Description

Technical Field

[0001] The invention relates to the field of ditch digging equipment, in particular to a ditch digging device for highland barley field planting and a ditch-ridge combined irrigation and drainage method. Background Art

[0002] Highland barley, scientifically known as naked barley, is a cereal crop of the genus Hordeum in the Poaceae family. It is characterized by the separation of the inner and outer husks and the naked grains, so it is also called naked barley, Yuan wheat, and rice barley.

[0003] When planting highland barley in Shigatse, the current traditional planting method of highland barley field planting in Tibet is affected, and its irrigation method is mainly "peripheral irrigation". After irrigation in the "peripheral irrigation" method, it can be drained normally, but most of the land preparation quality is poor, and highland barley fields with low flatness form waterlogging in low-lying areas after irrigation in the "peripheral irrigation" method. Highland barley in the waterlogged area is damaged by waterlogging and cannot grow normally. When digging ditches, excavators can be used for digging, but when digging, the excavator needs to shovel the soil first and then dump the soil in the bucket to one side. It is impossible to clean the soil at the same time during digging, which increases the digging time. At the same time, the ditch needs to be polished twice after digging, which increases the labor intensity of personnel. Therefore, it is necessary to propose a ditch digging device for highland barley field planting and a ditch-ridge combined irrigation and drainage method. Summary of the invention

[0010] Specifically, an outer wall of one side of the cleaning frame is located on one side of the conveyor belt and is fixedly connected with a discharge pipe.

[0011] Specifically, a collecting groove is provided on the outer wall of the conveyor belt, and the impact block is arranged in a semicircular shape.

[0012] A method for using a ditch digging device for highland barley field planting comprises the following steps: using a ridging machine to raise horizontal ridges every 30-40 meters from high to low according to the slope of the plot, so as to divide the highland barley field into a number of large strips, and then using a ditch digger to dig a canal for irrigation and drainage in the longitudinal direction of the highland barley, the canal being 1.5 meters wide and 0.5 meters deep. When digging the ditch, firstly, the device is moved to a desired position by a driving vehicle, and a hydraulic cylinder is started to push a slide block to move downward, and the slide block drives a motor mounting frame and a rotating disk to move downward, so that a bucket under the rotating disk is against the ground to be excavated; The second step is to start the first drive motor, which drives the first rotating rod, the turntable and the bucket to rotate, and dig a ditch on the ground through the bucket. When the conveyor belt moves to the top of the dug ditch, the hydraulic cylinder pushes the cleaning frame downward to move the conveyor belt to the bottom of the turntable, and start the second drive motor to drive the second drive motor to rotate. The second drive motor drives the second rotating rod and the roller to rotate, and the roller drives the conveyor belt to rotate. When the bucket rotates to one side of the conveyor belt, the soil in the bucket falls into the conveyor belt, and the conveyor belt passes the excavated soil through the conveyor belt. The soil is discharged to one side of the ditch through the discharge pipe. When the turntable rotates, it drives the conical extrusion block to rotate. The conical extrusion block presses the conical push block inward and compresses the first spring. When the conical extrusion block is separated from the conical push block, the first spring pushes the conical push block and the impact block to move outward. The impact block abuts against the bucket to shake off the soil in the bucket. The hydraulic cylinder is started to push the slider, the connecting block and the conical push block downward to make the conical push block abut against the ditch ground. The second spring pushes the conical extrusion block and the extrusion roller to abut against the inner wall of the ditch to scrape and finish the inner wall of the ditch. In the third step, a trencher is used to dig long trenches every 15-20 meters in the longitudinal direction of the barley field to connect the barley field, dividing the field into several long strips with a width of 15-20 meters. In the transverse direction, a trencher is used to dig long trenches every 15-20 meters to connect the fields horizontally. The trench width is 30 cm and the depth is 20 cm. The longitudinal and transverse ditches in the large strips divided by the stalks are connected up and down, left and right, and the highland barley fields are divided into several small strips with a width of 15-20 meters and a length of 15-20 meters. When watering, the stalks at the edge of the field are opened for ditch irrigation from the higher part of the highland barley field according to the large strips formed by the stalks. According to the direction of the terrain, after the large strips with high terrain are irrigated, the water inlet is closed, and the water channel of the next large strip is opened. At the same time, the edges of the horizontal earthen ridges of the two large plots are opened to let the excess water in the previous field flow to the large plots with lower terrain. Irrigation is carried out in sequence from the large fields with higher terrain to the fields with lower terrain. In the late growth period of highland barley (June-August), the rainfall in Shigatse area is more concentrated, and all the water inlet ditches are opened to ensure that the ditches of all large barley fields are connected to the irrigation (drainage) channels.

[0013] Beneficial effects of the present invention: (1) The ditch digging device and ditch ridge combined irrigation and drainage method for highland barley field planting described in the present invention starts the first drive motor to drive the turntable and the bucket to rotate, and the ditch is dug on the ground by the bucket. The hydraulic cylinder drives the slider and the motor mounting frame to move up and down to adjust the ditch depth. The second drive motor is started to drive the second rotating rod to rotate. The second rotating rod drives the conveyor belt to transmit the soil shoveled out by the bucket. When the turntable rotates, it drives the conical extrusion block to rotate. The conical extrusion block pushes the conical push block to move inward. When the conical extrusion block is separated from the conical push block, the first spring pushes the impact The block abuts against the outer wall of the bucket to shake off the soil in the bucket. When shoveling soil, the bucket can be vibrated to shake off the soil in the bucket to prevent the soil from sticking in the bucket and affecting the shoveling effect of the bucket. At the same time, the soil can be discharged from the ditch when shoveling soil to speed up the excavation efficiency. After the ditch is excavated, the hydraulic cylinder pushes the connecting block and the conical block to move into the ditch, the conical block abuts against the bottom wall of the ditch, the second spring pushes the conical extrusion block to abut against the inner wall of the ditch, and the driving vehicle drives the conical block and the conical extrusion block to move. The inner wall of the ditch can be polished at the same time during excavation to reduce the labor intensity of personnel.

[0014] (2) The ditch digging device for highland barley field planting and the ditch-ridge combined irrigation and drainage method described in the present invention, when irrigating, follow the terrain direction. After the irrigation of the farmland canal with high terrain is completed, the water inlet is closed, the canal is opened, and an opening is opened on one side of the farmland canal to allow excess water in the upper large field to flow to the large plot of land with lower terrain. Irrigation is carried out in sequence from the large plot of land with higher terrain to the large plot of land with lower terrain, and water is irrigated in sequence to avoid waterlogging. Waterlogging can be avoided to avoid large-scale waterlogging caused by concentrated rainfall. BRIEF DESCRIPTION OF THE DRAWINGS
