Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of silage harvesting machinery, in particular, to a feeding and chopping maintenance posture adjusting device. In addition, the present application also relates to a silage harvester comprising the feeding and chopping maintenance posture adjusting device. BACKGROUND

[0002] With the continuous development of the national economy, people's demand for living standards gradually increases, and the demand for meat products and dairy products is increasing, so the development pace of the livestock industry needs to be accelerated. The silage harvester (hereinafter referred to as the silage harvester) as a kind of high-efficiency harvesting machinery for silage provides favorable support for the rapid development of the livestock industry. The silage harvester mainly consists of a cutting table, a feeding assembly, a chopping assembly, a crushing assembly and a throwing assembly, etc. to realize the harvesting, feeding, chopping, grain crushing and throwing operations of the silage material. During the long-term operation of the silage harvester, the main working parts need to be frequently maintained, especially the scraper in the feeding assembly and the knife roller in the chopping assembly. If they are not repaired in time or the repair is difficult, it will directly affect the operation efficiency of the silage harvester and greatly increase the repair cost. Therefore, how to realize the quick maintenance of the feeding assembly and the chopping assembly is very important.

[0003] However, in most of the current silage harvesters, only the feeding assembly and the chopping assembly can be opened in a V-shaped state in the vertical plane, and the maintenance space is very small in this state due to the interference of the connecting structure between the upper ends of the feeding assembly and the chopping assembly, so the repair difficulty is great. Therefore, in the existing silage harvester, the feeding assembly is usually hung on the chopping assembly, so that the feeding assembly can be directly removed from the chopping assembly when maintenance is needed. For example, the utility model patent CN219741286U discloses a silage harvester feeding system hanging and detaching device and a silage harvester. Through the mutual cooperation of the installation frame, the chopping system, the feeding system, the stretching assembly and the driving assembly, the hanging and detaching actions of the feeding system and the chopping system are flexibly and quickly realized. However, due to the need for mechanical movement and disassembly of the feeding assembly, the hanging-detaching-hanging maintenance method requires a lot of maintenance time, the maintenance efficiency is low, and the maintenance operation is very complex, which requires high maintenance personnel. Correspondingly, the working time of the silage harvester is reduced, which may cause the silage crops to be unable to be harvested in time, resulting in economic losses to farmers. SUMMARY

[0004] The present application provides a feeding and chopping maintenance posture adjusting device and a silage harvester to solve the technical problems of low maintenance efficiency and complex maintenance operation of the main working parts in the existing silage harvester.

The component is attached to the shredding assembly; and when it is necessary to inspect the main working parts of the feeding assembly and the shredding assembly, the feeding assembly and the shredding assembly can be adjusted to the following inspection postures: 1. The first sliding assembly and the second sliding assembly cooperate, and under the action of the pushing assembly, the feeding assembly is arranged in a V-shape in the vertical plane relative to the shredding assembly, so as to carry out inspection in this inspection posture; 2. The first sliding assembly and the second sliding assembly cooperate, and under the action of the pushing assembly, the feeding assembly is arranged in an inverted V-shape in the vertical plane relative to the shredding assembly, so as to carry out inspection in this inspection posture; 3. The first sliding assembly and the second sliding assembly cooperate, so that the feeding assembly can be arranged in a side-open posture in the horizontal plane relative to the shredding assembly, so as to carry out inspection in this inspection posture. Furthermore, the above three maintenance postures can occur simultaneously with the following two connection postures: 1. The shredding component is driven to rotate relative to the mounting frame by the lifting component, so that the shredding component tilts forward or backward relative to the mounting frame; 2. The first sliding component and the second sliding component cooperate to push the feeding component horizontally relative to the shredding component a preset distance in the horizontal plane under the action of the pushing component.

Furthermore, both the forward or backward tilting of the shredding component relative to the mounting frame and the horizontal movement of the feeding component relative to the shredding component a preset distance in the horizontal plane can occur simultaneously without interference or obstruction, making the maintenance posture of the feeding and shredding components flexible and versatile. This solution utilizes the coordinated operation of a lifting component, a pushing component, a first sliding component, and a second sliding component to adjust the feeding component and the shredding component to the optimal maintenance posture, thereby enabling rapid maintenance. Compared to existing technologies, maintenance only requires adjusting the maintenance posture, simplifying the maintenance operation, ensuring sufficient maintenance space, resulting in high maintenance efficiency, short maintenance time, strong practicality, and wide applicability for promotion and application.

The pushing assembly 600 is used to push the feeding assembly 400 to rotate vertically or move horizontally relative to the shredding assembly 300. The first sliding assembly 700 and the second sliding assembly 800 are cooperated to fix the feeding assembly 400 relative to the shredding assembly 300, or make the feeding assembly 400 be arranged in V-shaped posture in the vertical plane relative to the shredding assembly 300 under the action of the pushing assembly 600, or make the feeding assembly 400 be arranged in inverted V-shaped posture in the vertical plane relative to the shredding assembly 300 under the action of the pushing assembly 600, or make the feeding assembly 400 be arranged in side opening posture in the horizontal plane relative to the shredding assembly 300, and / or make the feeding assembly 400 move horizontally relative to the shredding assembly 300 by a preset distance under the action of the pushing assembly 600. Optionally, the lifting assembly 500 is one of an oil cylinder, a gas cylinder or an electric push rod.

[0038] As Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, specifically, the feeding and shredding maintenance posture adjusting device of the present application, the tire assembly 200 is installed on the mounting frame 100, the shredding assembly 300 is rotatably installed on the mounting frame 100 and located between the tire assembly 200, and the lifting assembly 500 is arranged between the mounting frame 100 and the shredding assembly 300, so that the space on the mounting frame 100 is utilized compactly, thereby saving the overall space; between the shredding assembly 300 and the feeding assembly 400, the first side of the upper end of the shredding assembly 300 and the first side of the upper end of the feeding assembly 400 are respectively hinged by the pushing assembly 600, the first side of the lower end of the feeding assembly 400 is hinged by the first sliding assembly 700 installed on the first side of the lower end of the shredding assembly 300, the second side of the lower end of the feeding assembly 400 is detachably connected with the second side of the lower end of the shredding assembly 300 by the second sliding assembly 800 installed on the second side of the lower end of the shredding assembly 300, so as to hang the feeding assembly 400 on the shredding assembly 300; and when the main working parts in the feeding assembly 400 and the shredding assembly 300 need to be maintained, the feeding assembly 400 and the shredding assembly 300 can be adjusted to the following maintenance postures: 1, the first sliding assembly 700 and the second sliding assembly 800 cooperate, and the feeding assembly 400 is arranged in a V-shaped posture in the vertical plane relative to the shredding assembly 300 under the action of the pushing assembly 600, so as to be maintained in this maintenance posture; 2, the first sliding assembly 700 and the second sliding assembly 800 cooperate, and the feeding assembly 400 is arranged in an inverted V-shaped posture in the vertical plane relative to the shredding assembly 300 under the action of the pushing assembly 600, so as to be maintained in this maintenance posture; 3, the first sliding assembly 700 and the second sliding assembly 800 cooperate, and the feeding assembly 400 can be arranged in a side opening posture in the horizontal plane relative to the shredding assembly 300, so as to be maintained in this maintenance posture. And the above three maintenance postures can appear at the same time with the following two connection postures: 1, the shredding assembly 300 is driven to rotate relative to the mounting frame 100 by the lifting assembly 500, so that the shredding assembly 300 is inclined forward or backward relative to the mounting frame 100; 2, the first sliding assembly 700 and the second sliding assembly 800 cooperate, and the feeding assembly 400 is pushed to move a preset distance in the horizontal plane relative to the shredding assembly 300 under the action of the pushing assembly 600.That is, the feeding assembly 400 can be first moved horizontally relative to the chopping assembly 300 by a preset distance, and then arranged in a V-shaped posture in the vertical plane, or arranged in an inverted V-shaped posture in the vertical plane, or arranged in a side opening posture in the horizontal plane; or the feeding assembly 400 can be first arranged in a V-shaped posture in the vertical plane, or arranged in an inverted V-shaped posture in the vertical plane, or arranged in a side opening posture in the horizontal plane relative to the chopping assembly 300, and then moved horizontally relative to the chopping assembly 300 by a preset distance; and the two connection postures of the forward or backward inclination of the chopping assembly 300 relative to the mounting frame 100 and the horizontal movement of the feeding assembly 400 relative to the chopping assembly 300 by a preset distance in the horizontal plane can also occur simultaneously, without interfering with each other, so that the maintenance posture of the feeding assembly 400 and the chopping assembly 300 is flexible and variable. The present scheme cooperates the lifting assembly 500, the moving assembly 600, the first sliding assembly 700 and the second sliding assembly 800 to adjust the feeding assembly 400 and the chopping assembly 300 to the best maintenance posture, so as to realize rapid maintenance. Compared with the prior art, only the maintenance posture needs to be adjusted during maintenance, the maintenance operation is simple, sufficient maintenance space is ensured, the maintenance efficiency is high, the maintenance time is short, the practicality is strong, and the present scheme is suitable for wide popularization and application.

[0039] As shown in Figure 2 It should be understood that, in the present embodiment, when the feeding assembly 400 is arranged in a V-shaped posture in the vertical plane relative to the chopping assembly 300, the second side of the upper end of the feeding assembly 400 and the second side of the upper end of the chopping assembly 300 are open, so that there is also a larger maintenance space for maintenance in this state.

[0040] It should be understood that, when the lifting assembly 500 drives the chopping assembly 300 to incline forward or backward relative to the mounting frame 100, the feeding assembly 400 is synchronously inclined forward or backward relative to the mounting frame 100, and at this time, the feeding assembly 400 can be arranged in a side opening posture in the inclined plane relative to the chopping assembly 300.

[0041] It should be understood that the preset distance can be adaptively selected according to the maintenance requirements.

[0042] It should be understood that the main working components in the feeding assembly 400 are scrapers, and the main working components in the chopping assembly 300 are fixed blades and moving blades.

[0043] It should be understood that when the feeding assembly 400 is arranged in a V-shaped posture in the vertical plane or in an inverted V-shaped posture in the vertical plane relative to the chopping assembly 300, the posture of the feeding assembly 400 and the chopping assembly 300 can be fixed by cooperation of the first sliding assembly 700 and the second sliding assembly 800, so as to ensure the structural stability.

Specifically, the first sliding rail 740 is installed through the first mounting seat 730, the first limiting pin 720 is inserted into different first plug-in holes to limit different sliding distances of the first sliding member relative to the first support member, and the two first sliding grooves are in rolling cooperation with the first sliding member to limit the first sliding member in the horizontal direction while reducing the sliding resistance of the first sliding member relative to the first sliding rail 740.
