Description

Technical Field

[0001] This invention relates to the field of trenching and drilling machines, specifically to a sweet potato curved cutting trenching and drilling machine. Background Technology

[0002] As is well known, sweet potatoes are mostly cultivated by first ridging and then planting cuttings in furrows. Therefore, to facilitate the treatment of planting soil during the sweet potato planting process, we propose a sweet potato curved cutting furrowing and hole-drilling machine.

[0003] A search revealed that Chinese patent CN210491623U, published on May 12, 2020, discloses a sweet potato cutting trenching and drilling machine. The general description includes a frame, which is fixedly connected to an upper drive shaft via left and right bearing seats. A drive wheel is fixed to each end of the drive shaft. A drive sprocket is fixed on the drive shaft, and the drive sprocket is connected to a driven sprocket via a chain. The driven sprocket is fixed to a crankshaft, and both ends of the crankshaft are connected to the frame via bearing seats. The crankshaft is connected to one or more crank-connecting rod mechanisms. The connecting rod of the crank-connecting rod mechanism moves vertically within a vertical guide sleeve, which is directly below the crankshaft and fixed to the frame. A trencher is located on the frame in front of the crankshaft. As the drive wheels rotate, the connecting rod moves vertically to complete the trenching and drilling operation for sweet potato vines in the trenches created by the trencher. In use, trenching and drilling can be completed simultaneously.

[0004] Although the aforementioned existing technical solutions can achieve simultaneous trenching and hole drilling, the hole drilling operation involves inserting a connecting rod directly into the soil, and then pulling it out relative to the soil after insertion. During this process, the frame is still moving, so the connecting rod will also be in a horizontal state relative to the soil. This inevitably causes damage to the hole formed by the direct insertion, resulting in poor practicality. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a sweet potato cutting trenching and drilling machine. During the drilling process, the first and second drilling frames can remain relatively stationary relative to the soil in a horizontal position, while only vertical drilling and feeding operations are performed. This further ensures the drilling effect. Furthermore, the drilling spacing and number of holes can be adjusted, and the adjustment is relatively simple, making it highly operable and practical.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example

[0033] Please see the appendix Figure 1 -Appendix Figure 9A sweet potato cutting trenching and drilling machine includes a frame 1, characterized by further including a transmission chain belt 2 and multiple mounting frames 3. Two front wheel frames 4 and two rear wheel frames 5 are fixedly connected to the frame 1. The two front wheel frames 4 and the two rear wheel frames 5 are arranged symmetrically front and rear. Each of the two front wheel frames 4 is rotatably connected to a front synchronous pulley 6, and each of the two rear wheel frames 5 is rotatably connected to a rear synchronous pulley 7. The transmission chain belt 2 is driven by the two front synchronous pulleys 6 and the two rear synchronous pulleys 7. Through the cooperation of the frame 1, the front synchronous pulleys 6, the rear synchronous pulleys 7, and the transmission chain belt 2, multiple mounting frames 3 are installed, facilitating the synchronous installation of multiple first and second drilling frames, thereby forming holes during the drilling operation. The first and second drilling frames can remain relatively stationary relative to the soil in a horizontal position, performing only vertical drilling and feeding operations, thus further ensuring the drilling effect. Multiple mounting frames 3 are mounted on the drive chain belt 2, and the first and second drilling frames are slidably connected to each of the mounting frames 3. Each of the first drilling frames is connected to a first connecting spring 8, which is connected to each of the mounting frames 3. Similarly, each of the second drilling frames is connected to a second connecting spring 9, which is also connected to each of the mounting frames 3. The frame 1 has a central notch annular groove 10, and a bottom protrusion 11 is provided within the central notch annular groove 10. Through the coordination of the first connecting spring 8, the second connecting spring 9, and the bottom protrusion 11… The first and second hole-opening frames are designed to facilitate the pushing and retraction of the first and second hole-opening frames for hole opening and resetting after hole opening. When the first hole-opening frame moves below the bottom protrusion 11, the first connecting spring 8 is compressed, and the first hole-opening frame is pushed out relative to the mounting flat frame 3, forming a drilling operation. Similarly, when the second hole-opening frame moves below the bottom protrusion 11, the second connecting spring 9 is compressed, and the second hole-opening frame is pushed out relative to the mounting flat frame 3, forming a drilling operation. Both front wheel frames 4 are rotatably connected to front travel wheels 12, which are respectively connected to two front synchronous wheels 6. An external frame 13 connects the two front wheel frames 4, and a traction sleeve 29 is provided on the external frame 13 to facilitate traction relative to the external frame 13. A trencher 14 is installed inside the external frame 13. The two rear... A bogie is connected between the wheel frames 5. Two steering wheels 15 are mounted on the bogie. The bogie includes two rotating frames 16. A rotating shaft 17 is fixedly connected to each of the two rotating frames 16. The two rotating shafts 17 are rotatably connected to the two rear wheel frames 5 respectively. An installation shaft 18 is fixedly connected to each of the two rotating frames 16. The two steering wheels 15 are rotatably connected to the two installation shafts 18 respectively. An assembly shaft 19 is fixedly connected to each of the two rotating frames 16. A coordinating rod 20 is connected between the two assembly shafts 19 to facilitate the turning of the frame 1 during travel. Multiple protruding anti-slip ridges 21 are provided on the two front travel wheels 12 and the two steering wheels 15 to increase the friction coefficient of the front travel wheels 12 and the steering wheels 15 relative to the ground during travel and reduce the occurrence of slippage.

[0034] It should be further explained that both the first and second opening frames include end frames 22, connecting frames 23, and pointed frames 24. Multiple end frames 22 are respectively connected to multiple first connecting springs 8 and multiple second connecting springs 9. Multiple connecting frames 23 are rotatably connected to multiple end frames 22, and multiple pointed frames 24 are rotatably connected to multiple end frames 22. Each connecting frame 23 is equipped with a connecting structure, which matches each of the multiple end frames 22 and the multiple pointed frames 24. Each connecting structure includes a limiting pin 25 and a limiting spring 26. Multiple limiting pins 25 are slidably connected to multiple connecting frames 23, and multiple limiting springs 26 are fixedly connected within multiple connecting frames 23. Connected to multiple limiting pins 25, the pointed frame 24 has a first limiting groove 27 that matches the limiting pin 25, and the end frame 22 has a second limiting groove 28 that matches the limiting pin 25. Through the design of the first and second opening frames, it is convenient to adjust relative to the mounting flat frame 3, so as to adjust the effectiveness of the insertion opening function of the multiple first and second opening frames. Moreover, the adjustment is relatively simple, the operability is good, and the practicality is good. The transmission chain belt 2 has multiple through holes 30, which are used for the passage of multiple pointed frames 24. The transmission chain belt 2 has multiple pairs of connecting holes, and each pair of connecting holes is provided with a pair of bolts 31. The multiple pair of bolts 31 are threadedly connected to the multiple mounting flat frames 3.

[0035] In summary, the working process of this sweet potato curved cutting trenching and drilling machine is as follows: First, the machine is transported to the desired location. Then, an external traction device, via the traction sleeve 29, provides overall traction to the external frame 13 and the machine frame 1. During traction, the forward travel wheel 12 and the steering wheel 15 roll relative to the ground, adjusting the position of the machine frame 1 relative to the planting ridge. The machine is then moved relative to the planting ridge, and during this movement, the trencher 14 performs trenching operations on the planting ridge. The forward travel wheel 12, moving relative to the ground, drives the front synchronous wheel 6 to rotate, thus driving the transmission chain belt 2. The movement of the transmission chain belt 2 achieves... The movement of multiple mounting frames 3 enables the movement of multiple first and second perforation frames. When the first and second perforation frames reach the bottom protrusion 11, they are pushed downwards and inserted into the planting ridge after trenching, thus completing the perforation operation. After the first and second perforation frames escape the position of the bottom protrusion 11, under the corresponding action of the first connecting spring 8 and the second connecting spring 9, the first and second perforation frames inserted into the soil are pulled out, completing the perforation operation. Furthermore, the first and second perforation frames can be adjusted by adjusting the insertion effect of the limiting pin 25 with the first limiting groove 27 and the second limiting groove 28, as shown in the attached diagram. Figure 4 As shown, the second hole-drilling frame near the front is in a hole-drilling operation state relative to the soil, at which time the corresponding limiting pin 25 is inserted into the corresponding first limiting groove 27. The second hole-drilling frame near the rear is in a hole-drilling operation state relative to the soil, at which time the corresponding limiting pin 25 is inserted into the corresponding second limiting groove 28. By adjusting the state of the first and second hole-drilling frames, the hole spacing and hole position can be adjusted, and the sweet potato cutting trenching and drilling machine can also be easily moved when not in use.
