Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a paddy field machine. Background Technology

[0002] In existing technologies, the furrow openers for side-deep fertilization are all mounted on floating platforms. However, these platforms have the function of conforming to the shape of the ground and controlling the lifting and lowering of the rear suspension. Installing the furrow opener will affect the conforming function of the floating platform. Furthermore, the furrow opener's depth is not adjustable, affecting the fertilization effect and making it prone to damage during transportation and operation. Therefore, it is necessary to provide a paddy field machine to overcome the aforementioned shortcomings. Summary of the Invention

[0031] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0032] See Figure 1 This invention provides a paddy field machine, comprising: a main shaft 1, a crossbeam 2, a first connecting rod 3, a furrow opener 4, a soil covering plate 5, and a floating hull 6. The furrow opener 4 is located at the front end of the crossbeam 2, and the floating hull 6 is located below the crossbeam 2. The main shaft 1 and the crossbeam 2 are arranged parallel to each other, with the main shaft 1 located behind the crossbeam 2. The main shaft 1 includes a rocker arm 11 and a control lever 12. The rocker arm 11 and the control lever 12 are fixed to the main shaft 1, and pulling the control lever 12 up and down can cause the rocker arm 11 to swing.

[0033] See Figure 2 One end of the first connecting rod 3 is connected to the rocker arm 11, and the other end is connected to the trencher 4. The first connecting rod 3 is rotatably connected to the crossbeam 2. The rocker arm 11 swings, causing the first connecting rod 3 to rotate, thereby causing the trencher 4 to adjust the trenching depth up and down. In this embodiment, the front end of the crossbeam 2 is also provided with a fixing plate 21, and one end of the third connecting rod 3 is rotatably connected to the fixing plate 21. See also Figure 3 The front end of the rocker arm 11 is provided with a strip hole 111, and the first connecting rod 3 includes a connecting pin 32, which is located in the strip hole 111.

[0034] This embodiment also includes a second connecting rod 31. The second connecting rod 31 is arranged parallel to the first connecting rod 3, and is positioned above the first connecting rod 3. One end of the second connecting rod 31 is rotatably connected to the fixing plate 21, and the other end is connected to the trencher 4. Adding the second connecting rod 31 creates a four-bar linkage structure, resulting in better stability. In one embodiment of the present invention, the trencher 4, the first connecting rod 3, and the second connecting rod 31 are fixed.

[0035] join Figure 3 To enable the trencher 4 to avoid obstacles, a first connecting member 33 is also provided. The front ends of the first connecting rod 3 and the second connecting rod 31 are rotatably connected to the first connecting member 33. The trencher 4 is rotatably connected to the first connecting member 33. The trencher 4 includes a first rotating shaft 41, which passes sequentially through the first connecting member 33, the first connecting rod 3, and the trencher 4. The trencher 4 can rotate around the first rotating shaft 41. See also Figure 4 The first rotating shaft 41 is fitted with a first return spring 411, which is a torsion spring in this embodiment.

[0036] When the paddy field machine is working, the furrow opener 4 encounters obstacles such as stones, experiencing backward resistance. The bottom of the furrow opener 4 rotates backward to clear the obstacle. The first return spring 411 is used to return the furrow opener 4 to its initial position after clearing the obstacle. See also Figure 5The bottom of the first connecting member 33 is also provided with a protrusion 332 that protrudes laterally toward one side of the trencher 4. The protrusion 332 is located at the rear end of the top of the trencher 4 and is used to limit the rotation of the trencher 4 to prevent it from tilting excessively under the action of the first return spring 411. The trencher 4 also includes an adjustment hole 45 arranged around the first rotating shaft 41 for adjusting the preload of the torsion spring.

[0037] See Figure 4 The first connecting member 33 also includes a first positioning hole 331. The trencher 4 is also provided with a second positioning hole 43 and a third positioning hole 44. The trencher 4 also includes a positioning pin 42. The first positioning hole 331 and the second positioning hole 43 are located above the first rotating shaft 41, and the third positioning hole 44 is located below the first rotating shaft 41. If the soil is too hard, the positioning pin 42 is inserted into the first positioning hole 331 and the second positioning hole 43 to fix the trencher 4 and the first connecting member 33, allowing the trencher 4 to trench normally. Otherwise, the positioning pin 42 is placed in the third positioning hole 44.

[0038] See Figure 4 The paddy field machine is also equipped with a reset assembly 24, which includes a limiting part 241 located above the rocker arm 11 and a second reset spring 243. Because the bottom of the ditch opener 4 is lower than the bottom of the pontoon 6, when the paddy field machine is parked on concrete, the ditch opener 4 will bear part of the machine's weight, which can easily lead to damage. By setting up the reset assembly 24, the ditch opener 4 will rise upwards under the support of the concrete ground, preventing damage. The ditch opener 4, through the first connecting rod 3, drives the front end of the rocker arm 11 to rotate downwards.

[0039] When working in paddy fields, the second return spring 243 lifts the rocker arm 11 upwards, and the first connecting rod 3 adjusts the ditch opener 4 back to the initial ditching depth, achieving normal ditching. A limiting part 241 is positioned above the rocker arm 11 to restrict its position, preventing excessive upward rotation due to the action of the second return spring 243. In this embodiment, a fixing shaft 242 is also provided for fixing the second return spring 243, which is a torsion spring.

[0040] See Figure 1 and Figure 2 The main shaft 1 is also equipped with a first adjusting rod 13, and the crossbeam 2 is also equipped with a second adjusting rod 22. A connecting seat 61 is provided on the top of the floating vessel 6. A third adjusting rod 14 is provided between the first adjusting rod 13 and the connecting seat 61, and a fourth adjusting rod 23 is provided between the second adjusting rod 22 and the connecting seat 61. One end of the first adjusting rod 13 is fixed to the main shaft 1, and the other end is rotatably connected to the third adjusting rod 14. One end of the second adjusting rod 22 is fixed to the crossbeam 2, and the other end is rotatably connected to the fourth adjusting rod 23.

[0041] The third adjusting rod 14 and the fourth adjusting rod 23 are both rotatably connected to the connecting seat 61. Pulling the control rod 12 up or down drives the first adjusting rod 13 to rotate, which in turn drives the floating boat 6 to rise and fall through the linkage mechanism of the four adjusting rods. While the floating boat 6 rises and falls, the trench opener 4 adjusts its height synchronously, and the floating boat 6 and the trench opener 4 are adjusted in a coordinated manner.

[0042] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments described above without departing from the spirit and scope of the invention. Therefore, it is intended that this invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
