Description

Technical Field

[0001] The present invention relates to a training device for ammunition use and safety, and particularly to a movable combined grenade throwing training device. Background Art

[0002] Grenades are commonly used in combat by troops as throwing ammunition with relatively large lethality, and are important weapons for infantry in assault and defensive operations. To improve the actual combat training level of troops and enhance the combat awareness of officers and soldiers, our army has been conducting grenade throwing subject training. Grenade throwing has become one of the essential military skills in tactics.

[0003] Due to the large killing power of grenades and high throwing risks, serious consequences of casualties will occur if they miss. During the new recruit training period, for recruits without throwing experience, the psychological pressure is high during the first throw. The nervous and excited psychology will greatly increase the throwing risk. New soldiers are very likely to have throwing fractures due to deformed movements, or make throwing mistakes due to nervousness and fear, resulting in the grenade slipping out of the hand and causing an injury accident of an explosion at close range. Due to the limitations of troops' training conditions and from the perspective of safety, during normal training, grenade throwing training is mainly carried out through two methods: safety theory explanation and construction of safety protection facilities. However, these two methods still cannot completely eliminate the fear psychology of the trainees and avoid the injury accidents caused by the grenade slipping out of the hand. In this way, the difficulty of grenade throwing training is increased.

[0004] In view of the above reasons, it is very necessary to develop a device suitable for grenade throwing training to improve the training level of grenade throwing and ensure the safe and smooth progress of grenade throwing training. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a grenade throwing training device that can move its position according to the needs of training, avoid grenade throwing mistakes, and reduce the explosion risk.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a grenade throwing training device, mainly including a throwing shelter, a throwing tube, and an explosion funnel;

[0007] The throwing shelter is installed on a relatively flat ground of the training ground. The throwing shelter includes a bottom plate, a front baffle, a rear baffle, a left baffle, and a right baffle. The four front, rear, left, and right baffles are vertically installed on the four sides of the bottom plate to form the throwing shelter; among them,

[0008] The length of the rear baffle is less than the length of the front baffle, forming an inlet and outlet of the throwing shelter. The throwing shelter is divided into a connected throwing chamber and a shelter chamber by a vertically installed L-shaped partition;

[0009] The height of the front baffle of the throwing chamber is lower than that of the front baffle of the shelter chamber, forming a throwing opening. A mine pit is dug in the ground at the bottom of the throwing chamber. A throwing platform is provided on the bottom plate of the throwing chamber. A circular arc-shaped throwing pedal is provided on the top of the throwing platform. The left and right ends of the throwing pedal extend towards the partition board and the right baffle of the throwing chamber. On the bottom plates on the left and right sides of the throwing platform, lightning fall grooves communicating with the mine pit are opened. Inclined slide plates are symmetrically arranged on the upper sides of the left and right lightning fall grooves. There are gaps for grenades to fall between the left and right slide blocks and the left and right edges of the throwing pedal. The left and right bending lightning fall channels for guiding the rolling grenades into the mine pit are formed by the gaps, the slide plates, the lightning fall grooves and the mine pit;

[0010] The explosion funnel is arranged in front of the throwing shelter chamber;

[0011] The throwing tube is inclined and installed between the throwing chamber and the explosion funnel.

[0012] Furthermore, jack holes are provided on the four sides of the bottom plate. Bolts corresponding to the jack holes are respectively provided on the bottom side edges of the front baffle, the rear baffle, the left baffle and the right baffle. The front baffle, the rear baffle, the left baffle and the right baffle are respectively hinged on the four edges of the bottom plate and are vertically fixed by inserting the bolts into the jack holes to form a throwing shelter chamber with an open top. The front baffle, the rear baffle, the left baffle, the right baffle and the bottom plate are all made of steel materials.

[0013] Furthermore, an elevation support is provided at the bottom of the throwing shelter chamber to meet the needs of long-distance throwing training. A ladder for facilitating entry into the throwing shelter chamber is provided on the elevation support.

[0014] Furthermore, the throwing platform is a rectangular steel throwing platform, which is welded on the upper surface of the bottom plate of the throwing chamber.

[0015] Furthermore, the throwing pedal is a downward-bent circular arc-shaped steel throwing pedal. The throwing pedal is welded on the top of the throwing platform. Anti-slip grid patterns are provided on the top surface of the throwing pedal. The left and right ends of the throwing pedal form two barrier barriers for buffering the rapid outrush of explosion air flow from the bending lightning fall channels.

[0016] Furthermore, the explosion funnel is a detachable explosion funnel, which is installed on the ground in front of the throwing chamber through a mounting frame and ground anchor bolts. The bottom of the explosion funnel is provided with holes, and the surrounding inner walls incline towards the bottom. Sand for buffering is filled in the explosion funnel. Lugs for handling or hoisting are respectively provided on the upper edges of the left and right side walls of the explosion funnel.

[0017] Furthermore, the throwing tube has a conical structure. The conical throwing tube can be longitudinally unfolded along its conical wall into an open throwing tube. The conical throwing tube is inclinedly installed between the throwing chamber and the explosion funnel through a support frame. The upper end of the throwing tube is connected to the throwing port, and the lower end is connected to the explosion funnel. The inclination angle of the throwing tube is 15 - 30°.

[0018] Furthermore, the throwing tube is a spliced groove-type throwing tube, and the number of groove-type throwing tubes can be increased or decreased according to the throwing distance. The groove-type throwing tube is inclinedly installed between the throwing chamber and the explosion funnel through a support frame. The upper end of the throwing tube is connected to the throwing port, and the lower end is connected to the explosion funnel. The inclination angle of the throwing tube is 15 - 30°.

[0019] Furthermore, the support frame is formed by welding two long columns, two short columns and a cross beam. Among them, the short columns are in the front and the long columns are in the back. Support pieces are horizontally arranged at the bottom of each column, and arc-shaped brackets for facilitating the installation of the throwing tube are respectively arranged at the tops of the two long columns and the two short columns.

[0020] Furthermore, the skateboards are respectively inclinedly arranged at the upper edges of the two lightning strike troughs on the side far from the throwing platform. The upper end of the skateboard on the left is connected to the partition board, and the upper end of the skateboard is higher than the left edge of the throwing pedal. The upper end of the skateboard on the right is connected to the right baffle, and the upper end of the skateboard is higher than the right edge of the throwing pedal.

[0021] Based on the above technical solutions, the present invention has at least the following beneficial effects compared with the prior art:

[0022] 1. The structure of the present invention is simple. The explosion funnel, the throwing tube, and the throwing shelter can be independently disassembled and installed. The installation, disassembly, and movement are convenient, and it can be transported to different areas for training according to actual needs.

[0023] 2. The training is safe and reliable. The throwing shelter is divided into a throwing chamber and a shelter. Curved lightning strike channels are arranged on both sides of the arc-shaped throwing pedal in the throwing chamber. The accidentally dropped grenade will not stay on the pedal and will roll from the arc-shaped pedal into the lightning strike channel and fall into the mine pit to explode. The blocking barriers formed at both ends of the throwing pedal can weaken the explosion air flow rushing out, ensuring the safety of the trainers. The shelter can be used for the instructor to teach and ensure that the trainer can quickly enter the shelter for safety shelter after throwing. It greatly eliminates the fear psychology of the soldiers, reduces the tension and error rate of the new soldiers when throwing grenades for the first time, enables the soldiers to feel the explosion more safely and at a closer distance, and can not only enable the soldiers to meet the training standards but also ensure the safety of the soldiers.

[0024] 3. The throwing tube is used to restrict the movement space of the grenade. By installing it inclinedly, it can ensure that the grenade falls into the explosion funnel.

[0025] 4. The explosion funnel can withstand the explosion of training grenades without being damaged. There are holes at the bottom of the explosion funnel, and the surrounding walls slope towards the bottom, which can ensure that the lightning strikes penetrate deep into the bottom of the explosion funnel. When the explosion funnel is moved, sand and gravel can naturally fall out. When not in training, the explosion funnel can be used alone as an emergency destruction operation device for explosives.

[0026] In summary, the grenade throwing training device of the present invention has at least the above-mentioned many advantages and practical values, and there is no similar product publicly published or used in the same type of products, which is indeed innovative, producing a good and practical effect, having an improved technical effect compared with the existing technology, thus being more suitable for practical use, having a wide industrial value, and being suitable for popularization and application.

[0039] The throwing shelter 4 is installed on a relatively flat ground of the training ground. The throwing shelter 4 includes a bottom plate 5, a front baffle 6, a rear baffle 7, a left baffle 8, and a right baffle 9. The four front, rear, left, and right baffles are vertically installed on the four sides of the bottom plate 5 to form the throwing shelter. Among them,

[0040] the length of the rear baffle 7 is less than the length of the front baffle 6, forming an inlet / outlet 17 of the throwing shelter. The throwing shelter is divided into a connected throwing chamber and a shelter chamber by a vertically installed L-shaped partition 10.

[0041] The height of the front baffle 6 of the throwing chamber is lower than that of the front baffle 6 of the shelter chamber, forming a throwing opening 18. A mine pit is dug downward on the ground at the bottom of the throwing chamber. A throwing platform 19 is provided on the bottom plate 5 of the throwing chamber. A circular arc-shaped throwing pedal 20 is provided on the top of the throwing platform 19. The left and right ends of the throwing pedal 20 extend towards the partition 10 and the right baffle 9 of the throwing chamber. Falling mine grooves 22 communicating with the mine pit are opened on the bottom plate 5 on the left and right sides of the throwing platform 19. Inclined sliding plates 23 are symmetrically arranged above the left and right falling mine grooves 22. Gaps 21 allowing grenades to fall through are left between the left and right sliding plates 23 and the left and right edges of the throwing pedal 20. The gaps 21, the sliding plates 23, the falling mine grooves 22 and the mine pit form left and right curved mine-falling channels for introducing the rolling grenades into the mine pit.

[0042] The explosion funnel 1 is arranged in front of the throwing shelter 4.

[0043] The throwing tube 2 is inclined and installed between the throwing chamber and the explosion funnel 1.

[0044] Use of the above-mentioned grenade throwing training device:

[0045] When the above-mentioned grenade throwing training device needs to be used, pull the components of the explosion funnel 1, the throwing tube 2, the throwing shelter 4 and the support frame 3 to the training ground. Dig a preset mine pit downward on the ground of the training ground. Hinge the bottom edges of the front baffle 6, the rear baffle 7, the left baffle 8 and the right baffle 9 to the four sides of the bottom plate 5 to form a rectangular throwing shelter with an open upper end. Then, vertically install the L-shaped partition 10 to divide the throwing shelter into a communicating throwing chamber and a shelter chamber. Place the bottom of the throwing chamber of the installed throwing shelter opposite to the previously dug mine pit. Then, install the throwing tube 2 inclinedly through the support frame 3. The upper end of the throwing tube 2 is connected to the throwing opening 17 of the throwing chamber, and the lower end of the throwing tube 2 is installed with the explosion funnel 1. After the installation is completed, the trainer can conduct training through this throwing training device.

[0046] The grenade throwing training device provided by the present invention has the above structure, which is simple. The explosion funnel, throwing tube, and throwing shelter can be independently disassembled and installed, and the installation, disassembly, movement, and replacement are convenient. It can be transported to different areas for training according to actual needs. The training is safe and reliable. The throwing shelter is divided into a throwing room and a shelter. Curved lightning channels are provided on both sides of the arc-shaped throwing pedal in the throwing room. The accidentally dropped grenade will not stay on the pedal, but will roll from the arc-shaped pedal into the lightning channel and fall into the mine pit to explode. After the soldier holds the grenade and stands on the throwing area in the throwing room, he can easily and naturally aim at the explosion funnel in front of him for throwing training. The shelter can be used for the instructor to teach and ensure that the trainer can quickly enter the shelter for safety shelter after throwing. This greatly eliminates the fear of soldiers, reduces the tension and error rate of new soldiers when throwing grenades for the first time, enables soldiers to feel the explosion safer and closer, and can not only enable soldiers to meet the training standards but also ensure the safety of soldiers. The throwing tube can restrict the movement space of the grenade. It is installed obliquely to ensure that the grenade accurately falls into the explosion funnel. The explosion funnel can withstand the explosion of the training grenade without being damaged. There are holes at the bottom of the explosion funnel, and the surrounding walls are inclined towards the bottom, which can ensure that the lightning penetrates to the bottom of the explosion funnel. When the explosion funnel is moved, the sand and gravel will naturally fall out. When not in training, the explosion funnel can be used alone as an explosive emergency destruction operation device.

[0047] In a schematic embodiment of the grenade throwing training device provided by the present invention, jacks are provided on the four sides of the bottom plate 5, and pins corresponding to the jacks are respectively provided on the side edges at the bottoms of the front baffle 6, rear baffle 7, left baffle 8, and right baffle 9. The front baffle 6, rear baffle 7, left baffle 8, and right baffle 9 are respectively hinged to the four edges of the bottom plate 5 and are vertically fixed by inserting the pins into the jacks to form a throwing shelter with an open top. In this way, the throwing shelter can be conveniently assembled, and at the end of the training, it can also be quickly disassembled for handling. Hoisting rings can also be installed on the tops of the left baffle 8 and the right baffle 9. In this way, when moving the site, the throwing shelter can be hoisted as a whole to the target site.

[0048] The front baffle 6, rear baffle 7, left baffle 8, right baffle 9, and bottom plate 5 are all made of steel materials, which can improve the strength of the throwing shelter, not only explosion-proof but also convenient for processing and manufacturing.

[0049] In a schematic embodiment of the grenade throwing training device provided by the present invention, a heightening bracket 24 is provided at the bottom of the throwing shelter 4, and a ladder 25 for easily entering the throwing shelter 4 is provided on the heightening bracket 24. In this way, the height of the throwing point is increased to meet the needs of long-distance throwing training, as Figure 5 shown.

[0050] In a schematic embodiment of the grenade throwing training device provided by the present invention, the throwing platform 19 is a rectangular steel throwing platform, welded to the upper surface of the bottom plate 5 of the throwing chamber, so that the throwing platform 19 is more firmly installed on the bottom plate 5 of the throwing chamber.

[0051] In a schematic embodiment of the grenade throwing training device provided by the present invention, the throwing pedal 20 is a downwardly curved arc-shaped steel throwing pedal, and the throwing pedal 20 is welded to the top of the throwing platform 19. As Figure 2 shown, the throwing pedal 20 is welded to the top of the throwing platform 19 in an umbrella shape. In this way, the accidentally dropped grenade will not stay on the top of the arc-shaped throwing pedal 20, but will roll into the lightning channel along the left or right. Anti-slip grid patterns are provided on the top surface of the throwing pedal 20 to play an anti-slip role, enabling the trainer to stand more stably on the throwing pedal 20. The left and right ends of the throwing pedal 20 form two blocking barriers that can buffer the rapid outrush of the explosion air flow from the curved lightning channel. When an explosion occurs, the explosion air flow can be effectively buffered.

[0052] In a schematic embodiment of the grenade throwing training device provided by the present invention, the explosion funnel 1 is a detachable explosion funnel, installed on the ground in front of the throwing chamber through the mounting frame 11 and the anchor bolts 12. There are holes at the bottom of the explosion funnel 1, and the surrounding walls inside slope towards the bottom, which can ensure that the lightning falls deep into the bottom of the explosion funnel 1. Sand for buffering is filled in the explosion funnel 1. After the grenade falls and explodes, the impact force is resolved by shaking off the sand and gravel. Lugs 13 for handling or hoisting are respectively provided along the upper edges of the left and right side walls of the explosion funnel 1. When not in training, the explosion funnel 1 can be used alone as an explosive emergency destruction operation device.

[0053] In a schematic embodiment of the grenade throwing training device provided by the present invention, the throwing tube 2 is a conical tube structure, obliquely installed between the throwing chamber and the explosion funnel 1 through the support frame 3. The upper end of the throwing tube 2 is connected to the throwing port 18, and the lower end is connected to the explosion funnel 1. The inclination angle of the throwing tube 2 is 30°. Installing it obliquely can restrict the movement space of the grenade and ensure that the grenade falls into the explosion funnel 1.

[0054] As Figure 3 shown, the conical throwing tube 2 can be longitudinally unfolded along its conical wall into an open throwing tube. Its installation is the same as that of the above-mentioned closed conical tube structure throwing tube, both are obliquely installed, the upper end is connected to the throwing port of the throwing chamber, and the lower end is connected to the explosion funnel 1. The open throwing tube has a wider field of vision. During training, the closed throwing tube or the open throwing tube can be selected according to actual needs.

[0055] In a schematic embodiment of the grenade throwing training device provided by the present invention, the throwing tube 2 is a spliced groove-type throwing tube. The groove-type throwing tubes 2 can be increased or decreased according to the throwing distance. The groove-type throwing tubes 2 are inclinedly installed between the throwing chamber and the explosion funnel 1 through the support frame 3. The upper end of the groove-type throwing tube 2 is connected to the throwing port 18, and the lower end is connected to the explosion funnel 1. The inclination angle of the groove-type throwing tube 2 is 25°. Designing the throwing tube 2 as a groove-type structure is not only convenient for processing and manufacturing, but also convenient for splicing. When performing long-distance throwing training, the groove-type throwing tubes 2 are increased and adjacent throwing tubes are spliced together. When relatively short-distance throwing training is required, the corresponding groove-type throwing tubes 2 are disassembled.

[0056] In a schematic embodiment of the grenade throwing training device provided by the present invention, the support frame 3 is formed by welding two long columns 14, two short columns 14 and a cross beam 15. Among them, the short columns are in the front and the long columns are in the back. At the bottom of each column 14, a support piece 16 is horizontally provided, which can make the support frame more firmly installed on the ground. Arc-shaped brackets for facilitating the installation of the throwing tube are respectively provided at the tops of the two long columns and the two short columns, so that the throwing tube 2 can be firmly installed between the explosion funnel 1 and the throwing chamber.

[0057] In a schematic embodiment of the grenade throwing training device provided by the present invention, the skateboards 23 are respectively inclinedly arranged at the upper edges of the two lightning fall grooves 22 on the side away from the throwing platform 19. The upper end of the left skateboard 23 is connected to the partition plate 10, and the upper end of the skateboard 23 is higher than the left edge of the throwing pedal 20. The upper end of the right skateboard is connected to the right baffle 9, and the upper end of the skateboard 23 is higher than the right edge of the throwing pedal 20. In this way, the accidentally fallen grenade will smoothly fall into the mine pit from the left or right curved lightning fall channels.

[0058] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
