Description

TECHNICAL FIELD The present invention relates to a processing tomato harvesting auxiliary machine for manually picking and harvesting processing tomatoes, and more particularly to a processing tomato harvesting auxiliary machine equipped with a container mounting table. This makes it easy for farmers to harvest tomatoes, greatly improves work efficiency, and significantly reduces the production cost.
Further, according to the auxiliary machine for harvesting tomatoes for processing according to the present invention, manual harvesting of tomatoes can be facilitated even by elderly people, so that its practicality is high and the spread to general farmers is expected.

Unlike normal raw tomatoes, processing tomatoes do not mature in the order in which they are born, but they mature almost simultaneously, so they are harvested at the same time.
The cultivation of processing tomatoes is larger than the raw ones and the cultivation method is loose. And this tomato for processing is cultivated so that the fruit of the tomato can easily fall from the branch in order to facilitate the simultaneous harvest.

  The harvesting method is to manually pick up the fruits from the tomato branches (also called “branches”) that grow on the ground, and put them in a cell phone. There is a method of harvesting it by shaking it on the hopper of an auxiliary machine for tomato harvesting work, dropping the fruits, selecting the fallen items and storing them in a container, and further harvesting with a tomato harvester (harvester) is there. This method using a tomato harvester is a method in which the tomato is mechanically cut and shaken mechanically to remove the fruit, sorts the quality, and visually sorts the sorted to store the good product in a container.

In the case of a method of manually picking and harvesting from the branches that are growing on the ground, the container containing a predetermined amount (for example, 20 kg) is left behind in the field, and the tomato is moved all over the field. Since the branches of the tree are growing, it is not possible to remove the container while dragging the container. Therefore, the work of putting the pickled tomato fruit (sometimes simply referred to as “fruit”) into the carrying basket once, carrying it to the container and transferring it to the container is repeated. In this case, it is difficult to carry out this work because it crouches at the middle waist and picks up the fruit, and it is particularly burdensome for the elderly.
In addition, it is necessary to collect containers scattered in places where cutting has been completed and weigh them to adjust them to a predetermined weight.

[Conventional technology]
On the other hand, there is an auxiliary machine for harvesting tomatoes for processing so that the tomato harvesting work by picking can be efficiently performed in an easy posture, which is described in Patent Document 1. The invention of this application relates to an auxiliary machine for harvesting tomatoes for processing similar to that described in Patent Document 1.

The outline of an auxiliary machine for harvesting tomatoes for processing described in Patent Document 1 (hereinafter sometimes simply referred to as “auxiliary machine”) is as follows (FIGS. 10 and 11). That is, traveling control is performed by the operation lever 83, which includes the lifting conveyor 71, the hopper 72, and the loading platform 78, and travels by the crawler C.
The lifting conveyor 71 is disposed laterally in front of the auxiliary machine, and a large hopper 72 is provided at the lower end of the lifting conveyor 71.

One worker cuts the tomatoes for processing in front of the auxiliary machine, shakes it strongly on the hopper 72 and drops the fruit, and other workers at the rear of the auxiliary machine sort out and remove non-defective products. Housed in a container 77. In addition, the branch from which the fruit was shaken off is abandoned to the field as it is.
On the other hand, the fruit that has fallen on the hopper 72 is pulled up onto the loading platform 78 by the lifting conveyor 71, and the fruit that has been pulled up is temporarily stored in the shooter 74, and the foliage and defective products are removed by the operator. The selected non-defective product is transferred from the shooter 74 to the container 77 on the loading platform 78.

  In the tomato harvesting work using the auxiliary machine of this Patent Document 1, the above-described mowing work, the work of shaking the branches and dropping the fruits are performed by one worker, respectively, removal of foreign matters such as foliage, removal of defective products, Sorting by appearance such as color and shape is performed by another worker (a worker standing on the step).

[Problems of the prior art]
By the way, the harvesting work in the case of the auxiliary machine for harvesting work of Patent Document 1 is quick, and the sorting work by 3 to 4 persons can be harvested. Therefore, in order to increase the efficiency of the harvesting work by this auxiliary machine, it is necessary to correspond 3 to 4 sorting workers to one mowing worker. Also, the work of picking fruits from the cut branches and the work of selecting by visual inspection do not require physical strength. Therefore, even if the elderly are able to continue this for a long time, this can be continued for a long time.
From the above, the following points (a) to (e) should be taken into consideration in order to enable an elderly person to perform harvesting work efficiently.

(A) Since the loading platform area of the auxiliary machine is small, 3 to 4 people can efficiently pick up and sort together, and the sorting work can be easily accommodated in one container. Devise the arrangement of the person and the container,
(B) The picking operator and the container are always close to each other and there is as little movement as possible to accommodate the picked-up actual container;
(C) Sorting and weighing are completed when a predetermined amount is stored in the container so that the items stored in the container can be shipped as they are.
(D) It is easy to replace containers containing a predetermined amount of fruit.
(E) A container containing a predetermined amount of tomatoes can be easily unloaded from either the left or right side of the auxiliary machine.

The problems to be solved by the present invention are as follows.
About auxiliary machines for harvesting tomatoes for processing
The tomato stem for processing, which has been cut by hand, is transported to the work table on the carriage bed, picked up and sorted on the work table in a posture sitting on a chair, and this is easily placed in a container under the work table. The structure should be devised so that it can be accommodated and is weighed when a predetermined amount is accommodated in the container, and the container can be easily unloaded from either the left or right side of the auxiliary machine.

Cutting the tomatoes for processing tomatoes for harvesting in front of the auxiliary machine, and assuming that other workers pick up the fruit on the work table of the auxiliary machine and store it in the container, the following (a) to (g) Is due to.
(B) There is a slanting conveyor in front of the truck bed,
(B) There is a work table behind the inclined conveyor, and its tip is under the inclined conveyor.
(C) There are several chairs on the left and right outside of the work table,
(D) There are shooters on the left and right sides of the work table.
(E) There is a container table with a measuring instrument under the work table.
(F) The container mounting table has a lifter,
(G) The lifter pushes up the container on the container mounting table and selectively tilts it in both the left and right directions.

While slowly advancing the auxiliary machine for harvesting tomatoes for processing, the front of the tomato is cut, and the branches of the cut tomato are placed on the inclined conveyor.
The branch of tomato is conveyed backward by the inclined conveyor and dropped onto the work table from the rear end. If the tomato fruit falls on the inclined conveyor, it will not fall to the ground.
Sitting on the chairs on the left and right sides of the work table (both left and right when facing the front of the loading platform), multiple workers pick up the fruit on the work table and put the picked fruit into the shooters on the left and right sides of the work table. The fruit put in the shooter is stored in the container under the work table as it is.

The tomatoes for processing are picked visually when picked or put into the shooter.
This picking and sorting work is very easy because it is done on the work table and in a seated state, and its work efficiency is high, and picking and sorting from the branches growing over the field It is about 1.5 times as much as that.
Since the work of picking and sorting is performed on the work table, the efficiency is high and the sorting accuracy is high and stable. The harvesting by one person and the harvesting by 3-4 persons are almost balanced, and the harvesting and the harvesting work are performed very efficiently without interruption.
And picking and sorting work while sitting on a chair, so even elderly people can do it for a long time without difficulty.

  There is a container mounting table under the work table, and the container is placed on the container mounting table and weighed with a measuring instrument. Therefore, when the container reaches a predetermined weight, this is displayed on the measuring instrument. When the specified amount is reached, the container is lifted with the lifter of the container mounting table and tilted in either the left or right direction and pulled out from the bottom of the work table in the lateral direction (the lateral direction relative to the longitudinal direction of the loading platform) Replace with another container. And this replacement can be done easily even for elderly people because it is not necessary to lift and move the container by simply pulling it out from the bottom of the work table in a state where the container is pushed up and tilted. And the container pulled out from the bottom of the work table to the left side or the right side is pushed and cleared as it is forward or rearward on the right side or left side of the loading platform. And when the right side of the auxiliary machine is the cut area, you can easily unload what is mounted on the right side of the loading platform, and when the left side is the cut area, Can be easily unloaded.

  Since the harvesting in the tomato harvesting operation by the auxiliary machine of the present invention is merely a harvesting, the harvesting may be performed with a sickle having a long handle. Therefore, there is no need to mow at the middle waist, and it is not necessary to vibrate the mowed branches, so they can be hooked with a sickle and placed directly on the inclined conveyor, which is an extremely easy task. Therefore, the mowing work can be done for a long time without difficulty even by elderly people.

Embodiment
The lifter may be a power type or a manual type. In the case of a power type, a hydraulic cylinder may be used. In the case of a human power type, a pedal type operation means may be used.

An embodiment will be described in which one worker cuts and picks up and picks up two workers each sitting on the left and right of the work table 12.
There is an inclined conveyor 2 at the tip of a loading platform A of a carriage equipped with crawlers C, C, and a work table 12 is located at the approximate center of the loading platform A. And the front-rear length L of the loading platform A is 205 cm, and the left-right width W is 170 cm. The work table 12 has a ground height H of 130 cm, a height above the loading platform A of 70 cm, a front-rear length L1 of 160 cm, and a left-right width W1 of 80 cm.
There is an engine 28 at the rear of the loading platform A, and the engine 28 drives the drive wheel v of the crawler C and drives the hydraulic pump 29. In this embodiment, the drive wheel v is driven via a hydraulic motor (not shown). However, it can also be driven by a transmission mechanism equipped with a reduction gear.
An operation valve 30 and an operation lever 31 for traveling control are provided at the front and rear of the loading platform A, respectively, and both the front mowing worker and the rear picking operator control the start / stop of the auxiliary machine and the traveling speed. it can.

The inclined conveyor 2 is composed of a support frame 21 and a belt conveyor 22, and is disposed so as to protrude forward from the center of the front end of the loading platform A, and has a tray 23 at the lower end thereof.
As shown in FIG. 3B, the belt conveyor 22 includes a U-shaped conveyor frame 22a and a conveyor belt 22b. The conveyor belt 22b is driven by a driving roller 22c at the upper end, and the driving roller 22c is a hydraulic motor. It is driven by 22d.
The belt conveyor 22 has a width w2 of the conveyor belt 22b of about 45 cm, and its upper end extends to the top of the work table 12.
The conveyor belt 22b is provided with non-slip lateral blades (height of several centimeters) at intervals of 30 to 40 cm on the conveying surface, and the inserted branch P is pulled up by the blades. .
In addition, as long as the structure of the conveyor can be lifted up to the work table 12, any type of conveyor such as a bar conveyor (a belt formed by connecting left and right chains with a number of bars) can be used. Although it is good, a non-slip (corresponding to the above blade) is required on the conveying surface.
The inclined conveyor 2 is supported by an expansion / contraction stay 2c, and the ground height at the tip of the inclination conveyor 2 is adjusted by adjusting the length of the expansion / contraction stay 2c in multiple stages.
In addition, the expansion / contraction stay can be changed to a hydraulic cylinder, and in that case, the ground height at the tip of the inclined conveyor 2 can be easily adjusted.

The work table 1 includes front and rear table legs 11 and 11 and a work table 12, and the table legs 11 are fixed to the loading platform A with bolts. There are shooters 13, 13 on the left and right sides of the work table 12, and the upper end of the shooter 13 is an opening 13 a elongated in the front-rear direction of the work table 12.
There are a total of four chairs 4 on the left and right outer sides of the work table 12. In this embodiment, the opening 13 a of the shooter 13 is elongated and extends to the front of these chairs 4, but four openings may be provided corresponding to each chair 4.

  At the center of the loading platform A, there is a container placing table B with a measuring device 3 and a lift 5, and above that there is a work table 12. In this embodiment, the weighing instrument 3 and the lift 5 are separate and are separately assembled on the work table. The measuring instrument 3 can be assembled to the lift 5 to form a unit, and the unit (that is, the container mounting table B) can be attached to the loading platform A.

  When the weight of the container k reaches a predetermined amount (for example, 20 kg), the lift table 51 is operated by the pedal 59p to push up the container k and pull out the container k in the lateral direction. Further, the container is exchanged by raising the lift table 51 and inserting an empty container k under the work table 12 and then lowering the lift table 51 and placing the container k on the measuring instrument 3.

[Chair structure]
As shown in FIG. 9, the chair 4 includes a support arm 40 and a support shaft 41, and the support shaft 41 is fixed to the upper end of the chair leg 42. The center of the chair 4 is eccentric to the work table with respect to the support shaft 41 (eccentric distance e).
An inverted L-shaped bracket 43 is fixed to the lower end of the chair leg 42, and a pin 44 protrudes downward from the bracket 43.
A locking bar 45 is slidably inserted into a hole 43a in the lower part of the bracket 43.

The pin 44 is inserted into the vertical hole h of the loading frame f and the bracket 43 is placed on the loading frame f, and then the locking bar 45 is pushed in so as to contact the lower surface of the loading frame f. Thus, the chair legs 42 are attached to the cargo bed frame f.
Since the weight G of the operator m sitting on the chair 4 is eccentric with respect to the chair leg 42, a moment M due to the weight G acts on the chair leg 42.
The pin 44 fits in the vertical hole h, and the moment M acts to hold the load frame frame f from above and below by the bracket 43 and the locking bar 45. Therefore, while the worker m is sitting toward the work table 12, the chair leg 42 is firmly fixed to the cargo bed frame f.

On the other hand, when the worker stands up and leaves the chair, the moment M becomes small. Therefore, if the handle 45a is gripped and pulled, the locking rod 45 is easily pulled out. When the locking bar 45 is pulled out, the lower surface of the cargo frame f is not caught. Therefore, when the chair leg 42 is pulled up, the pin 44 at the lower end is easily detached from the vertical hole h of the cargo frame f and the chair 4 is detached from the cargo bed A. It is.
As described above, the chair 4 is easily attached to and removed from the loading platform A.

[Tsum removal sorting]
The branch P that has been cut and put into the tray 23 of the inclined conveyor 2 is pulled up to the work table 12 and dropped onto the work table 12.
Three to four workers sitting on the chairs 4 on the left and right outer sides of the work table 12 pull the branches P on the work table 12 toward the hand to pick up the fruit, and a good one is opened on the left and right openings 13a of the work table 12. In When picking up, a good one is selected and further selected when it is put into the opening 13a, so that the selection accuracy is high and stable. And since it sorts by picking up and throwing into the said opening 13a, the special effort for sorting is unnecessary.

What has been thrown into the opening 13 a is accommodated in a container k under the work table 12 via the shooter 13.
The container k is weighed by the measuring device 3 of the container mounting table, and when it reaches a predetermined amount, it is displayed and is replaced at that time.

[Container mounting table]
Next, an example of the structure of the container mounting table B will be described in detail. This is due to the measuring device 3 and the lift 5. In this embodiment, the lifting device 5 is arranged so as to cover the outside of the measuring device 3.
The lift 5 has four support rolls 5r arranged in the left-right direction, and the support portions 3a, 3a of the measuring instrument 3 protrude from between the support rolls 5r, 5r.
The container k is measured by being supported by the support portions 3a and 3a of the measuring instrument 3, and when the pedal 59p is depressed, the lift 5 is pushed up obliquely, and the container k is supported by the support roll 5r and pushed up. At this time, the container k is supported by a number of support rolls 5r and tilts to the right or left, so that it can be easily pulled out in the lateral direction.

The specific mechanism of the lift 5 is as follows. The lift 5 includes a lift table 51 and a lift base 52. The lift table 51 is placed on the lift base 52, and the left and right hinge shafts 53 of the shift table 51 are supported by the hinge bearings 52a of the shift base 52. 5 is assembled.
The lift table 51 has a square frame body including front and rear lift table frames 51f and left and right hinge shafts 53, and four support rollers 5r are attached to the lift table frame 51f. The support roller 5r is a simple one in which an outer cylinder is rotatably fitted to the central axis. Further, both ends of the hinge shaft 53 are fixed to the left and right lift table frames 51f.

The lift base 52 includes left and right substrates 54 and front and rear support plates 57. The lift base 52 includes substrates 54 fixed to the left and right ends of the front and rear support plates 57. The substrate 54 uses the bolt holes 54a. It is fixed to the loading platform A.
V-shaped hinge bearings 52a are provided at the left and right ends of the front and rear support plates 57, and the left and right pedal shafts 59a are rotatably supported by the support plate 57. A pedal arm 59b is fixed to one end of the pedal shaft 59a, and a lift lever 59c protrudes from the center of the pedal shaft 59a and extends in the opposite direction of the pedal arm 56a to just below the hinge bearing 52a. .
The other end of the pedal arm 59b extends under the foot of the worker m, and the other end has a pedal 59p.

  The above-described lift operation mechanism using the pedal shaft 59a, pedal arm 59b, lift lever 59c, and pedal 59p is provided on the front side and the rear side of the lift base 52 (front side and rear side toward the front of the loading platform). The left and right workers can pull out the container k.

The weighing instrument of this embodiment can set the weight to be measured, and when the weight reaches a set value, a notification sound by a buzzer is emitted. Accordingly, when a predetermined amount is stored in the container k, a buzzer is emitted, and this buzzer is used as a trigger to suspend the picking work all at once. For example, the worker m on the right side (the side where the cutting is finished) Step on. Then, the left hinge shaft 52a is pushed up by the lift lever 59c through the pedal arm 59b and pedal shaft 59a, and tilted rightward with the right hinge shaft 52a as a fulcrum. As a result, the container k is pushed up obliquely on the support roll 5r.
In this example, when the right worker depresses the right pedal 59p, the container k tilts to the right, so that the worker who depresses the pedal can pull out the container k.
Further, for example, an empty container can be easily placed at a predetermined position of the lift table 51 by depressing the right pedal 59p, tilting the lift table 51 to the right side, placing an empty container k thereon, and then pushing it.

[Modification]
In the embodiment of the lift 5 described above, the operator who operates the lift 5 can pull out the container k, but the lift table can be tilted in the direction opposite to the operated worker so that the worker on the opposite side can pull it out. . In this case, for example, the right pedal arm 59b may be connected to the right pedal shaft 59a, and the right hinge shaft 53 may be pushed up by the lift lever 59c protruding from the pedal shaft 59a. However, in this case, it is necessary to devise the structure of the lift operation mechanism so that the lift operation mechanism does not have a small lever ratio and the lift operation does not become heavy.
The lift operation mechanism may be hydraulically operated. In this case, the vertical hydraulic cylinders may be connected to the left and right hinge shafts 53, respectively. However, the hydraulic cylinder may act only in the push-up direction.
When the telescopic stay 2c that supports the inclined conveyor 2 is replaced with a hydraulic cylinder, the hydraulic cylinder may act only in the push-up direction.
