In the slide roll type feeding device, a “strip stop mechanism” that stops feeding only an arbitrary strip during the operation is also required.
The present invention provides a slide roll type feeding device which is capable of adjusting and moving between the strips in the slide roll type feeding device and in which the stripping mechanism is juxtaposed.
In addition, the feeding amount adjusting device in the slide roll type feeding device has a simple structure and is provided integrally with the stopper device.

  The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

  According to a first aspect of the present invention, in the slide roll type feeding device provided with the bar stop mechanism, a hole through which the shaft passes is provided in a part of the feeding portion case that houses the feeding roll, and the feeding drive shaft is fitted into the hole. A striking clutch is disposed on the feeding drive shaft inside the feeding portion case at a portion for transmitting power to the feeding roll, and the striking clutch is disposed on the feeding drive shaft outside the feeding portion case. The stop clutch operating part for connecting and disconnecting is arranged.

  According to a second aspect of the present invention, in the slide roll type feeding device according to the first aspect, the feeding drive shaft is a cylindrical shaft, and a slidable support shaft penetrating through an adjacent feeding device unit is provided inside the feeding drive shaft. It is slidable to the left and right and fitted in an engaged state, and the feeding drive shaft and the hooking clutch are integrated with the case of the feeding part, so that if the feeding part is moved, the threading mechanism slides together. It is comprised so that it may do.

  According to a third aspect of the present invention, in the slide roll type feeding device according to the first or second aspect, the feeding amount is adjusted outside the feeding portion case and on the side provided with the strut stopping clutch operating portion. The feed amount adjusting drive gear and the feed amount adjusting gear are arranged to mesh with each other.

  According to a fourth aspect of the present invention, in the slide roll type feeding device according to the third aspect, the feeding amount adjusting gear is supported while being screwed on a male screw portion of a screw shaft that is pivotally supported by a part of the feeding portion case. And the feed amount adjusting drive gear is configured to mesh with the feed amount adjusting drive gear so that the feed amount adjusting gear rotates to the right and left by rotating in the engaged state. With this rotation, both the feed amount adjusting gear and the sliding side feeding roll slide in the left-right direction, and the feeding amount is adjusted between the non-sliding side feeding roll and the sliding side feeding roll.

  As the effects of the present invention, the following effects can be obtained.

According to the first aspect of the present invention, a hook clutch is provided in a portion that transmits power to the slide roll in the feeding portion case, and the hook clutch operating portion for connecting / disconnecting the hook clutch is provided on the feeding drive shaft. In addition, since it is provided outside the feeding portion case, the structure of the hooking clutch and the hooking clutch operating portion can be simplified.
By integrating the clutch mechanism with the feeding portion, the striking mechanism can be moved together by moving the feeding portion.

  Since it is configured as in claim 2, a plurality of slide roll type feeding devices in which a plurality of units of slide roll type feeding devices are arranged side by side so as to be slidable on the support rod, the adjustment mechanism between the strips is simply configured. It was possible.

  Since the feed amount adjusting device constituted by the feed amount adjusting gear and the feed amount adjusting drive gear is arranged in the portion where the streak clutch operating portion outside the feed portion case is arranged, it is simplified. According to the configuration, the stapling clutch operating portion and the feeding mechanism can be arranged in an overlapping manner.

Since it comprised like Claim 4, the feeding amount adjustment mechanism arrange | positioned inside and outside a feeding part case can be simply comprised by the screw shaft supported by the feeding part case, the feeding amount adjustment gear, and the sliding side feeding roll. It is a thing.
Further, by making the feed amount adjusting drive gear wide, it is possible to slide the feed amount adjusting gear and the sliding side feed roll to the left and right.
In addition, by adopting the structure of the present invention, it is a versatile feeding section that is “accuracy of feeding amount”, “securing the shape of the feeding material”, “adjustment of striations”, “adjustment of all opening degrees”, “possible to stop”. It is what.

Sectional drawing of the feed amount adjustment | control part of the state which removed the non-sliding side feeding roll and the sliding side feeding roll.

  In the powder and granular material feeding device, particularly required performances are “feeding accuracy”, “spot seeding accuracy”, and “shape securing accuracy”. In other words, the “feeding accuracy” that is the accuracy of whether the feeding amount is constant, the “spreading accuracy” that is the accuracy of feeding the feeding material intermittently at a certain distance, and the initial shape of the feeding material. “Shape securing accuracy” that does not hurt or deform is required, but these accuracy are contradictory items that are likely to affect the other if one is excessively determined.

  In order to improve the “spotting accuracy”, a method of holding the feed with a guide until just before discharging from the roll is often used. However, since the feed material continues to be sandwiched between the roll groove and the guide for a long distance and time, the feed material is cracked when the feed amount is large, and the coating material is coated when the coating material is coated. A lot of peeling occurs.

  In order to improve the accuracy of the number of grains of the feed, which is “feeding accuracy”, a method of scrubbing the feed overflowing from the roll groove with a brush or the like is used. In this case as well, scraping the overflowing part may cause cracking or peeling of the feed, and wear on the scraped brush, etc., requiring labor and expense for parts replacement, etc. It becomes. In addition, there are various feed objects in the feed, and the particle sizes thereof are different. Since the amount of feed varies depending on the situation, it is necessary to be able to change the opening, which is the size of the roll groove, but when the number of strips increases, it takes time and labor to adjust the amount of feed. .

  For this reason, a roll type seeder equipped with a mechanism for adjusting the opening of all the strips at a time is also known, but there is also a difference in solids due to the accuracy of parts, so there is also a mechanism that can be adjusted individually. is necessary. In addition, since the interval between the seeding lines varies depending on the feed, it is necessary to provide a “stitch adjusting mechanism” that allows the entire feeding part to move. In addition, special machines such as direct sowing of paddy rice straw have disclosed a technique that uses a full-row opening adjustment mechanism and a streak mechanism, but the streak is fixed and strut adjustment is impossible. It was.

  Next, in FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the overall configuration of the slide roll type feeding device will be described. In the drawing, the directions of the front-rear direction (F · B), the left-right direction (L · R), and the up-down direction (U · D) are shown in FIG.

In addition to the function of adjusting the feeding amount at the same time, a mechanism for automatically performing fine adjustment is provided for each slide roll type feeding device to correct and adjust the feeding amount.

  In FIG. 5, as shown in the coupling portion between the connecting drive shaft 14 and the feed amount adjusting drive gear 16, the engaging portion of the feed amount adjusting drive gear 16 and the connecting drive shaft 14 is configured to be detachable manually. Then, after the engagement state of the connecting drive shaft 14 and the feed amount adjusting drive gear 16 is released, the feed amount adjusting drive gear 16 or the feed amount adjusting gear 15 is manually rotated, thereby the one slide roll. It is possible to individually adjust the feeding amount of only the type feeding device. Thereby, it is comprised so that the variation in the amount of feeding between several slide roll type | formula feeding apparatuses can be corrected.

  A biasing spring 16b is always fitted in the spring fitting hole 16c of the feed amount adjusting drive gear 16, and the constantly biasing spring 16b is engaged with a hexagonal shape or the like of the feed amount adjusting drive gear 16. The hole 16a is pressed toward an engagement protrusion 14a such as a hexagon provided on the connection drive shaft 14. Therefore, the engagement hole 16a and the engagement protrusion 14a are always pressed by the biasing spring 16b and are in the engaged state, and the feed amount adjustment drive shaft 21, the connection drive shaft 14, and the feed amount adjustment drive gear 16 are always in the engaged state. However, when the operator pulls the feed amount adjustment drive gear 16 outwardly at all times against the biasing spring 16b, the engagement hole 16a and the engagement protrusion 14a are engaged. Is released, and the feed amount adjustment drive gear 16 and the feed amount adjustment gear 15 can be manually rotated. Thereby, the feeding amount of each of the plurality of slide roll type feeding devices can be adjusted by finely adjusting the feeding amount for each piece.

  Further, the feed amount adjusting gear 15 is supported in a state of being screwed to a male screw portion 17 a portion on the outer periphery of the screw shaft 17 fixed to the feeding portion case 2 side. By the meshing, the feeding amount adjusting gear 15 rotates, and the sliding side feeding roll 10 loosely fitted to the feeding amount adjusting gear 15 slides left and right. That is, the feeding amount adjusting gear 15 rotates around the male screw portion 17a of the screw shaft 17 integrated with the feeding portion case 2 while being screw-coupled with the female screw portion 15a. Screw feeding to the right is performed. By this screw feeding, the sliding-side feeding roll 10 that is loosely engaged with the outer periphery of the feeding amount adjusting gear 15 moves to the left and right, and the sliding-side feeding that is inserted into the groove of the non-sliding-side feeding roll 9. The distance between the protrusion 10a of the roll 10 and the roll groove 9a of the non-sliding side supply roll 9 is changed, and the adjustment of the supply amount is performed.

  Further, in the feed amount adjusting mechanism of the slide roll type feeding device, the feed amount adjusting drive gear 16 is normally set to maintain the meshing state regardless of the left-right movement for adjusting the feed amount of the feed amount adjusting gear 15. Are constructed in different wide gears. The wide width is configured such that the distance required for adjusting the feeding amount is wide between the protrusion 10a of the sliding-side feeding roll 10 and the roll groove 9a of the non-sliding-side feeding roll 9. It has been done.

  Further, in the feed amount adjusting mechanism of the slide roll type feeding device, the bearing support opening 2b of the feed amount adjusting drive gear 16 supported by the feeding portion case 2 is for driving the non-sliding side feed roll 9. It is eccentric with respect to the position of the bearing support opening 2a of the feeding drive shaft 5.

  Further, in the feeding amount adjusting mechanism of the slide roll type feeding device, the assembling of the slide roll portion constituted by the non-sliding side feeding roll 9 and the sliding side feeding roll 10 to the feeding portion case 2 is performed in the feeding portion case 2. After insertion from the hole opened on the side surface, the hole is closed to constitute a sandwich structure. That is, an opening is provided in the right side surface of the feeding portion case 2, and the opening is configured to be closed by the screw shaft mounting plate 32. The screw shaft mounting plate 32 includes detachable portions 22 and 23 at the upper and lower positions, and is configured to be engaged and fixed to the locking portions 17 c and 17 d of the outer end portion of the screw shaft 17. The detachable portions 22 and 23 are fastened and fixed by one-touch locking members 34 and 35 protruding from the feeding portion case 2.

  Then, the screw shaft mounting plate 32 is fixed to the feeding portion case 2 by the detaching portions 22 and 23 protruding from the feeding portion case 2, and the screws are attached to the detaching portions 22 and 23 via the locking portions 17c and 17d. The shaft 17 is configured to be fixed. In this way, the feeding amount adjusting portion 4 is assembled and fixed to the right side surface of the feeding portion case 2. In this configuration, the screw shaft 17 that is integrally supported with the feeding portion case 2 protrudes into the feeding portion case 2 and is inserted from the opposite side of the feeding portion case 2 to rotate. It is aligned with the heart and is externally fitted.

  A male screw portion 17a is bored on the outer periphery of the screw shaft 17, and is screwed in a state of being screw-fitted with a female screw portion 15a provided inside the feed amount adjusting gear 15. With this configuration, with respect to the screw shaft 17 that cannot move left and right, the feed amount adjusting gear 15 that is supported by the feed portion case 2 so as to be slidable to the left and right moves in the left-right direction by the pitch of the screw. The sliding-side feeding roll 10 that is loosely fitted to the feeding amount adjusting gear 15 and that is locked to the left and right is slid on the screw shaft 17 of the feeding amount adjusting gear 15 and is moved to the non-sliding side feeding roll 9. On the other hand, it is configured to be movable left and right.

  The rotation of the feed amount adjusting gear 15 is rotation for adjusting the feed amount from the feed amount adjusting drive shaft 21, but the sliding side feed roll 10 is non-slidingly engaged with the roll drive shaft 8. Along with the rotation of the moving side feeding roll 9, the roll groove portion 9a of the non-sliding side feeding roll 9 for adjusting the feeding amount and the projection portion 10a for adjusting the feeding amount of the sliding side feeding roll 10 are engaged. Therefore, the rotation of the roll drive shaft 8 is transmitted as the rotation of the sliding side feeding roll 10 via the non-sliding side feeding roll 9.

  The screw shaft 17 for adjusting the feeding amount includes a portion inserted inside the feeding portion case 2 and a portion for fixing to the outside of the feeding portion case 2. That is, the male screw portion 17 a of the screw shaft 17 needs to be fixed at a position protruding inside the feeding portion case 2, and the left end of the screw shaft 17 is inserted from the left side of the feeding portion case 2. The roll drive shaft 8 is loosely fitted to the tip.

  In order to fix the screw shaft 17 in this position, the right side of the screw shaft 17 protrudes beyond the feed amount adjustment gear 15 to the outside of the feed portion case 2, and this portion is formed in the feed portion case. 2 is provided with upper and lower locking portions 17c and 17d. The screw shaft 17 can be removed from the feeding portion case 2 by releasing the locking state of the locking portions 17c and 17d. Detachable portions 22 and 23 from which the screw shaft 17 can be detached are projected from the feeding portion case 2 at the portions of the locking portions 17c and 17d. The detachable parts 22, 23 are constituted by one-touch detachable parts 22, 23. By simply detaching the screw shaft 17 from the feeding part case 2, the feeding amount adjusting part 4 can be easily cleaned and maintained. Is possible.

  Since the non-sliding side feeding roll 9, the sliding side feeding roll 10 and the screw shaft 17 constitute the part of the feeding amount adjusting unit 4, the adjustment of the slide roll is performed by adjusting the feeding amount. The combination of the gear 16 and the feed amount adjustment gear 15 makes it possible to dispose the drive gear for adjustment at a position shifted from the rotation axis of the roll. Thus, one feed amount adjusting drive shaft 21 can be passed through the connecting drive shaft 14 for driving 16. By rotating the feed amount adjusting drive shaft 21, it is possible to adjust the opening degree of a multi-slide roll type feeding device unit at a time. Further, since the drive shaft and the feeding portion are not fixed, the feeding portion can be moved.

  As disclosed in FIGS. 1 to 5, an entrance-side opening 37 that is placed on a hopper and communicates with the popper is opened on the upper portion of the feeding portion case 2, and the entrance-side opening 37. Inside, the entrance capsule 1 is configured to be fitted and fixed.

The lower part of the popper is placed and can be fixed with a clasp. The remaining amount outlet opening 1c is formed on the bottom surface of the inlet capsule 1 and the remaining amount outlet opening 1c is overlapped with the remaining amount outlet opening 1c on the bottom surface of the portion of the feeding portion case 2 where the inlet portion capsule 1 is inserted. The extraction opening 2c is opened.

  The remaining amount extraction opening 1c and the remaining amount extraction opening 2c are usually covered with a lid, but when the supply is changed, the remaining amount of the supply inside the slide roll type supply device is determined. When it is necessary to take out the whole, the lid is removed and the remaining amount can be taken out. As shown in FIGS. 9 and 10, a support portion of the feeding drive shaft 5 is opened upward at the front portion of the feeding portion case 2 where the portions of the feeding portion case 2 and the capsule fixing body 3 are arranged. It is configured as a space, and a streak clutch 6 and a streak clutch operating portion 7 are disposed on the feeding drive shaft 5.

  Further, after the slide roll type feeding device unit is moved on the slidable support shaft 24 and slid on the mounting rod of the work implement mounting device, the gap is confirmed and fixed. It is configured as follows. The slidable support shaft 24 and the feeding drive shaft 5 are configured to slide but not to be fixed.

  The streak clutch 6 is disposed on the feeding drive shaft 5, and includes a fixed side engaging claw 6 a, a sliding side engaging claw 6 b, a clutch biasing spring 6 c, a stunt clutch operating unit 7, It is constituted by a claw removal 7a and the like. A sliding side engaging claw 6 b is engaged with the outer periphery of the feeding drive shaft 5 constituted by a cylindrical shaft, and the fixed side engaging claw 6 a is integrated with the feeding drive shaft side gear 13 via the cylindrical shaft 33. It has become. Normally, it rotates integrally with the payout drive shaft side gear 13, but is loosely fitted to the payout drive shaft 5 so as to be free.

  From this state, by rotating the operation knob 7b of the latching clutch operating portion 7, the loosely fitted collar 6d is pushed by the urging force of the clutch urging spring 6c, and the sliding side engaging claw 6b and the fixed side are fixed. The engaging claw 6a is pressed to maintain the engaged state. The engagement / disengagement claw 7a is configured so that the engagement state of the hooking clutch 6 is maintained. When the operation knob 7b is operated to the engagement side, the engagement / disengagement claw 7a presses the clutch biasing spring 6c. The locked state is locked to prevent the stray clutch 6 from coming off. When the operation knob 7b is operated to the release side, the engagement / disengagement claw 7a is pushed by the sliding engagement claw 6b so that the strut clutch 6 can be disengaged, and the power of the slidable support shaft is transmitted to the feeding drive shaft 5. It is configured not to be.

  The feeding drive shaft 5 that supports the hooking clutch 6 and the hooking clutch operating portion 7 is inserted from a side into a drilling hole opened in the side surface of the feeding portion case 2, and the feeding driving shaft 5 is fed to the feeding portion. A streak clutch 6 is disposed at a portion disposed in the upper opening of the case 2. The portion of the strut holding clutch operating portion 7 is configured on the feeding drive shaft 5 protruding from the right side surface of the feeding portion case 2, so that a hopper or the like is placed on the upper side in the support state of the feeding drive shaft 5. Even after being fixed, the stapling clutch operating portion 7 can be operated from the outside of the feeding portion case 2.

  On the right side surface of the feeding portion case 2, a feeding amount adjusting portion 4 is configured. The feed amount adjusting unit 4 includes a feed amount adjusting gear 15 and a feed amount adjusting drive gear 16 which are screw-supported by a screw shaft 17. The feed amount adjusting unit 4 has been described above.

  As shown in FIGS. 1 and 2, on the side surface of the feeding portion case 2, a connecting drive shaft of a feed amount adjusting drive gear 16 for driving the feed amount adjusting portion 4 below the feed drive shaft 5. A bearing support opening 2b for supporting 14 is also provided. In FIG. 2, the connection drive shaft 14 has a hexagonal hole opened therein, and a feed amount adjustment drive shaft 21 fitted in common between the plurality of left and right slide roll type feed devices is provided inside the connection drive shaft 14. When inserted, the plurality of feed amount adjusting units 4 can be adjusted at the same time, and the connecting drive shaft 14 of the feed amount adjusting drive gear 16 slides left and right on the feed amount adjusting drive shaft 21 to adjust the interval. The slide roll type feeding device is configured to allow left and right movement.

  Next, the feeding mechanism will be described with reference to FIGS. In the slide roll type feeding device, the feeding mechanism of the slide roll type feeding device is made to be a pumping type, so that the feeding material that cannot fit into the groove falls by its own weight, so that a large amount of feeding material does not go into the groove unnecessarily. It is composed. When the feed comes into the upper part of the roll, there is a brush, so that the feed coming in more than the groove is scraped off. Thereby, the number accuracy is improved. Since the pumping system does not enter the roll groove portion 9a in a large amount, the amount that can be slid by the upper roll brush 25 is reduced, and cracks in the feed and peeling of the coating material are reduced. Further, it is possible to suppress wear of the brush.

  Next, after the feed is positioned above the roll, the shielding plate disappears and the groove width increases. As a result, the feed material that fits into the groove moves toward the expanded space, and a margin in the groove is created. Even when passing through the portion of the outer peripheral guide 26 behind the brush, a margin is provided between the outer peripheral guide 26 and the crack, and coating peeling is reduced. In addition, since the feed is arranged in the direction perpendicular to the traveling direction, the landing shape on the field, that is, the length in the traveling direction is shorter than usual, and the outer periphery guide 26 that improves the seeding accuracy is located upward. The pivot part 26a is pivotally supported, and the lower part can be turned to the turning side.

  By holding the feed to the discharge point by the outer peripheral guide 26 behind the brush, the feed can be released to the field in a lump. It leads to improvement of spot seeding accuracy. By making the guide not swingable but swingable, it is possible to reduce cracks in the feed and the peeling of the coating material caused by friction. The adjustment of the slide roll is a combination of the feed amount adjustment drive gear 16 and the feed amount adjustment gear 15, and the axis of the drive gear for adjustment and the feed amount adjustment drive shaft 21 is rotated by the slidable support shaft 24 of the roll. It is possible to dispose at a position shifted from the axis line, and it is possible to pass a single drive shaft in the case of multiple strips.

  By rotating this shaft, it becomes possible to adjust the opening degree of multiple stripes at once. Further, since the drive shaft and the feeding portion are not fixed, the feeding portion can be moved. As described above, it is possible to configure a feeding portion that satisfies “improvement of spot seeding accuracy”, “improvement of grain number accuracy”, and “reduction of cracking and peeling”. Moreover, it can be set as the slide roll type | formula feeding apparatus which can move between stripes, and has an all-strand opening degree adjustment mechanism and a string stop mechanism.

  The problem is solved by a roll having the following structure. As disclosed in FIG. 6 and the like, a shielding plate insertion groove 9b of the shielding guide plate 18 is provided in the middle of the roll groove portion 9a of the non-sliding side feed roll 9 that normally communicates with one another. By rotating the non-sliding side feeding roll 9 with the shielding guide plate 18 fitted in the fitting groove 9b, the capacity of the feeding portion in the portion of the inlet capsule 1 is limited. The fixed-side feeding roll 9 is provided with a drive shaft hole 9c into which the roll drive shaft 8 is fitted in an engaged state.

  Further, the roll groove portion 9a is separated by the shielding plate insertion groove 9b, and the shielding guide plate 18 is inserted into the gap. However, the shielding guide plate 18 is disposed only about half on the rear side with respect to the roll rotation direction, and does not extend to other portions. The roll groove portion 9a in the range where the shielding guide plate 18 exists has half of the entire groove width restricted by the shielding guide plate 18, and the movement of the feed is impossible.

  A roll brush 25 is disposed above the roll, above the fitting portion where the roll groove 9a of the non-sliding side feeding roll 9 and the protrusion 10a of the sliding side feeding roll 10 mesh with each other. . The roll brush 25 is not fixed and is biased by a spring or the like from above, and has a structure capable of moving up and down. Further, since the shielding guide plate 18 does not exist in front of the roll brush 25 in the roll rotation direction, the shielding guide plate 18 disappears in the shielding plate insertion groove 9b, and the left and right roll groove portions are widened. The feed can spread within 9a. That is, the roll groove portion 9a can be expanded immediately before reaching the lower portion of the limit guide projection 20, which is the end portion of the roll groove width and the shielding guide plate 18.

  The outer peripheral guide 26 that is made of iron, resin, sponge, neurite seal, or the like, just behind the brush, is connected to the roll groove 9 a of the non-sliding side feeding roll 9 and the protrusion of the sliding side feeding roll 10. It arrange | positions on the outer periphery of the part which the part 10a meshed | engaged. The feeding position of the feed from the hopper arranged above the inlet capsule 1 is not above the non-sliding side feeding roll 9, but the outer periphery around which the non-sliding side feeding roll 9 and the sliding side feeding roll 10 rotate. From the side or diagonal position, the feed is configured to be pumped up into the roll groove 9a. And, the amount of the feed in the pumped-up state is the terminal portion of the shielding guide plate 18, so that a certain amount or more does not enter the staying space 27 that can be positioned before reaching the starting end portion of the roll brush 25. A shutter plate 19 is attached to the inlet capsule 1 with a fastener 19a.

  The structure of the inlet capsule 1 is configured such that the inlet capsule 1 can be fitted in a space between the feeding case 2 and the upper hopper. The entrance capsule 1 includes a portion where the shutter plate 19 described above can be attached and a portion where a shielding guide plate 18 fitted into the shielding plate insertion groove 9b formed in the non-sliding side feeding roll 9 is attached. By the shielding guide plate 18, the feed material that passes through the inlet capsule 1 from the hopper, passes under the shutter plate 19, and enters the stay space 27 is placed inside the left inlet capsule 1. A restriction guide projection 20 is provided to move and guide the center position from the side.

  The restriction guide protrusion 20 is formed integrally with the inlet capsule 1. Further, the inlet capsule 1 is provided with a fastening diagram in which the shielding guide plate 18 and the shutter plate 19 can be fixed by a fastener such as a bolt as described above. When the plate 18 or the shutter plate 19 is attached or when the limiting guide protrusion 20 is formed integrally with the feeding portion case 2, it can be fitted inside the feeding portion case 2 in order to obtain ease of assembly and maintenance. It is constructed as a separate body.

  In the space between the feeding portion case 2 and the hopper, a capsule fixing body 3 that prevents the inlet portion capsule 1 from coming out is provided from above in a state where the inlet portion capsule 1 is fitted. The capsule fixing body 3 is configured such that the lower part of the hopper is fixed.
