Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and in particular to an automatic obstacle avoidance and ridging device for tobacco fields. Background Technology

[0002] Before transplanting tobacco plants, ridging is necessary. This ensures ample space for root growth and, mechanical ridging breaks up the compacted plow pan, increasing the soil-air contact area and providing a loose, well-aerated environment for the roots. Furthermore, furrow drainage reduces the risk of soil-borne diseases like black shank, and the ridges isolate the soil from the base of the tobacco stems, lowering the probability of pathogen transmission. It also facilitates later cultivation and hilling. However, existing ridging devices are fixed to the rear of agricultural machinery. During ridging, unforeseen underground obstacles can easily damage the plowshare and other components, or even cause the obstacles to become stuck inside the device, affecting the quality of the ridged soil. Summary of the Invention

The surface of the pull rod is provided with two second springs. The opposite ends of the two second springs are provided with sliding rings. The sliding rings are slidably connected to the surface of the pull rod.

[0005] In one embodiment, the obstacle avoidance mechanism further includes multiple cylinders disposed at the bottom end of the strip plate. A connecting pipe is provided between the cylinder and the corresponding telescopic sleeve. A piston rod is disposed inside the cylinder, with one end of the piston rod extending through the cylinder. A connecting plate is provided at the bottom end of the multiple piston rods. The top end of the connecting plate extends through the strip plate. An electric push rod is fixedly installed at the top end of the connecting plate. The telescopic end of the electric push rod is connected to the connecting plate. A third spring is provided at one end of the telescopic sleeve, and a pressure sensor is provided at the end of the third spring away from the inner wall of the telescopic sleeve.

[0006] In one embodiment, an exhaust pipe is provided on the lower surface of the connecting pipe, and a disassembly cover is threaded to the end of the exhaust pipe away from the connecting pipe, and a filter cloth is provided inside the disassembly cover.

[0007] In one embodiment, a mounting plate is connected between the strip plate and the frame. The bottom end of the mounting plate is provided with several U-shaped frames. The U-shaped frames are sleeved on the main mounting frame. Fixing bolts are provided on the U-shaped frames. Washers are provided at the gap between the nuts of the fixing bolts and the U-shaped frames.

[0008] In one embodiment, the rotary tillage mechanism includes an equipment box mounted on a main mounting frame and a rotary tillage rod rotatably mounted at the bottom of the main mounting frame. The rotary tillage rod passes through the equipment box, and a transmission rod is rotatably connected inside the equipment box. A power rod is mounted on the equipment box. A large conical gear is provided at one end of the power rod and at the middle of the surface of the rotary tillage rod. Small conical gears that mesh with the large conical gear are provided at both ends of the power rod. Multiple rotary tillage blades are provided on the surface of the rotary tillage rod.

[0009] In one embodiment, a connecting hoop is provided at the top of the main plow body, the main plow body and the frame body are connected by the connecting hoop, and a reinforcing rod is provided between the main plow body and the sub-plows.

[0010] In one embodiment, a forming scraper is provided on the side of the frame away from the main mounting frame, and a flat plate is hinged to the end of the forming scraper away from the frame. A plurality of counterweights are provided on one side of the flat plate.

[0014] The aforementioned obstacle avoidance mechanism, through three sets of telescopic rods, telescopic sleeves, a first spring, two sets of pulling rods, a second spring, and a sliding ring, allows the ridging device to automatically move backward and rise under the resistance of large obstacles during ridging operations. This rotation and lifting prevents damage to related components from the obstacles. After passing the obstacle, multiple springs work together to press the device back into place, allowing it to continue ridging operations. Simultaneously, when the frame is raised to a large extent, the telescopic rods compress the pressure sensors, activating the electric push rods. These electric push rods then drive multiple piston rods to extract gas from the telescopic sleeves, thus accelerating the telescopic rods and increasing the range of rotation and lifting of the frame. This process removes larger obstacles, preventing them from remaining inside the device and ensuring the quality of the tobacco field ridges. The aforementioned U-shaped frame and fixing bolts make the modular design of the obstacle avoidance mechanism and rotary tillage mechanism more convenient during equipment maintenance, and allow for faster disassembly of both. The aforementioned rotary tillage mechanism can utilize the power output of the tractor to complete the rotary tillage, achieving rotary tillage and pulverization during the traction process. When used in conjunction with the main plow and the secondary plow, it results in better ridge formation in tobacco fields and improved soil aeration. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

[0019] The following is combined with Figures 1-9 The present invention describes an automatic obstacle avoidance and ridging device for tobacco fields.

[0020] In one embodiment, an automatic obstacle avoidance and ridging device for tobacco fields includes: a main mounting frame 100 and a frame body 300. The frame body 300 is provided with several evenly distributed main plow bodies 400 at one end away from the main mounting frame 100, and the opposite sides of two adjacent main plow bodies 400 are provided with branch plows 500. Rotary tillage mechanism 200, which is used to rotary tillage and crush the soil in the tobacco field, is mounted on the main mounting frame 100. The obstacle avoidance mechanism 600 includes a strip plate 610 fixedly installed on the top of the frame 300. Multiple connecting seats 620 are hinged on the strip plate 610. A telescopic sleeve 621 is provided at the end of the connecting seat 620 away from the strip plate 610. A telescopic rod 622 is hinged to the top of the frame 300. The telescopic rod 622 and the telescopic sleeve 621 are slidably connected. The end of the telescopic sleeve 621 away from the telescopic rod 622 is hinged to the strip plate 610. A first spring 623 is provided between the connecting seat 622 and the telescopic rod 622. The top of the strip plate 610 is provided with two fixing frames 630. The top of the frame body 300 is hinged with a pull rod 631 corresponding to the fixing frame 630. The surface of the pull rod 631 is provided with two second springs 632. The opposite ends of the two second springs 632 are provided with sliding rings 633. The sliding rings 633 are slidably connected to the surface of the pull rod 631. The fixing frame 630 is slidably connected to the pull rod 631, and the two sliding rings 633 are located on both sides of the fixing frame 630.

[0021] It should be noted that this ridging device is matched with a 55-75KW tractor. It is connected to the tractor through the front suspension of the main mounting frame 100 of the ridging device. The tractor's power is connected to the power rod 211 through the drive shaft, which drives the rotary tiller to till the soil. It should be noted that when the ridging device encounters unforeseen obstacles underground, the bottom of the rotary tillage mechanism 200 is higher than the main plow body 400, thus providing effective protection for the rotary tillage mechanism 200. It should be noted that the structural components in the rotary tillage mechanism 200 are all common components in agricultural machinery and equipment. Therefore, no detailed description is given for components such as the rotary tillage blade 214 and the rotary tillage rod 213. Instead, the two are combined to further improve the forming effect of the tobacco field ridges.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a connecting hoop 410 is provided at the top of the main plow body 400, and the main plow body 400 and the frame body 300 are connected by the connecting hoop 410. A reinforcing rod is provided between the main plow body 400 and the sub-plows 500. The reinforcing rod can increase the stability of the sub-plows 500, and at the same time increase the overall connection between the main plow body 400 and the sub-plows 500.

[0023] A forming scraper 330 is provided on the side of the frame 300 away from the main mounting frame 100. A flattening plate 340 is hinged to the end of the forming scraper 330 away from the frame 300. Multiple counterweights 350 are provided on one side of the flattening plate 340. During the operation of the device, the gradually shrinking forming scraper 330 cooperates with the main plow body 400 and the sub-plow 500 to achieve the final forming of the ridge, resulting in a better ridge forming effect. At the same time, the hinged flattening plate 340 can perform scraping operations on the top of the ridge, and the counterweights 350 can improve the flattening effect of the flattening plate 340. Both sides of the bottom end of the frame 300 are provided with side plates 310 that cooperate with the corresponding main plow body 400, and both sides of the bottom end of the frame 300 are provided with guide plates 320 that cooperate with the side plates 310. The side plates 310 and guide plates 320 can be used with the main plow bodies 400 and the branch plows 500 on both sides to better achieve the ridging effect of the device.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the obstacle avoidance mechanism 600 also includes multiple cylinders 640 disposed at the bottom of the strip plate 610. A connecting pipe 642 is provided between the cylinder 640 and the corresponding telescopic sleeve 621. A piston rod 641 is disposed inside the cylinder 640. One end of the piston rod 641 extends through the cylinder 640. A connecting plate 643 is provided at the bottom of the multiple piston rods 641. The top end of the connecting plate 643 extends through the strip plate 610. An electric push rod 644 is fixedly installed at the top end of the connecting plate 643. The telescopic end of the electric push rod 644 is connected to the connecting plate 643. A third spring 650 is provided at one end of the telescopic sleeve 621. A pressure sensor 651 is provided at the end of the third spring 650 away from the inner wall of the telescopic sleeve 621.

[0025] An exhaust pipe 652 is provided on the lower surface of the connecting pipe 642. A disassembly cover 653 is threadedly connected to the end of the exhaust pipe 652 away from the connecting pipe 642, and a filter cloth is provided inside the disassembly cover 653. The exhaust pipe 652 is provided to avoid rigid pulling, so that the piston rod 641 will not get stuck when it is pulled. At the same time, the incoming and outgoing gas will pass through the filter cloth, which can prevent impurities from entering the components and facilitate the resetting operation of the device.

[0026] In this embodiment, when the telescopic rod 622 moves continuously within the telescopic sleeve 621, it will touch the pressure sensor 651 after reaching a certain position. The third spring 650 can bend to prevent damage to the pressure sensor 651 during rigid compression. The pressure sensor 651 sends a signal to activate the electric push rod 644. The electric push rod 644 will drive multiple piston rods 641 to operate, and the gas inside the telescopic sleeve 621 will be quickly extracted, thereby driving the continuous movement of the telescopic rod 622, thereby increasing the rotation and lifting range of the frame 300 and achieving rapid obstacle crossing.

[0027] It should be noted that during the gas transmission process inside the telescopic sleeve 621, the exhaust pipe 652 may leak. However, due to the amplitude of the air extraction and the pushing of the telescopic rod 622, the piston rod 641 can still pull the telescopic rod 622. This is a quick operation. During this period, the exhaust volume of the exhaust pipe 652 is limited and will not affect the normal operation of the device.

[0028] It should be noted that the pressure sensor 651 activates the electric push rod 644 after receiving the signal. This is a relatively common technology and therefore has not been described in detail. You can choose the built-in processing chip or set up a separate PLC controller.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a mounting plate 370 is provided between the strip plate 610 and the frame 300. Several U-shaped frames 380 are provided at the bottom of the mounting plate 370. The U-shaped frames 380 are sleeved on the main mounting frame 100. Fixing bolts 381 are provided on the U-shaped frames 380. Washers 382 are provided in the gap between the nut of the fixing bolts 381 and the U-shaped frames 380.

[0030] Both the main mounting frame 100 and the frame body 300 have access ports at their top ends, with multiple access ports matching the positions of the main plow body 400 and the U-shaped frame 380. The access ports facilitate the removal of the fixing bolts 381 and the subsequent maintenance of the device.

[0031] In this embodiment, the U-shaped frame 380 and fixing bolts 381 make the modular design of the obstacle avoidance mechanism 600 and the rotary tillage mechanism 200 more convenient during device maintenance, and allow for faster disassembly of both.

[0032] like Figure 1 , Figure 8 and Figure 9As shown, the rotary tillage mechanism 200 includes an equipment box 210 mounted on the main mounting frame 100 and a rotary tillage rod 213 rotatably mounted at the bottom of the main mounting frame 100. The rotary tillage rod 213 passes through the equipment box 210. A transmission rod 212 is rotatably connected inside the equipment box 210. A power rod 211 is mounted on the equipment box 210. A large bevel gear 215 is provided at one end of the power rod 211 and at the middle of the surface of the rotary tillage rod 213. Small bevel gears 216 that mesh with the large bevel gear 215 are provided at both ends of the power rod 211. A plurality of rotary tillage blades 214 are provided on the surface of the rotary tillage rod 213.

[0033] In this embodiment, the tractor transmits power to the power lever 211, which rotates, thereby driving the large bevel gear 215 above to rotate. Under the meshing action of multiple large bevel gears 215 and small bevel gears 216, the rotary tiller 213 rotates, thereby driving the rotary tiller blades 214 to rotate, realizing rotary tillage and pulverization of the soil in the tobacco field. Rotary tillage and pulverization are achieved during traction. When used in conjunction with the main plow body 400 and the secondary plow 500, the ridge formation effect in the tobacco field is better, and the soil permeability is better.

[0034] like Figure 1 and Figure 3 As shown, multiple hinges 360 are provided between the main mounting frame 100 and the frame body 300. When the frame body 300 is crossing an obstacle, it can rotate at a fixed point to increase the stability of the obstacle crossing, limit the range of the obstacle crossing, and is easy to disassemble, which also facilitates the separation and maintenance of the obstacle avoidance mechanism 600 and the main mounting frame 100 in the later stage.

[0035] Working principle: The device is installed on the tractor. As the tractor moves in the tobacco field, the rotary tillage mechanism 200 will first perform rotary tillage and pulverization of the soil in the tobacco field. With the cooperation of the main plow body 400 and the secondary plow 500, the ridging operation of the tobacco field is completed. When the ridging device encounters unforeseen obstacles underground, because the bottom of the rotary tillage mechanism 200 is higher than the main plow body 400, the obstacle will pass over the rotary tillage mechanism 200 and come into contact with the components on the frame 300. Under the action of resistance, the frame 300 automatically moves backward and rises, rotating and lifting, driving the telescopic rod 622 to move towards the telescopic sleeve 621. The first spring 623 bends, and at the same time, the frame 300 will also drive the pulling rod 631 to move. With the combination of the two sets of second springs 632 and sliding rings 633, the fixed frame 630 is lifted, completing the automatic obstacle avoidance operation of the device. After overcoming the obstacle, under the action of the first spring 623 and the second spring 632, the frame 300 will automatically reset and continue the ridging operation.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
