Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a wheeled ditcher. Background Technology

[0002] Furrow openers are commonly used agricultural components, primarily for creating planting furrows during sowing. Common furrow openers include chain openers, disc openers, and moldboard openers. The moldboard opener is a tillage implement that breaks up the plow pan, restores soil structure, improves soil water retention, eliminates some weeds, reduces pests and diseases, levels the surface, and improves the standard of mechanized agricultural operations. During tillage, because the moldboard opener needs to penetrate deep into the soil for turning, to reduce resistance between the plow and the soil, current moldboard openers typically only have support at the front where they break the soil, leaving the rear ends of the plowshares suspended. This rear end is prone to swaying during tillage, affecting operational stability and efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a wheeled ditcher with a reasonable structural design that can ensure the working stability of the moldboard plow and improve the working efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A wheeled furrow opener includes a vertically arranged plowstock and a V-shaped plowstock support, the V-groove of the plowstock facing the plowstock and mounted on the plowstock; a plowshare is provided at the lower end of the plowstock, and the upper end of the plowshare is connected to the lower end of the plowstock support; plowshare plates are symmetrically arranged on both sides of the plowstock support; a support beam extends along a direction away from the plowstock support on the plowstock support, the support beam being located on the symmetry center plane of the plowstock support; a support wheel is provided below the support beam, the support wheel being mounted on the support beam via a hinge bracket; the rotation axis of the support wheel is perpendicular to the symmetry center plane of the plowstock support.

[0006] In the above structure, by installing support wheels on the support beam behind the plow column, the rear of the entire furrow opener can be supported by the support wheels, improving the stability of the furrow opener. At the same time, since the support wheels themselves can rotate, they will not additionally increase the frictional resistance between the furrow opener and the ground.

[0007] Furthermore, the support beam has a vertically integrated lifting and adjusting mechanism, and the hinge bracket is installed on the telescopic end of the lower end of the lifting and adjusting mechanism.

[0008] In this way, the support height of the support wheel can be adjusted through the lifting and adjusting mechanism, thereby adapting to the operation of the trencher at different pitch angles.

[0009] Furthermore, the lifting and adjusting mechanism includes an outer sleeve that is vertically and continuously mounted on the support beam. The lower end of the outer sleeve is axially telescopically fitted with a telescopic tube. There is an axially arranged guide structure between the outer sleeve and the telescopic tube. The upper end of the outer sleeve has a through-hole on its sealing plate. The telescopic tube has a transmission threaded hole coaxially arranged with the limiting hole. An adjusting rod passes through the limiting hole. The middle part of the adjusting rod has a limiting groove that cooperates with the limiting hole, and the end facing the telescopic tube has a threaded rod that cooperates with the transmission threaded hole.

[0010] In this way, the adjusting rod engages with the limiting hole through the limiting groove, allowing the adjusting rod to rotate within the limiting hole without moving axially. Simultaneously, due to the guide structure between the telescopic tube and the outer sleeve, no relative rotation occurs between them. When the adjusting rod is rotated, a threaded drive is formed between the threaded rod and the transmission threaded hole on the telescopic tube, causing the telescopic tube to extend and retract axially within the outer sleeve, thereby achieving the up-and-down adjustment of the hinge bracket.

[0011] Furthermore, the upper end of the threaded rod has a coaxially arranged limiting rod, the diameter of which matches the inner diameter of the limiting hole and is smaller than the diameter of the threaded rod; the adjusting rod includes an operating rod coaxially connected to the limiting rod, the diameter of which is larger than the inner diameter of the limiting hole; the limiting groove is formed at the limiting rod between the threaded rod and the operating rod.

[0012] Furthermore, the upper end of the limiting rod has a threaded section, the lower end of the operating rod has a threaded hole, and a locking nut is fitted onto the threaded section of the limiting rod and connected to the threaded hole of the operating rod.

[0013] In this way, the limit rod is connected to the threaded hole of the operating rod through the threaded section, and the locking nut on the threaded section can be used to lock the operating rod to prevent loosening.

[0014] Furthermore, the outer tube and the telescopic tube are nested rectangular tubes, and the guide structure is the rectangular inner hole of the outer tube.

[0015] Furthermore, a support plate is installed on the hinge bracket, which is parallel to the side of the support wheel. The support plate has a support rod extending away from the plowstock. The end of the support rod has a scraper plate parallel to the axis of the support wheel. There is a scraping gap between the scraper plate and the support wheel.

[0016] Furthermore, the support plate has a strip-shaped hole arranged along the length direction of the support rod, and the support plate is fixed to the hinge bracket by bolts passing through the strip-shaped hole.

[0017] In this way, the installation position of the support plate can be adjusted through the strip hole, thereby changing the sludge scraping gap between the scraper blade and the support wheel.

[0018] Furthermore, the plowshare plate is hinged to the plow support, and the plowshare plate has a connecting seat at a position away from the plow support; a width adjustment mechanism that can adjust the distance between the connecting seat and the support beam is connected.

[0019] In this way, since the two plowshares are respectively hinged to the plow support, and there is a width adjustment mechanism connecting the plowshares and the plow column that can adjust the distance between the connecting seat and the plow column, in the triangle formed by the width adjustment mechanism, the plowshares and the plow column, after the width adjustment mechanism changes the distance between the connecting seat and the plow column, the angle between the plowshares and the plow column also changes, so that the unfolded width of the two plowshares can be adjusted to adapt to different trenching needs.

[0020] Furthermore, the width adjustment mechanism includes a slider and a support rod. The slider is slidably disposed on the support beam along its length. The two ends of the support rod are respectively hinged to the slider and the connecting seat. A locking member for locking the slider is connected between the slider and the support beam.

[0021] By loosening the locking mechanism, the slider support rod can be moved along its length, thus changing the angle between the support rod and the support column. This, in turn, adjusts the opening of the plow plate and changes the width of the trencher. After adjusting to the appropriate width, the slider is fixed to the support column using the locking mechanism, allowing trenching operations to be performed at a fixed width.

[0022] In summary, this utility model has the advantages of reasonable structural design, which can ensure the working stability of the moldboard plow and improve working efficiency. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the embodiments.

[0029] In practical implementation: such as Figures 1 to 7 As shown, a wheeled furrow opener includes a vertically arranged plowstock 1 and a V-shaped plowstock support 2. The V-shaped groove of the plowstock support 2 faces the plowstock 1 and is mounted on the plowstock 1. A plowshare 3 is provided at the lower end of the plowstock 1, and the upper end of the plowshare 3 is connected to the lower end of the plowstock support 2. Plowshare plates 4 are symmetrically arranged on both sides of the plowstock support 2. The plowstock 1 has a support beam 5 extending in a direction away from the plowstock support 2, and the support beam 5 is located on the symmetry center plane of the plowstock support 2. A support wheel 6 is provided below the support beam 5, and the support wheel 6 is mounted on the support beam 5 through a hinge bracket 7. The rotation axis of the support wheel 6 is perpendicular to the symmetry center plane of the plowstock support 2.

[0030] By installing support wheels on the support beam behind the plow column, the rear of the entire furrow opener can be supported, improving the furrow opener's stability. At the same time, because the support wheels themselves can rotate, they do not additionally increase the frictional resistance between the furrow opener and the ground.

[0031] The support beam 5 has a vertically integrated lifting and adjusting mechanism 8, and the hinge bracket 7 is installed on the telescopic end of the lower end of the lifting and adjusting mechanism 8. Specifically, the lifting and adjusting mechanism 8 includes an outer sleeve 81 that is vertically integrated on the support beam 5. The lower end of the outer sleeve 81 is axially telescopically fitted with a telescopic tube 82. There is an axially integrated guide structure between the outer sleeve 81 and the telescopic tube 82. The upper end of the outer sleeve 81 has a through-hole on its sealing plate, and the telescopic tube 82 has a transmission threaded hole coaxial with the limiting hole. An adjusting rod 9 passes through the limiting hole. The middle part of the adjusting rod 9 has a limiting groove 91 that mates with the limiting hole, and the end facing the telescopic tube 82 has a threaded rod 92 that mates with the transmission threaded hole. Figure 6 and Figure 7 As shown, the upper end of the threaded rod 92 has a coaxially arranged limiting rod. The diameter of the limiting rod matches the inner diameter of the limiting hole and is smaller than the diameter of the threaded rod 92. The adjusting rod 9 includes an operating rod 93 coaxially connected to the limiting rod. The diameter of the operating rod 93 is larger than the inner diameter of the limiting hole. A limiting groove 91 is formed at the limiting rod between the threaded rod 92 and the operating rod 93. The upper end of the limiting rod has a threaded section, and the lower end of the operating rod 93 has a threaded hole. A locking nut 94 is fitted onto the threaded section of the limiting rod and connected to the threaded hole of the operating rod 93. In this embodiment, the outer sleeve 81 and the telescopic tube 82 are nested rectangular tubes, and the guide structure is the rectangular inner hole of the outer sleeve 81.

[0032] During assembly, connect the threaded rod to the telescopic tube, then insert the entire telescopic tube and threaded rod into the outer sleeve. Pass the limiting rod on the threaded rod through the limiting hole on the outer sleeve, and install a lock nut on the threaded section of the limiting rod. Next, mate the threaded hole of the operating rod with the threaded section of the limiting rod. After connection, rotate the lock nut towards the operating rod and press it firmly against the end of the operating rod to form an anti-loosening locking structure. For ease of operation, an operating handle is provided at the end of the operating rod. Because the adjusting rod mates with the limiting hole through the limiting groove, the adjusting rod can rotate within the limiting hole without moving axially. Simultaneously, the guide structure between the telescopic tube and the outer sleeve prevents relative rotation between them. When the adjusting rod is rotated, a threaded transmission is formed between the threaded rod and the drive threaded hole on the telescopic tube, causing the telescopic tube to extend and retract axially within the outer sleeve, thereby achieving up-and-down adjustment of the hinge support. Since the support height of the support wheel can be adjusted, it can adapt to the operation of the trencher at different pitch angles.

[0033] In this embodiment, the lifting adjustment mechanism 8 is located in the middle of the support beam 5. The hinge bracket 7 is generally U-shaped and is arranged in a direction away from the plowstock 2. A rotating shaft is fixedly passed through the hinge bracket 7, and the support wheel 6 is rotatably sleeved on the rotating shaft through a bearing. A support plate 10 is installed on the hinge bracket 7, which is parallel to the side of the support wheel 6. The support plate 10 has a support rod 11 extending in a direction away from the plowstock 2. The end of the support rod 11 has a scraper 12 parallel to the axis of the support wheel 6, and there is a scraping gap between the scraper 12 and the support wheel 6. The support plate 10 has a strip-shaped hole along the length of the support rod 11, and the support plate 10 is fixed to the hinge bracket 7 by bolts passing through the strip-shaped hole. In this way, the installation position of the support plate can be adjusted through the strip-shaped hole, thereby changing the scraping gap between the scraper and the support wheel.

[0034] The plowshare plate 4 is hinged to the plow support 2, and a connecting seat 41 is located on the plowshare plate 4 away from the plow support 2. A width adjustment mechanism 13 is connected between the connecting seat 41 and the support beam 5 to adjust the distance between them. Since the two plowshare plates are respectively hinged to the plow support, and the plowshare plate and the plow column are connected by a width adjustment mechanism that adjusts the distance between the connecting seat and the plow column, in the triangle formed by the width adjustment mechanism, the plowshare plate, and the plow column, after the width adjustment mechanism changes the distance between the connecting seat and the plow column, the angle between the plowshare plate and the plow column also changes, so that the unfolded width of the two plowshare plates can be adjusted to adapt to different trenching needs.

[0035] Specifically, the width adjustment mechanism 13 includes a slider 131 and a support rod 132. The slider 131 is slidably disposed on the support beam 5 along the length direction. The two ends of the support rod 132 are respectively hinged to the slider 131 and the connecting seat 41. A locking member 133 for locking the slider 131 is connected between the slider 131 and the support beam 5.

[0036] By loosening the locking mechanism, the slider support rod can be moved along its length, thus changing the angle between the support rod and the support column. This, in turn, adjusts the opening of the plow plate and changes the width of the trencher. After adjusting to the appropriate width, the slider is fixed to the support column using the locking mechanism, allowing trenching operations to be performed at a fixed width.

[0037] The support beam 5 has a strip-shaped hole arranged along its length, and the slider 131 has a threaded hole directly opposite the strip-shaped hole. The locking member 133 is a locking bolt that passes through the strip-shaped hole and connects to the threaded hole. The support beam 5 has a guide groove arranged along its length, and the slider 131 is slidably fitted into the guide groove. The strip-shaped hole is located at the bottom of the guide groove, and the end of the support rod 132 facing the slider 131 has a hinge hole and is rotatably sleeved on the locking member 133. The support beam 5 is made of bent steel plate, and the guide groove is a bent U-shaped groove.

[0038] like Figure 5 As shown, a crossbar 14 is hinged to the upper end of the plowstock 1, and the crossbar 14 is laterally arranged on the symmetrical center plane of the plowstock 2. The front end of the crossbar 14 has a connecting part for agricultural machinery, and the rear end is connected to the plowstock 1 by a pitch adjustment mechanism 15 that can adjust the distance between the two. Specifically, the rear end of the crossbar 14 is hinged to a first hinge shaft 16 arranged laterally, and a second hinge shaft 17 is hinged to the support beam 5. The first hinge shaft 16 has a threaded hole that passes through radially, and the second hinge shaft 17 has a through hole arranged radially. The pitch adjustment mechanism 15 is a screw that fits into the threaded hole of the first hinge shaft 16. One end of the screw has a connecting rod with a diameter smaller than that of the screw, and passes through the through hole of the second hinge shaft 17. A limit block is installed at the end of the connecting rod, so that the screw can be rotatably connected to the through hole of the second hinge shaft 17. The other end of the screw has a handle.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
