Description

Technical Field

[0001] The utility model relates to the technical field of wheat planting, in particular to a sowing device for wheat planting. Background Art

[0002] Wheat is an important food crop of the genus Triticum in the Poaceae family. Wheat is a cereal crop widely grown around the world. Wheat is divided into winter wheat and spring wheat. Winter wheat is generally sown from September to October, and spring wheat is generally sown after the Spring Festival. With the development of mechanization, wheat planting often uses special sowing equipment for efficient sowing.

[0003] Chinese patent document CN220897158U relates to a sowing device for wheat planting. In view of the problems that the existing seed mixing and sowing cannot be integrated and the soil covering is incomplete, the following scheme is proposed, which includes a sowing mechanism, and the sowing mechanism for wheat seeds includes a storage component and a leakage component, and the storage component and the leakage component are fixedly connected to the frame. The utility model is provided with a mixing chamber and a storage chamber, and a pull-out partition is provided between the mixing chamber and the storage chamber to separate them. While the sowing device is performing sowing operations, the wheat seeds can also be mixed, and there is no need to manually perform a large amount of mixing treatment on the wheat seeds in advance; the trenching shovel provided is composed of a bent front end shovel, a bent middle shovel and a bent tail shovel, which can bend the soil in blocks while shoveling out the groove, and then can crush the large blocks of soil into small blocks, so as to cover the groove after sowing.

[0004] However, when the device is actually used, if there is a depression or protrusion on the ground, the high flower wheel will not contact the ground, so the high flower wheel will not rotate, which affects the normal operation of the device and makes the device unsuitable for different ground surfaces. The applicability of the device is relatively poor. Utility Model Content

[0005] The main purpose of the utility model is to provide a sowing device for wheat planting, which can effectively solve the problem of relatively poor applicability of the device.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A sowing device for wheat planting comprises a mounting frame, wherein two support frames are fixed to the upper end of the mounting frame, a storage barrel is fixed between the two support frames, a stirring roller is rotatably mounted in the inner cavity of the storage barrel, a plurality of extension tubes communicating with the interior of the storage barrel are fixed to the lower end of the storage barrel, a furrowing plow is fixed to the lower end of the extension tube, a driving assembly is symmetrically fixed to the front end of the mounting frame, and a transmission assembly is also arranged at the upper end of the mounting frame.

[0008] Preferably, the driving assembly includes a first bracket fixed to the front end of the mounting frame. A sliding rod that penetrates upward is slidably installed at the lower end of the first bracket. A first limit block is fixed to the upper end of the sliding rod. A limit rod that is slidably connected to the first bracket is also fixed to the lower end of the first limit block. A second limit block is jointly fixed to the lower ends of the first limit block and the limit rod. A return spring sleeved on the outer surface of the sliding rod is jointly fixed between the second limit block and the first limit block. A high-profile wheel is rotatably installed at the lower end of the second limit block. A first pulley is rotatably installed at the right end of the first limit block. A second pulley is also fixed to one end of the high-profile wheel.

[0009] Preferably, the transmission assembly includes two second brackets fixed to the upper end of the mounting frame. A rotating rod is rotatably installed between the two second brackets. One-way bearings are arranged at both the left and right ends of the rotating rod. A third pulley is fixed to the end of the one-way bearing that is not connected to the rotating rod. A transmission belt is jointly wound between the third pulley, the first pulley, and the second pulley. The rotating rod and the stirring roller are also connected by a transmission belt.

[0010] Preferably, when the device moves forward, the high-profile wheel can drive the rotating rod to rotate;

[0011] When the device moves backward, the high-profile wheel cannot drive the rotating rod to rotate.

[0012] Preferably, a plurality of sealing plates are further fixed to the outer surface of the stirring roller.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. The seeding device adopts the design of the driving assembly. By the mutual cooperation between the return spring and the high-profile wheel, when the device moves forward, the high-profile wheel can always be in contact with the ground, preventing seeding from being unable to continue when there are depressions or protrusions on the ground. At the same time, due to the design of two sets of driving assemblies, a dual guarantee effect can be achieved, enabling the device to be applicable to different lands during use and being more stable.

[0015] 2. The seeding device adopts the design of the sealing plates, enabling the sealing plates to intermittently seal the extension pipe during use, further enabling the device to seed at a fixed distance and in a fixed quantity, increasing the applicability of the device during use.

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figure 1 shown, a seeding device for wheat planting includes an installation frame 1. Two support frames 11 are fixedly arranged at the upper end of the installation frame 1. A storage barrel 12 for storing seeds is fixedly arranged between the two support frames 11. When the device is in use, the seeds mixed with stirring agents are poured into the storage barrel 12. A stirring roller 13 for stirring the seeds is rotatably installed in the inner cavity of the storage barrel 12, which can stir the seeds in the storage barrel 12, prevent the damp and caked seeds from blocking the discharge port, thus affecting the normal operation of the device, and at the same time prevent the seeds from accumulating on the side wall of the storage barrel 12, so that the seeds can continuously come out from the extension pipe 14, thereby achieving the purpose of seeding.

[0022] In addition, a plurality of extension pipes 14 communicated with the inside of the storage barrel 12 are fixedly arranged at the lower end of the storage barrel 12. A furrow opener 15 is fixedly arranged at the lower end of the extension pipe 14. When the device is in use, the furrow opener 15 can open furrows in the land, so that the device can sow seeds. Two driving assemblies 2 are symmetrically fixedly arranged at the front end of the installation frame 1. A transmission assembly 3 is also arranged at the upper end of the installation frame 1. A plurality of sealing plates 16 for sealing the extension pipes 14 are fixedly arranged on the outer surface of the stirring roller 13. When the sealing plates 16 seal the extension pipes 14, the wheat seeds will not come out from the extension pipes 14. When the sealing plates 16 do not seal the extension pipes 14, the wheat seeds will come out from the extension pipes 14, so that the device can sow seeds at a fixed distance and in a fixed quantity during use. When it is not necessary to sow seeds at a fixed distance and in a fixed quantity, only the sealing plates 16 need to be removed, which increases the applicability of the device.

[0023] As Figure 2As shown, the driving assembly 2 includes a first bracket 21 fixed to the front end of the mounting frame 1. A sliding rod 22 that penetrates upward is slidably installed at the lower end of the first bracket 21, enabling the sliding rod 22 to slide upward or downward. A first limit block 23 is fixed to the upper end of the sliding rod 22. A limit rod 24 that is slidably connected to the first bracket 21 is also fixed to the lower end of the first limit block 23. The first limit block 23 and the limit rod 24 are used to limit the sliding rod 22 to prevent the sliding rod 22 from rotating when moving upward or downward, thus affecting the normal operation of the device. A second limit block 25 is jointly fixed to the lower ends of the first limit block 23 and the limit rod 24.

[0024] In addition, a return spring 26 sleeved on the outer surface of the sliding rod 22 is jointly fixed between the second limit block 25 and the first limit block 23. A high-flange wheel 27 is rotatably installed at the lower end of the second limit block 25. Due to the design of the return spring 26, the high-flange wheel 27 can always be in contact with the ground during the use of the device, enabling the device to be applicable to uneven ground. When the high-flange wheel 27 is in contact with the ground and the device moves forward, the high-flange wheel 27 can be driven to rotate. A first pulley 28 is rotatably installed at the right end of the first limit block 23. A second pulley 29 is also fixed to one end of the high-flange wheel 27.

[0025] As Figure 1 and Figure 3 As shown, the transmission assembly 3 includes two second brackets 31 fixed to the upper end of the mounting frame 1. A rotating rod 32 is jointly rotatably installed between the two second brackets 31. Among them, the two second brackets 31 are used to support the rotating rod 32. One-way bearings 33 are provided at both the left and right ends of the rotating rod 32. The one-way bearings 33 are prior art. A third pulley 34 is fixed to the end of the one-way bearing 33 that is not connected to the rotating rod 32. A transmission belt is jointly wound between the third pulley 34, the first pulley 28, and the second pulley 29, enabling the third pulley 34 to be driven to rotate when the high-flange wheel 27 rotates. Among them, the first pulley 28 can move upward or downward following the first limit block 23. Since the high-flange wheel 27 can move upward or downward when rotating, the first pulley 28 can act as a tension pulley, enabling the high-flange wheel 27 to drive the third pulley 34 to rotate when rotating. The rotating rod 32 is also connected to the stirring roller 13 through a transmission belt, enabling the stirring roller 13 to be driven to rotate when the rotating rod 32 rotates.

[0026] Due to the characteristic that the one-way bearing 33 can only rotate in one direction, when the device moves forward, the third pulley 34 can drive the rotating rod 32 to rotate. At the same time, due to the design of the two high-flange wheels 27, a double insurance effect can be achieved. When the device moves forward and one of the high-flange wheels 27 does not contact the ground, the rotating rod 32 can always rotate, increasing the stability of the device during use. At the same time, when the device moves backward, the high-flange wheel 27 cannot drive the rotating rod 32 to rotate, thus preventing the device from continuing to sow seeds and affecting the normal sowing work of the device.

[0027] The specific implementation of this embodiment is as follows: When the device is in use, the installation frame 1 is connected to the tractor so that the tractor can drive the device to move forward. Then, the seeds are poured into the storage barrel 12. When the high-flange wheel 27 contacts the ground and the device moves forward, the high-flange wheel 27 can drive the rotating rod 32 to rotate. Then, the rotating rod 32 drives the stirring roller 13 to stir the seeds in the storage barrel 12 through a belt, so that the seeds can evenly come out of the extension pipe 14 and be planted in the ground.

[0028] Due to the design of the sealing plate 16, when the stirring roller 13 rotates, the sealing plate 16 can intermittently seal the extension pipe 14, so that the seeds come out of the extension pipe 14 intermittently. Thus, the device can sow seeds at a fixed distance and in a fixed quantity during use. When it is not necessary to sow seeds at a fixed distance and in a fixed quantity, only the sealing plate 16 needs to be removed. If the device does not need to sow seeds during the forward movement, only the sealing plate 16 needs to be used to seal the extension pipe 14, increasing the applicability of the device.

[0029] It should be noted that the specific installation methods, circuit connection methods, and control methods of the stirring roller 13, high-flange wheel 27, one-way bearing 33, etc. in the present invention are all conventional designs, and the present invention will not elaborate in detail.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
