Description

Technical Field

[0001] The utility model relates to the technical field of ditch openers, and more specifically, to a rotary ditch opening device for an orchard ditch opener. Background Art

[0002] When fertilizing in orchard planting, it is necessary to first dig ditches inside the orchard and then bury the fertilizer into the ditches. Currently, representative traditional ditch opening devices in China include chain ditch opening devices, spiral ditch opening devices and other structural models. The above device structures are relatively large in size (volume), have a large turning radius during field operations and cannot operate flexibly. The chain drive has low efficiency and poor stability, especially a very low safety factor, and there are great safety hazards during operation. Moreover, the power loss is large, the soil throwing is uneven in high-humidity and muddy fields, and even the ditch cannot be dug, which brings inconvenience to use.

[0003] The utility model patent with the patent publication number CN217428664U discloses a rotary ditch opening device for an orchard ditch opener, including a positioning flange. In this rotary ditch opening device for an orchard ditch opener, the power shaft is directly meshed with the gears in the gearbox. The gearbox drives the power shaft to rotate through the gears. The power shaft drives the transmission shaft sleeve to rotate. The transmission shaft sleeve drives the rotating disc to rotate. The connecting flange drives the first ditch opening blade and the second ditch opening blade to rotate. The transmission is stable and the transmission efficiency is high, improving the ditch opening efficiency. The included angle between the rotating disc and the power shaft is 85°, so that the excavation surface when the rotating disc drives the first ditch opening blade and the second ditch opening blade to rotate is not directly perpendicular to the ground. When the first ditch opening blade and the second ditch opening blade cut the soil to dig the ditch, the cutting force is increased. During the ditch opening process, the first ditch opening blade pushes the soil to splash to the upper left side, increasing the soil discharge force, so that the soil will automatically splash upward and move out of the ditch, improving the ditch opening effect.

[0004] However, in actual use of this structure, since the power shaft and the rotating disc are connected and fixed by through bolts, a large force is required to make the ditch opening blade rotate to dig the ditch during the ditch opening process. The entire reverse force is supported by the through bolts, resulting in the through bolts being easily twisted and deformed under the action of torsional force for a long time, reducing the installation and fixation of the rotating disc, and thus there will be certain safety hazards. Therefore, a rotary ditch opening device for an orchard ditch opener is now proposed. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a rotary ditch opening device for an orchard ditch opener to solve the problems raised in the above background art.

[0006] To achieve the above object, the present utility model provides the following technical solution: A rotary ditching device for an orchard ditching machine, comprising a transmission shaft, one end of the transmission shaft is sleeved with a positioning component, a turntable is arranged on one side of the positioning component, a plurality of ditching blades are bolted to the turntable, one side of the turntable abuts against the positioning component, and a locking member is installed at the end of the transmission shaft, and the locking member abuts against the turntable.

[0007] By inserting the transmission shaft into the interior of the gearbox, the transmission shaft is connected to the driving end inside the gearbox, driving the transmission shaft to rotate, so that the transmission shaft drives the turntable to rotate, and the ditching blades rotate accordingly to ditch the ground. During the ditching process, since the positioning component positions the turntable, and one side of the positioning component abuts against the transmission shaft for meshing, while the outside of the turntable is abutted by the locking member, cooperating with the meshing of the turntable and the end of the transmission shaft, the rotation of the turntable is always synchronized with the rotation of the transmission shaft. All the reaction forces generated by the ditching blades and the soil on the turntable are supported by the transmission shaft, thus avoiding the bolts from being loosened or broken due to the force on the bolts when using bolt fixation, thereby improving the stability and safety of ditching.

[0008] Preferably, the transmission shaft includes a shaft rod, a toothed rod, a smooth rod, and a threaded hole. One end of the shaft rod is coaxially provided with a toothed rod, one end of the toothed rod is coaxially provided with a smooth rod, and a threaded hole is coaxially opened at the end of the smooth rod.

[0009] Preferably, teeth are provided at the connection between the toothed rod and the shaft rod, and the teeth are arranged in a ring.

[0010] Preferably, the positioning component includes a positioning disk, bolt rods, and nuts. A plurality of bolt rods are arranged on one side of the positioning disk, the bolt rods are arranged in a ring, and nuts are installed on each bolt rod. A tooth hole for cooperating with the toothed rod is opened in the middle of the positioning disk, and a tooth groove for cooperating with the teeth is opened on one side of the positioning disk.

[0011] Preferably, a plurality of bolt holes are opened on the turntable, and each bolt hole respectively cooperates with a corresponding bolt rod.

[0012] Preferably, the locking member includes a screw rod, a locking nut, and an annular groove. A locking nut is arranged at one end of the screw rod, and an annular groove is opened at the connection where the locking nut is connected and fixed to the screw rod.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. By sleeving the positioning component on the rack, the positioning component meshes with the rack, and the positioning component is pushed against the annularly arranged teeth for further meshing. Thus, when the locking member is screwed into the screw hole, it can abut against the turntable, clamping and fixing the turntable, enabling the turntable to rotate synchronously with the transmission shaft, converting the overall torsional force into meshing force, reducing damage to the transmission shaft, increasing the service life of the transmission shaft, and improving the stability and safety during trenching at the same time.

[0015] 2. By screwing the screw into the screw hole, rotating the locking nut can adjust the depth of the screw screwed into the screw hole. The smooth rod is in sliding fit with the annular groove, enabling the locking nut to abut against the turntable, thereby improving the firmness of the turntable installation.
