Description
Technical Field
[0001] The utility model relates to grain leveling equipment in the field of bulk grain storage, in particular to a scraper type bulk grain leveling device. Background Art
[0002] In bulk grain storage operations, after the bulk grain is transported to the grain warehouse through conveying equipment, the top of the bulk grain needs to be leveled using grain leveling equipment.
[0003] There are many kinds of existing grain leveling equipment, among which the traditional grain leveling equipment includes an equipment bracket, a front grain leveling structure is arranged on the front side of the equipment bracket, and a rear grain leveling structure is arranged on the rear side of the equipment bracket. The grain leveling structure can be an auger driven by a motor. When working, the equipment bracket can move forward and backward along the surface of the grain pile under the drive of the corresponding driving mechanism. When the equipment bracket moves from back to front, the front grain leveling structure performs grain leveling work; when the equipment bracket moves from front to back, the rear grain leveling structure performs grain leveling work, thereby realizing the grain leveling operation on the surface of the grain pile by moving the equipment bracket forward and backward.

The large number of grain leveling structures will increase the weight and production cost of the grain leveling equipment. The increase in the weight of the grain leveling equipment will increase the energy consumption of the driving mechanism. Utility Model Content

The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification.

[0025] The utility model is a scraper type bulk grain leveling device. Figures 1 to 5 As shown: it includes an equipment bracket that can move forward and backward under the corresponding driving mechanism. The driving mechanism can be a mobile trolley that can move forward and backward along the track on the silo roof. In this embodiment, the driving mechanism is not a part of the scraper type grain leveling device. In other embodiments of the utility model, the driving mechanism can also be a part of the scraper type grain leveling device.
[0026] The equipment support includes a telescopic support 1 and a grain pushing support 2 extending in the left-right direction. The telescopic support includes multiple support sections 3 that are sequentially telescopically matched in the up-down direction. The uppermost support section is used to connect with the driving mechanism, and the grain pushing support is fixed to the lowermost support section 3. The up-down telescopic movement of each support section is achieved by a vertically arranged driving cylinder (not shown in the figure).
[0027] A left scraper 4 and a right scraper 5 are arranged at the bottom of the grain pushing bracket 2. The left end of the left scraper 4 is rotatably connected to the grain pushing bracket 2 through a left rotating connection structure, and the right end of the right scraper 5 is rotatably connected to the grain pushing bracket 2 through a right rotating connection structure. The rotation axes of the left rotating connection structure and the right rotating connection structure are extended along the up and down directions. In this embodiment, the left rotating connection structure and the right rotating connection structure both include a vertically arranged fixed shaft and a rotating sleeve connected to the fixed shaft, and the left scraper and the right scraper are fixedly connected to the corresponding rotating sleeves.
[0028] The grain pushing bracket is provided with a right scraper stopping structure 18 for limiting the rearward swinging limit of the right scraper during the forward movement of the equipment bracket, and the right end of the left scraper has a left scraper pushing portion for cooperating with the front pushing of the left end of the right scraper; the grain pushing bracket is provided with a left scraper stopping structure 7 for limiting the forward swinging limit of the left scraper during the backward movement of the equipment bracket, and the left end of the right scraper has a right scraper pushing portion for cooperating with the rear pushing of the right end of the left scraper, and the left scraper stopping structure and the right scraper stopping structure are arranged at intervals in front and back.
[0029] In this embodiment, the left scraper stopping structure and the right scraper stopping structure are both vertically arranged stop rod structures.
[0030] The right scraper stop structure 18 is located at the rear side of the line connecting the rotation axes of the left scraper 4 and the right scraper 5; the left scraper stop structure 7 is located at the front side of the line connecting the rotation axes of the left scraper and the right scraper. The left scraper push portion is arranged at the rear side of the right end of the left scraper; the right scraper push portion is arranged at the front side of the left end of the right scraper.
[0031] In order to ensure the strength of the left scraper and the right scraper, a left arc track 11 coaxially arranged with the left scraper and a right arc track 12 coaxially arranged with the right scraper are also fixed at the bottom of the equipment bracket. The left scraper 4 is provided with a left guide block which cooperates with the left arc track 11 for guiding movement, and the right scraper 5 is provided with a right guide block which cooperates with the right arc track 12 for guiding movement.

[0032] The equipment bracket is provided with a right trigger member 14 at the front end for cooperating with the front warehouse wall to push and a left trigger member 13 at the rear end for cooperating with the rear warehouse wall to push. The right trigger member 14 is connected to the right scraper for transmission so that when the right trigger member pushes the front warehouse wall, the left end of the right scraper rotates forward; the left trigger member 13 is connected to the left scraper for transmission so that when the left trigger member pushes the rear warehouse wall, the right end of the left scraper rotates backward.
[0033] In this embodiment, the left trigger member and the right trigger member are both trigger rod structures with a length extending in the front-to-back direction. Each trigger member is guided and moved along the front-to-back direction and assembled on the grain pushing bracket. The grain pushing bracket is fixed with guide rods 17 extending in the front-to-back direction in the guiding directions respectively arranged corresponding to each trigger member, and each trigger member is guided and moved respectively and assembled on the corresponding guide rod.

When moving from back to front, Figure 2 As shown, under the reaction force of the loose grain on the surface of the grain pile, the right scraper swings backward and is stopped by the right scraper stopping structure, the left scraper swings backward and is stopped by the right scraper, and the loose grain is scraped flat by the left and right scrapers; when the right trigger member pushes against the front silo wall of the granary, the right trigger member moves backward and swings the left end of the right scraper forward, the right scraper swings forward with the right end of the left scraper, and is stopped by the right scraper stopping structure, reaching the maximum forward swinging limit, and then the driving mechanism moves the equipment bracket from front to back to realize the grain leveling operation during reverse movement.
[0036] In the present invention, only a left scraper and a right scraper need to be set. The left scraper and the right scraper constitute a group of grain leveling mechanisms. The posture adjustment is achieved by the swinging of the left scraper and the right scraper, so as to cooperate with the grain leveling operation when the equipment bracket moves back and forth. Compared with the two augers in the prior art, the structure is simpler and lighter.
