Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to an auxiliary device for peanut harvesters that allows for adjustable peanut dropping positions and turning and drying of peanuts. Background Technology

[0002] Peanut harvesting requires the use of peanut harvesters to improve harvesting efficiency. However, both domestic and foreign peanut harvesters have certain drawbacks. Domestic peanut harvesters dig out the peanuts, shake off the soil with a chain, and send them to the back. The peanut vines are left scattered on the ground. This makes it difficult to dry the peanuts. They need to be turned over and dried manually later, which is time-consuming, labor-intensive, and relatively expensive.

[0003] Foreign peanut harvesters involve digging, shaking off the soil with a chain, and then placing the peanuts. The difference between foreign and domestic peanut harvesters is the addition of a turning mechanism, which can turn the peanuts face up and arrange them in a line on the ground. Currently, some domestic manufacturers are imitating foreign technology by adding a turning mechanism to the tail end of the peanut harvester. However, the current turning device cannot adjust the landing position of the peanuts, and the turned peanuts are arranged in a line on the ground, resulting in a relatively small drying area and low drying efficiency. Furthermore, the current turning device requires power to assist in turning and arranging the peanuts.

[0004] Therefore, how to provide a peanut harvester auxiliary device that can adjust the position of the peanuts, increase the drying area, improve the drying efficiency, and does not require power to turn the peanuts is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides an auxiliary device for peanut harvesters with adjustable dropping position and turning and drying function, which can change the dropping position and turn the peanuts face up on the ground to facilitate drying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for a peanut harvester with adjustable fruit dropping position and fruit turning and drying, installed at the discharge end of the peanut harvester, comprising:

[0007] A connecting square tube is provided, which can be detachably connected to the rear end of the frame of the peanut harvester and whose installation position on the frame can be adjusted.

[0008] The swing frame is rotatably connected to the end of the connecting square tube away from the frame. The bottom of the swing frame is rotatably connected to a receiving cylinder. The receiving cylinder is located on the path of peanut falling and temporarily slows down the falling peanut fruit. Under the action of the law of equilibrium, the peanut vine continues to move down to complete the deflection and turning of the falling fruit. The receiving cylinder rotates under the eccentric gravity generated by the continuous falling of the fruit.

[0009] Tail plate, which is offset above and to the side of the receiving drum, blocks the material from flying out. The offset gravity of the tail plate causes the receiving drum to deflect to one side of the frame. The receiving drum swings backward adaptively according to the amount of peanuts falling and speeds up the falling speed.

[0010] The adjustable side plate has two sets and is respectively connected to both sides of the discharge end of the frame. The adjustable side plate is located above the receiving drum. The adjustable side plate guides the material falling from the discharge end to the receiving drum. The adjustable side plate controls the position of the falling material on the receiving drum. A gathering rod is movably provided at the bottom of the adjustable side plate and in front of the receiving drum. The gathering rod swings back and forth to avoid material snagging.

[0011] The beneficial effects of this invention are: the connecting square tube adjusts the installation position of the auxiliary device on the frame according to the specific situation during peanut harvesting, effectively avoiding material blockage. The peanut vines and peanuts at the harvester's discharge end first pass through the adjusting side plate and slide down onto the receiving drum under the guide of the adjusting side plate. The peanut fruit is relatively heavier than the peanut vine. Since the receiving drum catches the peanut fruit first, it plays a brief catching role. At this time, the peanut vine continues to fall according to the law of equilibrium. During this process, deflection occurs. Under the continuous falling action, the eccentric gravity generated by the falling material on the receiving drum will cause the receiving drum to rotate, completing the turning of the peanut and detaching it from the receiving drum. This process does not require external power, which optimizes the overall structural space on the one hand, and on the other hand... This device can reduce fuel consumption and lower harvesting costs. In addition, adjusting the side plate directly adjusts the peanut landing position on the receiving drum, increasing the drying area and allowing for thinner spreading. Due to the offset effect of the tail plate, the receiving drum is tilted to one side of the frame. When there is too much material falling, the receiving drum can adaptively swing backward to increase the material falling speed. The receiving drum can swing to a vertical position, and the gathering rod can restrain the peanut falling outward. Since the gathering rod can swing back and forth, during the movement of the entire device, if the gathering rod comes into contact with obstacles on the ground, it will cause the gathering rod to swing backward, which can also prevent the gathering rod from getting stuck with material. The gathering rod automatically resets under the action of the return spring. This device has a simple structure and relies on its own structural characteristics to turn the peanuts, making them easier to dry.

[0012] Preferably, the discharge end of the frame is provided with insertion interfaces on both sides, there are two connecting square tubes and they are respectively inserted into the corresponding insertion interfaces, the top of the swing frame is provided with a rod sleeve, and the two connecting square tubes are provided with a crossbar on their adjacent side walls, and the rod sleeve is rotatably connected to the crossbar.

[0013] The resulting technical effect is that by connecting the square tube, the auxiliary device of the peanut harvester can be installed with the frame, and the distance between the rotating drum and the frame can be adjusted to change the material dropping effect and prevent material blockage.

[0014] Preferably, both ends of the tail plate are provided with connecting rods, the connecting rods are hinged to the bottom end of the swing frame, and a tension spring is provided between the connecting rods and the swing frame to hold the tail plate.

[0015] The resulting technical effect is that the tailplate is held in place by a tension spring, achieving an offset connection between the tailplate and the rotating drum. Due to the weight of the tailplate itself, the forward deflection position of the rotating drum can also be adjusted.

[0016] Preferably, the top of the sleeve is connected to a telescopic adjusting screw, the free end of which abuts against the tail plate and adjusts the offset angle between the tail plate and the rotating cylinder.

[0017] The resulting technical effect is that the telescopic adjustment screw can adjust the offset angle between the tail plate and the receiving drum. Since the tension spring holds the swing frame and the connecting rod, it ensures the balance and stability of the tail plate and the receiving drum. By adjusting the relative angle between the tail plate and the receiving drum, the offset gravity of the tail plate can be changed, and the forward swing angle of the receiving drum under static conditions can be adjusted.

[0018] Preferably, the receiving drum is located below the end of the conveyor chain to receive the falling peanuts. The receiving drum has discs at both ends, and the discs are connected to the swing frame shafts on the corresponding sides. Multiple rollers are arranged circumferentially on the receiving drum and between corresponding discs. The outer periphery of the multiple rollers is wrapped with elastic cloth. When the peanuts fall onto the elastic cloth between two adjacent rollers, they undergo elastic deformation. The soil on the peanuts is bounced off by the elastic cloth during the rotation of the receiving drum.

[0019] The resulting technical effect is that the elastic cloth deforms to a certain extent when the material is dropped, blocking the peanuts. The peanut vines continue to fall according to the law of balance, at which point they will deflect and turn over. When enough material is dropped, the eccentric gravity of the peanuts and vines will cause the receiving drum to rotate, and the peanuts and vines will separate from the receiving drum, thus turning and placing the peanuts for easy drying. The soil on the elastic cloth can also be shaken off.

[0020] Preferably, the machine frame is provided with side plate adjustment frames on both sides of the discharge end. The side plate adjustment frames change the front-to-back position and the up-to-down position of the adjustment side plate. The adjustment side plate is located above the receiving drum. The adjustment side plate changes the drop position of the fruit on the receiving drum by adjusting the tilt angle.

[0021] The resulting technical effect is that the side plate adjustment frame can change the front-to-back and up-to-down position of the side plate, and the angle adjustment of the side plate can change the position of the peanuts falling on the receiving drum, increasing the spreading area and facilitating drying.

[0022] Preferably, the top of the arm is provided with a movable head, and the bottom of the adjusting side plate near the frame is provided with a movable seat. The movable head is rotatably connected in the movable seat and realizes the back-and-forth swing of the arm. The top of the arm is provided with a return spring, and the arm automatically returns to its original position under the action of the return spring.

[0023] The resulting technical effects are: the guide rod can restrain the falling material and prevent it from running outward. Since the guide rod can be adjusted back and forth and can automatically reset under the action of the return spring, when the device moves, the guide rod will swing backward adaptively when it encounters an obstacle at the bottom to avoid snagging the material. It will automatically reset after there is no obstacle affecting it. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] See the appendix of this invention. Figures 1 to 4 According to an embodiment of the present invention, an auxiliary device for a peanut harvester with adjustable peanut dropping position and peanut turning and drying is installed at the discharge end of the peanut harvester, and includes:

[0031] The connecting square tube 10 is detachably connected to the rear end of the frame of the peanut harvester and its installation position on the frame can be adjusted.

[0032] The swing frame 3 is rotatably connected to the end of the connecting square tube 10 away from the frame 1. The bottom of the swing frame 3 is rotatably connected to the receiving cylinder 4. The receiving cylinder 4 is located on the path of peanut falling and temporarily slows down the falling peanut fruit. Under the action of the balance law, the peanut vine continues to move down to complete the deflection and turning of the falling fruit. The receiving cylinder 4 rotates under the eccentric gravity generated by the continuous falling of the fruit, so that the peanut fruit and peanut vine are separated from the receiving cylinder.

[0033] Tail plate 5 is offset above and to the side of the receiving drum 4. Tail plate 5 blocks the material from flying out. The offset gravity of tail plate 5 causes the receiving drum 4 to deflect to one side of the frame. The receiving drum 4 swings backward adaptively according to the amount of peanuts falling and speeds up the falling speed.

[0034] Adjustable side plate 8, there are two sets of adjustable side plates 8 and they are respectively connected to both sides of the discharge end 102 of the frame 1. The adjustable side plate is located above the receiving drum 4. The adjustable side plate 8 guides the material falling from the discharge end to the receiving drum 4. The adjustable side plate 8 controls the position of the falling material on the receiving drum 4. At the bottom of the adjustable side plate 8 and in front of the receiving drum 4, there is a movable gathering rod 9. The gathering rod 9 swings back and forth to avoid the material getting stuck.

[0035] In other embodiments, the discharge end 102 of the frame 1 is provided with insertion interfaces on both sides, and there are two connecting square tubes 10, which are respectively inserted into the corresponding insertion interfaces. The top of the swing frame 3 is provided with a rod sleeve, and a horizontal bar is provided on the side wall of the two connecting square tubes 10 that are close to each other. The rod sleeve is rotatably connected to the horizontal bar, so that the rotating drum has the ability to swing back and forth.

[0036] In some other specific embodiments, a telescopic adjusting screw 11 is connected to the top of the sleeve. The free end of the telescopic adjusting screw 11 abuts against the tail plate 5 and adjusts the offset angle between the tail plate 5 and the receiving drum 4. When the receiving drum swings downward due to excessive material falling, the tail plate swings accordingly. This process can accelerate the falling of material. The tail plate blocks the peanut vines flying out of the discharge end and guides them to the receiving drum. More and more material falls on the receiving drum until the eccentric gravity causes the receiving drum to rotate. This process does not require additional auxiliary power, reduces the arrangement of the power structure, optimizes the structural space layout, reduces fuel consumption, and reduces the cost of peanut harvesting. It has more advantages than domestic and foreign turning equipment.

[0037] In some other embodiments, the receiving drum 4 is located below the end of the conveyor chain 2 to receive the falling peanuts. The receiving drum 4 has discs 41 at both ends, and the discs 41 are connected to the swing frame 3 on the corresponding side. Multiple rollers 42 are arranged circumferentially on the receiving drum 4 and between corresponding discs. The outer periphery of the multiple rollers 42 is wrapped with elastic cloth 43. When the peanuts fall onto the elastic cloth between two adjacent rollers, they undergo elastic deformation. The soil on the peanuts is bounced off by the elastic cloth during the rotation of the receiving drum. When the peanuts fall onto the elastic cloth, they shake off the soil, and the elastic cloth undergoes elastic deformation, which temporarily slows down the falling of the peanuts. When there are enough peanuts and peanut vines to cause the receiving drum to rotate, the elastic cloth will shake off the soil on them, and no soil will remain.

[0038] In some other specific embodiments, side plate adjustment frames 12 are provided on both sides of the discharge end of the frame 1. The adjustment side plate 8 is rotatably connected to the side plate adjustment frame 12 by a pin. The adjustment side plate 8 is located above the receiving drum 4. The adjustment side plates 8 on both sides can be adjusted back and forth, up and down, and can also change the tilt angle. When the tilt angle is large, the fruit drop position on the receiving drum is narrower. When the tilt angle is small, the fruit drop position on the receiving drum is wider, which affects the spreading area. The spreading is thinner and can be dried better.

[0039] In other embodiments, the top of the gathering rod 9 is provided with a movable head, and the bottom of the adjusting side plate 8 near the frame is provided with a movable seat. The movable head is rotatably connected in the movable seat and realizes the back-and-forth swing of the gathering rod. The top of the gathering rod 9 is provided with a return spring. The gathering rod 9 automatically resets under the action of the return spring. On the one hand, the gathering rod can restrain the falling material and prevent it from running outward. On the other hand, it can swing back and forth to prevent the peanut vines from getting caught during the movement of the frame.

[0040] The peanut harvester auxiliary device of this invention can change the landing position of the peanuts, complete the turning of the peanuts, and achieve better drying. Based on the gravity difference between the peanut vines and the peanuts, the peanuts fall onto the receiving drum first through the side plate. At this time, the peanut vines are not affected. According to the law of equilibrium, the peanut vines continue to fall. This process causes the peanuts to be turned over. The baffles on both sides can directly adjust the landing position of the peanuts, change the spreading area, and achieve better drying.

[0041] The peanut harvester used in conjunction with this invention includes an auxiliary device, a frame 1, a conveyor chain 2, a transmission mechanism, and a suspension 101. The front end of the frame 1 is a traction end 103, which is equipped with a suspension 101 for connecting to a tractor. The rear end of the frame 1 is a discharge end 102. The auxiliary device is detachably connected to the discharge end of the frame 1. The conveyor chain 2 is inclinedly arranged on the frame 1, with its inclined bottom end close to the traction end and its inclined top end close to the discharge end. The transmission mechanism is arranged on the frame 1 and transmits power from the tractor to the conveyor chain 2. Using the peanut harvester of this invention, peanuts can be turned over so they are spread out to dry. The position of the fallen peanuts can be adjusted to achieve a larger spreading area. The turning part requires no power, saving fuel consumption and operating costs, and is convenient and fast.

[0042] Specific work process:

[0043] The shovel removes the peanuts by the roots and conveys them to the receiving drum via a conveyor chain. During this conveying process, the soil is shaken off. The peanut vines and pods at the discharge end are adjusted by adjusting the side plates to change the position of the pods on the receiving drum. After the pods fall, the vines continue to fall, and according to the law of equilibrium, they flip over, thus turning the pods. The receiving drum rotates under the eccentric gravity of the vines and pods, causing the peanuts to detach from the drum. If too much material falls, the receiving drum will swing backward under gravity to increase the falling speed and prevent clogging. This turning process does not require external power. The gathering rod can gather the falling material and also swing backward adaptively to prevent the vines and pods from getting caught. Adjusting the side plates can change the position of the pods on the receiving drum. Compared with foreign line-turning methods, this invention can increase the spreading area, improve drying efficiency, and is convenient, efficient, and inexpensive to use, making it easy to promote and use.

[0044] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
