Description

  The present invention relates to the field of rice transplanters, and further to an electric rice transplanter and its application.

  It is no exaggeration to say that agriculture is the basis of human survival and development, and provides people with the most basic living security. With the development of science and technology, agricultural production methods are constantly improved, and human power and livestock farming methods are being changed to mechanized production methods, greatly liberating production labor and improving production efficiency.

  In conventional agricultural machines, instead of conventional human-powered and livestock-driven power-driven methods, a fuel-powered source is used to drive agricultural machines to execute various agricultural production activities, so the power source is important for agricultural machines. Part. Rice transplanters are one of the important agricultural machines, and with the development of mechanical power, it is common to use a fuel machine as a motive power source for motive power of conventional agricultural machines. Being used for a long time, fuel machines provide many benefits and save much labor, but at the same time cause harmful effects of environmental pollution that has attracted attention.

Conventional fuel machines convert the thermal energy generated by the combustion of fuel, usually diesel or gasoline in the engine, into mechanical energy. As is well known, based on the principle of power generation, diesel or gasoline produces large amounts of pollutants in the combustion process, such as benzene in hydrocarbon (HC) emissions, toluene and xylene, nitrogen oxides (NO), carbon monoxide (CO) ), Sulfur dioxide (SO ₂ ), ozone (O ₃ ), etc. These contaminants not only pollute the environment but also directly affect human health. Furthermore, in the agricultural production process, both the operator and the power part are placed in an open environment and the distance between the power part and the person is relatively short, compared to a machine with a relatively enclosed space like a car While the direct damage to the body of the agricultural machine operator is much greater than other fuel machine operators, in terms of manufacturing costs and technical difficulties, the degree of exhaust gas purification of the agricultural machine is Much lower than cars. Therefore, environmental pollution is a major drawback existing in fuel machinery, and especially with the emphasis on environmental protection and environmentally friendly development expected today, such defects are becoming particularly prominent.

  On the other hand, although fuel mechanical power is already a fairly mature technology, the mechanical complexity of the fuel machine is high based on the basic working principle, it is difficult to reduce and various mechanical working parts in agricultural machines In combination with this, the entire agricultural machine will be larger, and it will be difficult to implement running and control.

And, the weight of the machine is definitely an important factor that affects the convenience of work, and it is necessary to spend a lot of physical strength.

  The development of agricultural machine products is inseparable from the development of other related technologies, but at the same time must be combined with the specific product requirements. For example, although the development of agricultural machinery power depends on the development of automotive power sources, agricultural machinery can not directly apply automotive power sources because work environments and application requirements are different. While rice transplanters are an important type of many agricultural machines, and have the various drawbacks described above, there are special requirements for power supplies because of their own special production work environment.

  The following description is for the purpose of disclosing the present invention so that those skilled in the art can practice the present invention. The preferred embodiments in the following description are merely illustrative, and other obvious variations can be envisaged by the person skilled in the art. The basic principles of the invention as defined in the following description may be applied to other embodiments, variants, modifications, equivalents and other technical solutions without departing from the spirit or scope of the invention.

Paddy rice planters are cultivation agricultural machines for planting rice seedlings in the paddy field, and save labor by working with machines instead of manual planting of the seedlings, effect of rice planting and planting quality The rice transplanter can be used for mechanization of rice cultivation to increase the planting capacity, achieve reasonable dense planting, and facilitate the mechanization of the subsequent work, and the subsequent management and harvesting can be easily performed by mechanical means.
Since almost half of the world's population uses rice as a staple food, and rice is an essential crop for humans, improvement and development of rice transplanters has important significance for agricultural production and human life.
As mentioned above, the rice planter has achieved a relatively complete technical level in terms of mechanical performance as a result of long-term development, and various types of rice planters with different functions, different types and different structures emerge one after another However, these improvements are generally based on fuel mechanical power.
As fuel-powered technology is mature and easy to apply, it has been developed based on fuel-powered in the field of rice transplanter, as it leads to safety and certainty of operation as an important part of agricultural machine is there.
However, as mentioned above, based on the working principle of the fuel machine and the corresponding mechanical structure, there are many disadvantages such as environmental pollution, damage to the body, complicated mechanical structure, large mass, poor operability, etc. However, these disadvantages are that the fuel machine itself can not be overcome, and therefore, to overcome the above disadvantages, starting from the power source of agricultural machinery, a substitute for the underlying fuel power, Problem must be solved.
According to an embodiment of the present invention, instead of providing a power source by burning fuel as in a conventional fuel machine, providing kinetic energy using electric energy as a power source to drive and operate a rice planter At the same time, by converting electrical energy into mechanical energy, it will not generate any harmful gases that cause environmental pollution, and it will also prevent the operator from absorbing harmful gases due to the close distance and damaging the body, It aims to provide an electric rice transplanter.

  The electric rice planter of the present invention uses electric energy as a motive power source, and the operation environment is usually a paddy field, so the waterproof performance of the electric motor system 10 is important for the electric rice planter. Water resistance is particularly important because the power supply 11, the power management unit 12 and the control unit 14 of the motorized system 10 in particular have a large amount of circuitry and integrated circuit components.

  7A-7B illustrate the circuit module 100 of the motorized system 10 according to one preferred embodiment of the present invention. The circuit module 100 includes a sealed box 110 that is capable of sealing the circuit members of the motorized system 10 in a waterproof and insulative manner.

  In one embodiment, an insulating layer 1101 is provided in the sealed box 110 to insulateably protect circuit members inside the sealed box 110. For example, the insulating layer 1101 is added to the inner surface of the box by spraying in the manufacturing process, or the insulating layer 1101 is laminated in the box. In particular, the sealed box 110 has a predetermined hardness and mechanical strength that can withstand a certain weight so that members such as the power supply 11 and the circuit board can be stably mounted inside.

  Furthermore, the circuit module 100 includes a waterproof connection part 120 installed in the sealed box 110 to electrically connect an external device and a circuit member in the sealed box 110 in a waterproof manner.

In one embodiment of the present invention, the circuit module 100 includes the power supply 11, the power management unit 12 and the control unit 14.
The power source 11, the power source management unit 12 and the control unit 14 are sealed in the sealed box 110, and when the rice transplanter works in the paddy field, the water content is the power source 11, the power source management unit 12 and the water source. Contamination of the control unit 14 prevents adverse effects on the operation of the circuit.
The power supply 11, the power management unit 12 and the control unit 14 are electrically connected to the display unit 13 and the drive unit 15 via the waterproof connection unit 120.
In one embodiment, in particular, the power supply 11 is the battery pack, the circuits of the power management unit 12 and the control unit 14 are integrated on a circuit board, and the battery pack is electrically connected to the circuit of the circuit board. Connected
The battery pack and the circuit board are mounted so as to be insulated and waterproof in the sealed box 110, and the circuit in the battery pack and the circuit board is, for example, the drive unit 15 and the display unit 13 by the waterproof connector 120. And other external members.

  More specifically, the waterproof connection 120 is provided with two sets of aviation connectors having different interfaces in order to connect different types of circuits.

  The circuit module 100 is installed at a predetermined height so that the circuit module 100 has excellent waterproof performance. For example, when the rice transplanter travels in a paddy field, the circuit module 100 has a predetermined height, so it does not contact the water surface of the paddy field, thus preventing water from entering the circuit module 100.

According to the preferred embodiment of the present invention, the circuit module 100 is installed below the spare part 323 of the rice transplant unit 32 so that the spare part 323 can shut off the circuit module 100.
Since the circuit module 100 leads to the operation of the circuit, waterproofing is important in any environment, and in the present embodiment of the present invention, the circuit module 100 is installed below the spare part 323. Therefore, in the case of rain or snow, the reserve unit 323 protects the circuit module 100 from rain or snow, and reduces the damage of the circuit module 100 due to rain or snow.
On the other hand, since the height of the spare part 323 can be adjusted as necessary, the height is set according to the necessity of the circuit module 100, and the water surface of the circuit module 100 is operated when the rice transplanter operates in the paddy field.

The display unit 13 has a waterproof effect apart from the water surface of the paddy field.

Furthermore, in one embodiment, the display unit 13 may be an electronic display screen that directly displays data such as voltage, current, temperature and SOC measurement of the power supply 11.
In another embodiment of the present invention, the display unit 13 is a touch control screen, and the display unit 13 displays data and has a touch operation function, and various controls by operating on the touch control screen. Can do the function.
That is, by installing the function of the operation member of the operation unit 34 on the display unit 13, the rice transplanter can be controlled not only by the mechanical manual control method but also by the electronic operation method.

The closed box 100 of the electric system 10 is installed at the front of the rice transplanter, and all of the closed box 100, the drive unit 15, the display unit 13 and the mechanical transmission system 20 have a predetermined height. In addition to having the positions matching with each other, the waterproof performance of the motorized system 10 and the mechanical transmission system is improved, and the operability is high.

Furthermore, the electric rice planter uses electric energy as driving energy, is clean, and the electric system 10 has a smaller mass than the conventional fuel driving system and has high energy storage property. Therefore, the mass of the whole rice transplanter is reduced to extend the operation time while facilitating the actual operation process.
For example, when the electric rice transplanter performs a bending operation, it is common for the operator to operate the handle portion 341 to lift the machine body and to steer using the traveling portion as a fulcrum. Due to the large mass, such operations are laborious and difficult to operate, whereas the electric rice transplanter of the present invention is easier to carry out when it operates like a curve because the mass is small. Can and save the strength of the operator.

  Furthermore, the working system 930 includes a wheel group 9311 for causing the rice transplanter to travel. The electric system 910 provides a power source for the wheel group 9311 to travel.

  Unlike the other types of rice transplanters, the electric rice transplanters can not only travel in the paddy field, but can also travel on a general road surface. Therefore, the electric rice transplanter can travel to the rice by itself, and does not need to be transported to the rice by a vehicle like other types of rice transplanters. That is, the electric system 910 can provide power in different traveling states of the electric rice transplanter.

  In particular, in one embodiment, the wheel group 9311 includes a group of front wheels 93111 and a group of rear wheels 93112. The front wheels 93111 of the first group are located at the front of the fuselage of the electric rice transplanter, and the rear wheels of the first group are located at the rear of the fuselage of the electric rice transplanter. The front wheels 93111 can be used for traveling and steering.

  In one embodiment of the present invention, the traveling unit 931 includes a float group 9312 including a center float and a side float. The center float 9312 and the side float are used for traveling of the rice transplanter at the time of paddy field work. The center float 9312 is installed at the middle and rear position of the rice transplanter, and the side floats 9313 are installed at both sides of the center float 9312.

  According to one embodiment of the present invention, the work system 930 includes a rice planting unit 932 for carrying out rice planting work. The center float and the side float are located below the rice transplant unit 932.

According to an embodiment of the present invention, the traveling unit 931 lifts and lowers the rice planting unit 932, the center float, and the side float of the rice transplanter so that the rice transplanter is suitable for different traveling and working conditions. including.
For example, when traveling on a general road surface, the raising and lowering mechanism raises the distance between the operation unit 933 and the center float and the side float from the road surface by setting the rice transplant unit 932 of the rice transplanter to the elevated state. To prevent the work system 930 or the center float and the side float from being disturbed by road surface objects, and to travel easily and quickly,
When carrying out the planting work in the paddy field, the raising and lowering mechanism brings the rice planting unit 932 and the center float and the side float close to the ground of the rice field by setting the rice planting unit 932 of the rice planter to the lowered position. As a result, the operation unit 933 becomes suitable for work, and the center float and the side float float on the paddy field and travel.

The traveling unit 931 includes a passenger portion 9314 for providing a passenger position and for the operator to ride the rice transplanter to operate the rice transplanter to advance in synchronization with the rice transplanter.
It should be noted that, compared to other types of rice transplanters, the electric rice transplanters provide a riding position and provide sufficient power, whereby the rice transplanters travel without the need for traction by the operator and the operator Does not run in paddy fields, and such a system has many advantages.
On the other hand, the traveling speed of the electric rice transplanter is not limited by the traveling speed of the operator, and the traveling speed of the rice transplanter can be greatly improved. Especially when traveling on a road surface, it is not transported by another tool. Also, it can travel at high speed, which greatly improves the working efficiency of the rice planting process, while in the case of other non-ride type rice transplanters, the operator needs to travel on the ground to provide traction. Because the operator's traveling speed affects the traveling speed of the rice transplanter,
On the other hand, the electric system 910 reduces the driving force required for the rice transplanter to reduce the mass of the entire rice transplanter, and provides more kinetic energy to the rice transplant unit 932 to reduce the rice transplanter. Because the electric rice planter uses electric energy as a power source, it does not generate a gas that contaminates the environment during traveling or work processes, and at the same time, it can damage the body. When combined with the high-speed rice transplanter, the operator does not travel in the field but travels to the passenger section 9314 when planting work, thereby further reducing the contamination of people by the field, and the working environment Improve.

  In addition, the drive unit 915 of the electric system is installed at a position below the passenger part 9314, whereby the structure of the rice plant is more rationally installed and the spatial position is utilized.
