Description

Technical Field

[0001] The utility model relates to the technical field of ditch digging for forage grass planting; more specifically, it relates to a ditch digging device for forage grass planting. Background Art

[0002] When planting forage grass, it is necessary to dig ditches. At present, in the process of forage grass planting, since forage grass seeds are generally small, if sown too deep, they cannot germinate, and if sown too shallow, the surface soil is extremely easy to be dried by the wind, resulting in uneven emergence. Therefore, a ditch opener is needed to dig ditches during forage grass planting. Currently, the ditch opener is mainly composed of a cross bar and multiple groups of ditch digging teeth. The ditch digging teeth are mostly fixedly installed, and the positions of each group of ditch digging teeth are fixed and immovable. Each ditch digging tooth cannot adjust the distance according to the width and depth of the ditch. Therefore, there is an urgent need for a ditch digging device for forage grass planting to solve the above problems. Summary of the Utility Model

The mounting sleeve groove is vertically sleeved with a mounting frame, and at the bottom position of the mounting frame, a mounting secondary shaft is horizontally sleeved, and a harrow tooth is sleeved on the surface of the mounting secondary shaft.

[0005] Further, cutting blades are arranged on the surface of the traveling wheel, and the cutting blades are arranged in a staggered and equidistant manner on the outer surface of the traveling wheel. Through the design of multiple groups of cutting blades on the surface of the traveling wheel, it is convenient to cut the weeds on the ground during its movement, and the situation that the ditch digging is affected due to excessive weeds can be effectively reduced.

[0006] Further, gaskets are pressed on the inner wall of the mounting sleeve groove and the surface of the mounting secondary shaft. The gaskets are small parts for the friction between two objects. In order to avoid wear during the installation of the mounting sleeve groove and the mounting frame, and the mounting secondary shaft and the harrow tooth, gaskets are selected for partitioning. It can not only reduce the loss of parts, but also increase the fastening degree between the two according to needs. It is used as a good isolation tool and reinforcement tool, thereby strengthening the stability during the installation of the mounting sleeve groove and the mounting frame, and the mounting secondary shaft and the harrow tooth.

[0007] Further, reserved holes are provided on the surface of the installation sleeve groove and at the top of the mounting frame, and locking bolts are threadedly connected to the inner walls of the reserved holes. After the mounting frame is vertically adjusted to an appropriate height in the installation sleeve groove, the reserved holes on the surface of the mounting frame coincide with the reserved holes on the surface of the installation sleeve groove. Then, the locking bolts are aligned and inserted and rotated and tightened, so as to conveniently adjust the height of the mounting frame and realize flexible adjustment of the ditching depth.

[0008] Further, a ditching plow blade is installed at the bottom of the harrow teeth, and reserved holes are provided on the surfaces of the ditching plow blade and the bottom of the harrow teeth. Through the design of disassembling and assembling the ditching plow blade at the bottom of the harrow teeth by inserting screws into the reserved holes and rotating and tightening, it is convenient to replace the ditching plow blade.

[0009] Further, a collar is provided at the top of the harrow teeth, and reserved holes are provided on the surface of the collar and locking bolts are threadedly connected inside. By sleeving the collar at the top of the harrow teeth onto the installation secondary shaft, it is convenient to adjust the appropriate distance between each group of harrow teeth, and at the same time, it is also convenient to adjust the angle of the harrow teeth sleeved on the installation secondary shaft, so that the ditching angle and distance can be flexibly adjusted.

[0010] The technical effects and advantages of the present utility model:

[0011] 1. Through the horizontal movement and forward and backward rotation operations of multiple groups of harrow teeth on the installation secondary shaft, and in cooperation with the vertical adjustment of the whole installation secondary shaft driven by the mounting frame, the present utility model can adjust the appropriate distance and angle between each group of harrow teeth according to the width of the ditching, and at the same time, can also adjust the overall height of the mounting frame according to the depth of the ditching, so as to meet the requirements of the sowing density and depth of forage grass, and make its use operation very fast and convenient.

[0012] 2.
