A garden trimming vehicle

Abstract

This application relates to a garden pruning vehicle, belonging to the field of garden machinery technology. The garden pruning vehicle includes a pruning device, a primary volume reduction device, an airflow generator, a dual-zone storage bin, and a secondary processing device. Waste generated by the pruning device is crushed by the primary volume reduction device and then automatically sorted using the differences in aerodynamic properties of different materials in a high-speed airflow generated by the airflow generator: heavier materials settle into the heavy material bin, while lighter materials are blown into the light material bin. The material in the heavy material bin can then enter the secondary processing device for fine crushing and compression. This application, by combining airflow sorting with secondary compression, achieves the classification, volume reduction, and efficient collection of garden waste, significantly improving the vehicle's loading efficiency, reducing unloading frequency, and effectively extending the continuous operation time per cycle.

Description

Technical Field

[0001] This application relates to the field of garden machinery and equipment, and in particular to a garden trimming vehicle. Background Technology

[0002] Currently, urban greening maintenance work commonly uses garden pruning vehicles to prune and pre-treat the branches and leaves of trees along roads, in communities, and in scenic areas. Conventional pruning vehicles usually integrate pruning and shredding functions, directly shredding the pruned branches and leaves and storing them in the vehicle's material bin. Once the bin is full, the materials are then transported and processed collectively.

[0003] However, as continuous operating time increases, the problem of frequent unloading due to the accumulation of shredded material becomes increasingly prominent, becoming a key bottleneck restricting the improvement of operating efficiency. Because the shredded garden waste is still relatively large in volume and has uneven density, the storage bin quickly fills with the loose material. To address this issue, the industry mainly attempts to extend operating time by configuring large-capacity storage bins, thereby increasing the single loading capacity. However, this results in excessively large vehicle dimensions, reduced maneuverability, and severely impacts the vehicle's passability in narrow community roads or complex terrain.

[0004] Regarding the aforementioned technologies, the inventors believe that they suffer from drawbacks such as low storage efficiency of crushed materials, large space occupation, and the need for vehicles to frequently travel between the work site and the unloading area, which seriously affects the overall continuity of operations and economic benefits. Utility Model Content

[0005] To address the problems of frequent unloading and low operating efficiency caused by material accumulation in existing garden trimming vehicles, this application provides a garden trimming vehicle.

[0006] The garden pruning vehicle provided in this application adopts the following technical solution: The garden pruning vehicle described in this application includes a pruning device, a primary volume reduction device, a dual-zone storage bin, an airflow generator, and a secondary processing device. The pruning device is used to prune garden branches and leaves, generating garden waste. The primary volume reduction device is connected to the pruning device and is used to collect the garden waste and reduce its volume to form a waste mixture. The airflow generator is connected to the primary volume reduction device and configured to separate the waste mixture into heavy and light materials. The dual-zone storage bin is connected to the airflow generator and is internally divided into a light material bin and a heavy material bin by a partition, wherein the light material is directed to the light material bin and the heavy material is directed to the heavy material bin. The secondary processing device is connected to the heavy material bin and is used to receive the heavy material from the heavy material bin and to crush and compact the heavy material.

[0007] By reducing the volume of heavy materials in two stages and storing them in separate zones, the utilization rate of storage space can be improved, which is expected to reduce the frequency of unloading and extend the duration of a single operation.

[0008] Optionally, the secondary processing device includes a crushing unit and a compression unit connected in sequence. The crushing unit is used to crush the heavy material to generate heavy crushed material, and the compression unit is used to compress the heavy crushed material.

[0009] By adopting the above technical solutions, the volume reduction effect and density of heavy materials can be further improved, and the processed block materials are easier to unload and utilize.

[0010] Optionally, a valve is provided between the discharge port of the heavy material silo and the inlet of the secondary processing device; the valve is used to control the heavy material to enter the secondary processing device from the heavy material silo.

[0011] By adopting the above technical solutions and setting valves, the material flow can be effectively controlled, which helps to ensure the stability and controllability of the system operation.

[0012] Optionally, to achieve automated control, a level sensor is also included, which is installed inside the heavy material silo; the valve is electrically connected to the level sensor; wherein, when the level sensor detects that the material in the heavy material silo has reached a preset amount, the valve opens and the secondary processing device is started.

[0013] By adopting the above technical solution, the secondary processing flow is automated, which can reduce manual intervention and improve operational efficiency and intelligence.

[0014] Optionally, the upper part of the heavy material silo has a square structure, and the lower part has a cone-shaped structure.

[0015] By adopting the above technical solution, the structure takes into account both storage volume and discharge smoothness, and uses gravity to guide the material to slide towards the discharge port.

[0016] Optionally, the inclination angle of the sidewall of the cone-shaped structure is greater than the angle of repose of the heavy material.

[0017] By adopting the above technical solutions, the risk of material blockage or bridging on the inner wall of the silo can be reduced, and the continuity of material discharge can be improved.

[0018] Optionally, the side wall of the heavy material silo is provided with an openable and closable feeding port for manually adding garden waste from the outside.

[0019] By adopting the above technical solutions, materials that do not require or are inconvenient to process through the primary volume reduction device can be directly fed into the silo, which greatly enhances the operational flexibility and applicable scenarios of the vehicle and improves the convenience of on-site work.

[0020] Optionally, a baffle is provided between the light material silo and the heavy material silo. The baffle is located above the partition; the angle of the baffle is adjustable to change the landing point of the light and heavy materials.

[0021] By adopting the above technical solution and adjusting the baffles, the separation effect of different materials can be optimized, and the adaptability of the equipment can be enhanced.

[0022] Optionally, the primary volume reduction device includes a cutting-type shredder with a fly knife and a bottom knife.

[0023] By adopting the above technical solution, a cutting shredder can efficiently process garden waste, providing a favorable material form for subsequent separation.

[0024] Optionally, the airflow generating device is a centrifugal fan, and the outlet of the centrifugal fan is located in the discharge channel of the primary volume reduction device, thereby using the airflow to blow the mixture into the dual-zone storage tank.

[0025] By adopting the above technical solution, this integrated design cleverly combines material conveying and airflow separation functions into one, simplifying the system structure and helping to improve efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By performing secondary crushing and compaction on the separated heavy materials and implementing zoned storage for light and heavy materials, the utilization rate of storage space is significantly improved, thereby reducing the unloading frequency and significantly extending the duration of a single continuous operation, greatly improving the overall operational efficiency.

[0027] 2. Through the linkage control of material level sensors and valves, the secondary processing process is automated. It can start and stop intelligently according to the material level without manual intervention, which not only optimizes energy consumption, but also improves the intelligence level and ease of operation of the equipment.

[0028] 3. By adopting a square structure at the top and a conical structure at the bottom for the heavy material silo, and optimizing the side wall inclination angle of the conical structure to be greater than the material's angle of repose, the risk of material blockage or bridging within the silo is reduced, which helps to ensure the stability and continuity of the entire system's operation.

[0029] 4. By setting adjustable baffles, the equipment can flexibly adapt to different types and different moisture levels of garden waste, which helps to achieve efficient and accurate separation of light and heavy materials under various working conditions, thus enhancing the equipment's versatility and reliability.

[0033] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0034] This application discloses a garden trimming vehicle. (Refer to...) Figure 1 The garden trimmer includes a trimming device 10 integrated into the vehicle body, a primary volume reduction device 20, an airflow generator 30, a dual-zone storage bin 40, and a secondary processing device 50.

[0035] Reference Figure 1 and Figure 2 The pruning device 10 first prunes the garden branches and leaves, and the resulting garden waste is then collected by the primary volume reduction device 20. In this embodiment, the primary volume reduction device 20 is a high-efficiency cutting shredder. The cutting shredder has high-speed rotating blades and fixed bottom blades inside, which can cut and crush the mixed branches and leaves, forming a smaller waste mixture. This step not only reduces volume but also provides a more ideal material state for subsequent airflow separation.

[0036] The crushed waste mixture is discharged from the discharge channel of the primary volume reduction device 20 and enters the high-speed airflow field generated by the airflow generator 30. In this embodiment, the airflow generator 30 is a centrifugal fan, which is located at the discharge port of the primary volume reduction device 20. While completing the material conveying, the airflow generator 30 also utilizes the differences in the aerodynamic characteristics of different materials to achieve material sorting.

[0037] Reference Figure 2When the airflow carries the mixture into the internal space of the dual-zone storage bin 40, the heavier materials with higher density and smaller windward area (such as wood chips and short branches with high moisture content) are less lifted by the airflow and will settle earlier due to gravity, falling directly into the heavy material bin 43 located at the front of the airflow path. Conversely, the lighter materials with larger surface area (such as dry leaves and small bark fragments) are easily lifted by the airflow and carried to a greater distance, flying over the partition 41 inside the dual-zone storage bin 40, and finally falling into the light material bin 42 located at the rear of the airflow path. To more accurately control the separation effect, an angle-adjustable baffle 44 is also provided above the partition 41. By changing its angle, the cutoff boundary of the airflow and the flight trajectory of the materials can be finely adjusted, thereby adapting to different humidity levels and different types of garden waste, ensuring the accuracy of separation.

[0038] The structural design of the heavy material silo 43 has also been optimized. Its upper part is a square structure to maximize the initial storage volume, while the lower part is designed as a conical structure 43a to facilitate material concentration and smooth discharge. To completely prevent material (especially damp sawdust) from adhering, bridging, or clogging the silo walls, the sidewall angle of the conical structure 43a is intentionally designed to be greater than the angle of repose of the material, for example, 50-60 degrees, ensuring that the material can smoothly slide to the discharge port 43b at the bottom solely by gravity. Furthermore, to enhance operational flexibility, the heavy material silo 43 also has an openable and closable feed port (not shown in the figure) on its sidewall, allowing operators to manually add large pieces of waste that do not require primary crushing or are difficult to collect directly from the outside.

[0039] The core optimization of this invention lies in the deep processing of heavy materials. The discharge port 43b of the heavy material silo 43 is connected to the inlet of the secondary processing device 50 via a valve 60. The entire secondary processing process is intelligently and automatically controlled. A material level sensor 70 is installed inside the heavy material silo 43, which monitors the accumulation height of the material in the silo in real time. When the material reaches a preset threshold (e.g., 80% of the silo volume), the sensor sends a signal, automatically triggering the valve 60 to open and simultaneously starting the secondary processing device 50 to begin operation.

[0040] The heavy material entering the secondary processing unit 50 undergoes two consecutive processing stages. First, the material enters an internal crushing unit (not shown in the figure) for secondary fine crushing, producing heavier crushed material with more uniform particle size. Subsequently, this heavier crushed material is fed into a subsequent compression unit (not shown in the figure), where it is pressed into a regular-shaped, high-density block. Preferably, the high-density block is in the form of a block or brick. In this embodiment, the compression ratio of the compression unit is 4:1. This crushed and then compacted material not only has its volume compressed to the extreme but also has a regular shape, greatly facilitating subsequent unloading, transportation, and resource utilization.

[0041] In summary, this embodiment achieves highly efficient end-to-end operations for garden waste, from pruning, primary volume reduction, airflow separation, and zoned storage to automated secondary deep volume reduction of heavy materials. This series of designs significantly improves the vehicle's single-operation continuous capacity and reduces the number of trips to the unloading site, thereby greatly improving overall operational efficiency and economic benefits.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
