Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a sample grain extraction device for a rice hulling and sorting machine.

1. Modern rice centers are equipped with a receiving hopper, a rough sorter, an automatic moisture meter, and a weighing device in order to streamline the process of temporarily collecting unhulled rice.

For sorting, we have automated each work in the working equipment section, from the conveyor to the cargo receiving tank, and we have begun to centrally perform various data obtained during the sorting process, such as storing the variety and farmer's card data and printing them on processing slips, etc. ing. In this case, before the imported paddy rice is put into the receiving tank,
The inspection department extracts a sample of the unhulled rice, obtains the weight of the sized brown rice for the received unhulled rice that should be included in the calculation of moisture content and yield, calculates the appropriate payment price based on that, and calculates the weight of the sized brown rice. Some of them are sample grains! It is necessary to collect it at ~.

In the discharge process of the test hulling and sorting machine, which hulls the received paddy rice with a test huller, sorts the grains with a test sorter, and measures the weight of grained brown rice with a weighing machine, the unripe rice discharge path and brown rice In addition to arranging the discharge passages in a branched manner, a receiving gutter with a unique structure is provided in the flow path of the brown rice discharge passage to ensure that some of the sample grains from the sized brown rice are collected.
- We aim to develop and provide high-performance equipment that can collect samples smoothly and quickly.

The present invention will be explained with reference to embodiment figures. Figure 1 is a cross-sectional view of a rice huller (1) and a supply hopper (1) at the top of the machine (1).
2), two existing rolls (8) made of hard rubber (
A test rice hulling machine (5) with 4) mounted on the shaft was installed in series, and the rolls (8) and (4) were placed opposite to each other with a slight gap between them, and the speed of each roll was varied by θ. be. Therefore, the test paddy supplied to the upper supply hopper (2) flows down and is supplied to the huller (5) by the vibration action of the vibration device (6), and passes through the roll gap of the huller (5). During this time, it is deweighed by friction with the rolls. The existing grains discharged from the rice huller (5) fall together with the rice husks, and in the wind selection section (7) on the way, relatively light rice husks are removed from the machine by the blower (8). On the other hand, the existing grains are fed to a grain sorter (9) or (lO) consisting of a porous wall sorting tube at the bottom, and as the sorting tube rotates, immature rice and broken rice fall from the porous wall surface and are separated and separated into a weighing machine ( 11) is supplied to
The unripe rice etc. weighed by the container (11) is fried and supplied to the sample grain extraction device (13) by the discharge thrower (12). In addition, when the unripe rice is weighed, the sized brown rice remaining in the porous wall sorting cylinder is transferred to the weighing machine (11).
At the same time, the discharge valve (not shown) at the bottom of the river opens and the brown rice flows down to the discharge thrower (+2), The paddy is fried and supplied to the sample grain extraction device (13) by the raw paddy input hopper (14).The paddy is weighed by the raw paddy weigher (15) and sent to the throat
6), the grain is fried to the supply hopper (2) at the top of the huller, so the total weight of the paddy, the weight of sized brown rice, and the weight of immature rice are all measured in the grain flow process.

Next, the sample particle extraction device (13) is
The diagram will be explained. The box-shaped machine frame (17) has an upper grain feeding port (
18) and a lower grain discharging port (19) are respectively provided and connected by an upright immature rice discharge path (20).
A branch switching valve (2) is provided on the upper side of the branch boat (21
) section and the lower grain threshing port (19) are connected by a detour-shaped brown rice discharge path (23) with a bent channel section (22), and the front position where the rice grains in the bent channel section (22) flow down. (A) is provided with a sample particle receiving gutter (25) with a discharge valve (24), and a sample particle outlet (26) is provided below the receiving gutter (25). (27) is the operating lever of the tJl outlet valve (24).

Therefore, when unripe rice, etc. is discharged from the grain sorter (9) or (10), the branch switching valve (21) of the sample grain extraction device is activated by a signal from the control device (not shown).
is blocked and the unripe rice discharge path (2+1) side is opened, so the grain sorter is removed from the grain sorter to the weighing device (11).

Immature rice, etc. that flows into the upper grain feeding port (18) of the nuclear body fi'r through the discharge thrower (12) flows down the upright immature rice discharge channel (20) and enters the lower grain feeding port. (19) and is discharged from the machine. In addition, when sized unpolished rice is discharged from the grain sorter (9) or (10), the branching switching valve (21) is activated by a signal from the control device to overturn the brown rice discharge path (23). ) side is open, so the sized brown rice flowing into the upper grain feeding port (18) of the device flows through the detour-shaped brown rice discharge path (
23) flows through the bent flow part (22) into the sample particle receiving gutter (25) at the front position (A), and the sample particle receiving gutter (25)
5) Excess brown rice passes to the lower grain discharging port (+9) side and is discharged from the machine through the discharge port. Then, the sized brown rice remaining in the sample grain receiving trough (25) is taken out from the sample grain outlet (26) at the bottom by opening the operating rod (27) provided in the discharge valve (24). They are often collected in a storage container (not shown) and stored in the testing department.

Further, in claim (2), an inspection window (28) is provided on the side machine frame (17) surface of the sample grain receiving trough (25).
), the sample particles inside the receiving gutter (25) can be checked through the inspection window (28) during work, which has the effect of ensuring the sample particle removal work and promoting work efficiency. be.

As described above, the sample grain extracting device of the hulling and sorting machine of the present invention can reliably, smoothly and quickly collect some sample grains from the grained brown rice whose weight has been measured in the hulling and sorting process of the unhulled rice received at the rice center. In addition, it is possible to promote the automation of the inspection work for each individual producer, and it has the effect of streamlining the voluntary inspection of paddy rice received by rice centers and the like.
