Description

Technical Field

[0001] This utility model relates to the field of grid conversion equipment technology, specifically to a rake mechanism of a ridge-building machine. Background Technology

[0002] In agricultural production, grid-field transformation is a crucial field operation, and ridge construction is the core process. The quality of ridge construction directly affects subsequent irrigation, planting, and other operations. Specifically, ridge construction machines are required in the actual ridge construction process. The disc-type ridge construction machine is a commonly used type. When pulled by a tractor, two sets of rake blades turn over the soil from the left and right sides and convey it towards the center to form the ridge. The disc-type ridge construction machine has advantages such as low resistance and strong adaptability.

[0003] However, most current ridge-building machines adopt a fixed structure design, with a fixed arrangement of rake blades. This results in fixed sizes, widths, and heights of the ridges, making it impossible to adjust them according to actual operational needs. Consequently, they have poor operational adaptability. Although some ridge-building machines have attempted parameter adjustments, their complex structures and inconvenient operation, coupled with low ridge-building efficiency, make it difficult to meet the operational requirements for different specifications of ridges in grid field renovation. Especially in scenarios requiring taller ridges (such as those over 1 meter), existing equipment often fails to meet the operational requirements, thus limiting the quality and efficiency of grid field renovation operations. Utility Model Content

[0004] The purpose of this utility model is to provide a rake mechanism for a ridge-building machine in order to solve the above-mentioned problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a rake mechanism for a ridge-building machine, including two rake components, which are symmetrically arranged on both sides and arranged at a V-shaped angle.

[0007] Each rake assembly includes a rake fixing beam, a rake support shaft, and a rake body. The rake fixing beams on both sides are connected to the connecting arm assemblies on the corresponding sides. The rake fixing beams on both sides are arranged in an inverted V-shape to adjust the size, width, and height of the rake body by means of the cooperation between the rake fixing beams and the connecting arm assemblies.

[0008] The middle position of each rake blade fixing beam is vertically fixed with several rake blade supports by means of clamping and mounting support clamps. The bottom of each rake blade support on the same side is fixedly installed with a bearing support, and the rake blade support shaft on the same side passes through the bearing support on the corresponding side and is rotatably connected to the bearing support. The rake blade body is rotatably installed on the rake blade support shaft at the position outside and between the two rake blade supports.

[0009] Preferably, the connecting arm assembly includes a fixing block, a connecting strut, and a U-shaped bracket. There are two fixing blocks and two U-shaped brackets on the same side. The two fixing blocks are respectively fixedly installed on the corresponding side of the frame beam. The U-shaped brackets are respectively located behind the corresponding fixing blocks. The connecting struts are provided between the fixing blocks and the U-shaped brackets near the outer end of the frame beam. At the same time, the rake blade fixing beam assembly is arranged between the two U-shaped brackets on the corresponding side.

[0010] Preferably, the fixed block and the U-shaped bracket are both fixedly equipped with rotating supports at their close ends, and the two ends of the connecting strut are also fixedly equipped with rotating supports. The two rotating supports of the fixed block and the U-shaped bracket away from the outer end of the frame beam are directly rotatably connected by a vertically inserted pin. The two rotating supports of the fixed block and the U-shaped bracket near the outer end of the frame beam are also rotatably connected to the rotating supports at the corresponding ends of the connecting strut by a vertically inserted pin. This allows the working angle of the rake assembly to be adjusted by horizontally rotating and misaligning the three sets of interconnected rotating supports.

[0011] Preferably, the rake blade fixing beams are rotatably connected to the corresponding U-shaped brackets by means of inserting pins along the longitudinal direction, and the support clamps are tightly clamped to the portion of the rake blade fixing beams located between the two U-shaped brackets on the corresponding side.

[0012] Preferably, the rotatable installation method of the rake blade body and the rake blade support shaft is as follows: the rotation center of the rake blade body is coaxially fixedly configured with a connecting bushing with a built-in bearing, and the rake blade body is coaxially rotatably installed on the outside of the rake blade support shaft through the connecting bushing.

[0013] Preferably, the rake blade fixing beam is a rectangular square tube, each rake blade assembly has two rake blade supports, and the number of rake blade bodies rotatably mounted on the rake blade support shaft is three.

[0014] Preferably, the rake blades are all arc-shaped discs, with the outer arc surfaces of the rake blades on both sides facing outwards and backing away from each other. At the same time, the rake blades on both sides are arranged in a V-shaped angle.

[0015] Preferably, the outer edge of the rake blade is provided with evenly distributed arc-shaped notches to form a tooth-like structure on the outer edge of the rake blade.

[0016] Preferably, the bottom front edge of the rake blade fixing beam extends straight and is fixed with mounting wing plates for installing retaining walls, and the mounting wing plates have openings for passing through at the corresponding positions of the support clamps, so that the support clamps can pass through smoothly for assembly and installation.

[0017] Preferably, the passage openings are all horizontally placed rectangular strip openings, and the distance between the two sides of the passage opening and the edge of the corresponding support clamp is not less than 10cm.

[0018] The above-mentioned embankment building machine's rake mechanism, in practical use, features symmetrically arranged rake blades on both sides at an inverted V-shaped angle. By moving the rake blades with the traction equipment, the soil can be quickly straightened into a straight line, significantly improving soil agglomeration efficiency, ensuring neat embankment formation, and making the embankment building operation simple, efficient, and improving the quality of embankment formation. The embankment building efficiency is more than three times that of existing embankment building equipment. Furthermore, the connecting arm assembly's connecting struts are connected to the fixed block and the rotating support at both ends. The U-shaped bracket is rotated and engaged, and the working angle of the rake blade assembly can be adjusted by the rotational engagement of the directly connected fixing block and the U-shaped bracket via the rotating support. This allows for adjustment of the size and width of the rake body. The adjustment of the rake body size and width is simple and easy to implement, improving the operational adaptability of the rake blade assembly and meeting the operational needs of different field transformation scenarios. Furthermore, by changing the fixed position of the support clamp of the rake blade assembly, the fixed position of the rake blade support on the rake blade fixing beam can be adjusted, thereby changing the rake blade position. The overall height of the component allows for adjustment of the stalk height, a simple and easy-to-implement method that further enhances the operational adaptability of the harrow assembly, meeting the operational needs of different grid conversion scenarios. Furthermore, since the harrow body is rotatably connected to the harrow support shaft via a connecting sleeve with an internal bearing, rotation is flexible, wear is minimal, and the equipment has a long service life. Operation is also convenient, contributing to improved efficiency and quality of grid conversion work. Moreover, because the harrow body is an arc-shaped disc with evenly distributed arc-shaped notches on its outer edge, these notches allow for... The toothed structure formed on the outer edge of the rake blades allows for cutting, tilling, and agglomerating of the soil when the rake blades rotate, thus pushing and compacting the soil into stalks. This helps to further improve the quality of the stalk formation. Furthermore, since the rake blade assembly on both sides is equipped with multiple sets of rake blades, with at least three sets, and the number of rake blades on the rake blade support shaft can be increased or decreased according to operational needs, the stalk width adjustment effect can be further optimized, achieving a maximum stalk height of over 1m. This solves the problem that existing equipment cannot achieve the construction of higher stalks.

[0019] The beneficial effects are as follows: 1. In this utility model, the rake blade components on both sides are symmetrically arranged and arranged in an inverted V-shape. By using the rake blade components to move with the traction equipment, the soil can be quickly straightened into a straight line, which significantly improves the soil aggregation efficiency, ensures that the ridge body is formed in a regular shape, and the ridge construction operation is simple, easy to implement and highly efficient, which improves the quality of the ridge body formation. Moreover, the ridge construction efficiency is more than three times that of existing ridge construction equipment.

[0020] 2. By means of the rotating support at both ends of the connecting arm assembly, the fixed block and the U-shaped bracket are respectively rotated and engaged by the rotating support. At the same time, by means of the rotating support and the fixed block and the U-shaped bracket are directly connected, the working angle of the rake blade assembly can be adjusted, thereby adjusting the size and width of the rake body. The adjustment of the size and width of the rake body is simple and easy to implement, which improves the operational adaptability of the rake blade assembly and can meet the operational needs of different grid conversion scenarios.

[0021] 3. By changing the fixed position of the support clamp of the rake blade assembly, the fixed position of the rake blade support on the rake blade fixing beam can be adjusted, thereby changing the overall height of the rake blade assembly and thus adjusting the height of the rake body. The method of adjusting the height of the rake body is simple and easy to implement, further improving the operational adaptability of the rake blade assembly and meeting the operational needs of different grid conversion scenarios.

[0022] 4. The rake blade body is rotatably connected to the rake blade support shaft through the connecting bushing with the built-in bearing. It rotates flexibly, has little wear, and has a long service life. At the same time, it is easy to operate, which helps to improve the efficiency and quality of grid conversion operations.

[0023] 5. The rake blade is an arc-shaped disc with evenly distributed arc-shaped notches on its outer edge. These notches create a tooth-like structure on the outer edge of the rake blade, which cuts, tills, and gathers the soil as the rake blade rotates. This pushes and compacts the soil into stalks, further improving the quality of the stalk formation.

[0024] 6. The rake blade assembly on both sides is equipped with multiple sets of rake blades, with at least three sets. The number of rake blades on the rake blade support shaft can be increased or decreased according to operational needs, thereby further optimizing the stalk width adjustment effect and achieving a maximum stalk height of over 1m, solving the problem that existing equipment is unable to achieve the construction of higher stalks.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] See Figures 1-8As shown, this utility model provides a rake mechanism for a ridge-building machine, which is included in a ridge-building machine. Specifically, the ridge-building machine includes a frame beam 1, which is horizontally arranged. Connecting arm assemblies 2 are assembled on both front sides of the frame beam 1. Specifically, each connecting arm assembly 2 includes a fixing block 201, a U-shaped bracket 205, and a connecting support rod 204. There are two fixing blocks 201 and two U-shaped brackets 205 on the same side. The two fixing blocks 201 are respectively fixedly installed on the frame beam 1. On the corresponding side, U-shaped brackets 205 are located behind the corresponding fixing blocks 201, and connecting struts 204 are provided between the fixing blocks 201 and U-shaped brackets 205 near the outer end of the frame beam 1. Simultaneously, the rake blade assembly 3 is assembled between the two U-shaped brackets 205 on the corresponding side. Rotary supports 202 are fixedly configured at the ends of the fixing blocks 201 and U-shaped brackets 205 that are close to each other. Rotary supports 202 are also fixedly configured at both ends of the connecting struts 204, and are located away from the outer end of the frame beam 1. The two rotating supports 202 of the fixed block 201 and the U-shaped bracket 205 are directly rotatably connected by vertically inserted pins 203. The two rotating supports 202 of the fixed block 201 and the U-shaped bracket 205 near the outer end of the frame beam 1 are also rotatably connected to the rotating supports 202 at the corresponding ends of the connecting strut 204 by vertically inserted pins 203. This allows the working angle of the rake assembly 3 to be adjusted by horizontally rotating and misaligning the three sets of interconnected rotating supports 202. The purpose of this design is to allow the working angle of the rake assembly 3 to be adjusted by means of the rotating support 202 at both ends of the connecting strut 204 of the connecting arm assembly 2, which is in rotatable engagement with the fixed block 201 and the U-shaped bracket 205 respectively. At the same time, the fixed block 201 and the U-shaped bracket 205 are directly connected and rotated in coordination with the rotating support 202. This allows for adjustment of the size and width of the rake body, making the adjustment of the size and width of the rake body simple and easy to implement, thus improving the operational adaptability of the rake assembly 3.

[0038] See Figures 1-4As shown, a rake blade assembly 3 is assembled at the lower front of the connecting arm assembly 2. The rake blade assemblies 3 on both sides are symmetrically arranged in an inverted V-shape. This arrangement allows the rake blade assemblies 3 to quickly straighten the soil into a straight line by being pulled together by the frame beam 1, connecting arm assembly 2, and rake blade assembly 3, thus achieving the shovel construction operation. The size, width, and height of the shovel can also be adjusted by the cooperation of the connecting arm assembly 2 and the rake blade assembly 3. Specifically, each rake blade assembly 3 includes a rake blade fixing beam 301, a rake blade support shaft 3011, and a rake blade body 306. The rake blade fixing beams 301 on both sides are engaged from bottom to top between two U-shaped brackets 205 on the corresponding sides. The rake blade fixing beams 301 on both sides are arranged in an inverted V-shape, and each rake blade fixing beam 301 is rotatably connected to the corresponding U-shaped bracket 205 by inserting a pin 303 along the longitudinal direction. The fixed beam 301 has several rake blade supports 304 vertically fixed between the two corresponding U-shaped brackets 205 by means of clamping and mounting support clamps 302. The bottom of each rake blade support 304 on the same side is fixedly installed with a bearing support 305, and the rake blade support shaft 3011 on the same side passes through the bearing support 305 on the corresponding side and is rotatably connected to the bearing support 305. Rake blade bodies 306 are rotatably installed on the rake blade support shaft 301 at the positions outside and between the two rake blade supports 304. The purpose of this arrangement is that by changing the fixed position of the support clamps 302 of the rake blade assembly 3, the fixed position of the rake blade supports 304 on the rake blade fixed beam 301 can be adjusted, thereby changing the overall height of the rake blade assembly 3, thus realizing the adjustment of the height of the rake blade body. The method of adjusting the height of the rake blade body is simple and easy to implement, further improving the operational adaptability of the rake blade assembly 3.

[0039] See Figures 1-8As shown, the following optimizations have been made to this application. Specifically, a traction connecting seat 101 for connecting to the traction position of a tractor or other power equipment is fixedly configured on the top surface of the middle part of the frame beam 1. Lifting connecting seats 102 for connecting to the lifting drive position of a tractor are fixedly configured on both sides of the traction connecting seat 101 at the rear of the frame beam 1. This configuration facilitates the movement of the frame beam 1, connecting arm assembly 2, and rake blade assembly 3 together after connecting to the traction position of a tractor or other power equipment via the traction connecting seat 101. It also facilitates the lifting and lowering of the frame beam 1, connecting arm assembly 2, and rake blade assembly 3 together after connecting to the lifting drive position of a tractor via the lifting connecting seat 102. Optionally, the fixing block 201 has fixing holes 206 at the front and rear positions below the frame beam 1 for installing clamps from top to bottom and fixing them to the frame beam 1. This allows the fixing block 201 to be assembled and installed at the bottom of the frame beam 1 by adding clamps, thereby achieving the fixed assembly of the connecting arm assembly 2 at the rear of the frame beam 1. Furthermore, all rotary supports 202 are multi-layered laminated rotary supports, which improves the rotational stability and cantilever load-bearing reliability after the rotary support 202 is rotated.

[0040] See Figures 1-8 As shown, the bottom front edge of the rake blade fixing beam 301 extends straight and is fixed with mounting wing plates 309 for installing retaining walls. The mounting wing plates 309 have passage openings 308 at the corresponding positions of the support clamps 302, so that the support clamps 302 can pass through smoothly for assembly. This design facilitates the installation of external retaining walls using the mounting wing plates, making it easier to shield and protect the rake blades 306 and improve safety. Furthermore, the passage openings 308 are all horizontal rectangular openings, and the distance between the two sides of the passage openings 308 and the edges of the corresponding support clamps 302 is not less than 10cm. The reason for this design is that the passage openings 308 allow the support clamps 302 to pass through smoothly and be tightly installed on the outside of the rake blade fixing beam 301. At the same time, the passage openings 308 have sufficient width to allow the support clamps 302 to move on the rake blade fixing beam 301 and change their installation position, thereby adjusting the position and height of the rake blades 306. Alternatively, the rotational installation method of the rake blade body 306 and the rake blade support shaft 3011 is as follows: the rotation center of the rake blade body 306 is coaxially fixed with a connecting bushing 3010 containing a built-in bearing, and the rake blade body 306 is coaxially rotatably installed on the outside of the rake blade support shaft 3011 through the connecting bushing 3010. The advantage of this setting is that, since the rake blade body 306 is rotatably connected to the rake blade support shaft 3011 through the connecting bushing 3010 containing the built-in bearing, the rake blade body 306 can rotate flexibly, with less wear, a longer service life of the equipment, and convenient operation, which is conducive to improving the efficiency and quality of grid conversion operations.

[0041] See Figures 1-8 As shown, specifically for the rake blade assembly 3, a more detailed optimization is as follows: the rake blade fixing beam 301 is a rectangular square tube, which ensures that the rake blade fixing beam 301 has good and stable structural strength, facilitates mass production, and allows the support clamp 302 to be stably and tightly installed on the outside of the rake blade fixing beam 301. Alternatively, each rake blade assembly 3 may have two rake blade supports 304 and three rake blade bodies 306 rotatably mounted on the rake blade support shaft 3011. With this configuration, since multiple sets of rake blade bodies 306 are provided on both sides of the rake blade assembly 3, and the number of rake blade bodies 306 on the rake blade support shaft 3011 can be increased or decreased according to operational needs, the stalk width adjustment effect can be further optimized, achieving a maximum stalk height of over 1m, thus solving the problem that existing equipment cannot achieve the construction of higher stalks.

[0042] See Figures 1-8 As shown, the rake discs 306 are all arc-shaped discs. The outer arc surfaces of the rake discs 306 on both sides are set outwards and away from each other. The rake discs 306 on both sides are arranged at a V-shaped angle. This arrangement is designed so that, with the rake discs 306 moving with the external traction equipment and rolling themselves, the soil can be quickly straightened into a straight line, significantly improving soil agglomeration efficiency and ensuring the neatness of the rake body formation. Optionally, the outer edges of the rake discs 306 are evenly distributed with arc-shaped notches 307 to form a toothed structure on the outer edges of the rake discs 306. The advantage of this arrangement is that, when the rake discs 306 rotate, they can cut, till, and agglomerate the soil, pushing and compacting it into rakes, further improving the quality of the rake body formation.

[0043] With the above structure, in practical use, because rake blade assemblies 3 are respectively assembled on both sides of the frame beam 1 via connecting arm assemblies 2, and the rake blade assemblies 3 on both sides are symmetrically arranged in an inverted V-shape, the frame beam 1, connecting arm assemblies 2, and rake blade assemblies 3 can be moved together by connecting external traction equipment. This allows the rake blade assemblies 3 to quickly straighten the soil into a straight line, significantly improving soil agglomeration efficiency, ensuring regular ridge formation, and making the ridge construction operation simple, easy to implement, and highly efficient. This improves the quality of ridge formation, and the ridge construction efficiency is more than three times that of existing embankment construction equipment. Furthermore, due to the connecting arm assemblies... The connecting strut 204 of component 2 is connected to the fixed block 201 and the U-shaped bracket 205 at both ends by means of a rotating support 202. Simultaneously, the fixed block 201 and the U-shaped bracket 205, connected by the rotating support 202, allow adjustment of the working angle of the rake assembly 3, thereby adjusting the size and width of the rake body. This adjustment is simple and easy to implement, improving the operational adaptability of the rake assembly 3 and meeting the operational needs of different field transformation scenarios. Furthermore, by changing the fixed position of the support clamp 302 of the rake assembly 3, the position of the rake support 304 within the rake blades can be adjusted. The fixed position on the fixed beam 301 allows for changes in the overall height of the rake assembly 3, thereby adjusting the height of the rake body. This adjustment is simple and easy to implement, further enhancing the operational adaptability of the rake assembly 3 and meeting the operational needs of different grid conversion scenarios. Since the rake body 306 is rotatably connected to the rake support shaft 3011 via a connecting sleeve 3010 with built-in bearings, it rotates flexibly, experiences minimal wear, and has a long service life. It is also easy to operate, which helps improve the efficiency and quality of grid conversion operations. Furthermore, because the rake body 306 is an arc-shaped disc with evenly distributed arc-shaped notches 307 on its outer edge, it utilizes… The evenly distributed arc-shaped notches 307 on the outer edge of the rake blade body 306 can form a tooth-like structure on the outer edge of the rake blade body 306, so that when the rake blade body 306 rotates, it can cut, till and gather the soil, and push and compact the soil into stalks, which helps to further improve the quality of stalk formation. Since multiple sets of rake blade bodies 306 are provided on both sides of the rake blade assembly 3, and the number of rake blade bodies 306 on the rake blade support shaft 3011 can be increased or decreased according to the operation needs, the stalk width adjustment effect can be further optimized, and the maximum stalk height can reach more than 1m, solving the problem that existing equipment is difficult to build tall stalks.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
