Description

Technical Field

[0001] The invention relates to a feed crushing and mixing technology, and more specifically to a feed mixing production method for animal husbandry. Background Art

[0002] In the current animal husbandry industry, feed costs account for a large part of the total breeding costs, and the quality of feed directly affects the growth rate of livestock and poultry, the quality of meat, eggs and milk, disease resistance, etc. The traditional feed mixing production method has problems such as unbalanced nutrients, low digestibility, and excessive use of additives, which not only affects the healthy growth of animals, but also causes unnecessary burdens on the environment by blindly adding nutrients.

[0003] Most of the existing livestock feeds are directly made of grass, straw, some common cereal crops and fruits, and some fungi, which are directly crushed and mixed by mechanical or manual methods to make these materials evenly dispersed. In practice, all materials are directly crushed and the crushed materials are poured into the mixing equipment together. For example, when performing mechanical mixing, a vertical or horizontal TMR mixer is used for mixing to ensure that the raw materials are uniform. This traditional mixed production method is undoubtedly very efficient. However, due to the different types of these materials, the degree of crushing of some materials, such as corn stalks, is different from that of some cereal crops. Some materials are almost in a powder state after crushing. If they are directly added to crushed materials such as straw, it is difficult to form a stable dispersion uniformity. Even when there is moisture in the straw or forage, several materials in the powder state will form clumps and lumps before the powders are mixed with each other. Finally, they are extremely unevenly dispersed and mixed in the crushed feed such as straw. This part of powdered fine-grained feed is often a key role in the growth and development of livestock, and cannot be equated with ordinary forage straw and other feed that is randomly stirred and mixed. Moreover, this part of feed is also a component that livestock cannot obtain by themselves during daily grazing.

[0004] In addition, the existing feed raw materials are all uniformly crushed by the same crushing equipment and then stirred and mixed. In terms of performance, it is difficult for all types of feed to obtain a good degree of crushing. After all, different feed raw materials only need to be slightly crushed, while a small part must be crushed before they can be better mixed and evenly dispersed in the feed so that livestock can take in a predetermined amount each time they eat. Summary of the invention

[0005] The problem to be solved by the present invention is to provide a mixed production method for animal husbandry feed in view of the above-mentioned deficiencies in the prior art. The method adopts a reasonable combination of feed types, matched with corresponding material crushing or pulverizing processes, and enters the materials into a mixing tower in batches for mixing. This can not only improve the more consistent uniform dispersion of the core feed components, but also ensure the stability of the matching ratio of the core nutrients of the feed.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a method for producing mixed feed for animal husbandry, comprising further fully crushing each group of feed and then mixing, the feed comprising roughage, energy feed and protein feed, wherein the roughage comprises hay and straw, the energy feed comprises corn, barley and sorghum, and the protein feed comprises soybean meal and peanut meal; when crushing the roughage, the roughage is first squeezed by a press to be flattened and crushed, and then put into a rotary crusher, further chopped by a high-speed rotating blade, and stored in a first preparation bin; when crushing the energy feed, corn, barley and sorghum are mixed together, directly crushed into fine particles by a crusher, and stored in a second preparation bin; the protein feed is crushed into powder by grinding and stored in a third preparation bin.

[0007] When mixing materials, the energy feed and the protein feed are first pre-mixed together by means of rotary stirring, and yeast cells are added during the mixing process to allow the yeast cells to be evenly dispersed in the premix formed by the energy feed and the protein feed; the premix is ​​then intermittently conveyed through a transmission chain plate to a vertically installed mixing tower on its left side, and before each introduction of the premix, crushed coarse feed is poured into the mixing tower. After the premix is ​​poured onto the surface of the crushed material in the mixing tower, a stirring shaft axially covered with stirring blades is inserted into the mixing tower for stirring, so that the powdered premix is ​​mixed with the crushed material crushed into strips.

[0008] Furthermore, the premix is ​​discharged downward evenly through a discharge bin, and the transmission chain plate includes a plurality of transmission plates which are hinged end to end in sequence, and the transmission plate is a solid plate with a smooth surface. Before the first transmission plate enters the mixing tower, a gate plate in the mixing tower which is linked to the transmission chain plate seals the bottom of the mixing tower, and the moment each transmission plate enters the mixing tower, it will flip downward due to its own weight, so that the premix is ​​transported into the mixing tower once.

[0009] Furthermore, the stirring shaft can move to above the top of the mixing tower and then move downward. The bottom end of the stirring shaft is cone-shaped. The spiral blades arranged on the stirring shaft can transport the material in the mixing tower axially downward as the stirring shaft rotates. When the material is transported to the gate plate, due to the obstruction of the gate plate, the material is transported upward through the gap channel between the spiral blades and the inner wall of the mixing tower, thereby realizing a circular flow in the vertical direction, so that the premix is ​​evenly dispersed in the crushed material.

[0010] Furthermore, a chassis is provided on the right side of the mixing tower, and a large gear is provided in the chassis. A driving wheel is coaxially fixed to the large gear. The driving wheel transmits a transmission belt through a pair of driven wheels symmetrically arranged on the left and right. The horizontal section of the transmission belt is located below a horizontally arranged support plate, and the support plate is provided with a notch along the length direction. The support plate is used to support the transmission chain plate for sliding. At the bottom of the rear side plate where the last section of the transmission chain plate is hinged, it is fixed to the transmission belt through a connecting column passing through the notch, so that when the transmission belt moves to the left, the transmission chain plate moves to the left, and all the transmission plates of the transmission chain plate fall into the mixing tower one by one.

[0011] Furthermore, the large gear meshes with a small gear below it, and the small gear meshes with a horizontally slidable rack, and the left end of the rack is fixed with the horizontally arranged gate plate; the end teeth at both ends of the rack are horizontally elastically slidably installed on the main body of the rack.

[0012] Furthermore, a slider is fixed at the bottom end of the end teeth, the slider is slidably mounted at one end of the slide groove on the main body, and is elastically connected to the other end of the slide groove through a pressure spring, and the two pressure springs are located between the two end teeth; The starting motor drives the large gear to rotate counterclockwise, the rack moves to the left, the gate plate enters the mixing tower and closes it, and at this time, the large gear is driven by the transmission belt to move the transmission plate toward the mixing tower, but has not yet completely entered the mixing tower. When the gate plate is inserted into the mixing tower, the small gear just engages with one of the end teeth, and because of the elastic telescopic mounting structure of the end teeth, the small gear and the end teeth are in an elastic extrusion contact state, and the small gear continues to rotate so as not to affect the rotation of the large gear; when the last section of the transmission plate falls into the mixing tower, the driving motor reverses, the gate plate withdraws from the mixing tower to realize unloading, and when the gear engages with the other end tooth, similarly, the small gear can continue to rotate so that the transmission chain plate leaves the mixing tower and resets.

[0013] Furthermore, after each transmission plate falls into the mixing tower, the large gear and the discharge bin stop working, and a grinding extrusion disk with grinding teeth is pressed into the mixing tower. A sliding block is elastically and telescopically installed on the right side of the grinding disk. A right-angled trapezoidal wedge block is provided on the upper surface of the sliding column of the sliding block. The inclined surface of the wedge block is used to contact the top wall of an inner sliding cavity in a sliding bar. The top of the wedge block is elastically and telescopically connected to the grinding extrusion disk through a sliding rod. When the sliding block pops out of the side of the grinding extrusion disk and contacts the right side wall of the mixing tower, the sliding bar slides downward under the elastic action, and based on the contact between the wedge block and the inner sliding cavity, the bottom surface of the sliding bar is flush with the bottom surfaces of the grinding extrusion disk and the sliding block, and the bottom surfaces of the sliding bar and the sliding block are both provided with the grinding teeth.

[0014] Furthermore, the method for retracting and resetting the sliding block is as follows: an electromagnet is also provided in the grinding extrusion disk, and the electromagnet is used to attract the sliding bar to move it upward. After the sliding bar moves upward, the sliding block retreats into the grinding extrusion disk under the action of elasticity, and the bottom end of the sliding bar is located on the storage step between the grinding extrusion disk and the sliding block. The electromagnet is immediately energized when the extrusion grinding disk moves upward, so that the sliding block retreats into the grinding extrusion disk.

[0015] Furthermore, the sliding post is axially slidably inserted into the insertion hole in the grinding and extrusion disk, and is connected to the compression spring in the insertion hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the mixed production method for animal husbandry provided by the present invention divides the feed components into three categories, each category is crushed or pulverized by economical and applicable means to obtain a corresponding reasonable material particle size, and then mixed in batches, that is, a two-stage mixing mechanism, after pre-mixing the energy feed and protein feed, the grass feed, straw and other materials that are not easy to crush as the basic material are mixed, so that the energy feed and protein feed that are easy to crush are first evenly mixed together in the form of fine particles, and then mixed with the roughage as the basic material, so as to ensure that the two types of functional feeds can be uniformly mixed in advance in a corresponding proportion standard, and the formed premix can be directly stirred with the roughage, which has lower cost. Even when the premix is ​​mixed with the roughage, there will be a situation of agglomeration and dispersion. Then, compared with mixing with the crushed material of the roughage itself, the distribution of such agglomerates in the roughage is also in a relatively uniform state. Moreover, the content of functional feed itself is much lower than that of roughage. Therefore, this mechanism of crushing or grinding separately and then mixing will undoubtedly greatly reduce the volume and mixing time of the corresponding equipment, and targeted and strict control can be carried out in the crushing and mixing links of key feed types.

[0017] In addition, in the present method, for the transportation of each component feed, especially the transportation of premixes, since the transmission speed of the transmission plate is consistent and the discharge flow rate of the discharge bin is consistent, the amount of premixes poured into the mixing tower by each transmission plate entering the mixing tower will be automatically maintained within a relatively stable range. Therefore, the amount of roughage added to the mixing tower each time can also be fixed. Moreover, since all materials are fed intermittently multiple times and stirred each time, the problem of difficulty in mixing uniformly when a large amount of materials is stirred centrally is avoided, and the stirring volume requirement for the equipment is also smaller.

[0018] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments: like Figure 1As shown, this embodiment specifically introduces a mixed production method for animal husbandry feed. Like the prior art, each group of feed needs to be fully crushed before mixing. Specifically, in this embodiment, the feed includes roughage, energy feed and protein feed. The roughage includes hay and straw, the energy feed includes corn, barley, and sorghum, and the protein feed needs to use soybean meal and peanut meal. Based on the above types of feed, the mixed production process is summarized, that is, when crushing the roughage, the hay, especially the thick plants such as straw, should be squeezed by a press to be flattened, and then crushed. The specific crushing can be minced into shorter thin strips of broken materials, and then put into a rotary crusher, and further chopped by a high-speed rotating blade to shorten the length of its strip structure, and then stored in the first preparation bin for standby. When crushing the energy feed, corn, barley and sorghum are mixed together. These granular materials can be directly crushed into fine particles by a crusher. In order to obtain a smaller particle size, they can be crushed at least twice and then stored in the second preparation bin. In this embodiment, as for the protein feed, because it is mainly some block residues after squeezing, the texture itself has a certain brittleness. Therefore, it can be directly crushed into powder by grinding and stored in the third preparation bin, and a relatively sufficient powdered solid can be easily obtained. When mixing materials, based on the characteristics of the above-mentioned crushed materials, it is recommended to pre-mix the energy feed and protein feed together by rotating and stirring. The two types of feed are small and similar in size, so they can be mixed. Yeast cells are added during the mixing process to allow the yeast cells to be evenly dispersed in the premix formed by the energy feed and protein feed. Avoid mixing the two fine granular feeds directly with the crushed materials after the roughage is crushed. The two fine granular feeds are easily clumped and mixed in the cracks or special cavities of the crushed materials of the roughage, making it difficult for both feeds to be fully dispersed in the mixture. Especially when encountering water, it is easy to clump together, and the dispersion degree of the two feeds is different.After the above-mentioned premixing operation, the premix can be intermittently conveyed through a transmission chain plate 3 to a vertically installed mixing tower 1 on the left side thereof, and before each feeding of the premix, the mixing tower 1 is filled with crushed coarse feed, that is, the coarser feed crushed material is added at this time. After the premix is ​​poured onto the surface of the crushed material in the mixing tower 1, a stirring shaft 13 axially covered with stirring blades is inserted into the mixing tower 1 for stirring, so that the powdered premix and the crushed material broken into short and thin strips are evenly mixed and mixed together to form a mixed feed. Moreover, since the two crushed materials are The two kinds of fine-particle feed, namely energy feed and protein feed, have been evenly mixed into one in advance. Even if some powder is mixed into agglomerates in the roughage at this time, it will not affect the dispersion of the two fine feeds. At least the dispersion uniformity of the two feeds in the same area is relatively consistent or relatively stable. Because energy feed and protein feed are different from roughage, they mainly provide the energy and nutrition required for production and development of livestock. These are also the nutrients that are most difficult for livestock to obtain by themselves during daily grazing. It can better ensure that the ratio of these two types of special functional feeds in the feed eaten by livestock remains relatively stable.

[0022] In the actual processing of feed, such as Figure 1 , the premix is ​​discharged downward uniformly through a discharge bin 2, and the transmission chain plate 3 includes a plurality of transmission plates 301 hinged end to end in sequence, the transmission plate 301 is a solid plate with a smooth surface, which is easy for subsequent premixes to quickly fall from the transmission plate 301 falling into the mixing tower 1, and, during processing, before the first transmission plate 301 enters the mixing tower 1, a gate plate 8 in the mixing tower 1 that is linked to the transmission chain plate 3 seals the bottom of the mixing tower 1 to catch the falling materials later. The specific falling of the premix is ​​that at the moment when each transmission plate 301 enters the mixing tower 1, it will flip downward due to its own weight and be in a vertical state, and then the premix will fall from its surface, thereby realizing the premix being transported into the mixing tower 1 once.

[0023] Specifically in the actual scene, the stirring shaft 13 of this embodiment can move to the top of the mixing tower 1, and then move downward to enter the set height position of the mixing tower 1 to stir and mix the materials. Specifically, the bottom end of the stirring shaft 13 is conical, which is convenient for insertion into the material, and the spiral blades 14 arranged on the stirring shaft 13 can transport the materials in the mixing tower 1 axially downward as the stirring shaft 13 rotates. When the materials are transported to the gate plate 8, the materials are turned back due to the obstruction of the gate plate 8, that is, the materials are transported again through the gate plate 8. Figure 3 As shown, the gap channel between the spiral blade 14 and the inner wall of the mixing tower 1 is transported upward, thereby realizing a circulation flow in the vertical direction, so that the premix is ​​evenly dispersed in the crushed material.

[0024] Continue reading Figure 1 A chassis is provided on the right side of the mixing tower 1, and a large gear 4 is provided in the chassis. A driving wheel 5 is coaxially fixed to the large gear 4. The driving wheel 5 transmits a transmission belt 6 through a pair of driven wheels arranged symmetrically on the left and right. The transmission belt 6 can be arranged in an inverted triangle shape, and the horizontal section of the transmission belt 6 is located below a horizontally arranged support plate 10, as shown in FIG. Figure 1 and Figure 2 The support plate 10 is provided with a notch 12 along the length direction. The support plate 10 is used to support the transmission chain plate 3 so that it can slide horizontally. The bottom of the rear side plate 302 hinged to the last section of the transmission plate 301 of the transmission chain plate 3 is fixedly connected to the transmission belt 6 through the connecting column 11 passing through the notch 12, so that when the transmission belt 6 moves to the left, the transmission chain plate 3 moves to the left on the support plate 10 through the connecting column 11, and gradually falls into the mixing tower 1, that is, all the transmission plates 301 of the transmission chain plate 3 fall into the mixing tower 1 in turn, and the premix transmitted on each transmission plate 301 is discharged in turn, and the premix is ​​added one by one, and stirred and mixed one by one to improve the dispersion of the material.

[0025] At the same time, in this embodiment, if Figure 1 , its large gear 4 meshes with a small gear 7 below it to achieve reduction transmission, the purpose is that the gate plate 8 quickly seals the mixing tower 1, but the transmission chain plate 3 is gradually and steadily transmitted slowly, that is, the small gear 7 meshes with a horizontally sliding rack 9, the left end of the rack 9 is fixed with a horizontally set gate plate 8, and the end teeth 15 at both ends of the rack 9 are horizontally elastically slidably installed on the main body 18 of the rack 9. When the small gear 7 contacts the corresponding side of the end tooth 15, the gear meshing fails, so that the small gear 7 can rotate, but the rack 9 stops the existing linear movement. Specifically, if Figure 4 A slider 16 is fixed at the bottom end of the end teeth 15. The slider 16 is slidably mounted at one end of the slide groove on the main body 18 and is elastically connected to the other end of the slide groove through a pressure spring 17. The two pressure springs 17 are located between the two end teeth 15. In actual processing operation, the operator needs to start the motor to drive the large gear 4 to rotate counterclockwise, and the rack 9 moves to the left. In a short time, the gate plate 8 enters the mixing tower 1 and closes it. At this time, the large gear 4 is driven by the transmission belt 6 to move the transmission plate 301 toward the mixing tower 1. It has not yet completely entered the mixing tower 1. However, once the gate plate 8 is inserted into the mixing tower 1, the small gear 7 just meshes with one of the end teeth 15, for example, just with Figure 4The rightmost gear teeth are fully engaged, that is, the pinion 7 maintains continuous contact with the right side of the end tooth 15 at the right end. This is because the elastic telescopic mounting structure of the end tooth 15 makes the pinion 7 and the end tooth 15 in an elastic extrusion contact state, that is, the end tooth 15 is continuously in a position offset to the left, and the transmission fails. Therefore, the pinion 7 can continue to rotate so as not to affect the rotation of the large gear 4, that is, not to affect the transmission of the premix. When the last section of the transmission plate 301 falls into the mixing tower 1, the premix is ​​quantitatively filled within a relatively stable range within the set stage. After that, the drive motor reverses and the gate 8 quickly withdraws from the mixing tower 1, thereby realizing the unloading of the mixture. When the gear is engaged with the other end tooth 15, for example, with Figure 4 When the end teeth 15 on the left side are fully engaged, the gear transmission fails. Similarly, the pinion 7 can continue to rotate, so that the transmission chain plate 3 can leave the mixing tower 1 and reset to facilitate the next material transmission.

[0026] In more detail, after each transmission plate 301 falls into the mixing tower 1, the large gear 4 and the discharge bin 2 can be stopped to squeeze the upper layer of the ground feed to form a dense structure and a protective layer for easy storage and packaging. Figure 1 and Figure 5 As shown, a grinding extrusion disc 19 with grinding teeth 29 is designed to be pressed into the mixing tower 1. The grinding extrusion disc 19 can rotate and move downward under the drive of its transmission shaft, such as Figure 2A sliding block 20 is elastically and telescopically installed on the right side of the grinding disc. A right-angled trapezoidal wedge block 25 is provided on the upper surface of the sliding column 23 of the sliding block 20. The inclined surface of the wedge block 25 is used to contact the top wall of the inner sliding cavity 22 in a sliding bar 21, and controls the height position of the sliding bar 21. The top of the wedge block 25 is elastically and telescopically connected to the grinding extrusion disc 19 through a sliding rod 28. For example, the sliding column 23 is axially slidably inserted into the insertion hole in the grinding extrusion disc 19 and connected to the compression spring 24 in the insertion hole. When the sliding block 20 pops out of the side of the grinding and extrusion disk 19 and contacts the right side wall of the mixing tower 1, the material in the mixing tower 1 is fully squeezed, and the sliding bar 21 slides downward under the action of elasticity, and based on the contact between the wedge block 25 and the inner sliding cavity 22, the bottom surface of the sliding bar 21 is flush with the bottom surfaces of the grinding and extrusion disk 19 and the sliding block 20, and participates in forming the bottom end surface of the grinding and extrusion disk 19, and the bottom surfaces of the sliding bar 21 and the sliding block 20 are both provided with grinding teeth 29 for surface grinding and crushing. The sliding block 20 in the above embodiment is mainly used to avoid the above-mentioned transmission plate 301 that has been suspended, and when moving downward, it can be squeezed and contacted with the transmission plate 301, so as to scrape off the premix adhered thereon, so as to avoid the accumulation of too thick premix on the transmission plate 301 after repeated use, which affects the component amount of the mixed material. After moving downward to the area where the transmission plate 301 is suspended, the sliding block 20 will pop out, and then the grinding and extrusion disk 19 will fill the entire mixing tower 1, so as to achieve sufficient extrusion and grinding of the surface material, and form a layer of dense tissue at the end, which is conducive to storage in the packaging box.

[0027] More specifically, if Figure 5 The above-mentioned method of retracting and resetting the sliding block 20 is to provide an electromagnet 26 in the grinding and squeezing disc 19. The electromagnet 26 is used to attract the sliding bar 21 to move it upward. When the sliding bar 21 moves upward, the sliding block 20 quickly retreats into the grinding and squeezing disc 19 under the action of elasticity, and the bottom end of the sliding bar 21 is located on the storage step 27 between the grinding and squeezing disc 19 and the sliding block 20. Since the limiting effect of the sliding bar 21 is lost, the sliding block 20 can retreat into the grinding and squeezing disc 19 under the action of elasticity, and then it is conducive to vertical upward movement, passing through the overhanging area of ​​the transmission plate 301 in the mixing tower 1, avoiding being blocked by the transmission plate 301 and unable to move upward normally and exit the mixing tower 1. In practice, it is necessary for the electromagnet 26 to be energized immediately when the extrusion grinding disc moves upward to attract the sliding bar 21 or the sliding rod 28, so that the sliding block 20 can be timely retreated into the grinding and squeezing disc 19.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.

The flexible telescopic mounting structure makes the pinion (7) and the end teeth (15) in an elastic extrusion contact state, while the pinion (7) continues to rotate so as not to affect the rotation of the large gear (4); when the last transmission plate (301) falls into the mixing tower (1), the drive motor is reversed, the gate plate (8) withdraws from the mixing tower (1) to achieve unloading, and when the gear is meshed with the other end teeth (15), similarly, the pinion (7) can continue to rotate so that the transmission chain plate (3) leaves the mixing tower (1) and resets.

7. A method for producing mixed feed for animal husbandry according to claim 4, characterized in that: After each transmission plate (301) falls into the mixing tower (1), the large gear (4) and the discharge bin (2) stop working, and a grinding extrusion disc (19) with grinding teeth (29) is pressed into the mixing tower (1). A sliding block (20) is elastically and telescopically installed on the right side of the grinding disc. A right-angled trapezoidal wedge block (25) is provided on the upper surface of the sliding column (23) of the sliding block (20). The inclined surface of the wedge block (25) is used to contact the top wall of the inner sliding cavity (22) in a sliding bar (21). The top of the wedge block (25) The sliding bar (21) is elastically and telescopically connected to the grinding and extrusion disk (19) through a sliding rod (28). When the sliding block (20) pops out of the side of the grinding and extrusion disk (19) and contacts the right side wall of the mixing tower (1), the sliding bar (21) slides downward under the elastic action, and based on the contact between the wedge block (25) and the inner sliding cavity (22), the bottom surface of the sliding bar (21) is flush with the bottom surfaces of the grinding and extrusion disk (19) and the sliding block (20), and the bottom surfaces of the sliding bar (21) and the sliding block (20) are both provided with the grinding teeth (29).

8. A method for producing mixed feed for animal husbandry according to claim 7, characterized in that: The sliding block (20) is retracted and reset in the following manner: An electromagnet (26) is also provided in the grinding extrusion disc (19). The electromagnet (26) is used to attract the sliding bar (21) to move it upward. After the sliding bar (21) moves upward, the sliding block (20) retreats into the grinding extrusion disc (19) under the action of elasticity, and the bottom end of the sliding bar (21) is located on a storage step (27) between the grinding extrusion disc (19) and the sliding block (20). When the extrusion grinding disc moves upward, the electromagnet (26) is immediately energized so that the sliding block (20) retreats into the grinding extrusion disc (19).

9. A method for producing mixed feed for animal husbandry according to claim 8, characterized in that: The sliding column (23) is axially slidably inserted into the insertion hole in the grinding and extrusion disk (19) and is connected to the compression spring (24) in the insertion hole.
