Description

Technical Field

[0001] The invention relates to the technical field of edible fungus production equipment, and in particular to a raw material premixing device for cultivating edible fungus strains. Background Art

[0002] At present, the main raw materials used in the production of edible fungi in my country include wastes from crops and forestry production, such as various wood-rotting fungi suitable for cultivating oyster mushrooms, shiitake mushrooms, and grass-rotting fungi suitable for cultivating Agaricus bisporus. In addition, artificial cultivation of edible fungi also requires the addition of some sucrose, lime, gypsum, potassium dihydrogen phosphate and other substances to meet the requirements of edible fungi for nutrition or environmental conditions. Therefore, edible fungi need to mix the cultivation raw materials of multiple components in advance to make a culture medium during its production process. The raw material mixing equipment used in the current cultivation of edible fungi strains is an ordinary mixer, which mixes the materials through multiple groups of stirring blades arranged in the mixing drum. Since there are many raw materials used in the cultivation of edible fungi, and the density difference is large, during the mixing process, materials with high density, such as cow and horse manure, will gradually move down to the bottom layer of the material, while materials with low density, such as straw and wheat straw, will gather at the top of the material, resulting in poor mixing effect, which is not conducive to the subsequent cultivation of edible fungi strains.

[0003] Chinese patent CN220823773U discloses a raw material premixing device for edible fungus strain cultivation, including a mixing box and a base frame, the mixing box is fixedly connected to the top of the base frame, the middle part of the mixing box is rotatably provided with an outer cylinder extending to the bottom of the mixing box, the inner part of the outer cylinder is rotatably provided with a core rod coaxial with its axis, and a motor is provided on the lower side of the mixing box; the output end of the motor is fixedly connected with a driving gear. This patent crushes the material by the reverse rotation of the upper and lower groups of stirring blades, and drives the mixing box to turn up and down by a wavy lifting ring, thereby improving the uniformity of material mixing. Although the above scheme can play a certain role in the mixing of materials, when the material is turned over by vibration, the turning amplitude of the material close to the vibration source is larger, while the turning amplitude of the side away from the vibration source is lower, which will increase the time for mixing the material, thereby affecting the overall efficiency of edible fungus strain cultivation. Summary of the invention

[0004] In view of the above problems, a raw material premixing device for cultivating edible fungus strains is provided.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figures 1 to 7 As shown: a raw material premixing device for cultivating edible fungi strains, comprising a frame 1 and a mixing drum 2 arranged on the frame 1, the mixing drum 2 comprising an upper drum 21 and a lower drum 22 coaxially sleeved together, the upper drum 21 and the lower drum 22 relatively expand and contract in the axial direction to change the volume inside the mixing drum 2; a mixing shaft 221 is coaxially rotatably arranged on the lower drum 22, one end of the mixing shaft 221 passes through a through hole opened on the top of the upper drum 21 and extends out of the upper drum 21; a vertical axis is arranged on the frame 1 The main shaft 11 is in a state and can rotate, and the axis of the mixing drum 2 is obliquely installed on the main shaft 11; a rotating joint 2211 rotatably connected to the mixing shaft 221 and a telescopic control device 12 are arranged above the mixing drum 2, which drives the rotating joint 2211 to move along the axial direction of the mixing shaft 221 and then drives the mixing shaft 221 to expand and contract relative to the upper cylinder 21, thereby changing the volume of the mixing drum 2; a rotation control device 13 is arranged on the frame 1 to control the main shaft 11 and the mixing shaft 221 to rotate around their respective axes.

[0035] The upper cylinder 21 and the lower cylinder 22 of the mixing drum 2 are respectively provided with a feed port 213 and a discharge port 222. First, various materials are put into the mixing drum 2 from the feed port 213. At this time, the main shaft 11 and the mixing shaft 221 are controlled by the rotation control device 13, so that the main shaft 11 and the mixing shaft 221 rotate around their respective axes. The materials in the mixing drum 2 are stirred by the rotation of the mixing shaft 221, thereby improving the mixing of various materials. The rotation of the main shaft 11 drives the mixing drum 2 connected thereto, so that the axis of the mixing drum 2 rotates around the main shaft 11 in an inclined state. The axis of the mixing drum 2 is set to be inclined, so that the materials can be better turned over inside the mixing drum 2, which promotes the mixing of the materials. It contacts the stirring shaft 221, thereby improving the mixing of various materials. At the same time, the telescopic control device 12 drives the rotary joint 2211 to move along the axis of the stirring shaft 221. The rotary joint 2211 drives the stirring shaft 221 to slide along its axis while rotating. The movement of the stirring shaft 221 also drives the movement of the lower cylinder 22, so that the lower cylinder 22 can slide along the axis of the upper cylinder 21, thereby changing the volume in the stirring drum 2. The movement of the lower cylinder 22 makes the material in the stirring drum 2 be thrown up, and the rotation of the main shaft 11 and the stirring shaft 221 can realize the multi-directional movement of the material, thereby further promoting the mixing of various materials and improving the uniformity of material mixing.

[0036] like Figures 1 to 8As shown: the rotation control device 13 includes a mounting frame 131, a connecting shaft 1311, a conical gear ring 1312 and a first bevel gear 2111. A sleeve 211 which is coaxial with its axis and can rotate is provided inside the upper cylinder 21. The first bevel gear 2111 is sleeved on the sleeve 211. The mounting frame 131 is fixedly connected to the frame 1. The connecting shaft 1311 is sleeved on the main shaft 11 and fixedly connected to the mounting frame 131. The conical gear ring 1312 is fixedly connected to the bottom of the connecting shaft 1311, and the conical gear ring 1312 is meshedly connected to the first bevel gear 2111.

[0037] The stirring shaft 221 of the lower cylinder 22 will pass through the sleeve 211 and slide with it. The part where the stirring shaft 221 is connected to the sleeve 211 is a hexagonal prism structure. The rotation of the main shaft 11 will drive the axis of the stirring drum 2 to rotate around the main shaft 11. At this time, the sleeve 211 located on the upper cylinder 21 will rotate around the main shaft 11, thereby driving the rotation of the first bevel gear 2111, so that the first bevel gear 2111 can rotate around the circumference of the conical gear ring 1312. Since the two are meshed and connected, and the conical gear ring 1312 is in a fixed state, When the first bevel gear 2111 rotates around the axis of the conical gear ring 1312, the two will generate self-rotation through the meshing of the two. The rotation of the first bevel gear 2111 drives the rotation of the sleeve 211 connected thereto, and the rotation of the sleeve 211 drives the rotation of the stirring shaft 221. The rotation of the stirring shaft 221 drives the material in the mixing drum 2 to be fully mixed, thereby improving the uniformity of material mixing. The setting of the fixed frame and the connecting shaft 1311 is used to fix the conical gear ring 1312 and provide a platform for supporting the conical gear ring 1312.

[0038] like Figures 1 to 8 As shown: the rotation control device 13 also includes a drive shaft 132, a first rotation drive motor 134 and a first synchronous belt 133. The drive shaft 132 is rotatably arranged on the frame 1 in a vertical state. The first synchronous belt 133 is sleeved on the top of the main shaft 11 and the drive shaft 132. The first rotation drive motor 134 is fixedly connected to the frame 1, and the drive shaft 132 is transmission-connected to the output shaft of the first rotation drive motor 134.

[0039] By starting the first rotary drive motor 134, the output shaft of the first rotary drive motor 134 drives the rotation of the drive shaft 132 connected thereto, and the rotation of the drive shaft 132 drives the rotation of the first synchronous belt 133, and the rotation of the first synchronous belt 133 drives the rotation of the main shaft 11, and the rotation of the main shaft 11 drives the rotation of the mixing drum 2 connected thereto, so that the inclined axis of the mixing drum 2 rotates around the axis of the main shaft 11, and at the same time, the rotation of the mixing drum 2 drives the rotation of the sleeve 211 and the first bevel gear 2111, so that when the first bevel gear 2111 rotates around the main shaft 11, it can generate rotation through the meshing connection with the conical gear ring 1312, thereby the main shaft 11 and the mixing shaft 221 can be controlled to rotate around their respective axes through the rotation control device 13, so that there is no need to equip the mixing shaft 221 of the mixing drum 2 and the main shaft 11 with independent driving sources respectively, and a single driving source can drive both to rotate at the same time, thereby reducing the cost of the equipment and the manufacturing cost of the equipment.

[0040] like Figures 1 to 8 As shown: the telescopic control device 12 includes a rotating frame 121 with an annular structure, a second synchronous belt 1211 and a driving assembly 122 for driving the rotary joint 2211 to move. The rotating frame 121 can rotate around the main shaft 11 and is arranged on the top of the frame 1. The second synchronous belt 1211 is sleeved on the driving shaft 132 and the rotating frame 121, and the driving assembly 122 is fixedly connected to the rotating frame 121.

[0041] The first rotary drive motor 134 drives the driving shaft 132 to rotate. The rotation of the driving shaft 132 drives the first synchronous belt 133 and the second synchronous belt 1211. The rotation of the second synchronous belt 1211 drives the rotating frame 121. The rotation of the rotating frame 121 drives the driving assembly 122. The driving assembly 122 drives the rotary joint 2211 to move, so that the stirring shaft 221 can move along its axial direction, thereby driving the lower cylinder 22 and the upper cylinder 21 to slide relative to each other, thereby changing the volume in the stirring drum 2. The movement of the lower cylinder 22 causes the material to be thrown up in the stirring drum 2. In conjunction with the rotation of the main shaft 11 and the stirring shaft 221, the multi-directional movement of the material can be achieved, thereby further promoting the mixing of multiple materials and improving the uniformity of material mixing.

[0042] like Figures 1 to 6 and Fig.11 As shown: the driving assembly 122 includes a rotating disk 1221 with a horizontal axis, a fixed shaft 12211 is provided at the edge of the rotating disk 1221, the axis of the fixed shaft 12211 is parallel to the axis of the rotating disk 1221, a connecting rod 12212 is provided between the rotating disk 1221 and the rotating joint 2211, and both ends of the connecting rod 12212 are respectively hinged to the fixed shaft 12211 and the rotating joint 2211.

[0043] The rotation of the rotating disk 1221 drives the rotation of the fixed shaft 12211, so that the fixed shaft 12211 rotates around the axis of the rotating disk 1221, and the rotation of the fixed shaft 12211 drives the movement of the connecting rod 12212 hinged thereto, and the movement of the connecting rod 12212 drives the movement of the rotating joint 2211. Since the stirring shaft 221 can only slide along its axial direction, the rotating joint 2211 drives the stirring shaft 221 to move, and then drives the lower cylinder 22 and the upper cylinder 21 to slide relative to each other, thereby changing the volume in the stirring drum 2, and the movement of the lower cylinder 22 causes the material to be thrown up in the stirring drum 2, and the rotation of the main shaft 11 and the stirring shaft 221 can realize the multi-directional movement of the material, thereby further promoting the mixing of multiple materials and improving the uniformity of material mixing. The driving of the rotating disk 1221 is preferably driven by a servo motor.

[0044] like Figures 1 to 6 and Fig.11 As shown: the driving assembly 122 also includes a support shaft 1222 for driving the rotating disk 1221 to rotate, a second bevel gear 12221 sleeved on the support shaft 1222, a transmission shaft 1223 located beside the support shaft 1222, a third bevel gear 12231 and a first gear 12232 sleeved on both ends of the support shaft 1222, and a first ring gear 1224 fixedly connected to the frame 1 and coaxial with the rotating frame 121, the third bevel gear 12231 is meshedly connected with the second bevel gear 12221, and the first gear 12232 is meshedly connected with the first ring gear 1224.

[0045] When the rotating frame 121 rotates, the transmission shaft 1223 is driven to rotate, so that the transmission shaft 1223 rotates around the axis of the main shaft 11, and the rotation of the transmission shaft 1223 drives the first gear 12232 to rotate. Since the first gear 12232 is meshed and connected with the first ring gear 1224, and the first ring gear 1224 is coaxial with the rotating frame 121, the first gear 12232 rotates along the first ring gear 1224 when it rotates around the main shaft 11. At the same time, the first gear 12232 rotates on its own, and the rotation of the first gear 12232 drives the transmission shaft 1223 to rotate. The rotation of the transmission shaft 1223 drives the third bevel gear 12231 at the other end thereof to rotate, and the rotation of the third bevel gear 12231 drives the The rotation of the second bevel gear 12221 which is meshed with it drives the rotation of the supporting shaft 1222 connected thereto through the rotation of the second bevel gear 12221, and the rotation of the rotating disk 1221 is driven by the rotation of the supporting shaft 1222, and the movement of the connecting rod 12212 is driven by the fixed shaft 12211 of the rotating disk 1221, and the movement of the rotary joint 2211 and the stirring shaft 221 is driven by the connecting rod 12212, thereby achieving relative sliding between the cylinder and the upper cylinder 21, thereby changing the volume in the stirring cylinder 2, and the movement of the lower cylinder 22 makes the material be thrown up in the stirring cylinder 2, and the rotation of the main shaft 11 and the stirring shaft 221 can realize the multi-directional movement of the material, thereby further promoting the mixing of multiple materials and improving the uniformity of material mixing.

[0046] like Figures 1 to 3 and Figures 6 to 9 As shown: a funnel-shaped partition 212 is provided inside the upper cylinder 21, and the mixing cylinder 2 is divided into a pre-mixing chamber 2121 and a mixing chamber 2122 by the partition 212. A discharge port 2123 for connecting the pre-mixing chamber 2121 and the mixing chamber 2122 is provided in the center of the partition 212, and a mixing frame 2124 capable of crushing materials is provided in the pre-mixing chamber 2121.

[0047] By setting the partition 212, the mixing drum 2 can be divided into a pre-mixing chamber 2121 and a mixing chamber 2122, so that the material entering the mixing drum 2 from the feed port 213 will first enter the pre-mixing chamber 2121, and the material will be crushed by the stirring frame 2124 in the pre-mixing chamber 2121. After crushing, the material can enter the mixing chamber 2122 from the discharge port 2123, and the material is turned over by the lower cylinder 22, and the material is mixed by the stirring shaft 221, so as to further promote the mixing of various materials and improve the uniformity of material mixing. By setting the pre-mixing chamber 2121, the material can be made finer and the pressure of the mixing drum 2 when mixing various materials is reduced.

[0048] like Figures 1 to 3 and Figures 6 to 9As shown: a plug body 2212, a mounting plate 2214 and a first elastic member 2213 are provided in the middle part of the stirring shaft 221, the plug body 2212 is sleeved on the stirring shaft 221 and slidably cooperates with the stirring shaft 221, the plug body 2212 is used to seal the discharge port 2123, the mounting plate 2214 is fixedly connected to the stirring shaft 221, the first elastic member 2213 is located between the plug body 2212 and the mounting plate 2214, and the two ends of the first elastic member 2213 are respectively fixedly connected to the plug body 2212 and the mounting plate 2214.

[0049] By setting the mounting plate 2214, the first elastic member 2213 and the plug body 2212, the stirring shaft 221 will drive the movement of the mounting plate 2214 when it moves along its axial direction. The movement of the mounting plate 2214 drives the movement of the first elastic member 2213 and the plug body 2212, so that the plug body 2212 can be inserted into the discharge port 2123 of the partition 212 to block the discharge port 2123 of the partition 212, thereby enabling the material in the premixing chamber 2121 to be intermittently fed into the stirring chamber 2122, so that the material can be better crushed in the premixing chamber 2121, thereby improving the subsequent mixing of the material into the stirring chamber 2122, and the first elastic member 2213 can buffer the impact force when the plug body 2212 and the partition 212 abut, thereby extending the service life of the equipment.

[0053] Since the axis of the mixing drum 2 is inclined, when the lower cylinder 22 rotates around the main axis 11, its first mounting shaft 224 will generate movement around the main axis 11, and the second mounting shaft 142 can match the movement of the position of the first mounting shaft 224 through the setting of the rotatable support seat 14 and the slide groove 141. The second elastic member 143 can buffer the lower cylinder 22 when it slides toward the bottom of the frame 1. The support seat 14 can support the lower cylinder 22, thereby extending the service life of the equipment.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
