Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, in particular to a self-propelled small arch shed composite building machine with a central power source. Background Art

[0002] Since most of the machines used to build small arch sheds were tractor-pulled, there was often a shortage of tractors and workers in the spring, and it was impossible to seize the right farming time. In addition, the speed of building small arch sheds was slow, which affected the operating efficiency of tractors and drivers, directly affected their operating income, and affected the enthusiasm of users. Therefore, it is necessary to develop a self-propelled small arch shed construction machine. After continuous testing and experiments, we finally designed and built a power mid-mounted small arch shed composite construction machine. Its main features are a power platform with high ground clearance. The engine, hydraulic device and operator are all located in the center of the vehicle body. A ditching and throwing rod arching and inserting rod device is hung on the front of the vehicle body, and a windproof film covering device is installed at the rear of the vehicle body. The front and rear frames are consistent in width to ensure that the shed film can be tightly covered with the built shed frame to prevent strong winds from blowing in and causing the shed to lift. The ditching plow is located on both sides of the front of the vehicle side frame, and the deep groove plowed is conducive to the smooth penetration of the shed pole into the soil. An external soil guide plate is installed on the outer side of the rear of the vehicle side frame, which can use more non-planting soil on the film covering to increase the wind resistance of the shed. Depending on the soil conditions, the two-wheel front-drive power platform will be used on hard soil, and the four-wheel drive platform is more suitable for sandy and soft soil plots to ensure that there is no slipping in the field and that the small arch shed is built more flat. Utility Model Content

[0003] The utility model provides a self-propelled small arch shed composite building machine with low dependence and higher working efficiency. To achieve the above purpose, the utility model provides the following technical solutions, including: three standard modules, the machine consists of a front ditching upper rod bending rod and insertion rod module, a central power module and a rear-mounted hydraulic film covering module. No tractor is needed for traction operation. The utility model is a self-propelled independent shed building machine, which is equipped with an automatic rod throwing device and a satellite navigation device. It does not require manual time-consuming and laborious care of the operation process, and only needs to be randomly supervised, which greatly saves manpower and energy. The driving force for the ditching grabbing rod bending rod and the insertion operation comes from the two front wheels. The sprocket drive chain on it automatically builds the shed according to the rod spacing and insertion depth. Since the rear wheel is turned, the shed operation is always in a straight line, and there will be no twisting and bending. The rear film covering module can select different film pressing methods according to the local wind conditions, including single film clamping wheel, three film clamping wheel and groove pressing method, which can adapt to different soil qualities, operation speeds and save the distance between sheds to meet the planting requirements of different economic crops. The whole machine can build a shed quickly, and only 1-2 people are needed to carry out quality supervision and supplementary work. There is no need to carry out heavy work of bending over, inserting poles, covering film and burying soil, thus saving a lot of labor and management costs and not delaying the farming season.

[0004] The utility model solves the following technical difficulties:

[0005] First of all, it gets rid of the dependence on tractors, no longer competing with them for work during the busy farming season, and improves the efficiency of the busy farming season. No longer relying on the creeper gear and high ground clearance function of the tractor, this machine has these two properties, can run at a constant speed and ensure the same quality of long-term operation. It gets rid of the dependence on the skilled technical level of the tractor driver and can work 24 hours a day. Different engines can be selected according to user requirements to save production costs. Whether it is manual or automatic throwing, it can ensure the consistent formation of the arch frame over a long distance and improve wind resistance. Not only galvanized metal rods can be used, but also nylon fiberglass rods of different diameters and hardness can be used. Adapt to three different film covering methods to ensure the same weight of soil covering on both sides, and strong wind resistance in various soil environments. The hydraulic lifting device can facilitate the conversion between operation and transportation, ensure timely lifting and lowering when encountering obstacles in the field, reduce damage to locomotives and field equipment and improve operation efficiency. The platform on the central power module can store a large number of shed poles and shed films, reduce the cost of transporting production materials back and forth in the field, and improve overall operation efficiency. After installing satellite navigation, the geographic data of sowing and transplanting can be shared, which can reduce damage to seedlings during greenhouse construction.

[0006] The beneficial effects of the utility model compared with the previous technology are as follows:

[0007] Through the above technical solutions, it can be known that compared with the prior art, the utility model discloses a self-propelled small arch shed composite construction machine with a central power, and the self-propelled power platform completely gets rid of the dependence on the tractor, so that the small arch shed construction work can be completed in a short time with high quality, and only a small number of people are needed to supervise the operation throughout the process, without using a large amount of labor for heavy field work, especially continuous operation in the wind. The whole machine does not need to adjust the technical parameters frequently during use, provides a high-quality lightweight operation method, greatly improves production efficiency, reduces management input, and makes cash crops more profitable.

[0008] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] Please refer to the attached Figure 1 , a self-propelled small arch shed composite building machine with a central power is disclosed in the utility model. It includes: a front ditching, throwing, arching and inserting rod module ①; a central driving module ②, and a rear-mounted hydraulic film covering and soil pressing module ③. The two modules ① and ③ are fixed on the front and rear beam brackets of ②, and are equipped with hydraulic devices that move up and down. During transportation, ① and ③ are hydraulically raised, and the four wheels of ② are used to transfer plots and travel on the road. During field operations, ① and ③ are lowered by the hydraulic system, and the rod insertion operation starts after the clutch of ① is engaged. The force arm of the film covering device ③ is pressed down by the hydraulic system to carry out soil covering and film covering operations.

[0013] When the user only needs to insert the pole, use the hydraulic system to raise ③, and only use the function of the front module to build a small arch shed frame. Then, after irrigation and spraying, when film covering is required, ① can be raised and ③ can be lowered to cover the film independently. For repair work in the case of film leakage caused by wind damage, at this time, ① can be raised and ③ can be lowered to cover the film again. The same is true for replacing insect nets.

[0014] In order to further optimize the above technical solution, see Figure 2 First, use a furrowing plow① to draw a 20-30 cm deep groove in the soil, remove solid soil or stones, and provide suitable soil space for inserting poles. The automatic pole-lifting device sorts and grabs the long straight pole②, rotates to the pole-throwing fence and is blocked, and the long straight pole automatically falls to the waiting position in the pole holder③, and the manipulator④ rotates to the right position and automatically grabs the shed pole. The manipulator can have two configurations, one is a single manipulator and counterweight, and the second is a symmetrical double manipulator, which can provide different speeds of pole grabbing capabilities. When the system starts to work formally, first turn on the clutch⑤, and the manipulator④ can start to rotate the sprocket on the ground wheel to start grabbing the pole.

[0015] In order to further optimize the above technical solution, see Figure 2The engine / motor⑥ of the center power module is located behind the front wheel of the force frame, and drives the hydraulic pump. The oil tank or battery⑦ is located in front of the rear wheel at the rear of the frame, which can provide 50-50% balance weight for the four wheels of the center module to prevent deviation on loose soil. The steering active wheel is located on the rear axle, providing four-wheel drive on poor soil and hillsides, and the steering wheel is still located on the rear axle.

[0016] In order to further optimize the above technical solution, see Figure 2 The central power module has a large platform⑧, which can provide sufficient space for the storage and transportation of shed poles and shed film, so as to ensure the material preparation for long-term and long-distance operations in the field without the need for multiple refilling and consuming services. The operator's drive device⑨ is located on the left side of the frame, which conforms to driving and working habits and is convenient for getting on and off the vehicle. It can be operated in standing or sitting positions. It has a cruise control function and can add automatic satellite navigation function.

[0017] In order to further optimize the above technical solution, see Figure 2 The film covering module is specially designed to resist wind and can continue to work on windy days. The film rolling frame ⑩ pulls out the film, which is naturally unfolded and clamped by the three sets of film clamping wheels 11 on each side arm. The film falls to the ground along the shed pole inserted into the soil by the manipulator ④. The special film pressing wheel at the bottom fits it to the ground, and then the soil is covered tightly by the notched rake blade 12. The hydraulic cylinders 13 on both sides of the arm can provide a downward pressure function, so that the rake blade can go deep into the soil layer to grab more soil. If it is a no-till land, if the amount of soil taken is insufficient, the metal counterweight on the counterweight frame 14 can be used to provide additional downward pressure, and the rake blade can cut more soil for covering and pressing the film.

[0018] In order to further optimize the above technical solution, see Figure 2 The film covering module can use a single film clamping wheel for film covering in non-strong wind areas, simplifying the structure and saving investment. In areas with strong winds and fine dust, since the film covering soil is likely to be blown away, we also provide a structure that cuts grooves and presses the film into deep grooves to ensure that the greenhouse film is not pulled away by the wind. This technical solution can provide a film covering mechanism for different conditions, so the utility model can cover multiple technical solutions.
