Description

Technical Field

[0001] The utility model relates to the technical field of rice transplanters, and more particularly to a rice transplanter and a flywheel protection component thereof. Background Art

[0002] In the power system of existing rice transplanters, the power output of the engine is transmitted to the gearbox through a flywheel (pulley) transmission assembly. Part of the power reaching the gearbox is transmitted to the transplanting box for rice planting, and part is transmitted to the wheels for moving and backward operations. The flywheel transmission assembly generally transmits power through two pulleys and a belt. It is usually located on the outside of the rice transplanter. When the rice transplanter is operating in the field, mud and water are easily splashed onto the pulleys, causing the pulleys to slip. Therefore, a protective cover is fixed on the outside of the flywheel transmission assembly to protect the flywheel transmission assembly.

[0003] For example, a Chinese patent document (publication number: CN 301291028 S) provides a rice transplanter belt cover wheel, but it cannot adapt to the flywheels of various engines on the existing market. At the same time, when the engine is working, its body will produce large vibrations, causing the connection between the cover wheel and the engine to fail.

[0004] For the above problems, relevant technologies do not provide effective solutions. Utility Model Content

[0006] Furthermore, the second plate is rectangular, and two adjustment holes are formed on the second plate, and the two adjustment holes are diagonally arranged on the second plate.

[0007] Furthermore, the connecting support plate is formed with a connecting groove, and the connecting groove is waist-shaped.

[0008] Furthermore, an avoidance recess is formed on the outer edge of the first connecting portion, and the avoidance recess is used to avoid the driving shaft of the flywheel assembly.

[0009] Furthermore, a plurality of connection holes are formed in the first connection portion along the edge of the avoidance recess for synchronous connection with the engine housing.

[0010] To solve the above problems, some embodiments of the present application also provide a rice transplanter, comprising a flywheel assembly, a gearbox, an engine and a rice transplanter flywheel protection assembly of any of the above schemes; the engine transmits power to the gearbox through the flywheel assembly, and the connecting support plate and the second plate are both parallel to the radial surface of the flywheel assembly.

[0011] Furthermore, the flywheel assembly includes a driving shaft and a driven shaft, and the main protective plate is formed with two protective protrusions, which protrude toward the side away from the flywheel assembly, and the two protective protrusions are used to respectively accommodate the ends of the driving shaft and the driven shaft.

[0012] Furthermore, the mounting frame also includes a muffler bracket mounting plate, which is connected to the first connecting portion and perpendicular to the first connecting portion; a notch is formed at the bottom of the flywheel guard so that the muffler bracket mounting plate extends from the notch.

At the same time, since the flywheel guard is connected to the gearbox and the engine respectively through the connecting support plate and the mounting frame, and the specific structures of the connecting support plate and the second connecting part are strictly limited, the installation flexibility of the flywheel guard is greater. The user can adjust the front and rear position of the flywheel guard by adding or reducing the number of gaskets on the connecting support plate and the mounting frame according to actual conditions, so as to fully reserve a safe distance between the flywheel guard and the flywheel input shaft and output shaft.

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to having a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientations or positional relationships, some of the above terms may also be used to indicate other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in certain circumstances. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0032] This embodiment provides a rice transplanter flywheel protection component, such as Figure 1 As shown, the flywheel guard 100 and the mounting frame 200 are included. The flywheel guard 100 can protect the flywheel assembly 300 and prevent the flywheel assembly 300 from being disturbed by soil flying in the field when the flywheel assembly 300 is working.

[0033] Specifically, this embodiment also provides a rice transplanter, such as Figure 2 As shown, the flywheel assembly 300, the engine 400, the gearbox 500 and the flywheel protection assembly are included. The engine 400 transmits power to the gearbox 500 through the flywheel assembly 300.

[0034] like Figures 1 to 3 As shown, the flywheel guard 100 is mounted on the outside of the flywheel assembly 300 to cover the flywheel assembly 300. The flywheel guard 100 is formed with a main guard plate 110. The main guard plate 110 is opposite to the radial surface of the flywheel assembly 300 and is substantially parallel to the radial surface of the flywheel assembly 300. A connecting support plate 120 is connected to the side of the main guard plate 110. The connecting support plate 120 extends parallel to the main guard plate 110 of the flywheel guard 100. The flywheel guard 100 is connected to the gearbox 500 via the connecting support plate 120.

[0035] like Figure 4 As shown, the mounting bracket 200 includes a first connecting portion 210 and a second connecting portion 220 . The first connecting portion 210 is a special-shaped plate for connecting to the engine 400 housing.

[0036] It is worth noting that the "special shape" here refers to the irregular board shape that is different from the regular shape.

[0037] like Figure 4 As shown, the second connection part 220 includes a first plate 221 and a second plate 222 perpendicular to each other. The second connection part 220 is L-shaped. The first plate 221 is connected to the first connection part 210 so that the second plate 222 protrudes relative to the first connection part 210.

[0038] Among them, Figure 4 As shown, the second plate 222 is attached to the inner sidewall of the main protective plate 110. The second plate 222 is formed with a plurality of adjustment holes 222a for connection to the flywheel guard 100. Specifically, the main protective plate 110 is provided with corresponding mating holes 111 for mating with the adjustment holes 222a. In actual use, the flywheel guard 100 is secured to the mounting bracket 200 using only one of the adjustment holes 222a.

[0039] Specifically, the connecting support plate 120 and the second plate 222 are parallel to the radial surface of the flywheel assembly 300 .

[0040] In this way, the connecting support plate 120 can not only provide support force to the flywheel guard 100 through the second plate 222, but also share part of the vibration force transmitted to the flywheel guard 100 by the engine 400, thereby avoiding fatigue damage to the connection caused by the direct connection between the flywheel guard 100 and the engine 400. At the same time, since the flywheel guard 100 is connected to the gearbox 500 and the engine 400 respectively through the connecting support plate 120 and the mounting frame 200, and the specific structures of the connecting support plate 120 and the second connecting portion 220 are strictly limited, the installation of the flywheel guard 100 is flexible. More flexible, in detail, the user can adjust the front and rear positions of the flywheel guard 100 by increasing or decreasing the number of gaskets on the connecting support plate 120 and the mounting frame 200 according to actual conditions, so as to fully reserve a safe distance between the flywheel guard 100 and the flywheel input shaft and output shaft. The user can also select different adjustment holes 222a on the mounting frame 200 as needed to adjust the upper and lower positions of the flywheel guard 100, thereby ensuring that the flywheel guard 100 is installed in the most appropriate position, further preventing damage to the flywheel guard 100, and adapting to the flywheel assembly 300 of different types of rice transplanters on the market.

[0041] The flywheel guard 100 in the related art is not flexible during installation, which will cause the installation position of the flywheel guard 100 to be offset, and the safety distance between the flywheel guard 100 and the input shaft of the gearbox 500 will become smaller or even disappear. The input shaft of the gearbox 500 in the working state will continuously wear the flywheel guard 100, thereby damaging the flywheel guard 100.

[0042] As an alternative, Figure 4As shown, the second plate 222 is rectangular, further increasing the contact area with the flywheel shield 100 . The second plate 222 is formed with two adjustment holes 222 a , which are diagonally arranged on the second plate 222 .

[0043] As another optional solution, the number of the connecting holes 212 on the second plate 222 may also be 3 or 4.

[0044] Preferably, Figure 3 As shown, the connecting support plate 120 is formed with a connecting groove 121 , which is waist-shaped, further increasing the adjustability of the connection of the flywheel shield 100 .

[0045] Specifically, if Figure 4 As shown, the outer edge of the first connecting portion 210 is formed with an avoidance recess 211, which is used to avoid the driving shaft 310 of the flywheel assembly 300. The outer side of the avoidance recess 211 cooperates with the driving shaft 310, and the avoidance recess 211 surrounds a portion of the outer circumference of the driving shaft 310.

[0046] More specifically, Figure 4 As shown, a plurality of connection holes 212 are formed in the first connection portion 210 along the edge of the avoidance recess 211 for synchronous connection with the engine 400. Since the first connection portion 210 is in close contact with the engine 400, the provision of multiple connection holes 212 helps to increase the stability of the connection of the mounting bracket 200.

[0047] Preferably, Figure 4 As shown, the second connecting portion 220 is formed with three connecting holes 212. Specifically, the angle between the three connecting holes 212 is 45 degrees, with the center of the driving shaft 310 as the vertex. This design ensures that the forces between the connecting holes 212 are balanced.

[0048] Further, such as Figure 2 As shown, the flywheel assembly 300 includes a driving shaft 310 and a driven shaft 320. The main protective plate 110 is formed with two protective protrusions 140. The protective protrusions 140 protrude toward the side away from the flywheel assembly 300. The two protective protrusions 140 are used to respectively accommodate the ends of the driving shaft 310 and the driven shaft 320. The area outside the protective protrusions 140 of the main protective plate 110 can provide space for other components of the rice transplanter, such as a muffler bracket.

[0049] Specifically, the driving shaft 310 of the flywheel assembly 300 is the power output shaft of the engine 400 , and the driven shaft 320 of the flywheel assembly 300 is the power input shaft of the gearbox 500 .

[0050] Specifically, such as Figure 4 、 5As shown, the mounting frame 200 also includes a muffler bracket mounting plate 230, which is connected to the first connecting portion 210 and is perpendicular to the first connecting portion 210; a notch 130 is formed at the bottom of the flywheel shield 100 so that the muffler bracket mounting plate 230 extends from the notch 130.

[0051] The flywheel protection assembly of the present application allows the user to flexibly adjust the relative position of the flywheel guard 100 on the engine 400 through the cooperation of the flywheel guard 100 and the mounting frame 200. The flywheel guard 100 can be adapted to a variety of rice transplanters on the market, and the mounting frame 200 can reduce the mechanical damage to the flywheel guard 100 caused by the vibration of the engine 400, thereby avoiding damage to the flywheel guard 100 and extending its service life.

[0052] In this application, the terms "installed," "disposed," "provided with," "connected," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0053] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
