Description

Technical Field

[0001] The invention belongs to the technical field of engineering construction, and in particular relates to a riprap pipe, a feeding height adjustment method and a feeding method. Background Art

[0002] A riprap is a device used to throw stones or other heavy objects to a designated location. It is widely used in underwater engineering, building construction and other engineering fields.

[0003] The riprap pipe is usually a cylindrical structure with a feeding port and a discharging port. The hopper feeds stones or other heavy objects into the riprap pipe from the feeding port, and the stones or other heavy objects inside the riprap pipe are thrown to the designated location from the discharging port.

[0004] In the prior art, the feeding port of the riprap pipe is usually set to multiple, and the multiple feeding ports are set on the peripheral wall of the riprap pipe along the height direction of the riprap pipe to meet different construction requirements. Although the feeding height of the riprap pipe can be adjusted to a certain extent by setting multiple feeding ports, the position of the feeding port is fixed, and the feeding height of the riprap pipe can only be adjusted to a limited extent. In addition, if the feeding height changes during the construction process, it is necessary to suspend the construction and reselect the feeding port. In addition, a baffle is usually provided at the feeding port. When the riprap pipe is feeding, the baffle at the feeding port is opened so that the feeding hopper is extended into the feeding port for feeding, but the hopper is prone to collision with the baffle. In some riprap pipes, the baffle is removed during feeding to prevent the hopper from colliding with the baffle. However, this undoubtedly adds additional work of disassembling and assembling the baffle, increases the complexity of construction, and reduces construction efficiency.

[0005] Therefore, it is of great significance to design a riprap pipe that is convenient for feeding or adjusting the feeding height. Summary of the invention

[0006] In view of the shortcomings existing in the related art, the present invention provides a riprap tube, a feeding height adjustment method and a feeding method. By extending the feeding port along the height direction of the riprap tube and providing a blocking member at the feeding port, not only the feeding height of the feeding port can be adjusted, but also the thrown material can be prevented from escaping from the inside of the riprap tube.

[0007] The present invention provides a riprap pipe, comprising:

[0008] The cylinder has a housing cavity defined inside, and the housing cavity is used to accommodate the thrown material; a discharge port is provided at the bottom of the cylinder, and the discharge port is connected with the housing cavity; a feeding port is provided on the peripheral wall of the cylinder, and the feeding port is connected with the housing cavity and extends along the height direction of the cylinder;

[0009] The blocking member is arranged at the feeding port and is used to partially block the feeding port; the lower end of the blocking member is connected to the cylinder, and the top of the blocking member slides between a first position and a second position along the height direction of the cylinder to adjust the feeding height of the feeding port.

[0010] The technical solution extends the feeding port along the height direction of the riprap tube and arranges a blocking member at the feeding port, and utilizes the top of the blocking member to move along the height direction of the riprap tube so that the feeding height of the feeding port can be adjusted, and at the same time, the part of the feeding port below the height of the feeding port is blocked by the blocking member; and the feeding member is arranged above the blocking member, which can not only avoid the blocking member and the feeding member from colliding with each other, but also drive the blocking member to move, so as to facilitate the adjustment of the feeding height.

[0011] In some of the embodiments, the riprap tube delivers the riprap material into the accommodating chamber through the feed member; the feed member is located above the blocking member to prevent the feed member and the blocking member from colliding with each other.

[0012] In some of the embodiments, the upper end of the blocking member is connected to a feeding member, and the feeding member applies a pulling force to the blocking member to make the blocking member slide between the first position and the second position.

[0013] The technical solution connects the upper end of the blocking member to the feeding member so that the feeding member applies a pulling force to the blocking member, thereby limiting the height of the top of the blocking member and further limiting the feeding height of the feeding port. The feeding member is located above the blocking member to prevent the feeding member from colliding with the blocking member during feeding.

[0014] In some embodiments, when the blocking member is in the first position, the size of the blocking member along the height direction of the cylinder is smaller than the size of the blocking member along the height direction of the cylinder when the blocking member is in the second position; when the blocking member is in the first position, the size of the feeding port along the height direction of the cylinder is larger than the size of the feeding port along the height direction of the cylinder when the blocking member is in the second position.

[0015] In some embodiments, the blocking member includes a plurality of baffles, which are arranged along the height direction of the cylinder, and adjacent baffles are hinged to each other; when the blocking member is in the first position, the baffles are folded to each other.

[0016] The technical solution designs the blocking member as a plurality of baffles hinged to each other so that the height of the blocking member can be adjusted, thereby enabling the feeding height of the riprap pipe to be adjusted.

[0017] In some of the embodiments, the cylinder is provided with a slideway, which is respectively arranged on the two side edges of the feeding port extending along the height direction of the cylinder; the baffle is provided with a connecting shaft, which is arranged corresponding to the slideway, and the connecting shaft is arranged in the slideway and slides along the slideway to guide the baffle to slide.

[0018] The technical solution provides a slideway on the cylinder body and a connecting shaft on the baffle, and utilizes the connecting shaft to slide along the slideway to guide the movement of the baffle.

[0019] In some of the embodiments, the baffle includes a first baffle and a second baffle, and the first baffle and the second baffle are arranged at intervals along the height direction of the cylinder; a connecting shaft is provided at the lower end of the first baffle; the first baffle and the second baffle adjacent to and located below it rotate around the connecting shaft as the axis, thereby realizing the folding of the first baffle and the second baffle.

[0020] In some of the embodiments, the slideway is provided with an insertion hole for the connecting shaft to be inserted, the connecting shaft is inserted into the insertion hole, and the connecting shaft is connected to the cylinder body by bolts.

[0021] In addition, the present invention also provides a method for adjusting the feeding height of the riprap tube, the adjustment method comprising the following steps:

[0022] The baffle of the blocking member below the height H1 is fixedly connected to the cylinder body by bolts, and the connecting bolts of the baffle of the blocking member above the height H1 and the cylinder body are removed;

[0023] Adjust the height of the feed piece to correspond to the feeding height H2 required by the feed port, so that the baffle plate above the height H1 moves to the corresponding position under the action of the baffle plate's own gravity and the pulling force of the feed piece, so as to adjust the height of the top of the baffle plate to meet the feeding height requirement of the feed port;

[0024] The blocking member includes at least one baffle plate above the height H1, and H1 and H2 satisfy the relationship: H1<H2.

[0025] In addition, the present invention also provides a feeding method for the riprap pipe, comprising the following steps:

[0026] Determine the required feed height for the riprap pipe;

[0027] Adjust the height of the feed piece to correspond to the required feeding height of the riprap pipe, so as to adjust the height of the top of the blocking piece to the required feeding height of the feed port;

[0028] The feeding piece conveys the thrown material into the containing cavity through the feeding port.

[0029] Based on the above technical scheme, the riprap tube in the embodiment of the present invention can not only adjust the feeding height of the feeding port, but also prevent the thrown material from escaping from the inside of the riprap tube; by extending the feeding port along the height direction of the riprap tube and providing a blocking member at the feeding port, the top of the blocking member can be moved along the height direction of the riprap tube, so that the feeding height of the feeding port can be adjusted, and at the same time, the part of the feeding port below the height of the feeding port is blocked by the blocking member; and the feeding member is provided above the blocking member, which can not only avoid the blocking member and the feeding member from colliding with each other, but also drive the blocking member to move, so as to facilitate the adjustment of the feeding height.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] As attached Figure 1 , Figure 3 and Figure 4 As shown, in an exemplary embodiment of the riprap tube of the present invention, the riprap tube includes a cylinder 100 and a blocking member; a receiving chamber 102 is defined inside the cylinder 100, and the receiving chamber 102 is used to receive stones or heavy objects to be thrown; the receiving chamber 102 extends along the height direction of the cylinder 100; a discharge port is provided on the cylinder 100, and the discharge port is arranged at the bottom of the cylinder 100, and the discharge port is communicated with the receiving chamber 102, and the stones or heavy objects in the receiving chamber 102 are thrown to a designated position through the discharge port; a feeding port 101 is provided on the peripheral wall of the cylinder 100, and the feeding port 101 is connected to the receiving chamber 102. The accommodating chamber 102 is connected, and the feeding port 101 extends along the height direction of the cylinder 100, and stones or heavy objects enter the accommodating chamber 102 from the feeding port 101; a blocking member is provided at the feeding port 101, and is used to block the feeding port 101 to prevent stones or heavy objects in the accommodating chamber 102 from leaving the accommodating chamber 102 from the feeding port 101; the lower end of the blocking member is connected to the cylinder 100, and the top of the blocking member is used to limit the feeding height of the feeding port 101; the top of the blocking member can slide between a first position and a second position, and the first position and the second position are set along the height direction of the cylinder 100.

[0052] It should be noted that when the top of the blocking member slides between the first position and the second position, the size of the blocking member along the height direction of the cylinder 100 changes, the opening size of the feeding port 101 along the height direction of the cylinder 100 also changes, and the feeding height of the feeding port 101 also changes.

[0053] like Figure 5 As shown, the material transport mechanism transports stones or heavy objects to the vicinity of the riprap pipe, and the feed member 300 is used to transport the stones or heavy objects from the feed port 101 to the accommodating chamber 102 .

[0054] In some embodiments, the feed member 300 is provided with a hopper, which extends into the feeding port 101 to feed stones or heavy objects into the accommodating chamber 102 .

[0055] In some embodiments, the feeding port 101 is disposed through the barrel 100 along the height direction of the barrel 100 so that the feeding height of the feeding port 101 has a larger range.

[0056] It should be noted that the feeding port 101 includes two parts, one part is located above the feeding height, which is the required feeding port 101, and the feed member 300 delivers the thrown material into the accommodating chamber 102 through this part of the feeding port 101; the other part is located below the feeding height, and this part of the feeding port 101 needs to be blocked by a blocking member to prevent stones or heavy objects in the accommodating chamber 102 from leaving the accommodating chamber 102 through this part of the feeding port 101. In actual applications, the feeding height is variable, so the dimensions of the two parts of the feeding port 101 along the height direction of the cylinder 100 are also variable.

[0057] The above-mentioned riprap pipe is designed to have a blocking member that can be extended and retracted along the height direction of the cylinder 100, so that the height dimension of the blocking member along the height direction of the cylinder 100 can be adjusted according to the feeding height.

[0058] In some embodiments, the height of the top of the blocking member is the feeding height of the feeding port 101 .

[0059] In the above-mentioned riprap tube, the blocking member is located below the feed member 300, and the feed member 300 is located above the blocking member to prevent the feed member 300 from colliding with the blocking member during feeding, thereby preventing the feed member 300 or the riprap tube from being damaged, and ensuring the reliability of the riprap tube feeding.

[0060] The feed piece 300 is driven by a mechanical device, and the height of the feed piece 300 is also adjusted by a mechanical device. By connecting the upper end of the blocking piece to the feed piece 300, the feed piece 300 can apply a pulling force to the blocking piece, so that the feed piece 300 drives the top of the blocking piece to slide between the first position and the second position. By connecting the blocking piece to the feed piece 300, the feed piece 300 drives the top of the blocking piece to slide, and by adjusting the height of the feed piece 300, the height of the top of the blocking piece can be adjusted, thereby adjusting the feeding height of the feeding port 101.

[0061] It should be noted that the height of the feed piece 300 corresponds to the feed height of the feed port 101. In some embodiments, the height of the feed piece 300 is the feed height of the feed port 101. In other embodiments, the height of the feed piece 300 is higher than the feed height of the feed port 101.

[0062] Since the sliding of the top of the blocking member is driven by the pulling force of the feed member 300, the height of the top of the blocking member changes according to the height of the feed member 300. Therefore, during construction, if the feeding height of the riprap pipe changes, the feeding height of the riprap pipe can be adjusted by adjusting the height of the feed member 300.

[0063] It should also be noted that when the blocking member is in the first position, the feed member 300 does not apply a pulling force to the blocking member, the blocking member falls under the action of its own gravity, and the blocking member is bent and folded, thereby reducing the size of the blocking member along the height direction of the cylinder 100; when the blocking member is in the second position and any position between the first position and the second position, the feed member 300 applies a pulling force to the blocking member to prevent the blocking member from falling to the first position.

[0064] It should be noted that if Figure 4 and Figure 6 As shown, the height of the second position is higher than that of the first position, and the dimension of the blocking member along the height direction of the cylinder 100 when the blocking member is in the second position is greater than the dimension of the blocking member along the height direction of the cylinder 100 when the blocking member is in the first position.

[0065] In this embodiment, when the blocking member is in the first position, the size of the blocking member along the height direction of the cylinder 100 is the smallest, and the size of the feeding port 101 along the height direction of the cylinder 100 is the largest; when the blocking member is in the second position, the size of the blocking member along the height direction of the cylinder 100 is the largest, and the size of the feeding port 101 along the height direction of the cylinder 100 is the smallest.

[0066] In the above-mentioned riprap pipe, the feeding port 101 is extended along the height direction of the cylinder 100 so that the size of the feeding port 101 along the height direction of the cylinder 100 is larger, and a blocking member is provided at the feeding port 101. The blocking member is used to block the feeding port 101 to prevent stones or heavy objects in the accommodating chamber 102 from leaving the accommodating chamber 102 from the feeding port 101, and the top of the blocking member can limit the feeding height of the feeding port 101. By adjusting the height of the top of the blocking member, the feeding height of the feeding port 101 can be adjusted.

[0067] The blocking member includes a plurality of baffles 200, which are arranged along the height direction of the cylinder 100, and adjacent baffles 200 are hinged to each other so that the blocking member can be folded, so that the height of the blocking member can be adjusted, and further the feeding height of the riprap pipe can be adjusted.

[0068] It should be noted that if Figure 7 and Figure 8 As shown, when the height of the blocking member is less than the sum of the heights of the plurality of baffles 200, the blocking member is folded and the baffles 200 are rotated to reduce the size of the baffles 200 along the height direction of the cylinder 100, thereby reducing the height of the blocking member.

[0069] like Figure 2 As shown, the cylinder 100 is provided with a slideway 103, and the slideway 103 is respectively arranged on the two side edges of the feeding port 101 extending along the height direction of the cylinder 100; Figure 8 As shown, the baffle 200 is provided with a connecting shaft 211 , and the connecting shaft 211 is arranged corresponding to the slideway 103 . The connecting shaft 211 is arranged in the slideway 103 and slides along the slideway 103 to guide the baffle 200 to slide.

[0070] It should be noted that the slideway 103 can also constrain the baffle 200 through the connecting shaft 211 to increase the reliability of the baffles 200 being folded together.

[0071] like Figure 9-11As shown, the baffle 200 includes a first baffle 210 and a second baffle 220, and the first baffle 210 and the second baffle 220 are arranged at intervals along the height direction of the cylinder 100; wherein a connecting shaft 211 is provided at the lower end of the first baffle 210, and the first baffle 210 and the second baffle 220 adjacent to and located below the first baffle 210 rotate around the connecting shaft 211 as the axis, thereby realizing the folding of the first baffle 210 and the second baffle 220.

[0072] like Figure 6 As shown, when the blocking member is in the first position, the connection between the first baffle plate 210 and the second baffle plate 220 protrudes toward the outside of the barrel 100, so that the blocking member is folded. When the blocking member is folded, the connection between the first baffle plate 210 and the second baffle plate 220 is designed to protrude toward the outside of the accommodating cavity 102, which can prevent the blocking member from occupying the internal space of the accommodating cavity 102 when folded, and can prevent stones or heavy objects from damaging the protruding part of the blocking member.

[0073] In some embodiments, when the blocking member is not folded, the connection between the two baffles 200 in the same group also protrudes toward the outside of the cylinder 100 to limit the rotation angle of the baffle 200, thereby ensuring the reliability of the rotation and folding of the baffle 200.

[0074] It should be noted that when the top of the blocking member slides along the height of the cylinder 100 so that the top of the blocking member meets the feeding requirements of the riprap pipe, in theory, the entire blocking member is folded, that is, all baffles 200 of the blocking member are usually rotated at the same angle to fold the blocking member.

[0075] In practical applications, the height of the riprap tube is relatively large, and the number of baffles 200 is also relatively large. If the feeding height of the riprap tube is relatively small, the rotation angle of the baffle 200 will be relatively large, which will not only easily lead to unstable movement of the baffle 200, but also increase the pulling force of the feeding member 300 on the blocking member. Therefore, the above-mentioned riprap tube designs the blocking member to be partially foldable or completely foldable to increase the reliability of the blocking member.

[0076] like Figure 2 As shown, the slideway 103 is provided with an insertion hole 104 for inserting the connecting shaft 211. The connecting shaft 211 is inserted into the insertion hole 104 to connect the first baffle 210 to the cylinder 100, thereby preventing the first baffle 210 from sliding relative to the cylinder 100 along the height direction of the cylinder 100.

[0077] The connecting shaft 211 is provided with a first connecting hole 212, and the wall of the slideway 103 is provided with a second connecting hole 105. The second connecting hole 105 is arranged corresponding to the first connecting hole 212. Bolts are arranged in the first connecting hole 212 and the second connecting hole 105 at the same time, so that the first baffle 210 is connected to the cylinder 100 by bolts.

[0078] It should be noted that if two adjacent connecting shafts 211 along the height direction of the cylinder 100 are connected to the cylinder 100 by bolts, the baffle 200 located between the two connecting shafts 211 cannot be folded.

[0079] It should also be noted that if the connecting shaft 211 is connected to the cylinder 100 by bolts, the first baffle 210 provided with the connecting shaft 211 cannot rotate, and accordingly, the second baffle 220 connected to the first baffle 210 cannot rotate either.

[0080] When the feeding height of the riprap tube is high, the baffle 200 located at the lower part of the blocking member is connected to the cylinder 100 by bolts, so that the baffle 200 located at the upper part of the blocking member can slide relative to the cylinder 100, so that only the upper part of the baffle 200 is folded to adjust the feeding height of the riprap tube. This design can not only increase the reliability of the movement of the baffle 200, reduce the pulling force of the feeding member 300 on the blocking member, but also increase the stability and reliability of feeding.

[0081] When the feeding height of the riprap pipe is low, the blocking member is folded as a whole so that the top of the blocking member meets the requirement of the feeding height.

[0082] It should be noted that the minimum height of the blocking member after the entire blocking member is folded is smaller than the minimum height of the blocking member after a portion of the blocking member is folded.

[0083] In the above-mentioned riprap tube, the blocking member can be partially folded or completely folded, so that the blocking member can be better adjusted in height, and whether the blocking member is completely folded or partially folded is selected according to the feeding height of the riprap tube.

[0084] Based on the above-mentioned riprap pipe, the present invention also provides a feeding height adjustment method, which is used to adjust the feeding height of the above-mentioned riprap pipe. The adjustment method comprises the following steps:

[0085] Determine the required feeding height H2 of the riprap pipe according to the actual construction requirements;

[0086] According to the required feeding height H2 of the riprap tube, the blocking member is selected to be partially folded or completely folded;

[0087] The height of the feeding member is adjusted to correspond to the required height H2 of the feeding port 101, so that the height of the top of the blocking member meets the requirement of the feeding height H2.

[0088] In this embodiment, the height of the top of the blocking member is taken as the feeding height of the feeding port 101 as an example to introduce the above-mentioned method for adjusting the feeding height of the riprap tube in detail. The adjustment method includes the following steps:

[0089] Determine the required feeding height H2 of the riprap pipe according to the actual construction requirements;

[0090] When the feeding height H2 is greater than or equal to the first set value, the blocking member is partially folded; the baffle 200 of the blocking member below the height H1 is fixedly connected to the cylinder 100 by bolts, and the connecting bolts between the baffle 200 of the blocking member above the height H1 and the cylinder 100 are removed, so that the baffle 200 located above the height H1 can slide relative to the cylinder 100 along the slideway 103;

[0091] The height of the feed piece is adjusted to correspond to the required height H2 of the feed port 101, so that the baffle 200 above the height H1 moves to the corresponding position under the combined action of the pulling force of the feed piece and the weight of the baffle 200 itself, so that the top height of the baffle 200 located at the uppermost end of the baffle is the required feeding height H2 of the riprap pipe;

[0092] When the feeding height H2 is less than the first set value, the blocking member is folded as a whole, and the connecting bolts of all the baffles 200 and the cylinder 100 are removed, so that all the baffles 200 can slide relative to the cylinder 100; the height of the feeding member is adjusted to correspond to the required height H2 of the feeding port 101, so that all the baffles 200 can move to the required position under the combined action of their own gravity and the pulling force of the feeding member, so that the top height of the baffle 200 located at the uppermost end of the blocking member is the feeding height H2 required by the riprap pipe.

[0093] The blocking member includes at least one baffle plate 200 above the height H1, and H1 and H2 satisfy the relationship: H1<H2.

[0094] It should be noted that the minimum height of the part of the baffle 200 located above the height H1 after folding is H3, and H1, H2 and H3 satisfy the relationship: H2≥H1+H3.

[0095] It should also be noted that the first set value is determined based on the number of baffles 200, the height of the baffles 200, and the height of the same group of baffles 200 after folding, which will not be repeated here.

[0096] In the above-mentioned feeding height adjustment method, by selecting the folding mode of the blocking member according to the feeding height of the riprap tube, when the feeding height of the riprap tube is high, the blocking member is partially folded, so that the baffle 200 located below the height H1 is fixedly connected to the cylinder 100 by bolts, so that this part of the baffle 200 blocks the feeding port 101 below the height H1 to prevent stones or heavy objects in the accommodating chamber 102 from leaving the accommodating chamber 102 from the feeding port 101; the baffle 200 located above the height H1 can slide relative to the cylinder 100 along the slide 103 to adjust the feeding height of the feeding port 101; when the feeding height of the riprap tube is low, the blocking member is folded as a whole, so that all the baffles 200 rotate under the combined action of their own gravity and the pulling force of the feeding member.

[0097] The feeding height adjustment method of the riprap pipe adjusts the feeding height of the riprap pipe by adjusting the height of the feed piece, and during the construction process, the feeding height of the riprap pipe can be adjusted at any time according to actual construction needs.

[0098] Based on the above-mentioned riprap pipe, the present invention also provides a feeding method, comprising the following steps:

[0099] Determine the required feeding height of the riprap pipe according to the actual construction requirements;

[0100] Adjust the height of the feed piece to correspond to the required feeding height of the riprap pipe, so that the top of the blocking piece meets the feeding height requirement of the feed port 101;

[0101] The feeding member delivers the thrown material into the accommodating chamber 102 through the feeding port 101 .

[0102] The feeding method of the riprap pipe is described in detail below by taking the height of the top of the blocking member as the feeding height of the feeding port 101 as an example.

[0103] The above-mentioned feeding method comprises the following steps:

[0104] According to the actual construction requirements, determine the required feeding height H2 of the riprap pipe.

[0105] When the feeding height H2 is greater than or equal to the first set value, the blocking member is partially folded; the baffle 200 of the blocking member below the height H1 is fixedly connected to the cylinder 100 by bolts, and the connecting bolts between the baffle 200 of the blocking member above the height H1 and the cylinder 100 are removed, so that the baffle 200 located above the height H1 can slide relative to the cylinder 100 along the slideway 103;

[0106] The height of the feed piece is adjusted to correspond to the required height H2 of the feed port 101, so that the baffle 200 above the height H1 moves to the corresponding position under the combined action of the pulling force of the feed piece and the weight of the baffle 200 itself, so that the top height of the baffle 200 located at the uppermost end of the baffle is the required feeding height H2 of the riprap pipe;

[0107] When the feeding height H2 is less than the first set value, the blocking member is folded as a whole, and the connecting bolts of all the baffles 200 and the cylinder 100 are removed, so that all the baffles 200 can slide relative to the cylinder 100; the height of the feeding member is adjusted to correspond to the required height H2 of the feeding port 101, so that all the baffles 200 can move to the required position under the combined action of their own gravity and the pulling force of the feeding member, so that the top height of the baffle 200 located at the uppermost end of the blocking member is the feeding height H2 required by the riprap pipe.

[0108] The feeding member delivers the thrown material into the accommodating chamber 102 through the feeding port 101 .

[0109] The feeding method of the riprap tube is simple and easy to operate, and there is no need to manually adjust the feeding height. The feeding height adjustment method is simple and has high precision.

[0110] The riprap tube extends the feeding port 101 along the height direction of the riprap tube, and the size of the blocking member can be adjusted along the height direction of the riprap tube, so that the top of the blocking member limits the feeding height of the feeding port 101, thereby making the feeding height of the riprap tube adjustable; and the feeding member 300 is arranged above the blocking member, which can not only avoid the blocking member and the feeding member 300 from colliding with each other, but also drive the blocking member to move, thereby facilitating the adjustment of the feeding height.

[0111] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0112] 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, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
