Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a mobile, ground-based cotton cleaning device. Background Technology

[0002] Cotton is an important economic crop in my country. During harvest, cotton harvesters are widely used. However, because cotton is light, cotton harvesters cannot collect all the cotton on the plant. Some cotton is missed and falls to the ground due to the impact of the harvester. This is called "fallen cotton". Small cotton fields can collect these fallen cotton by picking them up manually, while large cotton fields need to rely on machinery for collection.

[0003] The existing technology for collecting fallen cotton has the following drawbacks in the process: 1. The collected cotton leaves often contain a lot of impurities such as stems, leaves or cotton husks. Existing machinery often collects them all and then cleans them separately, which is not very efficient.

[0004] 2. The existing machinery is equipped with collection components that need to extend into the soil during operation. Therefore, the surface of the components may be covered with sticky soil, and debris such as cotton leaves and stalks on the ground can easily get embedded in the collection components, affecting their normal operation.

[0005] To address the above issues, a new device for collecting cotton that has fallen to the ground needs to be designed. Utility Model Content

[0006] The purpose of this invention is to provide a mobile, ground-based cotton cleaning device, which aims to solve the problem of insufficient working efficiency of existing ground-based cotton collection devices.

[0007] To solve the above problems, the present invention adopts the following technical solution: A portable, floor-mounted cotton cleaning device, mounted on a vehicle, includes: The picking mechanism includes a picking roller, which is connected to the vehicle's power system. Multiple picking rods are arranged along the circumference of the picking roller. The free ends of the picking rods are curved and configured to contact the ground. The picking rods pick up the fallen cotton as the picking roller rotates and throw it out in the direction of rotation. A conveying mechanism is arranged downstream of and connected to the picking mechanism. The conveying mechanism has multiple conveying rollers, which are connected to the vehicle's power system. The multiple conveying rollers are arranged parallel to the picking rollers. Each conveying roller has multiple sets of spikes on its circumference. The spikes on adjacent conveying rollers are arranged in an interlocking manner to catch the fallen cotton and transport it away from the picking mechanism. A collection mechanism is arranged downstream of and connected to the conveying mechanism.

[0008] The beneficial effects of this utility model are as follows: by utilizing the rotational motion of the pickup roller, the pickup rod is driven to hook the fallen cotton on the ground and throw it backward in accordance with the arc of its end, which reduces the overall contact between the pickup component and the ground and to a certain extent prevents soil from getting stuck in the pickup component. The transportation mechanism adopts a technical solution of conveying rollers and spikes, which can effectively break up large rod-shaped or shell-shaped debris during transportation and let them fall along the roller gap, while the fallen cotton is stuck on the spikes. When the spikes on two adjacent conveying rollers engage, the transfer of the fallen cotton is completed.

[0009] Furthermore, the pickup rod includes a rod body and a mounting base. The mounting base is fixedly connected to the roller body of the pickup roller, and a mounting cavity is formed along the radial direction of the pickup roller. The mounting end of the rod body is connected to the bottom of the mounting cavity through a spring.

[0010] A further beneficial effect of this utility model is that the rod is movably connected in the mounting base by the spring, which can buffer the rod when it contacts the ground.

[0011] Furthermore, the picking mechanism also includes a cleaning roller, which is mounted on the side of the picking roller away from the conveying mechanism. Multiple sets of striking bars are arranged along the circumference of the cleaning roller, and the multiple sets of striking bars are interlocked with multiple sets of picking rods. The direction of rotation of the cleaning roller is opposite to that of the picking roller.

[0012] A further beneficial effect of this invention is that the separately designed cleaning roller and striking bar can remove mud, cotton husks, and other debris stuck between the pickup rods.

[0013] Furthermore, it also includes a gathering roller, which is arranged between and parallel to the pickup roller and the first conveying roller. The gathering roller is divided into two equal sections along its axial direction, and each section has blades spirally mounted on its outer periphery, with the two sections having opposite directions of rotation of the blades.

[0014] A further beneficial effect of this utility model is that by setting a gathering roller, the length of the conveying roller is not limited by the picking roller, which can effectively reduce the length of the conveying roller and reduce the space occupied by the conveying mechanism, while the length of the picking roller is not affected.

[0015] Furthermore, the multiple conveying rollers have the same roller diameter, and the number of spike groups on the conveying rollers increases along the direction away from the pick-up roller.

[0016] A further beneficial effect of this invention is that as the number of spikes increases, the crushing effect is better, and large impurities are gradually crushed during the entire transportation process.

[0017] Furthermore, the plurality of conveying rollers are raised sequentially in a direction away from the pick-up roller.

[0018] A further beneficial effect of this utility model is that it facilitates connection to downstream collection mechanisms.

[0019] Furthermore, the conveying mechanism also includes a support plate, which is arranged below the plurality of conveying rollers. The support plate has an arc corresponding to each of the conveying rollers and has grid holes.

[0020] A further beneficial effect of this utility model is that the support plate can catch small cotton particles that leak from the roller gap, and the broken impurities can also leak out through the grid holes and will not remain on the support plate.

[0021] Furthermore, the collecting mechanism includes a cotton collecting box, a fan, and a feed pipe. The fan is installed inside the cotton collecting box, and one end of the feed pipe is connected to the cotton collecting box, while the other end is a feed inlet that connects to the conveying end of the conveying mechanism.

[0022] A further beneficial effect of this utility model is that it uses a fan and a feed pipe to collect the fallen cotton into a cotton collection box.

[0023] Furthermore, the feed inlet of the feed pipe is configured as a funnel-shaped opening.

[0024] A further beneficial effect of this invention is that the trumpet-shaped opening can increase the suction area while increasing the diameter of the feed pipe, thus ensuring the wind speed while simultaneously absorbing more fallen cotton.

[0025] Furthermore, the collection mechanism also includes a dust collection bag and a dust collection fan. A dust removal port is opened on the side wall of the feed pipe near the cotton collection box. The dust collection bag is connected to the dust removal port, and the dust collection fan is installed at the dust removal port of the feed pipe.

[0026] A further beneficial effect of this utility model is that by setting up a dust collection bag and a dust collection fan, the collected cotton that has fallen to the ground can be subjected to preliminary dust removal treatment. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As shown in the figure, this utility model provides a mobile ground cotton cleaning device, which consists of a main cleaning device and a vehicle. The cleaning device is mounted on the vehicle. Here, the vehicle generally refers to mobile agricultural equipment, such as tractors. The power system and transmission system of such equipment are configured to be suitable for installing various agricultural tools that require additional power, such as harvesting and sowing. This part is a conventional technical means in this field.

[0032] Specifically, the cleaning device includes a pickup mechanism, which includes a pickup roller 1. The pickup roller 1 is mounted at the front of the vehicle via a shaft-like structure and is connected to the vehicle's power system via a belt or similar structure. This allows the pickup roller 1 to rotate synchronously as the vehicle moves forward, with the rotation direction opposite to that of the wheels. Multiple pickup rods 110 are arranged along the circumference of the pickup roller 1. Here, a set of pickup rods 110 refers to a row of pickup rods 110 along the axial direction of the pickup roller 1. These pickup rods 110 are configured to be in contact with the ground. This means that the length of the pickup rod 110 itself can contact the ground, or that the pickup roller 1 can move up and down via a hydraulic structure to ensure that the pickup rods 110 can contact the ground. As the pickup roller 1 rotates, the pickup rods 110 pick up the fallen cotton and throw it out in the direction of rotation. The pickup method depends on the specific structure of the pickup rod 110. The end of the pickup rod 110 can be straight, curved, needle-shaped, or scraper-shaped.

[0033] The conveying mechanism is located downstream of and connected to the picking mechanism. "Downstream" here can be understood as the rear of the picking mechanism. Due to collection needs, the picking mechanism in front must throw the picked-up cotton backwards. The conveying mechanism has multiple conveying rollers 2, which are also mounted on the vehicle via shafts and other structures, and are connected to the vehicle's power system via transmission belts and other transmission structures. The multiple conveying rollers 2 are arranged parallel to the picking rollers 1. Each conveying roller 2 has multiple sets of spikes 210 along its circumference on its surface. The spikes 210 on adjacent conveying rollers 2 are interlocked and staggered to receive the cotton and transport it away from the picking mechanism. The conveying mechanism uses a technical solution of conveying rollers 2 and spikes 210, which can effectively break up large rod-shaped or shell-shaped debris during transportation and allow it to fall along the roller gaps. The cotton is then stuck to the spikes 210. When the spikes 210 on two adjacent conveying rollers 2 engage, the transfer of the cotton is completed.

[0034] There is also a collection mechanism, which is located downstream of and connected to the conveying mechanism. "Downstream" here should be understood as the area behind the conveying mechanism, away from the picking mechanism, where the collection mechanism connects and collects the transported cotton that has fallen to the ground.

[0035] It should be noted that the main inventive point of this application lies in the picking function of the pickup roller 1 and the pickup rod 110, as well as the cooperation of the multiple conveying rollers 2. The subsequent description mainly focuses on the structure or other features of the pickup roller 1 and the conveying rollers 2. Some other structures appearing in the overall device, such as the front cover, the tractor wheels, cab, main shaft, etc., are common knowledge and have not been described in detail. As for some structures used by the tractor to drive the various rollers, such as the engine, transmission system, and belts used to drive the various rollers, their connection and transmission methods are all conventional technical means in the art and are well known to those skilled in the art. The part about how to use a tractor to drive the rotating parts mounted on the tractor is not the inventive point of this application, so it has been omitted in the description and drawings. It should be understood that the movable cotton cleaning device provided by this application includes the content described in the specification of this application, which belongs to the inventive point of this application, as well as the content that is not shown in the specification and drawings but is likely or should be in the overall structure of this application, which is the common knowledge in the art. Omitting this part does not affect the integrity of this application and will not cause problems for those skilled in the art to not understand the technical solution of this application.

[0036] In another embodiment of this utility model, each pickup rod 110 includes a rod body 111 and a mounting base 112. The mounting base 112 can be welded or bolted to the roller body of the pickup roller 1. An installation cavity is opened along the radial direction of the pickup roller 1. The mounting end of the rod body 111 is connected to the bottom of the mounting cavity through a spring. In this embodiment, the rod body 111 is movably connected to the mounting base 112 through the spring. When the rod body 111 contacts the ground, the rod body 111 can be buffered.

[0037] In another embodiment of this utility model, the picking mechanism also includes a cleaning roller 3. The cleaning roller 3 is also mounted on the side of the picking roller 1 away from the conveying mechanism by a structure with the same properties as the shaft frame. In order to avoid interfering with the normal picking of cotton, specifically at the front and top, the cleaning roller 3 is also driven by the vehicle's power system. Multiple sets of striking strips 310 are arranged along its circumference. The multiple sets of striking strips 310 and multiple sets of picking rods 110 are arranged in an interlocking manner. In order to achieve a better cleaning effect, the direction of the cleaning roller 3 is opposite to that of the picking roller 1. In this embodiment, by using the separately set cleaning roller 3 and striking strips 310, mud or cotton shells and other debris stuck between the picking rods 110 can be cleaned away.

[0038] In another embodiment of this utility model, a gathering roller 4 is also included. The gathering roller 4 is arranged between and parallel to the pickup roller 1 and the first conveying roller 2. Its assembly and driving method is similar to other rotating parts of this application. The gathering roller 4 is divided into two equal sections along its axial direction. Each section is equipped with a helical blade 410 on its outer periphery, and the two helical blades 410 rotate in opposite directions. In this embodiment, by setting the gathering roller 4, the length of the conveying roller 2 is not limited by the pickup roller 1, which can effectively reduce the length of the conveying roller 2 and reduce the space occupied by the conveying mechanism, while the length of the pickup roller 1 is not affected.

[0039] In another embodiment of this utility model, the multiple conveying rollers 2 have the same roller diameter, and the number of spikes 210 on the conveying rollers 2 increases along the direction away from the pickup roller 1. According to the accompanying drawings of this application, there are four conveying rollers 2 in this embodiment, and the number of spikes 210 on the four conveying rollers 2 are 6, 8, 10 and 12 respectively. In this embodiment, as the number of spikes 210 increases, the crushing effect is better, and large impurities are gradually crushed during the entire transportation process.

[0040] In another embodiment of this utility model, a plurality of conveying rollers 2 are raised sequentially in a direction away from the pickup roller 1. In this embodiment, the above-mentioned arrangement facilitates connection to the downstream collection mechanism.

[0041] In another embodiment of this utility model, the conveying mechanism further includes a support plate 5, which is specifically arranged below multiple conveying rollers 2 and is directly welded or bolted to the tractor through a structure of the same attributes as the bracket. The support plate 5 has an arc corresponding to each conveying roller 2 and has grid holes 510. In this embodiment, the support plate 5 can catch small cotton particles that leak from the roller gap, and broken impurities can also leak out from the grid holes 510 and will not remain on the support plate 5.

[0042] In another embodiment of this utility model, the collection mechanism includes a cotton collection box 6, a blower (not shown), and a feed pipe 7. The cotton collection box 6 is fixed to the rear of the tractor. The blower is installed inside the cotton collection box 6. The blower is common knowledge technology and is not shown, but this does not affect those skilled in the art to understand the technical solution of this application, or how the blower is assembled and operated. One end of the feed pipe 7 is connected to the cotton collection box 6, and the other end is a feed inlet that connects to the conveying end of the conveying mechanism. The blower and the feed pipe 7 are used to collect the fallen cotton into the cotton collection box 6.

[0043] In another embodiment of this utility model, the feed inlet of the feed pipe 7 is configured as a trumpet-shaped opening. The trumpet-shaped opening can increase the suction area while increasing the diameter of the feed pipe 7, so as to ensure the wind speed and simultaneously suck up more fallen cotton.

[0044] In another embodiment of this utility model, the collection device further includes a dust collection bag and a dust collection fan (not shown). The dust collection bag and the dust collection fan are common knowledge technologies, and their omission does not affect the understanding of the technical solution of this application by those skilled in the art.
