[0002]

2. Description of the Related Art The above quality measuring apparatus is disclosed in, for example,
As shown in JP-A-300350, the above-mentioned grain processing equipment is provided and used. In other words, the grain processing equipment, the grain before receiving to the receiving unit, or
The grain to be inspected, which is collected from the grain before the weighing is performed after the grain is received by the receiving unit, is supplied to the quality measuring device in a state where the drying process is not performed. It is to detect the information, thereby supplying the inspection target grain collected when the weighing is carried out after receiving in the receiving unit to the quality measuring device,
Compared to detecting the discrimination information for the sorting, to avoid the occurrence of a waiting time until the weighed cereal is shifted to processing in the drying unit, further, drying the collected inspection target cereal Since the drying process takes a longer time than what is supplied to the quality measurement device after
In order to avoid the occurrence of more waiting time, the efficiency of grain processing has been improved as much as possible.

[0003] In addition, conventionally, a grain to be inspected supplied to a hopper for supplying grains is supplied to a grain removal section as it is to constitute a quality measuring apparatus, and the grain is subjected to a grain removal treatment. Quantitatively weighed, in the quality measuring unit, for the quantified weighed grain, the moisture content by a taste meter,
The taste and the like are measured, and the appearance quality such as normal or defective grains is determined by an appearance grade meter, and the quality of the grain is measured.

[0004]

By the way, the cereal brought into the cereal processing equipment is one in which a culm in a field is cut by a combine or the like and the cut culm is transported by a truck or the like. In some cases, straw chips or grains with branch spikes may be contained, and when the inspection target grains collected from such grains are supplied to a quality measuring device, clogging of the straw chips and the like occurs in the evacuation unit, As a result, the operation of the escape unit may be stopped, or the escape operation at the escape unit may not be performed properly, and the escape rate may be reduced. May not be possible. In such a case, it is necessary to stop the operation of the quality measuring device and remove the clogging, and until the clogging condition is resolved, measure the quality of the grain received by the grain processing equipment and sort the grain. Therefore, there is a problem that the processing in the grain processing equipment cannot be smoothly executed based on the sorting determination information. In particular, the harvesting and harvesting work is concentrated at one time, and the delivery to the grain processing equipment will also be concentrated.If a trouble occurs in the quality measuring device during such a period, many grains brought in will be difficult to process. Can not be delivered to the customer, causing a lot of trouble for the supplier.

The present invention has been made in view of the above-mentioned circumstances, and a first object of the present invention is to perform a quality measurement operation smoothly on a grain to be inspected containing straw waste or the like without any trouble. A second object of the present invention is to provide a quality measuring device capable of measuring the quality of grains sequentially received by a grain processing facility with a quality measuring device and obtaining discrimination information for sorting. In order to detect the above-mentioned discrimination information as much as possible with respect to a grain to be inspected such as containing straw waste, the processing in the grain processing equipment can be smoothly executed based on the discrimination information for sorting. It is in.

[0006]

According to a first aspect of the present invention, there is provided a grain quality measuring device, comprising: a hopper to which a grain to be inspected is supplied; a rough-selection unit for sorting the grain supplied from the hopper; A crushing unit for crushing cereals supplied from the roughing unit; and a weighing unit for cereals supplied from the crushing unit to separate a set amount of cereals necessary for quality measurement from other cereals. And a quality measuring unit that measures the quality of the grain of the set amount separated by the quantitative measuring unit. In other words, the grain to be inspected supplied from the outside to the hopper is supplied from the hopper to the rough-selection section, and the swarf and the like are removed by the sorting operation of the rough-selection section. Is supplied to the grain, and is subjected to de-aeration processing. The quantitative metering section weighs the grain after the de-aeration processing to separate a set amount of grain necessary for quality measurement from other grains, and the separated set amount Is measured by a quality measuring unit.

[0007] Therefore, even when the grain to be inspected supplied to the quality measuring apparatus contains straw waste, the grain from which the straw waste and the like have been appropriately removed by the sorting operation of the rough selection section is removed in the removal section.ぷ Because it will be processed, as before,
In the case where the grain to be inspected containing straw waste or the like is supplied to the escape unit as it is to perform the escape processing, the straw waste or the like is clogged in the escape unit, and as a result, the operation of the escape unit is stopped. Or the escape operation in the escape unit may not be performed properly and the escape rate may decrease, which may make it impossible to perform the quality measurement properly in the quality measurement unit. Thus, a quality measuring apparatus capable of avoiding such inconveniences and performing the measuring operation with as little trouble as possible has been obtained.

According to a second aspect, in the first aspect, the rough-selecting section moves the cylindrical body having an outer peripheral wall formed with a large number of passage holes through which the grains are passed by moving the cylindrical shaft center in the horizontal direction. It is configured so that it can be driven and rotated around the axis of the cylinder in a state where it is turned, and the grain to be inspected passes from the upper side to the lower side of the cylindrical body to perform a sorting operation. In other words, a cylindrical body having an outer peripheral wall formed with a large number of passage holes through which grains pass is driven and rotated around a horizontally oriented cylindrical axis,
When the grain to be inspected is supplied to the upper side of the cylinder, the grain passes through a large number of through holes formed in the outer peripheral wall of the cylinder and passes from the upper side to the lower side of the cylinder. It is skipped in the direction of rotation of the cylinder and is thereby sorted. Therefore, when the coarse selection unit is configured by a rocking type rough selection machine that performs a selection operation by rocking a selection plate on which a selection target is placed, for example, the rotation operation is slow, so that the selection operation is performed. The sharpness is bad,
In addition, the vibration caused by the swinging operation is large, and the rotation operation can improve the sharpness of the sorting compared to a large device for the swinging mechanism and the sorting plate. Therefore, there is an advantage that the size can be reduced and a small coarse selection unit can be obtained, so that the preferable means of claim 1 can be obtained.

According to a third aspect, in the first or second aspect, a feeder is provided for transporting the grain to be inspected from the hopper to the rough selection unit by a set amount per unit time. Therefore, by the feeder, the grain to be inspected is transported from the hopper to the rough-selection unit by the set amount per unit time, and when there is no feeder, when a large amount of grain is supplied from the hopper to the rough-selection unit at one time, Cereals may be removed together with the straw debris and the like that are sorted and removed in the roughing section, causing a loss of the grains. Such a disadvantage can be avoided as compared with the possibility that the performance (declination rate) may be reduced, and the preferable means of claim 1 or 2 can be obtained.

According to a fourth aspect, in the third aspect, the feeder is constituted by a rotary feeder.
Therefore, for example, in a vibration-type feeder that vibrates and conveys a diaphragm on which grains are placed, vibration noise accompanying the swinging operation is loud, and unconveyed grains may remain in corners and the like with respect to the center of the diaphragm. In comparison with the case where the conveying member such as a roll is rotated, the operation sound can be reduced, and the unconveyed grain can be conveyed without remaining, so that the preferable means of claim 3 is obtained. .

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the protrusion is configured to be a shock-absorbing type. Therefore, since the grain is subjected to dehulling treatment by applying an impact, when the dehulling unit is configured as, for example, a roll-type milling machine, it is possible to satisfactorily dehull the grain in a raw rice state that has not been dried. Compared to the case where the processing cannot be performed, the grain in the raw unhulled state can be satisfactorily dewatered.
The preferred means of any one of claims 1 to 4 is obtained.

According to a sixth aspect, in any one of the first to fifth aspects, a supply port for directly supplying a grain to be inspected to the rough-selection unit or the scraping unit is provided.
Therefore, if the grain to be inspected supplied to the hopper is insufficient for the set amount required for quality measurement, additional grain is directly supplied from the above supply port to the roughing section or the removal section to control the quality. The set quantity required for measurement can be set, and quality measurement can be performed smoothly.Especially, when grains to be inspected are sequentially supplied to the hopper, the next time the grains in the hopper are sent to the roughing section, Cereal is supplied to the hopper, and additional cereal cannot be supplied from the hopper.If the supply port for the additional input is not provided, quality measurement cannot be performed. Therefore, the preferred means according to any one of claims 1 to 5 can be obtained.

According to a seventh aspect, in any one of the first to sixth aspects, a supply detecting means for detecting whether or not the grain to be inspected has been supplied to the hopper, and controlling a quality measurement operation of the grain. Control means is provided, and the control means detects that the grain has been supplied to the hopper by the supply detection means, and starts the quality measurement operation of the grain from the hopper. It is configured to control each of a supply operation to the rough selection unit, an operation operation of the rough selection unit, an operation operation of the escape unit, an operation operation of the quantitative measurement unit, and an operation operation of the quality measurement unit. I have. Therefore, as the grain to be inspected is supplied to the hopper, the supplied grain is supplied from the hopper to the rough-selection section, sorted in the rough-selection section, de-slipped in the stripping section, and quantified. Since the set amount of grain is separated in the measuring section and the operation is controlled so that the quality of the grain is measured in the quality measuring section, for example, after supplying the grain to be inspected to the hopper, a manual switch or the like is used. In the case of inputting the start signal of the quality measurement operation, it is troublesome to operate the switch each time, and the operation based on the information that accurately detects the supply of grain is compared with the case where the switch may be erroneously operated. Claim 1 can appropriately start the quality measurement operation while reducing the operation burden on the personnel.
The preferred means according to any one of (1) to (6) is obtained.

According to an eighth aspect of the present invention, in the seventh aspect, the quantitative measuring section is provided with a quantitative detecting means for detecting whether or not the set amount of grain is separated, and the control means includes:
After detecting that the cereal is supplied to the hopper by the supply detecting means, if the set amount of cereal is not detected by the quantitative detection means even after a lapse of a set time, In addition, it is configured to operate a notifying means for notifying that the supply amount of the grain to be inspected is insufficient. In other words, during the set time, after the grain to be inspected is supplied to the hopper, the grain is processed in the roughing section and the stripping section and sent to the quantitative metering section, where the set amount of grain is separated by the quantitative metering section. It is set to the time obtained by adding the allowance time to the time required until. Therefore, it is automatically determined that the supply amount of the inspection target grain supplied to the hopper is insufficient with respect to the set amount necessary for quality measurement, and the shortage of the grain supply amount is notified, and based on the notification, for example, Since additional grains can be supplied from the supply port to the roughing section and the milling section, the measurement operation is started in a state where the grain supply amount is insufficient, and the quality measurement operation is not performed properly. Such a situation can be appropriately avoided, and the preferable means of claim 7 can be obtained.

According to the ninth aspect, the receiving unit that receives the grain in the receiving unit and performs a receiving process of measuring the received grain, and sorts the grain subjected to the receiving process based on the discrimination information for sorting. It is a grain processing facility provided with a drying unit that performs a drying process in a state where the grain is dried, and a storage unit that stores the dried grain, wherein the grain quality measuring device according to any one of claims 1 to 8. Provided, grain before inspection to the receiving unit, or the grain to be inspected collected from the grain before receiving the receiving unit and before the weighing is performed, the quality measurement without drying processing The quality measuring device is configured to supply the information to the apparatus and detect the classification determination information. Therefore, the grain before inspection into the receiving part, or the grain to be inspected collected from the grain before being weighed after being received by the receiving part, is dried while the receiving part performs the receiving processing. Since the quality is measured without processing and the discrimination information for sorting is detected, it is possible to minimize the waiting time for the detection of the discrimination information. It contains a lot of grains with branch spikes,
Alternatively, even when a large amount of dust adheres after mowing, the quality measurement device removes the straw debris and the like appropriately and performs measurement in a state where jamming and other troubles are minimized to obtain the discrimination information for sorting. Therefore, the processing in the grain processing facility can be smoothly executed based on the sorting determination information. In particular, even when the delivery to the grain processing equipment is concentrated during the harvest season, the sorting information for many grains brought in can be measured and sequentially input to the processing equipment. As a result, it is possible to obtain a grain processing facility that can avoid inconveniences such as processing being interrupted and causing great trouble to the supplier.
