Description

Technical Field

[0001] The invention relates to agricultural mechanical equipment, and more specifically to a corn cutting platform buffering and conveying mechanism. Background Art

[0002] In the prior art, the corn harvester of a small corn harvester has multiple groups of cutting and conveying channels. After the harvester cuts off the root stalk of the corn, the cutting part at the bottom of each group of conveying channels pulls the entire corn stalk downward and cuts it. The corn on the stalk is blocked by the blocking part and conveyed to the end auger, which collects several groups of corn and conveys them to the discharge port on one side. However, when the corn enters the auger, there is a risk of collision with the edge of the continuously rotating auger. If a hard collision or squeezing occurs, the corn itself will be directly injured, resulting in a decrease in the yield of corn harvesting, which is a direct economic loss for the user. Compared with ordinary belt conveying mechanisms, the auger has many advantages such as simple structure, wide conveying coverage, and no impurities stuck in the structural gap. Therefore, it is necessary to optimize the corn harvester with an auger conveying structure to avoid damage to the corn by the auger. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a corn harvesting platform buffer conveying mechanism, thereby avoiding the defects in the above prior art, reducing damage to corn, and improving the yield rate of corn harvest.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a corn cutting table buffer conveying mechanism, comprising a cutting table bracket, a plurality of cutting parts are horizontally arranged at the front of the cutting table bracket, guide walls for guiding the corn stalks to correspond to the cutting parts are arranged on both sides of the cutting parts, a conveying channel is formed on the upper part of the cutting parts and corn blocking parts are arranged on both sides of the conveying channel, an auger is horizontally arranged at the end of the conveying channel, a discharge port is arranged at the rear side of one end of the auger, and a buffer conveying mechanism is also arranged under the receiving bottom plate of the auger, the buffer conveying mechanism comprises an inclined slide, a loading hopper and a lifting drive part, the end of the conveying channel is connected to a lower slide, and an inclined slide is arranged at the lower part of the end of the lower slide, so that the corn at the end of the conveying channel slides along the lower slide to the inclined slide, and the inclined slide slides along the auger It is arranged axially, and the inclined slide is inclined from the output end to the input end of the auger, so that the corn that falls to the inclined slide slides down toward the input end of the auger for collection. A loading hopper is set at the end of the inclined slide to receive the corn that slides down. A lifting drive is set at the bottom of the loading hopper. No material receiving bottom plate is arranged at the auger above the loading hopper. The loading hopper is controlled by the lifting drive to rise and fall intermittently. When the idle gear at the input end of the auger rotates to the top of the loading hopper, the lifting drive drives the loading hopper to rise, so that the corn on the loading hopper corresponds to the auger, and the corn on the loading hopper is shoveled away and transported along the auger during the continuous rotation of the auger. After the auger completes the corn transfer, the lifting drive drives the loading hopper to descend and reset to receive the next batch of corn.

[0005] As an improvement, the loading hopper has two stop positions: raised to the position and lowered to the position. When the loading hopper is in the lowered position, the height of the loading hopper is lower than the height of the end of the inclined slide. The area of ​​the loading hopper plus the height difference between the loading hopper and the end of the inclined slide form a transfer carrying space for corn.

[0006] As an improvement, the front and rear ends of the hopper are used to limit the corn by front and rear baffles set on the cutting platform bracket, and the left and right ends of the hopper form upward arc walls larger than the outer circumference of the auger to limit the corn. When the hopper rises to the point where the corn corresponds to the auger, the auger continues to rotate and shovels the corn on the hopper along the arc wall.

[0007] As an improvement, the loading hopper is further provided with a downwardly extending blocking wall on the side facing the inclined slide. When the loading hopper rises to the point where the corn corresponds to the auger, the blocking wall rises to the end of the corresponding inclined slide to block the corn.

[0008] As an improvement, the upper surface of the loading hopper for receiving materials is set to an arc shape consistent with the arc of the auger. When the loading hopper rises until the corn corresponds to the auger, the auger continues to rotate and shovels the corn on the loading hopper along the arc of the upper surface.

[0009] As an improvement, the inclined slide is arranged as a plurality of sections connected in sequence, the number of sections is consistent with the number of conveying channels and is arranged accordingly, and the head and tail connections of each section have a height difference.

[0010] The beneficial effects of the present invention include avoiding the possibility of damage caused by the traditional structure of directly conveying corn to the auger, first buffering the corn, and then conveying the corn to the auger in an orderly manner from the idle space at the auger input end by means of transfer, so that the corn is intermittently output from the auger to the discharge port, the amount of corn is stable and orderly, and the possible congestion and squeezing of corn caused by the large wave of corn conveyed from the discharge port to the subsequent mechanism is avoided, thereby ensuring the corn harvest yield and reducing losses as a whole.

[0016] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 , 2 , 3, 4, and 5 are specific embodiments of the corn cutting table buffer conveying mechanism of the present invention. The drawings only express the mutual coordination relationship between the structures. The positions and size ratios of the specific structures can be reasonably adjusted according to the actual product conditions, and do not limit the scope of protection of the present invention.

[0018] A specific embodiment includes a header bracket 1, a plurality of cutting parts 2 are horizontally arranged at the front of the header bracket 1, guide walls 3 for guiding corn stalks to correspond to the cutting parts 2 are arranged on both sides of the cutting parts 2, a conveying channel 4 is formed on the upper part of the cutting part 2 and corn blocking parts 41 are arranged on both sides of the conveying channel 4, an auger 5 is horizontally arranged at the end of the conveying channel 4, a discharge port 6 is arranged at the rear side of one end of the auger 5, and a buffer conveying mechanism 7 is also arranged under the receiving bottom plate 51 of the auger 5, the buffer conveying mechanism 7 includes an inclined slide 71, a loading hopper 72 and a lifting drive member 73, the end of the conveying channel 4 is connected to a lower slide 42, and an inclined slide 71 is arranged at the lower end of the lower slide 42, so that the corn at the end of the conveying channel 4 slides along the lower slide 42 to the inclined slide 71, and the inclined slide 71 is arranged along the axial direction of the auger 5, and the inclined slide 71 is driven by the auger The output end of the auger 5 is inclined toward the input end, so that the corn that falls to the inclined slide 71 slides down toward the input end of the auger 5 for collection. A loading hopper 72 is set at the end of the inclined slide 71 to receive the corn that slides down. A lifting drive component 73 is set at the bottom of the loading hopper 72. The auger 5 above the loading hopper 72 is not arranged with a material receiving bottom plate 51. The loading hopper 72 is controlled by the lifting drive component 73 to perform intermittent ascent and descent. When the idle gear at the input end of the auger 5 rotates to the top of the loading hopper 72, the lifting drive component 73 drives the loading hopper 72 to rise, so that the corn on the loading hopper 72 corresponds to the auger 5. During the continuous rotation of the auger 5, the corn on the loading hopper 72 is shoveled away and transported along the auger 5; after the auger completes the corn transfer, the lifting drive component 73 drives the loading hopper 72 to descend and reset to receive the next batch of corn.

[0019] When the present invention is in use, the harvester bracket 1 is installed on the front of the main body of the harvester, and the user drives the corn harvester to correspond to the corn plants to be harvested. As the corn harvester moves forward, the corn stalks are gathered to the middle by the guide walls 3 on both sides to the cutting part 2. The cutting part 2 is a pair of cutting shafts, which rotate relative to each other to pull the corn stalks downward and cut them. The corn cobs on the stalks are blocked by the corn blocking part 41 after being cut off. As the harvester moves forward and the corn plants entering the conveying channel 4 and the corn are pushed backward, the corn is transported to the end of the conveying channel 4, and the corn slides along the lower slide 42 to the inclined slide 71. Multiple groups of corn in the conveying channels 4 fall onto the inclined slides 71 at different positions one after another, and then gradually fall to the loading hopper 72 for collection by rolling and sliding due to the weight of the corn and the vibration of the harvester. The driving of the loading hopper 72 by the lifting drive 73 can be set according to the number of rotations of the auger 5. For example, one or two rotations of the auger 5 is a cycle. After running one or two circles, when the auger 5 of the next circle runs to the top of the loading hopper 72 in the idle position, the lifting drive 73 starts to lift the loading hopper 72, and lifts the batch of corn to the position of the auger 5. During the continuous rotation of the auger 5, the corn on the loading hopper 72 can be shoveled away by its spiral blades and transported to the discharge port 6 at the output end along the auger 5. The so-called idle position of the auger 5 is the part of the spiral blade above the circumferential position. The idle position corresponds to the timing above the loading hopper 72 to complete the rising and transportation of corn by determining the rotation speed of the auger 5, which can effectively avoid the hard collision between the corn and the auger 5; after the loading hopper 72 is lowered and reset, it can receive the next batch of corn, and continue to rise and transport in the idle position after the auger 5 runs one or two circles. The corn transportation method of the present invention also realizes the intermittent output of corn, that is, within the rated time of the auger 5 running one or two circles, the corn is first collected at the loading hopper 72, and then transported into the auger 5 to be transported to the output end, which well determines the waves of corn transported in the auger 5, and the corn arriving at the discharge port 6 and sent to the subsequent process is orderly and the quantity is within a certain range, which is convenient for the processing of the subsequent process, and avoids the congestion and squeezing of corn caused by a large wave of corn entering the auger 5 and being transported from the discharge port 6 to the subsequent process, thereby ensuring the corn harvest yield and reducing losses as a whole.

[0020] As an improved specific implementation method, the loading hopper 72 has two stop positions, namely, a raised position and a lowered position. When the loading hopper 72 is in the lowered position, the height of the loading hopper 72 is lower than the height of the end of the inclined slide 71. The area of ​​the loading hopper 72 plus the height difference between the loading hopper 72 and the end of the inclined slide 71 form a transfer carrying space for corn.

[0021] like Figure 3As shown, in the specific implementation, in order to avoid the confusion of the process of the auger 5 rotating to shovel away the corn caused by too much corn being transported in a batch, or even damaging the corn, or too much corn being transported causing crowding and squeezing of the corn in the subsequent process, the stop position of the loading hopper 72 is specifically designed. When it is lowered to the right position, the loading hopper 72 directly receives the corn at a position lower than the height of the end of the inclined slide 71. When the loading hopper 72 relies on its own bucket-shaped structure, its area cooperates with the side wall to accommodate the corn. The loading hopper 72 is surrounded by the solid inner wall of the header bracket 1. If a batch of corn overflows from the loading hopper 72, it will be limited by the solid inner wall of the surrounding header bracket 1, and the corn will be piled at the end of the loading hopper 72; when the loading hopper 72 rises to transport the corn, the overflowing corn will fall back to the end of the inclined slide 71, thereby controlling the amount of corn transported by the loading hopper 72 at a single time, and will not exceed the load to be controlled. After the transfer is completed and the hopper is lowered and reset, the corn at the end of the inclined slide 71 continues to fall into the loading hopper 72 and wait for transfer.

[0022] As an improved specific implementation method, the front and rear ends of the loading hopper 72 are used to limit the corn by the front and rear baffles 11 arranged on the cutting platform bracket 1, and the left and right ends of the loading hopper 72 form an arc wall 721 larger than the outer circumference of the auger 5 to limit the corn. When the loading hopper 72 rises to the point where the corn corresponds to the auger 5, the auger 5 continues to rotate and shovels the corn on the loading hopper 72 along the arc wall 721.

[0023] like Figure 4 , 5 As shown, the front and rear baffles 11 are the solid inner walls of the harvesting platform bracket 1, and left and right baffles are also provided on the left and right sides during specific implementation; as an optimization, the left and right side walls of the loading hopper 72 are set as arc-shaped walls 721, which on the one hand provide a good accommodating space for carrying corn, and on the other hand, when the loading hopper 72 rises to transport corn, the arc-shaped walls 721 adapt to the outer circumferential size of the spiral blades of the auger 5, so that the corn on the loading hopper 72 can be shoveled away along the arc-shaped walls 721 during the rotation of the auger 5, or the corn can roll and slide more smoothly and fall into the blades of the auger 5 to avoid damage to the corn.

[0024] As an improved specific implementation method, the loading hopper 72 is further provided with a downwardly extending blocking wall 722 on the side facing the inclined slide 71. When the loading hopper 72 rises to the corn corresponding to the auger 5, the blocking wall 722 rises to the end of the corresponding inclined slide 71 to block the corn.

[0025] like Figure 4 , 5 As shown, after the loading hopper 72 rises, the blocking wall 722 rises to effectively block the end of the inclined slide 71, ensuring that the corn is blocked in an orderly manner. After the loading hopper 72 and the blocking wall 722 descend, the loading hopper 72 can continue to receive the corn falling from the inclined slide 71.

[0026] As an improved specific implementation method, the upper surface of the loading hopper 72 for receiving materials is set to an arc shape consistent with the arc of the auger 5. When the loading hopper 72 rises until the corn corresponds to the auger 5, the auger 5 continues to rotate and shovels the corn on the loading hopper 72 along the arc of the upper surface.

[0027] like Figure 5 As shown, the upper surface of the loading hopper 72 for receiving materials is preferably used together with the arc wall 721 to form an overall arc shape, so that the corn on the loading hopper 72 can be shoveled away along the arc wall 721 and the arc of the upper surface during the continuous rotation of the auger 5, or the corn can roll and slide more smoothly and fall into the blades of the auger 5 to avoid damage to the corn.

[0028] As an improved specific implementation, the inclined slide 71 is configured as a plurality of sections connected in sequence, the number of sections is consistent with the number of the conveying channels 4 and is configured accordingly, and the head and tail connections of each section have a height difference.

[0029] This embodiment is not shown in the figure. In actual implementation, the multi-section inclined slide 71 is easy to be processed separately and then spliced ​​at the head and tail, which can reduce the manufacturing cost and difficulty. When used in docking, the head and tail connections of each section have a height difference, thereby forming a gradually descending step state. When the corn rolls and slides to the step, it will fall, thereby achieving a pause state, which can effectively reduce the descending speed of the corn, avoid the impact force when the corn falls quickly to the loading hopper 72, and reduce the possibility of damage to the corn.

[0030] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
