[0057] Please see Figure 1-5 The present invention provides a technical solution: the branch and leaf collection and crushing device of the green belt pruning vehicle includes a collection box 1, a screw conveyor 2, a dust collection device 3, a crushing feed hopper 4, mounting legs 5, a power supply 6, an inverted V-shaped cover 7, and a support rod 8.

[0058] A screw conveyor 2 is fixedly connected to the top surface of the collection box 1. The screw conveyor 2 has a screw compression section 26 at its lower end for compressing the crushed branches and leaves. The upper ends of the front and rear side walls of the screw conveyor 2 are fixedly connected to crushing feed hoppers 4 for collecting and crushing the pruned branches and leaves. A dust collection device 3 is fixedly connected to the side wall of the collection box 1. The negative pressure suction generated by the dust collection device 3 acts on the upper end of the crushing feed hopper 4 through the screw conveyor 2, forming a negative pressure area at the opening of the crushing feed hopper 4, which effectively adsorbs the scattered branch and leaf debris. An inverted V-shaped cover 7 is fixedly installed in the middle of the top surface of the two crushing feed hoppers 4 to guide the branches and leaves into the crushing feed hopper 4 and prevent them from splashing out.

[0059] In some embodiments, the screw conveyor 2 includes a cylinder 21, a feed inlet 22, a first drive motor 23, a round rod 24, an auger 25, and a screw compression section 26.

[0060] The top surface of the cylinder 21 is sealed, and its lower end is fixedly connected to the top surface of the collection box 1. The upper end of the outer wall of the cylinder 21 has inlet ports 22 on both the front and rear sides. The lower ends of the two crushing feed hoppers 4 are fixedly connected to the inlet ports 22 on the same side. The top surface of the cylinder 21 is fixedly equipped with a first drive motor 23. The lower end of the output of the first drive motor 23 passes through the top surface of the cylinder 21 and is fixedly connected to a round rod 24. The middle and lower ends of the outer wall of the round rod 24 are fixedly sleeved with an auger 25. The lower end of the auger 25 has a reduced pitch to form a spiral compression section 26. The first drive motor 23 drives the auger 25 to rotate, which spirally conveys the crushed branches and leaves downward and compresses them through the spiral compression section 26. The compressed branches and leaves are sent into the collection box 1.

[0061] In some embodiments, the crushing feed hopper 4 includes a rectangular frame 41, a conical hopper 42, a moving roller 43, a second drive motor 44, a crushing rod 45, and a fixed roller 46.

[0062] A conical hopper 42 is fixedly connected to the lower end of a rectangular frame 41. The lower end of the conical hopper 42 is inclined toward the cylinder 21 and fixedly connected to the feed inlet 22 on the same side. A fixed circular roller 46 is fixedly mounted on the left side of the front and rear side walls of the inner cavity of the rectangular frame 41, and a movable circular roller 43 is rotatably mounted on the right side. A second drive motor 44 is fixedly mounted on the front wall of the rectangular frame 41 corresponding to the movable circular roller 43. The output rear end of the second drive motor 44 is coaxially fixedly connected to the front end of the movable circular roller 43. Crushing rods 45 are evenly fixed on the outer walls of the fixed circular roller 46 and the movable circular roller 43, and the crushing rods 45 on the outer walls of the fixed circular roller 46 and the movable circular roller 43 are staggered. The second drive motor 44 drives the movable circular roller 43 to rotate, and cooperates with the fixed circular roller 46. The staggered crushing rods 45 crush the falling branches and leaves. The crushed branches and leaves are guided into the screw conveyor 2 through the conical hopper 42.

[0063] In some embodiments, the dust collection device 3 includes a first housing 31, a sealing cover 32, a handle 33, a mesh plate 34, a blower 35, a mesh cage 36, a cloth bag 37, a discharge hopper 38, and a discharge pipe with a valve 39.

[0064] The first box 31 has an opening at its upper end, and a sealing cover 32 is fastened to its upper end. A handle 33 is fixedly mounted on the top surface of the sealing cover 32 for easy opening and closing. The collection box 1 has an opening on its side wall, and the first box 31 is pasted and sealed at the opening of the side wall of the collection box 1. A mesh plate 34 is fixedly mounted on the side wall of the first box 31 corresponding to the opening of the collection box 1 to intercept large branches and leaves. A blower 35 is fixedly connected to the outer wall of the first box 31 away from the opening of the side wall of the collection box 1. A wire cage 36 is provided inside the first box 31. The wall is fixedly connected to the input end of the induced draft fan 35. A cloth bag 37 is fitted onto the outer wall of the mesh cage 36. The opening of the cloth bag 37 is sealed and pasted onto the outer wall of the input end of the induced draft fan 35. When the induced draft fan 35 is working, the air and fine dust in the collection box 1 are sucked into the first box 31. Large branches and leaves are intercepted by the mesh plate 34. Dust and small particulate impurities are filtered by the cloth bag 37, and clean air is discharged. A discharge hopper 38 is fixedly connected to the lower end of the first box 31. A discharge pipe 39 with a valve is fixedly connected to the lower end of the discharge hopper 38 for periodically cleaning the collected dust.

[0065] More specifically, an external controller is set up to be powered by a power supply 6, which is a rechargeable battery. The external controller controls the induced draft fan 35 to work intermittently. When the ventilation stops intermittently, the crushed branches and leaves that are attached to the screen plate 34 due to suction fall off due to gravity, so as to avoid the crushed branches and leaves from blocking the screen plate 34. After the branches and leaves form a blockage, the ventilation stops intermittently for the second time, and so on.

[0066] Understandably, the compressed and crushed branches and leaves are not easily dispersed under the negative pressure suction, which reduces the number of crushed branches and leaves adhering to the mesh plate 34 due to suction, so that the working time is long enough during intermittent control to ensure that sufficient negative pressure suction is generated.

[0067] In some embodiments, the collection box 1 includes a second box body 11, an inlet / outlet window 12, a baffle 13, and a latch 14.

[0068] The second housing 11 has an inlet / outlet window 12 on the side away from the dust collection device 3. A baffle 13 is hinged to the lower end of the inlet / outlet window 12. Pins 14 are installed between the upper front and rear sides of the baffle 13 and the outer wall of the second housing 11 to fix the baffle 13. Rubber pads are pasted and fixed at the edge of the inlet / outlet window 12. When the baffle 13 is fastened, it fits the rubber pads to improve the sealing. After the work is completed, the baffle 13 can be opened to clean the branches and leaves collected inside the second housing 11.

[0069] In some embodiments, a power supply 6 is fixed to the outer wall of the collection box 1. The power supply 6 is electrically connected to the first drive motor 23 of the screw conveyor 2, the blower 35 of the dust collection device 3 and the second drive motor 44 of the crushing feed hopper 4, respectively, to supply power to each electrical component.

[0070] In some embodiments, mounting legs 5 are uniformly fixedly mounted on the bottom surfaces of the collection box 1 and the dust collection device 3. The lower end of the mounting legs 5 is provided with connecting ear plates for fixing the entire device on the green belt trimming vehicle. During installation, the crushing feed hopper 4 is placed below the trimming blades in conjunction with trimming blades of a specific length and angle so as to collect the trimmed branches and leaves.

[0071] In some embodiments, a support rod 8 is fixed between the lower end of the crushing feed hopper 4 and the top surface of the collection box 1 to improve the installation and fixing strength of the crushing feed hopper 4 and ensure working stability.

[0072] The working process is as follows: When the green belt pruning vehicle performs pruning operations, the pruned branches and leaves fall into the crushing feed hopper 4. The inverted V-shaped cover 7 guides the branches and leaves to fall into the crushing feed hoppers 4 on both sides. The second drive motor 44 drives the moving roller 43 to rotate, which cooperates with the fixed roller 46 to crush the branches and leaves through the crushing rod 45. The crushed branches and leaves enter the feed inlet 22 of the screw conveyor 2 through the conical hopper 42. The first drive motor 23 drives the auger 25 to rotate, which spirals the branches and leaves downward and compresses them in the spiral compression section 26. After compression... The branches and leaves are sent into the second box 11 of the collection box 1. At the same time, the blower 35 of the dust collection device 3 works intermittently, creating a negative pressure in the collection box 1 and the screw conveyor 2. The negative pressure suction acts on the upper end of the crushing feed hopper 4 through the screw conveyor 2, adsorbing the scattered branches and leaf debris and preventing secondary pollution. The dust and small particulate impurities in the collection box 1 are sucked in and filtered by the dust collection device 3. After the work is completed, the baffle 13 is opened to clean the branches and leaves in the collection box 1, and the dust in the dust collection device 3 is cleaned regularly through the discharge pipe 39 with a valve.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
