DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] The present invention provides a technical solution, and the specific structure is referred to Figures 1 to 8 .

[0051] The right gathering harrow subassembly is connected to the rotary tiller main machine through bolts; the left gathering harrow subassembly is connected to the rotary tiller main machine through bolts; the ridging side plates are connected to both sides of the rotary tiller main machine through bolts; the main machine mounting seat is connected to the left and right sides of the rotary tiller main machine through bolts, and is connected to the roller subassembly through a pin shaft at the same time as the roller lifting device; the left scraper and the right scraper are fixed to both sides of the rotary tiller main machine through bolts.

[0052] The reduction box assembly is connected to the rotary tiller frame by bolts for transmission and deceleration and torque increase; the driving motor is connected to the reduction box assembly by bolts and uses splines for transmission; the rotary frame side plates are fixed to the left and right sides of the rotary tiller frame by bolts; the left rotary tiller half-axle subassembly and the right rotary tiller half-axle subassembly are connected to the rotary frame side plates by bolts, and are connected to the reduction box assembly by spring pins and splines; the rear lifting frame weld is fixed to the rotary frame side plates by bolts; the rear baffle frame weld is connected to the rotary tiller frame and the rotary frame side plates by ear pins, and is connected to the rear lifting frame weld by pins. The ear pin connection is convenient for installation, and the rear baffle frame weld can be rotated around the ear pin, and the rear baffle frame weld can be adjusted in height by the lifting device of the rear lifting frame weld; the intermediate plow is fixed to the front end of the reduction box assembly by bolts to supplement the land that is partially leaked by the gearbox; the rotary tiller frame is mainly used to carry the functional parts of the entire rotary tiller and to connect with the traction equipment.

[0053] The rotary tiller is connected to the rotary tiller seat by bolts and self-locking nuts. The bolt connection can facilitate the replacement of the rotary tiller, which is a wearing part, and ensure sustainable and efficient operation. According to the knife seat layout diagram, the rotary tiller is installed in a "human" shape, which can disperse the soil to the left and right during rotary tillage, effectively improving the flatness of the land after rotary tillage.

[0054] like Figure 3 and Figure 5 As shown, the blade holder is arranged from the middle to both sides, with multiple groups of blades arranged on the left and right respectively, each group consists of two rotary tilling blades, the two rotary tilling blades form an angle of 120°, and each group of blades is arranged spirally to the left and right at a difference of 60°.

[0055] "H" shaped blade arrangement. Each set of blades consists of two rotary tillers, each blade is an arc-shaped curved blade facing one side. When installing the blades, each set of blades is installed symmetrically, that is, the curved blades have one arc facing left and one arc facing right. When the blades rotate, the blades move in a "H" shape, which can evenly spread the broken soil to the left and right to achieve the effect of leveling the land.

[0056] The lower fixed rod is welded and connected with the rear baffle frame through a pin shaft; the lower fixed rod and the upper pull rod are both in the form of round tubes, the lower fixed rod is a small diameter tube with threads on the top, the upper pull rod is a large diameter tube with extended cylindrical handles on both sides, and the extended handles of the upper pull rod are embedded in two round holes reserved in the lifting mounting seat and can rotate freely; the lifting mounting seat is fixed on the rotary tiller frame; the threaded pull rod passes through the hole at the top of the upper pull rod and is threadedly connected with the thread at the top of the lower fixed rod; the bearing seat is sleeved on the upper end of the threaded pull rod, and the end face bearing is installed between the bearing seat and the lifting mounting seat; the bearing seat and the threaded pull rod are fixed and rotated radially through the pin shaft, that is, the threaded pull rod and the bearing seat rotate together; the top of the threaded pull rod is connected to the rotating handle through the pin shaft. The threaded pull rod is rotated by rotating the handle to cause the threaded pull rod and the thread at the top of the lower fixed rod to move in a threaded manner to lift the rear baffle frame and weld it, and the rear baffle frame weld rotates around the ear pin shaft to achieve the lifting function. Since the rear baffle frame welds in an arc motion, the lifting mounting seat and the upper pull rod can rotate around the extended cylindrical handle of the upper pull rod.

[0057] The fixed mounting seat is fixed to the rotary tiller frame by bolts; the telescopic adjustment rod is adjusted horizontally through the square sleeve and the fixed mounting seat, and the horizontal width distance is adjusted and fixed by bolts; the adjustment tube is adjusted in the vertical direction by using a large tube to cover a small tube, and then fixed by bolts; the disc harrow plow adopts its own rotatable structure, and uses the forward power of the traction equipment to make the disc harrow plow perform unpowered rotational motion, thereby preventing sliding friction with the land during the ridging operation and increasing the resistance.

[0058] The roller is installed with a shaft and a bearing and welded to the bracket; the roller scraper bracket is installed with a pin and welded to the bracket; the scraper is connected to the roller scraper bracket through the pin and then connected with a return spring to keep a certain gap between the scraper and the outer surface of the roller.

[0059] The main machine of the rotary tiller uses a drive motor connected to the gearbox assembly to reduce speed and increase torque. At the same time, the reduction box is arranged in the middle to form a symmetrical and stable structure with the frames on both sides. The reduction box drives the half-axles on the left and right to rotate respectively. The layout design of the rotary tiller seat on the half-axles adopts a scientific and reasonable uniform layout, so that the half-axles are evenly stressed during operation, reducing impact and extending the service life of the machine. At the same time, the rotary tiller is connected by bolts, and the wearing parts can be easily replaced, which increases the service life of the entire machine. When arranging and installing the rotary tiller, the "human" structure is used for installation, which can disperse the soil blocks to the left and right during rotary tillage, and the rotary tillage effect is looser. It is convenient for the subsequent sowing operation.

[0060] Adding left and right gathering harrow structures on the basis of the rotary tillage main machine can gather the broken soil on both sides to the middle, and then achieve the effect of uniform evacuation through the rotating cutting and left and right evacuation of the "human" shaped rotary tiller of the rotary tiller blade shaft. At the same time, the left and right scrapers at the rear end are used to gather the broken soil into a trapezoidal ridge, which is flattened and tidied by the roller at the rear. The land can be arranged into a sowing shape at one time, which greatly improves the planting efficiency.

[0061] The left and right gathering harrows can adjust the width and height according to the planting requirements, and the adjustment process only needs one person to operate, and the operation can be completed manually; greatly improving the convenience of operation. At the same time, the rear roller can be adjusted in height by rotating the handle (the adjustment principle is the same as the welding and lifting of the rear baffle of the rotary tillage main machine). It is used to adjust the ridge height. The entire operation process only needs one person to complete.

[0062] When deep rotary tillage is required, only the rotary tillage main unit can be used for deep rotary tillage; when rotary tillage and ridging are required at the same time, the functions of the whole machine accessories can be used at the same time to achieve rotary tillage and ridging at the same time, which greatly improves the working efficiency. It is different from the existing ridging machines, which need to perform rotary tillage before ridging.

[0063] The specific installation effects are as follows:

[0064] 1) The left and right gathering harrows are fixed to the rotary tiller frame by bolts; the driving motor is connected to the reduction box and fixed to the rotary tiller frame; the two side plates are fixed to the rotary tiller frame; the left and right half shafts are fixed between the reduction box and the left and right side plates; the left and right half shafts are equipped with replaceable rotary tiller blades; the rear baffle is welded and installed on the rotary tiller frame using a pin shaft; the left and right scrapers are installed below the weld of the rear baffle; and a leveling drum structure is installed at the rear end;

[0065] 2) The left and right gathering harrows adopt a non-powered self-rotating structure, which uses the power of the traction equipment to roll forward by itself, and plays the function of gathering the crushed soil in the middle;

[0066] 3) The left and right half-axle rotary tillage blades are installed in a "human" shape and connected by bolts. At the same time, the rotary tillage blades are arranged in a circle around the blade shaft, so that the blade shaft is evenly stressed during rotary tillage operation, which increases the service life. The "human" shaped blade head can disperse the soil to the left and right, and the rotary tillage effect is better. The bolt-connected rotary tillage blade can be replaced when it is damaged when the rotary tillage encounters hard objects such as stones and iron blocks.

[0067] 4) The rear guard frame welding of the rotary tillage main machine and the roller adopt a rotating lifting structure to easily realize the lifting height adjustment function of the components, and the operation is simple and convenient.

[0068] 5) Adding an intermediate plow in the middle of the rotary tillage blade in the middle of the reduction box can make up for the part that cannot be tilled due to the obstruction of the intermediate reduction box, thus avoiding the problem of missing rotation.
