Description

Technical Field

[0001] The present application relates to the technical field of organic fertilizer production devices, and in particular to an organic fertilizer seedling bed powder production device. Background Art

[0002] Organic fertilizer seedbed powder is a form of organic fertilizer used for seedbed soil conditioning and nutrient supplementation. It transforms organic waste into a stable and efficient source of plant nutrition through microbial fermentation and other processes. Organic fertilizer seedbed powder contains a large number of nutrients such as nitrogen, phosphorus, potassium, as well as a variety of trace elements and organic matter. These ingredients can not only provide plants with necessary nutrients, but also improve soil structure, increase soil aeration and water retention, promote soil microbial activity, and benefit plant root growth.

[0003] Organic fertilizer seedling bed powder is made from organic matter (such as animal and plant residues, livestock excrement, etc.) after fermentation and decomposition, and then processed into powdered finished products through processes such as crushing, screening, stirring, and packaging. A pulverizer is a device for crushing organic fertilizer raw materials in the production process of organic fertilizer seedling bed powder. For example, the invention application with publication number CN104475209A discloses a kind of organic fertilizer crushing and screening machine, which includes a frame and a crushing box, and a feed port and a discharge port are provided on the crushing box. A crushing chamber and a screening chamber are installed in the crushing box, and two crushing shafts are installed in the crushing chamber, and crushing blades are installed at intervals on the crushing shaft, and a screening chamber is installed below the crushing shaft, and a filter device is installed in the screening chamber. When it is necessary to crush organic fertilizer, the organic fertilizer is sent into the crushing chamber, and then the crushing shaft is driven to rotate, and the organic fertilizer is crushed by the crushing blades on the crushing shaft.

[0004] In the actual production process of organic fertilizer seedbed powder, different batches of products have different requirements for the particle size of the finished powder. However, the spacing between adjacent crushing blades on the crushing shaft of the above-mentioned organic fertilizer crushing and screening machine is fixed. If the spacing between adjacent crushing blades is too wide, when the particle size of the finished organic fertilizer seedbed powder is required to be smaller, the finished product with smaller particle size can only be obtained by increasing the speed of the crushing shaft drive motor or extending the residence time of the organic fertilizer in the crushing chamber, which will increase energy consumption and the energy saving effect is not very ideal. If the spacing between adjacent crushing blades is too narrow, when the particle size of the finished organic fertilizer seedbed powder is required to be larger, the too narrow crushing blade spacing may affect the feeding speed of the organic fertilizer, thereby affecting the production efficiency of the organic fertilizer seedbed powder. Summary of the invention

[0005] The purpose of the present application is to provide an organic fertilizer seedling bed powder production device to solve the problem that the organic fertilizer crushing and screening machine in the related art cannot balance the energy saving effect and production efficiency well.

[0015] Optionally, the sieve plates are provided with two pieces, and the two sieve plates are slidably and detachably arranged on the crushing bin and can be spliced ​​with each other. The crushing bin is provided with a locking mechanism, which can be connected to the sieve plates and is used to limit the sliding of the sieve plates relative to the crushing bin.

[0016] By adopting the above technical solution, the sieve plate is set into two pieces and locked with the crushing bin through a locking mechanism. When the sieve plate needs to be replaced, it is only necessary to operate the locking mechanism to unlock it, and then remove the two sieve plates from both sides of the two rollers and move them out of the crushing bin, thereby facilitating the disassembly operation of the sieve plate.

[0017] Optionally, the locking mechanism includes a wedge block and an elastic member, the screen plate is provided with a locking groove, the crushing bin is provided with a slide groove, the wedge block is slidably arranged in the slide groove and can be engaged with the locking groove of the screen plate, the elastic member is arranged on the crushing bin and acts on the wedge block, and the elastic member is used to provide an elastic force to push the wedge block toward the locking groove.

[0018] By adopting the above technical solution, when the sieve plate needs to be locked by the locking mechanism, it is only necessary to slide the sieve plate to the position where the locking groove and the wedge block are relative to each other, so that the wedge block is engaged with the locking groove under the elastic force of the elastic member, and the sieve plate can be locked, thereby improving the operational convenience when the sieve plate is installed in the crushing bin.

[0019] Optionally, it also includes a bin door, which is slidably arranged on both sides of the crushing bin and connected to the crushing bin through a locking piece, the crushing bin is provided with a first guide rail, the screen plate is slidably arranged on the first guide rail, the crushing bin is provided with a strip groove, the screen plate is provided with a handle, and the handle passes through the strip groove and extends to the outside of the crushing bin.

[0022] By adopting the above technical solution, when it is necessary to adjust the spacing between adjacent crushing knives along the axial direction of the roller shaft, it is only necessary to set a set of adjusting gears and racks between every two adjacent bases, and drive each set of adjusting gears to rotate through a rotating driving member, and then under the interaction of each set of adjusting gears and racks, the adjacent bases can be driven to move relative to each other, thereby achieving the purpose of adjusting the spacing between adjacent crushing knives.

[0024] By adopting the above technical solution, by respectively arranging the first transmission rod and the first connection hole that are slidably plugged into each other on the rotating shafts of adjacent bases, the rotating shafts on the adjacent bases can maintain synchronous rotation and can be telescopically moved along the axial direction. Therefore, when adjusting the spacing between adjacent crushing knives along the axial direction of the roller shaft, even if the distance between the adjacent bases changes, the rotating shafts on each group of bases can maintain transmission connection, thereby driving each group of adjustment gears to rotate synchronously.

[0025] Optionally, it also includes a telescopic driving mechanism, which includes a turntable and a slider, the turntable is rotatably arranged on the base, the turntable is provided with a first planar thread, the slider is radially slidably arranged on the base, the slider is provided with a second planar thread meshing with the first planar thread, the crushing knife is fixedly connected to the slider, and the turntables on adjacent bases are provided with a cylinder and a second transmission rod which are slidably plugged into each other.

When the turntable rotates, under the interaction of the first plane thread and the second plane thread, the slider is driven to slide along the radial direction of the base, thereby driving multiple groups of crushing knives to move simultaneously in the radial direction of the roller shaft, and adjusting the length of the crushing knife extending out of the roller shaft.

[0027] Optionally, it also includes a plurality of layers of sliding sleeves, the plurality of layers of sliding sleeves are stacked and slidingly sleeved on the outside of the roller shaft, the sliding sleeve is provided with a through groove, the crushing knife slides through the through groove, the roller shaft is provided with a plurality of avoidance grooves for avoiding the crushing knife respectively, the lengths of the plurality of avoidance grooves increase successively along the axial direction of the roller shaft, and the sliding sleeve cover is arranged on the outside of the avoidance groove.

Therefore, the organic fertilizer seedbed powder production device of the present application sets the lengths of the multiple avoidance grooves to increase successively along the axial direction of the roller shaft, so as to adapt to the moving distances of different crushing knives.

[0029] When the spacing between adjacent crushing knives is adjusted by the spacing adjustment mechanism, the sliding sleeve moves along the axial direction of the roller together with the crushing knives. Since the multi-layer sliding sleeves are stacked and slidingly sleeved on the outside of the roller, the sliding sleeve can always be covered on the outside of the avoidance groove during the movement of the crushing knives, thereby preventing the organic fertilizer raw materials in the crushing bin from entering the inside of the roller through the avoidance groove during the crushing process.

[0033] By adopting the above technical solution, when the radial distance between the two rollers needs to be adjusted, the sliding plate is driven by the sliding drive member to slide radially along the rollers, thereby driving the rollers on the sliding plate to move to achieve the adjustment of the radial distance.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

Under the interaction of the adjusting gear 311 and the rack 312, the adjacent bases 31 are driven to move relatively along the axial direction of the roller shaft 20, so as to adjust the spacing between the crushing knives 80 on the adjacent bases 31.

[0087] When adjusting the spacing between adjacent crushing knives 80 along the axial direction of the roller shaft 20, the axial screw 70 is rotated, and the end plate 120 is driven to move along the axial direction of the roller shaft 20 under the interaction between the axial screw 70 and the axial screw hole 19 to adapt to the axial position change of the crushing knives 80 along the roller shaft 20. When the crushing knives 80 move along the axial direction of the roller shaft 20, the sliding sleeve 110 is driven to move at the same time, thereby adjusting the position of the sliding sleeve 110 so that the sliding sleeve 110 can always block the avoidance groove 22, thereby preventing the organic fertilizer raw materials from entering the inside of the roller shaft 20 through the avoidance groove 22 during the crushing process.

[0088] Then, the radial screw rod 42 is rotated, and the interaction between the radial screw rod 42 and the radial screw hole 150 drives the slide plate 41 to slide along the radial direction of the roller shaft 20 to adjust the distance between the two roller shafts 20. Then, the driving shaft 615 is rotated, and the rotating disk 61 is driven to rotate by the driving shaft 615. Under the interaction between the first plane thread 611 and the second plane thread 621, the slide plate 62 is driven to slide along the radial direction of the base 31, thereby driving the crushing knife 80 to move in the radial direction of the roller shaft 20, and adjusting the length of the crushing knife 80 extending out of the roller shaft 20.

[0089] Then, a new sieve plate 90 matched with the adjusted roller shaft 20 and the crushing knife 80 is installed in the crushing bin 10, and the bin door 100 is closed, thereby completing the adjustment of the organic fertilizer seedling bed powder production device of the present application to adapt to the required crushing particle size of the organic fertilizer seedling bed powder finished product.
