Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement of a chute device for a grain splitting detection device.

Prior Art A grain shell splitting detection device according to the prior art has a mechanism as shown in FIGS. 1 and 2. That is,
1 is a shell splitting detection device, 2 is a hopper, 3 is an inclined storage section, 4 is a guide plate, 5 is a supply gutter, 6a, 6b
is an electromagnet, 7a and 7b are adsorption plates, 8 is a chute,
9 is a groove through which grains flow, 10 is a slit, 11 is a light source, 12 is a detection head, 13a, 13b are lenses, 14a, 14b are fiber scopes, 15
a, 15b are detectors, 16 is a counter, 17 is a discharge port, and 18 is a chute support member.

The grains introduced into the shell splitting detection device 1 from the hopper 2 first fall into the storage section 3. Since the storage section is vibrated by the electromagnet 6a via the suction plate 7a,
With the vibration, the grains are gradually lifted up and enter the supply gutter 5 one by one along the guide plate 4. Although the supply gutter 5 is provided almost horizontally,
Since the grains are vibrated by the electromagnet 6b via the adsorption plate 7b, the grains flow down onto the grooves 9 of the chute 8 at intervals. Grain flowing down is slit 10
When positioned above, strong light is applied by the light source 11 and lens 13a provided below the slit 10. If there is a split in the grain, it will appear as a black line, which will be detected by the lens 13b, fiberscopes 14a, 14b and detectors 15a, 15b provided above, and recorded by the counter 16.

In such a grain splitting device, for example, in the case of rice, grains are roughly divided into round grains and long grains, and even though round grains vary in size depending on the variety, they always have the same shape. Since a chute with grooves is used, highly accurate detection cannot be performed.

Problems to be Solved by the Invention In view of the above-mentioned points, the present invention provides a chute that can be easily replaced with a groove having an optimal shape according to the grain shape of the grain to be detected, and has high accuracy. , it is an object of the present invention to provide a chute device for a grain body splitting detection device that is capable of highly efficient detection.

Means for Solving the Problems The present invention provides a chute device for a body splitting detection device in which a chute having a light transmitting portion is provided at an angle on a chute support member, in which an engagement recess is provided on one end surface of the chute, The structure is characterized in that one end of the chute support member is provided with an engagement piece that engages with the engagement recess, and the other end is provided with a movable support plate that abuts the other end surface of the chute.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 3 is a perspective view of the chute and chute support member of the present invention, and FIG. 4 is a sectional view thereof. A plurality of chute 8 having grooves 9 of a shape corresponding to the type of particle shape of the object to be detected are manufactured, and each chute 8 is provided with a slit 10 as a light transmitting portion. Furthermore, an engagement recess 8a is provided on the upper end surface, which is one end surface. The upper part of the chute support member 18 is formed into a frame 18a, and protrusions 18b are provided on both sides of the frame 18a to prevent the chute 8 from coming off when the chute 8 is placed thereon. A metal fitting 19 that engages with the recess 8a is provided. Further, a support plate 20 is fixed to the lower member 18c of the chute support member 18 with screws 21, and the other end surface of the chute 8 is held in contact with the support plate 20.

When the particle shape of the object to be detected changes, the chute 8 is taken out by turning the screw 21 and moving the support plate 20. At this time, the chute 8 is slid slightly downward to remove the metal fitting 19 from the engagement recess 8a, and the chute 8 is removed from the frame 18a. Next, select a chute 8 having a groove 9 with the optimum shape for the particle shape of the object to be detected,
By engaging the engagement recess 8a and the metal fitting 19, the frame 1
8a and fasten the support plate 20 with screws 21 to fix the chute 8.

Effects of the Invention As described above, the present invention allows the chute to be attached and detached very easily in the chute device of the grain body splitting detection device, so that the chute has a groove of an optimal shape according to the shape of the grain of the object to be detected. It is extremely easy to select and install the sensor in a short time, and it is possible to perform highly accurate and efficient detection.

In particular, in the present invention, the engagement piece provided on the chute support member is engaged with the engagement recess provided on one end surface of the chute, and the support plate provided on the chute support member is brought into contact with the other end surface of the chute. , the chute is positioned at the contact surface with the support plate, and its light-transmitting part is placed in the correct position, allowing light to be applied accurately to the grain, and the chute can be easily moved by simply moving the support plate. It can be removed from the chute support member.
