Description

Peanut Harvester with Select System

The present invention relates to a peanut harvester having a selection system, and more particularly, to an improved peanut harvester which can automatically process the whole process of peanut harvesting by picking and collecting the ground peanut pod with the stem in the ground.

Peanut harvest consists of digging up stems with peanut pods hanging from the ground and removing peanut pods from the stems, but peanut pods are used to excavate stems in the ground and shake off the soil Next, it requires a lot of manpower because it must be separated and selected. Especially, if the harvest time is short and peanuts are not harvested in a timely manner, the harvest loss is very large and the merchandise is low. In particular, the labor required for harvesting peanuts is 34% of the total labor for peanut cultivation. However, in addition to the absolute shortage of rural labor force due to urbanization, the labor shortage is severe because peanut production sites become complex and require a lot of manpower at the same time. Therefore, in order to solve this problem, the mechanization of the whole work of peanut harvesting has been urgently required.

Research and efforts on the mechanization of peanut harvesting have led to the development of excavators to dig up grounded peanuts with their stems and power de-collectors to select them. However, the peanut excavator has a big difference in the degree of work according to the soil characteristics, and there is a problem that the dirt removal work must be carried out by manpower, and the selection work by the power stripper also requires a lot of manpower. There was an urgent need for the development of a peanut harvester capable of automatically performing the entire work of harvesting peanuts.

The present invention requires a lot of manpower, but in order to solve the problem caused by labor shortage, in the cultivation of peanuts, harvesting, squeezing, screening, and collecting at the time of harvesting are carried out in a consistent manner. The purpose of the present invention is to provide a peanut harvester that automates the entire work of harvesting peanuts while improving the efficiency of harvesting soil and picking after removing stems.

A quick feed part having two barrels to disperse and separate the dust, the soil separated from the peanuts separated from the quick shake part When separating peanuts from the east, transfer means for separating and picking up fallen twigs, etc., remove the soil on the surface of the peanuts transferred by the transfer means and separated the twigs introduced with peanuts during the barrel It comprises a selection means for collecting.

Hereinafter, with reference to the accompanying drawings showing an embodiment of a peanut harvester according to the present invention will be described in detail the present invention.

Figure 1 schematically shows the configuration of the peanut harvester 1 according to the present invention, and removes the body part of the harvester and shows the characteristic components according to the present invention in order to understand the configuration. At the front of the harvester 1, two stem guide guides 2 are respectively provided at the bottom of the front plate 3, as shown in FIG. 2, so as to pull up the peanut stem while scattering two rows of peanuts planted with peanuts. A lug 4 is provided which is mounted and rotates around the outer circumferential surface of the faceplate. In addition, the rear of each stem guide guide (2) is disposed below for example about 15cm further down there than the excavation blade (5) for digging into the dig during the run of the harvester to lift the peanut root portion with the soil Each is attached. Accordingly, as the harvester 1 runs, both peanut stems of the toad are lifted by the stem guide guide 2 and the stems are also raised by the excavation blade when the lugs of the front plate are collected and rotated inward. Will be raised. At this time, as the pair of chains 6 disposed on the rear upper side of the excavation blade 5 are engaged and rotated, the stems of peanuts are engaged between the chains 6 to move backward together with the chains. This configuration itself is similar to those known in combine harvesters, such as harvesting crops, and thus are not characteristic features of the present invention, but are also used in the peanut harvester of the present invention and are described by reference.

Peanut harvester (1) according to the present invention is excavated from the pit as described above, the soil whisk means to shake off the soil from the root portion of the peanut to be transported to the rear by interlocking between the chains (6), and peanuts from the root portion And a selection means for separating soil and peanut stems and separating and selecting only peanuts.

As shown in FIG. 3, the dust-rolling means is rotatably supported by the support member 8 on both sides of which a roller 7 having protrusions formed on an outer surface at the rear side of the excavation blade 5. Rotating mud plate 10 that is rotated by receiving power from a chain drive means not shown in the conventional transmission means 9, such as a belt is mounted on the support member 11 supported at both ends and the rotary soil The hair plate 10 is formed with a plurality of holes in the height direction of the support member 11 to adjust the height. Therefore, the soil mass of the root portion of the peanuts to be transported between the chains 6 first hits the rollers 7 and is in a state where it can be partially crushed or easily crushed, and then the rotary soil continues to be transported and rotated. As a result of the impact on the hair plate 10, a large lump of dirt buried in the root portion of the peanut which is in good condition to be crushed by the roller 7 is shaken off.

The rear portion of the rotary mud plate 10 is provided with a pair of mud plate 12, 12 'as shown in Figure 4 to more completely remove the soil in the state sandwiched between peanut roots. The dirt boards 12 and 12 'are eccentrically fixed to their respective shaft portions 13 and 13' as shown in a plan view schematically in FIG. 4, and the shaft portions thereof are connected to each other by a connecting portion 14. And the rotational movement by the link 15, for example, when the link 15 is rotated clockwise in the drawing together with the shaft 13, the shaft portion 13 'connected by the connecting portion 14 is counterclockwise. Direction, the earthen boards 12 and 12 'have a curved shape and are mounted eccentrically to oscillate according to the rotational movement of each shaft, as shown by the arrows in the figure. Done. Accordingly, when the peanut root portion is transported through the soil feather plates 12 and 12 ', the soil feather plate 12' on one side swings as shown by an arrow to hit the root portion, and at this time, the soil feather plate (12) is located in a position away from the root portion, and then the earthen board (12) hits the root portion and the earthen board (12 ') is in a position away from the earthen board (12) 12 '), the soil between the peanuts at the root of the peanut is almost completely removed.

In this way, the soil is completely removed from the roots of the peanuts and transported to a pair of rotating barrels 16 disposed behind them (see FIG. 5) to disperse the peanuts from the roots and to separate the barrels. It falls on the screen 17. The barrel 16 is rotated adjacently, as shown schematically in FIG. 5, and the peanut root portion of the soil is shaken between them, and the peanuts are scattered from the roots by the teeth fixed on the outer surface of the barrel. Separated, the stems from which the peanuts are separated are continuously transported to the rear with the chain 6 engaged and then collected separately.

Peanuts separated from the barrels 16 are transported backward on the transfer screen 17, so that the twigs and the soil, which are shaken together when separated from the barrels, are separated. The transfer screen 17 for this is a screen member 21 of a plurality of mesh structures in the chain 20 is rotated by the two sprockets (18, 19) as shown in the side view of Figure 6 and the top view of Figure 7 They are mounted, and proceed from left to right in the drawing to transfer the peanuts and twigs separated by the barrel 16 to the selection means for separating. In order to adjust the tension of the chain, an elongated bolt 22 is mounted on the shaft of the sprocket 18 so as to adjust the position of the shaft with respect to the frame not shown in the drawing. The holes of the screen member are formed with holes of a size that the peanuts do not pass through so that when the peanut is separated in the barrel 16, the falling soil passes through the screen member so that only twigs and peanuts are transported.

Peanut conveyed by the transfer screen 17 is still soiled on the surface, the rear sprocket (19) to remove the twigs carried by the transfer means and to remove the soil on the surface of the peanut shell The selection means provided is a vibrating screen 23 for separating the twigs, as shown in the side view in Figure 8, a brushing device 24 for removing dirt on the peanut shell provided on the lower side of the front, to the brushing device From the inclination screen 25 for transporting the peanut in a state that is cleanly removed dirt and air blowing means 26 provided on the lower side of the inclination screen (25). The twigs and peanuts transferred from the transfer screen 17 are first dropped on the front part of the vibrating screen 23 of FIG. 10, and the front part has a plurality of rods 27 spaced apart so that the twigs are caught. Is guided by the inclined plate 28 to fall to the brushing device 24. At this time, when the twig and the vinyl are moved to the screen member 29 in the rear part by the vibration of the vibrating screen 23, the wind blown by the blowing means 26 blows to the rear part of the vibrating screen 23 to blow the twig and the vinyl. So only peanuts are separated from twigs and vinyl. The separated peanuts fall down and fall on the brush 30 of the brushing device 24 shown in FIG. 9, and the distance between the mesh 31 and the brush 30 is changed as the brush rotates counterclockwise. Penetration of the peanut shell is wiped clean by the brush as it passes through the dirt from the net through the holes 31 and only the peanuts fall on the inclined screen (25). The separated twigs and vinyl are continuously moved backwards by blowing and are discharged through a plurality of guide rods 32 inclined upwardly behind the screen member 29 so as to be put in a collection network not specifically shown in the drawings. It becomes.

As shown in FIGS. 8 and 10, the inclined screen 25 has a plurality of inclined plates 34 at both ends thereof fixed to a supporting member (shown in dashed lines in FIG. 10), and the inclined plates are inclined apart from each other. Is installed. The support member is made by connecting the vibration screen 23 and the levers (37, 37 ') disposed thereon, and the peanuts are discharged from the surface is wiped by the brush by rotating in the brushing device (24) It is collected between the inclined plates 34. The lever 37 is hinged to the vibrating screen 23, and the lever 37 'is particularly fixed for the support so that the inclined screen also vibrates as the vibrating screen 23 vibrates as described below, thereby brushing. The peanuts discharged from the device 24 between the swash plates 34 are moved backwards while jumping.

When the shaft 40 is rotated by a pulley not shown in the drawing as shown in FIG. 8, the vibrating screen 23 rotates the eccentric cam 41 coupled to the shaft while being engaged with the eccentric cam. As the 42 is engaged with the outer surface of the eccentric cam to form an elliptic trajectory, the upper shaft 43 is rotated at a preset angle, for example, at a 45 degree angle with the lower shaft 43 being hinged and fixed. The end of the upper shaft is rotatably mounted on the plate 38 provided on both side walls of the vibrating screen 23, and the front side of the vibrating screen 23 is supported by a support lever and a hinge 39 The vibration screen 23 vibrates back and forth and up and down by the rotational movement of the upper shaft 43 according to the rotation of the 40. As the vibrating screen 23 vibrates so that the inclined screens 25 connected to each other by the lever 37 hinged thereto vibrate up and down, the peanuts collected between the inclined plates 34 are popped up. 34 is moved between the inclined plates in the rear by the wind by the blowing means 26 inclined inclined along the inclined surface in the gap between the. As a result, the dust is finally removed and dropped to the conveying roller portion 36 schematically shown through the screen member 35 at the rear and transported to the collection tank.

According to the present invention, the stem of the peanut is excavated to remove the soil from the root portion by the soil dusting means and the vibrating soil peeling plate, the peanut is separated by the barrel, and then sent to the selection means through the transfer means, brush The machine cleans the soil from peanut shells, separates twigs and soil, and automatically performs a series of peanut harvesting operations that collect only the selected peanuts. This reduces labor and improves work efficiency. There is an effect to be improved.
