Description

  The present invention relates to a granular material feeding machine that feeds granular materials such as fertilizers and seeds to a field by a predetermined amount, and in particular, to a seeding machine or a fertilizer machine that performs fertilization and sowing while being mounted on a tractor or a management machine and moved. The present invention relates to a hopper structure of a provided granular material feeding machine.

Conventionally, there is known a fertilizer sowing machine that is mounted on a vehicle such as a tractor or a management machine and that can perform fertilization and sowing simultaneously. The fertilizer sowing machine includes a fertilizer that includes a fertilizer hopper and a feeding portion. An apparatus and a sowing apparatus comprising a sowing hopper and a feeding portion are arranged in parallel in the front and rear, and the entire fertilizer sowing machine has a compact configuration (for example, Patent Document 1) is known. And when performing either work of fertilization or sowing using the hopper and feeding part of such an integrated fertilizer seeding machine, the same granular material to be put into both hoppers, A predetermined granular material can be fed to a plurality of strips by a feeding machine. Furthermore, when using such an integrated fertilizer or sowing machine, the feeding device for fertilization and sowing is kept as it is, and only the hopper is used in order to improve workability such as charging of granular materials into the hopper. As a single hopper (hereinafter referred to as “single hopper”), the capacity of the hopper is increased.
JP-A-62-239907

  By the way, the fertilizer or seeder is attached to the vehicle and performs the work while being pulled. When the turn is completed, the work is lowered and landed on the field, and then the work is started again. At the time of turning the vehicle, the hopper is also largely inclined at the same time, and when the remaining amount of particulate matter in the hopper is small, the particulate matter is greatly biased toward the tilting side of the single hopper. Therefore, in the hopper provided separately for each feeding part, even if the hopper is largely inclined when the vehicle turns, the lower spaces of both hoppers are filled with substantially the same amount of particulate matter. The granular material supply to the inside of the unit can be completed at substantially the same timing. However, in a single hopper in which a large capacity is achieved by combining a plurality of hoppers, as shown in FIG. When one hopper 1 rotates by an angle 7 and rises to the tilted position 6, the horizontal position 5 has a granular shape that is present on the front and rear communication ports 1 a and 1 b opened at the bottom of the single hopper 1 with substantially the same thickness. The object also flows in the tilting direction 8 at the tilting position 6, and the front communication port 1a is covered with a large thickness, while there are almost no particulate matter on the rear communication port 1b. Therefore, even if the work is started again after returning to the horizontal position 5 after the vehicle turns, if the granular material has poor fluidity, it cannot be restored to its original state, and the granular material 4 covering the communication ports 1a and 1b. Therefore, the amount of the granular material supplied to the feeding units 2 and 3 is different, and the supply of the granular material from the feeding units 2 and 3 to the respective strips cannot be completed at substantially the same timing. Therefore, there is a problem that unsowed or unfertilized portions are generated depending on the stripe, and the productivity and quality of the crop are lowered.

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.
In Claim 1, it has a hopper (36) which stores a granular material, and a feeding device (38) connected to the space (36a) below the hopper (36), and the feeding device (38) It comprises a front feed portion (60) and a rear feed portion (61) arranged side by side along the front-rear direction in which the hopper (36) tilts, and the front feed portion (60) and the rear feed portion In the granular material feeder (15) in which each of the parts (61) communicates with the lower space (36a), the front communication port (72), and the rear communication port (73), the lower space (36a) , partition body for partitioning between the front communication opening (72) and the rear communication opening (73) to (81), provided in said hopper (36) in front Symbol lower space (36a) is a small communicating above Divided into a front compartment space (36e) and a rear compartment space (36f), The front partition space (36e) and the rear partition space (36f) of the capacity are respectively connected to the front feeding portion (60) and the rear feeding portion (61) via the front communication port (72) and the rear communication port (73). ).

  Thereby, when the front feeding roll 63 and the rear feeding roll 69 rotate, the seeds flowing into the front feeding case 62 and the rear feeding case 68 from the lower end of the sowing hopper 36 are transferred into the front roll groove 63a and the rear roll. The seeds that are captured in the groove 69a and conveyed downward, but do not fully enter the front roll groove 63a and the rear roll groove 69a, are scraped off by the front brush 70 and the rear brush 71 during the rotation conveyance, Only a predetermined amount of seeds is supplied to the front feeding part 60 and the rear feeding part 61, and from the lower part thereof to the predetermined positions of the open parts of the left and right grooving disks 51 and 51 via the sowing hoses 43 and 43, respectively. Be sure to sow.

  As shown in FIGS. 2 to 4, a front communication port 72 and a rear communication port 73 are opened forward and backward at the bottom of the sowing hopper 36, and the front communication port 72 and the rear communication port 73 are forwardly fed. In the front feeding case 62 of the part 60 and in the rear feeding case 68 of the rear feeding part 61, they are respectively inserted and fixed from above. A front shutter 74 and a rear shutter 75 are attached above the entrances of the front communication port 72 and the rear communication port 73 so that they can be inserted and removed in the front-rear direction.

  As a result, in the state where both the front shutter 74 and the rear shutter 75 are fully inserted, seeds are not supplied from the sowing hopper 36 to the front feeding unit 60 and the rear feeding unit 61 at all, and the front shutter 74 and the rear shutter 75 are not supplied. In the state where both are pulled out, the sowing hopper 36 is communicated with the front feeding part 60 via the front communication port 72 and with the rear feeding part 61 via the rear communication port 73, and the front feeding part is connected from the sowing hopper 36. 60 and the post-feeding unit 61 are supplied with seeds, and a predetermined amount of seeds can be fed to the field through the sowing hoses 43 and 43. Further, by pulling out only one of the front shutter 74 and the rear shutter 75, switching from two-row sowing to single-row sowing can be easily and quickly performed.

  Further, in the lower space 36a of the sowing hopper 36, upper and lower fixed guides 76 are respectively provided on the left and right side walls 36b and 36c which are substantially in the center in the front-rear direction and are on the boundary line between the front communication port 72 and the rear communication port 73. 77 is fixed, and the upper fixed guides 76 and 77 are arranged to face each other, and each is constituted by two guide plates 76a and 76b, 77a and 77b arranged in parallel. Similarly, lower fixed guides 78 and 79 are respectively fixed to the lower portions of the left and right side walls 36b and 36c. The lower fixed guides 78 and 79 are arranged opposite to each other, and each of the two fixed guides 78 and 79 is arranged in parallel. It consists of a single guide plate 78a / 78b, 79a / 79b.

  Guide grooves 76c, 77c, 78c, and 79c are formed in the gaps of the guide plates 76a and 76b, 77a and 77b, 78a and 78b, and 79a and 79b that constitute the four fixed guides 76, 77, 78, and 79, respectively. Has been. Then, by inserting a plate-like partition 81 according to the present invention from above into the guide grooves 76c, 77c, 78c, 79c and sliding it downward, the partition 81 is detachable in the sowing hopper 36. It can be fixed to.

  As shown in FIGS. 2, 4 to 6, the partition 81 is composed of a partition lower part 81a whose both side edges are parallel to each other and a partition upper part 81b whose both side edges are opened upward, and the lower space 36a It is formed in substantially the same shape as the inner cross section. A plurality of convex portions 81c are provided on the front and rear surfaces at substantially the center of the left and right sides of the partition upper portion 81b so as to extend horizontally in the vertical direction, and the partition 81 is not slid by sandwiching the plurality of convex portions 81c from the front and rear. In this way, it can be slid and mounted on the fixed guides 76, 77, 78, 79 after being securely gripped.

  Thus, the fixed guides 76, 77, 78, and 79 are gripped and inserted into the sowing hopper 36 from the charging port 36 d and the narrow partition lower portion 81 a of the partition 81 is placed downward. By sliding the partition 81 along the guide grooves 76c, 77c, 78c and 79c, the partition 81 can be detachably attached to the lower space 36a, and the lower space 36a can be connected to the front and rear communication ports 72, 73 is surely partitioned between the two.

  As shown in FIG. 7, when such a partition 81 is provided in the sowing hopper 36, the lower space 36a is partitioned into a front partition space 36e and a rear partition space 36f that communicate with each other upward, The spaces 36e and 36f are communicated with the front feeding portion 60 and the rear feeding portion 61 through the front communication port 72 and the rear communication port 73, respectively. For this reason, in the sowing hopper 36 in the horizontal position 82, the seed 85 is stored separately in two places, a small compartment front space 36e and a rear compartment space 36f. Even if the 36 rotates by an angle 84 and rises to the tilting position 83, the seeds 85 in both the compartment spaces 36e and 36f only flow slightly in the tilting direction 86, and both the communication ports 72 and 73 are entirely exposed. Will be covered by the seed 85 to the same extent.

  That is, it has a sowing hopper 36 that is a hopper for storing seeds 85 that are granular materials, and a seed feeding device 38 that is a feeding device that communicates with the lower space 36a of the sowing hopper 36. The front sowing hopper 36 is composed of a front feeding portion 60 and a rear feeding portion 61 that are a plurality of feeding portions arranged in parallel with the tilting direction 86 that is the direction in which the sowing hopper 36 tilts. In the seed feeding machine 15 which is a granular material feeding machine provided with a front communication port 72 and a rear communication port 73, each of which is a communication port between each of the rear feeding units 61 and the lower space 36a, the lower space 36a is communicated with the front communication port. Since the partition body 81 for partitioning between the mouth 72 and the rear communication port 73 is provided in the sowing hopper 36, the lower space 36a is divided by the partition body 81 into a front partition space 36e and a rear partition space. It can be divided into the drawing space 36f. Even if the work progresses and the remaining amount of the seed 85 stored in the sowing hopper 36 decreases, the tractor 10 as a vehicle turns, and the sowing hopper 36 is also greatly inclined together. In addition, the seed 85 is held as it is in the small volume of the front compartment space 36e and the rear compartment space 36f, and does not flow out in the tilting direction 86 of the sowing hopper 36, and the front communication port 72 and the rear communication port 73. The top can be covered with similar thickness. For this reason, when returning to the horizontal state again after turning the tractor 10 and restarting the work, even if the seed 85 has poor fluidity, the front communication port 72 and the rear communication port 73 are connected to the front feeding unit 60 and the rear feeding unit 61. The difference in the supply amount of the seed 85 supplied to each is small, and the supply of the seed 85 from the pre-feeding unit 60 and the post-feeding unit 61 to the respective strips can be completed at substantially the same timing. Can improve crop productivity and quality. In this embodiment, seeds 85 are used as the granular material. However, fertilizers or the like may be used instead of the seeds 85, so that unfertilized portions can be eliminated.

  Since the partition 81 is configured to be detachable from the sowing hopper 36, the partition 81 can be easily detached from the sowing hopper 36, and the seeds 85 are clogged in the front feeding part 60 and the rear feeding part 61. The cleaning work in the case of replacement and the replacement work in the case of replacement with an appropriate partition 81 according to the size and form of the seed can be performed easily and quickly, and the maintainability can be improved. Furthermore, when the particle size is large, such as soybeans, or even if the particle size is low, and the seed 85 has high fluidity, the seed 85 is immediately leveled when the sowing hopper 36 returns to the horizontal position after turning the vehicle. Since the front communication port 72 and the rear communication port 73 are covered with the seed 85 with a substantially uniform thickness, the partition 81 is not necessary. Even in such a case, the partition 81 is simply removed from the sowing hopper 36. It can be applied to various granular materials with the same configuration of the feeding machine.

  Further, the partition 81 is fixed by upper and lower fixing guides 76 to 79 which are fixing members respectively provided on the opposite side walls 36b and 36c in the sowing hopper 36. The partition 81 can be firmly supported by being sandwiched from both side edges by the fixed guides 78 and 79, and the partition 81 is not pushed down by the granular material such as seeds due to vibration or the like during work, and the lower space 36a. Can be reliably partitioned between the front communication port 72 and the rear communication port 73.

  In this embodiment, the partition 81 is detachable as a separate member from the sowing hopper 36. However, the partition 81 may be manufactured by integral molding with the sowing hopper 36, and the lower space 36a is formed in the front space 36a. The configuration is not particularly limited as long as it can be reliably partitioned between the communication port 72 and the rear communication port 73. Thereby, the number of parts which comprise sowing hopper 36 can be reduced, and improvement of assembling property and maintenance nature can be aimed at.

  Further, the partition 81 is plate-shaped in this embodiment, but may be a net or the like as long as it prevents the movement of particulate matter between the partition spaces 36e and 36f. It is not limited.

  In the granular material feeding machine according to the present invention, one hopper is provided for each feeding device composed of a plurality of feeding parts in the front-rear direction, and a plurality of these feeding devices are arranged in parallel in the left-right direction. By providing a common single hopper, the present invention can be applied to a granular material feeding machine in which the workability such as charging the granular material into the hopper is further improved.
