[0045] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] like Figure 1-Figure 9 The embodiment of the present invention provides a fallen leaf picking, compressing and fertilizing treatment device, including a collecting device 1, a conveying device 2, a compressing device 3, a driving device 4, a packing device 5, and a screw compression mechanism 6, which are specifically configured as follows:

[0047] The collecting device 1 is mainly used to collect fallen leaves. The collecting device 1 includes a collecting mechanism and a screening mechanism.

[0048] like Figure 2 As shown, the collecting mechanism includes two screening rollers 11 connected to two first motors 13 through two transverse brackets 12 respectively, the first motor 13 is fixed below the shell 15, three ultrasonic sensor components 14 are fixed above the shell 15 through a base 142, a plurality of ultrasonic sensors 141 are provided on the ultrasonic sensor component 14, the ultrasonic sensor 141 is located above the base 142, the three ultrasonic sensor components 14 are symmetrically distributed, the ultrasonic sensor components 14 are used to detect obstacles in front to avoid them, and the first motor 13 drives the rotation of the transverse bracket 12 and the screening roller 11 to screen out stones in the fallen leaves.

[0049] like Figure 2 , Figure 3 and Fig. 9 As shown, the ultrasonic sensor 141 consists of three pairs, each pair includes a transmitting probe and a receiving probe, a total of six ultrasonic sensor heads. Therefore, the measurement range of the ultrasonic sensor 141 includes the space that it must pass through in the direction of travel, while avoiding detection of blind spots, that is, making the blind spot fall outside the range to be measured. It calculates and determines the relative position of the obstacle based on the amplitude of the received signal (left, middle, and right), and the time interval from transmission to reception, and then the single-chip computer system 70 outputs the corresponding control pulse to the motor controller to make an obstacle avoidance response.

[0050] like Figure 2As shown, the screening mechanism is located at the rear of the collecting mechanism, and the screening mechanism includes a large roller brush 16, a screen plate 17 and a small roller brush 18. The screen plate 17 is installed at the bottom of the housing 15. The screen plate 17 can vibrate along any direction of the housing 15. When it moves in the horizontal direction, the screening effect is the best. The large roller brush 16 and the small roller brush 18 are both fixed inside the housing 15, the large roller brush 16 is at the back, and the small roller brush 18 is at the front. The volume of the large roller brush 16 is larger than that of the small roller brush 18. At the same time, the bristles of the large roller brush 16 and the bristles of the small roller brush 18 are staggered and abutted. The large roller brush 16 and the small roller brush 18 are driven by a driving assembly. The large roller brush 16 and the small roller brush 18 perform secondary screening of stones in the fallen leaves by staggered matching or similar meshing.

[0051] The screening roller 11 is the main device for collecting fallen leaves, which is generally in the shape of a drum. The two screening rollers 11 form a V shape. The screening rollers 11 are driven by a DC motor to pre-process the fallen leaves to ensure the efficiency of picking up fallen leaves.

[0052] The collecting device 1 is equipped with a collecting mechanism and a screening mechanism, which can screen out sand and gravel in the fallen leaves and increase the collecting area, thereby improving the efficiency of picking up fallen leaves and further screening out gravel.

[0053] like Figure 4 and Figure 1 As shown, one end of the conveyor 2 is connected to the collecting device 1, and the other end of the conveyor 2 is connected to the compression device 3. The fallen leaves collected by the collecting device 1 will be gathered at the bottom of the conveyor belt 21, and then the conveyor belt 21 will transfer the fallen leaves to the compression device 3, wherein two DC motors will provide power for the conveyor belt 21, and the speed of the conveyor belt 21 can be changed by adjusting the voltage of the motor, so as to improve the conveying efficiency of the fallen leaves. At the same time, a plurality of baffles 22 are provided on the conveyor belt 21, and a hollow structure with an open top is formed between the plurality of baffles 22, and the baffles of the hollow structure can effectively screen out fine stones in the fallen leaves.

[0054] like Figure 5 and Figure 1 As shown, a storage box is provided inside the compression device 3 for storing the fallen leaves conveyed by the conveying device 2. In addition, the compression device 3 also includes an intermittent putrefactive bacterial liquid feeding mechanism, a screw compression mechanism 6, a pressure sensor 36 and a compression pressure plate 32; the pressure sensor 36 is arranged at the bottom of the storage box, and the compression pressure plate 32 is arranged at the middle and upper part of the storage box. The fallen leaves conveyed to the storage box by the conveying device 2 will gradually accumulate to trigger the pressure sensor 36; the screw motor 35 located at the top of the storage box receives the signal from the pressure sensor 36 to drive the screw 61 to rotate, and the compression pressure plate 32 is compressed downward with the screw. After the leaves are compressed into shape, the screw motor 35 is reversed, and the compression pressure plate 32 is lifted. The pressure sensor 36 can detect the quality of the fallen leaves in the storage box in real time, so as to facilitate the control of the working time of the compression device 3.

[0055] like Figure 3 and Figure 8 As shown, the intermittent decomposing bacterial liquid feeding mechanism includes a fertilizer contact nozzle 33 and a fertilizer storage box 34; the fertilizer storage box 34 is connected to the fertilizer contact nozzle 33, and the fertilizer storage box 34 is provided with an interior of the storage box for storing bacterial liquid. The interior of the fertilizer contact nozzle 33 is provided with a hydraulic pump, and the hydraulic pump is a hydraulic element that provides power for the bacterial liquid to be ejected from the fertilizer storage box 34. When the fallen leaf block touches the fertilizer contact nozzle 33, the bacterial liquid inside it is ejected, and the ejection dose of the bacterial liquid can be calculated by the control system 7 and the compression pressure plate 32 to compress the fallen leaf bricks of the same specifications. The intermittent decomposing bacterial liquid feeding mechanism will evenly sprinkle the bacterial liquid through the hydraulic pump during the compression process to ensure the complete decomposition of the fallen leaves. At the same time, the fertilizer storage box 34 and the lead screw 61 are connected to realize lifting and lowering, and the compression device 3 is cooperated to complete the packaging. The decomposing bacterial liquid can be sprayed in layers, which is helpful for the efficient and high-quality decomposition of the fallen leaves, and forms a more uniform and high-quality organic fertilizer. After the fallen leaves are compressed into shape, they need to be packed and sealed for decomposition, and the bags can be broken and fertilized in about a month.

[0056] like Figure 6 and Fig. 9 As shown, the driving device 4 realizes the speed regulation function of the car by using the synergistic effect of the single-chip control system 70 and the DC motor drive module 73. The multi-channel PWM signal given by the single-chip control system 70 controls each motor. The model of the DC motor drive module 73 is L298N. L298N is a dual H-bridge motor driver chip, in which each H-bridge can provide 2A of current, the power supply voltage range of the power part is 2.5-48v, the logic part is 5v powered, and accepts 5vTTL level. There are many driving modes for this device, such as wheeled, crawler and legged. Crawler robots have a large ground area and run smoothly. In combination with actual social production needs, this design adopts a crawler structure. According to the fallen leaf picking and compressing fertilizer processing machine, two left and right DC reduction motors plus crawler walking mechanisms are used, thereby forming a left-right symmetrical structure, which can not only realize forward and backward, but also realize curve walking when the left and right motor speeds are different.

[0057] The ultrasonic sensor module 71 rotates with the first motor 13 to realize the barrier scanning function within a range of 180 degrees, ensuring the safety of the machine during operation. To adapt to different working environments, the machine chassis adopts a crawler drive, and two DC reduction motors are used to provide sufficient power for the crawler 41.

[0058] like Figure 7 and Figure 5As shown, it also includes a packing device 5. After the pressure sensor 36 detects that the weight of the fallen leaf brick reaches the standard, it sends a signal to the steering gear 52 at the rear of the push rod, which drives the simple mechanical arm to perform telescopic movement. The steering gear 52 drives the automatic rear door to open and push the compressed fallen leaves to the rear end packing device 5. The double-sided synchronous belt 54 drives the packing roller 55 to move, which can complete the movement of the packing roller 55 around the fallen leaf block.

[0059] When the pressure sensor 36 detects that the weight of the fallen leaf bricks meets the standard, the information is fed back to the single-chip control system. The information collected after calculation and processing is transmitted to the push rod tail servo 52 installed at the bottom of the storage box in the form of PWM signal, which drives the simple mechanical arm to do telescopic movement. At the same time, the servo 52 located at the rear of the storage box drives the automatic rear door to open, and the compressed fallen leaves can be pushed to the rear end packaging device 5. There are synchronous pulleys at both ends of the packaging drum 55, which can rotate freely around the packaging drum 55. The single-sided synchronous belt 53 is fixed on the outer shell of the packaging device 5, and the double-sided synchronous belt 54 is wrapped on the synchronous pulley inside the packaging device 5. The packaging drum 55 is placed between the two synchronous belts. A knife holder groove 51 is provided at the front end of the packaging drum 55. The inner double-sided synchronous belt 54 is driven by the stepping motor 56 to move, and the double-sided synchronous belt 54 drives the packaging drum 55 to move, and the packaging drum 55 moves around the fallen leaf block. Driven by the stepper motor 56, the packaging device 5 moves to the working area and rotates along the compressed fallen leaves to pack. During the packaging process, the simple mechanical arm pushes the fallen leaf bricks to move. After the fallen leaf bricks have completely passed through the packaging machine, the first packaging is completed. The fallen leaf bricks are rotated 90° along the horizontal plane and sent back by the steering platform 57 at the rear. After the fallen leaf bricks have completely passed through the packaging machine, the second packaging is completed. The simple mechanical arm cooperates with the rotating steering platform 57 to push the fallen leaf bricks completely off the platform. The packaged fallen leaves fall to the ground, the rotating steering platform 57 is lifted, the rear door is closed, and subsequent work is carried out.

[0060] The front-end collecting device 1 collects fallen leaves through the collecting mechanism and the screening mechanism, and the fallen leaves enter the storage box of the fallen leaf compression device 3 through the conveying device 2. The screw compression mechanism 6 needs to ensure that the compression pressure plate 32 can generate a stable pressure of sufficient magnitude, so the screw 61 is used to drive the compression pressure plate 32, and the compression degree of the fallen leaves is detected by the pressure sensor 36 below. The compressed fallen leaf blocks fall into the automatic packaging device 5 through the horizontal push plate 31, and finally the collection task is completed.

[0061] like Fig. 9As shown, the control system 7 is divided into multiple control modules, namely, a single chip control system 70, an ultrasonic sensor module 71, a pressure sensor module 72, a DC motor drive module 73, a module to be developed 74, a walking mechanism module 75, and an execution module 76. The ultrasonic sensor module 71 controls the ultrasonic sensor 141, the module to be developed 74 is a control unit reserved for further developing new functions, the pressure sensor module 72 controls the pressure sensor 36, the walking mechanism module 75 controls the operation of the drive device 4, and the execution module 76 controls each servo and the first motor to implement each function.

[0062] The present invention realizes the automatic picking, compression and decomposition of fallen leaves through the analysis of the overall function and the optimization design of the mechanism. At the same time, the design of the front double roller brush and the disc-type leaf-collecting mechanism can ensure the efficiency of picking up fallen leaves and the forming rate of compressed fallen leaf bricks.

[0063] This equipment is different from the existing products for leaf cleaning and leaf treatment in my country. It completes the cleaning and collection of fallen leaves and the secondary harmless resource utilization of fallen leaves under the premise of ensuring cleanliness, labor saving and high efficiency, thereby restoring soil fertility, protecting the ecological environment and laying the foundation for creating ecological benefits.

[0064] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
