Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly relates to a fresh corn harvester. Background Art

[0002] As a kind of agricultural product with rich nutrition and tender taste, the market demand for fresh corn has been increasing in recent years. However, there are still many problems in the harvesting process of fresh corn. For example, manual harvesting has low efficiency and high cost. The traditional manual harvesting method has a large labor intensity and low efficiency, and with the rising labor cost, the manual harvesting cost is constantly increasing. The mechanization level is low. The existing corn harvesters are mainly for grain corn and cannot meet the high requirements of fresh corn for ear integrity and freshness. The harvesting loss rate is high. Manual harvesting and the existing mechanical harvesting methods are prone to cause ear damage and omission, resulting in a high harvesting loss rate, which restricts the development of the industry.

[0003] At present, there is little research on the mechanical equipment for fresh corn harvesting. The existing equipment is difficult to adapt to the harvesting of fresh corn with different varieties and different planting modes, and is prone to cause ear damage in the processes of ear picking, conveying, etc., and cannot realize the integrated operations of picking, peeling, grading, boxing, etc. of fresh corn. At the same time, there is also a lack of intelligent control systems and it is difficult to achieve precise harvesting and efficient operation.

[0004] In summary, it is necessary to develop a fresh corn harvester that can achieve efficient, low-loss, and intelligent harvesting of fresh corn. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a fresh corn harvesting machine applicable to mountainous or hilly areas, which can improve the harvesting efficiency and reduce the ear damage rate.

[0006] The present invention is realized through the following technical solutions:

[0007] The fresh corn harvester includes a frame, and also includes a flexible ear picking device. The flexible ear picking device includes a flexible clamping and conveying mechanism, a flexible ear removing mechanism, and a root cutting mechanism fixed on the frame. The flexible clamping and conveying mechanism includes a pair of synchronous belts arranged at intervals and clamping and driving the movement of the corn stalks, a plurality of synchronous belt wheels for driving the movement of the synchronous belts, and a first driving mechanism for driving the end synchronous belt wheel. The flexible ear removing mechanism includes a one-way limiting sleeve arranged below the synchronous belt for restricting the movement direction of the corn stalks. The one-way limiting sleeve is a section of cylindrical tube body. A long strip-shaped opening is opened on the tube wall of the cylindrical tube body. A normally closed limiting baffle is rotatably arranged on each side of the long strip-shaped opening. The two limiting baffles form a one-way door for the corn stalks to enter the inner space of the one-way limiting sleeve. An ear picking cutter is arranged below the limiting baffle. The root cutting mechanism includes a first driving motor fixed at the front end of the frame and a disc cutter fixedly connected to the driving motor shaft.

[0008] Furthermore, the flexible ear picking device further includes a row divider mechanism, which includes two symmetrically arranged sprocket boxes with tapered openings. A driving sprocket, a driven sprocket, and ear dividing chain links for connecting and driving the driving sprocket and the driven sprocket are arranged inside the sprocket boxes. The driving sprocket is coaxially driven with the front end synchronous pulley of the flexible clamping and conveying mechanism.

[0009] Furthermore, it further includes a conveying device, which includes a horizontal conveying mechanism and an inclined conveying mechanism. The horizontal conveying mechanism includes a horizontal conveyor belt arranged below the one-way limiting sleeve for receiving corn ears and a second driving mechanism for driving the horizontal conveyor belt to move. The inclined conveying mechanism includes an inclined conveyor belt arranged below the horizontal conveyor belt for receiving corn ears and a third driving mechanism for driving the inclined conveyor belt to move.

[0010] Furthermore, it further includes a transmission mechanism, which includes a second driving motor arranged behind the frame and a driving shaft driven and connected through a reduction belt. A driving pulley a for drivingly connecting with the first driving mechanism, a driving pulley b for connecting with the second driving mechanism, and a driving sprocket for drivingly connecting with the third driving mechanism are arranged on the driving shaft.

[0011] Furthermore, the first driving mechanism includes a first driving shaft drivingly connected with the driving pulley a, a first bevel gear fixed on the first driving shaft, and a first mating bevel gear meshing with the first bevel gear. The first mating bevel gear shaft is coaxially fixed with the end synchronous pulley. Two pairs of the first bevel gear and the first mating bevel gear are provided, and the module and the number of teeth are opposite to each other, and are used to drive the synchronous belts on their respective same sides.

[0012] Furthermore, the second driving mechanism includes a horizontal conveyor belt pulley, a second driving shaft drivingly connected with the driving pulley b, a second bevel gear fixed on the second driving shaft, and a second mating bevel gear meshing with the second bevel gear. The second mating bevel gear shaft is coaxially fixed with the horizontal conveyor belt pulley.

[0013] Furthermore, the third driving mechanism includes a pair of driven sprockets driven by a chain with the driving sprocket, and the inclined conveyor belt is fixed on the chain.

[0014] Furthermore, rotating shafts are fixedly arranged on both sides of the long strip-shaped opening. A rotating shaft hole is arranged on the limit baffle, and a return spring for resetting the limit baffle to the normally closed state is arranged on the rotating shaft.

[0015] Furthermore, guiding baffles are also arranged on the two outer sides of the one-way limiting sleeve.

[0016] Furthermore, a curved ear guiding plate is arranged at the connection part of the horizontal conveyor belt and the inclined conveyor belt.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The flexible ear picking device adopted by the present invention can gently pick the ears of corn through its bionic design picking device, effectively reducing the ear damage rate and ensuring the integrity of the ear appearance;

[0019] 2. For the driving part of the flexible clamping and conveying mechanism adopted by the present invention, coaxial bevel gears are used for driving. The synchronous pulley shafts at the ends of the two synchronous belts are connected to bevel gears with the same module and number of teeth, which are connected to another pair of coaxial bevel gears, ensuring that the linear speeds of the two synchronous belts are the same, so that the tangential forces received by the corn stalks during the clamping and conveying process are basically equal in magnitude and opposite in direction, thereby reducing the rotational movement of the stalks during the conveying process.

[0020] 3. The flexible conveying device of the present invention avoids the collision damage of the ears of corn during transportation and improves the freshness of the ears of corn.

[0021] 4. The present invention adjusts the height through the lifting of the flexible clamping and conveying mechanism, thereby adjusting the space height when the front end of the synchronous belt contacts the corn stalks, adapting to the use of different corn stalk heights, and thus improving the adaptability.

[0022] 5. The present invention simultaneously drives the first driving mechanism, the second driving mechanism and the third driving mechanism with the same driving motor, simplifies the structure, and reduces the equipment cost and usage cost.

[0023] In summary, the present invention integrates functions such as picking, conveying, and collecting, realizes the mechanized operation of fresh corn harvesting, greatly improves the production efficiency, and reduces the labor cost. At the same time, by adopting a crawler chassis and a simple mechanical structure, the volume and weight of the fresh corn harvester are greatly reduced, the field passability is improved, and the requirements of the current situation of corn planting in mountainous and scattered areas in the southwestern region for harvesting machinery are met. That is, this equipment is applicable to mountainous or hilly areas, improves the harvesting efficiency and reduces the ear damage rate. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0039] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0040] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0041] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side" and "the other side" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is customarily placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0042] In addition, terms such as "same" do not mean that the components must be absolutely the same, but there may be slight differences. The term "vertical" only means that the positional relationship between components is relatively more vertical compared to "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0043] As Figures 1 to 12 shown, the fresh corn harvester of this embodiment includes a frame 1 and a crawler chassis 2 fixed below the frame. Specifically, this embodiment further includes a flexible ear picking device, which specifically includes a flexible clamping and conveying mechanism 3, a flexible ear removing mechanism 4 and a root cutting mechanism 5 fixed on the frame. Specifically:

[0044] The flexible clamping and conveying mechanism includes a pair of synchronous belts 6 arranged at intervals and clamping and driving the movement of the corn stalks, a plurality of synchronous belt wheels 7 for driving the synchronous belts to move, and a first driving mechanism 8 for driving the end synchronous belt wheel. The heads of the corn stalks are clamped between the two synchronous belts. The first driving mechanism rotates and drives, and the synchronous belts move horizontally, thereby driving the horizontal movement of the corn stalks;

[0045] The flexible ear - removing mechanism includes a one - way limiting sleeve 9 arranged below the synchronous belt for restricting the movement direction of the corn stalk. The one - way limiting sleeve is a section of cylindrical pipe body. A long - strip opening is formed on the pipe wall of the cylindrical pipe body. On both sides of the long - strip opening, a normally - closed limiting baffle 10 is rotatably arranged. The two limiting baffles form a one - way door for the corn stalk to enter the inner space of the one - way limiting sleeve. An ear - removing cutter 11 is arranged below the limiting baffle. As the corn stalk moves horizontally, the corn stalk enters the one - way limiting sleeve through the one - way door. And as the corn stalk moves upward, the corn ear is cut off from the corn stalk by the ear - removing cutter, specifically as Figure 12 shown;

[0046] The root - cutting mechanism includes a first driving motor 12 fixed at the front end of the frame and a disc cutter 13 fixedly connected to the driving motor shaft. The disc cutter adopts a detachable blade type, and the blades are evenly distributed on the outer edge of the disc, so as to ensure the rapid and effective cutting of the corn stalk;

[0047] As an improvement of this embodiment, the flexible ear - picking device further includes a dividing mechanism 14. The dividing mechanism includes two symmetrically arranged sprocket boxes 15 with tapered openings. A driving sprocket 16, a driven sprocket 17 and a dividing chain link 18 for connecting and driving the driving sprocket and the driven sprocket are arranged in the sprocket box. The driving sprocket is coaxially driven with the synchronous belt pulley at the front end of the flexible clamping and conveying mechanism. Through the synchronous belt pulley, the simultaneous driving of the dividing mechanism can be realized, reducing the driving mechanism and simplifying the device. The sprocket box with a tapered opening is conducive to the entry of the corn stalk and is restricted in the space between the two sprocket boxes. Through the rotation of the dividing chain link, the upper part of the corn stalk and the leaves are quickly conveyed into the flexible clamping and conveying mechanism, which can effectively reduce the lodging situation caused by the non - perpendicular growth of the corn stalk in the vertical direction during the harvesting process.

[0048] Particularly, a tooth - pulling device 46 is arranged outside the dividing chain link, which can drive the separation of the corn stalk and leaves located inside the sprocket box, so as to enter along the tapered opening and finally enter the conveying channel between the synchronous belts.

[0049] As an improvement of this embodiment, a conveying device is further included. The conveying device includes a horizontal conveying mechanism 19 and an inclined conveying mechanism 20. The horizontal conveying mechanism includes a horizontal conveyor belt 21 arranged below the one - way limiting sleeve for receiving the corn ear and a second driving mechanism 22 for driving the horizontal conveyor belt to move. The inclined conveying mechanism includes an inclined conveyor belt 23 arranged below the horizontal conveyor belt for receiving the corn ear and a third driving mechanism 24 for driving the inclined conveyor belt to move. The corn ear is received below the one - way limiting sleeve, moves horizontally through the horizontal conveyor belt and enters the inclined conveyor belt. The inclined conveyor belt has an upward slope, so as to drive the corn ear to be conveyed upward, thus facilitating the packing and collection at a certain height.

[0050] As an improvement of this embodiment, it further includes a transmission mechanism 25. The transmission mechanism includes a second driving motor 26 arranged at the rear of the frame and a driving shaft 28 driven and connected through a speed reducer belt 27. A driving pulley a29 drivingly connected to the first driving mechanism, a driving pulley b30 connected to the second driving mechanism, and a driving sprocket c31 drivingly connected to the third driving mechanism are arranged on the driving shaft. By using one driving motor to simultaneously drive the three mechanisms, the structure is simplified and the cost is reduced.

[0051] As an improvement of this embodiment, the first driving mechanism includes a first driving shaft 32 drivingly connected to the driving pulley a, a first bevel gear 33 fixed on the first driving shaft, and a first mating bevel gear 34 meshing with the first bevel gear. The first mating bevel gear shaft is coaxially fixed with the end synchronous pulley. Two pairs of the first bevel gear and the first mating bevel gear are provided, and the module and the number of teeth are relative. Each pair drives the synchronous belt on the same side, so as to ensure that the linear speeds of the synchronous belts on both sides are the same, so that the tangential forces received by the corn stalks during the clamping and conveying process are basically equal in magnitude and opposite in direction, thereby reducing the rotational movement of the stalks during the conveying process.

[0052] As an improvement of this embodiment, the second driving mechanism includes a horizontal conveyor pulley 35, a second driving shaft 36 drivingly connected to the driving pulley b, a second bevel gear 37 fixed on the second driving shaft, and a second mating bevel gear 38 meshing with the second bevel gear. The second mating bevel gear shaft is coaxially fixed with the horizontal conveyor pulley to achieve power sharing.

[0053] As an improvement of this embodiment, the third driving mechanism includes a pair of driven sprockets 39 driven by a chain with the driving sprocket, and the inclined conveyor belt is fixed on the chain.

[0054] As an improvement of this embodiment, rotating shafts 40 are fixedly arranged on both sides of the long strip-shaped opening. A rotating shaft hole is arranged on the limit baffle, and a return spring 41 for resetting the limit baffle to the normally closed state is arranged on the rotating shaft, so as to achieve the normally closed state. When the corn stalk squeezes the limit baffle, the return spring is pressed inward. At this time, the distance between the two symmetrically arranged limit baffles gradually increases until the distance is greater than the diameter of the corn stalk, and the corn stalk completely enters the one-way limit sleeve. The squeezing force of the corn stalk on the limit baffle disappears, and it returns to the initial position under the elastic force of the return spring, ensuring that the corn stalk can only move along the axial direction of the sleeve inside the one-way limit sleeve at this time, which is beneficial to restricting the corn stalk in the one-way limit sleeve and making the ear picking operation stable and reliable.

[0055] As an improvement of this embodiment, guiding baffles 42 are further arranged on the outer side of the long strip-shaped opening of the one-way limit sleeve. The two guiding baffles extend outwards. Since a larger intercepting space is formed, it is beneficial to guide the corn stalks that deviate further into the one-way limit sleeve, further ensuring the ear picking operation.

[0056] As a further improvement of this embodiment, a support frame 43 is further provided in this embodiment. A support block 44 for fixing the guiding baffle is provided on the support frame. A threaded hole is provided on the support block, and a threaded through-hole is provided on the guiding baffle. Screws pass through the threaded through-hole and enter the threaded hole to fix the guiding baffle.

[0057] As an improvement of this embodiment, grooves are provided on the surfaces of the synchronous belt and the conveyor belt, and the depth of the grooves is 0.25 - 0.5 mm.

[0058] As an improvement of this embodiment, a height adjustment mechanism 45 is further provided in this embodiment. It includes a reciprocating lead screw, a lead screw nut, and a lead screw fixing plate. The reciprocating lead screw is fixed below the flexible clamping mechanism through the lead screw fixing plate. The lead screw nut can move vertically along the reciprocating lead screw to achieve height adjustment.

[0059] When harvesting fresh corn, the operator moves the harvester forward after aligning it with the rows. The upper end of the corn stalk first enters the divider, and under the guidance of the divider, it enters the flexible clamping and conveying mechanism and is fixed in the horizontal direction. At this time, as the harvester moves forward and the clamping and conveying mechanism is fixed, the root cutting mechanism located below contacts the root of the corn stalk, and the root cutting work is completed through the disc cutter. At this time, the corn stalk with the corn ear gradually enters the flexible ear-picking mechanism in the axial direction of the harvester under the conveying of the clamping and conveying mechanism. Under the action of the limit baffle, the stalk below the corn ear enters the one-way limit sleeve. Under the combined action of the flexible clamping and conveying mechanism and the one-way limit sleeve, the corn stalk moves upward along the axial direction of the sleeve. During the upward movement, the connection between the corn ear and the stalk gradually approaches the ear-picking cutter located below the sleeve. After contact, the ear-picking work is completed. The corn ear separated from the stalk falls onto the horizontal conveying mechanism and enters the inclined conveying mechanism through the ear guide plate and is boxed, completing the fresh corn harvesting task.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
