Description

Technical Field

[0001] This utility model relates to the field of plowshare technology, specifically a low-resistance, high-efficiency deep-plowing plowshare. Background Technology

[0002] A plow is an agricultural implement used for tilling and loosening soil. It consists of a blade, a traction device, and adjustment components. Utility model patent application CN213991581U discloses a deep-plowing plowshare assembly, comprising: a plow tip, located at the front end of the plowshare assembly, having at least one pointed end for initial soil penetration; a plow blade, located at the rear end of the plow tip, having a cutting edge for secondary soil penetration; a plow arm, located at the rear end of the plow blade, connected to an end away from the cutting edge of the plow blade, having a concave curved surface for tilling soil; and a plow support assembly, located on the back side of the concave curved surface of the plow arm, for supporting and fixing the plow tip, plow blade, and plow arm; the plow tip is provided with an adjustment mechanism for adjusting the forward and backward movement of the plow tip, and the plow tip and the plow support assembly are connected through the adjustment mechanism. The above-mentioned technical solution allows the plow tip to be moved forward by an adjustment mechanism when its initial soil-penetrating function is weakened due to wear. This restores the initial soil-penetrating function and enables the plow tip to be used repeatedly, greatly extending the service life of the plowshare assembly. However, the plow tip is not easy to adjust the angle of insertion. Different soil-penetrating angles result in different tillage resistance. Changing the angle between the plowshare and the traction direction reduces soil friction resistance and increases tillage efficiency. Furthermore, prolonged use of the plow tip can cause damage from impacts with hard objects in the soil, making it difficult to disassemble and replace. This reduces impact damage, increases friction resistance, and affects tillage. Utility Model Content

[0003] The purpose of this invention is to provide a low-resistance, high-efficiency deep-plowing plowshare to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A low-resistance, high-efficiency deep-plowing plowshare includes a plow blade, a plow tip at the front end of the plow blade for breaking the soil, a plow arm at the rear end of the plow blade for guiding and turning the soil, a reinforcing plate at the bottom of the plow blade, a connecting rod at the middle of the reinforcing plate for connecting to an external rotary tiller, and a hydraulic rod connected to the connecting rod at the upper surface of the reinforcing plate near the rear end.

[0005] Furthermore, the plow blade is in the shape of an arc plate, with arc edges on both sides of the left end of the plow blade, and the right end of the plow blade is welded and fixed to the left end of the plow arm.

[0006] In this invention, the plow blade is made of high-strength hard alloy casting, which has both wear resistance and toughness, and is suitable for soil containing stones or heavy clay. The plow blade guides the scooped soil into the plow arm, realizing soil turning, increasing the contact area between soil and air, and the rounded edge reduces frictional resistance with the soil and guides the soil to be scooped up.

[0007] Specifically, the plow arm is crescent-shaped, and the bottom of the lower surface of the plow arm is closely fitted to the top left side of the reinforcing plate.

[0008] In this invention, the end of the plow arm is curved backward, which helps the soil guided by the plow blade to turn over from the top of the plow arm to the rear, thus achieving plowing and loosening of the soil. The reinforcing plate increases the stability of the combination between the plow blade and the plow arm, and increases the resistance to compression in the middle of the plow arm.

[0009] It should be noted that the plow tip is conical in shape, and the upper surface of the plow tip is provided with a groove for guiding the soil. A plate is provided in the middle of the right end face of the plow tip, and screw holes are symmetrically provided on the lower surface of the plate. Each screw hole is provided with a fixing bolt. A limiting plate is also symmetrically provided near the edge of the right end of the plow tip.

[0010] In this invention, the pointed, conical plow tip facilitates initial contact with the soil and allows for rapid insertion and breaking through the soil under the traction of a rotary tiller. A fixing bolt on the insertion plate secures the plow tip to the plow blade. Removing the fixing bolt facilitates the separation of the plow tip from the plow blade for replacement or removal for grinding and repair.

[0011] Specifically, a slot is provided at the bottom left end of the plow blade corresponding to the insertion plate, a through hole communicating with the slot is provided at the bottom of the plow blade, and a limiting groove is provided on the left end face of the plow blade corresponding to the limiting plate.

[0012] In this invention, the insert plate and the slot are plugged in and matched, and the fixing bolt passes through the through hole and is threadedly connected to the screw hole. An external wrench is applied to the fixing bolt to achieve the corresponding tightening installation or disassembly and removal. The limiting plate and the limiting groove are plugged in and matched to further increase the stability of the plow tip and plow blade combination.

[0013] Secondly, a first hinge seat is provided in the middle of the reinforcing plate, a pivot is provided at the bottom of the connecting rod corresponding to the first hinge seat, and a third hinge seat is provided in the middle of the right end face of the connecting rod.

[0014] In this invention, the top of the connecting rod is fixedly connected to the corresponding support rod of the external rotary tiller by bolts. The connecting rod rotates and engages with the first hinge seat in the middle of the reinforcing plate through a rotating shaft, thereby adjusting the tilt angle between the reinforcing plate with plow blades and the ground, which helps to facilitate soil turning.

[0015] In addition, a second hinge seat is provided on the upper surface of the reinforcing plate near the right end. The bottom of the hydraulic rod is rotatably connected to the second hinge seat through a rotating shaft, and the top of the hydraulic rod telescopic arm is rotatably connected to the third hinge seat through a rotating shaft.

[0016] In this invention, one end of the hydraulic rod is rotatably connected to the reinforcing plate, and the other end is rotatably connected to the connecting rod. By adjusting the extension or retraction of the hydraulic rod's telescopic arm on the rotary tiller, the tilt angle between the plow blade and the ground can be adjusted. When the extension arm of the hydraulic rod is extended, the left end of the plow blade and plow tip tilts upward, protecting the left end and reducing damage from impacts to the ground when not plowing. When the extension arm of the hydraulic rod is retracted, the left end of the plow blade and plow tip tilts downward, inserting and cooperating with the slope of the ground soil to perform corresponding soil shoveling and turning.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features a plow tip and plow blade connected by an insert plate and slot, and secured by a fixing bolt. This allows for easy disassembly and installation of the plow tip, facilitating the replacement of damaged plow tips and reducing frictional resistance between the damaged tip and the soil. Guided by the plow arm, soil scooped from the plow blade is discharged from the end of the plow arm, thus turning the soil. The reinforcing plate increases the stability of the plow arm and plow blade assembly, and the hydraulic rod allows for adjustment of the plow tip's tilt angle relative to the ground. This facilitates different tilt angles for turning soil on different soil types, reducing frictional resistance.

[0018] 2. This utility model achieves stability in the combination between the plow tip and the plow blade by setting a limiting plate and a limiting groove for interlocking. The connecting rod with the third hinge seat is movably connected to the reinforcing plate with the plow blade through a hydraulic rod. By adjusting the extension or retraction arm of the hydraulic rod, the angle at which the plow tip and the plow blade are inserted into the ground can be adjusted. A small angle of insertion results in low frictional resistance and shallow soil turning, while a large angle of insertion results in deep soil turning. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1-5 This embodiment provides a technical solution: A low-resistance, high-efficiency deep-plowing plowshare includes a plow blade 1, which is in the shape of an arc plate. The left end of the plow blade 1 has arc edges on both sides, and the right end of the plow blade 1 is welded and fixed to the left end of the plow arm 10.

[0023] In this utility model, the plow blade 1 is made of high-strength hard alloy casting, which has both wear resistance and toughness, and is suitable for soil containing stones or heavy clay. The plow blade 1 guides the soil shoveled into the plow arm 10 to realize soil turning, increase the contact area between soil and air, and the rounded edge reduces the frictional resistance with the soil and guides the soil to be shoveled.

[0024] Furthermore, the front end of the plow blade 1 is provided with a plow tip 2 for breaking the soil. The plow tip 2 is made of high-strength hard alloy casting to increase wear resistance and toughness. The plow tip 2 is cone-shaped. The upper surface of the plow tip 2 is provided with a groove for guiding the soil. The middle of the right end face of the plow tip 2 is provided with an insert plate 21. The lower surface of the insert plate 21 is symmetrically provided with screw holes 210. Each screw hole 210 is provided with a fixing bolt 22. The right end of the plow tip 2 is also symmetrically provided with a limiting plate 20 near the edge.

[0025] In this invention, the pointed, conical plow tip 2 facilitates initial contact with the soil and allows for rapid soil penetration under the traction of a rotary tiller. The insert plate 21 is fitted with a fixing bolt 22 to achieve the combination and fixation between the plow tip 2 and the plow blade 1. The removal of the fixing bolt 22 facilitates the disassembly and separation of the plow tip 2 and the plow blade 1 for replacement or removal for grinding and repair.

[0026] Specifically, a slot 11 is provided at the bottom left end of the plow blade 1, corresponding to the insertion plate 21. A through hole 110 communicating with the slot 11 is provided at the bottom of the plow blade 1. A limiting groove 12 is also provided on the left end face of the plow blade 1, corresponding to the limiting plate 20.

[0027] In this utility model, the insert plate 21 is inserted into the slot 11, and the fixing bolt 22 passes through the through hole 110 and is threaded into the screw hole 210. An external wrench is applied to the fixing bolt 22 to achieve the corresponding tightening installation or disassembly removal. The limiting plate 20 is inserted into the limiting groove 12 to further increase the stability of the plow tip 2 and the plow blade 1 combination.

[0028] It is worth adding that the rear end of the plow blade 1 is provided with a plow arm 10 for guiding and turning the soil. The plow arm 10 is crescent-shaped, and the bottom of the lower surface of the plow arm 10 is in close contact with the top left side of the reinforcing plate 3.

[0029] In this utility model, the plow arm 10 is made of high-strength hard alloy casting, which increases wear resistance and toughness. The end of the plow arm 10 is bent into a rearward arc, which helps the soil guided by the plow blade 1 to turn over from the top of the plow arm 10 to the rearward side, realizing plowing and loosening of the soil. The reinforcing plate 3 increases the stability of the combination between the plow blade 1 and the plow arm 10, and increases the compression resistance of the middle position of the plow arm 10.

[0030] Furthermore, the bottom of the plow blade 1 is provided with a reinforcing plate 3, and the middle of the reinforcing plate 3 is provided with a connecting rod 5 that connects to the external rotary tiller. The upper surface of the reinforcing plate 3 near the rear end is provided with a hydraulic rod 4 that connects to the connecting rod 5.

[0031] It should be noted that a first hinge seat 30 is provided in the middle of the reinforcing plate 3, a rotating shaft 50 is provided at the bottom of the connecting rod 5 corresponding to the first hinge seat 30, and a third hinge seat 51 is provided in the middle of the right end face of the connecting rod 5.

[0032] In this utility model, the top of the connecting rod 5 is fixedly connected to the corresponding support rod of the external rotary tiller by bolts. The connecting rod 5 rotates and engages with the first hinge seat 30 in the middle of the reinforcing plate 3 via the rotating shaft 50, thereby adjusting the tilt angle between the reinforcing plate 3 with the plow blade 1 and the ground, which helps to facilitate soil turning.

[0033] Specifically, a second hinge seat 31 is provided on the upper surface of the reinforcing plate 3 near the right end. The bottom of the hydraulic rod 4 is rotatably connected to the second hinge seat 31 through a rotating shaft, and the top of the telescopic arm of the hydraulic rod 4 is rotatably connected to the third hinge seat 51 through a rotating shaft.

[0034] In this invention, one end of the hydraulic rod 4 is rotatably connected to the reinforcing plate 3, and the other end is rotatably connected to the connecting rod 5. By adjusting the extension or retraction of the hydraulic rod 4 on the rotary tiller, the tilt angle between the plow blade 1 and the ground can be adjusted. When the extension arm of the hydraulic rod 4 is extended, the left end of the plow blade 1 and the plow tip 2 tilts upward, protecting the left end and reducing damage from impacts to the ground when not plowing. When the extension arm of the hydraulic rod 4 is retracted, the left end of the plow blade 1 and the plow tip 2 tilts downward, inserting and cooperating with the slope of the ground soil to perform corresponding soil shoveling and turning.

[0035] In this embodiment, the low-resistance, high-efficiency deep-plowing plowshare is first used by connecting the top of the connecting rod 5 with the third hinge seat 51 to the support rod on the external rotary tiller by screws. Then, the rotating shaft 50 at the bottom of the connecting rod 5 is rotatably connected to the first hinge seat 30 on the reinforcing plate 3. The end of the telescopic arm at the top of the hydraulic rod 4 is rotatably connected to the third hinge seat 51 through the rotating shaft. The bottom of the hydraulic rod 4 is rotatably connected to the second hinge seat 31 through the rotating shaft. The plow blade 1 and the plow arm 10 are connected to the left end of the reinforcing plate 3. The pointed plow tip 2 is inserted into the slot 11 through the insert plate 21. The fixing bolt 22 extends through the through hole 110 into the slot 11 and is threadedly connected to the screw hole 210 on the insert plate 21. The corresponding limiting plate 20 is inserted into the limiting groove 12 to increase the stability of the plow tip 2 and the plow blade 1 combination. When deep tilling is required, the telescopic arm of the hydraulic rod 4 on the external rotary tiller is shortened, which increases the tilt angle between the plow tip 2 and the ground. The upper surfaces of the plow tip 2, plow blade 1, and plow arm 10 are flush and smooth, which helps to guide the shoveled soil to turn over and come into contact with air. The smooth surface reduces the frictional force between the plow tip 2 and the soil. The bottom of the plow tip 2 is shaped like a conical section, which reduces the frictional resistance with the soil when it is initially inserted into the soil. When tilling is not required, the telescopic arm of the hydraulic rod 4 is extended, which makes the left end of the plow tip 2 tilt upward and away from the ground, reducing the risk of collision damage. When the plow tip 2 is worn due to friction after prolonged use, the fixing bolt 22 can be disassembled by using an external wrench to engage with it. The insert plate 21 and the limiting plate 20 on the plow tip 2 can then be separated from the plow blade 1, making it easy to disassemble the plow tip 2 for inspection and replacement. The overall structure is simple and easy to operate. Example

[0036] Please see Figure 6-7 Based on Example 1, this embodiment provides the following technical solution: The plow blade 1 is in the shape of an arc plate. The plow tip 2 is tightly inserted into the tip of the plow blade 1 and is fixed by screws. The plow tip 2 is L-shaped and the tip of the plow tip 2 points downward. A scraper 6 is also provided on the right side of the connection between the plow blade 1 and the plow tip 2. The bottom of the scraper 6 is welded and fixed to the reinforcing plate 3. The middle position of the scraper 6 is close to the plow blade 1. The bottom of the scraper 6 is sharp. The reinforcing plate 3 is fitted with a corresponding connecting rod 5 and a hydraulic rod 4.

[0037] The plow tip 2, in conjunction with the scraper 6, facilitates deep soil turning, scoops up the soil that needs to be turned, and guides the soil to be turned and mixed with the plow blade 1, reducing resistance. With the extension or shortening of the telescopic arm of the hydraulic cylinder 4, the tilt angle of the plow blade 1 on the reinforcing plate 3 is adjusted. When the telescopic arm of the hydraulic cylinder 4 is extended, the angle between the plow blade 1 and the reinforcing plate 3 is increased, which helps to turn the soil deeper. When the telescopic arm of the hydraulic cylinder 4 is shortened, the angle between the plow blade 1 and the reinforcing plate 3 is reduced, which helps to turn the soil at a shallow level.
