A forage harvester

Abstract

This invention discloses a forage collector for a corn harvester, relating to the field of corn silage technology. The forage collector for this corn harvester includes a corn silage harvester with a cab fixedly connected to its top and a discharge device movably connected to its top. The forage collector works by rotating a guide rod, which drives a rotating rod to rotate the conveyor mesh. The outer edge of the conveyor mesh is sharp, conveying corn stalks to the top of the mesh. A first telescopic rod continuously extends and retracts, causing the rotating rod to vibrate left and right, shaking off some of the soil and impurities scraped up during corn transport. The corn stalks are then fed upwards between the first and second conveyor wheels, into the feed inlet, thus processing fallen corn stalks and improving overall harvesting efficiency.

Description

Technical Field

[0001] This invention relates to the field of corn silage technology, specifically to a forage collector for a corn harvester. Background Technology

[0002] A corn silage harvester is an agricultural machine specifically designed for harvesting and processing corn for silage. It can efficiently cut corn stalks in their green stage and chop them into feed suitable for silage.

It also includes a cutting platform device installed at the bottom of the vertical beam and a crushing device connected to the cutting platform device. A conveying pipe is connected to the crushing device.

[0004] Existing harvesters used for corn silage have difficulty processing fallen corn stalks when working in the field. Often, after the machine has harvested one plot, the stalks need to be processed again, which affects the overall harvesting efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a forage collector for a corn harvester, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a forage collector for a corn harvester, comprising a corn silage harvester, wherein a cab is fixedly connected to the top of the corn silage harvester, a discharge device is movably connected to the top of the corn silage harvester, wheels are movably connected to the outer wall of the corn silage harvester, a cutting plate is fixedly connected to the front of the corn silage harvester, a stalk feeding mechanism is fixedly connected to the bottom of the cutting plate, a cutting mechanism is fixedly connected to the bottom of the cutting plate in front of the stalk feeding mechanism, and a feed inlet is provided on the front of the corn silage harvester at the top of the cutting plate;

[0007] The straw feeding mechanism includes:

[0008] A motor mounting bracket is fixedly connected to the bottom of the cutting plate;

[0009] A drive motor, which is fixedly connected inside a motor mounting bracket;

[0010] Rotate the guide rod, which is fixedly connected to the left side of the motor mounting bracket.

[0011] Preferably, the corn silage harvester has inner guide wheels fixedly connected to the left and right sides of the feed inlet on the front side, and side frames fixedly connected to the outside of the two inner guide wheels on the front side. A front fixed frame is fixedly connected to the top of the side frames on the front side, and straw pressing is fixedly connected inside the front fixed frame. The bottom of both side frames is movably connected to straw feeding wheels, and the bottom of the front fixed frame is movably connected to two straw feeding wheels. Both the inner guide wheels and the straw feeding wheels can rotate independently.

[0012] Preferably, a rotating fixing frame is movably connected to the right side of the rotating guide rod, and the rotating fixing frame is fixedly connected to the bottom of the cutting plate. A rotating rod is movably connected to the outer wall of the rotating guide rod.

[0013] Preferably, several conveying mesh blades are fixedly connected to the outer wall of the rotating rod, and two first telescopic rods are fixedly connected to the right side of the rotating rod, with the right side of each of the two first telescopic rods being fixedly connected to the rotating guide rod.

[0014] Preferably, a first conveying wheel is movably connected inside the cutting plate at the corresponding position at the top of the rotating rod, and a motor that drives the first conveying wheel is fixedly connected inside the cutting plate to make the first conveying wheel rotate. A second conveying wheel is movably connected inside the cutting plate in front of the first conveying wheel, and a motor that drives the second conveying wheel is fixedly connected inside the cutting plate to make the second conveying wheel rotate in the opposite direction to the rotation of the first conveying wheel.

[0015] Preferably, the cutting mechanism includes a fixing rod, which is fixedly connected to the bottom of the cutting plate located on the front of the conveyor mesh leaf, and four fixing rods are provided. A fixing groove is fixedly connected to the bottom of the fixing rod, and an upper fixing blade is fixedly connected to the front of the fixing groove.

[0016] Preferably, a lower sliding blade is movably connected inside the fixed groove at the bottom of the upper fixed blade, a second telescopic rod is fixedly connected to the left side of the lower sliding blade, a side-changing fixing frame is fixedly connected to the left side of the second telescopic rod, and the side-changing fixing frame is fixedly connected to the left side of the fixed groove.

[0017] Preferably, the bottom of the sliding blade is fixedly connected to several lower fixing plates, each of the lower fixing plates is fixedly connected to a side pressure plate at its bottom, and each of the side pressure plates is fixedly connected to a front inclined pressure plate on its front side.

[0018] This invention provides a forage collector for a corn harvester. It has the following beneficial effects:

[0019] 1. The forage collector of this corn harvester, by rotating the guide rod, drives the rotating rod to rotate the conveyor mesh. The outer side of the conveyor mesh is sharp, which conveys the corn stalks to the top of the conveyor mesh. During the rotation of the rotating rod, the first telescopic rod will continuously extend and retract, causing the rotating rod to shake left and right. This allows the conveyor mesh to shake off some of the soil and impurities scraped up when conveying corn, and then feed the corn stalks upward between the first and second conveyor wheels, thus feeding the corn stalks into the feed inlet. This process treats the fallen corn stalks and improves the overall harvesting efficiency.

[0020] 2. The forage collector of this corn harvester, by continuously extending and retracting the second telescopic rod before the fallen corn stalks are fed between the first and second conveyor wheels by the conveyor mesh, causes the lower sliding blade and the upper fixed blade to move continuously. This causes the lower sliding blade and the upper fixed blade to cut the fallen corn stalks, making it easier for the corn stalks to be fed between the first and second conveyor wheels by the conveyor mesh, thereby improving the corn harvesting efficiency.

[0021] 3. The forage collector of this corn harvester, through the back-and-forth movement of the sliding blades, simultaneously causes the bottom fixed plate to swing back and forth. This movement of the fixed plate causes the bottom side pressure plates to swing as well, pressing the ground flat. The front inclined pressure plate then pushes down any loose stones and protruding soil into the compacted soil, which is then further compacted by the side pressure plates. This further prevents the conveyor belt from being affected by the soil in the field when transporting the straw upwards, thus avoiding the stirring up of impurities and improving the quality of the corn harvest, indirectly increasing the harvesting efficiency.

[0022] 4. The forage collector of this corn harvester uses upper fixed blades and lower sliding blades to cut the fallen corn stalks. Since the upper fixed blades and lower sliding blades are inclined to the ground, they will transport the corn stalks upwards as the corn silage harvester moves forward, thus facilitating the conveyor mesh to transport the corn stalks upwards and improving the corn harvesting efficiency.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0036] Example 1: Please refer to Figure 1-9The present invention provides a technical solution: a forage collector for a corn harvester, including a corn silage harvester 1, a cab 12 fixedly connected to the top of the corn silage harvester 1, a discharge device 13 movably connected to the top of the corn silage harvester 1, wheels 11 movably connected to the outer wall of the corn silage harvester 1, a cutting plate 4 fixedly connected to the front of the corn silage harvester 1, a stalk feeding mechanism 2 fixedly connected to the bottom of the cutting plate 4, a cutting mechanism 3 fixedly connected to the bottom of the cutting plate 4 on the front of the stalk feeding mechanism 2, and a feed inlet 19 provided on the front of the corn silage harvester 1 on the top of the cutting plate 4;

[0037] Stalk feeding mechanism 2 includes:

[0038] Motor mounting bracket 201 is fixedly connected to the bottom of cutting plate 4;

[0039] The drive motor 202 is fixedly connected inside the motor mounting bracket 201.

[0040] Rotate the guide rod 203, which is fixedly connected to the left side of the motor mounting bracket 201.

[0041] The corn silage harvester 1 has inner guide wheels 18 fixedly connected to the left and right sides of the feed inlet 19 on the front. Side frames 14 are fixedly connected to the outside of the two inner guide wheels 18 on the front. A front fixed frame 15 is fixedly connected to the top of the side frames 14 on the front. The front fixed frame 15 has straw pressing 17 fixedly connected inside. The bottom of the two side frames 14 is movably connected to straw feeding wheels 16. The bottom of the front fixed frame 15 is movably connected to two straw feeding wheels 16. The inner guide wheels 18 and the straw feeding wheels 16 can rotate on their own.

[0042] A rotating fixed frame 207 is movably connected to the right side of the rotating guide rod 203, and the rotating fixed frame 207 is fixedly connected to the bottom of the cutting plate 4. A rotating rod 205 is movably connected to the outer wall of the rotating guide rod 203.

[0043] Several conveying mesh leaves 206 are fixedly connected to the outer wall of the rotating rod 205. Two first telescopic rods 204 are fixedly connected to the right side of the rotating rod 205. The right side of the two first telescopic rods 204 is fixedly connected to the rotating guide rod 203. During the rotation of the rotating rod 205, the first telescopic rods 204 will continuously extend and retract to make the rotating rod 205 shake left and right, so that the conveying mesh leaves 206 shake off some of the soil and impurities scraped up when conveying corn.

[0044] Inside the cutting plate 4, at the position corresponding to the top of the rotating rod 205, a first conveying wheel 208 is movably connected. Inside the cutting plate 4, a motor is fixedly connected to drive the first conveying wheel 208 to rotate. Inside the cutting plate 4, at the front of the first conveying wheel 208, a second conveying wheel 209 is movably connected. Inside the cutting plate 4, a motor is fixedly connected to drive the second conveying wheel 209 to rotate in the opposite direction to the rotation of the first conveying wheel 208.

[0045] In operation, the operator sits inside the cab 12 and drives the corn silage harvester 1 through the cornfield. The front of the cutting plate 4, in conjunction with the stalk feeding wheel 16, feeds the corn stalks into the feed inlet 19. The front of the cutting plate 4 is relatively sharp and cuts the corn. Under the action of the pressing straw 17, the bottom of the straw faces the feed inlet 19. Guided by the two inner guide wheels 18, the corn is fed into the feed inlet 19 and crushed inside the corn silage harvester 1. It is then discharged from the discharge device 13. The corn stalks that have already fallen to the ground in the field are further crushed by the drive motor 202 as the corn silage harvester 1 moves forward. The rotating guide rod 203 rotates the rotating guide rod 205, which in turn rotates the conveyor mesh 206. The tip of the conveyor mesh 206 is more closely aligned with the corn silage harvester 1. The near-ground design prevents corn stalks from being missed. The sharp outer edge of the conveyor mesh 206 better guides the corn stalks to the top of the conveyor mesh 206. As the rotating rod 205 is driven to rotate, the first telescopic rod 204 continuously extends and retracts, causing the rotating rod 205 to vibrate left and right. This allows the conveyor mesh 206 to shake off some of the soil and impurities that are scraped up while conveying corn, and also to shake off the soil adhering to the surface of the fallen corn stalks. The corn stalks are then fed upwards between the first conveyor wheel 208 and the second conveyor wheel 209. The first conveyor wheel 208 and the second conveyor wheel 209 rotate to feed the corn stalks into the feed inlet 19, where they are then crushed inside the corn silage harvester 1, thus processing the fallen corn stalks.

[0046] Example 2: Please refer to Figure 1-10 Based on Embodiment 1, the present invention provides a technical solution:

[0047] The cutting mechanism 3 includes a fixed rod 301, which is fixedly connected to the bottom of the cutting plate 4 and located on the front of the conveyor mesh leaf 206. There are four fixed rods 301. The bottom of the fixed rod 301 is fixedly connected to a fixed groove 302, and the front of the fixed groove 302 is fixedly connected to an upper fixed blade 303.

[0048] Inside the fixed groove 302, a lower sliding blade 306 is movably connected to the bottom of the upper fixed blade 303. A second telescopic rod 305 is fixedly connected to the left side of the lower sliding blade 306. A side-changing fixing frame 304 is fixedly connected to the left side of the second telescopic rod 305, and the side-changing fixing frame 304 is fixedly connected to the left side of the fixed groove 302. The second telescopic rod 305 continuously extends and retracts, causing the lower sliding blade 306 and the upper fixed blade 303 to continuously move, so that the lower sliding blade 306 and the upper fixed blade 303 will cut the corn stalks that have fallen to the ground.

[0049] The bottom of the sliding blade 306 is fixedly connected to several lower fixed plates 307. Each lower fixed plate 307 is fixedly connected to a side pressure plate 308 at its bottom. Each side pressure plate 308 is fixedly connected to a front inclined pressure plate 309 on its front. When the side pressure plate 308 is shaken and moved, the two sides of the side pressure plate 308 will press the ground, making the ground flat. The front inclined pressure plate 309 will press the gravel and protruding soil in front into the soil, and then compact them by the side pressure plate 308.

[0050] In use, before the fallen corn stalks are fed between the first conveyor wheel 208 and the second conveyor wheel 209 by the conveyor mesh 206, the second telescopic rod 305 continuously extends and retracts, causing the lower sliding blade 306 and the upper fixed blade 303 to move continuously. This allows the lower sliding blade 306 and the upper fixed blade 303 to cut the fallen corn stalks, making it easier for the corn stalks to be fed between the first conveyor wheel 208 and the second conveyor wheel 209 by the conveyor mesh 206. When the lower sliding blade 306 moves back and forth, it also causes the lower fixed plate 307 at the bottom to move back and forth. When the lower fixed plate 307 moves, it causes the side pressure plate 308 at the bottom to move accordingly, thus causing the side pressure plate 308 to move. The two sides of 08 serve to press down the ground, making the ground flat. The front inclined pressing plate 309 presses down the gravel and protruding soil in front into the compacted soil. The side pressing plate 308 then compacts it. This further prevents the conveyor mesh 206 from being affected by the soil in the field when it rotates to transport the straw upwards, thus avoiding the scooping up of some impurities. After the upper fixed blade 303 and the lower sliding blade 306 cut the fallen corn stalks, since the upper fixed blade 303 and the lower sliding blade 306 are inclined to the ground, they will transport the corn stalks upwards as the corn silage harvester 1 moves forward, thus making it easier for the conveyor mesh 206 to transport the corn stalks upwards.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
