Description

Technical Field

[0001] The present invention relates to the technical field of cotton picking equipment, in particular, to a material storage device. In addition, the present invention also relates to a box-type cotton picker comprising the material storage device. Background Art

[0002] With the development of society and the advancement of science and technology, agricultural products such as cotton are usually harvested by agricultural machinery and equipment to reduce the labor intensity of cotton farmers, reduce crop losses and waste, and bring significant economic benefits to agricultural production.

[0003] At present, cotton harvesting equipment mainly includes box-type cotton pickers and baling cotton pickers. Among them, box-type cotton pickers are more flexible in design and use. They can adapt to cotton fields with different planting patterns and row spacings. They are more advantageous in some specific areas or small cotton fields. The initial purchase cost of box-type cotton pickers is relatively low, so they have been widely used.

[0004] The box-type cotton picker collects the harvested cotton through the cotton box, which is a storage device. Therefore, the larger the capacity of the cotton box, the higher the operating efficiency of the box-type cotton picker. However, in order to reasonably layout the components and ensure the passability during transportation, the volume of the cotton box on the box-type cotton picker is often relatively fixed. Therefore, the existing cotton box is equipped with a compacting auger and other devices to help evenly distribute the cotton in the cotton box and assist in compacting the fluffy cotton, so as to increase the capacity of the cotton box when the volume is relatively fixed. For example, Chinese invention patent CN109392449A discloses a cotton picker, specifically, a stirring and compacting mechanism is arranged below the cotton inlet of the inner box body, including three stirring blades evenly distributed in the cotton box and a stirring motor driving each stirring blade, and the diameter of the stirring blade gradually decreases from one end close to the cotton inlet to the other end, and is cone-shaped. When the stirring and gathering rotates, on the one hand, the cotton is pressed down, and on the other hand, part of the cotton is transported inward. Under the above-mentioned "conical" structure, the diameter of the stirring and gathering blades at the end close to the cotton inlet is larger, so that the cotton entering from the cotton inlet is transported inward as much as possible to prevent excessive accumulation of cotton near the cotton inlet. And because the diameter of the stirring and gathering blades decreases as they go inward, that is, the horizontal transport volume of the stirring and gathering to the cotton decreases as they go inward, thus preventing excessive cotton from being squeezed to the inner end of the cotton box, so that the cotton is distributed in the cotton box as evenly as possible, ensuring the cotton loading capacity of the cotton box and improving the overall cotton picking efficiency.

[0005] However, in the above-mentioned cotton picker, the cotton is unloaded through an automatic cotton unloading mechanism, specifically, a reversing door rotatably connected to the bottom of the cotton box is provided on one side of the cotton box, and the reversing door is opened and closed by a door opening and closing cylinder between the two sides of the cotton box. A chain rake assembly is provided on the inner side of the reversing door and the inner bottom of the cotton box, and the chain rake assembly includes a driving shaft, a driven shaft, a plurality of sprockets provided on the driving shaft and the driven shaft, a plurality of chains connecting the driving shaft and the driven shaft through the sprockets, a chain rake provided on the plurality of chains, and a chain rake motor provided at one end of the driving shaft. When working, the chain rake motor drives the driving shaft to rotate, and the driving shaft drives the driven shaft to rotate through the sprocket and the chain, and at the same time, the chain drives the chain rake to move, and the chain rake moves to gradually rake the cotton out from the bottom of the cotton box. Although the above structure can enable the existing cotton picker to store materials in large capacity and unload materials automatically, it will result in an excessive number of driving components inside the cotton box, a very complex driving system, low reliability during actual operation, and a drive system that is prone to failure. Once a failure occurs, it is difficult to troubleshoot and repair, which greatly affects the operating efficiency of the cotton picker. Summary of the invention

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0031] Embodiment 1

[0032] like Figure 1-Figure 5As shown, the material storage device of this embodiment includes a bottom bracket 100, a box body 200, a material pressing assembly 300, a driving assembly 400, a first linkage assembly 500 and a second linkage assembly 600. The box body 200 includes a shell 210, a cover plate 220 and a valve 230. The shell 210 is rotatably connected to the bottom bracket 100. The shell 210 is provided with a horizontal discharge port arranged in a horizontal direction and a vertical discharge port arranged in a vertical direction and connected to the horizontal discharge port. The cover plate 220 is rotatably connected to the shell 210 and is used to open or close the horizontal discharge port. The valve 230 is rotatably connected to the shell 210 and is used to open or close the vertical discharge port. The material pressing assembly 300 is arranged on the shell 210 and is used to compact the material. The driving assembly 400 is respectively connected to the bottom bracket 100 and the cover plate 220. The shell 210 is connected to the bottom bracket 100 and is used to drive the shell 210 to rotate relative to the bottom bracket 100 so that the vertical discharge port and the horizontal discharge port are tilted downward or reset to the initial state, thereby performing tipping discharge or resetting storage. The first linkage assembly 500 is respectively connected to the cover plate 220 and the bottom bracket 100. The first linkage assembly 500 is used to link the cover plate 220 to open the horizontal discharge port during tipping discharge, or to link the cover plate 220 to close the horizontal discharge port during horizontal storage. The second linkage assembly 600 is respectively connected to the shell 210, the valve 230 and the bottom bracket 100. The second linkage assembly 600 is used to link the valve 230 to open the vertical discharge port during tipping discharge, or to link the valve 230 to close the vertical discharge port during horizontal storage.

[0033] like Figure 1-Figure 5As shown, specifically, the material storage device of the present invention is provided with a box body 200 installed through a bottom bracket 100, the box body 200 contains materials through a shell 210, and then the shell 210 is closed by a cover plate 220 and a valve 230 to prevent the materials in the shell 210 from being spilled, and then a material pressing assembly 300 is installed in the shell 210, so that after the materials enter the closed cavity, the materials are compacted by the material pressing assembly 300, so as to increase the material capacity under the same volume, thereby improving the working efficiency; in the initial state, the horizontal discharge port is arranged horizontally , the vertical discharge port is arranged vertically; after moving to the discharge point, the housing 210 is driven to rotate relative to the bottom bracket 100 through the driving assembly 400, so that the housing 210 is in a tilted state relative to the bottom bracket 100, and then the horizontal discharge port and the vertical discharge port are arranged tilted downward. At this time, the first linkage assembly 500 links the cover plate 220 to open the horizontal discharge port, and the second linkage assembly 600 links the valve 230 to open the vertical discharge port. Under the action of gravity, the horizontal discharge port and the vertical discharge port cooperate to achieve efficient tipping discharge; during the discharge, After completion, the driving assembly drives the housing 210 to rotate in the opposite direction relative to the bottom bracket 100 to reset. At this time, the vertical discharge port and the horizontal discharge port are reset to the initial state, and the first linkage assembly 500 links the cover plate 220 to close the horizontal discharge port, and the second linkage assembly 600 links the valve 230 to close the vertical discharge port, so that the box 200 can store materials. In this solution, the bottom bracket 100, the box 200, the pressing assembly 300, the driving assembly 400, the first linkage assembly 500 and the second linkage assembly 600 cooperate with each other. Large-capacity material storage and automatic unloading are achieved under the action of two driving components, namely the material pressing component 300 and the driving component 400, which are respectively located inside and outside the box body 200. Compared with the prior art, there is only one driving component, namely the material pressing component 300, in the box body 200, and the internal structure is simple, which greatly improves the reliability of the material storage device, thereby reducing the probability of failure. After a failure occurs, the troubleshooting and maintenance are simple, which is conducive to improving the efficiency of the box-type cotton picker using the material storage device. It has strong practicality and is suitable for wide promotion and application.

[0034] like Figure 2As shown, in this embodiment, the shell 210 includes a bottom plate 211, a first wall body 212 formed by an edge in the width direction of the bottom plate 211 extending upward and outward, a second wall body 213 formed by the first wall body 212 extending upward, and a third wall body 214 formed by an edge in the length direction of the bottom plate 211 extending upward. The bottom plate 211, the first wall body 212, the second wall body 213 and the third wall body 214 are enclosed to form a storage cavity. The first wall body 212 is rotatably connected to the upper end of the bottom bracket 100, the second wall body 213 and the top of the second wall body 213 are enclosed to form a horizontal discharge port, and the vertical discharge port is opened on the side of the second wall body 213. The first wall body 212 is rotatably connected to the upper end of the bottom bracket 100, the upper end of the first wall body 212 close to the bottom bracket 100 is rotatably connected to the valve 230, and the upper end of the third wall body 214 away from the bottom bracket 100 is rotatably connected to the cover plate 220. Specifically, the volume of the storage cavity mainly depends on the width and length of the bottom plate 211, and the heights of the first wall 212, the second wall 213 and the third wall 214. The first wall 212 formed by extending upward and outward increases the volume in the width direction to a certain extent. When the shell 210 is in a tilted state, the material is unloaded through the inclined surface of the second wall 213 under the action of gravity; the volume can be further increased by the second wall 213, and the second wall 213 is arranged in the vertical direction, which is beneficial to improve the stability of the shell 210 structure and the passability of the box-type cotton picker using the storage device; and the vertical unloading port on the second wall 213 is used to unload the material in coordination with the horizontal unloading port to prevent the material from accumulating on the second wall 213, thereby achieving efficient unloading.

[0035] It should be understood that passability refers to the ability of the box-type cotton picker to pass through structures such as warehouse doors with limited width during movement.

[0036] like Figure 2As shown, in this embodiment, the first linkage assembly 500 includes a first linkage frame 510 hinged to the bottom bracket 100 and a second linkage frame 520 hinged to the first linkage frame 510 and fixedly connected to the cover plate 220, and the hinge point of the first linkage frame 510 and the bottom bracket 100 is located below the hinge point of the first wall 212 and the bottom bracket 100. Specifically, since the hinge point of the first linkage frame 510 and the bottom bracket 100 is located below the hinge point of the first wall 212 and the bottom bracket 100, and the first linkage frame 510 and the second linkage frame 520 are arranged in a downward bending shape, when the driving assembly 400 drives the first wall 212 to rotate relative to the bottom bracket 100, the distance from the connection point between the second linkage frame 520 and the cover plate 220 to the hinge point of the first linkage frame 510 and the bottom bracket 100 increases, and the first linkage frame 510 and the second linkage frame 520 expand outward to drive the cover plate 220 to move outward, so that when the shell 210 is in a tilted state, the linkage cover plate 220 opens the horizontal unloading port.

[0037] In this embodiment, a feed port 1 is provided on the side of the third wall 214, and a feed port 2 for communicating with the feed port 1 is provided on the second linkage frame 520. Specifically, in the initial state, the feed port 1 is connected with the feed port 2, and the harvested materials are sequentially stored in the storage cavity through the feed port 2 and the feed port 1.

[0038] like Figure 3As shown, in this embodiment, the second linkage assembly 600 includes a telescopic assembly 610 that can be telescopically adjusted in length and is hinged to the bottom frame, a first connecting rod 620 that is hinged to the telescopic assembly 610 and the third wall 214 respectively, and a second connecting rod 630 that is hinged to the free end of the valve 230 and the telescopic assembly 610 respectively. Specifically, in the initial state, under the action of gravity, the telescopic assembly 610, the first connecting rod 620 and the second connecting rod 630 move downward, and the angle between the first connecting rod 620 and the second connecting rod 630 becomes smaller, so as to pull the valve 230 to rotate in the direction close to the shell 210, thereby closing the vertical discharge port on the shell 210; when the shell 210 is in a tilted state and the vertical discharge port is arranged downwardly, under the action of gravity, the telescopic assembly 610, the first connecting rod 620 and the second connecting rod 630 move downward, and the angle between the first connecting rod 620 and the second connecting rod 630 becomes larger, so as to make the free end of the valve 230 rotate in the direction away from the second wall 213, thereby opening the shell 210 The vertical cotton unloading port on the shell 210 is provided, and the opening and closing angle of the valve 230 relative to the second wall 213 is appropriate; in the initial state, the valve 230 can automatically close the vertical unloading port under the action of the second linkage assembly 600; and when the shell 210 is in a tilted state, the valve 230 automatically opens the vertical unloading port under the action of closing the second linkage assembly 600, and at this time, the length of the telescopic assembly 610 is minimum, and the opening and closing angle of the valve 230 relative to the second wall 213 during unloading can be increased by increasing the length of the telescopic assembly 610 to ensure that the crops are unloaded smoothly from the cotton unloading port, so that the opening and closing angle of the valve 230 relative to the second wall 213 can be changed within a certain range according to the unloading requirements to ensure the unloading efficiency. It should be understood that if the lengths of the connecting rods in the second linkage assembly 600 are fixed, the components may interfere with each other during assembly, making assembly difficult. However, the present application adjusts the length through the adjustable length telescopic assembly 610, which effectively avoids interference with each other during assembly of the second linkage assembly 600, thereby greatly reducing the difficulty of assembling the second linkage assembly 600.

[0039] like Figure 5As shown, in this embodiment, the telescopic assembly 610 includes a first telescopic rod 611 hinged to the first connecting rod 620 and the second connecting rod 630, respectively, a second telescopic rod 612 hinged to the bottom bracket 100, and an adjustment sleeve 613 threadedly connected to the first telescopic rod 611 and the second telescopic rod 612, respectively, for driving the first telescopic rod 611 and the second telescopic rod 612 to move closer to or away from each other by rotation, and the threads on the first telescopic rod 611 and the second telescopic rod 612 have opposite rotation directions. Specifically, since the first telescopic rod 611 is unable to rotate due to the interference of the bottom frame, and the second telescopic rod 612 is unable to rotate due to the interference of the first connecting rod 620 and the second connecting rod 630, and since the threads on the first telescopic rod 611 and the second telescopic rod 612 have opposite rotation directions, when the adjustment sleeve 613 is rotated, the first telescopic rod 611 and the second telescopic rod 612 are driven to approach each other, thereby reducing the length of the telescopic assembly 610, or the first telescopic rod 611 and the second telescopic rod 612 are driven to move away from each other, thereby increasing the length of the telescopic assembly 610, thereby adjusting the opening and closing angle of the valve 230 relative to the second wall 213.

[0040] like Figure 5 As shown, in this embodiment, a positioning nut 1 614 is threadedly connected on the first telescopic rod 611 and is used to abut against the adjustment sleeve 613 to prevent the first telescopic rod 611 and the second telescopic rod 612 from approaching each other. Specifically, when the positioning nut 1 614 is threadedly connected to the first telescopic rod 611 and abuts against the adjustment sleeve 613, the adjustment sleeve 613 cannot drive the first telescopic rod 611 and the second telescopic rod 612 to approach each other when rotating to reduce the length of the telescopic assembly 610, so that the minimum length of the telescopic assembly 610 is fixed, that is, according to the unloading demand, the opening and closing angle of the valve 230 relative to the second wall 213 is fixed, that is, by ensuring that when the telescopic assembly 610 is at the minimum length, the opening and closing angle of the valve 230 relative to the second wall 213 meets the unloading demand.

[0041] like Figure 5 As shown, in this embodiment, the second telescopic rod 612 is threadedly connected with a second positioning nut 615 for abutting against the adjustment sleeve 613 to prevent the first telescopic rod 611 and the second telescopic rod 612 from approaching each other. Specifically, when the second positioning nut 615 is threadedly connected with the second telescopic rod 612 and abuts against the adjustment sleeve 613, the adjustment sleeve 613 cannot drive the first telescopic rod 611 and the second telescopic rod 612 to approach each other when rotating to reduce the length of the telescopic assembly 610, so that the minimum length of the telescopic assembly 610 is fixed, that is, according to the unloading demand, the opening and closing angle of the valve 230 relative to the second wall 213 is fixed, that is, by ensuring that when the telescopic assembly 610 is at the minimum length, the opening and closing angle of the valve 230 relative to the second wall 213 meets the unloading demand.

[0042] like Figure 3 and Figure 5 As shown, in this embodiment, the material pressing assembly 300 includes a material pressing fixed seat 310 arranged on the third wall 214, a material pressing driving member 320 arranged on the material pressing fixed seat 310, a linkage rod 330 hinged to the driving end of the material pressing driving member 320, a limiting rod 340 fixedly arranged on the third wall 214, and a material pressing plate 350 respectively connected to the linkage rod 330 and the limiting rod 340 for rotating around the limiting rod 340 to compact the material. Specifically, the material pressing driving member 320 is installed through the material pressing fixed seat 310, and the driving end of the material pressing driving member 320 is extended to drive the linkage rod 330 to pull the material pressing plate 350 to rotate around the limiting rod 340, thereby compacting the material or resetting in the opposite direction, and the cycle is repeated to increase the capacity of the box 200. Optionally, the material pressing driving member 320 is one of an oil cylinder, an air cylinder and an electric push rod.

[0043] In this embodiment, the driving component 400 is one of an oil cylinder, an air cylinder and an electric push rod.

[0044] Embodiment 2

[0045] like Figure 6 As shown, the difference between this embodiment and the first embodiment is that the second linkage assembly 600 includes a tension spring 640 connected to the valve 230 at the first end, and an adjusting member arranged on the third wall 214 and connected to the second end of the tension spring 640 for adjusting the elongation of the tension spring 640 relative to the third wall 214. Specifically, when the shell 210 is tilted to unload, under the dual effects of the gravity of the valve 230 and the gravity of the material, the valve 230 flips downward to open the vertical unloading port. At this time, the tension spring 640 is stretched synchronously to cause the tension spring 640 to produce elastic deformation, thereby causing the tension spring 640 to apply a reset elastic force to the valve 23040, and the opening and closing angle of the valve 230 can be changed steplessly according to the unloading amount of the material to improve the unloading efficiency. After the unloading is completed, the tension spring 640 pulls the valve 230 to close the vertical unloading port; the elongation of the tension spring 640 relative to the third wall 214 is adjusted by the adjusting member to reduce or increase the gravity required to open the valve 230, thereby further adjusting the opening and closing angle of the valve 230, and the specific adjustment amount can be adaptively adjusted according to the unloading requirements.

[0046] like Figure 6As shown, in this embodiment, the adjusting member includes a fixing plate 651 fixedly arranged on the third wall 214, an adjusting bolt 652 movably penetrated through the fixing plate 651, an adjusting plate 653 fixedly connected to the first end of the adjusting bolt 652 and connected to the second end of the tension spring 640, and an adjusting nut 654 threadedly connected to the second end of the adjusting bolt 652. Specifically, the adjusting bolt 652 is installed through the fixing plate 651, and then the adjusting plate 653 is connected through the adjusting bolt 652, and then the adjusting plate 653 is connected to the second end of the tension spring 640, and finally the adjusting nut 654 is threadedly connected to the second end of the adjusting bolt 652 to complete the assembly of the adjusting member; during the assembly process, by rotating the adjusting nut 654, the adjusting nut 654 and the adjusting bolt 652 move relative to each other, and the gravity required for opening the valve 230 can be reduced or increased.

[0047] like Figure 6 As shown, in this embodiment, a hook 1 connected to the first end of the tension spring 640 is arranged on the valve 230, and a hook 2 connected to the second end of the tension spring 640 is arranged on the adjustment plate 653, and the hook 1 and the hook 2 are arranged opposite to each other. Specifically, the first end and the second end of the tension spring 640 are connected to the hook 1 and the hook 2 respectively, so as to complete the rapid assembly of the tension spring 640, and the assembly process is simple and maintenance is convenient; that is, when the tension spring 640 is permanently elastically deformed or torn, the tension spring 640 can be quickly replaced.

[0048] It should be understood that the elastic opening and closing valve 230 in this embodiment helps to ensure that the valve 230 moves smoothly and without impact during the closing process, reduces the safety risks of components impacting and colliding with each other, and avoids the risk of the valve 230 crushing materials during the closing process.
