadedly connected to the displacement frame.
[0014] By adopting the above technical solution and the specific setting of the displacement assembly, the rotating screw can drive the displacement frame to slide under the drive of the rotating member, so that the displacement frame can stop at multiple heights, so that the user can adjust the height of the filter screen according to the specific situation, which is convenient for the user to clean the debris in the filter screen frame.
[0015] Preferably, a guide rod is further provided on the channel body, the guide rod is arranged parallel to the rotating screw rod, the guide rod passes through the displacement frame, and is slidably connected to the displacement frame.
[0016] By adopting the above technical solution, the setting of the guide rod effectively increases the stability of the displacement frame under the drive of the displacement screw, thereby ensuring the stability of the displacement frame when driving the filter frame to slide. At the same time, the existence of the guide rod can also guide the sliding of the displacement frame.

[0018] By adopting the above technical solution and specifically arranging the water level detection component and the control component, the detection component can detect the water level on the side where the filter frame is located, and feed back the water level value to the control component. When the water level on the side where the filter frame is located is too low, the control component can control the operation of the drive component, thereby causing the valve to rise and open, thereby increasing the water level on the side where the filter frame is located, thereby realizing automatic adjustment of the water level.

The existence of the driving screw makes it possible to adjust the height of the valve lifting and lowering, thereby facilitating the user to control the water level.

Compared with the prior art, which requires the user to manually rotate the driving handle to drive the valve displacement, the present application reduces the workload of the user when adjusting the canal valve, and at the same time increases the efficiency of adjusting the canal valve. ;
[0025] 2. The setting of the filter frame enables the filter frame to intercept the debris entering the water source from the side of the valve away from the filter frame when the valve is opened, thereby reducing the probability of the debris in the water source flowing into the farmland along with the water flow, thereby ensuring the irrigation effect and protecting the farmland at the same time;

The bottom end of the valve 2 contacts the inner bottom wall of the canal body 1. A driving mechanism 4 is arranged on the mounting frame 3.

[0034] Reference Figure 1 and Figure 2 The valve 2 is embedded in the mounting frame 3 at both ends along the length of the channel body 1 and is slidably connected to the mounting frame 3. The sliding direction of the valve 2 is the vertical direction, and the bottom end of the valve 2 is in contact with the inner bottom wall of the channel body 1.

The top and bottom ends of the driving screw 421 are both rotatably connected to the mounting frame 3 through bearings. A brake device is also arranged on the driving motor, and the brake device is used to lock the output shaft when the output shaft of the driving motor stops. The brake device is a prior art, so it is not described in detail.
[0036] Reference Figure 1 and Figure 3 The connecting frame 422 is located in the valve 2 and is fixedly connected to the valve 2 by bolts. The top of the connecting frame 422 is exposed from the top of the valve 2. The connecting frame 422 is sleeved on the driving screw 421 and is threadedly connected to the driving screw 421.

When the valve 2 is in an open state, the bottom end of the buffer frame 51 is lower than the bottom end of the valve 2, and the buffer spring 52 is in a normal state. When the valve 2 is lowered from the open state to the closed state, the buffer frame 51 gradually abuts against the inner bottom wall of the channel body 1. After the buffer frame 51 abuts against the inner bottom wall of the channel body 1, the buffer frame 51 slides relative to the channel body 1, and the buffer spring 52 is gradually compressed.

The guide rod 83 is vertically arranged, and the top and bottom ends of the guide rod 83 are both fixedly connected to the mounting frame 3. The guide rod 83 passes through the displacement frame 7 and is slidably connected to the displacement frame 7.
[0043] The implementation principle of the automatic raising and lowering canal head of a farmland in the embodiment of the present application is as follows: when in use, when the water level value detected by the water level detection member 43 is less than the preset value, the control member 44 controls the driving member 41 to drive the driving screw 421 to rotate, so that the driving screw 421 drives the valve 2 to move up, so that the two sides of the valve 2 are connected.
