Description

Technical Field

[0001] This utility model relates to the field of agricultural planting machinery technology, specifically to an integrated sowing device. Background Technology

[0002] Morel mushrooms are a rare edible and medicinal fungus. Their caps are oval or conical with honeycomb-like pits on the surface, and their stems are cylindrical and hollow. They are named for their bumpy, stomach-like appearance, and are also known as morel mushrooms, honeycomb mushrooms, etc. Morel mushrooms are increasingly popular in the market due to their unique flavor and high nutritional value (rich in protein, various amino acids, vitamins, and minerals). To meet the continuously growing demand, morel mushroom cultivation is gradually shifting from scattered, manual methods to large-scale, intelligent operations. Chinese patent document CN212971002U discloses a morel mushroom sowing device. This device uses bearing seats and linkage rods to synchronize the rotation of two rotating wheels, ensuring normal rotation on slippery contact surfaces. The linkage rods and force rods control the sowing plate's movement simultaneously with the rotating wheels, thus improving the stability and efficiency of the sowing device and ensuring sowing on slippery contact surfaces. However, the sowing equipment cannot effectively adjust the amount of morel mushrooms sown, resulting in uneven sowing (i.e., too many morel mushrooms sown in some furrows and too few in others), which affects the growth of morel mushrooms and thus the fruiting rate. At the same time, the sowing equipment only sows in a single furrow direction, which is inefficient and requires multiple consecutive sowings, resulting in long time consumption and high cost. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide an integrated sowing device. This device can not only achieve uniform, precise, and smooth feeding of morel mushrooms, avoiding the problem of poor growth of morel mushrooms due to uneven sowing, but also sow multiple furrows at once, improving sowing efficiency and reducing sowing time.

[0004] The objective of this utility model is achieved through the following technical solution: An integrated seeding device includes a frame, a feeding mechanism, a furrow opener, a soil covering mechanism, and a walking mechanism. The frame adopts a frame structure and walking mechanisms are respectively set on both sides of it. A feeding mechanism is set in the middle of the frame. The feeding mechanism includes a storage box, two parallel rotating shafts, and multiple feeding components. The two ends of the rotating shafts are rotatably connected to the top of the side walls of the storage box, and the two rotating shafts are at the same height. Multiple feeding components are arranged sequentially on the outer walls of the two rotating shafts, and the feeding components of the two rotating shafts are staggered. The feeding components include a transmission block, a feeding screw, and a feeding tube. The transmission block is rotatably sleeved on the outer wall of the rotating shaft and has a drive cavity inside it (i.e., the rotating shaft passes through the transmission block and is rotatably connected to the side wall of the transmission block). The feeding screw is rotatably set at the bottom of the transmission block and is connected to the rotating shaft through a connecting mechanism set in the drive cavity. The feeding tube is set on the lower side of the bottom surface of the storage box corresponding to the feeding screw, and the bottom of the storage box has a through hole corresponding to the feeding tube. The bottom end of the feeding screw passes through the through hole and is located in the inner cavity of the feeding tube.

[0005] Based on further optimization of the above scheme, the walking mechanism adopts a tracked walking mechanism, and its operation is controlled by a servo motor mounted on the frame.

[0006] Based on further optimization of the above scheme, a drive shaft is set between the two rotating shafts in the inner cavity of the storage box. The two ends of the drive shaft are rotatably connected to the side wall of the storage box. The drive shaft is parallel to the rotating shaft and is located below the rotating shaft. One end of the drive shaft on the outer wall of the storage box is connected to the output shaft of the drive motor set on the outer side wall of the storage box, and the other end is fixedly sleeved with the drive wheel. The two ends of the two rotating shafts on the outer side of the storage box are respectively fixedly sleeved with the drive wheel, and the two drive wheels on the same side are connected to the drive wheel by a chain.

[0007] Based on further optimization of the above scheme, the trencher is positioned on the bottom surface of the machine frame, corresponding to the feed pipe.

[0008] Based on further optimization of the above scheme, the soil covering mechanism includes a lifting support assembly, a soil covering roller assembly, and a soil covering baffle. The lifting support assembly consists of two sets, including a lifting support, a top rod, a limiting block, and a spring. The lifting support is an L-shaped structure with an obtuse angle, and one end of the lifting support is rotatably connected to the bottom surface of the rear end of the frame. The soil covering roller assembly is located between the two lifting supports, and its two ends are rotatably connected to the corners of the L-shaped structures of the two lifting supports respectively. The soil covering baffle is fixedly located between the two lifting supports and at the end away from the frame. One end of the top rod is rotatably located on the end face of the lifting support between the soil covering roller assembly and the soil covering baffle, and the other end passes through the corresponding frame and is fixedly provided with a limiting block. A spring is provided between the frame and the lifting support and on the outer ring of the top rod.

[0009] Based on further optimization of the above scheme, the soil covering roller assembly includes a central shaft, fixed discs, soil covering rods and support rods. The two ends of the central shaft are respectively rotatably connected to the L-shaped corners of the two lifting supports. The central shaft is located on the outer wall between the two lifting supports and three fixed discs are evenly sleeved. Support rods are evenly arranged on the outer ring of the fixed discs and soil covering rods are arranged between the relative support rods of the three fixed discs. The soil covering rods are parallel to the central shaft.

[0010] Based on further optimization of the above scheme, the fixed disc is evenly perforated with circular holes around its central axis, which avoids soil adhesion during the covering process and reduces weight.

[0011] The following are the technical effects of this utility model: This invention employs a feeding assembly consisting of a transmission block, a feeding screw, and a feeding pipe. Utilizing a spiral guide, it achieves precise and quantitative feeding, preventing uneven feeding of morel mushrooms and thus avoiding problems such as low fruiting rate and uneven growth. Simultaneously, the sowing device, through the coordinated arrangement of multiple feeding assemblies staggered on two rotating shafts, enables simultaneous sowing in multiple furrows. This not only effectively improves sowing efficiency and reduces sowing time but also avoids mutual interference between sowing amounts in different furrows (i.e., the problem of duplicate sowing), ensuring precise and efficient sowing.

[0012] Furthermore, through the coordinated operation of the feeding mechanism, the furrow opener, and the soil covering mechanism, this invention achieves an integrated action of furrow opening, feeding, and soil covering during the movement of the sowing device, greatly improving the work efficiency of morel mushroom cultivation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: An integrated seeding device includes a frame 10, a feeding mechanism, a furrow opener 30, a soil covering mechanism, and a walking mechanism. The frame 10 adopts a frame structure with walking mechanisms on both sides. The walking mechanism is a tracked walking mechanism, and its operation is controlled by a servo motor mounted on the frame 10. The tracked walking mechanism is the power source for the seeding device. A common track assembly includes components such as a track tensioner, a load-bearing wheel, a track, a drive wheel, and a wheel frame. The use of a tracked walking trolley is mainly due to its good maneuverability, which facilitates passage through greenhouses. It has high stability; the low center of gravity and wide contact surface of the track enhance stability and reduce the risk of tipping over, making it suitable for uneven terrain. It has strong adaptability and can be used in harsh environments such as extreme temperatures, humidity, and corrosion, and is widely used in agriculture and other fields. The track distributes pressure, reducing damage to the ground, making it suitable for farmland and other situations where ground protection is required. It is flexible to operate; by independently controlling the tracks on both sides, it can achieve turning on the spot and flexible movement, making it suitable for operation in narrow spaces.

[0024] A feeding mechanism is installed in the middle of the frame 10. The feeding mechanism includes a storage bin 21, two parallel rotating shafts 22, and multiple feeding components. The two ends of the rotating shafts 22 are rotatably connected to the top of the side walls of the storage bin 21, and the two rotating shafts 22 are at the same height (e.g., Figure 1 or Figure 2As shown), a drive shaft 24 is located between two rotating shafts 22 within the inner cavity of the storage box 21. Both ends of the drive shaft 24 are rotatably connected to the side wall of the storage box 21. The drive shaft 24 is parallel to the rotating shaft 22 and is located below the rotating shaft 22. One end of the drive shaft 24 located on the outer wall of the storage box 21 is connected to the output shaft of the drive motor located on the outer side wall of the storage box 21 (thus driving the drive shaft 24 to rotate), and the other end is fixedly sleeved with a drive wheel. The two ends of the two rotating shafts 22 located on the outer side of the storage box 21 are respectively fixedly sleeved with drive wheels, and the two drive wheels on the same side are connected to the drive wheel by a chain (thus driving the two rotating shafts 22 to rotate synchronously and in the same direction through the rotation of the drive shaft 24).

[0025] Multiple sets of feeding components are sequentially arranged on the outer walls of the two rotating shafts 22, and the feeding components of the two rotating shafts 22 are staggered (e.g. Figure 1 or Figure 2 As shown, five sets of feeding assemblies are arranged on the outer wall of the left rotating shaft 22, and four sets of feeding assemblies are arranged on the outer wall of the right rotating shaft 22, with the gaps between the four sets of feeding assemblies and the five sets of feeding assemblies corresponding. The feeding assembly includes a transmission block 231, a feeding screw rod 232, and a feeding tube 233. The transmission block 231 is rotatably sleeved on the outer wall of the rotating shaft 22, and a driving cavity is provided inside it (i.e., the rotating shaft 22 passes through the transmission block 231, and the rotating shaft 22 is rotatably connected to the side wall of the transmission block 231, such as...). Figure 5 As shown; meanwhile, to prevent the transmission block 231 from rotating with the rotating shaft 22 and to ensure the stationary state of the transmission block 231, the transmission block 231 can be connected to the corresponding inner wall of the storage box 21 via a bracket, or it can be fixedly connected to the inner wall of the bottom end of the feeding funnel set on the upper side of the storage box 21. It can be adjusted according to the actual situation, and no further limitations are made in this embodiment; the feeding funnel adopts a structure with a large upper width and a small lower width. The feeding screw 232 is rotatably set at the bottom of the transmission block 231, and the feeding screw 232 is connected to the rotating shaft 22 through a connecting mechanism set in the drive cavity (the connecting mechanism can be a gear mechanism, such as...). Figure 5 As shown, the shaft 22 and the feeding auger 232 are connected and driven by a set of meshing bevel gears, which in turn drive the feeding auger 232 to feed material through the rotation of the shaft 22. The feeding augers 232 have the same direction of rotation and both adopt a right-handed structure (e.g., Figure 2 As shown), the pitch of the feeding screw 232 is 80mm; the feeding pipe 233 is located on the lower side of the bottom surface of the storage box 21 corresponding to the feeding screw 232, and the bottom surface of the storage box 21 has a through hole corresponding to the feeding pipe 233 (the diameter of the feeding pipe 233 is φ80mm). The bottom end of the feeding screw 232 passes through the through hole and is located in the inner cavity of the feeding pipe 233.

[0026] The trencher 30 is located on the bottom surface of the frame 10, corresponding to the feed pipe 233. (The trencher 30 can be a common trencher.)

[0027] The soil covering mechanism includes a lifting support assembly, a soil covering roller assembly 42, and a soil covering baffle 43. The lifting support assembly consists of two sets, including a lifting support 411, a top rod 412, a limiting block 413, and a spring 414. The lifting support 411 is an L-shaped structure with an obtuse angle (e.g., Figure 3 (As shown) and one end of the lifting bracket 411 is rotatably connected to the bottom rear end of the frame 10; the soil covering roller assembly 42 is disposed between the two lifting brackets 411 and its two ends are rotatably connected to the L-shaped corners of the two lifting brackets 411 respectively (as shown). Figure 3 As shown), the soil covering baffle 43 is fixedly installed between the two lifting supports 411 and located at the end away from the frame 10; one end of the top rod 412 is rotatably installed on the end face of the lifting support 411 between the soil covering roller mechanism 42 and the soil covering baffle 43, and the other end passes through the corresponding frame 10 and is fixedly installed with a limit block 413; a spring 414 is installed between the frame 10 and the lifting support 411 and on the outer ring of the top rod 412.

[0028] like Figure 4 As shown: The soil covering roller assembly 42 includes a central shaft 421, fixed discs 422, soil covering rods 423, and support rods 424. The two ends of the central shaft 421 are rotatably connected to the L-shaped corners of two lifting supports 411, and the central shaft 421 is located on the outer wall (along its axial direction) between the two lifting supports 411, where three fixed discs 422 are evenly fitted. Support rods 424 are evenly arranged around the outer ring of the fixed discs 422, and soil covering rods 423 are arranged between the relative support rods 424 of the three fixed discs (e.g., ...). Figure 4 As shown), the soil-covering rod 423 is parallel to the central axis 421. The fixed disc 422 has evenly spaced circular holes 4220 around the central axis (as shown). Figure 4 As shown, in this embodiment, four circular holes are opened on a fixed disc 422 to avoid soil adhesion during the covering process and reduce weight.

[0029] Working principle: The entire seeding device is controlled by a tracked walking mechanism, with a servo motor installed on each of its left and right sides as a power source (e.g., Figure 8 As shown in the figure, its movement speed is set to 50-55 m / min according to the requirements of morel substrate feeding; the two servo motors can very flexibly realize the various movements required by the seeder. Due to the flat design driven by the tracked walking trolley, the seeder working in the greenhouse has excellent passability, which can save labor costs and ensure the continuity of planting.

[0030] When sowing is required, the entire sowing device is driven to run on the sowing field. The lifting support ensures a safe distance between the feeding mechanism and the ground when the seeder travels on the road, preventing friction and damage to the covering mechanism. The uniformity and smooth feeding of substrate mycelium particles depend on the coordination of the pitch, rotation speed, and travel speed of the feeding screw 232 of the feeding mechanism. The successful growth of substrate mycelium is closely related to the structure, angle, and size of the opening device of the feeding mechanism, the tension of the tension spring of the covering mechanism, and the size and angle of the covering plate. The drive shaft 24 drives two rotating shafts 22 to rotate, thereby enabling all feeding screws 232 to rotate simultaneously and in the same direction. This allows the substrate material (i.e., substrate mycelium particles) in the storage box 21 to be guided into the feeding pipe 233 through the spiral blades of the feeding screws 232. After the furrow opener 30 opens the furrows, sowing is achieved, resulting in uniform, multi-furrow sowing. This ensures both sowing efficiency and uniformity, promoting the transformation of the morel mushroom cultivation industry towards high efficiency and intelligence, and increasing the profitability of morel mushroom cultivation. Finally, the covering mechanism rotates during operation to achieve soil covering.

[0031] Example 2: As another optimized embodiment of this utility model, based on the above-described embodiment 1, the trencher 30 can also employ a specific trenching component, such as... Figure 6 , Figure 7 As shown: The machine includes a positioning bracket 31, a mounting rod 32, a shock-absorbing spring 33, two trenching discs 34, an arc-shaped mudguard 35, and a scraper component 36. Two parallel mounting beams 11 are respectively installed on the middle of the bottom surface of the storage bin 21 of the frame 10. The mounting rod 32 is fixedly mounted on the mounting beams 11 via the positioning bracket 31. Two trenching discs 34 are symmetrically arranged at the end of the mounting rod 32 away from the positioning bracket 31 (i.e., the bottom end), and the two trenching discs 34 are rotatably mounted at the bottom end of the mounting rod 32. Initially, the longitudinal section of the two trenching discs 34 is a V-shaped structure (the farthest distance between the two trenching discs 34, i.e., the maximum width of the V-shaped structure). The feed pipe 233 is set between the two corresponding furrowing discs 34 and is located on the side of the corresponding furrow opener 30 near the soil covering mechanism (to ensure an automated sowing process of furrowing first and then sowing); the mounting rod is located on the outer wall of the side away from the feed pipe 233 and is slidably fitted with the arc-shaped mudguard 35, and the arc-shaped mudguard 35 is located on the upper side of the corresponding furrowing disc 34. The arc-shaped mudguard 35 is set between the positioning bracket 31 and the outer ring of the mounting rod 32 with a shock-absorbing spring 33. The side of the arc-shaped mudguard 35 near the feed pipe 233 has a scraper component 36, and the scraper component 36 is located on the outside of the two furrowing discs 34, for scraping off excess soil.
