Description

Technical Field

[0001] The utility model relates to the field of agricultural equipment, in particular to a multifunctional auxiliary supporting device for a no-tillage seeder and a seeder. Background Art

[0002] In agricultural production, seeding is a crucial step in the entire production process, performed by a seeder. This process requires, on the one hand, sufficient weight. Heavier machines offer greater operational stability, ensuring the proper furrowing depth and compaction strength for seeding and fertilizing, and thus ensuring that seeding quality meets standards. On the other hand, during use, everyone wants a lighter seeder that meets these requirements while also being able to operate in a suspended manner, allowing for shorter headlands, sufficient seeding coverage, and easier cornering. These two aspects present a conflict. Practice has proven that a heavy seeder cannot function without sufficient weight. However, suspended operation of heavier seeders requires higher lifting capacity from the tractor's suspension, necessitating a higher horsepower tractor. Therefore, to meet these weight requirements, some manufacturers design their seeders for towed operation, bypassing the tractor's suspension mechanism. This solves the problem of insufficient lifting capacity and facilitates transportation. However, for traction-type machines, due to the addition of a traction beam structure, the length of the entire machine is lengthened. During the sowing process, there will be a longer distance at the edge of the field where sowing cannot be done, affecting the sowing area and ultimately affecting grain production. In addition, traction-type operations are inconvenient when turning at the edge of the field, which is time-consuming and labor-intensive, and has a great impact on sowing efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide a multifunctional no-tillage seeder auxiliary support device and a seeder, which, without increasing the supporting power of the tractor, has the advantages of having sufficient weight, a short field head and flexible turning during operation.

[0004] The technical solution of this utility model:

[0005] A multifunctional auxiliary support device for a no-till seeder includes a fixing bolt, a fixed bracket, a movable bracket, a hydraulic cylinder, a support wheel frame, and a support wheel.

DETAILED DESCRIPTION

[0020] To address the problems in the background art, the present invention has invented a multifunctional auxiliary support device for a no-till planter. This auxiliary device can support the entire planter. Without increasing the power of the tractor, it not only meets the advantages of convenient transportation of a traction planter, but also has the advantages of a short headland and flexible turning when operating a suspended planter.

[0021] It should be noted that, in the description of this application, terms such as "inside", "outside", "upper", and "lower" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on this application.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] The seed drill of the present application includes existing structures such as a main beam 14, a rotary tillage component, a fertilizer box, and a seed box. A multifunctional no-till seed drill auxiliary support device is detachably installed on both sides of the main beam. The multifunctional no-till seed drill auxiliary support device 16 includes a fixing bolt 1, a fixed bracket 2, a movable bracket 3, a hydraulic cylinder 4, a support wheel 5, and a support wheel frame 6. One side of the fixed bracket 2 is connected to the fixing bolt 1, and the auxiliary support device of the present application is fixed to the main beam 14 of the seed drill by the fixing bolt. The upper end of the other side of the fixed bracket 2 is connected to the upper end of the hydraulic cylinder 4 via a pin 7, and the lower end of the other side of the fixed bracket 2 is connected to one end of the movable bracket 3 via a pin. The lower end of the hydraulic cylinder 4 is connected to the movable bracket 3 via a pin. The other end of the movable bracket 3 is rotatably connected to the support wheel frame 6, and the support wheel frame 6 is connected to the support wheel 5. The support wheel 5 is used to support the multifunctional no-till seed drill, which can not only ensure the sufficient weight of the seed drill design, but also solve the problem of leaving the headland too long and the inconvenience of turning at the headland during traction operation.

[0024] The movable bracket 3 is detachably connected by a connecting frame 8 and a shaft wall sleeve 9 (common methods such as flange 15 connection, bolt connection, etc. can be adopted). The connecting frame 8 is connected to the fixed bracket 2 and the hydraulic cylinder 4 through a pin shaft. A shaft 10 is fixed to one end of the support wheel frame 6 facing the shaft wall sleeve 9. The shaft is inserted into the shaft wall sleeve 9. A bearing 17 is installed between the shaft and the shaft wall sleeve. The free end of the shaft inserted into the shaft wall sleeve is locked by a nut 18. The end of the shaft is externally threaded and locked with the nut to prevent the shaft from falling off from the shaft wall sleeve.

[0025] Since the shaft on the support wheel frame of the present application can rotate in the shaft wall sleeve, and the support arms on both sides of the support wheel frame have a certain inclination angle with the shaft, the support wheel of the present application can realize a universal function.

[0026] Because it is best to lock the support wheels during long-distance travel, the present application also includes a support wheel locking mechanism 11, which includes two pin holders 12 and a locating pin 13. One pin holder 12 is fixedly connected to the shaft wall sleeve 9, and the other pin holder 12 is fixedly connected to the support wheel frame 6. The locating pin 13 passes through the two pin holders 12 to connect and lock the two pin holders 12. When the locating pin in the support wheel locking mechanism is inserted into the two pin holders and locked, the support wheel does not have a universal function and is used when the seed drill travels long distances. If the locating pin is pulled out of the two pin holders, the support wheel has a universal function and is used when turning at the end of the field during seeding.

[0027] The multifunctional no-till planter incorporates an auxiliary support (lifting) device, described in this application, without increasing the overall length or weight of the machine. This device not only lifts the machine off the ground, addressing the issue of insufficient lifting force from the tractor's hydraulic suspension, but also allows for movement via support wheels mounted underneath, facilitating transport and turning in the field. This device utilizes the tractor's hydraulic output to drive the auxiliary lift cylinder up and down.

[0028] Usage process:

[0029] When the multifunctional no-tillage seeder is operating in the field, the hydraulic cylinder retracts to lift the support wheel up and off the ground, and the seeder operates normally under the control of the tractor hydraulic suspension.

[0030] When the seeder reaches the edge of the field and needs to turn, the hydraulic cylinder extends, the movable bracket rotates downward relative to the fixed bracket, and the support wheels rotate downward to the ground, lifting the seeder. This auxiliary support device, either alone or in conjunction with the tractor's built-in hydraulic suspension, lifts the seeder and bears its weight to perform a turn at the edge of the field. The support wheel locking mechanism is now unlocked.

[0031] When the seeder needs to travel long distances, the hydraulic cylinder extends, the movable bracket rotates downward relative to the fixed bracket, and the support wheel moves downward to the ground, lifting the seeder. The auxiliary support device in this application, alone or in conjunction with the tractor's built-in hydraulic suspension function, can lift the seeder, carrying the weight of the seeder for long distance travel and field turns. Because the tractor moves at high speeds during travel, the support wheel locking mechanism needs to be locked.

[0032] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above and does not deviate from the technical solution of the present invention, and designs a structure and implementation similar to the above embodiment without inventiveness based on the technical essence of the present invention, it shall fall within the scope of protection of the present invention.
