Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, in particular to a ditching device for agricultural machinery. Background Art

[0002] Agricultural machinery refers to various machines used in the process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. The fertilizer furrowing device is one of the indispensable parts of sowing and intertillage fertilization machinery. Its main function is to break the soil bed during sowing or intertillage to create conditions for the application of fertilizer, so that the application of fertilizer can meet the depth and position required by agronomy. The existing fertilizer furrowing devices are of three types: shovel type, slide knife type and disc type.

[0003] For example, a disc fertilizing furrowing device with publication number CN215774209U adopts a single disc furrowing device. Although this furrowing device can quickly open a furrow on a soil pile, the structure of the furrow is relatively thin and multiple furrow expansion operations are required. The furrowing efficiency is low. In order to solve the above problems, a furrowing device for agricultural machinery is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a ditching device for agricultural machinery in order to solve the above problems.

[0005] The technical solution adopted by the utility model is as follows: a ditching device for agricultural machinery, comprising:

[0006] A fixed rod, with two tire racks welded to its rear side, and tires are rotatably connected to the lower ends of the tire racks;

[0007] A fixing seat is fixedly installed on the outer wall of the rear side of the fixing rod by bolts, a lower beam is fixedly installed on the lower end of the fixing seat, connecting rods are fixedly installed on both front and rear ends of one side of the lower beam, auxiliary wheels are rotatably connected to the lower ends of the two connecting rods, a connecting seat is fixedly installed on the lower wall of the other end of the fixing seat, the first ditching plate is rotatably connected to the front and rear sides of the inner wall of the connecting seat, a connecting plate is hinged on the lower wall of the lower beam close to the connecting rod, and the second ditching plate is rotatably connected to the front and rear sides of the lower end of the connecting plate.

[0008] Through the above technical solution, the ditching device is connected to the agricultural machinery. When the agricultural machinery drives the ditching device to move, the tire drives the fixed rod to move. At this time, the two first ditching discs contact the ground to open a relatively fine groove. After the initial ditching, when the two second ditching discs pass through the newly opened fine groove, the second ditching discs expand the fine groove outward to make it gradually larger. By setting up two ditching mechanisms, the ditching process is completed in one step, which greatly improves the ditching efficiency.

[0009] In a preferred embodiment, the angle between the two first trenching discs is smaller than the angle between the two second trenching discs.

[0010] In a preferred embodiment, a hanging frame is hingedly connected to the front side of the fixing rod.

[0011] Through the above technical solution, the trenching device is connected to the agricultural machinery through the hanging frame.

[0012] In a preferred embodiment, a groove is formed on the upper wall of the lower beam on one side close to the connecting plate.

[0013] Through the above technical solution, seeds or fertilizers can be poured into the groove during the trenching process.

[0014] In a preferred embodiment, the two first trenching discs are located between the two auxiliary wheels.

[0015] In a preferred embodiment, the number of the fixing seats is two, which are respectively fixed to the left and right ends and the middle of the rear side of the fixing rod by bolts, and the distance between two adjacent fixing seats is the same.

[0016] Through the above technical solution, the trenching device can open three trenches at one time.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows: the utility model provides a ditching device for agricultural machinery.

[0018] The ditching device is connected to the agricultural machinery. When the agricultural machinery drives the ditching device to move, the tire drives the fixed rod to move. At this time, the two first ditching discs contact the ground to open a relatively fine groove. After the initial ditching, when the two second ditching discs pass through the newly opened fine groove, the second ditching discs expand the fine groove outward to make it gradually larger. By setting up two ditching mechanisms, the ditching process is completed in one step, which greatly improves the ditching efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example:

[0026] A ditching device for agricultural machinery, comprising:

[0027] A fixed rod 1 has two tire racks 2 welded to its rear side, and a tire 3 is rotatably connected to the lower end of the tire rack 2 to connect the trenching device to the agricultural machine. When the agricultural machine drives the trenching device to move, the fixed rod 1 is driven to move by the tire 3;

[0028] A hanging frame 12 is hingedly connected to the front side of the fixed rod 1, and the ditching device is connected to the agricultural machine through the hanging frame 12;

[0029] A fixing seat 4 is fixedly installed on the outer wall of the rear side of the fixing rod 1 by bolts. There are two fixing seats 4, which are respectively fixedly installed on the left and right ends and the middle part of the rear side of the fixing rod 1 by bolts, and the distance between two adjacent fixing seats 4 is the same, so that the ditching device can dig three grooves at one time. A lower beam 5 is fixedly installed on the lower end of the fixing seat 4, and connecting rods 6 are fixedly installed on the front and rear ends of one side of the lower beam 5. The lower ends of the two connecting rods 6 are rotatably connected to auxiliary wheels 7. A connecting seat 8 is fixedly installed on the lower wall of the other end of the fixing seat 4, and the front and rear sides of the inner wall of the connecting seat 8 are rotatably connected to the first ditching disc 9. The two first ditching discs 9 are located between the two auxiliary wheels 7. A connecting plate 10 is hingedly connected to the lower wall of the lower beam 5 close to the connecting rod 6, and a groove is provided on the upper wall of the lower beam 5 close to the connecting plate 10. Seeds or fertilizers can be poured into the groove during the ditching process.

[0030] The second ditching discs 11 are rotatably connected to the front and rear sides of the lower end of the connecting plate 10. The angle between the two first ditching discs 9 is smaller than the angle between the two second ditching discs 11. The two first ditching discs 9 contact the ground to open a relatively fine groove. After the initial ditching, when the two second ditching discs 11 pass through the newly opened fine groove, the fine groove is expanded outward by the second ditching discs 11 to make it gradually larger. By setting up two ditching mechanisms, the ditching process is completed in one step, which greatly improves the ditching efficiency.

[0031] Working principle:

[0032] The ditching device is connected to the agricultural machinery. When the agricultural machinery drives the ditching device to move, the tire 3 drives the fixed rod 1 to move. At this time, the two first ditching discs 9 contact the ground to open a relatively fine groove. After the initial ditching, when the two second ditching discs 11 pass through the fine groove just opened, the fine groove is expanded outward by the second ditching discs 11 to make it gradually larger. By setting up two ditching mechanisms, the ditching process is completed in one step, which greatly improves the ditching efficiency.
