Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a standardized farmland ditching device. Background Technology

[0002] In agricultural planting, ditching devices are often used to dig ditches in farmland. Crop seeds are then planted in the dug ditches and covered with soil to facilitate germination and growth.

[0003] Existing ditching devices are typically attached to agricultural machinery for ditching. The machinery pulls the ditching plow, which then moves to create furrows. However, in actual planting, the width of the furrows often varies depending on the crop. While most existing devices can adjust the furrow spacing, they cannot adjust the furrow width. This necessitates changing the ditching plow to different sizes depending on the crop, limiting the device's applicability and hindering rapid ditching efficiency. Utility Model Content

[0004] This utility model proposes a standardized farmland ditching device to solve the problem that existing ditching devices cannot adjust the width of the ditch.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a standardized farmland ditching device, comprising a crossbeam, a traction connecting frame mounted on the crossbeam, and N ditching plow assemblies, where N ≥ 1. Each of the N ditching plow assemblies includes a mounting frame, a connecting rod connected to the bottom end of the mounting frame, and fasteners for mounting and fixing the mounting frame to the crossbeam. A side plate is mounted on one side of the connecting rod, and a mounting plate is mounted on the bottom end of the connecting rod. A plowshare is detachably mounted on the mounting plate, and a first mud guide plate and a second mud guide plate are respectively hinged to both sides of the side plate.

[0006] An adjusting component is provided on the side of the connecting rod opposite to the side plate to rotate and adjust the first and second mud guide plates. The adjusting component includes a rotating rod, both ends of which are fitted with threaded rods. A first connecting sleeve and a second connecting sleeve are screwed to the outside of the two threaded rods respectively. One end of the first connecting sleeve is hinged to the inner wall of the first mud guide plate, and one end of the second connecting sleeve is hinged to the inner wall of the second mud guide plate.

[0007] Preferably, a telescopic adjustment component is provided between the connecting rod and the mounting bracket, and the telescopic adjustment component includes an extension rod integrally formed on the top of the connecting rod. The extension rod has screw holes evenly distributed along its height direction. The mounting bracket has a storage cavity for inserting the extension rod inside, and a fixing bolt is screwed onto one side of the mounting bracket. The fixing bolt can be screwed into the corresponding screw hole.

[0008] Preferably, the fastener includes a base plate, a top plate, and fastening bolts for screwing the base plate and the top plate together. The mounting bracket has a recess for mounting the base plate, and a through cavity is formed between the base plate and the top plate for the crossbeam to pass through.

[0009] Preferably, a fixing frame is also installed on the side wall of the connecting rod, and one end of the fixing frame is sleeved on the rotating rod.

[0010] Preferably, the plowshare is screwed with countersunk bolts to secure it to the mounting plate.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] (1) By setting the adjustment component, the opening angle between the first guide plate and the second guide plate can be adjusted according to the width requirement of the trench during trenching, so that the opening angle between the first guide plate and the second guide plate meets the width of the trench, thereby enabling the trenching device to excavate trenches of different widths, which can meet the planting needs of different crops, and thus greatly increases the applicability of the trenching device.

[0028] 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.

[0029] This utility model provides, for example Figures 1-4 as well as Figure 6The illustrated standardized farmland ditching device includes a crossbeam 1, a traction connecting frame 2 mounted on the crossbeam 1, and N ditching plow assemblies 3, where N ≥ 1. Each of the N ditching plow assemblies 3 includes a mounting frame 31, a connecting rod 34 connected to the bottom end of the mounting frame 31, and fasteners 32 for mounting and fixing the mounting frame 31 to the crossbeam 1. A side plate 35 is mounted on one side of the connecting rod 34, and a mounting plate 310 is mounted on the bottom end of the connecting rod 34. A plowshare 38 is detachably mounted on the mounting plate 310. A first mud guide plate 36 and a second mud guide plate 37 are respectively hinged to both sides of the side plate 35. Specifically, in this embodiment, for illustrative purposes, there are 3 ditching plow assemblies 3, but in actual use, there can be 1, 2, 4, or 6, etc. The specific design depends on the actual ditching requirements and is not limited here.

[0030] An adjusting member 33 is provided on the side of the connecting rod 34 opposite to the side plate 35 to rotate and adjust the first mud guide plate 36 and the second mud guide plate 37. The adjusting member 33 includes a rotating rod 332, and threaded rods 335 are installed at both ends of the rotating rod 332. A first connecting sleeve 333 and a second connecting sleeve 334 are respectively screwed to the outside of the two threaded rods 335. One end of the first connecting sleeve 333 is hinged to the inner wall of the first mud guide plate 36, and one end of the second connecting sleeve 334 is hinged to the inner wall of the second mud guide plate 37.

[0031] Specifically, regarding the aforementioned fastener 32, such as Figures 1-3 As shown, the fastener 32 includes a base plate 321, a top plate 322, and a fastening bolt 323 for screwing the base plate 321 and the top plate 322 together. The mounting bracket 31 has a recess for mounting the base plate 321, and a through cavity is formed between the base plate 321 and the top plate 322 for the crossbeam 1 to pass through.

[0032] As described above, when ditching farmland, the ditching device can be connected to external agricultural machinery via the traction connecting frame 2. Then, the external agricultural machinery will pull the ditching plow assembly 3 to move along the farmland. At this time, the plowshare 38 will be used to ditch the farmland. Then, the first mud guide plate 36 and the second mud guide plate 37 will guide the soil to both sides of the ditch along the excavated ditch, thereby realizing the ditching of the farmland.

[0033] Furthermore, during the trenching process, the first guide plate 36 and the second guide plate 37 can be opened and closed using the adjusting component 33 according to the required trench width. The specific adjustment steps are as follows:

[0034] Rotating the rotating rod 332 causes the threaded rods 335 at both ends to rotate. The two threaded rods 335 then drive the first connecting sleeve 333 and the second connecting sleeve 334 to move relative to each other. Simultaneously, the first connecting sleeve 333 and the second connecting sleeve 334 respectively drive the first guide plate 36 and the second guide plate 37 to rotate, causing the opening angle between the first guide plate 36 and the second guide plate 37 to increase or decrease until the opening angle meets the required trench width. Then, due to the self-locking function of the threads, the first connecting sleeve 333 and the second connecting sleeve 334 remain fixed to the two threaded rods 335, stably supporting the first guide plate 36 and the second guide plate 37. This ensures that the first guide plate 36 and the second guide plate 37 stably guide the soil out of the trench, allowing the trenching device to excavate trenches of different widths to meet the planting needs of different crops. This greatly increases the applicability of the trenching device and facilitates efficient trenching in farmland.

[0035] Furthermore, such as Figure 2 and Figure 3 As shown, a fixing frame 331 is also installed on the side wall of the connecting rod 34, and one end of the fixing frame 331 is sleeved on the rotating rod 332. Specifically, one end of the fixing frame 331 is provided with two collars, and the rotating rod 332 is rotatably installed in the two collars, thereby ensuring the rotation of the rotating rod 332 on the basis of stable support, which facilitates the rotation adjustment of the first guide plate 36 and the second guide plate 37.

[0036] Furthermore, in order to make the plowshare 38 detachable and facilitate its replacement, such as... Figure 1 and Figure 2 As shown, the plowshare 38 is screwed with countersunk bolts 39 that secure it to the mounting plate 310.

[0037] Additionally, in one embodiment, such as Figure 3 , Figure 5 and Figure 7 As shown, a telescopic adjustment component 311 is also provided between the connecting rod 34 and the mounting bracket 31. The telescopic adjustment component 311 includes an extension rod 3114 integrally formed on the top of the connecting rod 34. The extension rod 3114 has screw holes 3112 evenly distributed along its height direction. The mounting bracket 31 has a storage cavity 3113 for inserting the extension rod 3114 inside. A fixing bolt 3111 is screwed onto one side of the mounting bracket 31. The fixing bolt 3111 can be screwed into the corresponding screw hole 3112.

[0038] During the process of ditching farmland, the height of the plowshare 38 can be adjusted according to the required depth of the ditching, and the specific adjustment steps are as follows:

[0039] First, remove the fixing bolt 3111 from the mounting bracket 31. Then, pull the connecting rod 34 downwards, causing the connecting rod 34 to move the extension rod 3114 out of the receiving cavity 3113 inside the mounting bracket 31 (e.g., Figure 7 As shown), the connecting rod 34 and the mounting frame 31 are extended to lower the height of the plowshare 38, the first guide plate 36 and the second guide plate 37 until the required ditching depth of the farmland is met. Then, the fixing bolt 3111 is screwed into the corresponding screw hole 3112 to screw the extension rod 3114 and the mounting frame 31 to fix the connecting rod 34 and the mounting frame 31. Then, under the traction of the agricultural machinery, the plowshare 38, the first guide plate 36 and the second guide plate 37 are moved to realize the ditching operation of the farmland.

[0040] Similarly, if the height of the plowshare 38, the first mud guide plate 36, and the second mud guide plate 37 needs to be adjusted upwards, the fixing bolt 3111 can be removed from the mounting bracket 31, and the connecting rod 34 can be pushed upwards so that the extension rod 3114 can be inserted into the receiving cavity 3113. Then, the extension rod 3114 and the mounting bracket 31 can be screwed together and fixed by the fixing bolt 3111 to realize the retraction between the connecting rod 34 and the mounting bracket 31, thus completing the height adjustment of the plowshare 38, the first mud guide plate 36, and the second mud guide plate 37.

[0041] In summary, this utility model allows the height of the plowshare 38, the first mud guide plate 36, and the second mud guide plate 37 to be adjusted by the telescopic adjustment component 311, so that the trenching device can adapt to the needs of different trenching depths, thereby improving the practicality of the trenching device and facilitating its use.

[0042] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
