DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Referring to the drawings in the description Figures 1-9 A rapeseed and crop straw feed mixing and conditioning device, comprising a stirring cylinder 1, a spiral stirring device 2 is installed at the bottom of the stirring cylinder 1, and the spiral stirring device 2 is used to stir and mix the feed inside the stirring cylinder 1; a retaining cylinder 3 is arranged inside the stirring cylinder 1, the retaining cylinder 3 is sleeved outside the spiral stirring device 2 and is fixedly connected with the stirring cylinder 1, and a discrete device 4 is arranged directly above the retaining cylinder 3; the discrete device 4 comprises a mounting frame 41, the mounting frame 41 is fixedly installed with the stirring cylinder 1, a rotating sleeve 42 is rotatably connected to the mounting frame 41, the rotating sleeve 42 is located directly above the retaining cylinder 3, a plurality of discrete blades 43 are fixedly connected to the bottom of the rotating sleeve 42, and the lower surfaces of the discrete blades 43 are attached to the upper surface of the retaining cylinder 3; a driving device 6 is installed on the mounting frame 41, and the driving device 6 is used to drive the rotating sleeve 42 to rotate.

[0029] In the above technical solution, a fixed rod is installed outside the retaining cylinder 3, and the retaining cylinder 3 is installed inside the stirring cylinder 1 through the fixed rod.

[0030] In this embodiment, as Figure 3 , Figures 5-9As shown, the rotating sleeve 42 is provided with a dispersion device 5, which comprises a rotating body 51 vertically slidingly installed in the interior of the rotating sleeve 42, a plurality of insertion rods 52 are fixedly installed in the circumferential direction of the rotating body 51, the lower ends of the insertion rods 52 extend to the interior of the holding cylinder 3, and a fixed tube 53 is fixedly connected to the upper end of the rotating body 51. The driving device 6 is further used for driving the rotating body 51, the insertion rods 52 and the fixed tube 53 to vertically move.

[0031] It should be noted that, as shown in Figure 9 , a fixed block can be arranged on the inner side of the rotating sleeve 42, and a sliding groove is arranged on the outer side of the rotating body 51. The fixed block cooperates with the sliding groove, so that the rotating body 51 can move vertically relative to the rotating sleeve 42. At the same time, when the rotating body 51 rotates, the rotating sleeve 42 can also be driven to rotate.

[0032] In this embodiment, as shown in Figure 6 and Figure 8 , the driving device 6 comprises a second speed reduction motor 61 fixedly installed on the mounting bracket 41, a movable sleeve 62 slidingly sleeved on the output shaft of the second speed reduction motor 61, the movable sleeve 62 being movably installed on the mounting bracket 41, a connecting arm 63 fixedly installed on the front end of the movable sleeve 62, a driving sleeve 64 rotatably connected to the fixed tube 53, a ball head rod 65 movably arranged on one end of the driving sleeve 64, and one end of the connecting arm 63 fixedly connected to one end of the ball head rod 65.

[0033] It should be noted that the movable sleeve 62 is horizontally inserted on the mounting bracket 41, so that the movable sleeve 62 can slide and rotate relative to the mounting bracket 41. The output shaft of the second speed reduction motor 61 and the movable sleeve can be connected by internal and external splines. When the second speed reduction motor 61 drives the movable sleeve 62 to rotate, the movable sleeve 62 drives the connecting arm 63 and the ball head rod 65 to rotate. The ball head part of the ball head rod 65 can roll in the groove on the driving sleeve 64. Therefore, when the ball head rod 65 rotates around the axis of the movable sleeve 62, the fixed tube 53 can be driven by the driving sleeve 64 to move up and down and rotate reciprocally. In the process of rotating the fixed tube 53, the ball head rod 65, the connecting arm 63 and the movable sleeve 62 are also pulled to move.

[0034] In this embodiment, as shown in Figure 3 and Figure 5 , the spiral stirring device 2 comprises a main shaft 21 rotatably connected to the inner bottom of the stirring cylinder 1, a plurality of spiral blades 23 fixedly connected to the outer side of the main shaft 21, a first speed reduction motor 22 arranged on the bottom of the stirring cylinder 1, and an output end of the first speed reduction motor 22 in transmission connection with the main shaft 21. The holding cylinder 3 is sleeved on the outer side of the spiral blade 23, and the holding cylinder 3 has a feeding space 30 between the bottom of the holding cylinder 3 and the bottom of the stirring cylinder 1.

[0035] It should be noted that when the main shaft 21 and the helical blade 23 are driven to rotate by the first speed reducer 22, the feed in the stirring cylinder 1 can be transported to the upper part of the holding cylinder 3, and then discharged from the upper end of the holding cylinder 3, so as to realize the purpose of mixing and preparing the feed.

[0036] In the embodiment, the specific implementation is that when the feed is mixed and prepared, the chopped rape and crop straw (such as corn straw) are first added into the stirring cylinder 1, and the leavening agent is then added, and then the mixing and preparation are performed by the helical stirring device 2. The main shaft 21 and the helical blade 23 are driven to rotate by the first speed reducer 22, the mixed feed is transported upward by the helical blade 23 from the position of the feeding space 30, and then discharged to the periphery from the upper end of the holding cylinder 3, so as to realize the purpose of mixing and preparing the feed. However, when the mixed feed has excessive moisture, the feed is difficult to be scattered by the helical blade 23 in the process of being transported upward by the helical blade 23, and the feed is formed into clumps. However, when the mixed feed is transported to the upper end of the holding cylinder 3, the rotating body 51, the inserting rod 52 and the fixed tube 53 are driven to reciprocate and rotate by the second speed reducer 61. When the rotating body 51 reciprocates, the rotating body 51 rotates together with the rotating sleeve 42 and the scattering blade 43. Since the mixed feed is continuously transported upward from the upper end of the holding cylinder 3, the mixed feed is scraped layer by layer to the outside by the scattering blade 43 in the process of reciprocating, and the mixed feed is thrown to the periphery by the centrifugal force. When the rotating body 51 reciprocates, the rotating sleeve 42 is not affected, and the inserting rod 52 is driven to reciprocate. In the process of reciprocating and rotating of the inserting rod 52, the inserting rod 52 can be inserted into the feed formed into clumps from top to bottom, and the feed is scattered, and the inserting rod 52 can be stirred when rotating around the axis of the rotating body 51, so as to realize the purpose of stirring the scattered feed.

[0037] The above technical scheme realizes the purpose of dispersing the feed formed into clumps by the rotating of the scattering blade 43, and the feed is scattered and stirred by the inserting rod 52, so that the feed and the leavening agent can be more quickly and uniformly mixed in the process of mixing and preparing the feed of the rape and the crop straw.

[0038] Referring to the drawings Figures 1-9 The mounting frame 41 is provided with the liquid injection device 7, the liquid injection device 7 comprises a liquid inlet pipe 72, the liquid inlet pipe 72 is fixedly installed on the mounting frame 41 and movably inserted into the upper end of the fixed tube 53, the mounting frame 41 is provided with a water pump 73, the water outlet of the water pump 73 is communicated with the upper end of the liquid inlet pipe 72, the inside of the fixed tube 53 is communicated with the upper end of the inserting rod 52 through a communication pipe 74, and the bottom end of the inserting rod 52 is provided with a hole.

[0039] Further, the liquid injection device 7 further comprises a plug rod 71, which is fixedly installed at the bottom of the inner side of the fixed tube 53, and the plug rod 71 can block the liquid inlet tube 72 when inserted into the liquid inlet tube 72.

[0040] It should be noted that the fermentation agent can be added to the mixed feed at the top of the holding cylinder 3 for mixing to make the mixing more sufficient and fast. Specifically, the fermentation agent is mixed with water to form a mixed solution, which is then pumped into the liquid inlet tube 72 by the water pump 73, and then enters the plug rod 52 from the communication tube 74, and finally is discharged from the hole at the bottom end of the plug rod 52 into the mixed feed. In this process, when the fixed tube 53 moves upward, the communication tube 74 is inserted into the liquid inlet tube 72, at this time, the liquid inlet tube 72 is closed, and the addition of the fermentation agent is stopped, and when the fixed tube 53 moves downward, the liquid inlet tube 72 is opened, and the addition of the fermentation agent continues, that is, the fermentation agent is not added when the plug rod 52 is pulled out of the mixed feed, and the fermentation agent is added when the plug rod 52 is inserted. It can avoid the problem of needing more time for uniform mixing caused by continuously adding too much fermentation agent to the mixed feed at the top layer of the holding cylinder 3 when the plug rod 52 is at the highest end.

[0041] Referring to the drawings attached to the specification Figures 4-9 The lower end of the mounting frame 41 is fixedly installed with a material blocking cover 8, the bottom of which is provided with an opening, and the bottom opening of the material blocking cover 8 is located at the lower position of the upper end of the holding cylinder 3, and the end of the discrete blade 43 is fixedly connected with a vertical scraper 431, which is arranged in abutment with the inner wall of the material blocking cover 8.

[0042] It should be noted that under the pushing of the discrete blade 43, the mixed feed flies out of the upper end of the holding cylinder 3, and if the feed directly flies out, it is easy to stick to the inner wall of the stirring cylinder 1 and cannot continue to participate in mixing. Therefore, the material blocking cover 8 is designed, which hits the inner wall of the material blocking cover 8 when the mixed feed flies out of the upper end of the holding cylinder 3, and then the vertical scraper 431 is driven by the reciprocating rotating discrete blade 43 to slide on the inner wall of the material blocking cover 8 to scrape it down to continue to participate in mixing.

[0043] Further, the bottom of the main shaft 21 is fixedly connected in the circumferential direction with a plurality of pushing blades 211, which are arranged in an arc shape and abut the bottom surface of the inner side of the stirring cylinder 1.

[0044] It should be noted that the pushing blades 211 rotate with the main shaft 21, and the pushing blades 211 can push the feed at the bottom of the stirring cylinder 1 to the bottom of the holding cylinder 3 to enable it to participate in mixing.

[0045] Referring to the drawings attached to the specification Figures 1-2The bottom of the stirring barrel 1 is provided with a discharge port 11, and the discharge port 11 is provided with a discharge device 9, the discharge device 9 comprises a discharge hopper 91, the discharge hopper 91 is arranged outside the discharge port 11 and is fixedly connected with the stirring barrel 1, the discharge port 11 is provided with a material plate 92, the upper end of the material plate 92 is hinged to the upper end of the discharge port 11, and the stirring barrel 1 is provided with a cylinder one 93, and the two ends of the cylinder one 93 are hinged to the stirring barrel 1 and the material plate 92 respectively.

[0046] It should be noted that the material plate 92 is used to block the discharge port 11, when the stirring is completed and the discharge is needed, the material plate 92 is driven to rotate upwards through the discharge port 11, the discharge port 11 is opened, and then the mixed and prepared feed is discharged from the discharge port 11.

[0047] Referring to the drawings Figures 1-2 The outside of the stirring barrel 1 is provided with a feeding device 100, the feeding device 100 comprises two swing rods 101, the upper ends of the two swing rods 101 are hinged to the stirring barrel 1, the lower ends of the two swing rods 101 are fixedly connected with a feeding hopper 102, at least one swing rod 101 is provided below with a cylinder two 103, and the two ends of the cylinder two 103 are hinged to the stirring barrel 1 and the swing rod 101 respectively.

[0048] It should be noted that in addition to manually adding rape and crop straws into the interior of the stirring barrel 1, the feeding device 100 can also be used for adding, the rape and the crop straws are manually added into the interior of the feeding hopper 102, then the cylinder two 103 pushes the swing rod 101 to swing upwards, the swing rod 101 drives the feeding hopper 102 to rotate to the upper end of the stirring barrel 1, so that the rape and the crop straws can be poured into the interior of the stirring barrel 1.

[0049] Finally, the above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
