According to the pull-type field-flattening furrow opener, when the pull-type field-flattening furrow opener is used and the angle of the rotating rod needs to be adjusted, the two hand-twisted screw rods are rotated at the same time, so that the two movable sleeves are matched with the two guide rods and move in the direction away from the supporting seat at the same time, a plurality of teeth are separated from the gear rings clamped with the teeth respectively, and the angle of the rotating rod is adjusted. Therefore, the two ends of the rotating rod can rotate on the supporting seat to adjust the angle, so that the angles of the plough shares can be synchronously adjusted, and ditches with different depths can be conveniently formed in a flat field.

Description

Technical Field

[0001] This utility model belongs to the field of trenching technology, specifically relating to a trailer-mounted leveling trencher. Background Technology

[0002] A trailer-mounted ditcher is an agricultural machine primarily used for tilling and ditching operations. Trailed to the back of a tractor, it effectively digs and excavates soil in farmland, suitable for irrigation, drainage, and other agricultural needs.

[0003] Existing trailer-mounted ditchers for leveling fields have the following drawbacks during use:

[0004] The fixed distance between the multiple plowshares on the ditch opener means that only multiple ditches with a fixed spacing can be opened, which cannot meet the needs of opening multiple ditches with different spacing. Secondly, the angle of the multiple plowshares cannot be adjusted at the same time, which means that only ditches with a fixed depth can be opened, thus limiting the scope of use. Therefore, a trailer-mounted ditch opener is needed. Utility Model Content

[0005] The purpose of this invention is to provide a trailer-mounted field leveling and ditching device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a towable ditching tool for leveling fields, comprising a mounting frame with an H-shaped vertical cross-section, support seats fixed to both side walls of the mounting frame via connecting arms, a rotating rod rotatably connected between the two support seats, key strips fixed to the outer perimeter of the rotating rod, and multiple equidistant displacement sleeves slidably fitted onto the four key strips and the outer perimeter of the rotating rod, each displacement sleeve having a plowshare fixed to its outer wall; further comprising a synchronous adjustment and positioning component, the synchronous adjustment and positioning component being mounted on the two support seats and connected to the multiple displacement sleeves and the rotating rod.

[0007] In a preferred embodiment, the synchronous adjustment and positioning component includes two symmetrically arranged guide rods that are movably inserted into the back of both support seats, and the rear ends of the two guide rods on the same side are fixed to the same movable sleeve with a U-shaped cross-section.

[0008] In a preferred embodiment, both movable sleeves are threaded with hand-tightening screws at their midpoints, and one end of each hand-tightening screw is rotatably connected to the back of the support base.

[0009] In a preferred embodiment, an arc-shaped groove is provided in the middle of the front side of the two movable sleeves on opposite sides. Multiple teeth arranged in an array along the shape of the arc-shaped groove are fixed in each of the two arc-shaped grooves. Toothed rings are fixed to the outer sides of the extensions at both ends of the rotating rod. Both toothed rings engage with multiple teeth on the same side.

[0010] In a preferred embodiment, a connecting plate is fixedly connected between the two movable sleeves, and a plurality of inserts arranged in an equidistant array are fixedly connected to one side wall of the connecting plate facing the rotating rod.

[0011] In a preferred embodiment, each of the displacement sleeves has multiple insertion holes arranged in a ring array on its outer side, and the insertion post is inserted into the insertion hole.

[0012] Compared with the prior art, the towable ditcher provided by this utility model has at least the following beneficial effects:

[0013] In this invention, when using the towable leveling and ditching tool, to adjust the angle of the rotating rod, both hand-tightening screws can be turned simultaneously. This causes both moving sleeves, aligned with the two guide rods, to move away from the support base. This disengages multiple teeth from their corresponding gear rings, allowing the rotating rod to be adjusted on the support base. This enables simultaneous adjustment of multiple plowshare angles, facilitating the creation of ditches of varying depths in leveled fields. The tool has a wide range of applications. Furthermore, as the multiple teeth disengage from their corresponding gear rings... The corresponding insert will disengage from the insertion hole on the outside of the corresponding displacement sleeve, so that each displacement sleeve can drive the plowshare to adjust the distance between each pair on the rotating rod. After adjustment, by simultaneously turning the two hand screws in reverse, multiple teeth will re-engage with the gear ring, and the corresponding insert will be inserted into the corresponding insertion hole on the outside of the displacement sleeve. This facilitates the synchronous fixing of angle and displacement distance adjustment, greatly improving the portability of the towable leveling ditch opener and enabling it to meet the ditching work of multiple ditches with different spacings, further expanding its application range.

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments.

[0020] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Example

[0023] The fixed distance between the multiple plowshares 16 on the ditch opener means that only multiple ditches with a fixed spacing can be opened, which cannot meet the ditching work of multiple ditches with different spacing. Secondly, the angle of the multiple plowshares 16 cannot be adjusted at the same time, which means that only ditches with a fixed depth can be opened, thus limiting the scope of use.

[0024] For this purpose, please refer to Figure 1-4 This utility model provides a towable leveling and ditching tool, comprising: a mounting frame 1 with an H-shaped vertical cross-section; support seats 12 are fixedly connected to both sides of the mounting frame 1 via connecting arms 11; a rotating rod 13 is rotatably connected between the two support seats 12; key strips 14 are fixedly connected to the outer perimeter of the rotating rod 13; multiple displacement sleeves 15 are slidably sleeved on the four key strips 14 and the outer perimeter of the rotating rod 13; and a plowshare 16 is fixedly connected to the outer wall of each displacement sleeve 15; it also includes a synchronous adjustment and positioning component 2, which is installed on the two support seats 12 and connected to the multiple displacement sleeves 15 and the rotating rod 13.

[0025] The key bar 14 is designed so that the displacement sleeve 15 can only move laterally on the rotating rod 13 to adjust the spacing, and cannot rotate on the rotating rod 13.

[0026] Further as Figure 1-4 As shown, it is worth noting that, in order to fix the rotating rod 13 after the angle adjustment and also to fix the displacement adjustment sleeves 15, a synchronous adjustment positioning component 2 is provided, including two symmetrically arranged guide rods 22 that are movably inserted into the back of both support seats 12. The rear ends of the two guide rods 22 on the same side are fixedly connected to the same U-shaped movable sleeve 21. The middle of each movable sleeve 21 is threaded with a hand-tightening screw 23, and one end of each hand-tightening screw 23 is rotatably connected to the back of the support seat 12. Both of the two opposite side walls have arc-shaped grooves in the middle of their front sides. Multiple teeth 24 arranged in an array along the shape of the arc-shaped grooves are fixed in both arc-shaped grooves. Gear rings are fixed to the outer sides of the extensions at both ends of the rotating rod 13. Both gear rings engage with multiple teeth 24 on the same side. A connecting plate 25 is fixed between the two moving sleeves 21. Multiple insertion posts 27 arranged in an equidistant array are fixed to the side wall of the connecting plate 25 facing the rotating rod 13. Multiple insertion holes 26 arranged in a ring array are opened on the outer side of each displacement sleeve 15. The insertion posts 27 are inserted into the insertion holes 26.

[0027] The depth of the insertion hole 26 is smaller than the length of the insertion post 27, and the back of both support bases 12 is provided with guide grooves 221 that cooperate with the guide rod 22.

[0028] In summary: When using this trailer-mounted leveling and ditching tool, if the angle of the rotating rod 13 needs to be adjusted, both hand-tightening screws 23 can be rotated simultaneously. This causes both moving sleeves 21 to engage with the two guide rods 22 and move away from the support base 12. This disengages multiple teeth 24 from their corresponding gear rings, allowing the two ends of the rotating rod 13 to rotate and adjust their angles on the support base 12. This facilitates the simultaneous adjustment of the angles of multiple plowshares 16, making it easier to create ditches of different depths in leveled fields. It has a wide range of applications. Furthermore, as the multiple teeth 24 disengage from their corresponding gear rings, the corresponding… The insert 27 will disengage from the insertion hole 26 on the outside of the corresponding displacement sleeve 15, so that each displacement sleeve 15 can drive the plowshare 16 to adjust the distance between each pair on the rotating rod 13. After adjustment, by simultaneously rotating the two hand screws 23 in reverse, the multiple teeth 24 will re-engage with the gear ring, and the insert 27 at the corresponding position will be inserted into the corresponding insertion hole 26 on the outside of the displacement sleeve 15. This facilitates the synchronous fixing of angle and displacement distance adjustment, greatly improves the portability of the towable leveling ditch opener, and can meet the ditching work of multiple ditches with different spacing, further expanding the scope of application.
