Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a greenhouse rice-pulling machine. Background Technology

[0002] The development trend of modern agricultural greenhouses is inevitably towards large-scale, mechanized, and intelligent operations, fundamentally solving the problems of the backwardness and inefficiency of the traditional model that relies solely on manual labor.

[0003] Especially every summer, an increasing number of large-scale greenhouse projects, including glass greenhouses and plastic greenhouses, require clearing and hauling seedlings to prepare for the next season's planting. However, this necessitates a significant investment of manpower and time each year to handle the massive quantities of seedlings – a process known as seedling hauling. Besides the high labor intensity and poor working conditions, the large volume of the gathered stems requires considerable storage space, making subsequent processing even more difficult. Current methods mostly involve open-air piling, natural drying, or composting, which not only takes a long time to process but also causes severe environmental pollution. This traditional method of seedling hauling also faces numerous challenges, including difficulty in finding workers, high costs, time-consuming and labor-intensive hauling, cumbersome seedling transportation, and a lack of suitable storage locations, causing immense headaches for countless greenhouse operators. A few greenhouse production bases in China have begun to try using imported rice stalk pulling machines. However, the high price of these machines, along with the high purchase and maintenance costs, deters growers. Furthermore, the rice stalk pulling machines currently on the market are all quite similar in their feeding methods, using a conveyor belt to pull the stems into the crushing chamber. To protect the high-speed rotating crushing blades, metal detectors are usually installed at the feeding position to prevent metal materials from entering the crushing chamber and damaging the blades. However, these metal detectors are mostly installed above the conveyor belt in a fixed position. When conveying different stems, the actual height of the conveyor belt varies greatly depending on the thickness of the stem stack and the moisture content of the stems. Metal detectors with a fixed height are prone to missing detections, resulting in a high damage rate to the crushing blades. They also lack adjustable metal detection functionality.

[0004] Now, a new type of greenhouse rice-pulling machine is proposed to solve the above problems. Summary of the Invention

[0008] Preferably, the first positioning bolt passes through the top of the guide roller mounting bracket and extends into the interior of the first positioning screw hole, and the positions and dimensions of the first positioning bolt and the first positioning screw hole correspond one-to-one.

[0009] Preferably, the external shape and dimensions of the detector mounting bracket are adapted to the internal shape and dimensions of the inclined groove, and the detector mounting bracket can slide up and down along the inside of the inclined groove.

[0010] Preferably, the second positioning bolt passes through the detector mounting bracket and extends into the interior of the second positioning screw hole, which is arranged at equal intervals.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the greenhouse rice seedling puller not only realizes the adjustable metal detection function and the double-layer slow crushing function, but also realizes the function of easy entry into small-sized greenhouses;

[0018] (1) The device is equipped with an inclined groove, a guide roller mounting frame, a recycling cloth guide roller, a first positioning bolt, a first positioning screw eye, a stalk recycling cloth, a second positioning screw eye, a detector mounting frame, a second positioning bolt, a metal detector, a concave frame, a recycling cloth roll roller, a first reduction motor, and a feeding guide plate. In use, the stalk recycling cloth wound on the recycling cloth roll roller is pulled upwards, passing through the detector mounting frame and the recycling cloth guide roller along the inclined groove, and then continuously pulled outwards and laid flat on the ground. The stalks are stacked on the recycling cloth roll roller. As the first reduction motor on the concave frame starts, it drives the recycling cloth roll roller to rotate continuously. The recycling cloth roll roller continuously retracts the stalk recycling cloth, and the crop stalks on the stalk recycling cloth are continuously brought to the top of the feeding hopper and fall into the crushing hopper along the feeding guide plate. During the stalk recycling process, the metal detector is positioned... Below the stem, depending on the type of stem being processed, the height of the stem recycling cloth can be adjusted to control the position of the recycling cloth guide roller and the detector mounting bracket. When the stem is long, the recycling cloth guide roller is moved forward; when the stem is short, it is moved backward to facilitate the stem entering the crushing chamber. The first positioning bolt and the first positioning screw hole facilitate the adjustment of the position of the guide roller mounting bracket on both sides of the recycling cloth guide roller. As the position of the recycling cloth guide roller is adjusted and the moisture content of the stem varies, the height of the stem recycling cloth will also differ. Based on the height of the stem recycling cloth, the installation position of the detector mounting bracket can be adjusted. The second positioning bolt and the second positioning screw hole on both sides of the detector mounting bracket are adapted to the metal detector that matches the height of the stem recycling cloth. The metal detector detects from bottom to top, making the detection more accurate and less prone to missed detection, thus realizing the adjustable function of metal detection.

[0019] (2) By setting up a crushing bin, a fixed blade group, a moving blade roller, a first gear, a second reduction motor, a second gear, a receiving hopper, a conveyor belt support frame, a drive motor, a scraper conveyor belt, a tipping bucket, and a trolley base, when in use, the crop stalks conveyed by the stalk recycling cloth enter the crushing bin along the feed guide plate. The second reduction motor drives the moving blade roller to rotate continuously through the second gear. There are two sets of moving blade rollers on the upper and lower sides. The moving blade roller and the fixed blade group work together to cut the stalks at a uniform speed. The moving blade roller and the fixed blade group of the upper layer squeeze and crush, reducing the volume of the stalks. The lower layer further crushes and cuts tough objects. The stalk material after being cut and crushed falls into the receiving hopper. The drive motor on the conveyor belt support frame drives the scraper conveyor belt to rotate continuously, guiding the crushed stalks to the tipping bucket. The tipping bucket receives the crushed material. The universal wheels at the bottom of the trolley base facilitate the displacement of the tipping bucket and quickly discharge the material, realizing the function of double-layer slow crushing.

[0020] (3) By setting up a steering wheel mounting plate, a drive wheel mounting frame, a third geared motor, a main drive wheel, a gear ring, a servo motor and a fourth gear, when in use, the fixed wheel at the bottom of the main frame cooperates with the main drive wheel, and the third geared motor on the drive wheel mounting frame drives the main drive wheel to rotate continuously, so that the equipment can be displaced. When turning is required, the servo motor is controlled by the remote control to run, and the servo motor drives the gear ring to rotate through the fourth gear. The drive wheel mounting frame rotates synchronously, and the direction of the main drive wheel changes, so that a small radius turn can be achieved, and it can quickly enter the small-sized greenhouse. The operation is more convenient, and the function of easy access to the small-sized greenhouse is realized. Attached Figure Description

An inclined groove 4 is provided inside the front end of the feeding bin 3. Multiple sets of second positioning screw holes 10 are respectively provided on the left and right sides of the front end of the feeding bin 3. The inclined groove 4 is horizontally... A detector mounting frame 11 is provided. Two sets of second positioning bolts 12 are inserted into the left and right sides of the front end of the detector mounting frame 11 respectively. A metal detector 13 is installed at the middle position of the front end of the detector mounting frame 11. A concave frame 14 is fixedly connected to the bottom of the front end of the feed bin 3. A recycling cloth roll roller 15 is laterally movably connected between the left and right sides inside the concave frame 14. A first reduction motor 16 is installed on the right side of the concave frame 14. Two sets of feed guide plates 17 are obliquely welded between the left and right sides inside the feed bin 3. The outside of the recycling cloth roll roller 15 is wrapped with stalk recycling cloth 9.

[0033] The first positioning bolt 7 passes through the top of the guide roller mounting frame 5 and extends into the interior of the first positioning screw eye 8. The positions and dimensions of the first positioning bolt 7 and the first positioning screw eye 8 correspond one-to-one. The external shape and dimensions of the detector mounting frame 11 are adapted to the internal shape and dimensions of the inclined groove 4. The detector mounting frame 11 can slide up and down along the interior of the inclined groove 4. The second positioning bolt 12 passes through the detector mounting frame 11 and extends into the interior of the second positioning screw eye 10. The second positioning screw eyes 10 are arranged at equal intervals. The stalk recycling cloth 9 passes through the rear of the recycling cloth guide roller 6 and the detector mounting frame 11 and is wound around the outside of the recycling cloth roll roller 15. The output end of the first reduction motor 16 is fixedly connected to the left side of the recycling cloth roll roller 15. The bottom end of the feeding guide plate 17 is connected to the top of the crushing chamber 18. The feeding guide plate 17 is symmetrically distributed about the vertical center line of the crushing chamber 18, which facilitates flexible adjustment of the detection position according to the different stalks during feeding and avoids missed detection.

[0034] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the metal detector 13 is located below the stem. Depending on the type of stem being processed and the height of the stem recycling cloth 9 hanging down, the positions of the recycling cloth guide roller 6 and the detector mounting bracket 11 can be adjusted. When the stem is long, the recycling cloth guide roller 6 is moved forward; when the stem is short, the recycling cloth guide roller 6 is moved backward to facilitate the stem entering the crushing chamber 18. The first positioning bolt 7 and the first positioning screw eye 8 facilitate the adjustment of the position of the guide roller mounting bracket 5 on both sides of the recycling cloth guide roller 6. As the position of the recycling cloth guide roller 6 is adjusted and the moisture content of the stem varies, the height of the stem recycling cloth 9 hanging down will also be different. Based on the height of the stem recycling cloth 9 hanging down, the installation position of the detector mounting bracket 11 can be adjusted. The second positioning bolt 12 and the second positioning screw eye 10 on both sides of the detector mounting bracket 11 are adapted to the metal detector 13, which is height-matched to the stem recycling cloth 9. The detection is performed from bottom to top, making the detection more accurate and less prone to missed detection.

A tipping bucket 28 is hinged to the top of the trolley base 29. Universal wheels 30 are movably connected to the four corners at the bottom of the trolley base 29. The toothed blocks on the outside of the fixed blade assembly 19 and the toothed grooves on the surface of the moving blade roller 20 are matched. The first gear 21 and the second gear 23 mesh with each other. The crushing chamber 18 and the receiving hopper 24 are internally connected. The output end of the drive motor 26 is connected to the scraper conveyor belt 27 through a pulley. The slow crushing effect is good, and it is convenient for discharge and conveying.

[0036] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the second reduction motor 22 drives the moving cutter roller 20 to rotate continuously through the second gear 23. There are two sets of moving cutter rollers 20 on the upper and lower sides. The moving cutter rollers 20 and the fixed cutter group 19 work together to cut the stems at a uniform speed. The upper moving cutter rollers 20 and the fixed cutter group 19 squeeze and crush the stems, reducing their volume. The lower layer further crushes and cuts tough materials. The crushed stems fall into the receiving hopper 24. The drive motor 26 on the conveyor belt support frame 25 drives the scraper conveyor belt 27 to rotate continuously, guiding the crushed stems to the tipping bucket 28. The tipping bucket 28 receives the crushed material. The universal wheels 30 at the bottom of the trolley base 29 facilitate the movement of the tipping bucket 28 for rapid material discharge.

[0037] Example 3: Two sets of steering wheel mounting plates 32 are fixedly connected to the left side of the bottom of the main frame 1. A drive wheel mounting bracket 33 is movably connected to the left side of the bottom of the steering wheel mounting plate 32. A main drive wheel 35 is movably connected between the front and rear ends inside the drive wheel mounting bracket 33. A third reduction motor 34 is installed at the outward end of the drive wheel mounting bracket 33. A gear ring 36 is sleeved on the top of the drive wheel mounting bracket 33.

The gear ring 36 and the fourth gear 38 mesh, which can achieve small-radius turning and facilitate entry into small-sized greenhouses.

[0038] Specifically, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the third reduction motor 34 on the drive wheel mounting frame 33 drives the main drive wheel 35 to rotate continuously, allowing the equipment to move. When turning is required, the servo motor 37 is controlled by the remote control 39. The servo motor 37 drives the gear ring 36 to rotate through the fourth gear 38, and the drive wheel mounting frame 33 rotates synchronously. The direction of the main drive wheel 35 changes, enabling small-radius turns and quick entry into small greenhouses, making operation more convenient.

[0039] Working Principle: In use, the stalk recycling cloth 9 wound on the recycling cloth roll 15 is first pulled upwards, passing through the detector mounting frame 11 and the recycling cloth guide roller 6 along the inclined groove 4, and then continuously pulled outwards and laid flat on the ground. The stalks are stacked on the recycling cloth roll 15. As the first reduction motor 16 on the concave frame 14 starts, the first reduction motor 16 drives the recycling cloth roll 15 to rotate continuously. The recycling cloth roll 15 continuously retracts the stalk recycling cloth 9, and the crop stalks on the stalk recycling cloth 9 are continuously brought to the top of the feeding bin 3 and fall into the crushing bin 18 along the feeding guide plate 17. During the stalk recycling process, the metal detector 13 is located below the stalks. The height of the stalk recycling cloth 9 can be adjusted according to the type of stalks being processed. The positions of the cloth guide roller 6 and the detector mounting bracket 11 are adjusted according to the stem length. When the stem length is long, the cloth guide roller 6 is moved forward; when the stem length is short, the cloth guide roller 6 is moved backward to facilitate the stem entering the crushing chamber 18. The first positioning bolt 7 and the first positioning screw hole 8 facilitate the adjustment of the position of the guide roller mounting bracket 5 on both sides of the cloth guide roller 6. As the position of the cloth guide roller 6 is adjusted and the moisture content of the stem varies, the height of the drooping cloth 9 will also be different. According to the height of the drooping cloth 9, the installation position of the detector mounting bracket 11 can be adjusted. The second positioning bolt 12 and the second positioning screw hole 10 on both sides of the detector mounting bracket 11 are adapted to the metal detector 13, which is height-matched to the drooping cloth 9. The detection is performed from bottom to top, making the detection more accurate and less prone to missed detection. The crop stalks conveyed by the stalk recycling cloth 9 enter the crushing chamber 18 along the feed guide plate 17. The second reduction motor 22 drives the moving cutter roller 20 to rotate continuously through the second gear 23. There are two sets of moving cutter rollers 20 at the top and two sets at the bottom. The moving cutter rollers 20 and the fixed cutter group 19 work together to cut the stalks at a uniform speed. The upper moving cutter rollers 20 and the fixed cutter group 19 squeeze and crush, reducing the volume of the stalks. The lower layer further crushes and cuts tough objects. The shredded stalks fall into the receiving hopper 24. The drive motor 26 on the conveyor belt support frame 25 drives the scraper conveyor belt 27 to rotate continuously, guiding the crushed stalks to the tipping bucket 28. The tipping bucket 28 receives the crushed material. The universal wheels 30 at the bottom of the trolley base 29 facilitate the movement of the tipping bucket 28 for rapid material discharge. The fixed wheel 31 at the bottom of the main frame 1 cooperates with the main drive wheel 35. The third reduction motor 34 on the drive wheel mounting frame 33 drives the main drive wheel 35 to rotate continuously, allowing the equipment to move. When turning is required, the servo motor 37 is controlled by the remote control 39. The servo motor 37 drives the gear ring 36 to rotate through the fourth gear 38, and the drive wheel mounting frame 33 rotates synchronously. The direction of the main drive wheel 35 changes, enabling small-radius turns and quick entry into small greenhouses, making operation more convenient.
