Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a ridge spacing adjustment device. Background Art

[0002] A seeder is a machine used to sow seeds such as corn into the ground. When sowing, the seeder diverts the seeds into several feed pipes through a feed hopper, and sows the seeds into the ground through several feed pipes. Before sowing, a ridge spacing adjustment device is usually required to adjust the spacing between several feed pipes so that the seeds can fall into the corresponding sowing troughs.

[0003] The existing ridge spacing adjustment device generally comprises: two installation rods arranged in parallel and at intervals; a plurality of sowing units respectively arranged on the two installation rods; a scissor-fork mechanism arranged between the two installation rods, a driving rod being hinged at the end of the scissor-fork mechanism, and the driving rod being slidably connected with the corresponding sowing unit. By arranging two installation rods, the sowing unit, the scissor-fork mechanism and the driving component, when the driving component drives the scissor-fork mechanism to extend, the driving rod drives the slidable sowing unit to move on the installation rod, and the spacing between adjacent sowing units is synchronously adjusted, so that the spacing between all the sowing units is adjusted at the same time, so as to achieve the effect of quickly adjusting the ridge spacing, and the structure is simple, convenient and practical, and the working efficiency is high;

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-Figure 5 As shown;

[0028] A ridge spacing adjustment device comprises a fixing frame.

[0029] The existing ridge spacing adjustment device generally comprises: two installation rods arranged in parallel and at intervals; a plurality of sowing units respectively arranged on the two installation rods; a scissor-fork mechanism arranged between the two installation rods, a driving rod being hinged at the end of the scissor-fork mechanism, and the driving rod being slidably connected with the corresponding sowing unit. By arranging two installation rods, the sowing unit, the scissor-fork mechanism and the driving component, when the driving component drives the scissor-fork mechanism to extend, the driving rod drives the slidable sowing unit to move on the installation rod, and the spacing between adjacent sowing units is synchronously adjusted, so that the spacing between all the sowing units is adjusted at the same time, so as to achieve the effect of quickly adjusting the ridge spacing, and the structure is simple, convenient and practical, and the working efficiency is high;

[0030] When the existing ridge spacing adjustment mechanism is in use, a number of sowing units are hinged through the scissors-fork mechanism. When the sowing units are close to each other, they will simultaneously drive the sowing units to move on the mounting rod, thereby realizing simultaneous adjustment of the number of sowing units. Since no protective mechanism is arranged outside the sowing units, when external dirt and dust fall onto the scissors-fork mechanism or the mounting rod, it is easy to cause blockage at the connection between the scissors-fork mechanism, or blockage at the connection between the mounting rod and the sowing unit. When it rains, rainwater is easy to fall directly on the scissors-fork mechanism, which may cause the scissors-fork mechanism to rust and affect the flexibility of the connection of the scissors-fork mechanism, thereby reducing the movement efficiency of the sowing units and easily reducing the efficiency of the device in adjusting the ridge spacing of the sowing units. Combined with actual use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a first protective frame and a second protective frame are added to the present application document.

[0031] According to the above content, in order to solve the problem that no protective mechanism is set outside the sowing unit, which may easily lead to blockage of the connection between the scissor-fork mechanism, or blockage of the connection between the mounting rod and the sowing unit, when it rains, the scissor-fork mechanism may be rusted, which reduces the moving efficiency of the sowing unit and easily reduces the efficiency of the device in adjusting the ridge spacing of the sowing unit, the invention also includes a fixed frame 1, a fixed seat 2 is fixedly provided on one side of the fixed frame 1, a first protective frame 3 is fixedly provided on one side of the fixed seat 2, a second protective frame 4 is provided inside the first protective frame 3, two sliders 5 are fixedly provided on the side of the second protective frame 4, and two slide grooves are provided inside the fixed frame 1.

When the two sliding rods 10 are close to or away from each other, the second protection frame 4 will be driven to expand and contract inside the first protection frame 3, so that the first protection frame 3 and the second protection frame 4 are always sealed, and at the same time, it will not affect the movement of the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13. The slider 5 is used to improve the stability of the second protection frame 4 during movement.

The first feed tube 8 and the second feed tube 9 of a certain length are stored in the box 6 and the second sealing box 7 to prevent the first feed tube 8 and the second feed tube 9 from affecting the movement of the first sowing monomer 11 and the second sowing monomer 13, so that the device can protect the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13 without affecting the movement of the scissor mechanism body 14, the first feed tube 8, the second feed tube 9, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13, thereby improving the dustproof, waterproof and anti-collision performance of the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13, thereby increasing the service life of the device and thus improving the ridge spacing adjustment efficiency of the device.

[0033] In an optional embodiment: a side surface of one of the sliding rods 10 is fixedly connected to the interior of the first protective frame 3 , and a side surface of the other sliding rod 10 is fixedly connected to the interior of the second protective frame 4 .

[0034] In this embodiment, the sliding rod 10 is convenient for limiting the first sowing unit 11 and the second sowing unit 13 .

[0035] In an optional embodiment, the fixed end of the first electric telescopic rod 12 is fixedly connected to one side of one of the first sowing monomers 11 , and the telescopic end of the first electric telescopic rod 12 is fixedly connected to one side of the other first sowing monomer 11 .

[0036] In this embodiment, the first electric telescopic rod 12 is convenient for driving the two first sowing units 11 to move closer to or farther from each other.

[0037] In an optional embodiment, the plurality of second sowing units 13 are divided into two groups, and the interiors of the plurality of second sowing units 13 in each group are slidably connected to the side surfaces of the corresponding sliding rods 10 .

[0038] In this embodiment: the second sowing unit 13 is convenient for driving the first feeding pipe 8 and the second feeding pipe 9 to move.

[0039] In an optional embodiment: two second electric telescopic rods 15 are provided at the top of the fixed frame 1, and a mounting frame 16 is provided at the top of the two second electric telescopic rods 15. The bottom ends of the mounting frame 16 are respectively fixedly connected to the fixed ends of the two second electric telescopic rods 15, and the top ends of the fixed frame 1 are respectively fixedly connected to the telescopic ends of the two second electric telescopic rods 15.

[0040] In this embodiment: the second electric telescopic rod 15 is convenient for driving the fixed frame 1 to move up and down.

[0041] In an optional embodiment: four limiting sleeves 17 are fixedly provided on the top of the fixing frame 1 , and limiting grooves are provided inside the four limiting sleeves 17 .

[0042] In this embodiment, the limiting sleeve 17 is convenient for limiting the limiting shaft 18 .

[0043] In an optional embodiment, four limiting shafts 18 are fixedly provided at the bottom end of the installation frame 16 , and the side surfaces of the four limiting shafts 18 are respectively fitted with the insides of the four limiting sleeves 17 .

[0044] In this embodiment, the limiting shaft 18 and the limiting sleeve 17 facilitate improving the stability of the fixed frame 1 when it moves.

[0045] The working principle and use process of the utility model are as follows: the first electric telescopic rod 12 is shortened, so that the two first sowing monomers 11 can be driven to approach each other, so that the two sliding rods 10 can be driven to approach each other, so that the plurality of second sowing monomers 13 can be driven to approach each other, and the scissor mechanism body 14 makes the plurality of first sowing monomers 11 and the second sowing monomers 13 hinged to each other through the plurality of connecting rods. When the first sowing monomers 11 approach each other, the plurality of second sowing monomers 13 on the same sliding rod 10 will move away from each other, so that the spacing between the second sowing monomers 13 can be adjusted at the same time. The first feeding pipe 8 and the second feeding pipe 9 are respectively fixedly arranged in the corresponding first sowing monomers 11 and the second sowing monomers 13. The tops of the first and second feeding tubes 9 are connected to the feed hopper, and the seeds are poured into the first feeding tube 8 and the second feeding tube 9 through the feeding hopper, and the seeds are planted into the sowing groove through the first feeding tube 8 and the second feeding tube 9. When the spacing between the second sowing monomers 13 is adjusted, the ridge spacing between the plurality of first feeding tubes 8 and the plurality of second feeding tubes 9 is adjusted at the same time, and the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13 are protected by the first protective frame 3 and the second protective frame 4 to prevent the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13 from being damaged by impact, and at the same time prevent external soil, dust and water vapor from falling on the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer The surface of the sowing monomer 13 causes the connection between the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13 to be blocked or rusted, reducing the ridge adjustment efficiency of the first sowing monomer 11 and the second sowing monomer 13. When the two sliding rods 10 are close to or away from each other, the second protection frame 4 will be driven to expand and contract inside the first protection frame 3, so that the first protection frame 3 and the second protection frame 4 are always sealed, and at the same time, it will not affect the movement of the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13. The slider 5 is used to improve the stability of the second protection frame 4 during movement, and the first sealing box 6 and the second sealing box 7 are used to limit the first feeding pipe 8 and the second feeding pipe 9. The first feeding pipe 8 and The second feed pipe 9 is a hose, and a certain length of the first feed pipe 8 and the second feed pipe 9 are stored in the first sealing box 6 and the second sealing box 7 to prevent the first feed pipe 8 and the second feed pipe 9 from affecting the movement of the first sowing monomer 11 and the second sowing monomer 13, so that the device is convenient for protecting the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13 without affecting the movement of the scissor mechanism body 14, the first feed pipe 8, the second feed pipe 9, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13, thereby improving the dustproof, waterproof and anti-collision performance of the scissor mechanism body 14, the sliding rod 10, the first sowing monomer 11 and the second sowing monomer 13, so that the service life of the device is increased.Thereby, the ridge spacing adjustment efficiency of the device is improved. The mounting frame 16 is fixed on the side of the seed drill. When the height of the first feed pipe 8 and the second feed pipe 9 is high or too high, the seeding efficiency is easily reduced. When the height of the first feed pipe 8 and the second feed pipe 9 is high, the second electric telescopic rod 15 is started to extend, thereby driving the fixed frame 1 to move downward, thereby driving the first protective frame 3 and the second protective frame 4 to move downward, thereby driving the first feed pipe 8 and the second feed pipe 9 to move downward. When the height of the first feed pipe 8 and the second feed pipe 9 is low, the second electric telescopic rod 15 is started to shorten, thereby driving the fixed frame 1 to move upward, thereby driving the first protective frame 3 and the second protective frame 4 to move upward, thereby driving the first feed pipe 8 and the second feed pipe 9 to move upward. The stability of the fixed frame 1 during movement is improved by the limiting shaft 18 and the limiting sleeve 17, so that the device is easy to adjust the height of the first feed pipe 8 and the second feed pipe 9, and avoid the first feed pipe 8 and the second feed pipe 9 The height is too low or too high affects the seeding efficiency.
