Description

Technical Field

[0001] The invention relates to the field of garden fallen leaves collection, in particular to an automatic classification and collection device for garden fallen leaves. Background Art

[0002] The accumulation of fallen leaves can easily affect the cleanliness of garden landscapes, especially in public places such as parks, scenic areas, and campuses. Prompt collection of fallen leaves can maintain the cleanliness and orderliness of green spaces and trails, improving environmental quality. Currently, automated equipment for collecting fallen leaves in gardens is widely used, but significant technical bottlenecks still exist in its actual operation.

[0003] While existing devices can achieve initial collection of fallen leaves, they generally face the problem of fluffy leaves and limited collection capacity. Due to the loose and porous structure of fallen leaves, traditional collection equipment simply stores them in a simple storage compartment without effectively compressing them, resulting in extremely low storage space utilization. For example, a storage compartment with a volume of 1 cubic meter can only hold 30-50 kilograms of fluffy fallen leaves, requiring frequent emptying, which seriously affects operational efficiency. Based on this, we have proposed an automated sorting and collection device for garden fallen leaves. Summary of the Invention

[0004] In order to solve the technical problems that fallen leaves become fluffy after being collected and the actual collection amount is limited, the present invention provides an automatic classification and collection device for garden fallen leaves.

[0005] The present invention is implemented by the following technical solution: an automatic sorting and collecting device for garden fallen leaves, comprising a device frame, a bottom end of the device frame being rotatably connected to a moving wheel, a collecting mechanism being movably connected to the device frame, a fallen leaf conveying mechanism being installed on the device frame, and a fallen leaf squeezing mechanism being installed inside the device frame; The collection mechanism includes a drive motor, the output shaft of which is connected to a first rotating wheel. One end of the collection mechanism chain belt is sleeved on the surface of the first rotating wheel, and the other end of the collection mechanism chain belt is connected to a rotating gear. The outer side of the rotating gear is meshed with a moving gear. The surface of the moving gear is connected to a slave rotating wheel. One end of the installation chain belt is sleeved on the surface of the slave rotating wheel, and the other end of the installation chain belt is sleeved on a rotating bearing. The inner side of the rotating bearing is penetrated by a rotating frame, and the frame body of the rotating frame is sleeved on a fixed shaft sleeve. The outer side of the rotating frame is fixedly connected to a collection frame. A collection plate is installed at the front end of the device frame, and the collection frame is located above the collection plate. A collection brush is fixedly connected to the surface of the collection frame. The collection brush is a flexible brush that fits against the bottom wall of the collection plate.

[0006] The fallen leaf conveying mechanism includes a conveyor chain belt, one end of which is sleeved on the surface of the first rotating wheel, and the other end of which is sleeved on the conveying rotating wheel. A conveyor roller passes through the inner axis of the conveying rotating wheel, and the surface of the conveyor roller is sleeved with a conveyor belt for conveying fallen leaves. One end of the conveyor roller is connected to the conveying rotating wheel, and the other end is connected to the connecting rotating wheel. One end of the extrusion mechanism chain belt is sleeved on the surface of the connecting rotating wheel, and the other end of the extrusion mechanism chain belt is sleeved on the rotating wheel.

[0007] Among them, the fallen leaf squeezing mechanism includes a rotating wheel disc, a first bevel gear is connected to the wheel axis of the rotating wheel disc, a second bevel gear is vertically meshed with the outer side of the first bevel gear, a connecting rod is movably passed through the center of the second bevel gear, the top of the connecting rod passes through the fixed frame, the top of the connecting rod is connected to one end of the deflection block, the other end of the deflection block is connected to the deflection axis block, the outside of the deflection axis block is connected to the deflection shaft, the other end of the deflection shaft is connected to the fixed axis block, the inner side of the fixed axis block is installed and connected with a sleeve, the inner side of the sleeve is fixedly connected to a telescopic sub-frame, the bottom end of the telescopic sub-frame is inserted into the interior of the telescopic main frame, and the top of the telescopic sub-frame is fixedly connected to the squeezing plate.

[0008] As the rotating wheel rotates with the chain belt, it drives the coaxially mounted first bevel gear to rotate synchronously. The first bevel gear meshes vertically with the second bevel gear, converting horizontal rotational motion into vertical rotational motion of the second bevel gear, driving the connecting rod to rotate around its axis.

[0009] The top end of the connecting rod is fixedly connected to the deflection block, forming a "crank" structure; the other end of the deflection block is hinged to the deflection shaft through the deflection axis block, forming a "connecting rod." The end of the deflection shaft is connected to the fixed axis block, and its inner side is rigidly connected to the telescopic subframe through a sleeve, forming a "slider" assembly.

[0010] As a further optimization solution of the present invention, a collecting bin is fixedly installed inside the device frame, the extrusion plate is placed inside the extrusion plate, and the telescopic sub-frame passes through the bin body surface of the collecting bin.

[0011] As a further optimization solution of the present invention, the power of the fallen leaf squeezing mechanism comes from the terminal transmission component of the fallen leaf conveying mechanism and the rotating wheel, which is connected to the rotating wheel through the squeezing mechanism chain to form a power transmission link.

[0012] As a further optimization solution of the present invention, the bottom end of the telescopic main frame is fixedly installed above the frame body of the fixed frame, the telescopic sub-frame is connected to the inner side of the telescopic main frame, and the telescopic sub-frame performs telescopic operation on the inner side of the telescopic main frame.

[0013] As a further optimization scheme of the present invention, when the telescopic sub-frame moves linearly, the extrusion plate enters the collection bin and applies pressure to the accumulated fallen leaves; the sliding cooperation between the telescopic sub-frame and the telescopic main frame is used to achieve stable extrusion, compressing the fluffy fallen leaves to a high-density state, thereby increasing the capacity of the collection bin.

[0014] As a further optimization of the present invention, the collecting plate is arc-shaped, and limit plates are installed on both sides of the collecting plate to prevent fallen leaves from falling. The collecting plate is designed in an arc shape, and the limit plates on both sides prevent the fallen leaves from scattering, forming a centralized collection area.

[0015] As a further optimization of the present invention, a drive motor drives the first rotating wheel, which transmits power to the rotating gear via the collection mechanism chain belt. After the moving gears engage and transmit power, the slave rotating wheel rotates, which in turn drives the rotating bearing and the rotating frame via the mounting chain belt. The collection frame body outside the rotating frame rotates with it, causing the collection brush to reciprocate across the bottom wall of the collection plate, gathering fallen leaves on the ground into the collection plate area.

[0016] As a further optimization of the present invention, the first rotating wheel drives the conveyor rotating wheel via the conveyor mechanism chain belt, which drives the conveyor roller to rotate, causing the conveyor belt to run at a set speed. The fallen leaves swept up by the collection brush are pushed onto the conveyor belt, which transports the fallen leaves to the top of the collection bin inside the device.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses a fallen leaf squeezing mechanism to convert the rotational motion into the reciprocating motion of the squeezing plate through a crank-connecting rod structure, periodically squeezing the fallen leaves in the collection bin, and utilizing the sliding cooperation between the telescopic sub-frame and the main frame to achieve stable compaction, thereby improving the space utilization rate of the storage bin and reducing the frequency of dumping.

[0018] 2. The present invention drives the motor to link the collection mechanism and the conveying mechanism, uses the collection brush to sweep back and forth and the conveyor belt to convey continuously, and realizes the automation of the entire process of sweeping fallen leaves from the ground to the collection bin. No human intervention is required, which greatly improves the working efficiency and is especially suitable for large-scale garden scenes.

[0019] 3. In the present invention, the power of each mechanism is derived from a single drive motor, and synchronous operation is achieved through chain belts, gears, and transmission, avoiding energy waste from multiple power sources; the power of the extrusion mechanism is taken from the connecting wheel at the end of the conveying roller, without the need for additional power input, further reducing energy consumption.

[0020] 4. The present invention uses a collection brush made of flexible material and fits the bottom wall of the arc-shaped collection plate to reduce the omission of fallen leaves; the limit plate and the guide slope design prevent the fallen leaves from splashing, thereby improving the collection efficiency.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0024] Please combine Figure 1 as well as Figure 5-Figure 6 This embodiment provides an automated garden leaf sorting and collection device, comprising a device frame 1, a moving wheel 2 rotatably connected to the bottom end of the device frame 1, a collecting mechanism 3 movably connected to the device frame 1, a leaf conveying mechanism 4 installed on the device frame 1, and a leaf squeezing mechanism 5 installed inside the device frame 1; Among them, the fallen leaf squeezing mechanism 5 includes a rotating wheel disc 51, a first bevel gear 52 is connected to the wheel axis of the rotating wheel disc 51, a second bevel gear 53 is vertically meshed with the outer side of the first bevel gear 52, a connecting rod 54 is movably passed through the center of the second bevel gear 53, the top of the connecting rod 54 passes through the fixed frame 55, the top of the connecting rod 54 is connected to one end of the deflection block 56, the other end of the deflection block 56 is connected to the deflection axis block 57, the outer side of the deflection axis block 57 is connected to the deflection shaft rod 58, the other end of the deflection shaft rod 58 is connected to the fixed axis block 59, the inner side of the fixed axis block 59 is installed and connected with a sleeve 510, the inner side of the sleeve 510 is fixedly connected to a telescopic sub-frame 511, the bottom end of the telescopic sub-frame 511 is inserted into the inside of the telescopic main frame 512, and the top of the telescopic sub-frame 511 is fixedly connected to an extrusion plate 513.

[0025] The bottom end of the telescopic main frame 512 is fixedly installed above the frame body of the fixed frame 55, and the telescopic sub-frame 511 is connected to the inner side of the telescopic main frame 512. The telescopic sub-frame 511 performs telescopic operation on the inner side of the telescopic main frame 512.

[0026] The collecting bin 6 is fixedly installed inside the device frame 1 , the squeezing plate 513 is placed inside the squeezing plate 513 , and the telescopic sub-frame 511 passes through the bin surface of the collecting bin 6 .

[0027] In a more specific technical solution, the power of the fallen leaf squeezing mechanism 5 comes from the terminal transmission component of the fallen leaf conveying mechanism 4 and the rotating wheel 45, which is connected to the rotating wheel 51 through the squeezing mechanism chain belt 46 to form a power transmission chain.

[0028] When the rotating wheel 51 rotates with the chain belt, it drives the coaxially mounted first bevel gear 52 to rotate synchronously. The first bevel gear 52 is vertically meshed with the second bevel gear 53, converting the horizontal rotational motion into the vertical rotational motion of the second bevel gear 53, driving the connecting rod 54 to rotate around the axis.

[0029] The top end of connecting rod 54 is fixedly connected to deflection block 56, forming a "crank" structure. The other end of deflection block 56 is hinged to deflection shaft 58 via deflection axis block 57, forming a "connecting rod." The end of deflection shaft 58 is connected to fixed axis block 59, the inner side of which is rigidly connected to telescopic subframe 511 via sleeve 510, forming a "slider" assembly.

[0030] The deflection axis block 57 drives the deflection shaft 58 to swing back and forth. The swinging of the deflection shaft 58 forces the fixed axis block 59 and the sleeve 510 to move back and forth horizontally, thereby driving the telescopic sub-frame 511 to perform linear telescopic motion within the telescopic main frame 512. As the telescopic sub-frame 511 moves linearly, the compression plate 513 enters the collection bin 6, applying pressure to the accumulated fallen leaves. The sliding cooperation between the telescopic sub-frame 511 and the telescopic main frame 512 achieves stable compression, compressing the fluffy fallen leaves to a high density and increasing the collection bin capacity. Example

[0031] See also Figure 2-Figure 4 Example 2 further provides a collection mechanism 3 and a fallen leaf conveying mechanism 4. A collection plate 7 is mounted at the front end of the device frame 1, with a collection frame 310 positioned above the collection plate 7. The collection plate 7 is curved, and two side plates are mounted on the collection plate 7 to prevent fallen leaves from falling. The curved design of the collection plate 7, combined with the two side plates, prevents fallen leaves from scattering, forming a centralized collection area.

[0032] The collecting mechanism 3 includes a driving motor 31, the output shaft of which is connected to a first rotating wheel 32, the surface of which is sleeved with one end of a collecting mechanism chain belt 33, the other end of which is connected to a rotating gear 34, the outer side of which is meshed with a moving gear 35, the surface of which is connected to a slave rotating wheel 36, the surface of which is sleeved with one end of a mounting chain belt 37, the other end of which is sleeved with a rotating bearing 38, the inner side of which is penetrated by a rotating frame 39, the frame body of which is sleeved on a fixed shaft sleeve 391; The outer side of the rotating frame 39 is fixedly connected to a collecting frame 310, and the surface of the collecting frame 310 is fixedly connected to a collecting brush 311. The collecting brush 311 is a flexible brush, and the collecting brush 311 is attached to the bottom wall of the collecting plate 7.

[0033] Specifically, the device moves via the motion wheel 2 at the bottom of the device frame 1. Upon reaching the leaf collection area, the collection mechanism 3 activates: a drive motor 31 drives the first rotating wheel 32, which transmits power to the rotating gear 34 via the collection mechanism chain 33. After the motion gear 35 engages, it drives the slave rotating wheel 36, which in turn rotates the rotating bearing 38 and the rotating frame 39 via the mounting chain 37. The collection frame 310 on the outside of the rotating frame 39 rotates with it, causing the collection brush 311 to sweep back and forth across the bottom wall of the collection plate 7, gathering the fallen leaves on the ground into the collection plate 7 area.

[0034] The fallen leaf conveying mechanism 4 includes a conveying mechanism chain belt 41. One end of the conveying mechanism chain belt 41 is sleeved on the surface of the first rotating wheel 32. The other end of the conveying mechanism chain belt 41 is sleeved on the conveying rotating wheel 42. A conveying roller 43 passes through the inner axis of the conveying rotating wheel 42. The surface of the conveying roller 43 is sleeved with a conveyor belt 44 for conveying fallen leaves. One end of the conveying roller 43 is connected to the conveying rotating wheel 42, and the other end is connected to the connecting rotating wheel 45. The surface of the connecting rotating wheel 45 is sleeved with one end of the extrusion mechanism chain belt 46. The other end of the extrusion mechanism chain belt 46 is sleeved on the rotating wheel 51.

[0035] In a further technical solution, the first rotating wheel 32 drives the conveyor rotating wheel 42 through the conveyor mechanism chain belt 41, which drives the conveyor roller 43 to rotate, causing the conveyor belt 44 to run at a set speed. The fallen leaves swept by the collection brush 311 are pushed onto the conveyor belt 44, which transports the fallen leaves to the top of the collection bin 6 inside the device.

[0036] The working principle of the automatic classification and collection device for garden fallen leaves described in this patent is as follows: 1. Overall movement and fallen leaf collection stage The device moves via the motion wheel 2 at the bottom of the device frame 1. When it reaches the fallen leaf collection area, the collection mechanism 3 starts: The driving motor 31 drives the first rotating wheel 32 to rotate, transmits power to the rotating gear 34 through the collection mechanism chain belt 33, and after the moving gear 35 engages and transmits, drives the slave rotating wheel 36 to rotate, and then drives the rotating bearing 38 and the rotating frame 39 to rotate through the installation chain belt 37.

[0037] The collecting frame 310 outside the rotating frame 39 rotates with it, so that the collecting brush 311 sweeps back and forth on the bottom wall surface of the collecting plate 7, gathering the fallen leaves on the ground to the collecting plate 7 area.

[0038] The collecting plate 7 is designed in an arc shape, and cooperates with the limiting plates on both sides to prevent fallen leaves from scattering, forming a centralized collection area.

[0039] 2. Fallen leaf transportation stage The fallen leaf conveying mechanism 4 and the collecting mechanism 3 operate in conjunction with each other: The first rotating wheel 32 drives the conveying rotating wheel 42 through the conveying mechanism chain belt 41, driving the conveying roller 43 to rotate, so that the conveyor belt 44 runs at a set speed.

[0040] The fallen leaves swept up by the collecting brush 311 are pushed onto the conveyor belt 44, and the conveyor belt 44 transports the fallen leaves to the top of the collecting bin 6 inside the device.

[0041] 3. Leaf falling and squeezing stage The power of the fallen leaf squeezing mechanism 5 comes from the terminal transmission component of the fallen leaf conveying mechanism 4, which is connected to the rotating wheel 45 through the squeezing mechanism chain belt 46 to form a power transmission link.

[0042] When the rotating wheel 51 rotates with the chain belt, it drives the coaxially mounted first bevel gear 52 to rotate synchronously. The first bevel gear 52 is vertically meshed with the second bevel gear 53, converting the horizontal rotational motion into the vertical rotational motion of the second bevel gear 53, driving the connecting rod 54 to rotate around the axis.

[0043] The top end of connecting rod 54 is fixedly connected to deflection block 56, forming a "crank" structure. The other end of deflection block 56 is hinged to deflection shaft 58 via deflection axis block 57, forming a "connecting rod." The end of deflection shaft 58 is connected to fixed axis block 59, the inner side of which is rigidly connected to telescopic subframe 511 via sleeve 510, forming a "slider" assembly.

[0044] The deflection axis block 57 drives the deflection shaft 58 to swing back and forth. The swinging of the deflection shaft 58 forces the fixed axis block 59 and the sleeve 510 to move back and forth horizontally, thereby driving the telescopic sub-frame 511 to perform linear telescopic motion within the telescopic main frame 512. As the telescopic sub-frame 511 moves linearly, the compression plate 513 enters the collection bin 6, applying pressure to the accumulated fallen leaves. The sliding cooperation between the telescopic sub-frame 511 and the telescopic main frame 512 achieves stable compression, compressing the fluffy fallen leaves to a high density and increasing the collection bin capacity.

[0045] 4. Linkage Control and Efficiency Optimization The power of each mechanism comes from the drive motor 31, and synchronous linkage is achieved through transmission components such as chains and gears. No additional power source is required, which simplifies the structure and reduces energy consumption.

[0046] In summary, the present invention realizes synchronous operation by deriving the power of each mechanism from a single drive motor (31) through the transmission of chain belts (33, 41, 46) and gears (34, 35), thereby avoiding energy waste from multiple power sources; the power of the extrusion mechanism (5) is taken from the connecting wheel (45) at the end of the conveying roller (43), and no additional power input is required, thereby further reducing energy consumption.

[0047] The movement of the fallen leaves squeezing mechanism 5 ensures that the fallen leaves are collected and compressed at the same time, thus avoiding accumulation and clogging.

[0048] The flexible collecting brush 311 fits the bottom wall of the collecting plate 7 and can adapt to different ground flatness, thereby improving the efficiency of leaf cleaning and reducing wear on the ground.

[0049] Through the above process, the device realizes fully automated operation of fallen leaf collection, transportation and squeezing, effectively solving the problem of small collection volume and frequent dumping of traditional equipment.

[0050] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
