Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a self-propelled arched greenhouse mulching and spraying integrated machine. Background Technology

[0002] In modern agricultural planting, greenhouse planting technology is widely used due to its good heat preservation and moisture retention properties. In order to ensure the normal growth of crops and prevent pests and diseases, farmers need to carry out operations such as mulching and spraying pesticides. However, most existing agricultural machinery has relatively limited functions and can only perform mulching or spraying operations alone. This means that to complete the entire planting and maintenance process, different machines need to be changed or carried out in batches, which leads to complicated operation links, greatly increases labor and time costs, and results in low production efficiency.

[0003] Furthermore, due to the special nature of the greenhouse planting environment, there are often raised ridges on the ground and erected greenhouse supports. This requires the operating machinery to have good mobility. However, the chassis height of existing self-propelled agricultural machinery is fixed and insufficient. When crossing greenhouses or taller crops, it may scrape and damage the facilities or crops. At the same time, the planting ridge spacing varies greatly in different regions or for different crops. The wheel track of traditional machinery is mostly a fixed structure that cannot be adjusted, making it difficult for the machinery to adapt to the requirements of different ridge spacing widths. It has poor versatility and cannot meet the diverse needs of agricultural production.

[0004] Therefore, this utility model proposes a self-propelled arched greenhouse mulching and pesticide spraying integrated machine to overcome the shortcomings of the existing technology. Utility Model Content

[0005] In view of the problems in existing agricultural machinery, such as the single function of existing agricultural machinery, which requires separate operations for mulching and spraying, resulting in low efficiency, and the fixed chassis height and wheel track of existing agricultural machinery, which cannot adapt to the operation requirements of different height arched greenhouses and different ridge spacing, and may damage crops, this utility model aims to provide a self-propelled arched greenhouse mulching and spraying integrated machine with improved structure that can effectively solve the above problems.

[0006] This utility model provides a self-propelled arched greenhouse mulching and spraying integrated machine, including a frame, a lifting mechanism fixedly connected to the bottom of the frame, and an engine fixedly installed on the top of the frame.

[0007] The raised front axle and raised rear axle of the lifting mechanism are rotatably connected to the front wheel and rear wheel on the left and right sides of the bottom, respectively. Both the raised front axle and raised rear axle are rotatably connected to a double-threaded rod. The two ends of the double-threaded rod are connected to the support shafts of the front wheel and the rear wheel respectively through threaded engagement. The double-threaded rod is rotated in a controlled manner and drives the front wheel and the rear wheel on the left and right sides to move synchronously in opposite directions or in opposite directions in the horizontal direction to adjust the wheel spacing. The film covering mechanism is fixedly connected to the bottom of the raised front axle, and the spraying mechanism is fixedly connected to the top and rear of the frame.

[0008] Furthermore, the frame, lifting mechanism, engine, coating mechanism, and spraying mechanism are combined through direct or indirect fixed connections, rotating connections, transmission connections, pipeline connections, and other means.

[0010] Preferably, an oil pump is connected to the right side of the oil cylinder, and a distributor is also installed on the top of the frame. The distributor is electrically or hydraulically connected to the oil pump and the lifting mechanism to adjust various data of the integrated machine.

[0011] Preferably, the mulching mechanism includes a front trenching disc fixedly connected to the bottom of the front side of the raised front axle, the front trenching disc being used to push the soil to both sides of the travel path before the mulching operation.

[0012] Preferably, the film coating mechanism further includes a film mounting rod rotatably connected to the bottom of the raised front axle, the film mounting rod being located on the rear side of the front trenching disc.

[0013] Preferably, the bottom of the raised front axle is rotatably connected to a windproof wheel and a clamping wheel on the rear side of the film hanging rod.

[0014] Preferably, the rear end of the raised front axle is rotatably connected to a film pressing wheel, and the rear bottom of the frame is fixedly connected to a rear upper soil plate, which is used to cover the soil on both sides towards the edge of the mulch film.

[0015] Preferably, the spraying mechanism includes a bucket fixedly connected to the top of the vehicle frame, a medicine tank fixedly connected to the top of the bucket, and a medicine pump fixedly installed on the front side of the bucket, with the medicine pump communicating with the medicine tank.

[0016] Preferably, a spray boom is fixedly installed on the rear side of the vehicle frame, and the spray boom is connected to the medicine tank through a hose for spraying operations.

[0017] Preferably, the height of the raised front axle and the raised rear axle is set to cover the arched canopy within 600mm in height, and by adjusting the bidirectional threaded rod, an adjustable wheel spacing of 1200mm to 1800mm is formed between the front wheels and between the rear wheels.

[0018] This utility model has the following beneficial effects: 1.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides a self-propelled arched greenhouse mulching and spraying integrated machine, which aims to solve the technical problem that existing agricultural machinery has a single function and a fixed chassis height and wheel track, making it unable to adapt to the operation requirements of arched greenhouses of different heights and different ridge spacing.

[0025] Please refer to Figure 1 and Figure 2 The self-propelled arched greenhouse mulching and spraying integrated machine includes a frame 1 and a lifting mechanism 7 fixedly connected to the bottom of the frame 1. The lifting mechanism 7 serves as the walking support component of the whole machine and can adapt to the operation of arched greenhouses at a certain height. An engine 2 is fixedly installed on the top of the frame 1, which provides power for the operation of the integrated machine. A mulching mechanism 8 for ground operation is installed on the front side of the bottom of the frame 1, and a spraying mechanism 9 for crop protection is installed on the top and rear side of the frame 1.

[0026] The lifting mechanism 7 includes a raised front axle 701 and a raised rear axle 702 spaced apart along the front-rear direction of the frame 1. The raised front axle 701 is located on the front side, and the raised rear axle 702 is located on the rear side. The chassis height of the raised front axle 701 and the raised rear axle 702 is designed to cover an arched canopy up to 600mm in height. Front wheels 704 are rotatably connected to the left and right sides of the bottom of the raised front axle 701, and rear wheels 705 are rotatably connected to the left and right sides of the bottom of the raised rear axle 702. The engine 2 drives the rear wheels 705 on the raised rear axle 702 to rotate through an internal transmission shaft system, thereby realizing the self-propelled movement of the entire machine. Both the raised front axle 701 and the raised rear axle 702 are rotatably connected to a double-threaded rod 703 inside. The two ends of the double-threaded rod 703 are connected to the support shafts of the front wheel 704 and the rear wheel 705 respectively through threaded engagement. When the bidirectional threaded rod 703 is rotated under control, it drives the front wheels 704 and rear wheels 705 on both sides to move synchronously in opposite directions or in the horizontal direction, thereby forming an adjustable wheel spacing of 1200mm to 1800mm between the front wheels 704 and the rear wheels 705 to meet the ridge width requirements of most crop planting plots. The top of the frame 1 is also fixedly equipped with a gearbox 3 and a hydraulic cylinder 6.

The distributor 5 is electrically or hydraulically connected to the oil pump 4 and the lifting mechanism 7, etc., to adjust various data of the integrated machine.

[0027] Please refer to Figure 1 , Figure 2 and Figure 4 The raised front axle 701 has a front trenching disc 805 fixedly connected to its front bottom. The front trenching disc 805 is constructed as a plow-shaped or disc-shaped structure capable of pushing soil piles on the travel path to both sides. A film-hanging rod 801 is rotatably connected to the bottom of the raised front axle 701.

The rear end of the raised front axle 701 is rotatably connected to the pressing roller 804. The pressing roller 804 is located behind the clamping rollers 803 to compact the released mulch film tightly onto the ground. The rear bottom of the frame 1 is fixedly connected to the rear upper soil plate 806. The rear upper soil plate 806 is located behind the pressing roller 804 and is used to cover the soil on both sides towards the edge of the mulch film to form soil pressure coverage.

[0028] Please refer to Figure 1 and Figure 2The spraying mechanism 9 includes a bucket 901 fixedly connected to the top of the frame 1. A medicine tank 902 for holding liquid medicine is fixedly connected to the top of the bucket 901. A medicine pump 903 is fixedly installed on the front side of the bucket 901. The medicine pump 903 is connected to the medicine tank 902 to provide fluid delivery power. A spray bar 904 is fixedly installed on the rear side of the frame 1.

The liquid medicine in the medicine tank 902 is delivered to the spray bar 904 through the hose under the action of the medicine pump 903 and sprayed at the rear of the integrated machine.

[0029] As a preferred embodiment, in order to optimize the power transmission layout of the self-propelled arched greenhouse mulching and spraying integrated machine and provide a compact installation space for the hydraulic system, the gearbox 3 is fixedly installed on the top of the frame 1 and located behind the engine 2. The gearbox 3 and the engine 2 are connected through a transmission component to transmit power. The oil cylinder 6 is fixedly installed on the top of the engine 2. The right side of the oil cylinder 6 is connected to the oil pump 4, and a fluid passage is formed between the oil pump 4 and the oil cylinder 6. The top of the frame 1 is also fixedly installed with a distributor 5. The distributor 5 is connected to the oil pump 4 and the lifting mechanism 7 through pipelines to serve as a control hub to adjust various hydraulic data during the operation of the integrated machine.

[0030] As another preferred embodiment, in order to ensure that the mulch film remains flat during the mulching process and is prevented from being blown away by the wind, the windproof wheel 802 and the clamping wheel 803 are rotatably connected to the rear side of the bottom of the raised front axle 701. The windproof wheel 802 and the clamping wheel 803 are arranged at intervals in the front-rear direction, and a clamping channel for the mulch film to pass through is formed between the windproof wheel 802 and the clamping wheel 803. Through the cooperation of the windproof wheel 802 and the clamping wheel 803, tension can be applied to the mulch film that passes through.

[0031] As another preferred embodiment, in order to improve the connection flexibility of the spraying mechanism 9 during operation and prevent mechanical vibration from causing the rigid pipeline to break, the spray bar 904 is connected to the medicine tank 902 through a hose. One end of the hose is connected to the outlet of the medicine tank 902 or the medicine pump 903, and the other end of the hose is connected to the inlet of the spray bar 904.

[0032] As another preferred embodiment, in order to adapt to the planting environment of different sizes of arched sheds and prevent damage to crops during operation, the chassis height of the raised front axle 701 and the raised rear axle 702 is configured to cover arched sheds with a height of up to 600mm. The thread length and stroke of the bidirectional threaded rod 703 inside the raised front axle 701 and the raised rear axle 702 are configured to allow an adjustable wheel spacing of 1200mm to 1800mm to be formed between the front wheels 704 and between the rear wheels 705.

[0033] Working principle: After the integrated machine is started, engine 2 provides power to the whole machine. Engine 2 transmits power to the raised rear axle 702 through gearbox 3, driving the rear wheel 705 to rotate, thereby realizing the self-movement of the whole machine. Oil pump 4 delivers energy from oil cylinder 6. The distributor 5 controls the various motion data of the whole machine. Before operation, according to the width requirements of the arch, the distributor 5 controls the rotation of the bidirectional threaded rod 703 inside the raised front axle 701 and raised rear axle 702. The bidirectional threaded rod 703 drives the front wheel 704 and the rear wheel 705 to move synchronously to the sides or the middle through threaded engagement, so that the wheel spacing is adjusted to the required range of 1200mm to 1800mm, ensuring that the integrated machine can accurately cross over the arch for operation. After the integrated machine starts moving, the mulching mechanism 8 and the spraying mechanism 9 start working simultaneously. The front trenching plate 805 first pushes the soil on the moving path of the integrated machine to both sides to create a flat ground for subsequent mulching. The mulch film roll is threaded onto the hanging rod 801 and begins to unfold. The unfolded mulch film passes through the clamping channel formed by the windproof wheel 802 and the clamping wheel 803 in sequence. The windproof wheel 802 and the clamping wheel 803 apply tension to the mulch film to ensure that the mulch film remains flat and is not blown away by the wind during the laying process. The pressing wheel 804 presses the mulch film tightly onto the ground. The rear upper soil plate 806 located at the tail of the integrated machine then pushes the soil on both sides back to cover the edge of the mulch film, forming an effective soil pressure cover to complete the mulching operation. Simultaneously, the spraying mechanism 9 begins operation. The pesticide solution contained in the pesticide tank 902 is transported through the hose to the spray boom 904 on the rear side of the frame 1 under the drive of the pesticide pump 903. The spray boom 904 sprays the crops or soil behind or simultaneously with the mulching operation, realizing the integrated function of mulching and pesticide spraying, which improves the overall efficiency of agricultural production. By increasing the chassis height of the front axle 701 and the rear axle 702, the whole machine can safely cross the arched shed with a height of up to 600mm during operation, effectively protecting the crops.
