Description

Technical Field

[0001] The present invention relates to a three - section folding roll press, and more specifically, to a three - section folding roll press. Background Art

[0002] At present, the tillage methods for farmland include rotary tillage and ploughing. Rotary tillage uses the rotary blades on the rotary tiller to break up the soil and carry out a certain degree of mixing; ploughing uses the ploughshare to turn up the farmland soil, and then uses a harrow to crush and mix the turned - up soil. Rotary tillage has a good effect on crushing the farmland soil and can carry out a certain degree of mixing of the soil, but it cannot bury the organic matter (fallen leaves, straw, etc.) on the ground surface deep underground and cannot fully exert the fertilizer - increasing effect of the organic matter on the farmland. Compared with rotary tillage, ploughing has two steps: turning up the soil and crushing the soil. Although the working efficiency is low, it can turn the deep soil of the farmland to the top and bury the surface soil together with the organic matter 30 cm underground, which is beneficial to the anaerobic fermentation of the organic matter, has a good fertilizer - increasing effect on the soil, and is beneficial to improving the soil. Therefore, the ploughing operation method is still retained in many areas.

[0003] In the case of soil compaction, if the ploughing operation method is adopted, there will be a large number of compacted soil clods in the turned - up soil, which are not easy to carry out harrowing operations and need to carry out crushing operations on the compacted soil clods. At this time, a roll press is required. For large farms, the existing small roll presses can no longer meet the requirements, and roll presses with a larger working width need to be developed.

Detailed implementation manners

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] As Figures 1 to 6 shown, the front view, right view, left view, right view, top view and bottom view of the three-section folding roller press of the present invention are respectively given, Figure 7 and Figure 8 the perspective views thereof are both given, Figure 9 , Figure 10 and Figure 11 the partial enlarged views of area A, area B and area C are respectively given. The three-section folding roller press of the present invention shown is composed of a traction frame 1, a front roller mechanism 2 and two side roller mechanisms 3. The front roller mechanism 2 is connected to the traction frame 1, and the two side roller mechanisms 3 are hinged to both ends of the front roller mechanism 2. The traction frame 1 is used to be connected to a traction machine so as to drive the front roller mechanism 2 and the side roller mechanism 3 to move under the dragging action of the traction machine. When the side roller mechanism 3 is unfolded, large-width rolling of the field can be realized. When the side roller mechanism 3 is folded, it can be dragged to travel on the road, so as to facilitate the transfer and transportation of the roller press.

[0015] The front roller mechanism 2 shown is composed of a front roller support 4, a front roller 5 and a front transport wheel mechanism 8. The front roller support 4 is rectangular, and both ends of the front roller 5 are rotatably arranged at both ends of the front roller support 4 so that the front roller 5 can freely rotate on the front roller support 4. There are two front transport wheel mechanisms 8, and the front wheel transport mechanism 8 is arranged at the rear of the front roller support 4 and is used to support the front roller support 4 during the transportation of the roller press. During rolling, the front transport wheel mechanism 8 folds upward so that the front roller 5 contacts the ground.

[0016] The side roller mechanism 3 shown is composed of a side roller 7, a side roller bracket 6, and a rear transport wheel mechanism 9. The side roller bracket 6 is also rectangular. Both ends of the side roller 7 are rotatably arranged on both sides of the side roller bracket 6, enabling the side roller 7 to rotate freely on the side roller bracket 6. The rear transport wheel mechanism 9 is arranged at the rear end of the side roller bracket 6 and can rotate and lift on the side roller bracket 6. When the rear transport wheel mechanism 9 rotates and rises on the side roller bracket 6, the side roller 7 contacts the ground, and at this time, the side roller 7 can roll the ground. When the rear transport wheel mechanism 9 rotates downward to lift the side roller bracket 6, it is used for the transfer and transportation of the roller press.

[0017] To achieve the connection between the side roller mechanism 3 and the front roller mechanism 2, horizontal crossbeams 10 facing backward are fixed at both ends on the rear side of the shown front roller bracket 4. The front end of the side roller bracket 6 is hinged to the outer end of the crossbeam 10. In this way, the side roller bracket 6 can rotate relative to the front roller bracket 4. A rear pin shaft 11 is fixed on the shown crossbeam 10, and the length direction of the rear pin shaft 11 is the same as that of the crossbeam 10, that is, horizontal and facing backward. Two front perforated ear plates 12 are fixed on both sides of the front part of the front roller bracket 4, and the hole direction on the front perforated ear plates 12 is perpendicular to the length direction of the front roller 5.

[0018] A first split pin plate 13 and a second split pin plate 14 are arranged on the outer side of the front end of the side roller bracket 6. When the side roller bracket 6 rotates to a position where the side roller 7 is parallel to the front roller 5, the openings on the first split pin plate 13 and the second split pin plate 14 are both caught on the rear pin shaft 11. The shown first split pin plate 13 is fixed on the side roller bracket 6, and the opening on the first split pin plate 13 faces horizontally. The opening on the second split pin plate 14 faces downward. The middle part of the second split pin plate 14 is hinged to the side roller bracket 6. The front end of the second split pin plate 14 is open, and the rear end of the second split pin plate 14 is connected to the side roller bracket 6 through a pin plate oil cylinder 15, that is, both ends of the pin plate oil cylinder 15 are respectively hinged to the rear end of the second split pin plate 14 and the side roller bracket 6.

[0019] In this way, when the telescopic rod of the pin plate oil cylinder 15 retracts, the front end of the second split pin plate 14 can be lifted, the side roller bracket 6 rotates, and the opening on the first split pin plate 13 is caught on the rear pin shaft 11. At this time, the opening on the second split pin plate 14 is located above the rear pin shaft 11. When the telescopic rod of the pin plate oil cylinder 15 extends, the opening on the second split pin plate 14 is caught on the rear pin shaft 11. It can be seen that by catching the opening on the first split pin plate 13 on the rear pin shaft 11, the limit of the up and down displacement of the side roller bracket 6 can be achieved; by catching the opening on the second split pin plate 14 on the rear pin shaft 11, the limit of the side roller bracket 6 in the length direction of the front roller 5 can be achieved, avoiding the movement of the side roller bracket 6 in the length direction of the front roller 5.

[0020] On the outer side of the shown side roller support 6, a connecting tie rod 16 is provided. The connecting tie rod 16 is hinged to the side roller support 6. The connecting tie rod 16 is connected to the side roller support 6 through a tie rod oil cylinder 17, that is, the two ends of the tie rod oil cylinder 17 are respectively hinged to the connecting tie rod 16 and the side roller support 6. When the tie rod oil cylinder 17 drives it to turn up and fold, the width of the side roller support 6 will not increase. A belt port joint 18 is provided at the front end of the side roller support 6. When the tie rod oil cylinder 17 drives the connecting tie rod 16 to a horizontal state and the side roller support 6 rotates to a state where the side roller 7 and the front roller 5 are horizontal, at this time, the belt port joint 18 on the connecting tie rod 16 will snap into the two front belt hole ear plates 12. At this time, by inserting a pin into the two front belt hole ear plates 12 and the belt port joint 18, the connection between the front end of the side roller support 6 and the front side of the front roller support 4 can be realized.

[0021] It can be seen that through the first belt port pin plate 13 and the second belt port pin plate 14, the connection between the side roller support 6 and the rear part of the front roller support 4 can be realized, and the limit of the up and down displacement and the displacement along the length direction of the front roller 5 of the side roller support 6 can be realized; through the connection between the belt port joint 18 on the connecting tie rod 16 and the two front belt hole ear plates 12, the connection between the side roller support 6 and the front part of the front roller support 4 can be realized. In this way, the side roller 7 and the front roller 5 are on the same straight line to realize the rolling of the field.

[0022] As Figure 10 shown, the shown front transport wheel mechanism 8 is composed of a front transport wheel 22, a front transport wheel support rod 23 and a front transport wheel oil cylinder 24. The front transport wheel 22 is arranged at the rear end of the front transport wheel support rod 23. The front end of the front transport wheel support rod 23 is hinged to the front roller support 4. The front transport wheel support rod 23 is connected to the front roller support 4 through a front transport wheel oil cylinder 24, that is, the two ends of the front transport wheel oil cylinder 24 are respectively hinged to the front transport wheel support rod 23 and the front roller support 4. In this way, when the front transport wheel oil cylinder 24 drives the front transport wheel 22 to fold up, the front roller 5 is in contact with the ground, and the front roller 5 can be used to roll the field; when the front transport wheel oil cylinder 24 drives the front transport wheel 22 to contact the ground and the front roller 5 leaves the ground, the transfer and transportation of the front roller mechanism 22 are realized by the grounding and rotation of the front transport wheel 22.

[0023] As Figure 11 shown, the shown rear transport wheel mechanism 9 is composed of a rear transport wheel 25, a rear transport wheel support rod 26, a rear part square tube 27, a rear transport wheel lifting oil cylinder 28 and a rear transport wheel rotating oil cylinder 32. The two ends of the rear part square tube 27 are hinged to the rear end of the side roller support 6, and the rear part square tube 27 is in a horizontal state. The rear transport wheel 25 is arranged at the lower end of the rear transport wheel support rod 26. The upper end of the rear transport wheel support rod 26 is rotatably connected to the rear part square tube 27.

[0024] The rear transport wheel lifting oil cylinder 28 drives the rear square pipe 27 to rotate through the second connecting rod 29, so as to realize the lifting and lowering of the rear transport wheel 25. The second connecting rod 29 is composed of three sections hinged to each other. The front end of the second connecting rod 29 is hinged to the side roller bracket 6, the rear end of the second connecting rod 29 is fixedly connected to the rear square pipe 27, and both ends of the rear transport wheel lifting oil cylinder 28 are respectively hinged to the side roller bracket 6 and the second connecting rod 29. When the lifting oil cylinder 28 extends to drive the rear transport wheel 25 to lower to the lowest position, the front side of the rear square pipe 27 is in contact and limited with the rear end face of the side roller bracket 6. At this time, the side roller 7 is lifted, and the rear transport wheel 25 contacts the ground, so as to realize the transfer and transportation of the side roller 7. When the rear transport wheel lifting oil cylinder 28 drives the rear transport wheel 25 to lift, the side roller 7 contacts the ground, and the rolling of the field can be realized.

[0025] In order to realize that the side roller mechanism 3 can rotate relative to the front roller mechanism 2 to realize the unfolding and folding of the side roller mechanism 3, it is necessary for the side roller 7 to rotate in the horizontal plane and rotate to an angle with a certain angle to the length direction of the side roller 7 to realize the rotation of the side roller mechanism 3. The rotation of the rear transport wheel 25 in the horizontal plane is realized by the rear transport wheel rotating oil cylinder 32. As shown, a movable plate 30 is fixed on the rear transport wheel support rod 26, and a fixed plate 31 fixedly connected thereto is arranged below the rear square pipe 27. Both ends of the rear transport wheel rotating oil cylinder 32 are respectively hinged to both ends of the movable plate 30 and the fixed plate 31. In this way, by the telescopic movement of the rear transport wheel rotating oil cylinder 32, the rear transport wheel 25 can be driven to rotate in the horizontal plane.

[0026] When the rotation direction of the rear transport wheel 25 is consistent with the length direction of the side roller 7, and at this time the side roller mechanism 3 is in a folded state, the transportation and transfer of the roller press can be realized; when the rear transport wheel 25 rotates to a certain angle with the side roller 7, the side roller mechanism 3 can rotate relative to the front roller mechanism 2, which is convenient for realizing the unfolding of the side roller mechanism 3.

[0027] As Figure 7 shown, a traction pin hole 19 is opened at the front end of the traction frame 1, and the connection with the traction machinery is realized through the traction pin hole 19. The rear end of the traction frame 1 is hinged to the center of the front part of the front roller bracket 4, and the lifting of the traction frame 1 is realized through the traction frame oil cylinder 20 and the first connecting rod 21. The lower end of the first connecting rod 21 is hinged to the front roller bracket 4, and both ends of the traction frame oil cylinder 20 are respectively hinged to the traction frame 1 and the upper end of the first connecting rod 21.

[0028] To sum up, after the two side roller mechanisms 3 are unfolded, the two side rollers 7 are parallel to the front roller 5, and a larger width can be obtained, which is convenient for efficiently rolling the field. When the two side roller mechanisms 3 are folded up, their width is only the width of the front roller mechanism 2, which can meet the requirements for driving on the road and is convenient for the transfer and transportation of the roller press.
