Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a cutting section cover of a pretreatment device for producing mobile seedlings.

0002

[Conventional technology]

Utility Model Publication No. 1-32820 has been used as a pre-treatment device for dividing rush seedlings. Japanese Utility Model Application Publication No. 2-81125 is known.

0003

[Problem that the idea aims to solve]

Although the above device does not include a cutting device that cuts the stem tips of rush seedlings to a fixed size, In order to produce strips of separated seedlings, the tips of the stems of the seedlings must be cut to a certain size due to mechanical processing. Even if it is not made into strips, it is desirable to cut it to size during preprocessing. . When cutting seedlings in this way, there is no problem, especially if you cut the seedlings horizontally. However, if you cut the seedlings while standing up for pre-treatment, cutting waste from the tip of the stem may fall downward. This may interfere with pretreatment work or be undesirable for maintaining the functionality of the equipment. .

0004

[Means to solve the problem]

In order to solve the above problems, in this invention, the seedlings are moved in an upright position. Provides a mechanism that allows cuttings from the tip of the stem to fall off smoothly during pretreatment. The seedlings for pretreatment are placed in an upright position tilted laterally with respect to the direction of movement. It has a seedling transport route for importing and supplying, and the seedlings being transported are placed at an upper position on the lower side of the transport route. In a mechanism provided with a cutter 4 for trimming the stem tip side of the stem, the lateral side in the direction of seedling movement A cutting section cover 36 is provided to be inclined to the surface side of the cutter 4 and close to the surface side of the cutter 4. The section cover 36 is formed with a guide section 37 for carrying in seedlings that terminates near the seedling cutting end position. It is characterized by what has been achieved.

[0005]

[Effect] The seedlings fed and conveyed along the seedling conveyance path are guided by the guide section 37 of the cutting section cover 36. While being guided, it reaches the cutting part of the cutter 4 and cuts the stem tip to a fixed length, but the cutting waste is removed. The stem tips fall down due to their own weight and tilted posture, and fall onto the surface of the tilted cut section cover 36. Slide down and fall along. As a result, cutting chips fall onto the cutter 4 and inside the pretreatment device A. There is no need to lower the cutting material, and there is no need to remove cutting debris.

A guide portion 37 is formed, and the guide portion 37 is not inserted into the cutter cover portion 36a. An introduction part 37a with a V-shaped opening is formed, and the lower side of the part for seedling movement is cut by the stem tip cutter 4. A slit-shaped guide groove 37b is formed toward the seedling cutting part to form a terminal end. .

0012 Behind the rush seedling pretreatment device A, there is a cutting, unraveling, and stretching process performed by the device A. (Pre-treatment) The strip seedling making machine T that forms continuous strip seedlings from desired seedlings is removable. It is connected to the. The basic structure of the belt-shaped seedling production machine T was previously disclosed in Japanese Patent Application No. No. 210646 and utility model registration application filed on March 8, 1991 (reference number NZ It is almost the same as the application filed in No. 642), so the detailed explanation is omitted and the summary is given below. I will explain.

[0013] Reference numeral 19 is a seedling carrying belt of the belt-shaped seedling manufacturing machine T, and 20 is the seedling carrying belt. This is a root alignment belt that rotates in synchronization with the belt 19. The root alignment belt 20 carries the root alignment. Only the feeding surface 20a is exposed and covered with a safety cover 21. Seedling carrying belt 1 Above the transporting seedling stem end direction of No. 9 is a preliminary seedling stand 22 in which pretreated seedlings are stored in advance. are arranged over approximately the entire length of the seedling arrangement section 28, which will be described later, and are located on the lower side in the transport direction. is equipped with a seedling holding belt 23, a stem cutter 24, and a band-shaped seedling manufacturing section 25. Ru. 26 This is a tape that connects rush seedlings in a continuous band. Seedling carrying belt 1 9 or the terminal end of the guide rods 17 and 18 to the starting end of the seedling holding belt 23 Until the end of the process, the roots of the supplied seedlings are arranged, the seedlings are lined up, and the insufficient seedlings are replenished. The front section (right side in Figures 1 and 2) is where the worker is positioned. This is a worker space 29 where the worker will be placed.

[0014] As shown in FIG. 6, the safety cover 21 has its tip inserted into the back side of the root alignment belt 20. is placed in an inverted L shape so that the top surface and front side cover the top surface and front side of the root alignment belt 20. The shape is bent in cross section, and downward insert pins 21a protrude from the center left and right ends of the inside. has been done. In contrast, the machine frame 11 to which the root alignment belt 20 is attached A support pipe 21b is provided on the side to protrude upward, and supports the insertion pin 21a. The cover 21 is removably inserted by inserting it into the boot pipe 21b. It has a structure that allows it to be attached.

[0015] And between the root alignment conveying surface 20a of the state root alignment belt 20, the root part of the seedling P is Guide while accommodating the bulge, and create a gap between its lower end and the root alignment conveying surface 20a. Guide plate 3 that allows mud and debris to fall from 31 due to its own weight and vibration when arranging seedlings. 2 is fixed to the fuselage frame 11 side and extends over approximately the entire length of the seedling arrangement section 28. It is set up as follows.

[0016] In this belt-shaped seedling manufacturing machine T, the seedling conveying surface of the seedling carrying conveyor belt 19 is on the rhizome side of the conveyed seedlings. horizontal plane H. with the stem side at the lower level and the stem end at the higher level. Back side inclination angle α = approximately 30 degrees with respect to L The tilted seedlings being conveyed are made to surely come into contact with the root alignment belt 20. As shown in FIG. 6, the preliminary seedling stand 22 has a back plate that has an angular cross section when viewed from the side. 22a and a bottom plate 22b, and the inclination angle β on the back side of the back plate 22a is as described above. The angle of inclination α on the back side of the seedling carrying conveyor belt 19 is larger than that of about 60 degrees. The bottom plate 22b is formed in a standing state in front, and the bottom plate 22b becomes more horizontal, and the bottom plate 22b becomes more horizontal. The front end of 2b should be as close as possible to the upper end (rear end) of the seedling carrying belt 19. It has become. Therefore, for the worker in worker space 29, it is difficult to The seedling mounting surface of the root 19 and the spare seedling stand 22 face each other at a near right angle in the direction of the shoulder or arm. This makes it easier to perform work, especially when taking out and replenishing seedlings from the reserve seedling stand 22. It becomes easier. On the other hand, in the pretreatment device A, the transported seedlings are placed on a horizontal surface H with the rhizomes facing downward. It is arranged at an angle so that it is conveyed at about 45 degrees with respect to L. Therefore strip seedling making machine The inclination angles of the seedling transport surfaces of T and pretreatment device A are approximately 15 degrees apart. They are connected integrally, and the roots are aligned so that the height of the lower part of the transported seedling in the direction of the stem remains constant. The position of the root alignment conveyance surface 20a of the belt 20 is such that it is discharged from the delivery rolls 16, 16. It is made to approximately match the bottom height of the seedling.

[0017] In addition, in the state shown in FIG. 3, the seedling carrying belt 19 of the strip seedling manufacturing machine The direction in which seedlings are conveyed between station A and conveyor B is arranged to approximately coincide with the horizontal plane. As shown in the line X-X in FIG. Raise the upper side of the pre-processing device A so that γ=approximately 30 degrees with respect to the transport direction of 9. It may also be tilted vertically. With this configuration, the transported seedlings have their stems tilted at approximately 45 degrees. The seedlings are transferred downward at an angle of approximately 30 degrees, and the seedlings relative to conveyor B are This has the advantage of making it easier to supply.

[0018] Next, the functions of the rush seedling pretreatment device A and the strip seedling manufacturing machine T will be explained. Then, the collective seedlings collected from the nursery are fed through the seedling feeding guide section 37. When it is placed on top of the plant 3a and fed, the underground rhizome first gets caught between the two plant base conveyor belts 3, 3. Then, the stem body is transferred to the stem tip conveyor belts 1, 1 and the intermediate conveyor belts 2, 2. The stalk is held at the starting end and conveyed at a low speed at an angle of about 45 degrees, and the tip of the stem is held in place. The stem tip cutter 4 rotates at high speed at the upper part of the underground stem to cut the stem about 250 mm above the underground stem. cut to length.

[0019] The cut stem tip waste falls backwards in the direction of inclination due to the weight of its tip and is cut by the cutter. -Falls onto the surface of the cover part 36a and directly onto the inclined surface of the cutter cover part 36a It slides down along the back side. The root hairs of the rhizome are removed by the plant conveyor belts 3, 3. During the process of being held and transported, underground rhizomes are removed by the left and right root cutting cutters 5, 5 which rotate at high speed. After cutting to a length of approximately 20 mm downward from the end of the stock conveyor belt 3, The stem part is transferred to the starting end of the decoupling device D, and the stem part is transferred to the stem end conveyor belt 1, 1 and the intermediate conveyor belt. The belt 2.2 continues to be conveyed while being held in two places, upper and lower, and the belt 1, The needle-like protrusions 6 of the endless strips 7, 7 rotating at the same speed as the first class... It moves diagonally through the slits of the guide plates 12, 12 and enters the underground rhizome. It penetrates deeply one after another, and at the intermediate sprocket, the needle-like protrusion 6... rapidly penetrates. It spins around and stretches out the tightly entangled roots, separating the underground rhizomes and unraveling them. cormorant. At that time, the needle-like protrusion 6a of the endless band-like body 7 is a portion corresponding to a new bud above the underground stem. The underground rhizome part where hard underground rhizomes are located and unraveled without too much force. Spatula-like protrusions 6b, 6b are located in the hem, and forcefully unravel the rhizome while cutting it. So After passing through this point, it retreats sequentially and escapes from the slits in the guide plates 12, 12, and immediately after that, It is transferred to the exit belts 15, 15 and conveyed in a strongly clamped state, and almost at the same time The stem body is in a released state, and the sent out underground stem part is sent to the sending rolls 16, 16. Since it is pinched and pulled out at a higher speed than the conveyance speed, the released rhizomes are easily transported by the seedlings. The seedlings are pulled in the feeding direction, expanding and becoming a stretched thin layer of seedlings.

[0020] The thin layer of seedlings discharged from the delivery rolls 16, 16 is The stem end is received and supported by the stem tip receiving guide rod 17, and the stem part is held by the stem holding guide rod 18. The body is guided by the 45-degree tilted posture to the 30-degree tilted posture, and the belt-shaped The seedlings are transferred onto the seedling carrying belt 19 of the seedling manufacturing machine T while being kept in a thin layer. The seedlings It is desirable to arrange the group of seedlings on the conveyor belt 19 in as uniform a layer as possible, so that the roots are aligned. An operator located on the belt 20 side adjusts the thickness appropriately. Seedlings again When the number of groups is insufficient, take out the spare seedlings placed on the stand 22 and place them in the front. The group of seedlings discharged from treatment device A is replenished to align the layers of seedlings, and at the same time, as appropriate. The posture of the seedlings being transported should also be corrected.

[0021] After that, the group of seedlings on the seedling carrying conveyor belt 19 is conveyed to the lower side in the conveying direction, and the seedlings are After being held by the holding belt 23 and having the stem tip cut by the stem cutter 24, , continuous strips are sent to the strip seedling production unit 25 and the underground stems are connected with tape 26. Formed in seedlings.

[0022] In the above embodiment, the pre-treatment device A and the strip-shaped seedling manufacturing machine T are connected together to pre-treat the seedlings. Although we have shown an example in which processing and production of strip seedlings are carried out continuously, it is also possible to do this with a separate device. Needless to say, the present invention can be effectively used even if there is such a problem.

[0023]

[Effect of the idea] Since the cutting section cover of the present invention is constructed as described above, the seedlings can be placed along the guide section. It is smoothly fed while being aligned and in the correct tilted standing position, and it is also cut. In addition to accurately and reliably cutting, cutting waste from the tip of the stem of the seedling can be removed from the tip of the stem in an inclined position. It is easy to dispose of cutting debris because it falls onto the cover surface due to the heavy weight and slides down on the cover. This has the effect of preventing it from falling into the processing operation section inside the cover.
