The inclination guide part 21 a is configured to incline downward at a steep angle larger than the inclination angle of the bottom plate 21. In addition, the inclination guide part 21a is corresponded to "the conveyance downstream side edge part of a baseplate" in this invention. The end guide portion 21b is configured to bend a predetermined angle further downward from the inclined guide portion 21a. In the present embodiment, the terminal guide portion 21b extends in a substantially vertical direction from the inclined guide portion 21a.

  A notch 24 that faces the operation lever 17 is formed at the center of the end guide portion 21b so that the operator can easily operate the lever.

  The first side wall 22 is erected at one end of the bottom plate 21 in the short direction, and is formed entirely as a flat plate. Moreover, the 1st side wall 22 inclines by the predetermined angle toward the trough 15 which adjoins from the edge part of the transversal direction of the baseplate 21 (refer FIG. 4). Further, the first side wall 22 has a first projecting portion 22 a that projects from the transport downstream end of the bottom plate 21 in the transport direction. The height of the lower end of the first protrusion 22a is aligned with the height of the lower end of the terminal guide portion 21b.

  The second side wall 23 is erected on the other end portion of the bottom plate 21 in the short direction. The second side wall 23 is formed in a chevron cross-sectional shape obtained by bending a flat plate into a mountain fold, and covers the first side wall of the adjacent trough 15 over the entire length.

Further, a vertical wall portion 7 a having an upper end portion located above the trough 15 is erected at an outer edge of the upper end opening portion of the supply hopper 7. The vertical wall portion 7a corresponds to the “third regulating member” in the present invention.

(Effect of embodiment)
According to the present embodiment, for example, when the article is a long and easy-to-entangle article such as sprout or radish, one of the articles transferred from the top cone 12 of the dispersion feeder 5 to the trough 15 of the linear feeder 6. Although the portion may straddle the second side wall 23, the first upper surface portion 23p, which is the transport upstream side portion of the second side wall 23, has a relatively small lateral width, and the height from the bottom plate 21 is the transport downstream side (first 2 is lower than the upper surface portion 23q), so that one end or both ends of the elongated article straddling the first upper surface portion 23p of the second side wall 23 is one bottom plate 21 or the second side wall. The two base plates 21 are in contact with the two bottom plates 21 and are reliably subjected to vibration from the trough 15 and sent outward. During this vibration conveyance, a part of the article is also distributed in the lateral direction. .

  The second side wall 23 includes a first upper surface portion 23p inclined downward along the transport direction and a second upper surface portion 23q provided substantially horizontally with respect to the horizontal plane, and the side wall is in the middle of the transport direction. It is possible to suppress the stagnation of the article without receiving a large conveyance resistance at the starting end portion of the rising inclined portion as in the conventional example of rising upward from above (Patent Document 1).

  The article placed on the bottom plate 21 and oscillated and conveyed outward is put into the supply hopper 7 from the end portion of the bottom plate 21. The end portion of the bottom plate 21 has an inclined guide portion 21a. Since the substantially vertical end guide portion 21b is refracted, even an elongated and easily entangled article is caught by the bottom plate end portion and stagnated, or it goes around the end and falls directly on the collecting chute 9, or the supply hopper 7 It does not get caught on the inner opening edge.

  Articles that have reached the end of the bottom plate 21 come from three sides at the end guide 21b that enters the opening end of the supply hopper 7, the first protrusion 22a of the first side wall 22, and the second protrusion 23a of the second side wall 23. Since it is guided and discharged in the enclosed state, it is smoothly put into the supply hopper 7 without being caught by the opening end of the supply hopper 7.

  Further, the article conveyed on the bottom plate 21 is received by the vertical wall portion 7a erected on the outer edge of the supply hopper 7, and falls into the supply hopper 7 without spilling outward. go.

  When the article vibrated and transported while straddling the second side wall 23 reaches the second upper surface part 23q that spreads out, the lateral width gradually increases, so that the contact part between the straddled article and the second upper surface part 23q increases. Thus, vibration is effectively transmitted to the article, and even if the article straddling the second upper surface portion 23q is entangled into a lump, the lump can be solved by vibration, and the second side wall 23 The two troughs 15 adjacent to each other with the second side wall interposed therebetween can be distributed along the shape. Further, since the second upper surface portion 23q is not inclined downward like the first upper surface portion 23p, the second upper surface portion 23q ensures a period during which the article is conveyed, and the article vibrates sufficiently during that time. Can be added to solve the tangled article.

  Further, the article conveyed to the end of the second side wall 23 without being distributed to the left and right is received by the vertical ribs 27 and is prevented from further outward movement. It is distributed to two troughs 15 that are adjacent to each other.

(Other embodiments)
The present invention can also be implemented in the following forms.

  (1) As shown in FIGS. 12 and 13, the extended ends of the first side wall 22 and the second side wall 23 of the trough 15 are connected by a vertical wall portion 28 as a second restricting member, and the end of the bottom plate 21. This is implemented by forming a rectangular discharge port surrounded by the first protruding portion 22a of the first side wall 22, the second protruding portion 23a of the second side wall 23, and the vertical wall portion 28 outside the portion. You can also. According to this structure, it can respond also to the supply hopper of various specifications which are not provided with the vertical wall part 7a.

  (2) In the above-described embodiment, the inclined guide portion 21a and the end guide portion 21b are formed in a two-fold manner at the end portion of the bottom plate 21, but the inclined guide portion 21a is omitted and only the end guide portion 21b is omitted. It may be refracted vertically downward.
